In a crash, if you or your passenger(s) are not wearing seat belts, injuries can be much worse than if you are wearing seat belts. You can be seriously injured or killed by hitting things inside the vehicle harder or by being ejected from the vehicle. In addition, anyone who is not buckled up can strike other passengers in the vehicle. It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle. In a collision, passengers riding in these (Continued) Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 46 Seats and Restraints Warning (Continued) areas are more likely to be seriously injured or killed. Do not allow passengers to travel 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 fasten the seat belts. See Seat Belt Reminders 0 94. Why Seat Belts Work When riding in a vehicle, you travel as fast as the vehicle does. If the vehicle stops suddenly, you keep going until something stops you. It could be the windscreen, 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 force of 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 chances of being conscious during and after a crash, so you can unbuckle and get out, are 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 the 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 the law in nearly every region requires seat belts to be worn. 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 60 or Infants and Young Children 0 61. Review and follow the rules for children in addition to the following rules. It is very important for all occupants to buckle up. Statistics show that unbelted people are hurt more often in crashes than those who are wearing seat belts. There are important things to know about wearing a seat belt properly. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Seats and Restraints { Warning You can be seriously injured, or even killed, by not wearing your seat belt properly. . Sit up straight and always keep your feet on the floor in front of you (if possible). . Wear the lap part of the belt low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones and you would be less likely to slide under the lap belt. If you slid under it, the belt would apply force on your abdomen. This could cause serious or even fatal injuries. . Wear the shoulder belt over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces. The shoulder belt locks if there is a sudden stop or crash. Never allow the lap or shoulder belt to become loose or twisted. 47 Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 48 Seats and Restraints 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. Never wear the shoulder belt under both arms or behind your back. Never route the lap or shoulder belt over an armrest. { Warning The seat belt can be pinched if it is routed under plastic trim on the seat, such as trim around the rear backrest folding handle or side airbag. In a crash, pinched seat belts might not provide adequate protection. Never allow seat belts to be routed under plastic trim pieces. Lap-Shoulder Belt Always use the correct buckle for your seating position. All seating positions in the vehicle have a lap-shoulder belt. 2. Pick up the latch plate and pull the belt across you. Do not let it get twisted. The lap-shoulder belt may lock if you pull the belt across you very quickly. If this happens, let the belt go back slightly to unlock it. Then pull the belt across you more slowly. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Seats and Restraints 49 To unlatch the belt, push the button on the buckle. The belt should return to its stowed position. Always stow the seat belt slowly. If the seat belt webbing returns quickly to the stowed position, the retractor may lock and cannot be pulled out. If this happens, pull the seat belt straight out firmly to unlock the webbing, and then release it. If the webbing is still locked in the retractor, see your retailer. 3. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. Position the release button on the buckle so that the seat belt could be quickly unbuckled if necessary. 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. To make the lap part tight, pull up on the shoulder belt. Before a door is closed, be sure the seat belt is out of the way. If a door is slammed against a seat belt, damage can occur to both the seat belt and the vehicle. Shoulder Belt Height Adjuster The vehicle has a shoulder belt height adjuster for the driver and front outboard passenger seating positions. Adjust the height so that the shoulder portion of the belt is on the shoulder and not falling off of it. The belt should be close to, but not contacting, the neck. Improper shoulder belt height adjustment could reduce the effectiveness of the seat belt in a crash. See How to Wear Seat Belts Properly 0 46. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 50 Seats and Restraints conditions for pretensioner activation are met. Seat belt pretensioners can also help tighten the seat belts in a side crash or roll-over 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 51. Press and hold the release button while raising or lowering the height adjuster to the desired position. After the height adjuster is set to the desired position, try to move it down without pressing the release button to make sure it has locked into position. Seat Belt Pretensioners This vehicle has seat belt pretensioners for front row and second row outboard occupants. Although the seat belt pretensioners cannot be seen, they are part of the seat belt assembly. They can help tighten the seat belts during the early stages of a moderate to severe frontal, near frontal, or rear crash if the threshold 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. 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. 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 foetus is to protect the mother. When a seat belt is worn properly, it is less likely that the foetus will be hurt in a crash. For pregnant women, as for anyone, the key to making seat belts effective is to wear them properly. 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 Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Seats and Restraints 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 it by reversing the latch plate on the webbing. If the twist cannot be corrected, ask your retailer to fix it. the system please see the dealer.

