How to Detect a Tamper Condition If K is pressed on the RKE transmitter and the horn chirps and the lights flash three times, a previous alarm occurred while the system was armed. If the alarm has been activated, a message will appear on the Driver Information Center (DIC). Power Sounder, Inclination Sensor, and Intrusion Sensor In addition to the standard theft-deterrent system features, this system may also have a power sounder, inclination sensor, and intrusion sensor. The power sounder provides an audible alarm, which is distinct from the vehicle’s horn. It has its own power source, and can sound an alarm if the vehicle’s battery is compromised. The inclination sensor can set off the alarm if it senses movement of the vehicle, such as a change in vehicle orientation. The intrusion sensor monitors the vehicle interior, and can activate the alarm if it senses unauthorized entry into the vehicle’s interior. Do not allow passengers or pets to remain in the vehicle when the intrusion sensor is activated. 49 Before arming the theft-deterrent system and activating the intrusion sensor: . Make sure all doors and windows are completely closed. . Secure any loose items such as sunshades. . Make sure there are no obstructions blocking the sensors in the front overhead console.

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 areas are more likely to be seriously injured or killed. Do (Continued) 75 Warning (Continued) 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 0 137. Why Seat Belts Work Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 76 SEATS AND RESTRAINTS 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. 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. 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 95 or Infants and Young Children 0 97. Review and follow the rules for children in addition to the following rules. . Sit up straight and always keep your feet on the floor in front of you (if possible). . Always use the correct buckle for your seating position. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 SEATS AND RESTRAINTS . 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. { Warning You can be seriously injured, or even killed, by not wearing your seat belt properly. Never allow the lap or shoulder belt to become loose or twisted. Never wear the shoulder belt under both arms or behind your back. 77 Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 78 SEATS AND RESTRAINTS 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. Always use the correct buckle for your seating position. If the shoulder portion of a passenger belt is pulled out all the way, the child restraint locking feature may be engaged. If this happens, let the belt go back all the way and start again. Engaging the child restraint locking feature in the front outboard seating position may affect the passenger sensing system. See Passenger Sensing System 0 89. 2. Pick up the latch plate and pull the belt across you. Do not let it get twisted. Never route the lap or shoulder belt over an armrest. 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 SEATS AND RESTRAINTS 79 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 81. Position the release button on the buckle so that the seat belt could be quickly unbuckled if necessary. If the webbing locks in the latch plate before it reaches the buckle, tilt the latch plate flat to unlock. 4. 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. 5.

The belt should return to its stowed position. effectiveness of the seat belt in a crash. See How to Wear Seat Belts Properly 0 76. 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. 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 has a shoulder belt height adjuster for the driver and front outboard passenger seating 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 Press the release button and move the height adjuster to the desired position. The adjuster can be moved up by pushing the slide/trim up. 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. Automatic Seat Belt Tightening System The vehicle may have the Automatic Seat Belt Tightening System. The system activates during emergency braking and/or sudden driving maneuvers and releases when driving conditions return to normal. The system will not activate if the Traction Control/Electronic Stability Control system is not functioning properly. See Traction Control/ Electronic Stability Control 0 219. If there is a problem with the Automatic Seat Belt Tightening System, a message displays on the Driver Information Center (DIC). If a system unavailable message displays repeatedly or a service message displays, see your dealer. Other seat belt functions are not affected by the Automatic Seat Belt Tightening System. Seat Belt Pretensioners This vehicle has seat belt pretensioners for 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 Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 SEATS AND RESTRAINTS crash if the threshold conditions for pretensioner activation are met. Seat belt pretensioners can also help tighten the seat belts in a side crash or a 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 82. 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 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 guide. Seat Belt Use During Pregnancy 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. 81 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. 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. Seat Belt Extender If the vehicle's seat belt will fasten around you, you should use it. But if a seat belt is not long enough, your dealer will order you an extender. 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.

Safety System Check 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. 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 0 137. Keep seat belts clean and dry. See Seat Belt Care 0 82. 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 (Continued) Warning (Continued) 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 SEATS AND RESTRAINTS 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. Airbag System .

See Airbag Readiness Light 0 137. The vehicle has the following airbags: . A frontal airbag for the driver All vehicle airbags have the word AIRBAG on the trim or on a label near the deployment opening. 83 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 knee airbags, the word AIRBAG is on the lower part of the instrument panel. For seat-mounted side impact airbags, the word AIRBAG is on the side of the seatback 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 84 SEATS AND RESTRAINTS Here are the most important things to know about the airbag system: { Warning 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 86. 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 { 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 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. 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 95 or Infants and Young Children 0 97. 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. 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 0 137. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 SEATS AND RESTRAINTS 85 Where Are the Airbags? The driver frontal airbag is in the center of the steering wheel. The front outboard passenger frontal airbag is in the passenger side instrument panel. The driver knee airbag is below the steering column. The front outboard passenger knee airbag is below the glove box. Driver Side Shown, Passenger Side Similar The roof-rail airbags for the driver, front outboard passenger, and second row outboard passengers are in the ceiling above the side windows. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 86 SEATS AND RESTRAINTS Warning (Continued) airbag must be kept clear.

Driver Side Shown, Passenger Side Similar The seat-mounted side impact airbags for the driver and front outboard passenger are in the side of the seatbacks closest to the door. { 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 (Continued) Do not use seat accessories that block the inflation path of a seat-mounted side impact airbag. 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 83. 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. 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, in rear impacts, or in many side impacts. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 SEATS AND RESTRAINTS In addition, the vehicle has advanced technology frontal airbags. Advanced technology frontal airbags adjust the restraint according to either crash severity or occupant interaction. Both roof-rail airbags will inflate when either side of the vehicle is struck, if the sensing system predicts that the vehicle is about to roll over on its side, or in a severe frontal impact. Knee airbags are designed to inflate in moderate to severe frontal or near frontal impacts. Knee airbags are not designed to inflate during vehicle rollovers, in rear impacts, or in many side impacts. In any particular crash, no one can say whether an airbag should have inflated simply because of the vehicle damage or repair costs. 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, 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. 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 85. 87 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 86. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 88 SEATS AND RESTRAINTS Airbags should never be regarded as anything more than a supplement to seat belts. What Will You See after an Airbag Inflates? After frontal, knee, 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 85. 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 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 SEATS AND RESTRAINTS 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. . The vehicle has a crash sensing and diagnostic module which records information after a crash. See Vehicle Data Recording and Privacy 0 408 and Event Data Recorders 0 409. . 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 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 89 word ON or OFF, or the symbol for on or off, will be visible. See Passenger Airbag Status Indicator 0 138. The passenger sensing system turns off the front outboard passenger frontal airbag and knee 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 and knee 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. Whenever possible, children aged 12 and under should be secured in a rear seating position. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 90 SEATS AND RESTRAINTS 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 front outboard passenger airbag(s), no system is fail-safe. No one can guarantee that an airbag will not deploy under some unusual circumstance, even though the airbag(s) are 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. The passenger sensing system is designed to turn off the front outboard passenger frontal airbag and knee airbag if: . The front outboard passenger seat is unoccupied. . The system determines that 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. . 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 and knee airbag, the OFF indicator will light and stay lit as a reminder that the airbags are off. See Passenger Airbag Status Indicator 0 138. The passenger sensing system is designed to turn on the front outboard passenger frontal airbag and knee 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(s) to be enabled, the ON indicator will light and stay lit as a reminder that the airbag(s) are 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 and knee airbag, depending upon the person’s seating posture and body build. Everyone in the vehicle who has Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 SEATS AND RESTRAINTS 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 0 137 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 and knee 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. 91 3. Remove any additional items from the seat such as blankets, cushions, seat covers, seat heaters, or seat massagers. cushion, if adjustable, to make sure that the vehicle seatback is not pushing the child restraint into the seat cushion. 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 Rear Seat) 0 108 or Securing Child Restraints (With the Seat Belt in the Front Seat) 0 110. 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 62. 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 6. Restart the vehicle. The passenger sensing system may or may not turn off the airbags for a child in a child restraint depending upon the child’s size. It is better to secure the child restraint in a rear seat. Never put a rear-facing child restraint in the front seat, even if the ON indicator is not lit. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 92 SEATS AND RESTRAINTS If the Off Indicator Is Lit for an Adult-Sized Occupant 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. 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 and knee airbag: 1. Turn the vehicle off. 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 SEATS AND RESTRAINTS 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 approved by GM for your specific vehicle. See Adding Equipment to the Airbag-Equipped Vehicle 0 93 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. 93 Servicing the Airbag-Equipped Vehicle Adding Equipment to 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 0 406. 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. { Warning For up to 10 seconds after the vehicle is turned off and the 12‐volt 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. 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 . 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 Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 94 SEATS AND RESTRAINTS 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 system from properly turning off the passenger airbag(s). See Passenger Sensing System 0 89. If the vehicle has rollover roof-rail airbags, see Different Size Tires and Wheels 0 353 for additional important information. 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.

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 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 (Continued) 97 Warning (Continued) Warning (Continued) tightened around a child’s neck, the only way to loosen the belt is to cut it. 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 restraint. Never leave children unattended in a vehicle and never allow children to play with the seat belts. 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 is not possible to hold it during a crash.

Never put a rear-facing child restraint in the front 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. Child restraints are devices used to restrain, seat, or position children in the vehicle and are sometimes called child seats or car seats. There are three basic types of child restraints: . Forward-facing child restraints . 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 type of child restraint, there are many different models available. When purchasing a child restraint, be sure it is designed to be used in a motor vehicle. If it is, the restraint will have a label saying that it meets federal motor vehicle safety standards. The restraint manufacturer's instructions that come with the restraint state the weight and height limitations for a particular child restraint. In addition, there are many kinds of restraints available for children with special needs. { Warning 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 SEATS AND RESTRAINTS { Warning A young child's hip bones are still so small that the vehicle's regular 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 appropriate child restraints. 99 Child Restraint Systems 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 100 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 95. 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’s 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) 0 102 for more information. Children can be endangered in a crash if the child restraint is not properly secured in the vehicle. When securing an add-on child restraint, refer to the instructions that come with the restraint which may be on the restraint itself or in a booklet, or both, and to this 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 of the United States and Canada, 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 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. 101 { Warning Warning (Continued) 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. seat as far back as it will go. It is better to secure the child restraint in a rear seat. 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 (Continued) See Passenger Sensing System 0 89 for additional information. 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. 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 102 SEATS AND RESTRAINTS 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. Lower Anchors and Tethers for Children (LATCH System) 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. The LATCH system is designed to make installation of a child restraint easier. 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 seat. Booster seats use the vehicle’s seat belts to secure the child in 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. Make sure to follow the instructions that came with the child restraint, and also the instructions in this manual. 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 and anchor. The LATCH anchorage system can be used until the combined weight of the child plus the child restraint is 29.5 kg (65 lbs). Use the seat belt alone instead of the LATCH anchorage system once the combined weight is more than 29.5 kg (65 lbs). See Securing Child Restraints (With the Seat Belt in the Rear Seat) 0 108 or Securing Child Restraints (With the Seat Belt in the Front Seat) 0 110. Child restraints built after March 2014 will be labeled with the specific child weight up to which the LATCH system can be used to install the restraint. The following explains how to attach a child restraint with these attachments in the vehicle. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 SEATS AND RESTRAINTS Not all vehicle seating positions or child restraints have lower anchors and attachments or top tether anchors and attachments. In this case, the seat belt must be used (with top tether where available) to secure the child restraint.

