S./Canada/Mexico-15546003) - 2022 - CRC - 5/12/21 8 Keys, Doors, and Windows { Warning If the key is unintentionally rotated while the vehicle is running, the ignition could be moved out of the RUN position. This could be caused by heavy items hanging from the key ring, or by large or long items attached to the key ring that could be contacted by the driver or steering wheel. If the ignition moves out of the RUN position, the engine will shut off, braking and steering power assist may be impacted, and airbags may not deploy. To reduce the risk of unintentional rotation of the ignition key, do not change the way the ignition key and Remote Keyless Entry (RKE) transmitter, if equipped, are connected to the provided key rings. The ignition key and key rings, and RKE transmitter, if equipped, are designed to work together as a system to reduce the risk of unintentionally moving the key out of the RUN position. The ignition key has a small hole to allow attachment of the provided key ring. It is important that any replacement ignition keys have a small hole. See your dealer if a replacement key is required. The combination and size of the rings that came with your keys were specifically selected for your vehicle. The rings are connected to the key like two links of a chain to reduce the risk of unintentionally moving the key out of the RUN position. Do not add any additional items to the ring attached to the ignition key. Attach additional items only to the second ring, and limit added items to a few essential keys or small, light items no larger than an RKE transmitter. Interference from radio-frequency identification (RFID) tags may prevent the key from starting the vehicle. Keep RFID tags away from the key when starting the vehicle. The key is used for the ignition, all door locks, and the glove box. If equipped with memory seats, keys 1 and 2 are linked to seating positions of memory 1 or 2. See Memory Seats 0 50. Programming Keys Follow these procedures to program up to eight keys to the vehicle. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

Repeat Steps 1–5 if additional keys are to be programmed. If a key is lost or damaged, see your dealer to have a new key made. Programming without Recognized Keys Program a new key to the vehicle when a recognized key is not available. Canadian regulations require that owners see their dealer. If two currently recognized keys are not available, follow this procedure to program the first key. This procedure will take approximately 30 minutes to complete for the first key. The vehicle must be off and all of the keys you wish to program must be with you. 1. Insert the new vehicle key into the ignition. 2. Turn the ignition on. The security light will come on. 3. Wait 10 minutes until the security light turns off. 4. Turn the ignition off. 5. Repeat Steps 2–4 two more times. After the third time, turn the ignition on; the key is learned and all previously known keys will no longer work with the vehicle. 6. To learn a second key, turn the ignition off, insert the second key to be learned, and turn the ignition on. After two keys are learned, the remaining keys can be learned by following the procedure in “Programming with Two Recognized Keys.” 9 The key has a bar-coded key tag that the dealer or qualified locksmith can use to make new keys. Store this information in a safe place, not in the vehicle. See your dealer if a replacement key or additional key is needed. If it becomes difficult to turn a key, inspect the key blade for debris. Periodically clean with a brush or pick. If locked out of the vehicle, see Roadside Assistance Program 0 412.

If this does not unlock the steering column, turn the vehicle off and open the driver door to reset the system. Then turn the vehicle on and immediately turn the steering wheel side to side for about 15 seconds. In some cases, it may take significant force to unbind the column. To keep the steering column from binding, straighten the front wheels before turning off the vehicle. Immobilizer See Radio Frequency Statement 0 417. Immobilizer Operation This vehicle has a passive theft-deterrent system. The system does not have to be manually armed or disarmed. The vehicle is automatically immobilized when the vehicle is turned off. The system is automatically disarmed when the ignition is turned from off to on. The security light, in the instrument cluster, comes on if there is a problem with arming or disarming the theft-deterrent system. The system has one or more RKE transmitters matched to an immobilizer control unit in your vehicle. Only a correctly matched RKE transmitter will start the vehicle. If the transmitter is ever damaged, you may not be able to start your vehicle. 33 When trying to start the vehicle, the security light may come on briefly when the ignition is turned on. If the engine does not start and the security light stays on, there is a problem with the system. Turn the ignition off and try again. If the vehicle will not change ignition modes (ACC/ACCESSORY, on, off), and the RKE transmitter appears to be undamaged, try another transmitter. Or, you may try placing the transmitter in the transmitter pocket located in the center console. See Remote Keyless Entry (RKE) System Operation (Key Access) 0 10 or Remote Keyless Entry (RKE) System Operation (Keyless Access) 0 13. If the ignition mode will not change with the other transmitter or with the transmitter in the transmitter pocket, your vehicle needs service. If the ignition does change modes, the first transmitter may be faulty. See your dealer who can service the theft-deterrent system and have a new RKE transmitter programmed to the vehicle. It is possible for the immobilizer system to learn new or replacement RKE transmitters. Up to eight transmitters can be programmed for the vehicle. To program additional transmitters, see "Programming Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

To fold the seat, slowly pull the seat cushion up. { Warning To return the seat to the normal seating position, slowly pull the seat cushion down. { Warning A seat belt that is improperly routed, not properly attached, or twisted will not provide the protection needed in a crash. The person wearing the belt could be seriously injured. After raising the rear seatback, always check to be sure that the seat belts are properly routed and attached, and are not twisted. If available, the buttons are on the rear of the center console. To operate, the engine must be running. Press M or L to heat the left or right outboard seat cushion. An indicator on the climate control display appears when this feature is on. Do not let anyone ride where a seat belt cannot be worn properly. In a crash, if you or your passenger(s) are not wearing seat belts, injuries can be much worse than if you are wearing seat belts. You can be seriously injured or killed by hitting things inside the vehicle harder or by being ejected from the vehicle. In addition, anyone who is not buckled up can strike other passengers in the vehicle. It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle. In a collision, passengers riding in these (Continued) Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 56 Seats and Restraints Warning (Continued) areas are more likely to be seriously injured or killed. Do not allow passengers to ride in any area of the vehicle that is not equipped with seats and seat belts. Always wear a seat belt, and check that all passenger(s) are restrained properly too. This vehicle has indicators as a reminder to buckle the seat belts. See Seat Belt Reminders 0 114. Why Seat Belts Work When riding in a vehicle, you travel as fast as the vehicle does. If the vehicle stops suddenly, you keep going until something stops you. It could be the windshield, the instrument panel, or the seat belts! When you wear a seat belt, you and the vehicle slow down together. There is more time to stop because you stop over a longer distance and, when worn properly, your strongest bones take the forces from the seat belts. That is why wearing seat belts makes such good sense. Questions and Answers About Seat Belts Q: Will I be trapped in the vehicle after a crash if I am wearing a seat belt? A: You could be — whether you are wearing a seat belt or not. Your chance of being conscious during and after a crash, so you can unbuckle and get out, is much greater if you are belted. Q: If my vehicle has airbags, why should I have to wear seat belts? A: Airbags are supplemental systems only. They work with seat belts — not instead of them. Whether or not an airbag is provided, all occupants still have to buckle up to get the most protection. Also, in nearly all states and in all Canadian provinces, the law requires wearing seat belts. How to Wear Seat Belts Properly Follow these rules for everyone's protection. There are additional things to know about seat belts and children, including smaller children and infants. If a child will be riding in the vehicle, see Older Children 0 73 or Infants and Young Children 0 74. Review and follow the rules for children in addition to the following rules. It is very important for all occupants to buckle up. Statistics show that unbelted people are hurt more often in crashes than those who are wearing seat belts. There are important things to know about wearing a seat belt properly. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Seats and Restraints { Warning You can be seriously injured, or even killed, by not wearing your seat belt properly. . Sit up straight and always keep your feet on the floor in front of you (if possible). . Wear the lap part of the belt low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones and you would be less likely to slide under the lap belt. If you slid under it, the belt would apply force on your abdomen. This could cause serious or even fatal injuries. . Wear the shoulder belt over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces. The shoulder belt locks if there is a sudden stop or crash. Never allow the lap or shoulder belt to become loose or twisted. 57 Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 58 Seats and Restraints { Warning Never wear the shoulder belt under both arms or behind your back. Never route the lap or shoulder belt over an armrest. { Warning The seat belt can be pinched if it is routed under plastic trim on the seat, such as trim around the rear seatback folding handle or side airbag. In a crash, pinched seat belts might not provide adequate protection. Never allow seat belts to be routed under plastic trim pieces. Always use the correct buckle for your seating position. You can be seriously injured or killed if the shoulder belt is worn behind your back, under your legs, or wrapped around your neck. The shoulder belt can tighten but cannot be loosened if it is locked. The shoulder belt locks when it is pulled all the way out of the retractor. It unlocks when the shoulder belt is allowed to go all the way back into the retractor, but it cannot do this if it is wrapped around you. You may have to cut the seat belt if it is locked and tightened around you. Lap-Shoulder Belt All seating positions in the vehicle have a lap-shoulder belt. The following instructions explain how to wear a lap-shoulder belt properly. 1. Adjust the seat, if the seat is adjustable, so you can sit up straight. To see how, see “Seats” in the Index. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Seats and Restraints 59 position on the seat, move the seat rearward or recline the seat until the shoulder belt retractor lock releases. Engaging the child restraint locking feature in the front outboard seating position may affect the passenger sensing system, if equipped. See Passenger Sensing System 0 67. 2. Pick up the latch plate and pull the belt across you. Do not let it get twisted. The lap-shoulder belt may lock if you pull the belt across you very quickly. If this happens, let the belt go back slightly to unlock it. Then pull the belt across you more slowly. If the shoulder portion of a passenger belt is pulled out all the way, the child restraint locking feature may be engaged. See Child Restraint Systems 0 76. If this occurs, let the belt go back all the way and start again. If the locking feature stays engaged after letting the belt go back to stowed If the webbing locks in the latch plate before it reaches the buckle, tilt the latch plate flat to unlock. 3. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. If the belt is not long enough, see Seat Belt Extender 0 61. Position the release button on the buckle so that the seat belt could be quickly unbuckled if necessary. If equipped with a shoulder belt height adjuster, move it to the height that is right for you. See "Shoulder Belt Height Adjuster" later in this section for instructions on use and important safety information. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 60 Seats and Restraints To unlatch the belt, push the button on the buckle. The belt should return to its stowed position. Always stow the seat belt slowly. If the seat belt webbing returns quickly to the stowed position, the retractor may lock and cannot be pulled out. If this happens, pull the seat belt straight out firmly to unlock the webbing, and then release it. If the webbing is still locked in the retractor, see your dealer. 4. To make the lap part tight, pull up on the shoulder belt. Before a door is closed, be sure the seat belt is out of the way. If a door is slammed against a seat belt, damage can occur to both the seat belt and the vehicle. Shoulder Belt Height Adjuster The vehicle may have a shoulder belt height adjuster for the driver and front outboard passenger positions. Adjust the height so the shoulder portion of the belt is on the shoulder and not falling off of it. The belt should be close to, but not contacting, the neck. Improper shoulder belt height adjustment could reduce the effectiveness of the seat belt in a crash. See How to Wear Seat Belts Properly 0 56. Push the release button to move the height adjuster to the desired position. After the adjuster is set to the desired position, try to move it down without pushing the release button to make sure it has locked into position. Seat Belt Pretensioners This vehicle has seat belt pretensioners for the front outboard occupants. Although the seat belt pretensioners cannot be seen, they are part of the seat belt assembly. They can help tighten the seat belts during the early stages of a moderate to severe frontal, near frontal, or rear crash if the threshold conditions for pretensioner activation are Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Seats and Restraints met. Seat belt pretensioners can also help tighten the seat belts in a side crash or rollover event. Pretensioners work only once. If the pretensioners activate in a crash, the pretensioners and probably other parts of the vehicle's seat belt system will need to be replaced. See Replacing Seat Belt System Parts after a Crash 0 62. Seat Belt Use During Pregnancy Seat Belt Extender Seat belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they do not wear seat belts. If the vehicle's seat belt will fasten around you, you should use it. A pregnant woman should wear a lap-shoulder belt, and the lap portion should be worn as low as possible, below the rounding, throughout the pregnancy. Safety System Check Do not sit on the outboard seat belt while entering or exiting the vehicle or at any time while sitting in the seat. Sitting on the seat belt can damage the webbing and hardware. Rear Seat Belt Comfort Guides Rear seat belt comfort guides may provide added seat belt comfort for older children who have outgrown booster seats and for some adults. When installed on a shoulder belt, the comfort guide positions the shoulder belt away from the neck and head. Comfort guides are available through your dealer for the rear outboard seating positions. Instructions are included with the comfort guides. 61 The best way to protect the fetus is to protect the mother. When a seat belt is worn properly, it is more likely that the fetus will not be hurt in a crash. For pregnant women, as for anyone, the key to making seat belts effective is wearing them properly. But if a seat belt is not long enough, your dealer will order you an extender. Only a GM dealer issued extender should be used. When you go in to order it, take the heaviest coat you will wear, so the extender will be long enough for you. To help avoid personal injury, do not let someone else use it, and use it only for the seat it is made to fit. The extender has been designed for adults. Never use it for securing child restraints. For more information on the proper use and fit of seat belt extenders see the instruction sheet that comes with the extender. Periodically check the seat belt reminder, seat belts, buckles, latch plates, retractors, shoulder belt height adjusters (if equipped), and seat belt anchorages to make sure they are all in working order. Look for any other loose or damaged seat belt system parts that might keep a seat belt system from performing properly. See your dealer to have it repaired. Torn, frayed, or twisted seat belts may not protect you in a crash. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 62 Seats and Restraints Torn or frayed seat belts can rip apart under impact forces. If a belt is torn or frayed, have it replaced immediately. If a belt is twisted, it may be possible to untwist by reversing the latch plate on the webbing. If the twist cannot be corrected, ask your dealer to fix it. Make sure the seat belt reminder light is working. See Seat Belt Reminders 0 114. Keep seat belts clean and dry. See Seat Belt Care 0 62. Seat Belt Care Keep belts clean and dry. Seat belts should be properly cared for and maintained. Seat belt hardware should be kept dry and free of dust or debris. As necessary, exterior hard surfaces and seat belt webbing may be lightly cleaned with mild soap and water. Ensure there is not excessive dust or debris in the mechanism. If dust or debris exists in the system please see the dealer. Parts may need to be replaced to ensure proper functionality of the system. { Warning Do not bleach or dye seat belt webbing. It may severely weaken the webbing. In a crash, they might not be able to provide adequate protection. Clean and rinse seat belt webbing only with mild soap and lukewarm water. Allow the webbing to dry. Replacing Seat Belt System Parts after a Crash { Warning A crash can damage the seat belt system in the vehicle. A damaged seat belt system may not properly protect the person using it, resulting in serious injury or even death in a crash. To help make sure the seat belt systems are working properly after a crash, have them inspected and any necessary replacements made as soon as possible. After a minor crash, replacement of seat belts may not be necessary. But the seat belt assemblies that were used during any crash may have been stressed or damaged. See your dealer to have the seat belt assemblies inspected or replaced. New parts and repairs may be necessary even if the seat belt system was not being used at the time of the crash. Have the seat belt pretensioners checked if the vehicle has been in a crash, or if the airbag readiness light stays on after you start the vehicle or while you are driving. See Airbag Readiness Light 0 114. Airbag System The vehicle has the following airbags: . A frontal airbag for the driver . A frontal airbag for the front outboard passenger . A seat-mounted side impact airbag for the driver . A seat-mounted side impact airbag for the front outboard passenger . A roof-rail airbag for the driver and the passenger seated directly behind the driver Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Seats and Restraints . A roof-rail airbag for the front outboard passenger and the passenger seated directly behind the front outboard passenger All vehicle airbags have the word AIRBAG on the trim or on a label near the deployment opening. For frontal airbags, the word AIRBAG is on the center of the steering wheel for the driver and on the instrument panel for the front outboard passenger. For seat-mounted side impact airbags, the word AIRBAG is on the side of the seatback or side of the seat closest to the door. For roof-rail airbags, the word AIRBAG is on the ceiling or trim. Airbags are designed to supplement the protection provided by seat belts. Even though today's airbags are also designed to help reduce the risk of injury from the force of an inflating bag, all airbags must inflate very quickly to do their job. Here are the most important things to know about the airbag system: 63 { Warning Warning (Continued) You can be severely injured or killed in a crash if you are not wearing your seat belt, even with airbags. Airbags are designed to work with seat belts, not replace them. Also, airbags are not designed to inflate in every crash. In some crashes seat belts are the only restraint. See When Should an Airbag Inflate? 0 65. unnecessarily close to any airbag, as you would be if sitting on the edge of the seat or leaning forward. Seat belts help keep you in position before and during a crash. Always wear a seat belt, even with airbags. The driver should sit as far back as possible while still maintaining control of the vehicle. The seat belts and the front outboard passenger airbags are most effective when you are sitting well back and upright in the seat with both feet on the floor. Wearing your seat belt during a crash helps reduce your chance of hitting things inside the vehicle or being ejected from it. Airbags are “supplemental restraints” to the seat belts. Everyone in the vehicle should wear a seat belt properly, whether or not there is an airbag for that person. { Warning Because airbags inflate with great force and faster than the blink of an eye, anyone who is up against, or very close to, any airbag when it inflates can be seriously injured or killed. Do not sit (Continued) Occupants should not lean on or sleep against the door or side windows in seating positions with seat-mounted side impact airbags and/or roof-rail airbags. { Warning Children who are up against, or very close to, any airbag when it inflates can be seriously injured or killed. Always secure children properly in the vehicle. To read how, see Older Children 0 73 or Infants and Young Children 0 74. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 64 Seats and Restraints The driver frontal airbag is in the center of the steering wheel. There is an airbag readiness light on the instrument cluster, which shows the airbag symbol. The system checks the airbag electrical system for malfunctions. The light tells you if there is an electrical problem. See Airbag Readiness Light 0 114. Where Are the Airbags? Driver Side Shown, Passenger Side Similar The front outboard passenger frontal airbag is in the passenger side instrument panel. The driver and front outboard passenger seat-mounted side impact airbags are in the side of the seatbacks closest to the door. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Seats and Restraints Warning (Continued) do not attach or put anything on the steering wheel hub or on or near any other airbag covering. Do not use seat accessories that block the inflation path of a seat-mounted side impact airbag. Driver Side Crew Cab Shown, Passenger Side Double and Regular Cabs Similar The roof-rail airbags for the driver, front outboard passenger, and second row outboard passengers are in the ceiling above the side windows. { Warning If something is between an occupant and an airbag, the airbag might not inflate properly or it might force the object into that person causing severe injury or even death. The path of an inflating airbag must be kept clear. Do not put anything between an occupant and an airbag, and (Continued) Never secure anything to the roof of a vehicle with roof-rail airbags by routing a rope or tie‐down through any door or window opening. If you do, the path of an inflating roof-rail airbag will be blocked. When Should an Airbag Inflate? This vehicle is equipped with airbags. See Airbag System 0 62. Airbags are designed to inflate if the impact exceeds the specific airbag system's deployment threshold. Deployment thresholds are used to predict how severe a crash is likely to be in time for the airbags to inflate and help restrain the occupants. The vehicle has electronic sensors that help the airbag system determine the severity of the impact. Deployment thresholds can vary with specific vehicle design. 65 Frontal airbags are designed to inflate in moderate to severe frontal or near frontal crashes to help reduce the potential for severe injuries, mainly to the driver's or front outboard passenger's head and chest. Whether the frontal airbags will or should inflate is not based primarily on how fast the vehicle is traveling. It depends on what is hit, the direction of the impact, and how quickly the vehicle slows down. Frontal airbags may inflate at different crash speeds depending on whether the vehicle hits an object straight on or at an angle, and whether the object is fixed or moving, rigid or deformable, narrow or wide. Frontal airbags are not intended to inflate during vehicle rollovers, rear impacts, or many side impacts. In addition, the vehicle has advanced technology frontal airbags. Advanced technology frontal airbags adjust the restraint according to crash severity. Seat-mounted side impact airbags are designed to inflate in moderate to severe side crashes depending on the location of the impact. Seat-mounted side impact airbags are not designed to inflate in frontal impacts, near frontal impacts, rollovers, Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 66 Seats and Restraints or rear impacts. A seat-mounted side impact airbag is designed to inflate on the side of the vehicle that is struck. Roof-rail airbags are designed to inflate in moderate to severe side crashes depending on the location of the impact. In addition, these roof-rail airbags are designed to inflate during a rollover or in a severe frontal impact. Roof-rail airbags are not designed to inflate in rear impacts. Both roof-rail airbags will inflate when either side of the vehicle is struck or if the sensing system predicts that the vehicle is about to roll over on its side, or in a severe frontal impact. In any particular crash, no one can say whether an airbag should have inflated simply because of the vehicle damage or repair costs. What Makes an Airbag Inflate? In a deployment event, the sensing system sends an electrical signal triggering a release of gas from the inflator. Gas from the inflator fills the airbag causing the bag to break out of the cover. The inflator, the airbag, and related hardware are all part of the airbag module. For airbag locations, see Where Are the Airbags? 0 64. How Does an Airbag Restrain? In moderate to severe frontal or near frontal collisions, even belted occupants can contact the steering wheel or the instrument panel. In moderate to severe side collisions, even belted occupants can contact the inside of the vehicle. Airbags supplement the protection provided by seat belts by distributing the force of the impact more evenly over the occupant's body. Rollover capable roof-rail airbags are designed to help contain the head and chest of occupants in the outboard seating positions in the first and second rows. The rollover capable roof-rail airbags are designed to help reduce the risk of full or partial ejection in rollover events, although no system can prevent all such ejections. But airbags would not help in many types of collisions, primarily because the occupant's motion is not toward those airbags. See When Should an Airbag Inflate? 0 65. Airbags should never be regarded as anything more than a supplement to seat belts. What Will You See after an Airbag Inflates? After frontal and seat-mounted side impact airbags inflate, they quickly deflate, so quickly that some people may not even realize the airbags inflated. Roof-rail airbags may still be at least partially inflated for some time after they inflate. Some components of the airbag module may be hot for several minutes. For location of the airbags, see Where Are the Airbags? 0 64. The parts of the airbag that come into contact with you may be warm, but not too hot to touch. There may be some smoke and dust coming from the vents in the deflated airbags. Airbag inflation does not prevent the driver from seeing out of the windshield or being able to steer the vehicle, nor does it prevent people from leaving the vehicle. { Warning When an airbag inflates, there may be dust in the air. This dust could cause breathing problems for people with a history of asthma or other breathing trouble. To avoid this, everyone in the (Continued) Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Seats and Restraints Warning (Continued) vehicle should get out as soon as it is safe to do so. If you have breathing problems but cannot get out of the vehicle after an airbag inflates, then get fresh air by opening a window or a door. If you experience breathing problems following an airbag deployment, you should seek medical attention. The vehicle has a feature that may automatically unlock the doors, turn on the interior lamps and hazard warning flashers, and shut off the fuel system after the airbags inflate. The feature may also activate, without airbag inflation, after an event that exceeds a predetermined threshold. After turning the ignition off and then on again, the fuel system will return to normal operation; the doors can be locked, the interior lamps can be turned off, and the hazard warning flashers can be turned off using the controls for those features. If any of these systems are damaged in the crash they may not operate as normal. { Warning A crash severe enough to inflate the airbags may have also damaged important functions in the vehicle, such as the fuel system, brake and steering systems, etc. Even if the vehicle appears to be drivable after a moderate crash, there may be concealed damage that could make it difficult to safely operate the vehicle. Use caution if you should attempt to restart the engine after a crash has occurred. In many crashes severe enough to inflate the airbag, windshields are broken by vehicle deformation. Additional windshield breakage may also occur from the front outboard passenger airbag. . Airbags are designed to inflate only once. After an airbag inflates, you will need some new parts for the airbag system. If you do not get them, the airbag system will not be there to help protect you in another crash. A new system will include airbag modules and possibly other parts. The service manual for the vehicle covers the need to replace other parts. 67 . The vehicle has a crash sensing and diagnostic module which records information after a crash. See Vehicle Data Recording and Privacy 0 418 and Event Data Recorders 0 419. . Let only qualified technicians work on the airbag systems. Improper service can mean that an airbag system will not work properly. See your dealer for service. Passenger Sensing System The vehicle has a passenger sensing system for the front outboard passenger position. The passenger airbag status indicator will light on the overhead console when the vehicle is started. United States Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 68 Seats and Restraints Whenever possible, children aged 12 and under should be secured in a rear seating position. Canada The words ON and OFF, or the symbols for on and off, will be visible during the system check. When the system check is complete, either the word ON or OFF, or the symbol for on or off, will be visible. See Passenger Airbag Status Indicator 0 115. The passenger sensing system turns off the front outboard passenger frontal airbag under certain conditions. No other airbag is affected by the passenger sensing system. The passenger sensing system works with sensors that are part of the front outboard passenger seat and seat belt. The sensors are designed to detect the presence of a properly seated occupant and determine if the front outboard passenger frontal airbag should be allowed to inflate or not. According to accident statistics, children are safer when properly secured in a rear seat in the correct child restraint for their weight and size. Never put a rear-facing child seat in the front. This is because the risk to the rear-facing child is so great, if the airbag inflates. { Warning A child in a rear-facing child restraint can be seriously injured or killed if the passenger frontal airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag. A child in a forward-facing child restraint can be seriously injured or killed if the passenger frontal airbag inflates and the passenger seat is in a forward position. Even if the passenger sensing system has turned off the passenger frontal airbag, no system is fail-safe. No one can guarantee that an airbag will not deploy under some unusual circumstance, even though the airbag is turned off. (Continued) Warning (Continued) Never put a rear-facing child restraint in the front seat, even if the airbag is off. If securing a forward-facing child restraint in the front outboard passenger seat, always move the seat as far back as it will go. It is better to secure child restraints in the rear seat. Consider using another vehicle to transport the child when a rear seat is not available. If the vehicle does not have a rear seat that will accommodate a rear-facing child restraint, a rear-facing child restraint should not be installed in the vehicle, even if the airbag is off. The passenger sensing system is designed to turn off the front outboard passenger frontal airbag if: . The front outboard passenger seat is unoccupied. . The system determines an infant is present in a child restraint. . A front outboard passenger takes his/her weight off of the seat for a period of time. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Seats and Restraints . There is a critical problem with the airbag system or the passenger sensing system. When the passenger sensing system has turned off the front outboard passenger frontal airbag, the OFF indicator will light and stay lit as a reminder that the airbag is off. See Passenger Airbag Status Indicator 0 115. The passenger sensing system is designed to turn on the front outboard passenger frontal airbag anytime the system senses that a person of adult size is sitting properly in the front outboard passenger seat. When the passenger sensing system has allowed the airbag to be enabled, the ON indicator will light and stay lit as a reminder that the airbag is active. For some children, including children in child restraints, and for very small adults, the passenger sensing system may or may not turn off the front outboard passenger frontal airbag, depending upon the person's seating posture and body build. Everyone in the vehicle who has outgrown child restraints should wear a seat belt properly — whether or not there is an airbag for that person. { Warning If the airbag readiness light ever comes on and stays on, it means that something may be wrong with the airbag system. To help avoid injury to yourself or others, have the vehicle serviced right away. See Airbag Readiness Light 0 114 for more information, including important safety information. If the On Indicator Is Lit for a Child Restraint The passenger sensing system is designed to turn off the front outboard passenger frontal airbag if the system determines that an infant is present in a child restraint. If a child restraint has been installed and the ON indicator is lit: 1. Turn the vehicle off. 2. Remove the child restraint from the vehicle. 3. Remove any additional items from the seat such as blankets, cushions, seat covers, seat heaters, or seat massagers. 69 4. Reinstall the child restraint following the directions provided by the child restraint manufacturer and refer to Securing Child Restraints (With the Seat Belt in the Center Front Seat) 0 95 or Securing Child Restraints (With the Seat Belt in the Rear Seat) 0 89 or Securing Child Restraints (With the Seat Belt in the Front Passenger Seat) 0 93. Make sure the seat belt retractor is locked by pulling the shoulder belt all the way out of the retractor when installing the child restraint, even if the child restraint is equipped with a seat belt lock off. When the retractor lock is set, the belt can be tightened but not pulled out of the retractor. 5. If, after reinstalling the child restraint and restarting the vehicle, the ON indicator is still lit, turn the vehicle off. Then slightly recline the vehicle seatback and adjust the seat cushion, if adjustable, to make sure that the vehicle seatback is not pushing the child restraint into the seat cushion. Also make sure the child restraint is not trapped under the vehicle head restraint. If this happens, adjust the head restraint. See Head Restraints 0 46. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 70 Seats and Restraints 6. Restart the vehicle. The passenger sensing system may or may not turn off the airbag for a child in a child restraint depending upon the child’s size. It is better to secure child restraints in the rear seat. Consider using another vehicle to transport the child when a rear seat is not available. Never put a rear-facing child restraint in the front seat, even if the ON indicator is not lit. If the Off Indicator Is Lit for an Adult-Sized Occupant If a person of adult size is sitting in the front outboard passenger seat, but the OFF indicator is lit, it could be because that person is not sitting properly in the seat or that the child restraint locking feature is engaged. Use the following steps to allow the system to detect that person and enable the front outboard passenger frontal airbag: 1. Turn the vehicle off. 2. Remove any additional material from the seat, such as blankets, cushions, seat covers, seat heaters, or seat massagers. 3. Place the seatback in the fully upright position. 4. Have the person sit upright in the seat, centered on the seat cushion, with legs comfortably extended. 5. If the shoulder portion of the belt is pulled out all the way, the child restraint locking feature will be engaged. This may unintentionally cause the passenger sensing system to turn the airbag off for some adult-sized occupants. If this happens, unbuckle the belt, let the belt go back all the way, and then buckle the belt again without pulling the belt out all the way. 6. Restart the vehicle and have the person remain in this position for two to three minutes after the ON indicator is lit. { Warning If the front outboard passenger airbag is turned off for an adult-sized occupant, the airbag will not be able to inflate and help protect that person in a crash, resulting in an increased risk of serious injury or even death. An adult-sized occupant should not ride in the front outboard passenger seat, if the passenger airbag OFF indicator is lit. Additional Factors Affecting System Operation Seat belts help keep the passenger in position on the seat during vehicle maneuvers and braking, which helps the passenger sensing system maintain the passenger airbag status. See “Seat Belts” and “Child Restraints” in the Index for additional information about the importance of proper restraint use. A thick layer of additional material, such as a blanket or cushion, or aftermarket equipment such as seat covers, seat heaters, and seat massagers can affect how well the passenger sensing system operates. We recommend that you not use seat covers or other aftermarket equipment except when Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Seats and Restraints approved by GM for your specific vehicle. See Adding Equipment to the Airbag-Equipped Vehicle 0 71 for more information about modifications that can affect how the system operates. The ON indicator may be lit if an object, such as a briefcase, handbag, grocery bag, laptop, or other electronic device, is put on an unoccupied seat. If this is not desired, remove the object from the seat. { Warning Stowing articles under the passenger seat or between the passenger seat cushion and seatback may interfere with the proper operation of the passenger sensing system. Servicing the Airbag-Equipped Vehicle Airbags affect how the vehicle should be serviced. There are parts of the airbag system in several places around the vehicle. Your dealer and the service manual have information about servicing the vehicle and the airbag system. To purchase a service manual, see Publication Ordering Information 0 416. { Warning For up to 10 seconds after the vehicle is turned off and the battery is disconnected, an airbag can still inflate during improper service. You can be injured if you are close to an airbag when it inflates. Avoid yellow connectors. They are probably part of the airbag system. Be sure to follow proper service procedures, and make sure the person performing work for you is qualified to do so. Adding Equipment to the Airbag-Equipped Vehicle Adding accessories that change the vehicle's frame, bumper system, height, front end, or side sheet metal, may keep the airbag system from working properly. The operation of the airbag system can also be affected by changing, including improperly repairing or replacing, any parts of the following: . Airbag system, including airbag modules, front or side impact sensors, sensing and diagnostic module, or airbag wiring 71 . Front seats, including stitching, seams, or zippers . Seat belts . Steering wheel, instrument panel, overhead console, ceiling trim, or pillar garnish trim . Inner door seals, including speakers Your dealer and the service manual have information about the location of the airbag modules and sensors, sensing and diagnostic module, and airbag wiring along with the proper replacement procedures. In addition, the vehicle has a passenger sensing system for the front outboard passenger position, which includes sensors that are part of the passenger seat. The passenger sensing system may not operate properly if the original seat trim is replaced with non-GM covers, upholstery, or trim; or with GM covers, upholstery, or trim designed for a different vehicle. Any object, such as an aftermarket seat heater or a comfort-enhancing pad or device, installed under or on top of the seat fabric, could also interfere with the operation of the passenger sensing system. This could either prevent proper deployment of the passenger airbag(s) or prevent the passenger sensing Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 72 Seats and Restraints system from properly turning off the passenger airbag(s). See Passenger Sensing System 0 67. If the vehicle has rollover roof-rail airbags, see Different Size Tires and Wheels 0 360 for additional important information. If a snow plow is added to the vehicle, the airbags should still work properly. The airbag systems were designed to work properly under a wide range of conditions, including snow plowing with vehicles that have the optional snow plow prep package (RPO VYU). Do not change or defeat the snow plow's “tripping mechanism.” If you do, it can damage the snow plow and the vehicle, and may cause an airbag deployment. If the vehicle must be modified because you have a disability and have questions about whether the modifications will affect the vehicle's airbag system, or if you have questions about whether the airbag system will be affected if the vehicle is modified for any other reason, call Customer Assistance. See Customer Assistance Offices 0 411. Airbag System Check The airbag system does not need regularly scheduled maintenance or replacement. Make sure the airbag readiness light is working. See Airbag Readiness Light 0 114. Caution If an airbag covering is damaged, opened, or broken, the airbag may not work properly. Do not open or break the airbag coverings. If there are any opened or broken airbag coverings, have the airbag covering and/or airbag module replaced. For the location of the airbags, see Where Are the Airbags? 0 64. See your dealer for service. Replacing Airbag System Parts after a Crash { Warning A crash can damage the airbag systems in the vehicle. A damaged airbag system may not properly protect you and your passenger(s) in a crash, resulting in serious injury or even death. To help (Continued) Warning (Continued) make sure the airbag systems are working properly after a crash, have them inspected and any necessary replacements made as soon as possible. If an airbag inflates, you will need to replace airbag system parts. See your dealer for service.