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. 51 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 retailer to have the seat belt assemblies inspected or replaced. New parts and repairs may be necessary even if the seat belt system was not being used at the time of the crash. Have the seat belt pretensioners checked if the vehicle has been in a crash, or if the airbag readiness light stays on after you start the vehicle or while you are driving. See Airbag Readiness Light 0 96. { Warning Safety procedures must be followed at all times when disposing of the vehicle or vehicle parts. Disposal should be performed only by an authorised service centre, to help protect the environment and your health. Airbag System The vehicle has the following airbags: . A frontal airbag for the driver Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 52 Seats and Restraints . A frontal airbag for the front outboard . . . . . . passenger A knee airbag for the driver. A knee airbag for the front outboard passenger. A seat-mounted side impact airbag for the driver A seat-mounted side impact airbag for the front outboard passenger A roof-rail airbag for the driver and the passenger seated directly behind the driver A roof-rail airbag for the front outboard passenger and the passenger seated directly behind the front outboard passenger All vehicle airbags have the word AIRBAG on the trim or on a label near the deployment opening. For frontal airbags, the word AIRBAG is on the centre 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 backrest or side of the seat closest to the door. For roof-rail airbags, the word AIRBAG is on the ceiling or trim. Airbags are designed to supplement the protection provided by seat belts. Even though today's airbags are also designed to help reduce the risk of injury from the force of an inflating bag, all airbags must inflate very quickly to do their job. Here are the most important things to know about the airbag system: { 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 54. (Continued) Warning (Continued) Wearing your seat belt during a crash helps reduce your chance of hitting things inside the vehicle or being ejected from it. Airbags are “supplemental restraints” to the seat belts. Everyone in the vehicle should wear a seat belt properly, whether or not there is an airbag for that person. { Warning Because airbags inflate with great force and faster than the blink of an eye, anyone who is up against, or very close to, an 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 (Continued) Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Seats and Restraints Warning (Continued) most effective when you are sitting well back and upright in the seat with both feet on the floor. 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. The system checks the airbag electrical system for malfunctions. The light tells you if there is an electrical problem. See Airbag Readiness Light 0 96. Where Are the Airbags? { Warning Children who are up against, or very close to, any airbag when it inflates can be seriously injured or killed. Always secure children properly in the vehicle. To read how, see Older Children 0 60 or Infants and Young Children 0 61. 53 The driver knee airbag is below the steering column. The front outboard passenger knee airbag is below the glove box. The driver frontal airbag is in the centre of the steering wheel. The front outboard passenger frontal airbag is in the passenger side instrument panel. There is an airbag readiness light on the instrument cluster, which shows the airbag symbol. Driver Side Shown, Passenger Side Similar Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 54 Seats and Restraints The driver and front outboard passenger seat-mounted side impact airbags are in the sides of the seatbacks closest to the door. Warning (Continued) must be kept clear. Do not put anything between an occupant and an airbag, and do not attach or put anything on the steering wheel hub or on or near any other airbag covering. Do not use seat accessories that block the inflation path of a seat-mounted side impact airbag. Driver Side 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. { Warning If something is between an occupant and an airbag, the airbag might not inflate properly or it might force the object into that person causing severe injury or even death. The path of an inflating airbag (Continued) Never secure anything to the roof of a vehicle with roof-rail airbags by routing a rope or tie-down through any door or window opening. If you do, the path of an inflating roof-rail airbag will be blocked. When Should an Airbag Inflate? This vehicle is equipped with airbags. See Airbag System 0 51. 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 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 travelling. It depends on what is hit, the direction of the impact, and how quickly the vehicle slows down. Frontal airbags may inflate at different crash speeds depending on whether the vehicle hits an object straight on or at an angle, and whether the object is fixed or moving, rigid or deformable, narrow or wide. Frontal airbags are not intended to inflate during vehicle rollovers, rear impacts, or many side impacts. In addition, the vehicle has advanced technology frontal airbags. Advanced technology frontal airbags adjust the restraint according to crash severity. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Seats and Restraints Knee airbags are designed to inflate in moderate to severe frontal impacts. Knee airbags are not designed to inflate during vehicle rollovers, in rear impacts, or in many side impacts. Seat-mounted side impact airbags are designed to inflate in moderate to severe side crashes depending on the location of the impact. These airbags may also inflate in some moderate to severe frontal impacts. Seat-mounted side impact airbags are not designed to inflate in 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 may inflate during a rollover or in a severe frontal impact. Roof-rail airbags are not designed to inflate in rear impacts. Both roof-rail airbags may inflate when either side of the vehicle is struck or if the sensing system predicts that the vehicle is about to roll over on its side, or in a severe frontal impact. In any particular crash, no one can say whether an airbag should have inflated simply because of the vehicle damage or the repair costs. What Makes an Airbag Inflate? In a deployment event, the sensing system sends an electrical signal triggering a release of gas from the inflator. Gas from the inflator fills the airbag causing the bag to break out of the cover. The inflator, the airbag, and related hardware are all part of the airbag module. For airbag locations, see Where Are the Airbags? 