Top Tether Anchor Lower Anchors A top tether (3, 4) is used to secure the top of the child restraint to the vehicle. A top tether anchor is built into the vehicle. The top tether attachment hook (2) on the child restraint connects to the top tether Lower anchors (1) are metal bars built into the vehicle. There are two lower anchors for each LATCH seating 103 anchor in the vehicle in order to reduce the forward movement and rotation of the child restraint during driving or in a crash. The child restraint may have a single tether (3) or a dual tether (4). Either will have a single attachment hook (2) to secure the top tether to the anchor. Some child restraints with top tethers are designed for use with or without the top tether being attached. Others require the top tether always to be attached. In Canada, the law requires that forward-facing child restraints have a top tether, and that the tether be attached. Be sure to read and follow the instructions for your child restraint. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 104 SEATS AND RESTRAINTS Lower Anchor and Top Tether Anchor Locations Rear Seat I : Seating positions with top tether anchors. H : Seating positions with two lower anchors. To assist in locating the lower anchors, each seating position with lower anchors has two labels, near the crease between the seatback and the seat cushion. The outboard lower anchors are behind the vertical openings in the seat trim. To assist in locating the top tether anchors, the top tether anchor symbol is on the cover. The top tether anchors are behind the rear seat, on the filler panel. Open the covers to access the anchors. Be sure to use an anchor on the same side of the vehicle as the seating position where the child restraint will be placed. Do not secure a child restraint in a position without a top tether anchor if a national or local law requires that the top tether be attached, or if the Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 SEATS AND RESTRAINTS instructions that come with the child restraint say that the top tether must be attached.

Base Level Standard Theme Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 134 INSTRUMENTS AND CONTROLS Here are four things that some owners ask about. None of these show a problem with the fuel gauge: . At the service station, the fuel pump shuts off before the gauge reads full. . It takes a little more or less fuel to fill up than the gauge indicated. For example, the gauge may have indicated the tank was half full, but it actually took a little more or less than half the tank's capacity to fill the tank. . The gauge moves a little while turning a corner or speeding up. . The gauge takes a few seconds to stabilize after the ignition is turned on, and goes back to empty when the ignition is turned off. Engine Oil Pressure Gauge (Base Level Cluster Only) English, Standard Theme Shown Metric, Standard Theme Shown The engine oil pressure gauge shows the engine oil pressure in kPa (kilopascals) when the engine is running. Oil pressure can vary with engine speed, outside temperature and oil viscosity. On some models, the oil pump will vary engine oil pressure according to engine needs. Oil pressure may change quickly as the engine speed or load varies. This is normal. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 INSTRUMENTS AND CONTROLS If the oil pressure warning light or Driver Information Center (DIC) message indicates oil pressure outside the normal operating range, check the vehicle's oil as soon as possible. See Engine Oil 0 297. 135 Engine Coolant Temperature Gauge Caution Lack of proper engine oil maintenance can damage the engine. Driving with the engine oil low can also damage the engine. The repairs would not be covered by the vehicle warranty. Check the oil level as soon as possible. Add oil if required, but if the oil level is within the operating range and the oil pressure is still low, have the vehicle serviced. Always follow the maintenance schedule for changing engine oil.

While driving under normal operating conditions, if the needle moves into the red area, the engine is too hot. Pull off the road, stop the vehicle, and turn off the engine as soon as possible. Standard Theme When the ignition is on, this gauge indicates the battery voltage. When the engine is running, this gauge shows the condition of the charging system. The gauge can transition from a higher to lower or a lower to higher reading. This is normal. If the vehicle is operating outside the normal operating range, the charging system light comes on. See Charging System Light 0 139. Readings outside the normal operating range can also occur when a large number of electrical accessories are operating in the vehicle and the engine is left idling for an extended period. This condition is normal since the charging system is not able to provide full power at engine idle. As engine speeds are increased, this condition should correct itself as higher engine speeds allow the charging system to create maximum power. The vehicle can only be driven for a short time with the readings outside the normal operating range. If the vehicle must be driven, turn off all accessories, such as the radio and air conditioner, and unplug all chargers and accessories. Readings outside the normal operating range indicate a possible problem in the electrical system. Have the vehicle serviced as soon as possible. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 INSTRUMENTS AND CONTROLS Seat Belt Reminders Driver Seat Belt Reminder Light There is a driver seat belt reminder light on the instrument cluster.

See Vehicle Personalization 0 157. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 LIGHTING Battery Load Management The vehicle has Electric Power Management (EPM) that 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. If the vehicle has a voltmeter gauge or a voltage display on the Driver Information Center (DIC), you may see the voltage move 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 of the power needed for very high electrical loads. A high electrical load occurs when several of the following are on, such as: headlamps, high beams, rear window defogger, climate control fan at high speed, heated seats, engine cooling fans, trailer loads, and loads plugged into accessory power outlets. 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. 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. Battery Power Protection The battery saver feature is designed to protect the vehicle's battery. 173 If some interior lamps are left on and the ignition is turned off, the battery rundown protection system automatically turns the lamp off after some time. Exterior Lighting Battery Saver 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 off position and then back to the parking lamp or headlamp position. To keep the lamps on for more than 10 minutes, the ignition must be on or in ACC/ACCESSORY. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 174 INFOTAINMENT SYSTEM Infotainment System Introduction Infotainment . . . . . . . . . . . . . . . . . . . . . 174 Introduction Infotainment See the infotainment manual for information on the radio, audio players, phone, navigation system, and voice or speech recognition.

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 restricts airflow and may cause damage to the air vents. Maintenance Passenger Compartment Air Filter The filter reduces dust, pollen, and other airborne irritants from outside air that is pulled into the vehicle. The filter should be replaced as part of routine scheduled maintenance. See Maintenance Schedule 0 379. See your dealer regarding replacement of the filter. 187 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.

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 75. . Assume that other road users (pedestrians, bicyclists, and other drivers) are going to be careless and make mistakes. Anticipate what they might do and be ready. . Allow enough following distance between you and the driver in front of you. . Focus on the task of driving. { Warning Drinking and then driving is very dangerous. Your reflexes, perceptions, attentiveness, and judgment can be affected by even a small amount of alcohol. You can have a serious — or even fatal — collision if you drive after drinking. Do not drink and drive or ride with a driver who has been drinking. Ride home in a cab; or if you are with a group, designate a driver who will not drink. Control of a Vehicle Braking, steering, and accelerating are important factors in helping to control a vehicle while driving. 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. Steering Drunk Driving Braking Variable Effort Steering Death and injury associated with drinking and driving is a global tragedy. Braking action involves perception time and reaction time. Deciding to push the brake pedal is perception time. Actually doing it is reaction time. The vehicle has a steering system that varies the amount of effort required to steer the vehicle in relation to the speed of the vehicle. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 DRIVING AND OPERATING The amount of steering effort required is less at slower speeds to make the vehicle more maneuverable and easier to park. At faster speeds, the steering effort increases to provide a sport-like feel to the steering. This provides maximum control and stability. Normal use of the power steering assist should return when the system cools down. . Take curves at a reasonable speed. Electric Power Steering . The vehicle has electric power steering. It does not have power steering fluid. Regular maintenance is not required. Reduce speed before entering a curve. . Maintain a reasonable steady speed through the curve. . Wait until the vehicle is out of the curve before accelerating gently into the straightaway. If power steering assist is lost due to a system malfunction, the vehicle can be steered, but may require increased effort. See your dealer if there is a problem. 191 Off-Road Recovery See your dealer if there is a problem. Curve Tips Steering in Emergencies . If the steering wheel is turned until it reaches the end of its travel and is held against that position for an extended period of time, power steering assist may be reduced. There are some situations when steering around a problem may be more effective than braking. . If the steering assist is used for an extended period of time while the vehicle is not moving, power assist may be reduced. 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 192 DRIVING AND OPERATING Loss of Control . 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. 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. Track Events and Competitive Driving Caution This vehicle is neither designed nor intended for track events or other competitive driving. This type of driving may damage the vehicle, and the repairs would not be covered by the vehicle warranty. 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 types of driving conditions and avoid driving through large puddles and deep-standing or flowing water. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 DRIVING AND OPERATING { 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 road is wet enough 193 and you are going fast enough. When the vehicle is hydroplaning, it has little or no contact with the road. . Check all fluid levels and brakes, tires, cooling system, and transmission. There is no hard and fast rule about hydroplaning. The best advice is to slow down when the road is wet. . Shift to a lower gear when going down steep or long hills. 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 0 335. . 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. { 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 194 . DRIVING AND OPERATING 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 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 0 219. . 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) 0 215. Driving on Snow or Ice 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. See Driver Mode Control 0 221. . . 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 Service. See Roadside Service 0 401. 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. If the vehicle is stuck in snow: . Clear snow from the base of the vehicle, especially any blocking the exhaust pipe. (Continued) Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 DRIVING AND OPERATING Warning (Continued) . This keeps the battery charged to restart the vehicle and to signal for help with the headlamps. Do this as little as possible, to save fuel. Open a window about 5 cm (2 in) on the vehicle side that is away from the wind, to bring in fresh air. If the Vehicle Is Stuck . Fully open the air outlets on or under the instrument panel. Slowly and cautiously spin the wheels to free the vehicle when stuck in sand, mud, ice, or snow. . 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.” If stuck too severely for the traction system to free the vehicle, turn the traction system off and use the rocking method. See Traction Control/ Electronic Stability Control 0 219. For more information about CO, see Engine Exhaust 0 208. 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. { 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). 195 Rocking the Vehicle to Get it Out Turn the steering wheel left and right to clear the area around the front wheels. Turn off any traction system. Shift back and forth between R (Reverse) and a low forward gear, spinning the wheels as little as possible. To prevent transmission wear, wait until the wheels stop spinning before shifting gears. Release the accelerator pedal while shifting, and press lightly on the accelerator pedal when the transmission is in gear. 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. If the vehicle does need to be towed out, see Towing the Vehicle 0 367. 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 Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 196 DRIVING AND OPERATING all nonfactory-installed options. Two labels on the vehicle may show how much weight it may properly carry: the Tire and Loading Information label and the Certification label. Tire and Loading Information 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. Overloading can also reduce stopping distance, damage the tires, and shorten the life of the vehicle. Label Example A vehicle-specific Tire and Loading Information label is attached to the vehicle's 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 tire size of the original equipment tires (3) and the recommended cold tire inflation pressures (4). For more information on tires and inflation see Tires 0 335 and Tire Pressure 0 343. There is also important loading information on the Certification label. It may show the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for the front and rear axle. See “Certification 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 DRIVING AND OPERATING 2. Determine the combined weight of the driver and passengers that will be riding in your vehicle. 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.) 197 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. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle.” See Trailer Towing 0 282 for important information on towing a trailer, towing safety rules, and trailering tips. Example 1 1. Vehicle Capacity Weight for Example 1 = 453 kg (1,000 lbs). 2. Subtract Occupant Weight @ 68 kg (150 lbs) × 2 = 136 kg (300 lbs). 3. Available Occupant and Cargo Weight = 317 kg (700 lbs). Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 198 DRIVING AND OPERATING weight of the driver, passengers, and cargo should never exceed the vehicle's capacity weight.