Does the lap belt fit low and snug on the hips, touching the thighs? If yes, continue. If no, return to the booster seat. . Can proper seat belt fit be maintained for the length of the trip? If yes, continue. If no, return to the booster seat. Q: What is the proper way to wear seat belts? Older children who have outgrown booster seats should wear the vehicle’s seat belts. The manufacturer instructions that come with the booster seat state the weight and height limitations for that booster. Use a booster seat with a lap-shoulder belt until the child passes the fit test below: . Sit all the way back on the seat. Do the knees bend at the seat edge? If yes, continue. If no, return to the booster seat. . Buckle the lap-shoulder belt. Does the shoulder belt rest on the shoulder? If yes, continue. If no, try using the rear seat A: An older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck. The lap belt should fit snugly below the hips, just touching the top of the thighs. This applies belt force to the child's pelvic bones in a crash. It should never be worn over the abdomen, which could cause severe or even fatal internal injuries in a crash. Also see “Rear Seat Belt Comfort Guides” under Lap-Shoulder Belt 0 58. 73 According to accident statistics, children are safer when properly restrained in a rear seating position. In a crash, children who are not buckled up can strike other people who are buckled up, or can be thrown out of the vehicle. Older children need to use seat belts properly. { Warning Never allow more than one child to wear the same seat belt. The seat belt cannot properly spread the impact forces. In a crash, they can be crushed together and seriously injured. A seat belt must be used by only one person at a time. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 74 Seats and Restraints { Warning Warning (Continued) Never allow a child to wear the seat belt shoulder belt under both arms or behind their back. A child can be seriously injured by not wearing the lap-shoulder belt properly. In a crash, the child would not be restrained by the shoulder belt. The child could move too far forward increasing the chance of head and neck injury. The child might also slide under the lap belt. The belt force would then be applied right on the abdomen. That could cause serious or fatal injuries. The shoulder belt should go over the shoulder and across the chest. their neck. The shoulder belt can tighten but cannot be loosened if it is locked. The shoulder belt locks when it is pulled all the way out of the retractor. It unlocks when the shoulder belt is allowed to go all the way back into the retractor, but it cannot do this if it is wrapped around the child. Never leave children unattended in a vehicle and never allow children to improperly wear, or play with, the seat belts. Infants and Young Children Everyone in a vehicle needs protection! This includes infants and all other children. Neither the distance traveled nor the age and size of the traveler changes the need, for everyone, to use safety restraints. In fact, the law in every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle. { Warning Children can be seriously injured or killed if the shoulder belt is worn behind their back, under their legs, or wrapped around (Continued) Every time infants and young children ride in vehicles, they should have the protection provided by appropriate child restraints. Neither the vehicle's seat belt system nor its airbag system is designed for them. Children who are not restrained properly can strike other people, or can be thrown out of the vehicle. { Warning Never hold an infant or a child while riding in a vehicle. Due to crash forces, an infant or a child will become so heavy it (Continued) Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

For example, in a crash at only 40 km/h (25 mph), a 5.5 kg (12 lb) infant will suddenly become a 110 kg (240 lb) force on a person's arms. An infant or child should be secured in an appropriate child restraint. outboard seat. Secure a rear-facing child restraint in a rear seat. It is also better to secure a forward-facing child restraint in a rear seat. If you must secure a forward-facing child restraint in the front outboard seat, always move the front passenger seat as far back as it will go. { Warning Child restraints are devices used to restrain, seat, or position children in the vehicle and are sometimes called child seats or car seats. Children who are up against, or very close to, any airbag when it inflates can be seriously injured or killed. Never put a rear-facing child restraint in the front (Continued) There are three basic types of child restraints: . Forward-facing child restraints 75 . Rear-facing child restraints . Belt-positioning booster seats The proper child restraint for your child depends on their size, weight, and age, and also on whether the child restraint is compatible with the vehicle in which it will be used. For each types of child restraints, there are many different models available. When purchasing a child restraint, be sure it is designed to be used in a motor vehicle and is certified to comply with US Federal or Canadian Motor Vehicle Safety Standards. If it is, the child restraint will have a label saying that it meets federal motor vehicle safety standards. The NHTSA website includes a list of registered car seat manufacturers (https://www.nhtsa.gov) and links to their registration pages for consumers. Registration helps manufacturers identify purchasers for recall notices. The instruction manual that is provided with the child restraint states the weight and height limitations for that particular child restraint. In addition, there are many kinds of child restraints available for children with special needs. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 76 Seats and Restraints { Warning Child Restraint Systems To reduce the risk of neck and head injury in a crash, infants and toddlers should be secured in a rear-facing child restraint until age two, or until they reach the maximum height and weight limits of their child restraint. { Warning A young child's hip bones are still so small that the vehicle seat belt may not remain low on the hip bones, as it should. Instead, it may settle up around the child's abdomen. In a crash, the belt would apply force on a body area that is unprotected by any bony structure. This alone could cause serious or fatal injuries. To reduce the risk of serious or fatal injuries during a crash, young children should always be secured in an appropriate child restraint. Forward-Facing Child Restraint Rear-Facing Infant Restraint A rear-facing child restraint provides restraint with the seating surface against the back of the infant. The harness system holds the infant in place and, in a crash, acts to keep the infant positioned in the restraint. A forward-facing child restraint provides restraint for the child's body with the harness. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Seats and Restraints Securing an Add-On Child Restraint in the Vehicle { Warning Booster Seats A belt-positioning booster seat is used for children who have outgrown their forward-facing child restraint. Boosters are designed to improve the fit of the vehicle's seat belt system until the child is large enough for the vehicle seat belts to fit properly without a booster seat. See the seat belt fit test in Older Children 0 73. A child can be seriously injured or killed in a crash if the child restraint is not properly secured in the vehicle. Secure the child restraint properly in the vehicle using the vehicle seat belt or LATCH system, following the instructions that came with that child restraint and the instructions in this manual. To help reduce the chance of injury, the child restraint must be secured in the vehicle. Child restraints must be secured in vehicle seats by lap belts or the lap belt portion of a lap-shoulder belt, or by the LATCH system. See Lower Anchors and Tethers for Children (LATCH System) 0 79 for more information. Never use a seat belt extender when installing a child restraint. Use only seats and related equipment that are certified to comply with US Federal or Canadian Motor Vehicle Safety Standards to secure a child restraint. Children can be endangered in a crash if the child restraint is not properly secured in the vehicle. 77 When securing an add-on child restraint, refer to the following: 1. Instruction labels provided on the child restraint 2. Instruction manual provided with the child restraint 3. This vehicle owner's manual The child restraint instructions are important, so if they are not available, obtain a replacement copy from the manufacturer. Keep in mind that an unsecured child restraint can move around in a collision or sudden stop and injure people in the vehicle. Be sure to properly secure any child restraint in the vehicle — even when no child is in it. In some areas Certified Child Passenger Safety Technicians (CPSTs) are available to inspect and demonstrate how to correctly use and install child restraints. In the U.S., refer to the National Highway Traffic Safety Administration (NHTSA) website to locate the nearest child safety seat inspection station. For CPST availability in Canada, check with Transport Canada or the Provincial Ministry of Transportation office. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 78 Seats and Restraints Securing the Child Within the Child Restraint { Warning A child can be seriously injured or killed in a crash if the child is not properly secured in the child restraint. Secure the child properly following the instructions that came with that child restraint. Where to Put the Restraint According to accident statistics, children and infants are safer when properly restrained in an appropriate child restraint secured in a rear seating position. Whenever possible, children aged 12 and under should be secured in a rear seating position. Never put a rear-facing child restraint in the front. This is because the risk to the rear-facing child is so great if the airbag deploys. { Warning A child in a rear-facing child restraint can be seriously injured or killed if the front passenger airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag. A child in a forward-facing child restraint can be seriously injured or killed if the front passenger airbag inflates and the passenger seat is in a forward position. Even if the passenger sensing system has turned off the front passenger frontal airbag, no system is fail-safe. No one can guarantee that an airbag will not deploy under some unusual circumstance, even though it is turned off. Secure rear-facing child restraints in a rear seat, even if the airbag is off. If you secure a forward-facing child restraint in the front seat, always move the front passenger seat as far back as it will go. It is better to secure the child restraint in a rear seat. See Passenger Sensing System 0 67 for additional information. { Warning A child in a child restraint in the center front seat can be badly injured or killed by the frontal airbags if they inflate. Never secure a child restraint in the center front seat. It is always better to secure a child restraint in a rear seat. Do not use child restraints in the center front seat position. If the vehicle does not have a rear seat that will accommodate a rear-facing child restraint, a rear-facing child restraint should not be installed in the vehicle, even if the airbag is off. When securing a child restraint with the seat belts in a rear seat position, study the instructions that came with the child restraint to make sure it is compatible with this vehicle. Child restraints and booster seats vary considerably in size, and some may fit in certain seating positions better than others. Do not install a child restraint in any rear seating position where it cannot be installed securely. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Seats and Restraints Depending on where you place the child restraint and the size of the child restraint, you may not be able to access adjacent seat belts or LATCH anchors for additional passengers or child restraints. Adjacent seating positions should not be used if the child restraint prevents access to or interferes with the routing of the seat belt. The seat in front of an installed child restraint should be adjusted to ensure proper installation according to the child restraint manual. Wherever a child restraint is installed, be sure to follow the instructions that came with the child restraint and secure the child restraint properly. Keep in mind that an unsecured child restraint can move around in a collision or sudden stop and injure people in the vehicle. Be sure to properly secure any child restraint in the vehicle — even when no child is in it. 79 Lower Anchors and Tethers for Children (LATCH System) Make sure to follow the instructions that came with the child restraint, and also the instructions in this manual. The LATCH system secures a child restraint during driving or in a crash. LATCH attachments on the child restraint are used to attach the child restraint to the anchors in the vehicle. This system is designed to make installation of a child restraint easier. When installing a child restraint with a top tether, you must also use either the lower anchors or the seat belts to properly secure the child restraint. A child restraint must never be installed using only the top tether. In order to use the LATCH system in your vehicle, you need a child restraint that has LATCH attachments. LATCH-compatible rear-facing and forward-facing child seats can be properly installed using either the LATCH anchors or the vehicle’s seat belts. Do not use both the seat belts and the LATCH anchorage system to secure a rear-facing or forward-facing child restraint. Booster seats use the vehicle’s seat belts to secure the child and the booster seat. If the manufacturer recommends that the booster seat be secured with the LATCH system, this can be done as long as the booster seat can be positioned properly and there is no interference with the proper positioning of the lap-shoulder belt on the child.

Follow the instructions that came with the child restraint and the instructions in this manual. { Warning Do not attach more than one child restraint to a single anchor, except for the center top tether anchors in the crew cab models. Attaching more than one child restraint to a single anchor could cause the anchor or attachment to come loose or even break during a crash. (Continued) Warning (Continued) Warning (Continued) A child or others could be injured. To reduce the risk of serious or fatal injuries during a crash, attach only one child restraint per anchor. tighten the belt behind the child restraint after the child restraint has been installed. Caution { Warning Children can be seriously injured or strangled if a shoulder belt is wrapped around their neck. The shoulder belt can tighten but cannot be loosened if it is locked. The shoulder belt locks when it is pulled all the way out of the retractor. It unlocks when the shoulder belt is allowed to go all the way back into the retractor, but it cannot do this if it is wrapped around a child’s neck. If the shoulder belt is locked and tightened around a child’s neck, the only way to loosen the belt is to cut it. Buckle any unused seat belts behind the child restraint so children cannot reach them. Pull the shoulder belt all the way out of the retractor to set the lock, and (Continued) Do not let the LATCH attachments rub against the vehicle’s seat belts. This may damage these parts. If necessary, move buckled seat belts to avoid rubbing the LATCH attachments. Do not fold the rear seat cushion when the seat is occupied. Do not fold the empty rear seat with a seat belt buckled. This could damage the seat belt or the seat. Unbuckle and return the seat belt to its stowed position, before folding the seat.

S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 146 Lighting Reading Lamps All lamps will gradually fade out after about 30 seconds. There are reading lamps on the overhead console and over the rear seats. These lamps come on when any door is opened, K on the Remote Keyless Entry (RKE) Transmitter is pressed, or when the vehicle is turned off. To operate, the vehicle must be on, or in Accessory mode, or using Retained Accessory Power (RAP). Entry lighting can be disabled manually by closing all doors, pressing Q on the RKE transmitter, or starting the vehicle. This feature can be changed. See “Vehicle Locator Lights” under Vehicle Personalization 0 131. Rear Reading Lamps The rear reading lamps are over the rear seats. Press the lamp lens to turn the rear reading lamps on or off.

S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Lighting Battery Load Management The vehicle has Electric Power Management (EPM), which estimates the battery's temperature and state of charge. It then adjusts the voltage for best performance and extended life of the battery. When the battery's state of charge is low, the voltage is raised slightly to quickly bring the charge back up. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. The voltmeter gauge or the voltage display on the Driver Information Center (DIC), if equipped, may show the voltage moving up or down. This is normal. If there is a problem, an alert will be displayed. The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles. This is because the generator (alternator) may not be spinning fast enough at idle to produce all the power that is needed for very high electrical loads. A high electrical load occurs when several of the following are on, such as: headlamps, high beams, fog lamps, rear window defogger, climate control fan at high speed, 147 heated seats, engine cooling fans, trailer loads, and loads plugged into accessory power outlets. . The doors are closed and then re-opened. EPM works to prevent excessive discharge of the battery. It does this by balancing the generator's output and the vehicle's electrical needs. It can increase engine idle speed to generate more power, whenever needed. It can temporarily reduce the power demands of some accessories. The exterior lamps turn off about 10 minutes after the ignition is turned off, if the parking lamps or headlamps have been manually left on. This protects against draining the battery. To restart the 10-minute timer, turn the exterior lamp control to the O position and then back to the ; or 2 position. Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest levels of corrective action, this action may be noticeable to the driver. If so, a DIC message might be displayed and it is recommended that the driver reduce the electrical loads as much as possible. To keep the lamps on for more than 10 minutes, the ignition must be on or in ACC/ACCESSORY. Battery Power Protection This feature helps prevent the battery from being drained, if the interior courtesy lamps or reading lamps are accidentally left on. If any of these lamps are left on, they automatically turn off after 10 minutes, if the ignition is off. The lamps will not come back on again until one of the following occurs: . The ignition is turned on. Exterior Lighting Battery Saver Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

FM FM signals only reach about 16 to 65 km (10 to 40 mi). Although the radio has a built-in electronic circuit that automatically works to reduce interference, some static can occur, especially around tall buildings or hills, causing the sound to fade in and out. AM The range for most AM stations is greater than for FM, especially at night. The longer range can cause station frequencies to interfere with each other. Static can also occur when things like storms and power lines interfere with radio reception. When this happens, try reducing the treble on the radio. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 158 Infotainment System SiriusXM Satellite Radio Service Multi-Band Antenna If equipped, SiriusXM Satellite Radio Service provides digital radio reception. Tall buildings or hills can interfere with satellite radio signals, causing the sound to fade in and out. In addition, traveling or standing under heavy foliage, bridges, garages, or tunnels may cause loss of the SiriusXM signal for a period of time. Some cellular services may interfere with SXM reception causing loss of signal. The roof antenna is for SiriusXM Satellite Radio, OnStar, and GPS (Global Positioning System), depending on the equipped options. Keep clear of obstructions for clear reception. If the vehicle has a sunroof, and it is open, reception can also be affected. Mobile Device Usage Mobile device usage, such as making or receiving calls, charging, or just having the mobile device on may cause static interference in the radio. Unplug the mobile device or turn it off if this happens. When using media devices such as SD cards, USB devices, and mobile devices, consider the source. Untrusted media devices could contain files that affect system operation or performance. Avoid use if the content or origin cannot be trusted.

Global Positioning System (GPS) If equipped, the position of the vehicle is determined by using satellite signals, various vehicle signals, and map data. At times, other interference such as the satellite condition, road configuration, condition of the vehicle, and/or other circumstances can affect the navigation system's ability to determine the accurate position of the vehicle. The GPS shows the current position of the vehicle using signals sent by GPS satellites. When the vehicle is not receiving signals from the satellites, a symbol appears in the status bar. This system might not be available or interference can occur if any of the following are true: . Signals are obstructed by tall buildings, trees, large trucks, or a tunnel. . Satellites are being repaired or improved. For more information if the GPS is not functioning properly, see Problems with Route Guidance 0 172 and If the System Needs Service 0 173. Vehicle Positioning At times, the position of the vehicle on the map could be inaccurate due to one or more of the following reasons: . The road system has changed. . The vehicle is driving on slippery road surfaces such as sand, gravel, or snow. . The vehicle is traveling on winding roads or long, straight roads. . The vehicle is approaching a tall building or a large vehicle. . The surface streets run parallel to a freeway. . The vehicle has been transferred by a vehicle carrier or a ferry. . The current position calibration is set incorrectly. . The vehicle is traveling at high speed. . The vehicle changes directions more than once, or the vehicle is turning on a turn table in a parking lot. . The vehicle is entering and/or exiting a parking lot, garage, or a lot with a roof. . . . . . . The GPS signal is not received. A roof carrier is installed on the vehicle. Tire chains are installed on the vehicle. The tires are replaced or worn. The tire pressure for the tires is incorrect. This is the first navigation use after the map data is updated. . The 12-volt battery has been disconnected for several days. . The vehicle is driving in heavy traffic where driving is at low speeds, and the vehicle is stopped and started repeatedly. Problems with Route Guidance Inappropriate route guidance can occur under one or more of the following conditions: . The turn was not made on the road indicated. . Route guidance might not be available when using automatic rerouting for the next right or left turn. . The route might not be changed when using automatic rerouting. . There is no route guidance when turning at an intersection. . Plural names of places might be announced occasionally. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