0 53. 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. 55 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 54. 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 realise the airbags inflated. Roof-rail airbags may still be at least partially inflated for some time after deployment. Some components of the airbag module may be hot for several minutes. For location of the airbags, see Where Are the Airbags? 0 53. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 56 Seats and Restraints 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 windscreen 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 should leave the vehicle 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 lights, 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, windscreens are broken by vehicle deformation. Additional windscreen 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 0 346. . 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. Airbag On-Off Switch If the instrument panel has the switch pictured in the following illustration, the vehicle has an airbag on-off switch that you Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Seats and Restraints can use to manually turn the front outboard passenger airbag on or off. No other airbag is affected by the airbag on-off switch. This switch should only be turned to the OFF position if the person in the front outboard passenger position belongs to a category indicated in this section: Infant. An infant (less than 1 year old) must travel in the front seat because: . My vehicle has no rear seat; . My vehicle has a rear seat too small to accommodate a rear-facing infant seat; or . The infant has a medical condition which, according to the infant's physician, makes it necessary for the infant to ride in the front seat so that the driver can constantly monitor the child's condition. Child age 1 to 12. A child age 1 to 12 must travel in the front seat because: . My vehicle has no rear seat; . Although children ages 1 to 12 ride in the rear seat(s) whenever possible, children ages 1 to 12 sometimes must travel in the front because no space is available in the rear seat(s) of my vehicle; or . The child has a medical condition which, according to the child's physician, makes it necessary for the child to travel in the front seat so that the driver can constantly monitor the child's condition. Medical Condition. A passenger has a medical condition which, according to his or her physician: . Causes the passenger airbag to pose a special risk for the passenger; and . Makes the potential harm from the passenger airbag in a crash greater than the potential harm from turning off the 57 airbag and allowing the passenger, even if belted, to hit the instrument panel or windscreen in a crash. { Warning If the front outboard passenger frontal airbag is turned off for a person who does not belong to a category indicated in this section, that person will not have the extra protection of an airbag. In a crash, the airbag will not be able to inflate and help protect the person sitting there. Do not turn off the front outboard passenger frontal airbag unless the person sitting there belongs to a category indicated in this section. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 58 Seats and Restraints Warning (Continued) system. For example, the front outboard passenger frontal airbag could inflate even though the airbag on-off switch is turned off. To help avoid injury to yourself or others, have the vehicle serviced right away. See Airbag Readiness Light 0 96 for more information, including important safety information. To turn off the front outboard passenger frontal airbag, insert the ignition key into the airbag on-off switch, push in, and move the switch to the OFF position. Servicing the Airbag-Equipped Vehicle Airbags affect how the vehicle should be serviced. There are parts of the airbag system in several places around the vehicle. Your dealer and the service manual have information about servicing the vehicle and the airbag system. { Warning The airbag off light will come on and stay on to let you know the front outboard passenger airbag is turned off. See Airbag On-Off Light 0 96. The front outboard passenger airbag will remain turned off until you turn it back on again. { Warning If the airbag readiness light ever comes on and stays on, it means that something may be wrong with the airbag (Continued) The front outboard passenger frontal airbag is now enabled, and may inflate. See Airbag On-Off Light 0 96. To turn the front outboard passenger airbag on again, insert the ignition key into the airbag on-off switch, push in, and move the switch to the ON position. For up to 10 seconds after the vehicle is turned off and the battery is disconnected, an airbag can still inflate during improper service. You can be injured if you are close to an airbag when it inflates. Avoid yellow connectors. They are probably part of the airbag system. Be sure to follow proper service procedures, and make sure the person performing work for you is qualified to do so. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Seats and Restraints { Warning Safety procedures must be followed at all times when disposing of the vehicle or vehicle parts. Disposal should be performed only by an authorised service centre, to help protect the environment and your health. Adding Equipment to the Airbag-Equipped Vehicle Adding accessories that change the vehicle's frame, bumper system, height, front end, or side sheet metal may keep the airbag system from working properly. The operation of the airbag system can also be affected by changing, including improperly repairing or replacing, any parts of the following: . Airbag system, including airbag modules, front or side impact sensors, sensing and diagnostic module, or airbag wiring . Front seats, including stitching, seams or zip fasteners . Seat belts . Steering wheel, instrument panel, overhead console, ceiling trim, or pillar garnish trim .