Do not participate in track events, sport driving schools, or similar activities during this break-in period. Follow these recommended guidelines during the first 2 400 km (1,500 mi) of driving this vehicle. Parts have a break-in period and performance will be better in the long run. . Check engine oil with every refueling and add if necessary. Oil and fuel consumption may be higher than normal during the first 2 400 km (1,500 mi). For the first 2 400 km (1,500 mi): . Avoid full throttle starts and abrupt stops. . Do not exceed 4000 engine rpm. . To break in new tires, drive at moderate speeds and avoid hard cornering for the first 300 km (200 mi). New tires do not have maximum traction and may tend to slip. . New brake linings also need a break–in period. Avoid making hard stops during the first 300 km (200 mi). This is recommended every time brake linings are replaced. { Warning Starting and Operating Things inside the vehicle can strike and injure people in a sudden stop or turn, or in a crash. New Vehicle Break-In . . . Put things in the cargo area of the vehicle. In the cargo area, put them as far forward as possible. Try to spread the weight evenly.

This can be used for sport driving or when climbing or descending hills, to stay in gear longer, or to downshift for more power or engine braking. The transmission will only allow shifting into gears appropriate for the vehicle speed and engine revolutions per minute (rpm). If shifting is prevented for any reason, a SHIFT DENIED message will be displayed in the instrument cluster. The transmission will not automatically shift to the next higher gear if the engine rpm is too high. It will only automatically shift to the next lower gear if the engine rpm is much too low. Drive Systems Brakes All-Wheel Drive Antilock Brake System (ABS) Vehicles with this feature always send engine power to all four wheels. It is fully automatic, and adjusts itself as needed for road conditions. 215 This vehicle has an Antilock Brake System (ABS), an advanced electronic braking system that helps prevent a braking skid. When the vehicle begins to drive away, ABS checks itself. A momentary motor or clicking noise may be heard while this test is going on, and it may even be noticed that the brake pedal moves a little. This is normal. If there is a problem with ABS, this warning light stays on. See Antilock Brake System (ABS) Warning Light 0 143. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 216 DRIVING AND OPERATING If driving safely on a wet road and it becomes necessary to slam on the brakes and continue braking to avoid a sudden obstacle, a computer senses the wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work the brakes at each wheel. ABS can change the brake pressure to each wheel, as required, faster than any driver could. This can help you steer around the obstacle while braking hard. As the brakes are applied, the computer keeps receiving updates on wheel speed and controls braking pressure accordingly. Remember: ABS does not change the time needed to get a foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, there will not be enough time to apply the brakes if that vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even with ABS. Using ABS Electric Parking Brake Do not pump the brakes. Just hold the brake pedal down firmly and let ABS work. You may hear the ABS pump or motor operating and feel the brake pedal pulsate. This is normal. When ABS is active, it may be an indication that road surfaces are slippery. Braking sooner may be required for driving conditions. If equipped with electric brake boost, the TCS/StabiliTrak/ESC light will flash when ABS is active. Braking in Emergencies ABS allows you to steer and brake at the same time. In many emergencies, steering can help more than even the very best braking. The vehicle has an Electric Parking Brake (EPB). The EPB can always be activated, even if the ignition is off. To prevent draining the battery, avoid repeated cycles of the EPB system when the engine is not running. The system has a Y or PARK Electric Parking Brake light, and a 8 Service Parking Brake light. See Electric Parking Brake Light 0 142 and Service Electric Parking Brake Light 0 143. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 DRIVING AND OPERATING Before leaving the vehicle, check for the Y or PARK 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. The Y or PARK light will flash and then stay on once the EPB is fully applied. If the Y or PARK 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 Y or PARK light is flashing. See your dealer. See Electric Parking Brake Light 0 142. If the 8 light is on, press the EPB switch and hold it. Continue to hold the switch until the Y or PARK light remains on. If the 8 light remains on, see your dealer. 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. 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 PARK light is off. 217 Y or If the 8 light is on, release the EPB by pressing and holding the EPB switch. Continue to hold the switch until the Y or PARK 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. 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 218 DRIVING AND OPERATING Brake Assist This vehicle has a brake assist feature designed to assist the driver in stopping or decreasing vehicle speed in emergency driving conditions. This feature uses the stability system hydraulic brake control module to supplement the power brake system under conditions where the driver has quickly and forcefully applied the brake pedal in an attempt to quickly stop or slow down the vehicle. The stability system hydraulic brake control module increases brake pressure at each corner of the vehicle until the ABS activates. Minor brake pedal pulsation or pedal movement during this time is normal and the driver should continue to apply the brake pedal as the driving situation dictates. The brake assist feature will automatically disengage when the brake pedal is released or brake pedal pressure is quickly decreased. 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 0 190. Hill Start Assist (HSA) may automatically activate when the vehicle is stopped on a hill and Automatic Vehicle Hold (AVH) is not enabled. This feature is designed to prevent the vehicle from rolling, either forward or rearward, during vehicle drive off. During the transition from releasing the brake pedal to accelerating to drive off on a hill, HSA holds the braking pressure to prevent rolling. HSA will not activate if the vehicle is in a drive gear and facing downhill or if the vehicle is facing uphill and in R (Reverse). Automatic Vehicle Hold (AVH) Automatic Vehicle Hold (AVH), if equipped, can be turned on by pressing AUTO HOLD with the driver seat belt fastened, the driver door closed, and the engine running. The AVH indicator will come on. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 DRIVING AND OPERATING This feature will activate when the vehicle is stopped to prevent it from moving. After the brake pedal has been released and before the accelerator pedal has been pressed, AVH uses braking pressure to hold the vehicle stationary. In addition, the ABS pump motor may activate to build brake pressure to maintain the vehicle at a standstill if necessary. If AVH is holding the vehicle, the AVH indicator will change to green. Once AVH is active it will hold the vehicle for a defined time period then engage the parking brake. While AVH is holding the vehicle, the parking brake will engage if the driver door is opened or the driver seat belt is unfastened. See Automatic Vehicle Hold (AVH) Light 0 144. Ride Control Systems Traction Control/Electronic Stability Control System Operation The vehicle has a Traction Control System (TCS) and StabiliTrak/ Electronic Stability Control (ESC). These systems help limit wheel spin and assist the driver in maintaining control, especially on slippery road conditions. TCS activates if it senses that 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. 219 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. 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 0 195 and “Turning the Systems Off and On” later in this section. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 220 DRIVING AND OPERATING 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. If d comes on and stays on, the vehicle may need more time to diagnose the problem. If the condition persists, see your dealer. To turn off only TCS, press and release Y. The Traction Off light i displays in the instrument cluster and the appropriate DIC message displays. Turning the Systems Off and On To turn TCS on again, press and release Y. The Traction Off light i displayed in the instrument cluster will turn off. To turn off both TCS and StabiliTrak/ ESC, press and hold Y until the Traction Off light i and StabiliTrak/ ESC OFF light g come on and stay on in the instrument cluster. The appropriate DIC message displays. 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. If d comes on and stays on: 1. Stop the vehicle. 2. Turn the engine off and wait 15 seconds. 3. Start the engine. 4. Drive the vehicle. Caution Do not repeatedly brake or accelerate heavily when TCS is off. The vehicle driveline could be damaged. To turn TCS and StabiliTrak/ESC on again, press and release Y. The Traction Off light i and StabiliTrak/ ESC OFF light g in the instrument cluster turn off. Adding accessories can affect vehicle performance.

When a mode is selected, a unique and persistent indicator will display in the Diver Information Center (DIC). Sport Mode Use where road conditions or personal preference demand a more controlled response. When selected, the Sport Mode indicator light will display in the instrument cluster. In this mode, the vehicle monitors driving behaviors and automatically enables Performance Shift Features when spirited driving is detected. These features maintain lower transmission gears to increase available engine braking and improve acceleration response. The vehicle will Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 222 DRIVING AND OPERATING exit these features and return to normal operation after a short period when no spirited driving is detected. The steering including Active Rear Steer (if equipped), will change to provide more precise control. If the vehicle has Magnetic Ride Control, the suspension will change to provide better cornering performance. If the vehicle is equipped with AWD, Sport Mode sends more torque to the rear wheels. For further details on Sport Mode, see “Driver Mode Selector Attributes Affected”. Snow/Ice Mode Snow/Ice Mode is used for slippery surfaces to help control wheel speed. This can compromise the acceleration on dry asphalt. Use when maximum vehicle handling is desired. Snow/Ice Mode will use a different accelerator pedal map to optimize traction on a slippery surface. The accelerator pedal will reduce engine torque at small pedal inputs. When selected, the Snow/Ice Mode indicator light will display in the instrument cluster. 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 0 195. If the vehicle is equipped with AWD, Snow/Ice Mode will provide more torque to the front wheels. For further details on Snow/Ice Mode, see “Driver Mode Selector Attributes Affected”. Track Mode (V-Series Only) Use when maximum vehicle handling is desired. When selected, the Track Mode indicator will display in the instrument cluster. When in Track Mode, the automatic transmission and the accelerator pedal is adjusted to give maximum control during the highest level of spirited driving. The Magnetic Ride Control and steering will be set to the optimum level for vehicle responsiveness. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 DRIVING AND OPERATING 223 Driver Mode Selector Attributes Affected The different modes features are shown below.

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 excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads. 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). 225 If the Traction Control/StabiliTrak/ Electronic Stability Control (ESC) system begins to limit wheel spin while using cruise control, the cruise control automatically disengages. See Traction Control/Electronic Stability Control 0 219. If a collision alert occurs when cruise control is activated, cruise control is disengaged. See Forward Collision Alert (FCA) System 0 260. When road conditions allow cruise control to be safely used, it can be turned back on. Cruise control will disengage if either TCS or StabiliTrak/ESC is turned off. If the brakes are applied, cruise control disengages. J : Press to turn the system on and off. A white indicator appears in the instrument cluster when cruise is turned on.

Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase the vehicle speed. When you take your foot off the pedal, the vehicle will slow down to the previous set cruise speed. How well the cruise control will work on hills depends upon the vehicle speed, load, and the steepness of the hills. When going up steep hills, you might have to step on the accelerator pedal to maintain your speed. When going downhill, the cruise control system may automatically brake to slow the vehicle down. Also, you may have to brake or shift to a lower gear to keep your speed down. If the brake pedal is applied, cruise control disengages. Ending Cruise Control There are four ways to end cruise control: . Step lightly on the brake pedal. . Press *. . Shift the transmission to N (Neutral). . Press 227 J. Erasing Speed Memory The cruise control set speed is erased from memory if J is pressed or if the ignition is turned off. Adaptive Cruise Control If equipped with Adaptive Cruise Control (ACC), it allows for selecting the cruise control set speed and following gap. Read this entire section before using this system. ACC uses a camera and radar sensors to detect other vehicles. See Radio Frequency Statement 0 407. The following gap is the following time (or distance) between your vehicle and a vehicle detected directly ahead in your path, moving in the same direction. If no vehicle is detected in your path, ACC works like regular cruise control. If a vehicle is detected in your path, ACC can speed up the vehicle or apply limited, moderate braking to maintain the selected following gap. To disengage ACC, apply the brake. If the Traction Control System (TCS) or Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 228 DRIVING AND OPERATING StabiliTrak/Electronic Stability Control (ESC) system activates while ACC is engaged, ACC may automatically disengage. See Traction Control/ Electronic Stability Control 0 219. When road conditions allow ACC to be safely used, ACC can be turned back on. ACC will not engage if the TCS or StabiliTrak/ESC is disabled. { Warning ACC has limited braking ability and may not have time to slow the vehicle down enough to avoid a collision with another vehicle you are following. This can occur when vehicles suddenly slow or stop ahead, or enter your lane. Also see “Alerting the Driver” in this section. Complete attention is always required while driving and you should be ready to take action and apply the brakes. See Defensive Driving 0 190. { Warning ACC will not detect or brake for children, pedestrians, animals, or other objects. Do not use ACC when: . On winding and hilly roads or when the sensors are blocked by snow, ice, or dirt. The system may not detect a vehicle ahead. Keep the entire front of the vehicle clean. .

The faster the vehicle speed, the further back your vehicle will follow a vehicle detected ahead. Consider traffic and weather conditions when selecting the following gap. The range of selectable gaps may not be appropriate for all drivers and driving conditions. Changing the gap setting automatically changes the alert timing sensitivity (Far, Medium, or Near) for the Forward Collision Alert (FCA) feature. See Forward Collision Alert (FCA) System 0 260. Alerting the Driver Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 232 DRIVING AND OPERATING If ACC is engaged, driver action may be required when ACC cannot apply sufficient braking because of approaching a vehicle too rapidly. When this condition occurs, the collision alert symbol on the HUD will flash on the windshield. Either eight beeps will sound from the front, or both sides of the Safety Alert Seat will pulse five times. See “Collision/ Detection Systems” under Vehicle Personalization 0 157. See Defensive Driving 0 190. Approaching and Following a Vehicle If this indicator is not displaying, ACC will not respond to or brake for vehicles ahead. ACC automatically slows the vehicle down and adjusts vehicle speed to follow the vehicle in front at the selected follow gap. The vehicle speed increases or decreases to follow the vehicle in front of you, but will not exceed the set speed. It may apply limited braking, if necessary. When braking is active, the brake lamps will come on. The automatic braking may feel or sound different than if the brakes were applied manually. This is normal. Stationary or Very Slow-Moving Objects { Warning The vehicle ahead indicator is on the instrument cluster and HUD display. This indicator only displays when a vehicle is detected in your vehicle’s path moving in the same direction. ACC may not detect and react to stopped or slow-moving vehicles ahead of you. For example, the system may not brake for a vehicle it has never detected moving. This can occur in stop-and-go traffic or (Continued) Warning (Continued) when a vehicle suddenly appears due to a vehicle ahead changing lanes. Your vehicle may not stop and could cause a crash. Use caution when using ACC. Your complete attention is always required while driving and you should be ready to take action and apply the brakes. ACC Automatically Disengages ACC may automatically disengage and you will need to manually apply the brakes to slow the vehicle if: . The sensors are blocked. .

Super Cruise does not steer to prevent a crash with stopped or slow-moving vehicles. You must supervise the driving task and may need to steer and brake to prevent a crash, especially in stop-and-go traffic or when a vehicle suddenly enters your lane. Always pay attention when using Super Cruise. Failure to do so could result in a crash involving serious injury or death. 243 Curves in the Road { Warning The vehicle could drift out of your lane of travel. To prevent crashes, always be ready to manually steer. Super Cruise may not detect your lane on curves in the freeway. Super Cruise may not detect the markings that show your lane. You may not have time to react to a vehicle in the lane next to your vehicle while on curves in the freeway. Super Cruise may operate differently in sharp curves. It may drift out of your lane of travel if the curve is too sharp. When entering a curve, Super Cruise may not detect the lane markings and may not adjust the steering enough to stay in your lane of travel. When this happens, you will need to steer the vehicle. Super Cruise may detect other lane markings that are not in your lane and may or may not steer appropriately to maintain your lane. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 244 DRIVING AND OPERATING Other Vehicles Entering Your Lane Super Cruise may occasionally provide an alert and/or steering that is considered unnecessary. It could respond to lane markings in different lanes, signs, guardrails, and other stationary objects when entering or exiting a curve. This is normal operation. The vehicle does not need service. Super Cruise may not detect a vehicle that enters your lane, or may not brake fast enough to avoid a crash. You must manually brake and steer the vehicle.

This view can also be accessed by touching the Top Down View button when the CAMERA view is active. Park Assist With RPA, and if equipped with FPA, as the vehicle moves at speeds of less than 8 km/h (5 mph) the sensors on the bumpers may detect objects up to 2.5 m (8 ft) behind and 1.2 m (4 ft) in front of the vehicle within a zone 25 cm (10 in) high off the ground and below bumper level. These detection distances may be shorter during warmer or humid weather. Blocked sensors will not detect objects and can also cause false detections. Keep the sensors clean of mud, dirt, snow, ice, and slush; and clean sensors after a car wash in freezing temperatures. { Warning The Park Assist system does not detect children, pedestrians, bicyclists, animals, or objects located below the bumper or that are too close or too far from the vehicle. It is not available at speeds greater than 8 km/h (5 mph). To prevent injury, death, or vehicle damage, even with Park Assist, always check the area around the vehicle and check all mirrors before moving forward or backing. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 DRIVING AND OPERATING Backing Warning and Reverse Automatic Braking The instrument cluster may have a Park Assist display with bars that show “distance to object” and object location information for the Park Assist system. As the object gets closer, more bars light up and the bars change color from yellow to amber to red. When an object is first detected in the rear, one beep will be heard from the rear, or both sides of the Safety Alert Seat will pulse two times. When an object is very close (<0.6 m (2 ft) in the vehicle rear, or <0.3 m (1 ft) in the vehicle front), five beeps will sound from the front or rear depending on object location, or both sides of the Safety Alert Seat will pulse five times. Beeps for FPA are higher pitched than for RPA. Vehicles with Adaptive Cruise Control (ACC) have the Backing Warning System and Reverse Automatic Braking (RAB) system. The Backing Warning part of this system can warn of rear objects when backing up at speeds greater than 8 km/h (5 mph). The Backing Warning System will beep once from the rear when an object is first detected, or pulse twice on both sides of the Safety Alert Seat. When the system detects a potential crash, beeps will be heard from the rear, or five pulses will be felt on both sides of the Safety Alert Seat. There may also be a brief, sharp application of the brakes. { Warning The Backing Warning System only operates at speeds greater than 8 km/h (5 mph). It does not detect children, pedestrians, bicyclists, animals, or objects below the (Continued) 255 Warning (Continued) bumper or that are too close or too far from the vehicle. In some situations, such as at higher backing speeds, there may not be enough time for the short, sharp application of the vehicle brake system to occur. To prevent injury, death, or vehicle damage, even with the Backing Warning System, always check the area around the vehicle and check all mirrors before backing. When the vehicle is in R (Reverse), if the system detects the vehicle is backing too fast to avoid a crash with a detected object behind your vehicle in your path, it may automatically brake hard to a stop to help avoid or reduce the harm caused by a backing crash. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 256 DRIVING AND OPERATING { Warning { Warning RAB may not avoid many types of backing crashes. Do not wait for the automatic braking to apply. This system is not designed to replace driver braking and only works in R (Reverse) when an object is detected directly behind the vehicle. It may not brake or stop in time to avoid a crash. It will not brake for objects when the vehicle is moving at very low speeds. It does not detect children, pedestrians, bicyclists, animals, or objects below the bumper or that are too close or too far from the vehicle. To prevent injury, death, or vehicle damage, even with RAB, always check the area around the vehicle before and while backing. There may be instances where unexpected or undesired automatic braking occurs. If this happens, either press the brake pedal or firmly press the accelerator pedal to release the brakes from the RAB system. Before releasing the brakes, check the RVC and check the area around the vehicle to make sure it is safe to proceed. If the brake pedal is not pressed soon after the stop, the Electric Parking Brake (EPB) may be set. When it is safe, press the accelerator pedal firmly at any time to override RAB. Rear Cross Traffic Alert (RCTA) If equipped, RCTA displays a red warning triangle with a left or right pointing arrow to warn of traffic coming from the left or right. This system detects objects coming from up to 20 m (65 ft) from the left or right side of the vehicle. 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. See Radio Frequency Statement 0 407. Turning the Features On or Off Touch X on the center stack to turn on or off the Front and Rear Park Assist, Reverse Automatic Braking (RAB), Rear Cross Traffic Alert (RCTA), and the Backing Warning System at the same time. The indicator light next to the button comes on when the features are on and turns off when the features have been disabled. Turn off Park Assist, RCTA, and RAB when towing a trailer. To turn the RPA symbols or guidance lines (on some models) on or off, see “Rear Camera Park Assist Symbols” under Vehicle Personalization 0 157. RCTA can also be turned on or off through vehicle personalization. See “Collision/Detection Systems” under Vehicle Personalization 0 157. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 DRIVING AND OPERATING Automatic Parking Assist (APA) with Braking If equipped, APA searches for and steers the vehicle into parallel and perpendicular parking spots. When using APA, you must still shift gears, while the system applies the brakes and accelerator. A display and audible beeps help to guide parking maneuvers. Do not use APA when towing a trailer. { Warning APA may not detect objects in the parking space, objects that are soft or narrow, objects high off the ground such as flatbed trucks, objects below ground level such as large potholes, or moving objects (e.g. pedestrians). Always verify that the parking space is appropriate for parking a vehicle. APA does not respond to changes in the parking space, such as movement of an adjacent vehicle, or a person or object entering the parking space. (Continued) Warning (Continued) APA does not detect or avoid traffic that is behind or alongside of the vehicle. Always be prepared to stop the vehicle during the parking maneuver. Touch O on the center stack to enable the system to search for a parking space that is large enough and within 1.5 m (5 ft) of the vehicle. The vehicle speed must be below 30 km/h (18 mph). The system cannot: . Detect whether it is a legal parking space. . Park exactly lined up with the vehicle next to it if the spot is approached at an angle or if the parking space is angled. . Park exactly centered in a spot that is marked too large. . Always detect short curbs. When enabled, APA searches for parallel parking spaces to the right of the vehicle. To search for a parking 257 space to the left, turn on the left turn signal or, if available, change the side selection in the infotainment display. To switch the parking mode between parallel and perpendicular, touch and hold O during the search process or, if available, change the parking mode in the infotainment display. After completely passing a large enough space, an audible beep occurs. A red stop symbol and a shift to reverse message are displayed. If the vehicle is in R (Reverse), but does not steer into the expected space, this may be because the system is maneuvering the vehicle into a previously detected space. The APA system does not need service. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 258 DRIVING AND OPERATING APA will instruct the vehicle to stop once a large enough space is found. Follow the displayed instructions. Shift to R (Reverse) to engage automatic steering. The steering wheel will vibrate briefly as a reminder to remove hands from the steering wheel. APA uses idle speed and braking to park. If idle speed is not sufficient, gently press the accelerator. Check surroundings and be prepared to stop to avoid vehicles, pedestrians, or objects not detected by the system. In case the driver brakes, APA will not disengage. Manual steering by the driver automatically disengages APA. Vehicle speed is limited to a maximum of 5 km/h (3 mph) during the parking maneuver. A progress arrow displays the status of the parking maneuver. Depending on the space size, additional maneuvers may be required, and there will be additional instructions. When changing gears, allow the automatic steering to complete before continuing the parking maneuver. APA will beep and display a PARKING COMPLETE message. Apply the brakes and place the vehicle in P (Park). The brake holds the vehicle until the parking brake or brake is applied, or the vehicle is shifted into P (Park). APA may automatically disengage if: . The steering wheel is used by the driver. . The maximum allowed speed is exceeded. . The parking brake is applied or the vehicle is shifted into P (Park). . There is a failure with the APA system. . Electronic stability control or antilock brakes are activated. . A high priority vehicle message is displayed in the DIC. . The driver opens the door with an unbuckled seat belt. Rear Pedestrian Alert To cancel APA, touch O again. When the System Does Not Seem to Work Properly The APA system may require a short period of driving along curves to calibrate. Under certain conditions, this feature can provide alerts for a pedestrian within the system’s range directly behind the vehicle. This feature only works in R (Reverse) below 12 km/h (8 mph), and detects pedestrians up to 8 m (26 ft) away during daytime driving. During nighttime driving, feature performance is very limited. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 DRIVING AND OPERATING Warning (Continued) .