Automatic rerouting might display a route returning to the set waypoint if heading for a destination without passing through a set waypoint. The route prohibits the entry of a vehicle due to a regulation by time or season or any other regulation which may be given. Some routes might not be searched. The route to the destination might not be shown if there are new roads, if roads have recently changed, or if certain roads are not listed in the map data. See Maps 0 165. To recalibrate the vehicle's position on the map, park with the vehicle running for two to five minutes, until the vehicle position updates. Make sure the vehicle is parked in a location that is safe and has a clear view of the sky and away from large obstructions. If the System Needs Service If the navigation system needs service, see your dealer. Map Data Updates The map data in the vehicle is the most up-to-date information available when the vehicle was produced. The map data is updated periodically, provided that the map information has changed and the vehicle has a relevant service plan. See www.gmnavdisc.com for details on ordering, purchasing, and installing a new or replacement SD card. Features are subject to change. For more information on this feature, see my.chevrolet.com/learn. If the vehicle is equipped with Connected Navigation, which is a subscription service that enables certain features of the navigation system, such as Traffic, Smart Search/Routing, and Predictive Navigation, then the system will download the latest map data from the cloud. Database Coverage Explanations Coverage areas vary with respect to the level of map detail available for any given area. Some areas feature greater levels of detail than others. If this happens, it does not mean there is a problem with the system. As the map data is updated, more 173 detail can become available for areas that previously had limited detail. See Map Data Updates 0 173. Voice Recognition If equipped, voice recognition allows for hands-free operation within the navigation, audio, phone, and weather applications. This feature can be started by pressing g on the steering wheel or touching g on the infotainment display. However, not all features within these areas are supported by voice commands. Generally, only complex tasks that require multiple manual interactions to complete are supported by voice commands. For example, tasks that take more than one or two touches, such as a song or artist to play from a media device, would be supported by voice commands. Other tasks, like adjusting the volume or seeking up or down, are audio features that are easily performed by touching one or two options, and are not supported by voice commands. In general there are flexible ways to speak commands for completing the tasks. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 174 Infotainment System If your language supports it, try stating a one-shot command, such as “Directions to address .” Do not include the ZIP code while stating the address during the command. Another example of a one-shot Destination Entry command is, “Directions to Place of Interest at .” If these commands do not work, try saying, “Take me to Place of Interest” or “Find address” and the system will walk you through by asking additional questions. Hybrid Speech Recognition If equipped, this feature helps distinguish words by using Internet-based information along with the system’s voice recognition database. This allows you to speak more naturally when using voice recognition. Using Voice Recognition Voice recognition becomes available once the system has been initialized. This begins when the ignition is turned on. Initialization may take a few moments. 1. Press g on the steering wheel controls to activate voice recognition. 2. The audio system mutes and the system plays a prompt. 3. Clearly speak one of the commands described in this section. A voice recognition system prompt can be interrupted while it is playing by pressing g again. Once voice recognition is started, both the infotainment display and instrument cluster show the selections and visual dialog content. These displays can be turned on or off in the Tutorial Mode under Settings 0 184. There are three voice prompt modes supported: . Informative verbal prompts: This type of prompt will provide more information regarding the supported actions. . Short prompts: This type of prompt will provide simple instructions about what can be stated. . Auto informative prompts: This type of prompt plays during the first few speech sessions, then automatically switches to the short prompt after some experience has been gained through using the system. If a command is not spoken, the voice recognition system says a help prompt. Prompts and Infotainment Displays While a voice recognition session is active, there may be corresponding options showing on the displays. A selection can be made by manually touching the option, or by speaking the number for the option to select. Manual interaction in the voice recognition session is permitted. Interaction during a voice session may be completed entirely using voice commands while some manual commands may expedite a task. If a selection is made using a manual control, the voice recognition dialog will progress in the same way as if the selection were made using a voice command. Once the system completes the task, or the session is terminated, the voice recognition dialog stops. An example of this type of manual intervention is touching an entry of a displayed number list instead of speaking the number associated with the entry desired. Canceling Voice Recognition . Touch or say “Cancel” or “Exit” to terminate the voice recognition session and show the display where voice recognition was initiated. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Infotainment System i on the steering wheel controls to terminate the voice recognition session and show the display where voice recognition was initiated. . Press Natural Language Commands Most languages do not support natural language commands in sentence form. For those languages, use direct commands like the examples shown on the display. Helpful Hints for Speaking Commands Voice recognition can understand commands that are naturally stated in sentence form or direct commands that state the application and the task. For best results: . Listen for the prompt before saying a command or reply. . Speak the command naturally, not too fast, not too slow. . Use direct commands without a lot of extra words. For example, “Call at work,” “Play” followed by the artist or song name, or “Tune” followed by the radio station number. . Navigation destinations can be made in a single command using keywords. A few examples are: “I want directions to an address,” “I need to find a place of interest or (POI),” or “Find contact.” The system responds by requesting more details. For other POIs, say the name of a category like “Restaurants,” “Shopping Malls,” or “Hospitals.” . Navigating to a destination outside of the current country takes more than one command. The first command is to tell the system where the navigation will take place, such as an Address, Intersection, POI, or Contact. If Address or Intersection is selected, the second command is to say, “Change Country.” Once the system responds, say the country before saying the rest of the address and/or intersection. If POI is asked for, say “Change Location,” then “Change Country.” Direct commands might be more clearly understood by the system. An example of a direct command would be “Call .” Examples of these direct commands are displayed on most of the screens while a voice session is active. If “Phone” or “Phone Commands,” is spoken, the system 175 understands that a phone call is requested and will respond with questions until enough details are gathered to make a call. If a cell phone number has been saved with a name and a place, the direct command should include both, for example “Call at work.” Using Voice Recognition for List Options When a list is displayed, a voice prompt will ask to confirm or select an option from that list. When a display contains a list, there may be options that are available but not displayed. The list on a voice recognition screen functions the same as a list on other displays. Scrolling or flinging can be used to help display other entries from the list. Manually scrolling or paging the list on a display during a voice recognition session suspends the current voice recognition event and plays the prompt “Please select manually or touch the Back icon on the infotainment display to try again.” Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 176 Infotainment System If manual selection takes more than 15 seconds, the session terminates and prompts that it has timed out. The display returns to the display where voice recognition was initiated. “Switch to SXM” : Switch bands to SiriusXM and tune to the last SiriusXM channel. The Back Command “Tune to FM” : Tune to the radio station whose frequency is identified in the command (like “one oh one point one”). Say “Back” or touch the Back icon on the infotainment display to go to the previous menu. If in voice recognition, and “Back” is spoken all the way back to the starting display, and then “Back” is spoken one more time, the voice recognition session will cancel. Help Say “Help” on any voice recognition display and the help prompt for the display is played. “Tune to AM” : Tune to the radio station whose frequency is identified in the command (like “nine fifty”). “Tune to AM HD” : Tune to the HD Radio station (if equipped) whose frequency is identified in the command. “Tune to FM HD” : Tune to the HD Radio station (if equipped) whose frequency is identified in the command. Voice Recognition for the Radio “Tune to FM HD ” : Tune to the HD Radio station (if equipped) whose frequency and HD channel are identified in the command. If browsing the audio sources when voice is touched, the voice recognition commands for AM, FM, and SiriusXM (if equipped) are available. “Tune to SXM ” : Tune to the SiriusXM radio station whose channel number is identified in the command. “Switch to AM” : Switch bands to AM and tune to the last AM radio station. “Tune to SXM ” : Tune to the SiriusXM radio station whose channel name is identified in the command. “Switch to FM” : Switch bands to FM and tune to the last FM radio station. Voice Recognition for Audio MyMedia The available voice recognition commands for [browsing] MyMedia are: “Play Artist” : Begin a dialog to enter a specific artist name. “Play Artist ” : Begin playback of a specific artist. “Play Album” : Begin a dialog to enter a specific album name. “Play Album ” : Begin playback of a specific album. “Play Song” : Begin a dialog to enter a specific song name. “Play Song ” : Begin playback of a specific song, if available. “Play Genre” : Begin a dialog to enter a specific genre. “Play Genre ” : Begin playback of a specific genre. “Play Playlist” : Begin a dialog to enter a specific playlist name. “Play Playlist ” : Begin playback of a specific playlist. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Infotainment System “Play ” : Play music from a specific device identified by name. The device name is the name displayed on the display when the device is first selected as an audio source. “Play Chapter” : Begin a dialog to enter a specific name. “Play Chapter ” : Begin playback of a specific chapter. “Play Audiobook” : Begin a dialog to enter a specific audiobook. “Play Audiobook ” : Begin playback of a specific audiobook. “Play Episode” : Begin a dialog to enter a specific name. “Play Episode ” : Begin playback of a specific episode. “Play Podcast” : Begin a dialog to enter a specific podcast. “Play Podcast ” : Begin playback of a specific podcast. “My Media” : Begin a dialog to enter the desired media content. Handling Large Amounts of Media Content It is expected that large amounts of media content will be brought into the vehicle. It may be necessary to handle large amounts of media content in a different way than smaller amounts of media. The system may limit the options of voice recognition by not allowing selection of files by voice at the highest level if the number of files exceeds the maximum limit. Changes to voice commands due to media content limits are: . Files including other individual files of all media types such as songs, audiobook chapters, podcast episodes, and videos. . Album type folders including types such as albums and audiobooks. There are no restrictions if the number of files and albums is fewer than 12,000. When the number of files connected to the system is between 12,000 and 24,000, the content cannot be accessed directly with one command like “Play .” The restriction is that the command “Play Song” must be spoken first; the system will then ask for the song name. The reply command would be to say the name of the song to play. 177 Similar limits exist for album content. If there are more than 12,000 albums, but fewer than 24,000, the content cannot be accessed directly with one command like, “Play .” The command “Play Album” must first be spoken; the system will then ask for the album name. The reply would be to say the name of the album to play. Once the number of files has exceeded approximately 24,000, there is no support for accessing the songs directly through voice commands. There will still be access to the media content by using commands for playlists, artists, and genres. The access commands for playlists, artists, and genres are prohibited after the number of this type of media exceeds 12,000. The system will provide feedback the first time voice recognition is initiated if it has become apparent that any of these limits are reached during a device initializing process. Voice recognition performance will degrade to some extent based on many factors when adding large amounts of data to recognize. If this is the case, perhaps accessing songs through playlists or artist name would work better. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Climate Controls The solar sensor, on top of the instrument panel near the windshield, monitors the solar heat. The climate control system uses the sensor information to adjust the temperature, fan speed, recirculation, and air delivery mode for best comfort. Do not cover the sensor; otherwise the automatic climate control system may not work properly. Afterblow Feature If equipped, under certain conditions, the fan may stay on or may turn on and off several times after you turn off and lock the vehicle. This is normal. Air Vents Use the sliding knobs on the center and side air vents to change the direction of the airflow. Air vents blow warm air on the side windows in cold weather. If Floor, Defog, or Defrost modes are selected, a small amount of air will come from the vents close to the window. To close the front a/c vents, move the sliding knobs to the full down position. To close the rear a/c vents, move the sliding knobs to the full inboard position. Operation Tips . Clear away any ice, snow, or leaves from air inlets at the base of the windshield that could block the flow of air into the vehicle. . Clear snow off the hood to improve visibility and help decrease moisture drawn into the vehicle. . Keep the path under the front seats clear of objects to help circulate the air inside of the vehicle more effectively. . Use of non-GM approved hood deflectors can adversely affect the performance of the system. Check with your dealer before adding equipment to the outside of the vehicle. . Do not attach any devices to the air vent slats. This will restrict airflow and may cause damage to the air vents. Maintenance Passenger Compartment Air Filter The filter reduces the dust, pollen, and other airborne irritants from outside air that is pulled into the vehicle. 207 The filter should be replaced as part of routine scheduled maintenance. See Maintenance Schedule 0 392. To find out what type of filter to use, see Maintenance Replacement Parts 0 402. 1.

Reverse the steps to reinstall the glove box. See your dealer if additional assistance is needed. Service All vehicles have a label underhood that identifies the refrigerant used in the vehicle. The refrigerant system should only be serviced by trained and certified technicians. The air conditioning evaporator should never be repaired or replaced by one from a salvage vehicle. It should only be replaced by a new evaporator to ensure proper and safe operation. During service, all refrigerants should be reclaimed with proper equipment. Venting refrigerants directly to the atmosphere is harmful to the environment and may also create unsafe conditions based on inhalation, combustion, frostbite, or other health-based concerns. The air conditioning system requires periodic maintenance. See Maintenance Schedule 0 392. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

Exercise good judgment and do not let other activities divert your attention away from the road. Many local governments have enacted laws regarding driver distraction. Become familiar with the local laws in your area. Driving habits can affect fuel mileage. Here are some driving tips to get the best fuel economy possible: . Set the climate controls to the desired temperature after the engine is started, or turn them off when not required. . Avoid fast starts and accelerate smoothly. . Brake gradually and avoid abrupt stops. . Avoid idling the engine for long periods of time. . When road and weather conditions are appropriate, use cruise control. . Always follow posted speed limits or drive more slowly when conditions require. . Keep vehicle tires properly inflated. . Combine several trips into a single trip. . Replace the vehicle's tires with the same TPC Spec number molded into the tire's sidewall near the size. . Follow recommended scheduled maintenance. To avoid distracted driving, keep your eyes on the road, keep your hands on the steering wheel, and focus your attention on driving. . Do not use a phone in demanding driving situations. Use a hands-free method to place or receive necessary phone calls. . Watch the road. Do not read, take notes, or look up information on phones or other electronic devices. . Designate a front seat passenger to handle potential distractions. . Become familiar with vehicle features before driving, such as programming favorite radio stations and adjusting climate control and seat settings. Program all trip information into any navigation device prior to driving. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating . Wait until the vehicle is parked to . Assume that other road users retrieve items that have fallen to the floor. . Stop or park the vehicle to tend to children. . Keep pets in an appropriate carrier or restraint. . Avoid stressful conversations while driving, whether with a passenger or on a cell phone. (pedestrians, bicyclists, and other drivers) are going to be careless and make mistakes. Anticipate what they may do and be ready. . Allow enough following distance between you and the driver in front of you. . Focus on the task of driving. { Warning Taking your eyes off the road too long or too often could cause a crash resulting in injury or death. Focus your attention on driving. Refer to the infotainment section for more information on using that system and the navigation system, if equipped, including pairing and using a cell phone. Defensive Driving Defensive driving means “always expect the unexpected.” The first step in driving defensively is to wear the seat belt. See Seat Belts 0 55. Impaired Driving Death and injury associated with impaired driving is a global tragedy. { Warning Drinking alcohol or taking drugs and then driving is very dangerous. Your reflexes, perceptions, attentiveness, and judgment can be affected by even a small amount of alcohol or drugs. You can have a serious — or even fatal — collision if you drive after drinking or taking drugs. Do not drive while under the influence of alcohol or drugs, or ride with a driver who has been drinking or is impaired by drugs. Find alternate transportation home; or if you are with a group, designate a driver who will remain sober. 211 Control of a Vehicle Braking, steering, and accelerating are important factors in helping to control a vehicle while driving. Braking Braking action involves perception time and reaction time. Deciding to push the brake pedal is perception time. Actually doing it is reaction time. Average driver reaction time is about three-quarters of a second. In that time, a vehicle moving at 100 km/h (60 mph) travels 20 m (66 ft), which could be a lot of distance in an emergency. Helpful braking tips to keep in mind include: . Keep enough distance between you and the vehicle in front of you. . Avoid needless heavy braking. . Keep pace with traffic. If the engine ever stops or a brake fault occurs, the brakes may lose power assist. More effort will be required to stop the vehicle. It may take longer to stop. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 212 Driving and Operating Steering Caution To avoid damage to the steering system, do not drive over curbs, parking barriers, or similar objects at speeds greater than 3 km/h (1 mph). Use care when driving over other objects such as lane dividers and speed bumps. Damage caused by misuse of the vehicle is not covered by the vehicle warranty. Hydraulic Power Steering (2500/3500 Series) (2500/3500 Series – All Regular Cab, Double Cab/Crew Cab with Base Interior) The power steering system may require maintenance. See Power Steering Fluid 0 320. If power steering assist is lost because the engine stops or the system malfunctions, the vehicle can be steered but may require increased effort. See your dealer. (2500/3500 Series – Double Cab/Crew Cab with Uplevel Interior) The vehicle has a power steering system that varies the amount of effort required to steer the vehicle. Less steering effort is required at slower speeds. At faster speeds, the required steering effort increases. The system helps the steering wheel return to center at low speeds. Pressing the Tow/Haul mode button adjusts steering effort for driving conditions described in Tow/Haul Mode 0 240. The power steering system may require maintenance. See Power Steering Fluid 0 320. If power steering assist is lost because the engine stops or the system malfunctions, the vehicle can be steered but may require increased effort. See your dealer. { Warning Do not hold the brake pedal and press the accelerator pedal at the same time. Damage may occur to the power steering and power brake systems which could lead to reduced performance, up to and including loss of steering and brake assist. Caution Do not hold the steering wheel at full rotation for more than 15 seconds and/or at an elevated RPM. Damage may occur to the power steering system and there may be loss of power steering assist. Curve Tips . Take curves at a reasonable speed. . Reduce speed before entering a curve. . Maintain a reasonable steady speed through the curve. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating . Wait until the vehicle is out of the curve around a problem may be more effective than braking. . Holding both sides of the steering wheel allows you to turn 180 degrees without removing a hand. . Antilock Brake System (ABS) allows steering while braking. The vehicle's right wheels can drop off the edge of a road onto the shoulder while driving. Follow these tips: 1. Ease off the accelerator and then, if there is nothing in the way, steer the vehicle so that it straddles the edge of the pavement. 2. Turn the steering wheel about one-eighth of a turn, until the right front tire contacts the pavement edge. 3. Turn the steering wheel to go straight down the roadway. Off-Road Recovery Loss of Control before accelerating gently into the straightaway. Steering in Emergencies . There are some situations when steering Skidding There are three types of skids that correspond to the vehicle's three control systems: . Braking Skid — wheels are not rolling. . Steering or Cornering Skid — too much speed or steering in a curve causes tires to slip and lose cornering force. . Acceleration Skid — too much throttle causes the driving wheels to spin. 213 Defensive drivers avoid most skids by taking reasonable care suited to existing conditions, and by not overdriving those conditions. But skids are always possible. If the vehicle starts to slide, follow these suggestions: . Ease your foot off the accelerator pedal and steer the way you want the vehicle to go. The vehicle may straighten out. Be ready for a second skid if it occurs. . Slow down and adjust your driving according to weather conditions. Stopping distance can be longer and vehicle control can be affected when traction is reduced by water, snow, ice, gravel, or other material on the road. Learn to recognize warning clues — such as enough water, ice, or packed snow on the road to make a mirrored surface — and slow down when you have any doubt. . Try to avoid sudden steering, acceleration, or braking, including reducing vehicle speed by shifting to a lower gear. Any sudden changes could cause the tires to slide. Remember: Antilock brakes help avoid only the braking skid. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 214 Driving and Operating Off-Road Driving Four-wheel-drive vehicles can be used for off-road driving. Vehicles without four-wheel drive and vehicles not equipped with All Terrain (AT) or On-Off Road (OOR) tires must not be driven off-road except on a level, solid surface. For contact information about the original equipment tires, see the warranty manual. One of the best ways for successful off-road driving is to control the speed. { Warning When driving off-road, bouncing and quick changes in direction can easily throw you out of position. This could cause you to lose control and crash. You and your passengers should always wear seat belts. Before Driving Off-Road . Have all necessary maintenance and service work completed. . Fuel the vehicle, fill fluid levels, and check inflation pressure in all tires, including the spare, if equipped. . Read all the information about four-wheel-drive vehicles in this manual. . Remove any underbody air deflector, if equipped. Re-attach the air deflector after off-road driving. . Know the local laws that apply to off-road driving. To gain more ground clearance if needed, it may be necessary to remove the front fascia lower air dam, if equipped. However, driving without the air dam reduces fuel economy. Caution Warning (Continued) . Keep cargo in the cargo area as far forward and as low as possible. The heaviest things should be on the floor, forward of the rear axle. . Heavy loads on the roof raise the vehicle's center of gravity, making it more likely to roll over. You can be seriously or fatally injured if the vehicle rolls over. Put heavy loads inside the cargo area, not on the roof. Operating the vehicle for extended periods without the front fascia lower air dam installed can cause improper airflow to the engine. Reattach the front fascia air dam after off-road driving. For more information about loading the vehicle, see Vehicle Load Limits 0 220 and Tires 0 344. Loading the Vehicle for Off-Road Driving . Always use established trails, roads, and { Warning . Unsecured cargo on the load floor can be tossed about when driving over rough terrain. You or your passengers can be struck by flying objects. Secure the cargo properly. (Continued) Environmental Concerns areas that have been set aside for public off-road recreational driving and obey all posted regulations. . Do not damage shrubs, flowers, trees, or grasses or disturb wildlife. . Do not park over things that burn. See Parking over Things That Burn 0 234. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating Driving on Hills Driving safely on hills requires good judgment and an understanding of what the vehicle can and cannot do. { Warning Many hills are simply too steep for any vehicle. Driving up hills can cause the vehicle to stall. Driving down hills can cause loss of control. Driving across hills can cause a rollover. You could be injured or killed. Do not drive on steep hills. Before driving on a hill, assess the steepness, traction, and obstructions. If the terrain ahead cannot be seen, get out of the vehicle and walk the hill before driving further. When driving on hills: . Use a low gear and keep a firm grip on the steering wheel. . Maintain a slow speed. . When possible, drive straight up or down the hill. . Slow down when approaching the top of the hill. . Use headlamps even during the day to make the vehicle more visible. { Warning Driving to the top of a hill at high speed can cause a crash. There could be a drop-off, embankment, cliff, or even another vehicle. You could be seriously injured or killed. As you near the top of a hill, slow down and stay alert. . Never go downhill forward or backward with either the transmission or transfer case in N (Neutral). The brakes could overheat and you could lose control. { Warning If the vehicle has the two-speed automatic transfer case, shifting the transfer case to N (Neutral) can cause your vehicle to roll even if the transmission is in P (Park). This is because the N (Neutral) position on the transfer case overrides the transmission. You or someone else could be injured. If leaving the vehicle, set the parking brake and shift the transmission to P (Park). Shift the transfer case to any position but N (Neutral). 215 . When driving down a hill, keep the vehicle headed straight down. Use a low gear because the engine will work with the brakes to slow the vehicle and help keep the vehicle under control. { Warning Heavy braking when going down a hill can cause your brakes to overheat and fade. This could cause loss of control and you or others could be injured or killed. Apply the brakes lightly when descending a hill and use a low gear to keep vehicle speed under control. If a brake fade condition is detected, a DIC warning message is displayed. Adjust brake pedal use and shift to a lower transmission gear to reduce braking. If the brakes continue to fade to a severe condition, additional DIC messages are displayed. The brake system warning light will illuminate, and the vehicle speed may be limited. See Brake System Warning Light 0 117. If the vehicle stalls on a hill: 1. Apply the brakes to stop the vehicle, and then apply the parking brake. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 216 Driving and Operating 2. Shift into P (Park) and then restart the engine. . If driving uphill when the vehicle stalls, shift to R (Reverse), release the parking brake, and back straight down. . Never try to turn the vehicle around. If the hill is steep enough to stall the vehicle, it is steep enough to cause it to roll over. . If you cannot make it up the hill, back straight down the hill. . Never back down a hill in N (Neutral) using only the brake. The vehicle can roll backward quickly and you could lose control. . If driving downhill when the vehicle stalls, shift to a lower gear, release the parking brake, and drive straight down the hill. 3. If the vehicle cannot be restarted after stalling, set the parking brake, shift into P (Park), and turn the vehicle off. 3.1. Leave the vehicle and seek help. 3.2. Stay clear of the path the vehicle would take if it rolled downhill. . Avoid turns that take the vehicle across the incline of the hill. A hill that can be driven straight up or down might be too steep to drive across. Driving across an incline puts more weight on the downhill wheels, which could cause a downhill slide or a rollover. . Surface conditions can be a problem. Loose gravel, muddy spots, or even wet grass can cause the tires to slip sideways, downhill. If the vehicle slips sideways, it can hit something that will trip it — a rock, a rut, etc. — and roll over. . Hidden obstacles can make the steepness of the incline more severe. If a rock is driven across with the uphill wheels, or if the downhill wheels drop into a rut or depression, the vehicle can tilt even more. . If an incline must be driven across, and the vehicle starts to slide, turn downhill. This should help straighten out the vehicle and prevent the side slipping. { Warning Getting out of the vehicle on the downhill side when stopped across an incline is dangerous. If the vehicle rolls over, you could be crushed or killed. (Continued) Warning (Continued) Always get out on the uphill side of the vehicle and stay well clear of the rollover path. Driving in Mud, Sand, Snow, or Ice Use a low gear when driving in mud — the deeper the mud, the lower the gear. Keep the vehicle moving to avoid getting stuck. Traction changes when driving on sand. On loose sand, such as on beaches or sand dunes, the tires tend to sink into the sand. This affects steering, accelerating, and braking. Drive at a reduced speed and avoid sharp turns or abrupt maneuvers. Traction is reduced on hard packed snow and ice and it is easy to lose control. Reduce vehicle speed when driving on hard packed snow and ice. { Warning Driving on frozen lakes, ponds, or rivers can be dangerous. Ice conditions vary greatly and the vehicle could fall through (Continued) Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

Driving in Water under water. Do not turn off the ignition when driving through water. If the exhaust pipe is under water, the engine will not start. When going through water, the brakes get wet and it may take longer to stop. See “Driving on Wet Roads” later in this section. After Off-Road Driving { Warning Driving through rushing water can be dangerous. Deep water can sweep your vehicle downstream and you and your passengers could drown. If it is only shallow water, it can still wash away the ground from under your tires. Traction could be lost, and the vehicle could roll over. Do not drive through rushing water. Caution Do not drive through standing water if it is deep enough to cover the wheel hubs, axles, or exhaust pipe. Deep water can damage the axle and other vehicle parts. If the standing water is not too deep, drive through it slowly. At faster speeds, water can get into the engine and cause it to stall. Stalling can occur if the exhaust pipe is Remove any brush or debris that has collected on the underbody or chassis, or under the hood. These accumulations can be a fire hazard. Re-install underbody air deflector and air dam if removed. After operation in mud or sand, have the brake linings cleaned and checked. These substances can cause glazing and uneven braking. Check the body structure, driveline, steering, suspension, wheels, tires, and exhaust system for damage and check the fuel lines and cooling system for any leakage. More frequent maintenance service is required. See the Maintenance Schedule 0 392. Driving on Wet Roads Rain and wet roads can reduce vehicle traction and affect your ability to stop and accelerate. Always drive slower in these 217 types of driving conditions and avoid driving through large puddles and deep-standing or flowing water. { Warning Wet brakes can cause crashes. They might not work as well in a quick stop and could cause pulling to one side. You could lose control of the vehicle. After driving through a large puddle of water or a car/vehicle wash, lightly apply the brake pedal until the brakes work normally. Flowing or rushing water creates strong forces. Driving through flowing water could cause the vehicle to be carried away. If this happens, you and other vehicle occupants could drown. Do not ignore police warnings and be very cautious about trying to drive through flowing water. Hydroplaning Hydroplaning is dangerous. Water can build up under the vehicle's tires so they actually ride on the water. This can happen if the Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 218 Driving and Operating road is wet enough and you are going fast enough. When the vehicle is hydroplaning, it has little or no contact with the road. There is no hard and fast rule about hydroplaning. The best advice is to slow down when the road is wet. Other Rainy Weather Tips Besides slowing down, other wet weather driving tips include: . Allow extra following distance. . Pass with caution. . Keep windshield wiping equipment in good shape. . Keep the windshield washer fluid reservoir filled. . Have good tires with proper tread depth. See Tires 0 344. . Turn off cruise control. Hill and Mountain Roads Driving on steep hills or through mountains is different than driving on flat or rolling terrain. Tips include: . Keep the vehicle serviced and in good shape. . Check all fluid levels and brakes, tires, cooling system, and transmission. . Shift to a lower gear when going down steep or long hills. { Warning Using the brakes to slow the vehicle on a long downhill slope can cause brake overheating, can reduce brake performance, and could result in a loss of braking. Shift the transmission to a lower gear to let the engine assist the brakes on a steep downhill slope. { Warning Coasting downhill in N (Neutral) or with the ignition off is dangerous. This can cause overheating of the brakes and loss of steering assist. Always have the engine running and the vehicle in gear. . Drive at speeds that keep the vehicle in its own lane. Do not swing wide or cross the center line. . Be alert on top of hills; something could be in your lane (e.g., stalled car, crash). . Pay attention to special road signs (e.g., falling rocks area, winding roads, long grades, passing or no-passing zones) and take appropriate action. Winter Driving Driving on Snow or Ice Caution To avoid damage to the wheels and brake components, always clear snow and ice from inside the wheels and underneath the vehicle before driving. Snow or ice between the tires and the road creates less traction or grip, so drive carefully. Wet ice can occur at about 0 °C (32 °F) when freezing rain begins to fall. Avoid driving on wet ice or in freezing rain until roads can be treated. For Slippery Road Driving: . Accelerate gently. Accelerating too quickly causes the wheels to spin and makes the surface under the tires slick. . Turn on Traction Control. See Traction Control/Electronic Stability Control 0 247. . The Antilock Brake System (ABS) improves vehicle stability during hard stops, but the brakes should be applied sooner than when on dry pavement. See Antilock Brake System (ABS) 0 244. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating . Allow greater following distance and watch for slippery spots. Icy patches can occur on otherwise clear roads in shaded areas. The surface of a curve or an overpass can remain icy when the surrounding roads are clear. Avoid sudden steering maneuvers and braking while on ice. . Turn off cruise control. Blizzard Conditions Stop the vehicle in a safe place and signal for help. Stay with the vehicle unless there is help nearby. If possible, use Roadside Assistance. See Roadside Assistance Program 0 412. To get help and keep everyone in the vehicle safe: . Turn on the hazard warning flashers. . Tie a red cloth to an outside mirror. { Warning Snow can trap engine exhaust under the vehicle. This may cause exhaust gases to get inside. Engine exhaust contains carbon monoxide (CO), which cannot be seen or smelled. It can cause unconsciousness and even death. (Continued) 219 If the vehicle is stuck in snow: charged to restart the vehicle and to signal for help with the headlamps. Do this as little as possible, to save fuel. . Clear snow from the base of the If the Vehicle Is Stuck Warning (Continued) vehicle, especially any blocking the exhaust pipe. . Open a window about 5 cm (2 in) on the vehicle side that is away from the wind, to bring in fresh air. . Fully open the air outlets on or under the instrument panel. . Adjust the climate control system to circulate the air inside the vehicle and set the fan speed to the highest setting. See “Climate Control Systems.” For more information about CO, see Engine Exhaust 0 235. To save fuel, run the engine for short periods to warm the vehicle and then shut the engine off and partially close the window. Moving about to keep warm also helps. If it takes time for help to arrive, when running the engine, push the accelerator pedal slightly so the engine runs faster than the idle speed. This keeps the battery Slowly and cautiously spin the wheels to free the vehicle when stuck in sand, mud, ice, or snow. See “Rocking the Vehicle to Get It Out” later in this section. The Traction Control/Electronic Stability Control can often help to free a stuck vehicle. See Traction Control/Electronic Stability Control 0 247. If TC/ESC cannot free the vehicle, see “Rocking the Vehicle to Get it Out” following. { Warning If the vehicle's tires spin at high speed, they can explode, and you or others could be injured. The vehicle can overheat, causing an engine compartment fire or other damage. Spin the wheels as little as possible and avoid going above 56 km/h (35 mph). For information about using tire chains on the vehicle, see Tire Chains 0 362. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 220 Driving and Operating Rocking the Vehicle to Get It Out Caution Do not hold the steering wheel at full rotation for more than 15 seconds and/or at an elevated RPM. Damage may occur to the power steering system and there may be loss of power steering assist. Turn the steering wheel left and right to clear the area around the front wheels. Then make sure the wheels are pointed straight ahead. For four-wheel-drive vehicles, shift into Four-Wheel Drive High. Turn the TCS off. Shift back and forth between R (Reverse) and a forward gear, spinning the wheels as little as possible. To prevent transmission wear, wait until the wheels stop spinning before shifting gears. Slowly spinning the wheels in the forward and reverse directions causes a rocking motion that could free the vehicle. If that does not get the vehicle out after a few tries, it might need to be towed out. See Towing the Vehicle 0 377. Recovery hooks can be used, if the vehicle has them. Recovery Hooks { Warning Never pull on recovery hooks from the side. The hooks could break and you and others could be injured. When using recovery hooks, always pull the vehicle from the front. Caution Never use recovery hooks to tow the vehicle. The vehicle could be damaged, and the repairs would not be covered by the vehicle warranty. If equipped, there are recovery hooks at the front of the vehicle. Use them if the vehicle is stuck off-road and needs to be pulled some place to continue driving. Vehicle Load Limits It is very important to know how much weight the vehicle can carry. This weight is called the vehicle capacity weight and includes the weight of all occupants, cargo, and all nonfactory-installed options. Two labels on the vehicle may show how much weight it was designed to carry: the Tire and Loading Information label and the Certification/Tire label. { Warning Do not load the vehicle any heavier than the Gross Vehicle Weight Rating (GVWR), or either the maximum front or rear Gross Axle Weight Rating (GAWR). This can cause systems to break and change the way the vehicle handles. This could cause loss of control and a crash. (Continued) Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating Warning (Continued) Overloading can also reduce stopping performance, damage the tires, and shorten the life of the vehicle. Tire and Loading Information Label Label Example A vehicle-specific Tire and Loading Information label is attached to the center pillar (B-pillar). The Tire and Loading Information label shows the number of occupant seating positions (1), and the maximum vehicle capacity weight (2) in kilograms and pounds. The Tire and Loading Information label also shows the size of the original equipment tires (3) and the recommended cold tire inflation pressures (4). For more information on tires and inflation see Tires 0 344 and Tire Pressure 0 349. There is also important loading information on the vehicle Certification/ Tire label. It may show the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for the front and rear axles. See “Certification/Tire Label” later in this section. “Steps for Determining Correct Load Limit– 1. Locate the statement "The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs." on your vehicle’s placard. 2. Determine the combined weight of the driver and passengers that will be riding in your vehicle. 221 3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs. 4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the "XXX" amount equals 1400 lbs. and there will be five 150 lb passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs. (1400-750 (5 x 150) = 650 lbs.) 5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4. 6.