Child Restraints Older Children { Warning Safety procedures must be followed at all times when disposing of the vehicle or vehicle parts. Disposal should be performed only by an authorised service centre, to help protect the environment and your health. . Fasten the lap-shoulder belt. Does the shoulder belt rest on the shoulder? If yes, continue. If no, then return to the booster seat. . Does the lap belt fit low and snug on the hips, touching the thighs? If yes, continue. If no, return to the booster seat. . Can proper seat belt fit be maintained for the length of the trip? If yes, continue. If no, return to the booster seat. Q: What is the proper way to wear seat belts? Older children who have outgrown booster seats should wear the vehicle's seat belts. Refer to How to Wear Seat Belts Properly 0 46. The manufacturer instructions that come with the booster seat state the weight and height limitations for that booster. Use a booster seat with a lap-shoulder belt until the child passes the fit test below: . Sit all the way back on the seat. Do the knees bend at the seat edge? If yes, continue. If no, return to the booster seat. A: An older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck. The lap belt should fit snugly below the hips, just touching the top of the thighs. This applies belt force to the child's pelvic bones in a crash. It should never be worn over the abdomen, which could cause severe or even fatal internal injuries in a crash. According to accident statistics, children are safer when properly restrained in a rear seating position. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Seats and Restraints In a crash, children who are not buckled up can strike other people who are buckled up, or can be thrown out of the vehicle. Older children need to use seat belts properly. { Warning Never allow more than one child to wear the same seat belt. The seat belt cannot properly spread the impact forces. In a crash, they can be crushed together and seriously injured. A seat belt must be used by only one person at a time. 61 { Warning Never allow a child to wear the shoulder belt of the seat belt under both arms or behind their back. A child can be seriously injured by not wearing the lap-shoulder belt properly. In a crash, the child would not be restrained by the shoulder belt. The child could move too far forward increasing the chance of head and neck injury. The child might also slide under the lap belt. The belt force would then be applied right on the abdomen. That could cause serious or fatal injuries. The shoulder belt should go over the shoulder and across the chest. Infants and Young Children Everyone in a vehicle needs protection! This includes infants and all other children. Neither the distance travelled nor the age and size of the traveller changes the need, for everyone, to use safety restraints. { Warning Children can be seriously injured or killed if the shoulder belt is worn behind their back, under their legs, or wrapped around their neck. Never leave children unattended in a vehicle and never allow children to improperly wear, or play with, the seat belts. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 62 Seats and Restraints 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. For example, in a crash at only 40 km/h (25 mph), a 5.5 kg (12 lb) infant will suddenly become a 110 kg (240 lb) force on a person's arms. An infant or child should be secured in an appropriate child restraint. { Warning Children who are up against, or very close to, any airbag when it inflates can be seriously injured or killed. Never put a rear-facing child restraint in the front 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. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Seats and Restraints 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. The instruction manual that is provided with the child restraint states the weight and height limitations for that particular child restraint. In addition, there are many kinds of child restraints available for children with special needs. { 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. { Warning A young child's hip bones are still so small that the vehicle seat belt may not remain low on the hip bones, as it should. Instead, it may settle up around the child's abdomen. In a crash, the belt would apply force on a body area that is (Continued) Warning (Continued) unprotected by any bony structure. This alone could cause serious or fatal injuries. To reduce the risk of serious or fatal injuries during a crash, young children should always be secured in an appropriate child restraint. Child Restraint Systems Infants and children should be placed in the rear seat and properly restrained, according to the terms in this manual. A young child's hip bones are so small that the vehicle's regular seat belt may not remain low on the hip bones, as it should. Instead, there is a possibility that it will load the abdomen and cause serious or fatal injury in a crash. 