When approaching a vehicle ahead too quickly, FCA provides a red flashing alert on the windshield and rapidly beeps or pulses the driver seat. 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). If the vehicle has Adaptive Cruise Control (ACC), it can detect vehicles to distances of approximately 110 m (360 ft) and operates at all speeds. See Adaptive Cruise Control 0 227. { Warning FCA is a warning system and does not apply the brakes. When approaching a slower-moving or stopped vehicle ahead too rapidly, (Continued) Warning (Continued) 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 objects. Be ready to take action and apply the brakes. See Defensive Driving 0 190. FCA can be disabled with either the FCA steering wheel control or, if equipped, through vehicle personalization. See “Collision/ Detection Systems” under Vehicle Personalization 0 157. Detecting the Vehicle Ahead 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. { 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.

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 Selecting the Alert Timing 261 The Collision Alert control is on the steering wheel. Press [ to set the FCA timing to Far, Medium, or Near, or on some vehicles, Off. 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. If your vehicle is equipped with Adaptive Cruise Control (ACC), changing the FCA timing setting automatically changes the following gap setting (Far, Medium, or Near). Following Distance Indicator The following distance to a moving vehicle ahead in your path is indicated in following time in seconds on the Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 262 DRIVING AND OPERATING Driver Information Center (DIC). See Driver Information Center (DIC) 0 149. The minimum following time is 0.5 seconds away. If there is no vehicle detected ahead, or the vehicle ahead is out of sensor range, dashes will be displayed. Unnecessary Alerts 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. 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. Forward Automatic Braking (FAB) { Warning If the vehicle has Forward Collision Alert (FCA), it also has FAB, which 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 forward automatic 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 0 260. FAB is an emergency crash preparation feature and is not designed to avoid crashes. Do not rely on FAB to brake the vehicle. FAB will not brake outside of its operating speed range and only responds to detected vehicles. The system works when driving in a forward gear between 8 km/h (5 mph) and 80 km/h (50 mph), or on vehicles with Adaptive Cruise Control (ACC), above 4 km/h (2 mph). It can detect vehicles up to approximately 60 m (197 ft). FAB 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. 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 DRIVING AND OPERATING FAB may slow the vehicle to a complete stop to try to avoid a potential crash. If this happens, FAB may engage the Electric Parking Brake (EPB) to hold the vehicle at a stop. Release the EPB or firmly press the accelerator pedal. { Warning FAB 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 FAB, 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. 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. FAB and IBA can be disabled through vehicle personalization. See “Collision/ Detection Systems” under Vehicle Personalization 0 157. { Warning Using FAB or IBA while towing a trailer could cause you to lose control of the vehicle and crash. (Continued) 263 Warning (Continued) Turn the system to Alert, or if the vehicle has ACC to 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 FAB system does not need service. Front Pedestrian Braking (FPB) System If equipped, the FPB system may help avoid or reduce the harm caused by front-end crashes with nearby pedestrians when driving in a forward gear. FPB displays an amber indicator, ~, when a nearby Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 264 DRIVING AND OPERATING pedestrian is detected directly ahead. When approaching a detected pedestrian too quickly, FPB provides a red flashing alert on the windshield and rapidly beeps or pulses the driver seat. FPB can provide a boost to braking or automatically brake the vehicle. This system includes Intelligent Brake Assist (IBA), and the Forward Automatic Braking (FAB) System may also respond to pedestrians. See Forward Automatic Braking (FAB) 0 262. The FPB system can detect and alert to pedestrians in a forward gear at speeds between 8 km/h (5 mph) and 80 km/h (50 mph). During daytime driving, the system detects pedestrians up to a distance of approximately 40 m (131 ft). During nighttime driving, system performance is very limited. If the vehicle is equipped with the Night Vision system, during nighttime driving, the vehicle can detect and alert to pedestrians whenever in a forward gear. { Warning FPB does not provide an alert or automatically brake the vehicle, unless it detects a pedestrian. FPB may not detect pedestrians, including children: . When the pedestrian is not directly ahead, fully visible, or standing upright, or when part of a group. . Due to poor visibility, including nighttime conditions, fog, rain, or snow. . If the FPB sensor is blocked by dirt, snow, or ice. . If the headlamps or windshield are not cleaned or in proper condition. FPB can be set to Off, Alert, or Alert & Brake through vehicle personalization. See “Front Pedestrian Detection” in “Collision/Detection Systems” under Vehicle Personalization 0 157. Detecting the Pedestrian Ahead FPB alerts and automatic braking will not occur unless the FPB system detects a pedestrian. When a nearby pedestrian is detected directly in front of the vehicle, the pedestrian ahead indicator will display amber. Front Pedestrian Alert Be ready to take action and apply the brakes. For more information, see Defensive Driving 0 190. Keep the windshield, headlamps, and FPB sensor clean and in good repair. With Head-Up Display Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 DRIVING AND OPERATING Without Head-Up Display When the vehicle approaches a pedestrian ahead too rapidly, the red FPB alert display will flash on the windshield. Eight rapid high-pitched beeps will sound from the front, or both sides of the Safety Alert Seat will pulse five times. When this Pedestrian 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 Front Pedestrian Alert occurs. Automatic Braking If FPB detects it is about to crash into a pedestrian directly ahead, and the brakes have not been applied, FPB may automatically brake moderately or brake hard. This can help to avoid some very low speed pedestrian crashes or reduce pedestrian injury. FPB can automatically brake to detected pedestrians between 8 km/h (5 mph) and 80 km/h (50 mph). Automatic braking levels may be reduced under certain conditions, such as higher speeds. If also equipped with the Night Vision system, pedestrians detected by the Night Vision system will not cause automatic braking to occur. If this happens, Automatic Braking may engage the Electric Parking Brake (EPB) to hold the vehicle at a stop. Release the EPB. A firm press of the accelerator pedal will also release Automatic Braking and the EPB. { Warning FPB may alert or automatically brake the vehicle suddenly in situations where it is unexpected and undesired. It could falsely alert or brake for objects similar in shape or size to pedestrians, including (Continued) 265 Warning (Continued) shadows. This is normal operation and the vehicle does not need service. To override Automatic Braking, firmly press the accelerator pedal, if it is safe to do so. Automatic Braking can be disabled through vehicle personalization. See “Front Pedestrian Detection” in “Collision/Detection Systems” under Vehicle Personalization 0 157. { Warning Using the Front Pedestrian Braking system while towing a trailer could cause you to lose control of the vehicle and crash.

Night Vision System If equipped, this system can help the driver see and alert the driver to pedestrians or large animals ahead of the vehicle beyond the area lit by the headlamps. A thermal heat image of the view ahead is displayed when it is dark enough outside. If a pedestrian or large animal is detected more than 25 m (82 ft) away, an amber pedestrian or animal icon displays and a box appears around the pedestrian or animal. When the system detects that the vehicle is approaching a pedestrian ahead much too quickly, the box changes to red. With the Front Pedestrian Braking system turned on, Night Vision provides a red Head-Up Display (HUD) alert when the system detects that the vehicle is approaching a pedestrian ahead much too quickly. In addition, an alert beeps or the Safety Alert Seat pulses, if equipped. See Front Pedestrian Braking (FPB) System 0 263. { Warning The system does not detect all objects or the vehicle distance from objects. The system may not provide a warning with enough time to help avoid a crash. 1. Low-Beam Headlamps 2. High-Beam Headlamps 3. Night Vision System By selecting a view on the instrument cluster, the Night Vision image can be displayed. See Instrument Cluster (Uplevel) 0 130 or Instrument Cluster (Base Level) 0 127. The Night Vision system can operate only if: . The ignition is on. . The vehicle is in P (Park) or a forward gear. . It is dark enough outside. . The headlamps are on. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 DRIVING AND OPERATING Adjust the instrument panel brightness to make the image no brighter than necessary. Turn the image off by selecting another view on the instrument cluster. Warm objects, such as pedestrians, animals, and other moving vehicles, should appear whiter on the Night Vision display. Cold objects, such as the sky, signs, and parked vehicles, should appear darker. Night Vision only shows objects that are warmer or colder than the surroundings. It does not detect brake lamps, turn signals, emergency flashers, traffic lights, or sign information. Use this system as an aid by occasionally glancing at the image. Do not stare at the image or use the image under well-lit conditions. { Warning Do not stare at the image while driving as this might cause important objects ahead not to be seen. You could crash, and you or others could be injured. When a pedestrian or large animal is detected, an amber box displays around the pedestrian or animal on the Night Vision display and an amber pedestrian icon, ~, or animal icon, !, displays on the instrument cluster. This pedestrian icon is also shown on the Head-Up Display (HUD). When the system detects the vehicle is approaching a pedestrian much too quickly, the amber pedestrian icon and box turns red, and a red flashing icon, ~, displays on the HUD with rapid beeping or pulsing of the Safety Alert Seat, if equipped. System pedestrian icons, beeps, and (if equipped) Safety Alert Seat pulses can be set to Off through vehicle personalization by turning off the Front Pedestrian Braking system. See “Front Pedestrian Detection” in “Collision/Detection Systems” under Vehicle Personalization 0 157. 267 { Warning The Night Vision system does not automatically brake the vehicle.