See “Loading the Vehicle for Off-Road Driving“ under Off-Road Driving 0 214. Two-Tiered Loading Depending on the model of the pickup, an upper load platform can be created by positioning three or four 5 cm (2 in) by 15 cm (6 in) wooden planks across the width of the pickup box. The planks must be inserted in the pickup box depressions. When using this upper load platform, be sure the load is securely tied down to prevent it from shifting. The load's center of gravity should be positioned in a zone over the rear axle. The zone is located in the area between the front of each wheel well and the rear of each wheel well. The center of gravity height must not extend above the top of the pickup box flareboard. Any load that extends beyond the vehicle's taillamp area must be properly marked according to local laws and regulations. * Equipment Maximum Weight Ladder Rack and Cargo 340 kg (750 lb) Remember not to exceed the Gross Axle Weight Rating (GAWR) of the front or rear axle. Cross Toolbox and 181 kg (400 lb) Cargo Add-On Equipment When carrying removable items, a limit on how many people carried inside the vehicle may be necessary. Be sure to weigh the vehicle before buying and installing the new equipment. Side Boxes and Cargo 113 kg per side (250 lb per side) * The combined weight for all rail-mounted equipment should not exceed 454 kg (1,000 lb). Loading Points Caution Overloading the vehicle may cause damage. Repairs would not be covered by the vehicle warranty. Do not overload the vehicle. Remember not to exceed the Gross Axle Weight Rating (GAWR) of the front or rear axle. 1. Primary Load Points Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

GM Approved Accessory Mounting Points Structural members (1) and (2) are included in the pickup box design. Additional accessories should use these load points. Depending on the accessory design, use a spacer under the accessory at the load points to remove gap. The holes for GM approved accessories (3) are not intended for aftermarket equipment. See www.gmupfitter.com for additional pickup box load bearing structural information. Truck-Camper Loading Information A vehicle-specific Truck-Camper Loading Information label is attached to the inside of the vehicle's glove box. This label indicates if a slide-in camper can be carried, how much of a load the vehicle can carry, and how to correctly spread out the load. It will help to match the right slide-in camper to the vehicle. Your dealer can help make a good vehicle-camper match and help determine the Cargo Weight Rating (CWR). 225 Refer to the Truck-Camper Loading Information label in the glove box for dimensions A and B as shown in the following illustration. When installing and loading a slide-in camper, check the manufacturer's instructions. When carrying a slide-in camper, the total cargo load of the vehicle is the weight of the camper plus: . Everything added to the camper after it left the factory. . Everything in the camper. . All the people inside. The CWR is the maximum weight of the load the vehicle can carry. It does not include the weight of the people inside. But, use about 68 kg (150 lb) for each seat. The total cargo load must not be more than the vehicle's CWR. Use the rear edge of the load floor for measurement purposes. The recommended location for the cargo center of gravity is in zone C for the CWR. It is the point where the mass of a body is concentrated and, if suspended at that point, would balance the front and rear. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 226 Driving and Operating Here is an example of proper truck and camper match: cargo load should not exceed the truck's cargo weight rating, and the camper's center of gravity (1) should fall within the truck's recommended center of gravity zone (2) when installed. Any accessories or other equipment that are added to the vehicle must be weighed. Then, subtract this extra weight from the CWR. This extra weight may shorten the center of gravity zone of the vehicle. 1. Camper Center of Gravity 2. Recommended Center of Gravity Location Zone When the truck is used to carry a slide-in camper, the total cargo load of the truck consists of the manufacturer's camper weight figure, the weight of installed additional camper equipment not included in the manufacturer's camper weight figure, the weight of camper cargo, and the weight of passengers in the camper. The total If the slide-in camper and its load weighs less than the CWR, the center of gravity zone for the vehicle may be larger. Secure loose items to prevent weight shifts that could affect the balance of the vehicle. When the truck-camper is loaded, drive to a scale and weigh on the front and on the rear wheels separately to determine axle loads. Individual axle loads should not exceed either of the gross axle weight ratings (GAWR). The total axle loads should not exceed the vehicle's gross vehicle weight rating (GVWR). These ratings are given on the Certification/Tire label attached to the B-pillar. See “Certification/Tire Label” under Vehicle Load Limits 0 220. If weight ratings are exceeded, move or remove items to bring all weights below the ratings. See your dealer for more information on curb weights, cargo weights, Cargo Weight Rating, and the correct center of gravity zone. Starting and Operating New Vehicle Break-In Caution The vehicle does not need an elaborate break-in. But it will perform better in the long run if you follow these guidelines: . Do not drive at any one constant speed, fast or slow, for the first 800 km (500 mi). Do not make full-throttle starts. Avoid downshifting to brake or slow the vehicle. (Continued) Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating Caution (Continued) . Avoid making hard stops for the first 300 km (200 mi) or so. During this time the new brake linings are not yet broken in. Hard stops with new linings can mean premature wear and earlier replacement. Follow this breaking-in guideline every time you get new brake linings. . Do not tow a trailer during break-in. See Trailer Towing 0 278 for the trailer towing capabilities of the vehicle and more information. Normal driving charges the vehicle’s battery to achieve the best operation of the vehicle, including fuel economy. Ignition Positions (Key Access) 227 0 (Stopping the Engine/LOCK/OFF) : This position turns off the vehicle. It also locks the ignition, the transmission, and the steering column, if equipped with a locking steering column. Following break-in, engine speed and load can be gradually increased. On new vehicles, the various mechanical and electrical systems experience a “break-in” period during the first 6,400 km (4,000 miles) of routine driving. As the vehicle is driven, the mechanical systems adjust to provide optimal fuel economy and transmission shift performance. Electrical systems will adapt and calibrate during the break-in period. A one-time occurrence of clicks and similar vehicle noises is normal during this process. 0. Stopping the Engine/LOCK/OFF 1. ACC/ACCESSORY 2. ON/RUN 3. START The ignition switch has four positions.

S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating Starting Procedure 1. For Key Access vehicles, turn the ignition key to Start. When the engine starts, let go of the key. For Keyless Access vehicles, the RKE transmitter must be in the vehicle. Press ENGINE START/STOP with the brake pedal applied. When the engine begins cranking, let go of the button. The driver may observe a minor, and temporary, brake pedal kickback when starting the vehicle. This is normal. The idle speed will go down as the engine gets warm. Do not race the engine immediately after starting it. Operate the engine and transmission gently to allow the oil to warm up and lubricate all moving parts. When the low fuel warning light is on and the FUEL LEVEL LOW message is displayed in the Driver Information Center (DIC), hold the ignition switch in the START position to continue engine cranking. Caution Cranking the engine for long periods of time, by returning the ignition to the START position immediately after cranking has ended, can overheat and damage the cranking motor, and drain the battery. Wait at least 15 seconds between each try, to let the cranking motor cool down. 2. If the engine does not start after five to 10 seconds, especially in very cold weather (below −18 °C or 0 °F), it could be flooded with too much gasoline. Try pushing the accelerator pedal all the way to the floor and holding it there while holding the key in START or ENGINE START/STOP for up to a maximum of 15 seconds. Wait at least 15 seconds between each try, to allow the cranking motor to cool down. When the engine starts, let go of the key or button and accelerator. If the vehicle starts briefly but then stops again, do the same thing. This clears the extra gasoline from the engine. Do not race the engine immediately after starting it. Operate 231 the engine and transmission gently until the oil warms up and lubricates all moving parts. Engine Heater If equipped, the engine heater can provide easier starting and better fuel economy during engine warm-up in cold weather conditions at or below −18 °C (0 °F). Vehicles with an engine heater should be plugged in at least four hours before starting. An internal thermostat in the plug-end of the cord may exist, which will prevent engine heater operation at temperatures above −18 °C (0 °F). { Warning Do not plug in the engine block heater while the vehicle is parked in a garage or under a carport. Property damage or personal injury may result. Always park the vehicle in a clear open area away from buildings or structures. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 234 Driving and Operating Torque Lock If you are parking on a hill and you do not shift the transmission into P (Park) properly, the weight of the vehicle may put too much force on the parking pawl in the transmission. You may find it difficult to pull the shift lever out of P (Park). This is called torque lock. To prevent torque lock, set the parking brake and then shift into P (Park) properly before you leave the driver seat. When you are ready to drive, move the shift lever out of P (Park) before you release the parking brake. If torque lock does occur, you may need to have another vehicle push yours a little uphill to take some of the pressure from the parking pawl in the transmission. You will then be able to pull the shift lever out of P (Park). Shifting out of Park This vehicle is equipped with an electronic shift lock release system. The system is designed to prevent movement of the shift lever out of P (Park), unless the brake pedal is applied and the ignition is on or in Service Mode. The shift lock release is always functional except in the case of an uncharged or low voltage – less than 9 volt – battery. If the vehicle has an uncharged or low voltage battery, try charging or jump starting the battery. See Jump Starting North America 0 374. To shift out of P (Park): 1. Apply the brake pedal. 2. Release the parking brake if it is applied. See Electric Parking Brake 0 245. 3. Pull the shift lever toward you, then move it to the desired position, and release. If the vehicle still cannot be shifted out of P (Park): 1. Ease the pressure on, or release the shift lever. 2. While holding the brake pedal, push the shift lever all the way into P (Park). 3. Pull the shift lever toward you, then move it to the desired position, and release. If there is still a problem shifting, have the vehicle serviced soon. Parking over Things That Burn { Warning Things that can burn could touch hot exhaust parts under the vehicle and ignite. Do not park over papers, leaves, dry grass, or other things that can burn. Extended Parking It is best not to park with the vehicle running. If the vehicle is left running, be sure it will not move and there is adequate ventilation. See Shifting Into Park 0 233 and Engine Exhaust 0 235. If the vehicle is left parked and running with the RKE transmitter outside the vehicle, it will continue to run for up to 15 minutes. If the vehicle is left parked and running with the RKE transmitter inside the vehicle, it will continue to run for up to 30 minutes. The vehicle could turn off sooner if it is parked on a hill, due to lack of available fuel. The timer will reset if the vehicle is taken out of P (Park) while it is running. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating When the vehicle was produced, it came with the auto-shutdown feature enabled. If you are not the primary owner of your vehicle, please note that this feature may have been disabled by a previous owner. The vehicle owners can have this feature re-enabled at owner cost at any GM service center. Engine Exhaust { Warning Engine exhaust contains carbon monoxide (CO), which cannot be seen or smelled. Exposure to CO can cause unconsciousness and even death. Exhaust may enter the vehicle if: . The vehicle idles in areas with poor ventilation (parking garages, tunnels, deep snow that may block underbody airflow or tail pipes). . The exhaust smells or sounds strange or different. . The exhaust system leaks due to corrosion or damage. (Continued) Warning (Continued) . The vehicle exhaust system has been modified, damaged, or improperly repaired. . There are holes or openings in the vehicle body from damage or aftermarket modifications that are not completely sealed. If unusual fumes are detected or if it is suspected that exhaust is coming into the vehicle: . Drive it only with the windows completely down. . Have the vehicle repaired immediately. Never park the vehicle with the engine running in an enclosed area such as a garage or a building that has no fresh air ventilation. 235 If the vehicle is left with the engine running, follow the proper steps to be sure the vehicle will not move. See Shifting Into Park 0 233 and Engine Exhaust 0 235. If parking on a hill and pulling a trailer, see Driving Characteristics and Towing Tips 0 274. Automatic Transmission If equipped, there is an electronic shift lever position indicator within the instrument cluster. This display comes on when the ignition is in ACC/ACCESSORY, on or service mode. There are several different positions for the shift lever. Running the Vehicle While Parked It is better not to park with the engine running. See Driver Mode Control 0 249 and “Range Selection Mode” under Manual Mode 0 238. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 236 Driving and Operating P : This position locks the rear wheels. Use P (Park) when starting the engine because the vehicle cannot move easily. When parked on a hill, especially when the vehicle has a heavy load, you might notice an increase in the effort to shift out of P (Park). See “Torque Lock” under Shifting Into Park 0 233. { Warning It is dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll. Do not leave the vehicle when the engine is running. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move, even when you are on fairly level ground, always set the parking brake and move the shift lever to P (Park). See Shifting Into Park 0 233 and Driving Characteristics and Towing Tips 0 274. { Warning If equipped with four-wheel drive, the vehicle will be free to roll if the transfer case is in N (Neutral), even when the shift lever is in P (Park). You or someone else could be seriously injured. Be sure the transfer case is in a drive gear — 2 m, 4 m, or 4 n — or set the parking brake before placing the transfer case in N (Neutral). See Four-Wheel Drive 0 240. R : Use this gear to back up. Caution Shifting to R (Reverse) while the vehicle is moving forward could damage the transmission. The repairs would not be covered by the vehicle warranty. Shift to R (Reverse) only after the vehicle is stopped. To rock the vehicle back and forth to get out of snow, ice, or sand without damaging the transmission, see If the Vehicle Is Stuck 0 219. N : In this position, the engine does not connect with the wheels. To restart the engine when the vehicle is already moving, use N (Neutral) only. Also, use N (Neutral) when the vehicle is being towed. { Warning Shifting into a drive gear while the engine is running at high speed is dangerous. Unless your foot is firmly on the brake pedal, the vehicle could move very rapidly. You could lose control and hit people or objects. Do not shift into a drive gear while the engine is running at high speed. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating Caution Shifting out of P (Park) or N (Neutral) with the engine running at high speed may damage the transmission. The repairs would not be covered by the vehicle warranty. Be sure the engine is not running at high speed when shifting the vehicle. Caution A transmission hot message may display if the automatic transmission fluid is too hot. Driving under this condition can damage the vehicle. Stop and idle the engine to cool the automatic transmission fluid. This message clears when the transmission fluid has cooled sufficiently. D : This position is for normal driving. It provides the best fuel economy. If more power is needed for passing, press the accelerator pedal down. . When going less than about 55 km/h (35 mph), push the accelerator pedal about halfway down. . When going about 55 km/h (35 mph) or more, push the accelerator all the way down. By doing this, the vehicle shifts down to the next gear and has more power. Use D (Drive) and Tow/Haul Mode when towing a trailer, carrying a heavy load, driving on steep hills, or driving off-road. Shift the transmission to a lower gear if the transmission shifts too often. Downshifting the transmission in slippery road conditions could result in skidding. See “Skidding” under Loss of Control 0 213. 237 The vehicle has a shift stabilization feature that adjusts the transmission shifting to the current driving conditions in order to reduce rapid upshifts and downshifts. This shift stabilization feature is designed to determine, before making an upshift, if the engine is able to maintain vehicle speed by analyzing things such as vehicle speed, throttle position, and vehicle load. If the shift stabilization feature determines that a current vehicle speed cannot be maintained, the transmission does not upshift and instead holds the current gear. In some cases, this could appear to be a delayed shift, however the transmission is operating normally. The transmission uses adaptive shift controls. The adaptive shift control process continually compares key shift parameters to pre-programmed ideal shifts stored in the transmission’s computer. The transmission constantly makes adjustments to improve vehicle performance according to how the vehicle is being used, such as with a heavy load or when the temperature changes. During this adaptive shift control process, shifting might feel different as the transmission determines the best settings. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 238 Driving and Operating When temperatures are very cold, the transmission's gear shifting could be delayed providing more stable shifts until the engine warms up. Shifts could be more noticeable with a cold transmission. This difference in shifting is normal. L : This position allows selection of a range of gears appropriate for current driving conditions. If equipped, see “Range Selection Mode” under Manual Mode 0 238. Caution Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. The repair will not be covered by the vehicle warranty. If the vehicle is stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place. Manual Mode Range Selection Mode Range Selection Mode helps control the vehicle transmission and vehicle speed while driving downhill or towing a trailer. It permits the manual selection of a desired gear range. To use this feature: 1. Move the shift lever to L (Manual Mode). 2. Press the plus/minus buttons on the shift lever to select the desired gear range for current driving conditions. When the shift lever is moved from D (Drive) to L (Manual Mode), a number displays next to the L, indicating the current transmission range. This number is the highest gear that the transmission will allow while operating in L (Manual Mode). All gears below that number are available. As driving conditions change, the transmission can automatically shift to lower gears. For example, when L5 is selected, 1 (First) through 5 (Fifth) gears are automatically shifted by the transmission, but 6 (Sixth) cannot be used until the plus/ minus button on the shift lever is used to change to the range. In vehicles with gasoline engines, when the shift lever is moved from D (Drive) to L (Manual Mode), a downshift may occur. The gear that the transmission is operating in when the shift lever is moved from D (Drive) to L (Manual Mode) determines if a downshift occurs. See the following charts. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

Antilock Brake System (ABS) The Antilock Brake System (ABS) helps prevent a braking skid and maintain steering while braking hard. ABS performs a system check when the vehicle is first driven. A momentary motor or clicking noise may be heard while this test is going on, and the brake pedal may move slightly. This is normal. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating If there is a problem with ABS, this warning light stays on. See Antilock Brake System (ABS) Warning Light 0 118. Electric Parking Brake ABS does not change the time needed to get a foot on the brake pedal and does not always decrease stopping distance. If you get too close to the vehicle ahead, there will not be enough time to apply the brakes if that vehicle suddenly slows or stops. Always leave enough room ahead to stop, even with ABS. Braking in Emergencies ABS allows steering and braking at the same time. In many emergencies, steering can help even more than braking. Before leaving the vehicle, check the red parking brake status light to ensure that the parking brake is applied. EPB Apply To apply the EPB: 1. Be sure the vehicle is at a complete stop. 2. Press the EPB switch momentarily. Using ABS Do not pump the brakes. Just hold the brake pedal down firmly. Hearing or feeling ABS operate is normal. 245 The Electric Parking Brake (EPB) can always be applied, even if the vehicle is off. In case of insufficient electrical power, the EPB cannot be applied or released. To prevent draining the battery, avoid unnecessary repeated cycles of the EPB. The system has a red parking brake status light and an amber service parking brake warning light. See Electric Parking Brake Light 0 118 and Service Electric Parking Brake Light 0 118. There are also parking brake-related Driver Information Center (DIC) messages. The red parking brake status light will flash and then stay on once the EPB is fully applied. If the red parking brake status light flashes continuously, then the EPB is only partially applied or there is a problem with the EPB. A DIC message will display. Release the EPB and try to apply it again. If the light does not come on, or keeps flashing, have the vehicle serviced. Do not drive the vehicle if the red parking brake status light is flashing. See your dealer. If the amber service parking brake warning light is on, press the EPB switch. Continue to hold the switch until the red parking brake status light remains on. If the amber service parking brake warning light is on, see your dealer. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 246 Driving and Operating If the EPB is applied while the vehicle is moving, the vehicle will decelerate as long as the switch is pressed. If the switch is pressed until the vehicle comes to a stop, the EPB will remain applied. The vehicle may automatically apply the EPB in some situations when the vehicle is not moving. This is normal, and is done to periodically check the correct operation of the EPB system, or at the request of other safety functions that utilize the EPB. If the EPB fails to apply, block the rear wheels to prevent vehicle movement. EPB Release To release the EPB: 1. Turn the ignition on or to ACC/ ACCESSORY. 2. Apply and hold the brake pedal. 3. Press the EPB switch momentarily. The EPB is released when the red parking brake status light is off. If the amber service parking brake warning light is on, release the EPB by pressing and holding the EPB switch. Continue to hold the switch until the red parking brake status light is off. If either light stays on after release is attempted, see your dealer. Caution Driving with the parking brake on can overheat the brake system and cause premature wear or damage to brake system parts. Make sure that the parking brake is fully released and the brake warning light is off before driving. If you are towing a trailer and parking on a hill, see Driving Characteristics and Towing Tips 0 274. Automatic EPB Release The EPB will automatically release if the vehicle is running, placed into gear, and an attempt is made to drive away. Avoid rapid acceleration when the EPB is applied, to preserve parking brake lining life. Brake Assist Brake Assist detects rapid brake pedal applications due to emergency braking situations and provides additional braking to activate the Antilock Brake System (ABS) if the brake pedal is not pushed hard enough to activate ABS normally. Minor noise, brake pedal pulsation, and/or pedal movement during this time may occur. Continue to apply the brake pedal as the driving situation dictates. Brake Assist disengages when the brake pedal is released. Hill Start Assist (HSA) { Warning Do not rely on the HSA feature. HSA does not replace the need to pay attention and drive safely. You may not hear or feel alerts or warnings provided by this system. Failure to use proper care when driving may result in injury, death, or vehicle damage. See Defensive Driving 0 211. When the vehicle is stopped on a grade, Hill Start Assist (HSA) prevents the vehicle from rolling in an unintended direction during the transition from brake pedal release to accelerator pedal apply. The brakes release when the accelerator pedal is applied. If the accelerator pedal is not applied within a few minutes, the Electric Parking Brake will apply. The brakes may also release under other conditions. Do not rely on HSA to hold the vehicle. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating HSA is available when the vehicle is facing uphill in a forward gear, or when facing downhill in R (Reverse). The vehicle must come to a complete stop on a grade for HSA to activate. Ride Control Systems Traction Control/Electronic Stability Control System Operation The vehicle has a Traction Control System (TCS) and StabiliTrak/Electronic Stability Control (ESC) system. These systems help limit wheel spin and assist the driver in maintaining control, especially on slippery road conditions. TCS activates if it senses any of the drive wheels are spinning or beginning to lose traction. When this happens, TCS applies the brakes to the spinning wheels and reduces engine power to limit wheel spin. StabiliTrak/ESC activates when the vehicle senses a difference between the intended path and the direction the vehicle is actually traveling. StabiliTrak/ESC selectively applies braking pressure to any one of the vehicle wheel brakes to assist the driver in keeping the vehicle on the intended path. Trailer Sway Control (TSC) is also on automatically when the vehicle is started. See Trailer Sway Control (TSC) 0 291. 247 Driver Information Center (DIC). Both traction control and StabiliTrak/ESC are automatically disabled in this condition. If cruise control is being used and traction control or StabiliTrak/ESC begins to limit wheel spin, cruise control will disengage. Cruise control may be turned back on when road conditions allow. Both systems come on automatically when the vehicle is started and begins to move. The systems may be heard or felt while they are operating or while performing diagnostic checks. This is normal and does not mean there is a problem with the vehicle. The indicator light for both systems is in the instrument cluster. This light will: . Flash when TCS is limiting wheel spin. . Flash when StabiliTrak/ESC is activated. . Turn on and stay on when either system is not working. It is recommended to leave both systems on for normal driving conditions, but it may be necessary to turn TCS off if the vehicle gets stuck in sand, mud, ice, or snow. See If the Vehicle Is Stuck 0 219 and “Turning the Systems Off and On” later in this section. If either system fails to turn on or to activate, a message displays in the Driver Information Center (DIC), and d comes on and stays on to indicate that the system is inactive and is not assisting the driver in maintaining control. The vehicle is safe to drive, but driving should be adjusted accordingly. When the transfer case (if equipped) is in Four-Wheel Drive Low, the stability system is automatically disabled, g comes on, and the appropriate message will appear on the If d comes on and stays on: 1. Stop the vehicle. 2. Turn the engine off and wait 15 seconds. 3. Start the engine. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 248 Driving and Operating Drive the vehicle. If d comes on and stays on, the vehicle may need more time to diagnose the problem. If the condition persists, see your dealer. Turning the Systems Off and On The button for TCS and StabiliTrak/ESC is on the center stack. Caution Do not repeatedly brake or accelerate heavily when TCS is off. The vehicle driveline could be damaged. To turn off only TCS, press and release g. The traction off light i displays in the instrument cluster. The appropriate message will display in the DIC. To turn TCS on again, press and release g. The traction off light i displayed in the instrument cluster will turn off. If TCS is limiting wheel spin when g is pressed, the system will not turn off until the wheels stop spinning. To turn off both TCS and StabiliTrak/ESC, press and hold g until the traction off light i and the StabiliTrak/ESC OFF light g come on and stay on in the instrument cluster, then release. The appropriate message will display in the DIC. Hill Descent Control (HDC) If equipped, Hill Descent Control (HDC) sets and maintains vehicle speed while driving down steep grades in a forward or reverse gear. The HDC switch is on the center stack, below the climate controls. Press 5 to enable or disable HDC. Vehicle speed must be below 50 km/h (31 mph). To turn TCS and StabiliTrak/ESC on again, press and release g. The traction off light i and the StabiliTrak/ESC OFF light g in the instrument cluster turn off. StabiliTrak/ESC will automatically turn on if the vehicle exceeds 56 km/h (35 mph). Traction control will remain off. The vehicle has a Trailer Sway Control (TSC) feature and a Hill Start Assist (HSA) feature. See Trailer Sway Control (TSC) 0 291 or Hill Start Assist (HSA) 0 246. Adding accessories can affect the vehicle performance. See Accessories and Modifications 0 307. When enabled, the HDC light displays on the instrument cluster. A blinking HDC light indicates the system is actively applying the brakes to maintain vehicle speed. HDC can maintain vehicle speeds between 1 and 22 km/h (1 and 14 mph) on grades greater than or equal to 10%. If HDC is to be used for more than three minutes or on grades steeper than 25%, the transfer case should be put into Four-Wheel Drive Low (4 n) to reduce the possibility of brake overheating. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating Noise from the Electronic Brake Control Module (EBCM) is normal when HDC is active. When HDC is activated, the initial HDC speed is set to the current driving speed. It can be increased or decreased by pressing +RES or SET- on the steering wheel, or by applying the accelerator or brake pedal. This adjusted speed becomes the new set speed. HDC will remain enabled between 30 and 60 km/h (19 and 37 mph); however, vehicle speed cannot be set or maintained in this range. HDC will automatically disable if the vehicle speed is above 80 km/h (50 mph) or above 60 km/h (37 mph) for at least 30 seconds. Driver Mode Control Modes: Driver Mode Control (DMC) allows the driver to adjust the overall driving experience to better suit preference by adjusting multiple systems to fit specific driving needs. Drive mode availability and affected vehicle subsystems are dependent upon vehicle trim level, region, and optional features. Normal Mode : Use for normal city and highway driving to provide a smooth ride. This setting provides balance between comfort and handling. This is the standard/ default mode. There is no persistent indicator in the instrument cluster for this mode. Mode Activation 6 Snow/Ice Mode : Snow/Ice Mode improves vehicle acceleration on snow and ice covered roads. When active, Snow/Ice Mode will adjust acceleration to optimize traction on slippery surfaces. This can compromise the acceleration on dry asphalt. This feature is not intended for use when the vehicle is stuck in sand, mud, ice, snow, or gravel. If the vehicle becomes stuck, see If the Vehicle Is Stuck 0 219. 5 must be pressed again to re-enable HDC. HDC may disable after an extended period of use. If this happens, HDC will require time to cool down. The length of time HDC remains active depends on road conditions, grade, set speed, vehicle loading, and outside temperature. When enabled, if the vehicle speed is above 30 km/h (19 mph) and below 60 km/h (37 mph), a DIC message will display. 249 To activate Tow/Haul Mode turn the knob counterclockwise. To activate other drive modes turn the knob clockwise. 7 Off-Road Mode : Use this mode for off-road recreational driving. Off-Road Mode should be used to improve driving at moderate speeds, on grass, gravel, dirt, unpaved roads, or snow-covered roads. The accelerator pedal is tuned for off-road use. This mode modifies pedal mapping, transmission shift pattern, Antilock Brake Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

System (ABS), StabiliTrak/Electronic Stability Control (ESC), and Traction Control System (TCS) performance. when hauling heavy loads to provide increased performance and vehicle control. Tow/Haul Mode adjusts the transmission shift pattern, trailer sway, and steering. If the vehicle is turned off with Tow/Haul Mode active and then restarted within four hours or less, Tow/Haul will remain active. Otherwise, the vehicle will start in Normal Mode. If the vehicle has a diesel engine, exhaust braking is automatically activated when Tow/Haul Mode is selected. It maintains vehicle speed by automatically implementing a shift pattern that uses the engine and the transmission to slow the vehicle. The system will command downshifts and use the turbocharger on the engine to reduce vehicle speed when the brake is applied. The normal tow/haul shift pattern will return once the vehicle is on a low grade or when the accelerator pedal is pressed. Locking Rear Axle Vehicles with a locking rear axle can give more traction on snow, mud, ice, sand, or gravel. It works like a standard axle most of the time, but when traction is low, this feature will allow the rear wheel with the most traction to move the vehicle. Cruise Control { Warning Cruise control can be dangerous where you cannot drive safely at a steady speed. Do not use cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause (Continued) Warning (Continued) excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads. If equipped with cruise control, a speed of about 40 km/h (25 mph) or more can be maintained without keeping your foot on the accelerator. Cruise control does not work at speeds below about 40 km/h (25 mph). If the cruise control is being used and the Traction Control System (TCS) or StabiliTrak/ Electronic Stability Control (ESC) begins to limit wheel spin, the cruise control will automatically disengage. See Traction Control/Electronic Stability Control 0 247. If a collision alert occurs when cruise control is activated, cruise control is disengaged. See Forward Collision Alert (FCA) System 0 263. When road conditions allow you to safely use it again, cruise control can be turned back on. Turning off the TCS or StabiliTrak/ESC system will disengage the cruise control. If the brakes are applied, cruise control disengages. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