63 { Danger NEVER use a rearward-facing child restraint on a seat protected by an ACTIVE AIRBAG in front of it; DEATH or SERIOUS INJURY to the CHILD can occur. { Danger If using a rear-facing child restraint on the front passenger seat, the airbag for the front passenger seat must be deactivated. This also applies to certain forward-facing child restraints as indicated in the tables listed in this manual. See Airbag On-Off Switch 0 56. When a child restraint is being used, pay attention to the following usage and installation instructions and also those supplied with the child restraint. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 64 Seats and Restraints Always comply with local or national regulations. In some countries, the use of child restraints is forbidden on certain seats. Group Weight Class Group 0 Up to 10 kg (22 lb) Group 0+ Up to 13 kg (28 lb) Group I 9 to 18 kg (20 to 39 lb) Group II 15 to 25 kg (34 to 55 lb) Group III 22 to 36 kg (49 to 79 lb) Model B : Group I – Child Seat Model C : Group II and III – Booster Seat Child restraints are designed to be fastened with the lap-shoulder belt or the ISOFIX anchors. Some child restraints also use a top tether or support leg. Child Restraint Classification For reference, child restraints available in the market are classified based on the child's mass. Carefully observe the installation and usage instructions given by the child restraint manufacturer. When choosing a child restraint, it is important to consider the child's height in addition to its age and mass. { Danger . Make sure that the child restraint is installed properly. If the child restraint is not properly attached, the risk of serious injury in the event of a collision increases. . Do not attach or place objects or other materials on the child restraint. (Continued) Model A : Group 0 and 0+ – Baby Seat Danger (Continued) . Do not leave any loose objects in the vehicle. During an impact, an object may move and cause injuries to the occupants. . After a crash, it is necessary to replace the child restraint because it may have suffered non-visible damage. . Always restrain your child in a properly installed child restraint, even on short trips. . Allow children to enter and exit the vehicle only on the side facing away from traffic. { Warning . When carrying a child, follow the procedures for the transport of children established by the local laws. . In some countries, the use of child restraints is forbidden on certain seats. . After removing the child from the vehicle, keep the child restraint attached with the seat belt or ISOFIX, (Continued) Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Seats and Restraints Warning (Continued) in order to avoid the child restraint from being thrown forward in case of sudden braking. Make sure that the child restraint: . Is installed in accordance with the instructions given by the child restraint manufacturer. . Has the label of approval of safety regulations certification, in terms of the local laws. . Is suitable for your vehicle. Selecting the Right Child Restraint The rear seats are the most convenient location to fasten a child restraint. Children should travel facing rearward in the vehicle to as late an age as possible. This makes sure that the child's backbone, which is still very weak, is under less strain in the event of a crash. General Motors recommends using a genuine GM child restraint. Ensure that the child restraint to be installed is compatible with the vehicle type. 65 Make sure that the mounting location of the child restraint within the vehicle is correct as per the tables included in this manual. See Where to Put the Restraint 0 65. The provisions established by the laws have priority over the provisions of this manual. { Danger Never use a single seat belt with an adult and a child. During an impact, the seat belt will exert strong pressure on the child, causing serious or fatal injury. Never allow two children to share the same seat belt. Both could suffer serious injuries in a crash. { Danger 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. Infants and children must never be carried on the lap of another occupant. Whenever possible, children aged 12 and under should be secured in a rear seating position. Although an infant does not weigh much, it will be so heavy during a crash that it will be impossible to hold it, even if the occupant is attached to the seat belt. 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. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 66 Seats and Restraints { Danger NEVER use a rearward-facing child restraint on a seat protected by an ACTIVE AIRBAG in front of it; DEATH or SERIOUS INJURY to the CHILD can occur. { Danger When using a child restraint on the front passenger seat, the airbag systems for the front passenger seat must be deactivated; if not, the triggering of the airbags poses a risk of fatal injury to the child.