For more information, see Defensive Driving 0 190. Keep the Night Vision sensor clean and in good repair. Pedestrian detection may not be available in high outside temperatures. An amber icon, *, displays. The system does not need service. In rain, snow, or fog the image may not be clear and the direction of the road ahead may not be seen. In more severe weather conditions, the image may be unclear and unusable. The system does not need service. Keep the system sensor clean by activating the windshield washer up to five times when it is dark enough for the system to operate. If the Night Vision image still looks blurry, use a soft wet cloth to gently clean the sensor camera lens and dry thoroughly. The sensor is behind the front grille to the inside of the driver side headlamp. The camera must also be aligned to work correctly. If the camera needs adjustment, see your dealer. Do not attempt to adjust the camera yourself. 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 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. 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 LCA warning display will light up in the corresponding outside 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 DRIVING AND OPERATING LCA Detection Zones 1. SBZA Detection Zone 2. LCA Detection Zone 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. How the System Works The LCA symbol lights up in the outside 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 Outside Mirror Display Right Outside Mirror Display 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 outside 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 269 signal is activated in the same direction as a detected vehicle, this display will flash as an extra warning not to change lanes. LCA can be disabled. When you disable LCA, Side Blind Zone Alert is also disabled. See “Collision/Detection Systems” under Vehicle Personalization 0 157. If LCA is disabled by the driver, the LCA mirror displays will not light up. 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 side of the vehicle do not move further back when a trailer is towed. Use caution while changing lanes when towing a Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 270 DRIVING AND OPERATING 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 0 369. 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. 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. Take the vehicle to your dealer. Radio Frequency Information See Radio Frequency Statement 0 407. Lane Departure Warning (LDW) If equipped, LDW may help avoid crashes due to unintentional lane departures. It may provide a warning if the vehicle is crossing a detected lane marking without using a turn signal in the lane departure direction. Since this system is part of the Lane Keep Assist (LKA) system, read the entire LKA section before using this feature. Lane Keep Assist (LKA) If equipped, LKA may help avoid crashes due to unintentional lane departures. It may assist by gently turning the steering wheel if the vehicle approaches a detected lane marking without using a turn signal in that direction. It may also provide a Lane Departure Warning (LDW) system alert as the lane marking is crossed. The LKA system will not assist or provide an LDW alert if it detects that you are actively steering. Override LKA by turning the steering wheel. LKA uses a camera to detect lane markings between 60 km/h (37 mph) and 180 km/h (112 mph). { Warning The LKA system does not continuously steer the vehicle. It may not keep the vehicle in the lane or give a Lane Departure Warning (LDW) alert, even if a lane marking is detected.

Even with LKA and LDW, (Continued) { Warning Using LKA while towing a trailer or on slippery roads could cause loss of control of the vehicle and a crash. Turn the system off. When on, the LKA indicator is green if LKA is available to assist and provide LDW alerts. It may assist by gently turning the steering wheel and display amber if the vehicle approaches a detected lane marking without using a turn signal in that direction. It may also provide an LDW alert by flashing amber as the lane marking is crossed. Additionally, there may be three beeps, or the driver seat may pulse three times, on the right or left, depending on the lane departure direction. Take Steering How the System Works The LKA camera sensor is on the windshield ahead of the rearview mirror. To turn LKA on and off, press on the center stack. 271 A The LKA system does not continuously steer the vehicle.

Close vehicles ahead. . Sudden lighting changes, such as when driving through tunnels. . Banked roads. . Roads with poor lane markings, such as two-lane roads. If the LKA system is not functioning properly when lane markings are clearly visible, cleaning the windshield may help. A camera blocked message may display if the camera is blocked. Cleaning the outside of the windshield behind the rearview mirror may correct the issue. Some driver assistance systems may have reduced performance or not work at all. An LKA or LDW unavailable message may display if the systems are temporarily unavailable. This message could be due to a blocked camera. The LKA system does not need service. Clean the outside of the windshield behind the rearview mirror. LKA assistance and/or LDW alerts may occur due to tar marks, shadows, cracks in the road, temporary or construction lane markings, or other road imperfections. This is normal system operation; the vehicle does not need service. Turn LKA off if these conditions continue.

Avoid using electronic devices. 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 0 367. To tow the vehicle behind another vehicle such as a motor home, see Recreational Vehicle Towing 0 368. When towing with the 2.0L L4 engine, only use unleaded gasoline with an octane rating of 89 or higher. Using gasoline with a lower octane rating while towing may damage the engine and may not be covered by the vehicle warranty. See Recommended Fuel (2.0L L4 Turbo Engine) 0 274 or Recommended Fuel (3.0L Twin Turbo V6 and 4.2L Twin Turbo V8 Engines) 0 275 or Recommended Fuel (3.6L V6 Engine) 0 275. 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 DRIVING AND OPERATING Successful, safe trailering takes correct equipment, and it has to be used properly. . It is recommended to perform the first oil change before heavy towing. 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. . 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). If the transmission downshifts too often, a lower gear may be selected using M (Manual Mode). See Manual Mode 0 214. 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. If equipped, the following driver assistance features should be turned off when towing a trailer: . Adaptive Cruise Control (ACC) . Super Cruise Control . Lane Keep Assist (LKA) . Park Assist . Automatic Parking Assist (APA) . Reverse Automatic Braking (RAB) 279 If equipped, the following driver assistance features should be turned to alert or off when towing a trailer: . Forward Automatic Braking System (FAB) . Intelligent Brake Assist (IBA) . 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 280 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 0 208. 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. The trailer structure, the tires, and the brakes must be 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 and attachments, safety chains, electrical connectors, lamps, tires, and mirrors. See Towing Equipment 0 283. If the trailer has electric brakes, start the combination moving and then manually apply the trailer brake controller to check 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. Following Distance 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. Passing 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 beyond the passed vehicle before returning to the lane. Pass on level roadways. Avoid passing on hills if possible. Towing with a Stability Control System Backing Up 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. 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 DRIVING AND OPERATING 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 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. 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. Vehicles 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. 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 0 310. Parking on Hills { Warning To prevent serious injury or death, always park your vehicle and trailer on a level surface when possible. 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. 281 2. Have someone place chocks under the trailer wheels. 3. When the wheel chocks are in place, release the regular brakes until the chocks absorb the load. 4. Reapply the brake pedal. Then apply the parking brake and shift into P (Park). 5. Release the brake pedal. Leaving After Parking on a Hill 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 282 DRIVING AND OPERATING Maintenance when Trailer Towing Caution (Continued) { Warning 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. 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. The vehicle needs service more often when used to tow trailers. See Maintenance Schedule 0 379. It is especially important to check the automatic transmission fluid, engine oil, axle lubricant, belts, cooling system, and brake system before and during each trip. Trailer Weight Check periodically that all nuts and bolts on the trailer hitch are tight. { Warning Engine Cooling when Trailer Towing Never exceed the towing capacity for your vehicle. The cooling system may temporarily overheat during severe operating conditions. See Engine Overheating 0 310. Trailer Towing Caution Towing a trailer improperly can damage the vehicle and result in costly repairs not covered by the (Continued) Safe trailering requires monitoring the weight, speed, altitude, road grades, outside temperature, dimensions of the front of the trailer, and how frequently the vehicle is used to tow a trailer. 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. Gross Vehicle Weight Rating (GVWR) For information about the vehicle's maximum load capacity, see Vehicle Load Limits 0 195. When calculating the GVWR with a trailer attached, the trailer tongue weight must be included as part of the weight the vehicle is carrying. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 DRIVING AND OPERATING Maximum Trailer Weight The trailer should never weigh more than 454 kg (1,000 lb). The maximum allowable weight of the trailer may be lower based on the weight of the passengers and cargo in your trailer. 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. 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 your vehicle, hitch, and trailer. 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. After loading the trailer, separately weigh the trailer and then the trailer tongue to see if the weights 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. Ask your dealer for trailering information or assistance. 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. The trailer tongue weight (1) should be 10–15% of the loaded trailer weight (2). Some specific trailer types, such as boat trailers, fall outside of 283 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 Towing Equipment Hitches Always use the correct hitch equipment for your vehicle. Crosswinds, large trucks going by, and rough roads can affect the trailer and the hitch. Never attach rental hitches or other bumper-type hitches. Only use frame-mounted hitches that do not attach to the bumper. Always seal any holes in your vehicle if the trailer hitch removed. If not sealed, dirt, water, and carbon monoxide (CO) from the exhaust may enter your vehicle. See Engine Exhaust 0 208. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 284 DRIVING AND OPERATING Tires Trailer Brakes Trailer Tires . 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 0 335 for instructions on proper tire inflation. 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 brake system. If you do, both the vehicle anti-lock brakes and the trailer brakes may not function, which could result in a crash. 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. Safety Chains Always attach chains between the vehicle and the trailer, and attach the chains to the holes on the trailer hitch platform. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. 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 just enough slack so the combination can turn. Never allow safety chains to drag on the ground. 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. 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. 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 DRIVING AND OPERATING 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. 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). 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) 0 139. 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. 285 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. The vehicle has an airbag system. Before attempting to add anything electrical to the vehicle, see Servicing the Airbag-Equipped Vehicle 0 93 and Adding Equipment to the Airbag-Equipped Vehicle 0 93. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 286 VEHICLE CARE Vehicle Care General Information General Information . . . . . . . . . . . . .

Checking Engine Oil Engine Oil 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” later in this section. 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 0 290 for the location. { 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 298 VEHICLE CARE 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. When to Add Engine Oil 2.0L L4 Turbo (LSY) and 4.2L V8 Twin Turbo (LTA) Engines 3.0L V6 Twin Turbo (LGW) and 3.6L V6 (LGX) Engines 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 0 393. 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 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 0 290 for the location of the engine oil fill cap. Add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when through. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 VEHICLE CARE Selecting the Right Engine Oil (Except 4.2L V8 Twin Turbo (LTA) Engine) Selecting the right engine oil depends on both the proper oil specification and viscosity grade. See Recommended Fluids and Lubricants 0 388. Specification 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. See www.gmdexos.com. Viscosity Grade Specification Except the 2.0L L4 Turbo (LSY) engine, 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), an SAE 0W-30 oil may be used. An oil of this viscosity grade will provide easier cold starting for the engine at extremely low temperatures. Use engine oils that meet the dexos2 specification. Failure to use the recommended engine oil or equivalent can result in engine damage not covered by the vehicle warranty. Engine oils that have been approved by GM as meeting the dexos2 specification are marked with the dexos2 approved logo. For the 2.0L L4 Turbo (LSY) engine, use SAE 0W-20 viscosity grade engine oil. 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. Selecting the Right Engine Oil (4.2L V8 Twin Turbo (LTA) Engine) Caution 299 Selecting the right engine oil depends on both the proper oil specification and viscosity grade. See Recommended Fluids and Lubricants 0 388. 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 0W-40 viscosity grade engine oil. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 300 VEHICLE CARE 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. Engine Oil Additives/Engine Oil Flushes Do not add anything to the oil. The recommended oils meeting the dexos specification are all that is needed for good performance and engine protection. 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. Engine Oil Life System When to Change Engine 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. When the system has calculated that oil life has been diminished, it indicates that an oil change is necessary. A CHANGE ENGINE OIL SOON message comes on. 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. Your dealer has trained service people who 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 VEHICLE CARE 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. To reset the system: 1. Using the DIC buttons, display REMAINING OIL LIFE on the DIC. See Driver Information Center (DIC) 0 149. 2. Press and hold SEL to clear the CHANGE ENGINE OIL SOON message and reset the oil life at 100%. Be careful not to reset the oil life display accidentally at any time other than after the oil is changed. It cannot be reset accurately until the next oil change. The oil life system can also be reset as follows: 1. Using the DIC buttons, display REMAINING OIL LIFE on the DIC. See Driver Information Center (DIC) 0 149. 2. Fully press and release the accelerator pedal three times within five seconds. If the CHANGE ENGINE OIL SOON message is not on, the system is reset. The system is reset when the CHANGE ENGINE OIL SOON message is off. If the CHANGE ENGINE OIL SOON message comes back on when the vehicle is started, the engine oil life system has not been reset. Repeat the procedure. Automatic Transmission Fluid How to Check Automatic Transmission Fluid It is not necessary to check the transmission fluid level. A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to your dealer and have it repaired as soon as possible. 301 The vehicle is not equipped with a transmission fluid level dipstick. There is a special procedure for checking and changing the transmission fluid. Because this procedure is difficult, this should be done at the dealer. Contact your dealer for additional information. 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 0 388.