When an object is detected, either three beeps sound from the left or right or three Safety Alert Seat pulses occur on the left or right side, depending on the direction of the detected vehicle. Use caution while backing up when towing a trailer, as the RCTA detection zones that extend out from the back of the vehicle do not move further back when a trailer is towed. RCTA is disabled when the trailer connection status is displayed. RCTA can be turned off. See “Collision/ Detection Systems” under Vehicle Personalization 0 131. Assistance Systems for Driving If equipped, when driving the vehicle in a forward gear, Forward Collision Alert (FCA), Lane Departure Warning (LDW), Side Blind Zone Alert (SBZA), Lane Change Alert (LCA), and/or the Automatic Emergency Braking (AEB) can help to avoid a crash or reduce crash damage. Forward Collision Alert (FCA) System If equipped, the FCA system may help to avoid or reduce the harm caused by front-end crashes. When approaching a vehicle ahead too quickly, FCA provides a red flashing alert on the windshield and rapidly beeps. FCA also lights an amber visual alert if following another vehicle much too closely. FCA detects vehicles within a distance of approximately 60 m (197 ft) and operates at speeds above 8 km/h (5 mph). 263 Warning (Continued) objects. Be ready to take action and apply the brakes. See Defensive Driving 0 211. FCA can be disabled through vehicle personalization. See “Collision/Detection Systems” under Vehicle Personalization 0 131. Detecting the Vehicle Ahead { Warning FCA is a warning system and does not apply the brakes. When approaching a slower-moving or stopped vehicle ahead too rapidly, or when following a vehicle too closely, FCA may not provide a warning with enough time to help avoid a crash. It also may not provide any warning at all. FCA does not warn of pedestrians, animals, signs, guardrails, bridges, construction barrels, or other (Continued) FCA warnings will not occur unless the FCA system detects a vehicle ahead. When a vehicle is detected, the vehicle ahead indicator will display green. Vehicles may not be detected on curves, highway exit ramps, or hills, due to poor visibility; or if a vehicle ahead is partially blocked by pedestrians or other objects. FCA will not detect another vehicle ahead until it is completely in the driving lane. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 264 Driving and Operating The vehicle ahead indicator will display amber when you are following a vehicle ahead much too closely. { Warning FCA does not provide a warning to help avoid a crash, unless it detects a vehicle. FCA may not detect a vehicle ahead if the FCA sensor is blocked by dirt, snow, or ice, or if the windshield is damaged. It may also not detect a vehicle on winding or hilly roads, or in conditions that can limit visibility such as fog, rain, or snow, or if the headlamps or windshield are not cleaned or in proper condition. Keep the windshield, headlamps, and FCA sensors clean and in good repair. Collision Alert Selecting the Alert Timing Without Head-Up Display When your vehicle approaches another detected vehicle too rapidly, the red FCA display will flash on the windshield. Also, eight rapid high-pitched beeps will sound from the front, or both sides of the Safety Alert Seat will pulse five times. When this Collision Alert occurs, the brake system may prepare for driver braking to occur more rapidly which can cause a brief, mild deceleration. Continue to apply the brake pedal as needed. Cruise control may be disengaged when the Collision Alert occurs. Tailgating Alert The Collision Alert control is on the steering wheel. Press [ to set the FCA timing to Far, Medium, or Near. The first button press shows the current setting on the DIC. Additional button presses will change this setting. The chosen setting will remain until it is changed and will affect the timing of both the Collision Alert and the Tailgating Alert features. The timing of both alerts will vary based on vehicle speed. The faster the vehicle speed, the farther away the alert will occur. Consider traffic and weather conditions when selecting the alert timing. The range of selectable alert timings may not be appropriate for all drivers and driving conditions. Unnecessary Alerts With Head-Up Display FCA may provide unnecessary alerts for turning vehicles, vehicles in other lanes, objects that are not vehicles, or shadows. These alerts are normal operation and the vehicle does not need service. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating Cleaning the System If the FCA system does not seem to operate properly, this may correct the issue: . Clean the outside of the windshield in front of the rearview mirror. . Clean the entire front of the vehicle. . Clean the headlamps. Automatic Emergency Braking (AEB) If equipped, the AEB system may help avoid or reduce the harm caused by front-end crashes. AEB also includes Intelligent Brake Assist (IBA). When the system detects a vehicle ahead in your path that is traveling in the same direction that you may be about to crash into, it can provide a boost to braking or automatically brake the vehicle. This can help avoid or lessen the severity of crashes when driving in a forward gear. Depending on the situation, the vehicle may automatically brake moderately or hard. This automatic emergency braking can only occur if a vehicle is detected. This is shown by the FCA vehicle ahead indicator being lit. See Forward Collision Alert (FCA) System 0 263. The system works when driving in a forward gear between 8 km/h (5 mph) and 80 km/h (50 mph). It can detect vehicles up to approximately 60 m (197 ft). { Warning AEB is an emergency crash preparation feature and is not designed to avoid crashes. Do not rely on AEB to brake the vehicle. AEB will not brake outside of its operating speed range and only responds to detected vehicles. AEB may not: . Detect a vehicle ahead on winding or hilly roads. . Detect all vehicles, especially vehicles with a trailer, tractors, muddy vehicles, etc. . Detect a vehicle when weather limits visibility, such as in fog, rain, or snow. . Detect a vehicle ahead if it is partially blocked by pedestrians or other objects. (Continued) 265 Warning (Continued) Complete attention is always required while driving, and you should be ready to take action and apply the brakes and/or steer the vehicle to avoid crashes. AEB may slow the vehicle to a complete stop to try to avoid a potential crash. If this happens, AEB may engage the Electric Parking Brake (EPB) to hold the vehicle at a stop. Release the EPB or firmly press the accelerator pedal. { Warning AEB may automatically brake the vehicle suddenly in situations where it is unexpected and undesired. It could respond to a turning vehicle ahead, guardrails, signs, and other non-moving objects. To override AEB, firmly press the accelerator pedal, if it is safe to do so. Intelligent Brake Assist (IBA) IBA may activate when the brake pedal is applied quickly by providing a boost to braking based on the speed of approach and distance to a vehicle ahead. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 266 Driving and Operating Minor brake pedal pulsations or pedal movement during this time is normal and the brake pedal should continue to be applied as needed. IBA will automatically disengage only when the brake pedal is released. { Warning IBA may increase vehicle braking in situations when it may not be necessary. You could block the flow of traffic. If this occurs, take your foot off the brake pedal and then apply the brakes as needed. AEB and IBA can be disabled. See “Collision/ Detection Systems” under Vehicle Personalization 0 131. { Warning Using AEB or IBA while towing a trailer could cause you to lose control of the vehicle and crash. Turn the system to Alert or Off when towing a trailer. A system unavailable message may display if: . The front of the vehicle or windshield is not clean. . Heavy rain or snow is interfering with object detection. . There is a problem with the StabiliTrak/ Electronic Stability Control (ESC) system. The AEB system does not need service. Side Blind Zone Alert (SBZA) If equipped, the SBZA system is a lane-changing aid that assists drivers with avoiding crashes that occur with moving vehicles in the side blind zone, or blind spot areas. When the vehicle is in a forward gear, the left or right side mirror display will light up if a moving vehicle is detected in that blind zone. If the turn signal is activated and a vehicle is also detected on the same side, the display will flash as an extra warning not to change lanes. Since this system is part of the Lane Change Alert (LCA) system, read the entire LCA section before using this feature. LCA warning display will light up in the corresponding outside side mirror and will flash if the turn signal is on. { Warning LCA does not alert the driver to vehicles outside of the system detection zones, pedestrians, bicyclists, or animals. It may not provide alerts when changing lanes under all driving conditions. Failure to use proper care when changing lanes may result in injury, death, or vehicle damage. Before making a lane change, always check mirrors, glance over your shoulder, and use the turn signals. LCA Detection Zones Lane Change Alert (LCA) If equipped, the LCA system is a lane-changing aid that assists drivers with avoiding lane change crashes that occur with moving vehicles in the side blind zone (or spot) areas or with vehicles rapidly approaching these areas from behind. The 1. SBZA Detection Zone 2. LCA Detection Zone Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating The LCA sensor covers a zone of approximately one lane over from both sides of the vehicle, or 3.5 m (11 ft). The height of the zone is approximately between 0.5 m (1.5 ft) and 2 m (6 ft) off the ground. The Side Blind Zone Alert (SBZA) warning area starts at approximately the middle of the vehicle and goes back 5 m (16 ft). Drivers are also warned of vehicles rapidly approaching from up to 70 m (230 ft) behind the vehicle. When the vehicle is started, both outside mirror LCA displays will briefly come on to indicate the system is operating. When the vehicle is in a forward gear, the left or right side mirror display will light up if a moving vehicle is detected in the next lane over in that blind zone or rapidly approaching that zone. If the turn signal is activated in the same direction as a detected vehicle, this display will flash as an extra warning not to change lanes. How the System Works LCA can be disabled through vehicle personalization. When you disable LCA, SBZA is also disabled. See Vehicle Personalization 0 131. If LCA is disabled by the driver, the LCA mirror displays will not light up. The LCA symbol lights up in the side mirrors when the system detects a moving vehicle in the next lane over that is in the side blind zone or rapidly approaching that zone from behind. A lit LCA symbol indicates it may be unsafe to change lanes. Before making a lane change, check the LCA display, check mirrors, glance over your shoulder, and use the turn signals. Left Side Mirror Display Right Side Mirror Display When the System Does Not Seem to Work Properly The LCA system requires some driving for the system to calibrate to maximum performance. This calibration may occur more quickly if the vehicle is driving on a straight highway road with traffic and roadside objects (e.g., guardrails, barriers). LCA displays may not come on when passing a vehicle quickly, for a stopped vehicle, or when towing a trailer. The LCA detection zones that extend back from the 267 side of the vehicle do not move further back when a trailer is towed. Use caution while changing lanes when towing a trailer. LCA may alert to objects attached to the vehicle, such as a trailer, bicycle, or object extending out to either side of the vehicle. Attached objects may also interfere with the detection of vehicles. This is normal system operation; the vehicle does not need service. LCA may not always alert the driver to vehicles in the next lane over, especially in wet conditions or when driving on sharp curves. The system does not need to be serviced. The system may light up due to guardrails, signs, trees, shrubs, and other non-moving objects. This is normal system operation; the vehicle does not need service. LCA may not operate when the LCA sensors in the left or right corners of the rear bumper are covered with mud, dirt, snow, ice, or slush, or in heavy rainstorms. For cleaning instructions, see "Washing the Vehicle" under Exterior Care 0 381. If the DIC still displays the system unavailable message after cleaning both sides of the vehicle toward the rear corners of the vehicle, see your dealer. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 268 Driving and Operating If the LCA displays do not light up when moving vehicles are in the side blind zone or are rapidly approaching this zone and the system is clean, the system may need service.

This can occur if the windshield or headlamps are blocked by dirt, snow, or ice; if they are not in proper condition; or if the sun shines directly into the camera. . Detect road edges. . Detect lanes on winding or hilly roads. Lane Departure Warning (LDW) If equipped, LDW may help avoid crashes due to unintentional lane departures. LDW uses a camera sensor to detect the lane markings at speeds of 56 km/h (35 mph) or greater. It may provide an alert if the vehicle is crossing a lane without using a turn signal in that direction. LDW light will not alert if the turn signal is active in the direction of lane departure, or if LDW detects that you are accelerating, braking or actively steering. If LDW only detects lane markings on one side of the road, it will only warn you when departing the lane on the side where it has detected a lane marking. Always keep your attention on the road and maintain proper vehicle position within the lane, or vehicle damage, injury, or death could occur. Always keep the windshield, headlamps, and camera sensors clean and in good repair. Do not use LDW in bad weather conditions. How the System Works LDW utilizes a camera sensor installed on the windshield ahead of the rearview mirror to detect lane markings. To turn LDW on and off, press @ on the center stack. The control indicator will light when LDW is on. When LDW is on, @ is green if LDW is available to warn of a lane departure. If the vehicle crosses a detected lane marking without using the turn signal in that direction, @ changes to amber and flashes. Additionally, there will be three beeps, on the right or left, depending on the lane departure direction. LDW will not alert if the turn signal is active in the direction of lane departure or if LDA detects that you are accelerating, braking or actively steering. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating Prohibited Fuels Fuel Caution Top Tier Fuel GM recommends the use of TOP TIER Detergent Gasoline to keep the engine clean, reduce engine deposits, and maintain optimal vehicle performance. Look for the TOP TIER Logo or see www.toptiergas.com for a list of TOP TIER Detergent Gasoline marketers and applicable countries. If the vehicle has a yellow sticker on the fuel door, E85 or FlexFuel can be used. If the vehicle does not have a yellow sticker, do not use gasoline with ethanol levels greater than 15% by volume. See E85 or FlexFuel 0 270. Regular unleaded gasoline meeting ASTM specification D4814 with a posted octane rating (R+M)/2 of 87 or greater is recommended. Do not use gasoline with a posted octane rating of less than 87, as this will result in reduced performance and driveability. If heavy knocking is heard when using gasoline rated at 87 or greater, the engine needs service. Recommended Fuel For diesel engine vehicles, see “Fuel for Diesel Engines” in the Duramax diesel supplement. 269 Do not use fuels with any of the following conditions; doing so may damage the vehicle and void its warranty: . For vehicles that are not FlexFuel, fuel labeled greater than 15% ethanol by volume, such as mid-level ethanol blends (16–50% ethanol), E85, or FlexFuel. . Fuel with any amount of methanol, methylal, ferrocene, and aniline. These fuels can corrode metal fuel system parts or damage plastic and rubber parts. . Fuel containing metals such as methylcyclopentadienyl manganese tricarbonyl (MMT), which can damage the emissions control system and spark plugs. . Fuel with a posted octane rating of less than the recommended fuel. Using this fuel will lower fuel economy and performance, and may decrease the life of the emissions catalyst. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

For fuel not to use in a foreign country, see Prohibited Fuels 0 269. Fuel Additives TOP TIER Detergent Gasoline is highly recommended for use with your vehicle. If your country does not have TOP TIER Detergent Gasoline, add ACDelco Fuel System Treatment Plus−Gasoline to the vehicle’s gasoline fuel tank at every oil change or 15 000 km (9,000 mi), whichever occurs first. TOP TIER Detergent Gasoline and ACDelco Fuel System Treatment Plus −Gasoline will help keep your vehicle’s engine fuel deposit free and performing optimally. E85 or FlexFuel Vehicles with a yellow fuel sticker on the fuel door can use either unleaded gasoline or fuel containing up to 85% ethanol (E85). All other vehicles should use only the unleaded gasoline as described in Recommended Fuel 0 269. The use of E85 or FlexFuel is encouraged when the vehicle is designed to use it. E85 or FlexFuel is made from renewable sources. To help locate fuel stations that carry E85 or FlexFuel, the U.S. Department of Energy has an alternative fuel website. See www.afdc.energy.gov/afdc/locator/stations. E85 or FlexFuel should meet ASTM Specification D 5798 or CAN/CGSB–3.512 in Canada. Do not use the fuel if the ethanol content is greater than 85%. Fuel mixtures that do not meet ASTM or CGSB specifications can affect driveability and could cause the malfunction indicator lamp to come on. The starting characteristics of E85 or FlexFuel make it unsuitable for use when temperatures fall below −18 °C (0 °F). Use gasoline or add gasoline to the E85 or FlexFuel. Because E85 or FlexFuel has less energy per liter (gallon) than gasoline, the vehicle will need to be refilled more often. See Filling the Tank (Chassis Cab and Box Delete Models) 0 272 or Filling the Tank (Pickup Models) 0 271. The only GM approved aftermarket additive is ACDelco Fuel System Treatment Plus-FlexFuel. Follow the instructions on the bottle for proper use. This product is available at your GM dealer. Caution Some additives are not compatible with E85 or FlexFuel and can harm the vehicle's fuel system. Use only additives approved by GM for E85 or FlexFuel vehicles. Damage caused by unapproved additives would not be covered by the vehicle warranty. Caution Do not use fuel containing methanol. It can corrode metal parts in the fuel system and also damage plastic and rubber parts. That damage would not be covered under the vehicle warranty. To help keep the engine running efficiently, fill the tank with gasoline, up to E15, after filling the tank with E85 one or two times. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

Trailer Towing General Towing Information Only use towing equipment that has been designed for the vehicle. Contact your dealer or trailering dealer for assistance with preparing the vehicle to tow a trailer. Read the entire section before towing a trailer. To tow a disabled vehicle, see Towing the Vehicle 0 377. To tow the vehicle behind another vehicle such as a motor home, see Recreational Vehicle Towing 0 378. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 274 Driving and Operating Driving Characteristics and Towing Tips { Warning You can lose control when towing a trailer if the correct equipment is not used or the vehicle is not driven properly. For example, if the trailer is too heavy or the trailer brakes are inadequate for the load, the vehicle may not stop as expected. You and others could be seriously injured. The vehicle may also be damaged, and the repairs would not be covered by the vehicle warranty. Pull a trailer only if all the steps in this section have been followed. Ask your dealer for advice and information about towing a trailer with the vehicle. Driving with a Trailer Trailering is different than just driving the vehicle by itself. Trailering means changes in handling, acceleration, braking, durability, and fuel economy. Successful, safe trailering takes correct equipment, and it has to be used properly. The following information has many time-tested, important trailering tips and safety rules. Many of these are important for your safety and that of your passengers. Read this section carefully before pulling a trailer. When towing a trailer: . Become familiar with and follow all state and local laws that apply to trailer towing. These requirements vary from state to state. . State laws may require the use of extended side view mirrors. Even if not required, you should install extended side view mirrors if your visibility is limited or restricted while towing. . Do not tow a trailer during the first 800 km (500 mi) of vehicle use to prevent damage to the engine, axle, or other parts. . It is recommended to perform the first oil change before heavy towing. . During the first 800 km (500 mi) of trailer towing, do not drive over 80 km/h (50 mph) and do not make starts at full throttle. . Vehicles can tow in D (Drive). Tow/Haul Mode is recommended for heavier trailers. See Tow/Haul Mode 0 240. If the transmission downshifts too often, a lower gear may be selected using Manual Mode. See Manual Mode 0 238. If equipped, the following driver assistance features should be turned off when towing a trailer: . Park Assist . Automatic Parking Assist (APA) . Reverse Automatic Braking (RAB) If equipped, the following driver assistance features should be turned to alert or off when towing a trailer, unless equipped with Super Cruise: . Automatic Emergency Braking (AEB) . Front Pedestrian Braking (FPB) If equipped with Lane Change Alert (LCA), the LCA detection zones that extend back from the side of the vehicle do not move further back when a trailer is towed. Use caution while changing lanes when towing a trailer. If equipped with Rear Cross Traffic Alert (RCTA), use caution while backing up when towing a trailer, as the RCTA detection zones that extend out from the back of the vehicle do not move further back when a trailer is towed. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating { Warning To prevent serious injury or death from carbon monoxide (CO), when towing a trailer: . Do not drive with the liftgate, trunk/ hatch, or rear-most window open. . Fully open the air outlets on or under the instrument panel. . Adjust the climate control system to a setting that brings in only outside air. See “Climate Control Systems” in the Index. For more information about carbon monoxide, see Engine Exhaust 0 235. and attachments, safety chains, electrical connectors, lamps, tires, and mirrors. See Towing Equipment 0 281. If the trailer has electric brakes, start the combination moving and then manually apply the trailer brake controller to check that the trailer brakes work. During the trip, occasionally check that the cargo and trailer are secure and that the lamps and any trailer brakes are working. Towing with a Stability Control System When towing, the stability control system might be heard. The system reacts to vehicle movement caused by the trailer, which mainly occurs during cornering. This is normal when towing heavier trailers. Towing a trailer requires experience. The combination of the vehicle and trailer is longer and not as responsive as the vehicle itself. Get used to the handling and braking of the combination by driving on a level road surface before driving on public roads. Following Distance The trailer structure, the tires, and the brakes must all be rated to carry the intended cargo. Inadequate trailer equipment can cause the combination to operate in an unexpected or unsafe manner. Before driving, inspect all trailer hitch parts Passing Stay at least twice as far behind the vehicle ahead as you would when driving without a trailer. This can help to avoid heavy braking and sudden turns. More passing distance is needed when towing a trailer. The combination of the vehicle and trailer will not accelerate as quickly and is much longer than the vehicle alone. It is necessary to go much farther 275 beyond the passed vehicle before returning to the lane. Pass on level roadways. Avoid passing on hills if possible. Backing Up Hold the bottom of the steering wheel with one hand. To move the trailer to the left, move that hand to the left. To move the trailer to the right, move that hand to the right. Always back up slowly and, if possible, have someone guide you. Making Turns Caution Turn more slowly and make wider arcs when towing a trailer to prevent damage to your vehicle. Making very sharp turns could cause the trailer to contact the vehicle. Make wider turns than normal when towing, so the trailer will not go over soft shoulders, over curbs, or strike road signs, trees, or other objects. Always signal turns well in advance. Do not steer or brake suddenly. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 276 Driving and Operating Driving on Grades Reduce speed and shift to a lower gear before starting down a long or steep downhill grade. If the transmission is not shifted down, the brakes may overheat and result in reduced braking efficiency. The vehicle can tow in D (Drive). Shift the transmission to a lower gear if the transmission shifts too often under heavy loads and/or hilly conditions. Parking on Hills { Warning To prevent serious injury or death, always park your vehicle and trailer on a level surface when possible. When towing at higher altitudes, engine coolant will boil at a lower temperature than at lower altitudes. If the engine is turned off immediately after towing at high altitude on steep uphill grades, the vehicle could show signs similar to engine overheating. To avoid this, let the engine run, preferably on level ground, with the transmission in P (Park) for a few minutes before turning the engine off. If the overheat warning comes on, see Engine Overheating 0 318. When parking your vehicle and your trailer on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn the wheels into the curb if facing downhill or into traffic if facing uphill. 2. Have someone place chocks under the trailer wheels. 3. Gradually release the brake pedal to allow the chocks to absorb the load of the trailer. 4. Reapply the brake pedal. Then apply the parking brake and shift into P (Park). 5. Release the brake pedal. Viewing Systems Leaving After Parking on a Hill If equipped, the viewing systems on the vehicle can improve visibility while hitching, backing, and driving with a trailer. See Driver Assistance Systems 0 252. 1. Apply and hold the brake pedal. . Start the engine. . Shift into a gear. . Release the parking brake. 2. Let up on the brake pedal. 3. Drive slowly until the trailer is clear of the chocks. 4. Stop and have someone pick up and store the chocks. Launching and Retrieving a Boat Backing the Trailer into the Water { Warning . Have all passengers get out of the vehicle before backing onto the sloped part of the ramp. Lower the driver and passenger side windows before backing onto the ramp. This will provide a means of escape in the unlikely event the vehicle slides into the water. . If the boat launch surface is slippery, have the driver remain in the vehicle with the brake pedal applied while the boat is being launched. The boat launch can be especially slippery at low tide when part of the ramp was previously submerged at high tide. Do not back onto the ramp to launch the boat if you are not sure the vehicle can maintain traction. (Continued) Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating Warning (Continued) . Do not move the vehicle if someone is in the path of the trailer. Some parts of the trailer might be underwater and not visible to people who are assisting in launching the boat. 5. Gradually release the brake pedal to allow the chocks to absorb the load of the trailer. 6. Reapply the brake pedal. Then apply the parking brake and shift into P (Park). 7. Release the brake pedal. Pulling the Trailer from the Water Disconnect the wiring to the trailer before backing the trailer into the water to prevent damage to the electrical circuits on the trailer. Reconnect the wiring to the trailer after removing the trailer from the water. If the trailer has electric brakes that can function when the trailer is submerged, it might help to leave the electrical trailer connector attached to maintain trailer brake functionality while on the boat ramp. To back the trailer into the water: 1. If equipped, place the vehicle in four-wheel-drive high. 2. Slowly back down the boat ramp until the boat is floating, but no further than necessary. 3. Press and hold the brake pedal, but do not shift into P (Park) yet. 4. Have someone place chocks under the front wheels of the vehicle. To 1. 2. 3. 4. 5. pull the trailer out of the water: Press and hold the brake pedal. Start the engine and shift into gear. Release the parking brake. Let up on the brake pedal. Drive slowly until the tires are clear of the chocks. 6. Stop and have someone pick up and store the chocks. 7. Slowly pull the trailer from the water. 8. Once the vehicle and trailer have been driven from the sloped part of the boat ramp, the vehicle can be shifted from four-wheel-drive high. Shift into the drive mode that is appropriate for the road conditions. 277 Caution If the vehicle tires begin to spin and the vehicle begins to slide toward the water, remove your foot from the accelerator pedal and apply the brake pedal. Seek help to have the vehicle towed up the ramp. Maintenance when Trailer Towing The vehicle needs service more often when used to tow trailers. See Maintenance Schedule 0 392. It is especially important to check the engine oil, axle lubricant, belts, cooling system, and brake system before and during each trip. Check periodically to see that all nuts and bolts on the trailer hitch are tight. Engine Cooling When Trailer Towing The cooling system may temporarily overheat during severe operating conditions. See Engine Overheating 0 318. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 278 Driving and Operating Trailer Towing If equipped with a diesel engine, see the Duramax diesel supplement. Caution Towing a trailer improperly can damage the vehicle and result in costly repairs not covered by the vehicle warranty. To tow a trailer correctly, follow the directions in this section and see your dealer for important information about towing a trailer with the vehicle. Trailering is different than just driving the vehicle by itself. Trailering means changes in handling, acceleration, braking, durability, and fuel economy. Successful, safe trailering takes correct equipment, and it has to be used properly. The following information has many time-tested, important trailering tips and safety rules. Many of these are important for your safety and that of your passengers. Read this section carefully before pulling a trailer. Trailer Weight { Warning Never exceed the towing capacity for your vehicle. Safe trailering requires monitoring the weight, speed, altitude, road grades, outside temperature, and how frequently the vehicle is used to tow a trailer. Trailer Weight Ratings When towing a trailer, the combined weight of the vehicle, vehicle contents, trailer, and trailer contents must be below all of the maximum weight ratings for the vehicle, including: . GCWR: Gross Combined Weight Rating . GVWR: Gross Vehicle Weight Rating . Maximum Trailer Weight Rating . GAWR-RR: Gross Axle Weight Rating-Rear . Maximum Trailer Tongue Weight Rating See “Weight-Distributing Hitch and Adjustment” under Towing Equipment 0 281 to determine if equalizer bars are required to obtain the maximum trailer weight rating. See “Trailer Brakes” under Towing Equipment 0 281 to determine if brakes are required based on your trailer's weight. The only way to be sure the weight is not exceeding any of these ratings is to weigh the tow vehicle and trailer combination, fully loaded for the trip, getting individual weights for each of these items. A trailering information label on the B-pillar shows tow rating information for the vehicle. { Warning You and others could be seriously injured or killed if the trailer is too heavy or the trailer brakes are inadequate for the load. The vehicle may be damaged, and the repairs would not be covered by the vehicle warranty. Only tow a trailer if all the steps in this section have been followed. Ask your dealer for advice and information about towing a trailer. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating Gross Combined Weight Rating (GCWR) GCWR is the total allowable weight of the completely loaded vehicle and trailer including any fuel, passengers, cargo, equipment, and accessories. Do not exceed the GCWR for your vehicle. The GCWR for the vehicle is on the Trailering Information Label. To check that the weight of the vehicle and trailer are within the GCWR for the vehicle, follow these steps: 1. Start with the "curb weight" from the Trailering Information Label. 2. Add the weight of the trailer loaded with cargo and ready for the trip. 3. Add the weight of all passengers. 4. Add the weight of all cargo in the vehicle. 5. Add the weight of hitch hardware such as a draw bar, ball, load equalizer bars, or sway bars. 6. Add the weight of any accessories or aftermarket equipment added to the vehicle. The resulting weight cannot exceed the GCWR value on the Trailering Information Label. The gross combined weight can also be confirmed by weighing the truck and trailer on a public scale. The truck and trailer should be loaded for the trip with passengers and cargo. 279 Maximum Trailer Weight The maximum trailer weight rating is calculated assuming the tow vehicle has a driver, a front seat passenger, and all required trailering equipment. This value represents the heaviest trailer the vehicle can tow, but it may be necessary to reduce the trailer weight to stay within the GCWR, GVWR, maximum trailer tongue load, or GAWR-RR for the vehicle. Use the Tow Rating Guide (my.chevrolet.com/learn) to determine how much the trailer can weigh, based on the vehicle model and options. Weights listed apply for conventional trailers and gooseneck/fifth-wheel trailers unless otherwise noted. Gross Vehicle Weight Rating (GVWR) For information about the vehicle's maximum load capacity, see Vehicle Load Limits 0 220. When calculating the GVWR with a trailer attached, the trailer tongue weight must be included as part of the weight the vehicle is carrying. A step bumper trailer hitch can only support a total trailer weight up to 2 271 kg (5,000 lb). If a trailer hitch ball is added to the step bumper, check the hitch ball rating to be sure it is higher than the total trailer weight. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 280 Driving and Operating Maximum Trailer Tongue Weight Rating The Maximum Trailer Tongue Weight Rating is the allowable trailer tongue weight that the vehicle can support using a conventional trailer hitch. It may be necessary to reduce the overall trailer weight to stay within the maximum trailer tongue weight rating while still maintaining the correct trailer load balance. A fifth-wheel or gooseneck hitch may support a higher tongue weight. Do not exceed a maximum trailer tongue weight of 567 kg (1,250 lb) for a conventional trailer hitch. The trailer tongue weight contributes to the Gross Vehicle Weight (GVW). GVW includes the curb weight of your vehicle, any passengers, cargo, equipment and the trailer tongue weight. Vehicle options, passengers, cargo, and equipment reduce the maximum allowable tongue weight the vehicle can carry, which also reduces the maximum allowable trailer weight. Trailer Load Balance The correct trailer load balance must be maintained to ensure trailer stability. Incorrect load balance is a leading cause of trailer sway. The Maximum Trailer Tongue Weight Rating for a conventional trailer hitch or a fifth wheel/gooseneck hitch is shown on the Trailering Information Label. The trailer tongue weight (1) should be 10– 15% and fifth-wheel or gooseneck tongue weight should be 15–25% of the total loaded trailer weight (2). Some specific trailer types, such as boat trailers, fall outside of this range. Always refer to the trailer owner’s manual for the recommended trailer tongue weight for each trailer. Never exceed the maximum loads for the vehicle, hitch, and trailer. The trailer load balance percentage is calculated as: weight (1) divided by weight (2) times 100. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating After loading the trailer, separately weigh the trailer and then the trailer tongue and calculate the trailer load balance percentage to see if the weights and distribution are appropriate for your vehicle. If the trailer weight is too high, it may be possible to transfer some of the cargo into your vehicle. If the trailer tongue weight is too high or too low, it may be possible to rearrange some of the cargo inside of the trailer. Do not exceed the maximum allowable tongue weight for your vehicle. Use the shortest hitch extension available to position the hitch ball closer to your vehicle. This will help reduce the effect of the trailer tongue weight on the trailer hitch and the rear axle. Rear Gross Axle Weight Rating (GAWR-RR) The GAWR-RR is the total weight that can be supported by the rear axle of the vehicle. Do not exceed the GAWR-RR for the vehicle, with the tow vehicle and trailer fully loaded for the trip including the weight of the trailer tongue. If using a weight-distributing hitch, do not exceed the GAWR-RR before applying the weight distribution spring bars. 281 Towing Equipment Hitches { Warning In order to avoid serious injury or property damage, always follow the hitch manufacturer's instructions when securing your draw bar/coupling device to the vehicle's hitch receiver. Ensure that the draw bar/coupling device is secured with a locking retainer pin or other means such that rotation of the pin or locking mechanism will not cause the pin to back out or loosen during use. Failure to correctly secure the draw bar/ coupling device to the receiver can result in separation of the hitch/receiver while towing. If a cargo carrier is used in the trailer hitch receiver, choose a carrier that positions the load as close to the vehicle as possible. Make sure the total weight, including the carrier, is no more than half of the maximum allowable tongue weight for the vehicle or 227 kg (500 lb), whichever is less. The GAWR-RR for the vehicle is on the Trailering Information Label. Ask your dealer for trailering information or assistance. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 282 Driving and Operating Conventional Hitch A conventional hitch is bolted to the frame or cross member of the tow vehicle, and is generally rated Class 2, 3, or 4. Gooseneck Hitch A gooseneck hitch is designed to be coupled to a special hitch leveraging a hitch ball, and is mounted over the rear axle in the truck bed. Fifth-Wheel Hitch A fifth-wheel hitch is mounted over the rear axle in the truck bed, and leverages a hinged plate — the same type of hitch leveraged by semi trucks. Generally, fifth-wheel hitches accommodate large trailers with as many as one, two, or three axles. Always use the correct hitch equipment for your vehicle. Crosswinds, large trucks going by, and rough roads can affect the trailer and the hitch. Avoid sharp turns when using a step-bumper hitch to prevent damage. Make wider turns to prevent contact between your trailer and your bumper. Proper hitch equipment for your vehicle helps maintain control of the vehicle-trailer combination. Many trailers can be towed using a weight-carrying hitch which has a coupler latched to the hitch ball, or a tow eye latched to a pintle hook. Other trailers may require a weight-distributing hitch that uses spring bars to distribute the trailer tongue weight between your vehicle and trailer axles. Fifth-wheel and gooseneck hitches may also be used. See “Maximum Trailer Tongue Weight” under Trailer Towing 0 278 for weight limits with various hitch types. Consider using mechanical sway controls with any trailer. Ask a trailering professional about sway controls or refer to the trailer manufacturer's recommendations and instructions. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating 283 Weight-Distributing Hitch and Adjustment A weight-distributing hitch may be useful with some trailers. Use the following guidelines to determine if a weight-distributing hitch should be used.

Weight distributing hitch optional for other vehicles. 1. Front of Vehicle 2. H1/H2 Body to Ground Distance Towing with Model 2500/3500 Trucks 1. Position the truck so that the trailer is ready to connect. Keep the trailer detached. 2. Measure the height of the top of the front wheel opening at the fender to the ground (H1). 3. Attach the vehicle to the trailer. Do not attach weight distribution bars at this time. 4. Measure the height of the top of the front wheel opening on the fender to the ground (H2). 5. Install and adjust the tension in the weight-distributing bars per the manufacturers’ recommendations so that the height of the front fender is approximately H2−[(H2−H1)/4] (1/4 the difference between the two measured ride heights, below the secondary ride height {H2}). 6. Visually inspect the trailer and weight-distributing hitch to ensure that the manufacturers’ recommendations have been met. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

Do not tow a trailer while using a compact spare tire on the vehicle. . Tires must be properly inflated to support loads while towing a trailer. See Tires 0 344 for instructions on proper tire inflation. Fifth-Wheel and Gooseneck Trailering Fifth-wheel and gooseneck trailers can be used with many pickup models. These trailers place a larger percentage of the weight (kingpin weight) on the tow vehicle than conventional trailers. Make sure this weight does not cause the vehicle to exceed GAWR or GVWR. Fifth-wheel or gooseneck kingpin weight should be 15–25% of the trailer weight up to the maximum amount specified in the trailering chart for the vehicle. See “Trailer Weight" under Trailer Towing 0 278. Two Inch Adapter Sleeve and Retainer Pin The hitch should be in the pickup bed so that its centerline is over or slightly in front of the rear axle. Take care that it is not so far forward that it will contact the back of the cab in sharp turns. This is especially important for short box pickups. Trailer pin box extensions and sliding fifth-wheel hitch assemblies may be used. There should be at least 15 cm (6 in) of clearance between the top of the pickup box and the bottom of the trailer shelf that extends over the box. Safety Chains Make sure the hitch is attached to the tow vehicle frame rails. Do not use the pickup box for support. The 2500/3500 series vehicles are equipped with a 2-1/2” square receiver. An adapter is provided to allow the use of a 2” draw bar, along with a hitch retainer pin, and retainer clip. Always attach safety chains between the vehicle and the trailer. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. If the trailer being towed weighs up to 2 271 kg (5,000 lb) with a factory-installed step bumper, safety chains may be attached Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

If you do, both the vehicle antilock brakes and the trailer brakes may not function, which could result in a crash. frame. The harness requires the installation of a trailer connector, which is available through your dealer. Cross the safety chains under the tongue of the trailer to help prevent the tongue from contacting the road if it becomes separated from the hitch. Always leave enough slack in the safety chains to allow the combination to turn. Never allow safety chains to drag on the ground. Auxiliary Battery Use only a round, seven-wire connector with flat blade terminals meeting SAE J2863 specifications for proper electrical connectivity. Trailer Brakes Loaded trailers over 900 kg (2,000 lb) must be equipped with brake systems and with brakes for each axle. Trailer braking equipment conforming to Canadian Standards Association (CSA) requirement CAN3-D313, or its equivalent, is recommended. State or local regulations may require trailers to have their own braking system if the loaded weight of the trailer exceeds certain minimums that can vary from state to state. Read and follow the instructions for the trailer brakes so they are installed, adjusted, and maintained properly. Never attempt to tap into your vehicle's hydraulic If equipped, the vehicle's auxiliary battery can be used to supply electrical power to additional equipment that may be added, such as a slide-in camper. Locate the auxiliary battery connector under the hood on the driver side of the vehicle, next to the engine compartment fuse block. Follow the proper installation instructions included with any electrical equipment that is installed. Caution To prevent draining the auxiliary battery, always turn off electrical equipment when not in use and do not use any equipment that may exceed the maximum amperage rating of 30 amps.

When the camper-wiring harness is ordered without the heavy-duty trailering package, a seven-wire harness with a seven-pin connector is at the rear of the vehicle and is tied to the vehicle's frame. Trailer Lamps Always check that all trailer lamps are working at the beginning of each trip, and periodically on longer trips. If equipped, the Trailering App will monitor the RH turn/brake lamp circuit, LH turn/ brake lamp circuit, running lamp circuit, and reverse lamp circuits on the trailer. DIC messages and Trailering App alerts may be displayed if lighting circuit issues are detected on the trailer. 287 Pressing START LIGHT TEST in the Trailering App automatically activates the trailer lamps. The Trailering App is not a substitute for manually inspecting your trailer lamps. See Trailering App 0 292. Turn Signals When Towing a Trailer When properly connected, the trailer turn signals will illuminate to indicate the vehicle is turning, changing lanes, or stopping. When towing a trailer, the arrows on the instrument cluster will illuminate even if the trailer is not properly connected or the bulbs are burned out. Tow/Haul Mode For instructions on how to enter Tow/Haul Mode, see Driver Mode Control 0 249. Tow/Haul assists when pulling a heavy trailer or a large or heavy load. See Tow/ Haul Mode 0 240. Tow/Haul Mode is designed to be most effective when the vehicle and trailer combined weight is at least 75% of the vehicle's Gross Combined Weight Rating (GCWR). See “Trailer Weight” under Trailer Towing 0 278. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 288 Driving and Operating Tow/Haul Mode is most useful when towing a heavy trailer or carrying a large or heavy load: . Through rolling terrain. . In stop-and-go traffic. . In busy parking lots. This symbol is on the Trailer Brake Control Panel on vehicles with an ITBC system. The power output to the trailer brakes is proportional to the amount of vehicle braking. This available power output to the trailer brakes can be adjusted to a wide range of trailering situations. Operating the vehicle in Tow/Haul Mode when lightly loaded or not towing will not cause damage; however, it is not recommended and may result in unpleasant engine and transmission driving characteristics, heavy or light steering efforts, and reduced fuel economy. The ITBC system is integrated with the vehicle’s brake, antilock brake, and StabiliTrak/Electronic Stability Control (ESC) systems. In trailering conditions that cause the vehicle’s antilock brake or StabiliTrak/ ESC systems to activate, power sent to the trailer's brakes will be automatically adjusted to minimize trailer wheel lock-up. This does not imply that the trailer has StabiliTrak/ESC. Integrated Trailer Brake Control System The vehicle may have an Integrated Trailer Brake Control (ITBC) system for use with electric trailer brakes or most electric over hydraulic trailer brake systems. These instructions apply to both types of electric trailer brakes. { Warning Connecting a trailer that has an air brake system may result in reduced or complete loss of trailer braking, including increased stopping distance or trailer instability which could result in serious injury, death, or property damage. Only use the ITBC system with electric or electric over hydraulic trailer brake systems. Trailer Brake Control Panel If the vehicle’s brake, antilock brake, or StabiliTrak/ESC systems are not functioning properly, the ITBC system may not function fully or at all. Make sure all of these systems are fully operational to allow the ITBC system to function properly. The ITBC system is powered through the vehicle's electrical system. Turning the ignition off will also turn off the ITBC system. The ITBC system is fully functional only when the ignition is in on. 1. Manual Trailer Brake Apply Lever 2. Trailer Symbol 3.

When traffic conditions allow, carefully pull the vehicle over to the side of the road and turn the ignition off. Check the wiring connection to the trailer and turn the ignition back on. If either of these messages continues, either the vehicle or trailer needs service. A GM dealer may be able to diagnose and repair problems with the trailer. However, any diagnosis and repair of the trailer is not covered under the vehicle warranty. Contact your trailer dealer for assistance with trailer repairs and trailer warranty information. Trailer Sway Control (TSC) Vehicles with StabiliTrak/Electronic Stability Control (ESC) have a Trailer Sway Control (TSC) feature. Trailer sway is unintended side-to-side motion of a trailer while towing. If the vehicle is towing a trailer and the TSC detects that sway is increasing, the vehicle brakes are selectively applied at each wheel, to help reduce excessive trailer sway. If equipped with the Integrated Trailer Brake Control (ITBC) system, and the trailer has an electric brake system, StabiliTrak/ESC may also apply the trailer brakes. If TSC is enabled, the Traction Control System (TCS)/StabiliTrak/ESC warning light will flash on the instrument cluster. Reduce vehicle speed by gradually removing your foot from the accelerator. If trailer sway continues, StabiliTrak/ESC can reduce engine torque to help slow the vehicle. TSC will not function if StabiliTrak/ESC is turned off. See Traction Control/Electronic Stability Control 0 247. 291 { Warning Trailer sway can result in a crash and in serious injury or death, even if the vehicle is equipped with TSC. If the trailer begins to sway, reduce vehicle speed by gradually removing your foot from the accelerator. Then pull over to check the trailer and vehicle to help correct possible causes, including an improperly or overloaded trailer, unrestrained cargo, improper trailer hitch configuration, or improperly inflated or incorrect vehicle or trailer tires. See Towing Equipment 0 281 for trailer ratings and hitch setup recommendations. Aftermarket Electronic Trailer Sway Control Devices Some trailers may come equipped with an electronic device designed to reduce or control trailer sway. Aftermarket equipment manufacturers also offer similar devices that connect to the wiring between the trailer and the vehicle. These devices may interfere with the vehicle’s trailer brake or other systems, including integrated anti-sway systems, if equipped.

The effects of these aftermarket devices may have on vehicle handling or trailer brake performance is not known. { Warning Use of aftermarket electronic trailer sway control devices could result in reduced trailer brake performance, loss of trailer brakes, or other malfunctions, and result in a crash. You or others could be seriously injured or killed. Before using one of these devices: . Ask the device or trailer manufacturer if the device has been thoroughly tested for compatibility with the make, model, and year of your vehicle and any optional equipment installed on your vehicle. . Before driving, check the trailer brakes are working properly, if equipped. Drive the vehicle with the trailer attached on a level road surface that is free of traffic at about 32-40 km/h (20-25 mph) and fully apply the (Continued) Warning (Continued) manual trailer brake apply lever. Also, check the trailer brake lamps and other lamps are functioning correctly. . If the trailer brakes are not operating properly at any time, or if a DIC message indicates problems with the trailer connections or trailer brakes, carefully pull the vehicle over to the side of the road when traffic conditions allow. If the vehicle is equipped with a trailer tire pressure monitoring system, see the trailer tire pressure monitoring system description and the trailering app. Trailer tires deteriorate over time. The trailer tire sidewall will show the week and year the tire was manufactured. Many trailer tire manufacturers recommend replacing tires more than six years old. Trailer Tires Overloading is another leading cause of trailer tire blow-outs. Never load your trailer with more weight than the tires are designed to support. The load rating is located on the trailer tire sidewall. Special Trailer (ST) tires differ from vehicle tires. Trailer tires are designed with stiff sidewalls to help prevent sway and to support heavy loads. These features can make it difficult to determine if the trailer tire pressures are low only based on a visual inspection. Always know the maximum speed rating for the trailer tires before driving. This may be significantly lower than the vehicle tire speed rating. The speed rating may be on the trailer tire sidewall. If the speed rating is not shown, the default trailer tire speed rating is 105 km/h (65 mph). Always check all trailer tire pressures before each trip when the tires are cool. Low trailer tire pressure is a leading cause of trailer tire blow-outs.

Conversions and Add-Ons Add-On Electrical Equipment { Warning The Data Link Connector (DLC) is used for vehicle service and Emission Inspection/ Maintenance testing. See Malfunction Indicator Lamp (Check Engine Light) 0 116. A device connected to the DLC — such as an aftermarket fleet or driver-behavior tracking device — may interfere with vehicle systems. This could affect vehicle operation and cause a crash. Such devices may also access information stored in the vehicle’s systems. Caution Some electrical equipment can damage the vehicle or cause components to not work and would not be covered by the vehicle warranty. Always check with your dealer before adding electrical equipment. Add-on equipment can drain the vehicle's 12-volt battery, even if the vehicle is not operating. 303 The vehicle has an airbag system. Before attempting to add anything electrical to the vehicle, see Servicing the Airbag-Equipped Vehicle 0 71 and Adding Equipment to the Airbag-Equipped Vehicle 0 71.

Adding a Snow Plow or Similar Equipment Caution Do not exceed 72 km/h (45 mph) with a snow plow mounted to the vehicle. The vehicle could overheat and be damaged. Before installing a snow plow on the vehicle, follow these guidelines: Caution If the vehicle does not have the snow plow prep package, RPO VYU, adding a plow can damage the vehicle, and the repairs would not be covered by the vehicle warranty. Unless the vehicle was built to carry a snow plow, do not add (Continued) Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 304 Driving and Operating Caution (Continued) one to the vehicle. If the vehicle has RPO VYU, then the payload the vehicle can carry will be reduced when a snow plow is installed. The vehicle can be damaged if either the front or rear axle ratings or the Gross Vehicle Weight Rating (GVWR) are exceeded. The plow the vehicle can carry depends on many things, such as: . The options the vehicle came with, and the weight of those options. . The weight and number of passengers to be carried. . The weight of items added to the vehicle, like a tool box or truck cap. . The total weight of any additional cargo to be carried. To safely carry a snow plow on the vehicle: . With a snow plow attached, the engine coolant temperature gauge may show a higher temperature than while driving without one. The snow plow could block the airflow to the radiator. This could be more noticeable as vehicle speed increases. At speeds above 72 km/h (45 mph), this may cause the engine . . . . . coolant to overheat. Move or angle the snow plow blade to allow increased airflow to the radiator. To increase the airflow, move the snow plow blade position. If driving more than 24 km/h (15 mi), angle the plow blade position. Make sure the weight on the front and rear axles does not exceed the axle rating for each. Follow the snowplow manufacturer’s recommendations for any rear ballast that may be required. Rear ballast may be required to ensure a proper front and rear weight distribution ratio even though the actual weight at the front axle may be less than the front axel rating. The snowplow manufacturer or installer can assist in determining the amount of rear ballast required to ensure that the vehicle with the attached snowplow does not exceed the GVW rating, the front and rear axle ratings, or the front and rear weight distribution ratio. Front axle reserve capacity is the difference between the Front Gross Axle Weight Rating (GAWR) and the front axle weight of the vehicle with full fuel, passengers, and any other cargo. This is the amount of weight that can be added to the front axle before reaching the Front GAWR. To calculate the amount of weight any front accessory, such as a snow plow, is adding to the front axle, use this formula: (W x (A + W.B.)) /W.B.= Weight the accessory is adding to the front axle. Where: IW = Weight of added accessory IA = Distance that the accessory is in front of the front axle IW.B. = Vehicle Wheelbase Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Driving and Operating For example, adding a 318 kg (700 lb) snow plow actually adds more than 318 kg (700 lb) to the front axle. Using the formula, if the snow plow is 122 cm (4 ft) in front of the front axle and the wheelbase is 305 cm (10 ft), then: IW = 318 kg (700 lb) IA = 122 cm (4 ft) IW.B. = 305 cm (10 ft) (W x (A + W.B.)/W.B. = (318 x (122 + 305))/305 = 445 kg (980 lb) This means if the front axle reserve capacity is more than 445 kg (980 lb), the snow plow could be added without exceeding the front GAWR. Heavier equipment can be added on the front of the vehicle if less cargo or fewer passengers are carried, or by positioning cargo toward the rear. This reduces the load on the front. However, the front GAWR, rear GAWR, and Gross Vehicle Weight Rating (GVWR) must never be exceeded. { Warning On some vehicles that have certain front mounted equipment, such as a snow plow, it may be possible to load the front axle to the front Gross Axle Weight Rating (GAWR) but not have enough weight on the rear axle to have proper braking performance. If the brakes cannot work properly, the vehice could crash. Always follow the snow plow manufacturer or installer's recommendation for rear ballast to ensure a proper front and rear weight distribution ratio. Maintaining a proper front and rear weight distribution ratio is necessary to provide proper braking performance. See your dealer for additional advice and information about using a snow plow on the vehicle. Also, see Vehicle Load Limits 0 220. 305 Pickup Conversion to Chassis Cab We are aware that some vehicle owners might consider having the pickup box removed and a commercial or recreational body installed. Owners should be aware that, as manufactured, there are differences between a chassis cab and a pickup with the box removed which could affect vehicle safety. The components necessary to adapt a pickup to permit its safe use with a specialized body should be installed by the body builder. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

If the vehicle has a diesel engine, see the Duramax diesel supplement. Engine Oil For diesel engine vehicles, see “Engine Oil” in the Duramax diesel supplement. To ensure proper engine performance and long life, careful attention must be paid to engine oil. Following these simple, but important steps will help protect your investment: . Use engine oil approved to the proper specification and of the proper viscosity grade. See “Selecting the Right Engine Oil” in this section. . Check the engine oil level regularly and maintain the proper oil level. See “Checking Engine Oil” and “When to Add Engine Oil” in this section. . Change the engine oil at the appropriate time. See Engine Oil Life System 0 313. . Always dispose of engine oil properly. See “What to Do with Used Oil” in this section. Checking Engine Oil Check the engine oil level regularly, every 650 km (400 mi), especially prior to a long trip. The engine oil dipstick handle is a loop. See Engine Compartment Overview 0 310 for the location. 311 { Warning The engine oil dipstick handle may be hot; it could burn you. Use a towel or glove to touch the dipstick handle. If a low oil Driver Information Center (DIC) message displays, check the oil level. Follow these guidelines: . To get an accurate reading, park the vehicle on level ground. Check the engine oil level after the engine has been off for at least two hours. Checking the engine oil level on steep grades or too soon after engine shutoff can result in incorrect readings. Accuracy improves when checking a cold engine prior to starting. Remove the dipstick and check the level. . If unable to wait two hours, the engine must be off for at least 15 minutes if the engine is warm, or at least 30 minutes if the engine is not warm. Pull out the dipstick, wipe it with a clean paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down, and check the level. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 312 Vehicle Care When to Add Engine Oil Caution (Continued) damaged. Drain the excess oil or limit driving of the vehicle, and seek a service professional to remove the excess oil. See Engine Compartment Overview 0 310 for the location of the engine oil fill cap. If the oil is below the cross-hatched area at the tip of the dipstick and the engine has been off for at least 15 minutes, add 1 L (1 qt) of the recommended oil and then recheck the level. See “Selecting the Right Engine Oil” later in this section for an explanation of what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications 0 406. Add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when through. Selecting the Right Engine Oil Selecting the right engine oil depends on both the proper oil specification and viscosity grade. See Recommended Fluids and Lubricants 0 401. Specification Caution Do not add too much oil. Oil levels above or below the acceptable operating range shown on the dipstick are harmful to the engine. If the oil level is above the operating range (i.e., the engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range), the engine could be (Continued) Use full synthetic engine oils that meet the dexos1 specification. Engine oils that have been approved by GM as meeting the dexos1 specification are marked with the dexos1 approved logo. Caution Failure to use the recommended engine oil or equivalent can result in engine damage not covered by the vehicle warranty. Viscosity Grade Use SAE 5W-30 viscosity grade engine oil. Cold Temperature Operation: In an area of extreme cold, where the temperature falls below −29 °C (−20 °F), use SAE 0W-30 oil. An oil of this viscosity grade will provide easier cold starting for the engine at extremely low temperatures. When selecting an oil of the appropriate viscosity grade, it is recommended to select an oil of the correct specification. See “Specification” earlier in this section. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Vehicle Care Engine Oil Additives/Engine Oil Flushes Engine Oil Life System Do not add anything to the oil. The recommended oils meeting the dexos1 specification are all that is needed for good performance and engine protection. When to Change Engine Oil Engine oil system flushes are not recommended and could cause engine damage not covered by the vehicle warranty. What to Do with Used Oil Used engine oil contains certain elements that can be unhealthy for your skin and could even cause cancer. Do not let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine oil. See the manufacturer's warnings about the use and disposal of oil products. Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil by putting it in the trash or pouring it on the ground, into sewers, or into streams or bodies of water. Recycle it by taking it to a place that collects used oil. This vehicle has a computer system that indicates when to change the engine oil and filter. This is based on a combination of factors which include engine revolutions, engine temperature, and miles driven. Based on driving conditions, the mileage at which an oil change is indicated can vary considerably. For the oil life system to work properly, the system must be reset every time the oil is changed. On some vehicles, when the system has calculated that oil life has been diminished, a CHANGE ENGINE OIL SOON message comes on to indicate that an oil change is necessary. Change the oil as soon as possible within the next 1 000 km (600 mi). It is possible that, if driving under the best conditions, the oil life system might indicate that an oil change is not necessary for up to a year. The engine oil and filter must be changed at least once a year and, at this time, the system must be reset. For vehicles without the CHANGE ENGINE OIL SOON message, an oil change is needed when the REMAINING OIL LIFE percentage is near 0%. Your dealer has trained service people who 313 will perform this work and reset the system. It is also important to check the oil regularly over the course of an oil drain interval and keep it at the proper level. If the system is ever reset accidentally, the oil must be changed at 5 000 km (3,000 mi) since the last oil change. Remember to reset the oil life system whenever the oil is changed. How to Reset the Engine Oil Life System Reset the system whenever the engine oil is changed so that the system can calculate the next engine oil change. Always reset the engine oil life to 100% after every oil change. It will not reset itself. To reset the engine oil life system: 1. Display the oil life percentage on the DIC. See Driver Information Center (DIC) (Base Level) 0 124 or Driver Information Center (DIC) (Midlevel and Uplevel) 0 125. 2. Press the thumbwheel on the steering wheel, or the trip odometer reset stem if the vehicle does not have DIC controls, for several seconds. When the confirmation message displays, select YES. The oil life will change to 100%. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 314 Vehicle Care The oil life system can also be reset as follows: 1. Display the oil life percentage on the DIC. See Driver Information Center (DIC) (Base Level) 0 124 or Driver Information Center (DIC) (Midlevel and Uplevel) 0 125. 2. Fully press the accelerator pedal slowly three times within five seconds. 3. If the display changes to 100%, the system is reset. If the vehicle has a CHANGE ENGINE OIL SOON message and it comes back on when the vehicle is started and/or the oil life percentage is near 0%, the engine oil life system has not been reset. Repeat the procedure. Automatic Transmission Fluid When to Check and Change Automatic Transmission Fluid It is usually not necessary to check the transmission fluid level. The only reason for fluid loss is a transmission leak or overheated transmission. This vehicle is not equipped with a transmission fluid level dipstick. There is a special procedure for checking and changing the transmission fluid in these vehicles. Because this procedure is difficult, this should be done at the dealer. Contact the dealer for additional information or the procedure can be found in the service manual. See Publication Ordering Information 0 416. Caution Use of the incorrect automatic transmission fluid may damage the vehicle, and the damage may not be covered by the vehicle warranty. Always use the correct automatic transmission fluid. See Recommended Fluids and Lubricants 0 401. Change the fluid and filter at the scheduled maintenance intervals listed in Maintenance Schedule 0 392. Be sure to use the transmission fluid listed in Recommended Fluids and Lubricants 0 401. Engine Air Filter Life System If equipped, this feature provides the engine air filter’s remaining life and best timing for a change. The timing to change an engine air filter depends on driving and environmental conditions. When to Change the Engine Air Filter When the Driver Information Center (DIC) displays a message to replace the engine air filter at the next oil change, follow this timing. When the DIC displays a message to replace the engine air filter soon, replace the engine air filter at the earliest convenience. The system must be reset after the engine air filter is changed. If the DIC displays a message to check the engine air filter system, see your dealer. How to Reset the Engine Air Filter Life System To reset: 1. Place the vehicle in P (Park). 2.