If coolant is visible but not at or above the indicated mark, add a 50/50 mixture of clean, drinkable water and DEX-COOL coolant. Be sure the cooling system, including the coolant surge tank pressure cap, is cool before this is done. See Engine Overheating 0 310. 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. { 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. 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. All Engines Except 2.0L L4 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-quarter of a turn. If you hear a hiss, wait for that to stop. This will allow any pressure still left to be vented out the discharge hose. 2. Keep turning the pressure cap slowly and remove it. 3. Fill the coolant surge tank with the proper mixture to the indicated level mark. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 VEHICLE CARE 4. With the coolant surge tank pressure cap off, start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan. 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 level 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. If the coolant still is not at the proper level when the system cools down again, see your dealer. 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. 2.0L L4 Engine Only - Automatic Coolant Service Fill Instructions If equipped, this feature assists in filling and removing air from the cooling system after service of components or when coolant is added after being too low.

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 engine coolant temperature gauge is no longer in the overheated area or the engine coolant temperature warning light no longer displays, the vehicle can be driven. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 VEHICLE CARE Continue to drive the vehicle slowly for about 10 minutes. Keep a safe 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 no sign of steam, idle the engine for three minutes while parked. If the warning is still displayed, turn off the engine until it cools down. Washer Fluid Adding Washer Fluid Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview 0 290 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. . Do not use engine coolant (antifreeze) in the windshield washer. It can damage the windshield washer system and paint. (Continued) What to Use When windshield washer fluid is needed, be sure to read the manufacturer's instructions before use. If operating the vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing. 311 Caution (Continued) . 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 pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound can come and go or can be Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 312 VEHICLE CARE 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. inspect brake pads for wear and evenly tighten wheel nuts in the proper sequence to torque specifications. See Capacities and Specifications 0 393. Brake pads should always 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. Caution Replacing Brake System Parts Continuing to drive with worn-out brake pads could result in costly brake repair. Always replace brake system parts with new, approved replacement parts. If this is not done, the brakes may not work properly. The braking performance expected can change in many other ways if the wrong replacement brake parts are installed or if parts are improperly installed. Some driving conditions or climates can cause a brake squeal when the brakes are first applied or lightly applied. 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, Electric Brake Boost If equipped, this vehicle may have an electrically boosted power braking system. The system works with the Antilock Brake System (ABS) and the Brake Assist system to aid the driver during various braking situations. See Antilock Brake System (ABS) 0 215. Brake Pad Life System When to Change Brake Pads If equipped, this system 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. 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 Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 VEHICLE CARE sensors are installed, a message will display. Follow the prompts to reset the system. are worn can still determine when the pads should be replaced. See Brakes 0 311. The brake pad life system can also be manually reset: To turn off the brake pad life system: 1. Display Brake Pad Life on the DIC. See Driver Information Center (DIC) 0 149. 2. Press and hold SEL. Select front or rear pads as appropriate. 3. Select YES on the confirmation message. Repeat for pads on the other axle if they were also replaced. 1. Display Brake Pad Life on the DIC. See Driver Information Center (DIC) 0 149. 2. Select DISABLE. To turn the brake pad life system back on, follow the above steps but select ENABLE in Step 2. Brake Fluid 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 313 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. The brake master cylinder reservoir is filled with GM approved DOT 3 brake fluid as indicated on the reservoir cap. See Engine Compartment Overview 0 290 for the location of the reservoir. 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 installed. Add or remove fluid, as necessary, only when work is done on the brake hydraulic system. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 314 VEHICLE CARE { 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 (3.0L Twin Turbo and 3.6L V6 Engines) 0 141 or Brake System Warning Light (2.0L L4 Turbo and 4.2L Twin Turbo V8 Engines) 0 141. 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 0 379. What to Add Use only GM approved DOT 3 brake fluid from a clean, sealed container. See Recommended Fluids and Lubricants 0 388. { 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. The battery is in the trunk under the spare tire. Refer to the replacement number shown on the original battery label when a new 12-volt battery is needed. The vehicle has an Absorbed Glass Mat (AGM) 12-volt battery. Installation of a standard 12-volt battery will result in reduced 12-volt battery life. When using a 12-volt battery charger on the 12-volt AGM battery, some chargers have an AGM battery setting on the charger. If available, use the AGM setting on the charger, to limit charge voltage to 14.8 volts. Caution Stop/Start System If brake fluid is spilled on the vehicle's painted surfaces, the paint finish can be damaged. Immediately wash off any painted surface. Vehicles equipped with a 2.0L LSY, 3.0L LGW, 3.6L LGX, or 4.2L LTA engine are equipped with a Stop/Start system to shut off the engine to help conserve fuel. See Stop/Start System 0 202. Battery - North America The original equipment battery is maintenance free. Do not remove the cap and do not add fluid. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 VEHICLE CARE { Warning WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

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. Fuses and circuit breakers protect power devices in the vehicle. Replace a bad fuse with a new one of the identical size and rating. If there is a problem on the road and a fuse needs to be replaced, the same amperage fuse can be borrowed. Choose some feature of the vehicle that is not needed to use and replace it as soon as possible. Headlamp Wiring 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. Wiper function is available immediately after the wiper switch is set to off, and back to on. To protect the wiper motor from overheating, the wipers may slow down when the windshield is dry for a long period of time. If a period of dry operation, or little moisture, exceeds 10 minutes, the wipers may switch to intermittent operation, and remain there. When moisture is again detected on the windshield, wiper operation will return to the operator selected speed. Although the circuit is protected from electrical overload, overload due to heavy snow or ice may cause wiper linkage damage. Always clear ice and heavy snow from the windshield before using the windshield wipers. If the overload is caused by an electrical problem and not snow or ice, be sure to get it fixed. Fuses and Circuit Breakers The wiring circuits in the vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of damage caused by electrical problems. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 VEHICLE CARE { Danger Fuses and circuit breakers are marked with their ampere rating. Do not exceed the specified amperage rating when replacing fuses and circuit breakers. Use of an oversized fuse or circuit breaker can result in a vehicle fire. You and others could be seriously injured or killed. Engine Compartment Fuse Block 2.0L, 3.0L and 3.6L Engines This fuse block is on the driver side of the engine compartment. To check a fuse, look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a new one of the identical size and rating. Fuses of the same amperage can be temporarily borrowed from another fuse location, if a fuse goes out. Replace the fuse as soon as possible. Lift the fuse block cover to access the fuses. 321 The vehicle may not be equipped with all of the fuses and relays shown.

Underinflated tires pose the same danger as overloaded tires. The resulting crash could cause serious injury. Check all tires frequently to 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. (Continued) Warning (Continued) . Replace any tires that have been damaged by impacts with potholes, curbs, etc. . Improperly repaired tires can cause a crash. Only the dealer or an authorized tire service center should repair, replace, dismount, and mount the tires. . 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. See Tire Pressure for High-Speed Operation 0 344 for inflation pressure adjustment for high-speed driving. 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 0 336. Winter Tires This vehicle was not originally equipped with winter tires. Winter tires are designed for increased traction on snow and ice-covered Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 VEHICLE CARE 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 0 352. 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. 337 Low-Profile Tires Summer Tires If the vehicle has 245/45R19, 245/40R20, or 245/40ZR20 size tires, they are classified as low-profile tires. This vehicle may come with 245/40ZR20 high performance summer tires. These tires have a special tread and compound that are optimized for maximum dry and wet road performance. This special tread and compound will have decreased performance in cold climates, and on ice and snow. It is recommended that winter tires be installed on the vehicle if frequent driving at temperatures below approximately 5 °C (40 °F) or on ice or snow covered roads is expected. See Winter Tires 0 336. Caution Low-profile tires are more susceptible to damage from road hazards or curb impact than standard profile tires. Tire and/or wheel assembly damage can occur when coming into contact with road hazards like potholes, or sharp edged objects, or when sliding into a curb. The warranty does not cover this type of damage. Keep tires set to the correct inflation pressure and when possible, avoid contact with curbs, potholes, and other road hazards. Caution High performance summer tires have rubber compounds that lose flexibility and may develop surface cracks in the tread area at temperatures below −7 °C (20 °F). Always store high performance summer tires indoors and at temperatures above −7 °C (20 °F) when not in use.

Reduced fuel economy. Overinflated tires, or tires that have too much air, can result in: . Tire Pressure Unusual wear. . Poor handling. Tires need the correct amount of air pressure to operate effectively. . Rough ride. . Needless damage from road hazards. 343 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. See Vehicle Load Limits 0 195. 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 compact spare, if the vehicle has one. The cold compact spare tire pressure should be at 420 kPa (60 psi). See Compact Spare Tire 0 363. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 344 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. Recheck the tire pressure with the tire gauge. Warning (Continued) Put the valve caps back on the valve stems to keep out dirt and moisture and prevent leaks.

When speed limits and road conditions allow the vehicle to be driven at high speeds, make sure the tires are rated for high-speed operation, are in excellent condition, and are set to the correct cold tire inflation pressure for the vehicle load. Tire Pressure for High-Speed Operation { Warning Driving at high speeds, 160 km/h (100 mph) or higher, puts additional strain on tires. Sustained high-speed driving causes excessive heat buildup and can cause sudden tire failure. This could cause a crash, and you or others could be killed. Some high-speed rated tires require inflation pressure adjustment for high-speed (Continued) Vehicles with 235/50R18 97V or 245/45R19 98V size tires require inflation pressure adjustment when driving the vehicle at speeds of 160 km/h (100 mph) or higher.