Caution Do not use anything other than a mix of DEX-COOL coolant that meets GM Standard GMW3420 and clean, drinkable water. Anything else can cause damage to the engine cooling system and the vehicle, which would not be covered by the vehicle warranty. Checking Coolant The coolant surge tank is in the engine compartment on the driver side of the vehicle. See Engine Compartment Overview 0 310. How to Add Coolant to the Coolant Surge Tank If the vehicle has a diesel engine, see “Cooling System” in the Duramax diesel supplement for the proper coolant fill procedure. temperature. Never dispose of engine coolant by putting it in the trash, or by pouring it on the ground, or into sewers, streams, or bodies of water. Have the coolant changed by an authorized service center, familiar with legal requirements regarding used coolant disposal. This will help protect the environment and your health. 317 { Warning Spilling coolant on hot engine parts can burn you. Coolant contains ethylene glycol and it will burn if the engine parts are hot enough. Check to see if coolant is visible in the coolant surge tank. If the coolant inside the coolant surge tank is boiling, wait until it cools down. The coolant level should be at or above the indicated mark. If it is not, there may be a leak in the cooling system. If coolant is visible but the coolant level is not at or above the indicated mark, see the following sections on how to add coolant to the coolant surge tank following. { Warning Plain water, or other liquids such as alcohol, can boil before the proper coolant mixture will. With plain water or the wrong mixture, the engine could get too hot but there would not be an overheat warning. The engine could catch fire and you or others could be burned. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 318 Vehicle Care { Warning Steam and scalding liquids from a hot cooling system are under pressure. Turning the pressure cap, even a little, can cause them to come out at high speed and you could be burned. Never turn the cap when the cooling system, including the pressure cap, is hot. Wait for the cooling system and pressure cap to cool. Caution Failure to follow the specific coolant fill procedure could cause the engine to overheat and could cause system damage. If coolant is not visible in the surge tank, contact your dealer. If no coolant is visible in the surge tank, add coolant. 1. Remove the coolant surge tank pressure cap when the cooling system, including the coolant surge tank pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise about one full turn. If a hiss is heard, wait for that to stop. A hiss means there is still some pressure left. 2. Keep turning the pressure cap slowly, and remove it. 3. Fill the coolant surge tank with the proper mixture to the full cold mark. 4. With the coolant surge tank pressure cap off, start the engine and let it run until the engine coolant temperature gauge indicates approximately 90 °C (195 °F). By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper mixture to the coolant surge tank until the level reaches the indicated mark. 5. Replace the pressure cap tightly. 6. Verify coolant level after the engine is shut off and the coolant is cold. If necessary, repeat coolant fill procedure Steps 1–6. Caution If the pressure cap is not tightly installed, coolant loss and engine damage may occur. Be sure the cap is properly and tightly secured. Engine Overheating If the vehicle has the Duramax diesel engine, see the Duramax diesel supplement. Caution Do not run the engine if there is a leak in the engine cooling system. This can cause a loss of all coolant and can damage the system and vehicle. Have any leaks fixed right away. The vehicle has several indicators to warn of engine overheating. There is a coolant temperature gauge in the vehicle's instrument cluster. See Engine Coolant Temperature Gauge 0 113. In addition, there are ENGINE OVERHEATED STOP ENGINE, ENGINE OVERHEATED IDLE ENGINE, and ENGINE POWER IS REDUCED messages in the Driver Information Center (DIC). Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Vehicle Care If the decision is made not to lift the hood when this warning appears, get service help right away. See Roadside Assistance Program 0 412. If the decision is made to lift the hood, make sure the vehicle is parked on a level surface. Check to see if the engine cooling fans are running. If the engine is overheating, the fans should be running. If they are not, do not continue to run the engine and have the vehicle serviced. If the engine or transmission detects an impending hot fluid condition, then the transmission may force upshifts to limit temperatures. Downshifts may also be prevented in this instance. Normal operation may continue unless the display indicates there is a hot condition and engine should be idled. If Steam is Coming from the Engine Compartment { Warning Steam and scalding liquids from a hot cooling system are under pressure. Turning the pressure cap, even a little, can cause them to come out at high speed and you could be burned. Never turn the cap when the cooling system, including the pressure cap, is hot. Wait for the cooling system and pressure cap to cool. If No Steam is Coming from the Engine Compartment The ENGINE OVERHEATED STOP ENGINE or the ENGINE OVERHEATED IDLE ENGINE message, along with a low coolant condition, can indicate a serious problem. If there is an engine overheat warning, but no steam is seen or heard, the problem may not be too serious. Sometimes the engine can get a little too hot when the vehicle: . Climbs a long hill on a hot day. . Stops after high-speed driving. . Idles for long periods in traffic. 319 . Tows a trailer; see Trailer Towing 0 278. If the ENGINE OVERHEATED STOP ENGINE or the ENGINE OVERHEATED IDLE ENGINE message appears with no sign of steam, try this for a minute or so: 1. Turn the air conditioning off. 2. Turn the heater on to the highest temperature and to the highest fan speed. Open the windows as necessary. 3. When it is safe to do so, pull off the road, shift to P (Park) or N (Neutral) and let the engine idle. If the temperature overheat gauge is no longer in the overheat zone or an overheat warning no longer displays, the vehicle can be driven. Continue to drive the vehicle slowly for about 10 minutes. Keep a safe vehicle distance from the vehicle in front. If the warning does not come back on, continue to drive normally and have the cooling system checked for proper fill and function. If the warning continues, pull over, stop, and park the vehicle right away. If there is still no sign of steam and the vehicle is equipped with an engine driven cooling fan, push down the accelerator until the engine speed is about twice as fast as Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 320 Vehicle Care normal idle speed for at least five minutes while the vehicle is parked. If the warning is still there, turn off the engine and get everyone out of the vehicle until it cools down. may continue unless the display indicates there is a hot condition and engine should be idled. If there is no sign of steam, idle the engine for five minutes while parked. If the warning is still displayed, turn off the engine until it cools down. After driving in the overheated engine protection operating mode, the engine oil will be severely degraded. Any repairs performed before the engine is cool may cause engine damage. Allow the engine to cool before attempting any repair. Repair the cause of coolant loss, change the oil, and reset the oil life system. See Engine Oil 0 311. Overheated Engine Protection Operating Mode If an overheated engine condition exists and the ENGINE POWER IS REDUCED message displays, an overheat protection mode which alternates firing groups of cylinders helps to prevent engine damage. In this mode, a loss in power and engine performance will be noticed. This operating mode allows the vehicle to be driven to a safe place in an emergency. Driving extended distances and/ or towing a trailer in the overheat protection mode should be avoided. If the engine or transmission detects an impending hot fluid condition, then the transmission may force upshifts to limit temperatures. Downshifts may also be prevented in this instance. Normal operation Caution so an increase in fan noise may be heard. This is normal and should not be mistaken as the transmission slipping or making extra shifts. It is merely the cooling system functioning properly. The fan will slow down when additional cooling is not required and the clutch partially disengages. This fan noise may be heard when starting the engine. It will go away as the fan clutch partially disengages. Power Steering Fluid Engine Fan If the vehicle has the Duramax diesel engine, see the Duramax diesel supplement. The vehicle has a clutched engine cooling fan. When the clutch is engaged, the fan spins faster to provide more air to cool the engine. In most everyday driving conditions, the fan is spinning slower and the clutch is not fully engaged. This improves fuel economy and reduces fan noise. Under heavy vehicle loading, trailer towing, and/or high outside temperatures, the fan speed increases as the clutch more fully engages, The power steering fluid reservoir is in the engine compartment on the driver side of the vehicle. See Engine Compartment Overview 0 310 for reservoir location. When to Check Power Steering Fluid It is not necessary to regularly check power steering fluid unless there is a leak suspected in the system or an unusual noise Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Vehicle Care is heard. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. Wait for the power steering system to cool, with the engine off, before checking the fluid. How to Check Power Steering Fluid To check the power steering fluid: 1. Set the ignition off and let the engine compartment cool down. 2. Wipe the cap and the top of the reservoir clean. 3. Unscrew the cap and wipe the dipstick with a clean rag. 4. Replace the cap and completely tighten it. 5. Remove the cap again and look at the fluid level on the dipstick. The level should be between the ADD and FULL marks. If necessary, add only enough fluid to bring the level up to the hashed area between the ADD and FULL marks, do not overfill. To prevent contamination of brake fluid, never check or fill the power steering reservoir with the brake master cylinder cover off. What to Use Caution Use of the incorrect fluid may damage the vehicle and the damages may not be covered by the vehicle warranty. Always use the correct fluid listed in Recommended Fluids and Lubricants 0 401. To determine what kind of fluid to use, see Recommended Fluids and Lubricants 0 401. Always use the proper fluid. Failure to use the proper fluid can cause leaks and damage hoses and seals. Washer Fluid What to Use When windshield washer fluid needs to be added, be sure to read the manufacturer's instructions before use. Use a fluid that has sufficient protection against freezing in an area where the temperature may fall below freezing. 321 Adding Washer Fluid The vehicle has a low washer fluid message on the DIC that comes on when the washer fluid is low. The message is displayed for 15 seconds at the start of each ignition cycle. When the WASHER FLUID LOW ADD FLUID message displays, washer fluid will need to be added to the windshield washer fluid reservoir. Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview 0 310 for reservoir location. Caution . Do not use washer fluid that contains any type of water repellent coating. This can cause the wiper blades to chatter or skip. (Continued) Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 322 Vehicle Care Caution (Continued) . Do not use engine coolant (antifreeze) in the windshield washer. It can damage the windshield washer system and paint. . Do not mix water with ready-to-use washer fluid. Water can cause the solution to freeze and damage the washer fluid tank and other parts of the washer system. . When using concentrated washer fluid, follow the manufacturer instructions for adding water. . Fill the washer fluid tank only three-quarters full when it is very cold. This allows for fluid expansion if freezing occurs, which could damage the tank if it is completely full. Brakes Disc brake linings have built-in wear indicators that make a high-pitched warning sound when the brake linings are worn and new linings are needed. The sound can come and go or can be heard all the time when the vehicle is moving, except when applying the brake pedal firmly. { Warning The brake wear warning sound means that soon the brakes will not work well. That could lead to a crash. When the brake wear warning sound is heard, have the vehicle serviced. Caution Continuing to drive with worn-out brake linings could result in costly brake repairs. Some driving conditions or climates can cause a brake squeal when the brakes are first applied, clearing up following several applications. This does not mean something is wrong with the brakes. Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake linings for wear and evenly tighten wheel nuts in the proper sequence to torque specifications. See Capacities and Specifications 0 406. Brake pads should be replaced as complete axle sets. Brake Pedal Travel See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign that brake service may be required. Replacing Brake System Parts Always replace brake system parts with new, approved replacement parts. If this is not done, the brakes may not work properly. The braking performance can change in many ways if the wrong brake parts are installed or if parts are improperly installed. Brake Pad Life System When to Change Brake Pads This vehicle has a system that estimates the remaining life of the front and rear brake pads. Brake pad life is displayed in the Driver Information Center (DIC), along with a percentage for each axle. The system must be reset every time the brake pads are changed. When the system has determined that the brake pads need to be replaced, a message will display, which may include mileage remaining. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Vehicle Care Brake pads should always be replaced as complete axle sets. How to Reset the Brake Pad Life System The system will automatically detect when significantly worn brake pads are replaced. When the ignition is turned on after new pads and wear sensors are installed, a message will display. Follow the prompts to reset the system. The brake pad life system can also be manually reset: 1. Display Brake Pad Life on the DIC. See Driver Information Center (DIC) (Base Level) 0 124 or Driver Information Center (DIC) (Midlevel and Uplevel) 0 125. 2. Select the Brake Pad Life menu. 3. Select front or rear pads as appropriate. 4. Select YES on the confirmation message. Repeat for pads on the other axle if they were also replaced. How to Disable the Brake Pad Life System The brake pad life system can be turned off. This may be necessary if aftermarket brake pads without wear sensors are installed. When the system is turned off, the front and rear brake pad life percentages will not display. However, the built-in wear indicators that make a high-pitched warning sound when the brake pads are worn can still determine when the pads should be replaced. See Brakes 0 322. To turn off the brake pad life system: 1. Display Brake Pad Life on the DIC. See Driver Information Center (DIC) (Base Level) 0 124 or Driver Information Center (DIC) (Midlevel and Uplevel) 0 125. 2. Select the Brake Pad Life menu. 3. Select DISABLE. To turn the brake pad life system back on, follow the above steps but select ENABLE in Step 2. Brake Fluid 323 The brake master cylinder reservoir is filled with GM approved DOT 4 brake fluid as indicated on the reservoir cap. See Engine Compartment Overview 0 310 for the location of the reservoir. Checking Brake Fluid With the vehicle in P (Park) on a level surface, the brake fluid level should be between the minimum and maximum marks on the brake fluid reservoir. There are only two reasons why the brake fluid level in the reservoir may go down: . Normal brake lining wear. When new linings are installed, the fluid level goes back up. . A fluid leak in the brake hydraulic system. Have the brake hydraulic system fixed. With a leak, the brakes will not work well. Always clean the brake fluid reservoir cap and the area around the cap before removing it. Do not top off the brake fluid. Adding fluid does not correct a leak. If fluid is added when the linings are worn, there will be too much fluid when new brake linings are Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 324 Vehicle Care installed. Add or remove fluid, as necessary, only when work is done on the brake hydraulic system. { Warning If too much brake fluid is added, it can spill on the engine and burn, if the engine is hot enough. You or others could be burned, and the vehicle could be damaged. Add brake fluid only when work is done on the brake hydraulic system. When the brake fluid falls to a low level, the brake warning light comes on. See Brake System Warning Light 0 117. Brake fluid absorbs water over time which degrades the effectiveness of the brake fluid. Replace brake fluid at the specified intervals to prevent increased stopping distance. See Maintenance Schedule 0 392. What to Add Use only GM approved DOT 4 brake fluid from a clean, sealed container. See Recommended Fluids and Lubricants 0 401. { Warning The wrong or contaminated brake fluid could result in damage to the brake system. This could result in the loss of braking leading to a possible injury. Always use the proper GM approved brake fluid. Caution If brake fluid is spilled on the vehicle's painted surfaces, the paint finish can be damaged. Immediately wash off any painted surface.

Electrical System Electrical System Overload License Plate Lamp The vehicle has fuses and circuit breakers to protect against an electrical system overload. To replace the bulb: 1. Reach behind the rear bumper and locate the bulb. 2. Turn the bulb socket counterclockwise and pull the bulb straight out of the socket. When the current electrical load is too heavy, the circuit breaker opens and closes, protecting the circuit until the current load returns to normal or the problem is fixed. This greatly reduces the chance of circuit overload and fire caused by electrical problems. To check a fuse, look at the band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a fuse of the identical size and rating. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Vehicle Care 335 4. If the fuse must be replaced immediately, spare fuses are also provided on the instrument panel end cap or borrow a replacement fuse with the same amperage from the fuse block. Choose a vehicle feature that is not needed to safely operate the vehicle. Repeat Steps 2-3. 5. Insert the replacement fuse into the empty slot of the blown fuse. At the next opportunity, see your dealer to replace the blown fuse. Replacing a Blown Fuse Headlamp Wiring 1. Turn off the vehicle. 2. Locate the fuse puller on the instrument panel end cap. See the Instrument Panel Fuse Block (Right) 0 341 or Instrument Panel Fuse Block (Left) 0 339. An electrical overload may cause the lamps to go on and off, or in some cases to remain off. Have the headlamp wiring checked right away if the lamps go on and off or remain off. Windshield Wipers If the wiper motor overheats due to heavy snow or ice, the windshield wipers will stop until the motor cools and will then restart. 3. Use the fuse puller to remove the fuse from the top or side, as shown above. Although the circuit is protected from electrical overload, overload due to heavy snow or ice may cause wiper linkage Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

Underinflated tires pose the same danger as overloaded tires. The resulting crash could cause serious injury. Check all tires frequently to . (Continued) . . maintain the recommended pressure. Tire pressure should be checked when the tires are cold. Overinflated tires are more likely to be cut, punctured, or broken by a sudden impact — such as when hitting a pothole. Keep tires at the recommended pressure. Worn or old tires can cause a crash. If the tread is badly worn, replace them. Replace any tires that have been damaged by impacts with potholes, curbs, etc. Improperly repaired tires can cause a crash. Only your dealer or an authorized tire service center should repair, replace, dismount, and mount the tires. (Continued) . Warning (Continued) Do not spin the tires in excess of 56 km/h (35 mph) on slippery surfaces such as snow, mud, ice, etc. Excessive spinning may cause the tires to explode. All-Season Tires This vehicle may come with all-season tires. These tires are designed to provide good overall performance on most road surfaces and weather conditions. Original equipment tires designed to GM's specific tire performance criteria have a TPC specification code molded onto the sidewall. Original equipment all-season tires can be identified by the last two characters of this TPC code, which will be “MS.” Consider installing winter tires on the vehicle if frequent driving on snow or ice-covered roads is expected. All-season tires provide adequate performance for most winter driving conditions, but they may not offer the same level of traction or performance as winter tires on snow or ice-covered roads. See Winter Tires 0 345. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Vehicle Care Winter Tires All-Terrain Tires This vehicle was not originally equipped with winter tires. Winter tires are designed for increased traction on snow and ice-covered roads. Consider installing winter tires on the vehicle if frequent driving on ice or snow covered roads is expected. See your dealer for details regarding winter tire availability and proper tire selection. Also, see Buying New Tires 0 359. This vehicle may have all-terrain or mud-terrain tires. These tires provide good performance on most road surfaces, weather conditions, and for off-road driving. See Off-Road Driving 0 214. With winter tires, there may be decreased dry road traction, increased road noise, and shorter tread life. After changing to winter tires, be alert for changes in vehicle handling and braking. If using winter tires: . Use tires of the same brand and tread type on all four wheel positions. . Use only radial ply tires of the same size, load range, and speed rating as the original equipment tires. Winter tires with the same speed rating as the original equipment tires may not be available for H, V, W, Y, and ZR speed rated tires. If winter tires with a lower speed rating are chosen, never exceed the tire's maximum speed capability. The tread pattern on these tires may wear more unevenly than other tires. Consider rotating the tires more frequently than at 12 000 km (7,500 mi) intervals if irregular wear is noted when the tires are inspected. See Tire Inspection 0 355.

Tire Pressure Tires need the correct amount of air pressure to operate effectively. { Warning Neither tire underinflation nor overinflation is good. Underinflated tires, or tires that do not have enough air, can result in: . Tire overloading and overheating, which could lead to a blowout. . Premature or irregular wear. . Poor handling. . Reduced fuel economy. Overinflated tires, or tires that have too much air, can result in: . Unusual wear. . Poor handling. . Rough ride. . Needless damage from road hazards. 349 The Tire and Loading Information label on the vehicle indicates the original equipment tires and the correct cold tire inflation pressures. The recommended pressure is the minimum air pressure needed to support the vehicle's maximum load carrying capacity. For additional information regarding how much weight the vehicle can carry, and an example of the Tire and Loading Information label, see Vehicle Load Limits 0 220. How the vehicle is loaded affects vehicle handling and ride comfort. Never load the vehicle with more weight than it was designed to carry. When to Check Check the pressure of the tires once a month or more. Do not forget the spare tire, if the vehicle has one. See Full-Size Spare Tire 0 374 for additional information. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 350 Vehicle Care How to Check Use a good quality pocket-type gauge to check tire pressure. Proper tire inflation cannot be determined by looking at the tire. Check the tire inflation pressure when the tires are cold, meaning the vehicle has not been driven for at least three hours or no more than 1.6 km (1 mi). Remove the valve cap from the tire valve stem. Press the tire gauge firmly onto the valve to get a pressure measurement. If the cold tire inflation pressure matches the recommended pressure on the Tire and Loading Information label, no further adjustment is necessary. If the inflation pressure is low, add air until the recommended pressure is reached. If the inflation pressure is high, press on the metal stem in the center of the tire valve to release air. Re-check the tire pressure with the tire gauge. Put the valve caps back on the valve stems to keep out dirt and moisture. Use only valve caps designed for the vehicle by GM. TPMS sensors could be damaged and would not be covered by the vehicle warranty. Tire Pressure Monitor System The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check tire pressure levels. The TPMS sensors monitor the air pressure in your tires and transmit tire pressure readings to a receiver located in the vehicle. Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Vehicle Care sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly. See Tire Pressure Monitor Operation 0 351. See Radio Frequency Statement 0 417. Tire Pressure Monitor Operation This vehicle may have a Tire Pressure Monitor System (TPMS). The TPMS is designed to warn the driver when a low tire pressure condition exists. TPMS sensors are mounted onto each tire and wheel assembly, excluding the spare tire and wheel assembly. The TPMS sensors monitor the air pressure in the tires and transmit the tire pressure readings to a receiver located in the vehicle. When a low tire pressure condition is detected, the TPMS illuminates the low tire pressure warning light located on the instrument cluster. If the warning light comes on, stop as soon as possible and inflate the tires to the recommended pressure shown on the Tire and Loading Information label. See Vehicle Load Limits 0 220. A message to check the pressure in a specific tire displays in the Driver Information Center (DIC). The low tire pressure warning light and the DIC warning message come on at each ignition cycle until the tires are inflated to the correct inflation pressure. If the vehicle has DIC buttons, tire pressure levels can be viewed. For additional information and details about the DIC operation and displays, 351 see Driver Information Center (DIC) (Base Level) 0 124 or Driver Information Center (DIC) (Midlevel and Uplevel) 0 125. The low tire pressure warning light may come on in cool weather when the vehicle is first started, and then turn off as the vehicle is driven. This could be an early indicator that the air pressure is getting low and needs to be inflated to the proper pressure. A Tire and Loading Information label shows the size of the original equipment tires and the correct inflation pressure for the tires when they are cold. See Vehicle Load Limits 0 220, for an example of the Tire and Loading Information label and its location. Also see Tire Pressure 0 349. The TPMS can warn about a low tire pressure condition but it does not replace normal tire maintenance. See Tire Inspection 0 355, Tire Rotation 0 356 and Tires 0 344. Caution Tire sealant materials are not all the same. A non-approved tire sealant could damage the TPMS sensors. TPMS sensor (Continued) Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 352 Vehicle Care Caution (Continued) damage caused by using an incorrect tire sealant is not covered by the vehicle warranty. Always use only the GM approved tire sealant available through your dealer or included in the vehicle. TPMS Malfunction Light and Message The TPMS will not function properly if one or more of the TPMS sensors are missing or inoperable. When the system detects a malfunction, the low tire pressure warning light flashes for about one minute and then stays on for the remainder of the ignition cycle. A DIC warning message also displays. The malfunction light and DIC warning message come on at each ignition cycle until the problem is corrected. Some of the conditions that can cause these to come on are: . One of the road tires has been replaced with the spare tire. The spare tire does not have a TPMS sensor. The malfunction light and the DIC message should go off after the road tire is replaced and the sensor matching process is performed successfully. See "TPMS Sensor Matching Process" later in this section. . The TPMS sensor matching process was not done or not completed successfully after rotating the tires. The malfunction light and the DIC message should go off after successfully completing the sensor matching process. See "TPMS Sensor Matching Process" later in this section. . One or more TPMS sensors are missing or damaged. The malfunction light and the DIC message should go off when the TPMS sensors are installed and the sensor matching process is performed successfully. See your dealer for service. . Replacement tires or wheels do not match the original equipment tires or wheels. Tires and wheels other than those recommended could prevent the TPMS from functioning properly. See Buying New Tires 0 359. . Operating electronic devices or being near facilities using radio wave frequencies similar to the TPMS could cause the TPMS sensors to malfunction. If the TPMS is not functioning properly, it cannot detect or signal a low tire pressure condition. See your dealer for service if the TPMS malfunction light and DIC message come on and stay on. Tire Fill Alert (If Equipped) This feature provides visual and audible alerts outside the vehicle to help when inflating an underinflated tire to the recommended cold tire pressure. When the low tire pressure warning light comes on: 1. Park the vehicle in a safe, level place. 2. Set the parking brake firmly. 3. Place the vehicle in P (Park). 4. Add air to the tire that is underinflated. The turn signal lamp will flash. When the recommended pressure is reached, the horn sounds once and the turn signal lamp will stop flashing and briefly turn solid. Repeat these steps for all underinflated tires that have illuminated the low tire pressure warning light. { Warning Overinflating a tire could cause the tire to rupture and you or others could be injured. Do not exceed the maximum (Continued) Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Vehicle Care Warning (Continued) pressure listed on the tire sidewall. See Tire Sidewall Labeling 0 345 and Vehicle Load Limits 0 220. If the tire is overinflated by more than 35 kPa (5 psi), the horn will sound multiple times and the turn signal lamp will continue to flash for several seconds after filling stops. To release and correct the pressure, while the turn signal lamp is still flashing, briefly press the center of the valve stem. When the recommended pressure is reached, the horn sounds once. If the turn signal lamp does not flash within 15 seconds after starting to inflate the tire, the tire fill alert has not been activated or is not working. If the hazard warning flashers are on, the tire fill alert visual feedback will not work properly. The TPMS will not activate the tire fill alert properly under the following conditions: . There is interference from an external device or transmitter. . The air pressure from the inflation device is not sufficient to inflate the tire. . There is a malfunction in the TPMS. . There is a malfunction in the horn or turn signal lamps. . The identification code of the TPMS sensor is not registered to the system. . The battery of the TPMS sensor is low. If the tire fill alert does not operate due to TPMS interference, move the vehicle about 1 m (3 ft) back or forward and try again. If the tire fill alert feature is not working, use a tire pressure gauge. TPMS Sensor Matching Process Each TPMS sensor has a unique identification code. The identification code needs to be matched to a new tire/wheel position after rotating the vehicle’s tires or replacing one or more of the TPMS sensors. Also, the TPMS sensor matching process should be performed after replacing a spare tire with a road tire containing the TPMS sensor. The malfunction light and the DIC message should go off at the next ignition cycle. The sensors are matched to the tire/ wheel positions, using a TPMS relearn tool, in the following order: driver side front tire, passenger side front tire, passenger side rear tire, and driver side rear. See your dealer for service or to purchase a relearn tool. 353 A TPMS relearn tool can also be purchased. See Tire Pressure Monitor Sensor Activation Tool at www.gmtoolsandequipment.com or call 1-800-GM TOOLS (1-800-468-6657). There are two minutes to match the first tire/wheel position, and five minutes overall to match all four tire/wheel positions. If it takes longer, the matching process stops and must be restarted. The TPMS sensor matching process is: 1. Set the parking brake. 2. Turn the ignition on without starting the vehicle. 3. Uplevel DIC Only: Make sure the Tire Pressure info page option is turned on. The info pages on the DIC can be turned on and off through the Options menu. See Driver Information Center (DIC) (Base Level) 0 124 or Driver Information Center (DIC) (Midlevel and Uplevel) 0 125. 4. If the vehicle has an uplevel DIC, use the DIC controls on the right side of the steering wheel to scroll to the Tire Pressure screen under the DIC info page. If the vehicle has a base level DIC, use the trip odometer reset stem to scroll to the Tire Pressure screen. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 354 Vehicle Care 5. If the vehicle has an uplevel DIC, press and hold the thumbwheel located in the center of the DIC controls on the right side of the steering wheel. If the vehicle has a base level DIC, press and hold the trip odometer reset stem for about five seconds. A message asking if the process should begin should appear. Select yes and press the trip odometer reset stem to confirm the selection. The horn sounds twice to signal the receiver is in relearn mode and the TIRE LEARNING ACTIVE message displays on the DIC screen. 6. Start with the driver side front tire. 7. Place the relearn tool against the tire sidewall, near the valve stem. Then press the button to activate the TPMS sensor. A horn chirp confirms that the sensor identification code has been matched to this tire and wheel position. 8. Proceed to the passenger side front tire, and repeat the procedure in Step 7. 9. Proceed to the passenger side rear tire, and repeat the procedure in Step 7. 10. Proceed to the driver side rear tire, and repeat the procedure in Step 7. The horn sounds two times to indicate the sensor identification code has been matched to the driver side rear tire, and the TPMS sensor matching process is no longer active. The TIRE LEARNING ACTIVE message on the DIC display screen goes off. 11. Turn the vehicle off. 12. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading Information label. Trailer Tire Pressure Monitoring Operation If equipped, the Trailer Tire Pressure Monitoring System (TTPMS) is designed to monitor the pressure of the trailer tires and warn the driver when a low pressure condition exists. TTPMS sensors for four tires are provided. The system can accommodate a trailer with up to six tires if additional sensors are purchased from the dealer. Also, the system can be paired with up to five individual trailers. Prior to use, the vehicle must learn the sensors by following the learning process. See Trailering App 0 292. Contact your trailer service center or tire service center to have the pressure sensors installed inside the trailer tires. The technician should insert the sensor stem through the hole in the trailer wheel. When the sensor is correctly positioned, the nut on the sensor stem should be tightened to 8 Y (6 lb ft). When mounting the trailer tire onto the trailer wheel be careful not to damage the sensor. The Trailering App can be used to view the tire pressures after the recommended trailer tire pressures have been entered. Refer to the trailer tire placard on the trailer or the trailer tire sidewall for the recommended tire pressure. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Vehicle Care The system is compatible with trailer tires that have placard pressure values from 103 689 kpa (15 - 100 psi). The hole in the wheel for the tire stem must be 11.43 mm (0.453 in) or 15.88 mm (0.625 in) in diameter. Use of the pressure sensors on a wheel with a different stem hole size could result in loss of air from the tire. If a low trailer tire pressure condition is detected, the TTPMS displays a warning message on the DIC. If the warning message is displayed, stop as soon as possible and inflate the tires to the recommended pressure shown on the tire placard on the trailer. In addition, the TTPMS monitors the temperature of the trailer tires. If the system detects a high temperature on one or more of the trailer tires, a warning message will be displayed on the DIC. If this warning message is displayed, stop as soon as possible, and inspect the overheated trailer tire. Common causes for high trailer tire temperature are underinflation, overloading, or tire damage. TTPMS Malfunction Message The TTPMS will not function properly if one or more of the trailer tire sensors are missing or inoperable. If the system detects a malfunction, a DIC message indicates that the system requires service. Some of the conditions that can cause the service message to occur are: . One of the trailer tires has been replaced with the spare tire which does not have a learned TTPMS sensor. The DIC message should turn off after the pressure sensor is installed in the tire, and the learning process is performed successfully. See "TTPMS Sensor Learning Process" under Trailering App 0 292. . The TTPMS sensor learning process was not done or not completed successfully. The DIC message should go off after successfully completing the sensor learning process. See "TTPMS Sensor Learning Process" under Trailering App 0 292. . One or more TTPMS sensors are missing or damaged. The DIC message should go off when the TTPMS sensors are installed and the sensor learning process is 355 performed successfully. See "TTPMS Sensor Learning Process" under Trailering App 0 292. . Operating electronic devices or being near facilities using radio wave frequencies similar to the TTPMS could cause interference to the TTPMS which could cause loss of signal reception from the sensor. . If the system does not receive the signal from an individual sensor, an error message may not occur until the vehicle has been driver for a period of time. If the TTPMS is not functioning properly, it cannot detect or signal a low tire condition. See your dealer for service if the DIC message comes on and stays on when the trailer tire pressures have been checked and determined to be correct. Tire Inspection We recommend that the tires, including the spare tire, if the vehicle has one, be inspected for signs of wear or damage at least once a month. Replace the tire if: . The indicators at three or more places around the tire can be seen. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 356 Vehicle Care There is cord or fabric showing through the tire's rubber. . The tread or sidewall is cracked, cut, or snagged deep enough to show cord or fabric. . The tire has a bump, bulge, or split. . The tire has a puncture, cut, or other damage that cannot be repaired well because of the size or location of the damage. . See When It Is Time for New Tires 0 358 and Wheel Replacement 0 361. If the full-size spare tire is part of the tire rotation, make sure the tire rotated into the spare position is stored securely. Push, pull, and then try to rotate or turn the tire. If it moves, use the wheel wrench/hoist shaft to tighten the cable. See Tire Changing 0 364. Tire Rotation Tires should be rotated every 12 000 km (7,500 mi). See Maintenance Schedule 0 392. Tires are rotated to achieve a more uniform wear for all tires. The first rotation is the most important. Anytime unusual wear is noticed, rotate the tires as soon as possible, check for proper tire inflation pressure, and check for damaged tires or wheels. If the unusual wear continues after the rotation, check the wheel alignment. Use this rotation pattern when rotating the tires if the vehicle has single rear wheels. Dual Tire Rotation When the vehicle is new, or whenever a wheel, wheel bolt, or wheel nut is replaced or serviced, check the wheel nut torque after 160, 1 600, and 10 000 km (100, 1,000, and 6,000 mi) of driving. For proper torque and wheel nut tightening information, see “Removing the Flat Tire and Installing the Spare Tire” under Tire Changing 0 364 and “Wheel Nut Torque” under Capacities and Specifications 0 406 and “Removing the Flat Tire and Installing the Spare Tire” under Tire Changing 0 364. The outer tire on a dual wheel setup generally wears faster than the inner tire. Tires last longer and wear more evenly if they are rotated. See Tire Inspection 0 355 and Tire Rotation 0 356. Also see Maintenance Schedule 0 392. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Vehicle Care 357 Adjust the front and rear tires to the recommended inflation pressure on the Tire and Loading Information label after the tires have been rotated. See Tire Pressure 0 349 and Vehicle Load Limits 0 220. Reset the Tire Pressure Monitor System. See Tire Pressure Monitor Operation 0 351. Use this rotation pattern when rotating the tires if the vehicle has dual rear wheels (except polished forged aluminum wheels). Vehicles with polished forged aluminum dual wheels have three unique wheels; a front, a rear outer and a rear inner. These wheels cannot be rotated to another position, however, they can be rotated from left to right to the same position. Use this rotation pattern when rotating the tires if the vehicle has polished forged aluminum dual rear wheels. The spare wheel can be used in any position in the event of a flat tire, and can be rotated with the rear inner wheels. After the flat tire is repaired, if the spare is not on one of the inner rear positions, it must be replaced by the correct wheel in the front or rear outer positions. When installing dual wheels, check that the vent holes in the inner and outer wheels on each side are lined up. Check that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Specifications 0 406, and “Removing the Flat Tire and Installing the Spare Tire” under Tire Changing 0 364. { Warning Rust or dirt on a wheel, or on the parts to which it is fastened, can cause wheel nuts to become loose over time. The wheel could come off and cause a crash. When changing a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle.