Return the tires to the recommended cold tire inflation pressure when high-speed driving has ended. See Vehicle Load Limits 0 195 and Tire Pressure 0 343. 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. 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 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. 345 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 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 346 VEHICLE CARE See Tire Pressure Monitor Operation 0 346. See Radio Frequency Statement 0 407. 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 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 0 195. A Tire and Loading Information label, attached to your vehicle, shows the size of the original equipment tires and the correct inflation pressure for the tires when they are cold. See Vehicle Load Limits 0 195 for an example of the Tire and Loading Information label and its location. Also see Tire Pressure 0 343. 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. Using the DIC, tire pressure levels can be viewed. For additional information and details about the DIC operation and displays see Driver Information Center (DIC) 0 149. The TPMS can warn about a low tire pressure condition but it does not replace normal tire maintenance. See Tire Inspection 0 349, Tire Rotation 0 350, and Tires 0 335. 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. Caution Tire sealant materials are not all the same. A non-approved tire sealant could damage the TPMS sensors. TPMS sensor 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 VEHICLE CARE 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 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 . . . 347 light and the DIC message should go off after successfully completing the sensor matching process. See "TPMS Sensor Matching Process" later in this section. 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. 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. Tire Fill Alert (If Equipped) 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 0 352. Operating electronic devices or being near facilities using radio wave frequencies similar to the TPMS could cause the TPMS sensors to malfunction. 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 348 VEHICLE CARE 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 pressure listed on the tire sidewall. See Tire Sidewall Labeling 0 338 and Vehicle Load Limits 0 195. 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. The TPMS sensor matching process should also 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 tire. See your dealer for service or to purchase a relearn tool. A TPMS relearn tool can also be purchased. See Tire Pressure Monitor Sensor Activation Tool at Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 VEHICLE CARE 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. Place the vehicle in Service Mode. See Ignition Positions 0 200. 3. Make sure the Tire Pressure info display option is turned on. The info displays on the DIC can be turned on and off through the Options menu. See Driver Information Center (DIC) 0 149. 4. Use the five-way DIC control on the right side of the steering wheel to scroll to the Tire Pressure screen under the DIC info page. See Driver Information Center (DIC) 0 149. 5. Press and hold SEL in the center of the five-way DIC control. 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. 349 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. 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 350 VEHICLE CARE Replace the tire if: . The indicators at three or more places around the tire can be seen. . 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. 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. See When It Is Time for New Tires 0 351 and Wheel Replacement 0 355. Reset the Tire Pressure Monitor System. See Tire Pressure Monitor Operation 0 346. Check that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Specifications 0 393, and “Removing the Flat Tire and Installing the Spare Tire” under Tire Changing 0 358. Tire Rotation { Warning Tires should be rotated every 12 000 km (7,500 mi). See Maintenance Schedule 0 379. Tires are rotated to achieve a uniform wear for all tires. The first rotation is the most important. 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 0 343 and Vehicle Load Limits 0 195. Use this rotation pattern when rotating the tires. Do not include the spare tire in the tire rotation. Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after time. The wheel could come off and cause a crash.

The first two digits represent the week (01–52) and the last two digits, the year. For example, the third week of the year 2010 would have a four-digit DOT date of 0310. Warning (Continued) changing a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, a cloth or a 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 buildup. Do not get grease on the wheel mounting surface or on the wheel nuts or bolts. 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. 351 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 0 349 and Tire Rotation 0 350. 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. The 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 352 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 0 338, for additional information. GM recommends replacing worn tires in complete sets of four. 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 should wear out at about the same time. See Tire Rotation 0 350 for information on proper tire rotation. However, if it is necessary to replace only one axle set of worn tires, place the new tires on the rear axle. Winter tires with the same speed rating as the original equipment tires may not be available for H, V, W, and ZR speed rated tires. Never exceed the winter tire's maximum speed capability when using winter tires with a lower speed rating. { 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. { Warning Mixing tires of different sizes (other than those originally installed on the vehicle), brands, or types may cause loss of control of the vehicle, resulting in a crash or other vehicle damage. Use the correct size, brand, and type of tire on all four wheels. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 VEHICLE CARE { 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. 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. Vehicles that have a tire pressure monitoring system could give an inaccurate low-pressure warning if non-TPC Spec rated tires are installed. See Tire Pressure Monitor Operation 0 346. The Tire and Loading Information label indicates the original equipment tires on the vehicle. See Vehicle Load Limits 0 195. 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 (Continued) 353 Warning (Continued) 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 0 352 and Accessories and Modifications 0 288. 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) Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 354 VEHICLE CARE 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) 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 Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 VEHICLE CARE 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. 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. 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. 355 { 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 356 VEHICLE CARE 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 Caution Use tire chains only where legal and only when necessary. Use low profile chains that add no more than 10 mm thickness to the tire tread and inner sidewall. Use chains that are the proper size for the tires. Install them on the tires of the rear axle. Do not use chains on the tires of the front axle. Tighten them as tightly as possible with the ends (Continued) Caution (Continued) 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. If a Tire Goes Flat It is unusual for a tire to blow out while driving, especially if the tires are maintained properly. See Tires 0 335. 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 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 VEHICLE CARE { Warning { Warning Lifting a vehicle and getting under it to do maintenance or repairs is dangerous without the appropriate safety equipment and training.

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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 398 CUSTOMER INFORMATION 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 Cadillac Customer Assistance Center at 1-800–458–8006. In Canada, call the Canadian Cadillac Customer Care Centre at 1-888-446-2000. 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 Cadillac, 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 the 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. You may contact the BBB Auto Line Program using the toll-free telephone number or write them at the following address: The BBB Auto Line Program is an out-of-court program administered by the Council of Better Business Bureaus 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. Telephone: 1-800-955-5100 http://www.bbb.org/council/ programs-services/ dispute-handling-and-resolution/ bbb-auto-line BBB Auto Line Program Council of Better Business Bureaus, Inc. 3033 Wilson Boulevard Suite 600 Arlington, VA 22201 This program is available in all 50 states and the District of Columbia. Eligibility is limited by vehicle age, mileage, and other factors. General Motors reserves the right to change eligibility limitations and/or discontinue its participation in this program. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 CUSTOMER INFORMATION 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. For further information concerning eligibility in the Canadian Motor Vehicle Arbitration Plan (CAMVAP), call toll-free 1-800-207-0685, or call the Cadillac Customer Care Centre, 1-888-446-2000, or write to: General Motors Cadillac Customer Care Centre General Motors of Canada Company Mail Code: CA1-163-005 1908 Colonel Sam Drive Oshawa, Ontario L1H 8P7 The inquiry should be accompanied by the Vehicle Identification Number (VIN). 399 Customer Assistance Offices Cadillac encourages customers to call the toll-free number for assistance.

By scheduling a service appointment and advising the service consultant of your transportation needs, your dealer can help minimize your inconvenience. 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), extended powertrain, and/or hybrid-specific warranties in both the U.S. and Canada. 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. 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 booklet entitled “Limited Warranty and Owner Assistance Information” furnished with each new vehicle provides detailed warranty coverage information. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 404 CUSTOMER INFORMATION Transportation Options Courtesy Rental Vehicle 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: 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 usage charges, taxes, levies, usage fees, excessive mileage, or rental usage beyond the completion of the repair are also your responsibility. 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 for shuttle service. 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. It may not be possible to provide a like vehicle as a courtesy rental. Additional Program Information All program options, such as shuttle service, may not be available at every dealer. Contact your dealer for specific availability. General Motors reserves the right to unilaterally modify, change, or discontinue Courtesy Transportation at any time and to resolve all questions of claim eligibility pursuant to the terms and conditions described herein at its sole discretion. 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. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 CUSTOMER INFORMATION 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. 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 by using 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. 405 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. 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 Service 0 401. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 406 CUSTOMER INFORMATION 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 88. 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. If another party's insurance company is paying for the repairs, you are not obligated to accept a repair valuation based on that insurance company's collision policy repair limits, as you have no contractual limits with that company. In such cases, you can have control of the repair and parts choices as long as the cost stays within reasonable limits.

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. Some modules may also store data about how the vehicle is operated, such as rate of fuel consumption or average speed. These modules may retain personal preferences, such as radio presets, seat positions, and temperature settings. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 CUSTOMER INFORMATION 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 409 request by police or similar government office; as part of GM's defense of litigation through the discovery process; or, as required by law. Data that GM collects or receives may also be used for GM research needs or may be made available to 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 through the OnStar system. This includes information about the vehicle’s operation; collisions involving the vehicle; the use of the vehicle and its features; and, in certain situations, 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 0 413. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 410 CUSTOMER INFORMATION 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.

The wireless service provider must also have coverage, network capacity, reception, and technology compatible with OnStar or connected services. Service involving location information about the vehicle cannot work unless GPS signals are available, unobstructed, and compatible with the OnStar hardware. OnStar or connected services may not work if the OnStar equipment is not properly installed or it has not been properly maintained. If equipment or software is added, connected, or modified, OnStar or connected services may not work. Other problems beyond the control of OnStar — such as hills, tall buildings, tunnels, weather, electrical system design and architecture of the vehicle, damage to the vehicle in a crash, or wireless phone network congestion or jamming — may prevent service. See Radio Frequency Statement 0 407. Services for People with Disabilities Advisors provide services to help with physical disabilities and medical conditions. Press Q to help: . Locate a gas station with an attendant to pump gas. . Find a hotel, restaurant, etc., that meets accessibility needs. . Provide directions to the closest hospital or pharmacy in urgent situations. TTY Users OnStar has the ability to communicate to deaf, hard-of-hearing, or speech-impaired customers while in the vehicle. The available dealer-installed TTY system can provide in-vehicle access to all OnStar services, except Virtual Advisor and OnStar Turn-by-Turn Navigation. If equipped, TTY mode can be turned on or off by touching Settings, then Apps, and then Phone. When TTY mode is on, phone calls can be made or received with OnStar using the infotainment display. OnStar Personal Identification Number (PIN) A PIN is needed to access some OnStar services. The PIN will need to be changed the first time when speaking with an Advisor.

Languages The vehicle can be programmed to respond in multiple languages. Press Q and ask for an Advisor. Advisors are available in English, Spanish, and French. Available languages may vary by country. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 ONSTAR Potential Issues OnStar cannot perform Remote Door Unlock or Stolen Vehicle Assistance after the vehicle has been off continuously for 10 days without an ignition cycle. If the vehicle has not been started for 10 days, OnStar can contact Roadside Assistance or a locksmith to help gain access to the vehicle. Global Positioning System (GPS) . . Obstruction of the GPS can occur in a large city with tall buildings; in parking garages; around airports; in tunnels and underpasses; or in an area with very dense trees. 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. Do not place items over or near the antenna to prevent blocking cellular and GPS signal reception. Unable to Connect to OnStar Message If there is limited cellular coverage or the cellular network has reached maximum capacity, this message may come on. Press Q to try the call again or try again after driving a few miles into another cellular area. Vehicle and Power Issues OnStar services require a vehicle electrical system, wireless service, and GPS satellite technologies to be available and operating for features to 415 function properly. These systems may not operate if the battery is discharged or disconnected. Add-on Electrical Equipment The OnStar system is integrated into the electrical architecture of the vehicle. Do not add any electrical equipment. See Add-On Electrical Equipment 0 285. Added electrical equipment may interfere with the operation of the OnStar system and cause it to not operate. Vehicle Software Updates OnStar or GM may remotely deliver software updates or changes to the vehicle without further notice or consent. These updates or changes may enhance or maintain safety, security, or the operation of the vehicle or the vehicle systems. Software updates or changes may affect or erase data or settings that are stored in the vehicle, such as OnStar Hands-Free Calling name tags, saved navigation destinations, or pre-set radio stations. Neither OnStar nor GM is responsible for any affected or erased data or settings. Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-12533370) 2019 - CRC - 8/1/18 416 ONSTAR These updates or changes may also collect personal information.