The last four digits of the TIN indicate the tire manufactured date. The first two digits represent the week and the last two digits, the year. For example, the third week of the year 2020 would have a 4-digit DOT date of 0320. Week 01 is the first full week (Sunday through Saturday) of each year. Warning (Continued) or paper towel can be used; however, use a scraper or wire brush later to remove all rust or dirt. Lightly coat the inner diameter of the wheel hub opening with wheel bearing grease after a wheel change or tire rotation to prevent corrosion or rust build-up. { Warning Do not apply grease to the wheel mounting surface, wheel conical seats, or the wheel nuts or bolts. Grease applied to these areas could cause a wheel to become loose or come off, resulting in a crash. When It Is Time for New Tires Factors, such as maintenance, temperatures, driving speeds, vehicle loading, and road conditions affect the wear rate of the tires. Vehicle Storage Treadwear indicators are one way to tell when it is time for new tires. Treadwear indicators appear when the tires have only 1.6 mm (1/16 in) or less of tread remaining. See Tire Inspection 0 355 and Tire Rotation 0 356 for additional information. The rubber in tires ages over time. This also applies to the spare tire, if the vehicle has one, even if it is never used. Multiple factors including temperatures, loading conditions, and inflation pressure maintenance affect how fast aging takes place. GM recommends that tires, including the spare if equipped, be replaced after six years, regardless of tread wear. To identify the age of a tire, use the tire manufacture date, which is the last Tires age when stored normally mounted on a parked vehicle. Park a vehicle that will be stored for at least a month in a cool, dry, clean area away from direct sunlight to slow aging. This area should be free of grease, gasoline, or other substances that can deteriorate rubber. Parking for an extended period can cause flat spots on the tires that may result in vibrations while driving. When storing a vehicle for at least a month, remove the tires or raise the vehicle to reduce the weight from the tires. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Vehicle Care Buying New Tires GM has developed and matched specific tires for the vehicle. The original equipment tires installed were designed to meet General Motors Tire Performance Criteria Specification (TPC Spec) system rating. When replacement tires are needed, GM strongly recommends buying tires with the same TPC Spec rating. GM's exclusive TPC Spec system considers over a dozen critical specifications that impact the overall performance of the vehicle, including brake system performance, ride and handling, traction control, and tire pressure monitoring performance. GM's TPC Spec number is molded onto the tire's sidewall near the tire size. If the tires have an all-season tread design, the TPC Spec number will be followed by MS for mud and snow. See Tire Sidewall Labeling 0 345 for additional information. GM recommends replacing worn tires in complete sets of four (six for dual rear wheels). Uniform tread depth on all tires will help to maintain the performance of the vehicle. Braking and handling performance may be adversely affected if all the tires are not replaced at the same time. If proper rotation and maintenance have been done, all four tires (six for dual rear wheels) should wear out at about the same time. However, if it is necessary to replace only one axle set of worn tires, place the new tires on the rear axle (two for single rear wheels, four for dual rear wheels). See Tire Rotation 0 356. { Warning Tires could explode during improper service. Attempting to mount or dismount a tire could cause injury or death. Only your dealer or authorized tire service center should mount or dismount the tires. 359 { Warning Mixing tires of different sizes (other than those originally installed on the vehicle), brands, tread patterns, or types may cause loss of vehicle control, resulting in a crash or other vehicle damage. Use the correct size, brand, and type of tire on all wheels. { Warning Using bias-ply tires on the vehicle may cause the wheel rim flanges to develop cracks after many miles of driving. A tire and/or wheel could fail suddenly and cause a crash. Use only radial-ply tires with the wheels on the vehicle. Winter tires with the same speed rating as the original equipment tires may not be available for H, V, W, Y and ZR speed rated tires. Never exceed the winter tires’ maximum speed capability when using winter tires with a lower speed rating. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 360 Vehicle Care If the vehicle tires must be replaced with a tire that does not have a TPC Spec number, make sure they are the same size, load range, speed rating, and construction (radial) as the original tires. The Tire and Loading Information label indicates the original equipment tires on the vehicle. See Vehicle Load Limits 0 220. Different Size Tires and Wheels If wheels or tires are installed that are a different size than the original equipment wheels and tires, vehicle performance, including its braking, ride and handling characteristics, stability, and resistance to rollover may be affected. If the vehicle has electronic systems such as antilock brakes, rollover airbags, traction control, electronic stability control, or All-Wheel Drive, the performance of these systems can also be affected. { Warning If different sized wheels are used, there may not be an acceptable level of performance and safety if tires not recommended for those wheels are selected. This increases the chance of a crash and serious injury. Only use GM specific wheel and tire systems developed for the vehicle, and have them properly installed by a GM certified technician. See Buying New Tires 0 359 and Accessories and Modifications 0 307. Uniform Tire Quality Grading The following information relates to the system developed by the United States National Highway Traffic Safety Administration (NHTSA), which grades tires by treadwear, traction, and temperature performance. This applies only to vehicles sold in the United States. The grades are molded on the sidewalls of most passenger car tires. The Uniform Tire Quality Grading (UTQG) system does not apply to deep tread, winter tires, compact spare tires, tires with nominal rim diameters of 10 to 12 inches (25 to 30 cm), or to some limited-production tires. While the tires available on General Motors passenger cars and light trucks may vary with respect to these grades, they must also conform to federal safety requirements and additional General Motors Tire Performance Criteria (TPC) standards. Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: Treadwear 200 Traction AA Temperature A All Passenger Car Tires Must Conform to Federal Safety Requirements In Addition To These Grades. Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one-half (1½) Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Vehicle Care times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate. Traction The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics. Temperature The temperature grades are A (the highest), B, and C, representing the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. Warning: The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure. 361 Wheel Alignment and Tire Balance The tires and wheels were aligned and balanced at the factory to provide the longest tire life and best overall performance. Adjustments to wheel alignment and tire balancing are not necessary on a regular basis. Consider an alignment check if there is unusual tire wear or the vehicle is significantly pulling to one side or the other. Some slight pull to the left or right, depending on the crown of the road and/or other road surface variations such as troughs or ruts, is normal. If the vehicle is vibrating when driving on a smooth road, the tires and wheels may need to be rebalanced. See your dealer for proper diagnosis. Wheel Replacement Replace any wheel that is bent, cracked, or badly rusted or corroded. If wheel nuts keep coming loose, the wheel, wheel bolts, and wheel nuts should be replaced. If the wheel leaks air, replace it. Some aluminum wheels can be repaired. See your dealer if any of these conditions exist. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 362 Vehicle Care Your dealer will know the kind of wheel that is needed. Each new wheel should have the same load-carrying capacity, diameter, width, offset, and be mounted the same way as the one it replaces. Replace wheels, wheel bolts, wheel nuts, or Tire Pressure Monitor System (TPMS) sensors with new GM original equipment parts. { Warning Using the wrong replacement wheels, wheel bolts, or wheel nuts can be dangerous. It could affect the braking and handling of the vehicle. Tires can lose air, and cause loss of control, causing a crash. Always use the correct wheel, wheel bolts, and wheel nuts for replacement. Caution The wrong wheel can also cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height, vehicle ground clearance, and tire or tire chain clearance to the body and chassis. Used Replacement Wheels { Warning Replacing a wheel with a used one is dangerous. How it has been used or how far it has been driven may be unknown. It could fail suddenly and cause a crash. When replacing wheels, use a new GM original equipment wheel. Tire Chains { Warning If the vehicle has LT275/65R20 size tires, do not use tire chains. There is not enough clearance. Tire chains used on a vehicle without the proper amount of clearance can cause damage to the brakes, suspension, or other vehicle parts. The area damaged by the tire chains could cause loss of control and a crash. Use another type of traction device only if its manufacturer recommends it for the vehicle's tire size combination and road conditions. Follow that manufacturer's instructions. To avoid vehicle damage, drive slow and readjust or remove the (Continued) Warning (Continued) traction device if it is contacting the vehicle. Do not spin the wheels. If traction devices are used, install them on the rear tires. Caution Use tire chains only where legal and only when necessary. Use chains that are the proper size for the tires. If the vehicle has LT235/80R17 size tires, install the chains on the tires of the rear axle only. If the vehicle has LT245/75R17, LT265/70R17, or LT275/70R18 size tires, install the chains on the tires of the front and rear axle. Tighten them as tightly as possible with the ends securely fastened. Drive slowly and follow the chain manufacturer's instructions. If the chains contact the vehicle, stop and retighten them. If the contact continues, slow down until it stops. Driving too fast or spinning the wheels with chains on will damage the vehicle. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Vehicle Care If a Tire Goes Flat It is unusual for a tire to blowout while driving, especially if the tires are maintained properly. If air goes out of a tire, it is much more likely to leak out slowly. But if there ever is a blowout, here are a few tips about what to expect and what to do: If a front tire fails, the flat tire creates a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel firmly. Steer to maintain lane position, and then gently brake to a stop, well off the road, if possible. A rear blowout, particularly on a curve, acts much like a skid and may require the same correction as used in a skid. Stop pressing the accelerator pedal and steer to straighten the vehicle. It may be very bumpy and noisy. Gently brake to a stop, well off the road, if possible. { Warning Driving on a flat tire will cause permanent damage to the tire. Re-inflating a tire after it has been driven on while severely underinflated or flat (Continued) 363 Warning (Continued) { Warning may cause a blowout and a serious crash. Never attempt to re-inflate a tire that has been driven on while severely underinflated or flat. Have your dealer or an authorized tire service center repair or replace the flat tire as soon as possible. Changing a tire can be dangerous. The vehicle can slip off the jack and roll over or fall causing injury or death. Find a level place to change the tire. To help prevent the vehicle from moving: 1. Set the parking brake firmly. 2. Shift the vehicle to P (Park). { Warning Lifting a vehicle and getting under it to do maintenance or repairs is dangerous without the appropriate safety equipment and training. If a jack is provided with the vehicle, it is designed only for changing a flat tire. If it is used for anything else, you or others could be badly injured or killed if the vehicle slips off the jack. If a jack is provided with the vehicle, only use it for changing a flat tire. If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place, well off the road, if possible. Turn on the hazard warning flashers. See Hazard Warning Flashers 0 142. 3. For vehicles with four-wheel drive with an N (Neutral) transfer case position, be sure the transfer case is in a drive gear — not in N (Neutral). 4. Turn off the engine and do not restart while the vehicle is raised. 5. Do not allow passengers to remain in the vehicle. 6. Place wheel blocks, if equipped, on both sides of the tire at the opposite corner of the tire being changed.

Normally, any concerns with the sales transaction or the operation of the vehicle will be resolved by your dealer's sales or service departments. Sometimes, however, despite the best intentions of all concerned, misunderstandings can occur. If your concern has not been resolved to your satisfaction, the following steps should be taken: STEP ONE : Discuss your concern with a member of dealership management. Normally, concerns can be quickly resolved at that level. If the matter has already been reviewed with the sales, service, or parts manager, contact the owner of your dealership or the general manager. STEP TWO : If after contacting a member of dealership management, it appears your concern cannot be resolved by your dealership without further help, in the U.S., call the Chevrolet Customer Assistance Center at 1-800-222-1020. In Canada, call General Motors of Canada Customer Care Centre at 1-800-263-3777 (English), or 1-800-263-7854 (French). Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 410 Customer Information We encourage you to call the toll-free number in order to give your inquiry prompt attention. Have the following information available to give the Customer Assistance representative: . Vehicle Identification Number (VIN). This is available from the vehicle registration or title, or the plate at the top left of the instrument panel and visible through the windshield. . Dealership name and location. . Vehicle delivery date and present mileage. When contacting Chevrolet, remember that your concern will likely be resolved at a dealer's facility. That is why we suggest following Step One first. STEP THREE — U.S. Owners : Both General Motors and your dealer are committed to making sure you are completely satisfied with your new vehicle. However, if you continue to remain unsatisfied after following the procedure outlined in Steps One and Two, you can file with the Better Business Bureau (BBB) AUTO LINE Program to enforce your rights. The BBB AUTO LINE Program is an out-of-court program administered by BBB National Programs, Inc. to settle automotive disputes regarding vehicle repairs or the interpretation of the New Vehicle Limited Warranty. Although you may be required to resort to this informal dispute resolution program prior to filing a court action, use of the program is free of charge and your case will generally be heard within 40 days. If you do not agree with the decision given in your case, you may reject it and proceed with any other venue for relief available to you. General Motors reserves the right to change eligibility limitations and/or discontinue its participation in this program. Telephone: 1-800-955-5100 http://www.bbb.org/council/ programs-services/ dispute-handling-and-resolution/bbb-auto-line STEP THREE — Canadian Owners : In the event that you do not feel your concerns have been addressed after following the procedure outlined in Steps One and Two, General Motors of Canada Company wants you to be aware of its participation in a no-charge Mediation/Arbitration Program. General Motors of Canada Company has committed to binding arbitration of owner disputes involving factory-related vehicle service claims. The program provides for the review of the facts involved by an impartial third party arbiter, and may include an informal hearing before the arbiter. The program is designed so that the entire dispute settlement process, from the time you file your complaint to the final decision, should be completed in about 70 days. We believe our impartial program offers advantages over courts in most jurisdictions because it is informal, quick, and free of charge. This program is available in all 50 states and the District of Columbia. Eligibility is limited by vehicle age, mileage, and other factors. For further information concerning eligibility in the Canadian Motor Vehicle Arbitration Plan (CAMVAP), call toll-free 1-800-207-0685, You may contact the BBB AUTO LINE Program using the toll-free telephone number or write them at the following address: BBB AUTO LINE a Division of BBB National Programs, Inc. 1676 International Drive Suite 550 McLean, VA 22102 Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 414 Customer Information Scheduling Service Appointments When the vehicle requires warranty service, contact your dealer and request an appointment. By scheduling a service appointment and advising the service consultant of your transportation needs, your dealer can help minimize your inconvenience. If the vehicle cannot be scheduled into the service department immediately, keep driving it until it can be scheduled for service, unless, of course, the problem is safety related. If it is, please call your dealership, let them know this, and ask for instructions. If your dealer requests you to bring the vehicle for service, you are urged to do so as early in the work day as possible to allow for same-day repair. Courtesy Transportation Program To enhance your ownership experience, we and our participating dealers are proud to offer Courtesy Transportation, a customer support program for vehicles with the Bumper-to-Bumper (Base Warranty Coverage period in Canada), Federal Emission, Extended Powertrain or Electric specific warranties in both the U.S. and Canada. Several Courtesy Transportation options are available to assist in reducing inconvenience when warranty repairs are required. Courtesy Transportation is not a part of the New Vehicle Limited Warranty. A separate manual entitled “Limited Warranty and Owner Assistance Information” furnished with each new vehicle provides detailed warranty coverage information. Transportation Options Warranty service can generally be completed while you wait. However, if you are unable to do so, your dealer may offer the following transportation options: Shuttle Service This includes one-way or round-trip shuttle service within reasonable time and distance parameters of your dealer's area. Public Transportation or Fuel Reimbursement If overnight warranty repairs are needed, and public transportation is used, the expense must be supported by original receipts and within the maximum amount allowed by GM. If U.S. customers arrange their own transportation, limited reimbursement for reasonable fuel expenses may be available. Claim amounts should reflect actual costs and be supported by original receipts. See your dealer for information. Courtesy Rental Vehicle For an overnight warranty repair, the dealer may provide an available courtesy rental vehicle or provide for reimbursement of a rental vehicle. Reimbursement is limited and must be supported by original receipts as well as a signed and completed rental agreement and meet state/provincial, local, and rental vehicle provider requirements. Requirements vary and may include minimum age requirements, insurance coverage, credit card, etc. Additional fees such as fuel, rental vehicle insurance, taxes, levies, usage fees, excessive mileage, or rental usage beyond the completion of the repair are also your responsibility.

Collision Damage Repair If the vehicle is involved in a collision and it is damaged, have the damage repaired by a qualified technician using the proper equipment and quality replacement parts. Poorly performed collision repairs diminish the vehicle resale value, and safety performance can be compromised in subsequent collisions. Collision Parts Genuine GM Collision parts are new parts made with the same materials and construction methods as the parts with which the vehicle was originally built. Genuine GM Collision parts are the best choice to ensure that the vehicle's designed appearance, durability, and safety are preserved. The use of Genuine GM parts can help maintain the GM New Vehicle Limited Warranty. Recycled original equipment parts may also be used for repair. These parts are typically removed from vehicles that were total losses in prior crashes. In most cases, the parts being recycled are from undamaged sections of the vehicle. A recycled original equipment GM part may be an acceptable choice to maintain the vehicle's originally designed appearance and safety performance; however, the history of these parts is not known. Such parts are not covered by the GM New Vehicle Limited Warranty, and any related failures are not covered by that warranty. Aftermarket collision parts are also available. These are made by companies other than GM and may not have been tested for the vehicle. As a result, these parts may fit poorly, exhibit premature durability/ corrosion problems, and may not perform properly in subsequent collisions. Aftermarket parts are not covered by the GM New Vehicle Limited Warranty, and any vehicle failure related to such parts is not covered by that warranty. Repair Facility GM also recommends that you choose a collision repair facility that meets your needs before you ever need collision repairs. 415 Your dealer may have a collision repair center with GM-trained technicians and state-of-the-art equipment, or be able to recommend a collision repair center that has GM-trained technicians and comparable equipment. Insuring the Vehicle Protect your investment in the GM vehicle with comprehensive and collision insurance coverage. There are significant differences in the quality of coverage afforded by various insurance policy terms. Many insurance policies provide reduced protection to the GM vehicle by limiting compensation for damage repairs through the use of aftermarket collision parts. Some insurance companies will not specify aftermarket collision parts. When purchasing insurance, we recommend that you ensure that the vehicle will be repaired with GM original equipment collision parts. If such insurance coverage is not available from your current insurance carrier, consider switching to another insurance carrier. If the vehicle is leased, the leasing company may require you to have insurance that ensures repairs with Genuine GM Original Equipment Manufacturer (OEM) parts or Genuine Manufacturer replacement parts. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 416 Customer Information Read the lease carefully, as you may be charged at the end of the lease for poor quality repairs. If a Crash Occurs If there has been an injury, call emergency services for help. Do not leave the scene of a crash until all matters have been taken care of. Move the vehicle only if its position puts you in danger, or you are instructed to move it by a police officer. Give only the necessary information to police and other parties involved in the crash. For emergency towing see Roadside Assistance Program 0 412. Gather the following information: . Driver name, address, and telephone number . Driver license number . Owner name, address, and telephone number . Vehicle license plate number . Vehicle make, model, and model year . Vehicle Identification Number (VIN) . Insurance company and policy number . General description of the damage to the other vehicle Choose a reputable repair facility that uses quality replacement parts. See “Collision Parts” earlier in this section. If the airbag has inflated, see What Will You See after an Airbag Inflates? 0 66. Managing the Vehicle Damage Repair Process In the event that the vehicle requires damage repairs, GM recommends that you take an active role in its repair. If you have a pre-determined repair facility of choice, take the vehicle there, or have it towed there. Specify to the facility that any required replacement collision parts be original equipment parts, either new Genuine GM parts or recycled original GM parts. Remember, recycled parts will not be covered by the GM vehicle warranty. Insurance pays the bill for the repair, but you must live with the repair. Depending on your policy limits, your insurance company may initially value the repair using aftermarket parts. Discuss this with the repair professional, and insist on Genuine GM parts. Remember, if the vehicle is leased, you may be obligated to have the vehicle repaired with Genuine GM parts, even if your insurance coverage does not pay the full cost.

GM collects information about the use of your vehicle including operational and safety related information. We collect this information to provide, evaluate, improve, and troubleshoot our products and services and to develop new products and services. The protection of vehicle electronics systems and customer data from unauthorized outside electronic access or control is important to GM. GM maintains appropriate security standards, practices, guidelines and controls aimed at defending the vehicle and the vehicle service ecosystem against unauthorized electronic access, detecting possible malicious activity in related networks, and responding to suspected cybersecurity incidents in a timely, coordinated and effective manner. Security incidents could impact your safety or compromise your private data.

In In other Central America and Caribbean Countries, call 52-555-901-2369. Vehicle Data Recording and Privacy The vehicle has a number of computers that record information about the vehicle’s performance and how it is driven or used. For example, the vehicle uses computer modules to monitor and control engine and transmission performance, to monitor the conditions for airbag deployment and deploy them in a crash, and, if equipped, to provide antilock braking to help the driver control the vehicle. These modules may store data to help the dealer technician service the vehicle or to help GM improve safety or features. Some modules may also store data about how the vehicle is operated, such as rate of fuel consumption Cybersecurity Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U. S./Canada/Mexico-15546003) - 2022 - CRC - 5/5/21 Customer Information the event you suspect any security incident impacting your data or the safe operation of your vehicle, please stop operating your vehicle and contact your dealer. Event Data Recorders This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR is to record, in certain crash or near crash-like situations, such as an air bag deployment or hitting a road obstacle, data that will assist in understanding how a vehicle’s systems performed. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less. The EDR in this vehicle is designed to record such data as: . How various systems in your vehicle were operating; . Whether or not the driver and passenger safety belts were buckled/fastened; . How far (if at all) the driver was depressing the accelerator and/or brake pedal; and, . How fast the vehicle was traveling. These data can help provide a better understanding of the circumstances in which crashes and injuries occur. Note EDR data are recorded by your vehicle only if a non-trivial crash situation occurs; no data are recorded by the EDR under normal driving conditions and no personal data (e.g., name, gender, age, and crash location) are recorded. However, other parties, such as law enforcement, could combine the EDR data with the type of personally identifying data routinely acquired during a crash investigation. To read data recorded by an EDR, special equipment is required, and access to the vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties, such as law enforcement, that have the special equipment, can read the information if they have access to the vehicle or the EDR. GM will not access these data or share it with others except: with the consent of the vehicle owner or, if the vehicle is leased, with the consent of the lessee; in response to an official request by police or similar government office; as part of GM's defense of litigation through the discovery process; or, as permitted by law. Data that GM collects or receives may also be used for GM research needs or may be made available to 419 others for research purposes, where a need is shown and the data is not tied to a specific vehicle or vehicle owner. OnStar If the vehicle is equipped with OnStar and has an active service plan, additional data may be collected and transmitted through the OnStar system. This includes information about the vehicle’s operation; collisions involving the vehicle; the use of the vehicle and its features, including infotainment; and the location and approximate GPS speed of the vehicle. Refer to the OnStar Terms and Conditions and Privacy Statement on the OnStar website. See OnStar Additional Information 0 421. Infotainment System If the vehicle is equipped with a navigation system as part of the infotainment system, use of the system may result in the storage of destinations, addresses, telephone numbers, and other trip information. See the infotainment section for information on stored data and for deletion instructions. Chevrolet Silverado 2500 HD/3500 HD Owner Manual (GMNA-Localizing-U.

If GPS signals are not available, the OnStar system should still operate to call OnStar. However, OnStar could have difficulty identifying the exact location. . In emergency situations, OnStar can use the last stored GPS location to send to emergency responders. A temporary loss of GPS can cause loss of the ability to send a Turn-by-Turn Navigation route. The Advisor may give a verbal route or may ask for a call back after the vehicle is driven into an open area. Cellular and GPS Antennas Cellular reception is required for OnStar to send remote signals to the vehicle.