Try to move the head restraint to make sure that it is locked in place. Securing Child Restraints (With the Seat Belt in the Rear Seat) 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. If the child restraint has the ISOFIX system, see ISOFIX Child Restraint Systems 0 71 for how and where to install the child restraint using ISOFIX. If a child restraint is secured in the vehicle using a seat belt and it uses a top tether, see ISOFIX Child Restraint Systems 0 71 for top tether anchor locations. If more than one child restraint needs to be installed in the rear seat, be sure to read Where to Put the Restraint 0 65. 1. Put the child restraint on the seat. 2. Pick up the latch plate and run the lap and shoulder portions of the vehicle seat belt through or around the child restraint. Ensure the seat belt webbing is routed as directly as possible and is not caught on seat handles or plastic trim. The child restraint instructions will show you how. Do not secure a child seat in a position without a top tether anchor if a national or local law requires that the top tether be anchored, or if the instructions that come with the child restraint state that the top tether must be anchored. If the child restraint or vehicle seat position does not have the ISOFIX system, you will be using the seat belt to secure the child restraint. Be sure to follow the instructions that came with the child restraint. 3. Push the latch plate into the buckle until it clicks. Position the release button on the buckle, away from the child restraint, so that the seat belt can be quickly unbuckled if necessary. There must not be direct contact between the child restraint and the push button. 4. Follow the instructions in the child restraint owner's manual to tighten and lock the child restraint using the vehicle seat belt. 5. If the child restraint has a top tether, follow the child restraint manufacturer's instructions regarding the use of the top tether. See ISOFIX Child Restraint Systems 0 71. 6. Before placing a child in the child restraint, make sure it is securely held in place. Refer to your child restraint manufacturer's instructions. To remove the child restraint, follow the instructions in the child restraint owner's manual to unlock it. Unfasten the vehicle seat belt and let it return to the stowed position. If the top tether is attached to a top tether anchor, disconnect it. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Seats and Restraints Securing Child Restraints (With the Seat Belt in the Front Seat) This vehicle has airbags. A rear seat is a safer place to secure a forward-facing child restraint. See Where to Put the Restraint 0 65. There may be a switch on the instrument panel that you can use to turn off the front outboard passenger frontal airbag. See Airbag On-Off Switch 0 56 for more information, including important safety information. Danger (Continued) This is especially the case if rear-facing child restraints are used on the front passenger seat. { Warning { Danger A child in a rear-facing child restraint can be seriously injured or killed if the front outboard 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 outboard passenger airbag inflates and the passenger seat is in a forward position. When using a child restraint on the front passenger seat, the airbag systems for the front passenger seat must be deactivated; if not, the triggering of the airbags poses a risk of fatal injury to the child. (Continued) Even if the airbag switch has turned off the front outboard 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. (Continued) 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. 75 Warning (Continued) 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 outboard passenger seat, always move the seat as far back as it will go. It is better to secure the child restraint in a rear seat. { Warning If the airbag readiness light ever comes on and stays on, it means that something may be wrong with the airbag system. For example, the front outboard passenger frontal airbag could inflate even though the airbag on-off switch is turned off. To help avoid injury to yourself or others, have the vehicle serviced right away. See Airbag Readiness Light 0 96 for more information, including important safety information. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 76 Seats and Restraints If the child restraint uses a top tether, see ISOFIX Child Restraint Systems 0 71 for top tether anchor locations. 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 must be anchored, or if the instructions that come with the child restraint say that the top tether must be anchored. When using the lap-shoulder belt to secure the child restraint in this position, follow the instructions that came with the child restraint and the following instructions: 1. Move the seat as far back as it will go before securing the forward-facing child restraint. Move the seat upward or the backrest to an upright position, if needed, to get a tight installation of the child restraint. There must be finger clearance between the push button and the child restraint. When the airbag off switch has turned off the front outboard passenger frontal airbag, the off indicator in the airbag off light should illuminate and remain illuminated when you start the vehicle. See Airbag On-Off Light 0 96. 2. Put the child restraint on the seat. 3. Pick up the latch plate and run the lap and shoulder portions of the vehicle seat belt through or around the restraint. Ensure the seat belt webbing is routed as direct as possible and is not caught on seat handles or plastic trim. The child restraint instructions will show you how. 4. Push the latch plate into the buckle until it clicks. Position the release button on the buckle, away from the child restraint, so that the seat belt can be quickly unbuckled if necessary. 5. Follow the instructions in the child restraint owner's manual to tighten and lock the child restraint when using the vehicle seat belt. 6. If the child restraint has a top tether, follow the child restraint manufacturer's instructions regarding the use of the top tether. See ISOFIX Child Restraint Systems 0 71. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Seats and Restraints If the airbags are off, the off indicator in the passenger airbag status indicator will come on and stay on when the vehicle is started. To remove the child restraint, unbuckle the vehicle seat belt and let it return to the stowed position. If the top tether is attached to a top tether anchor, disconnect it. If you turned the airbag off with the switch, turn on the front outboard passenger airbag when you remove the child restraint from the vehicle unless the person who will be sitting there is a member of a passenger airbag risk group. See Airbag On-Off Switch 0 56 for more information, including important safety information. 77 Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 78 Storage Storage Storage Compartments { Warning Storage Compartments Storage Compartments . . . . . . . . . . . . . . . . . 78 Glove Box . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 78 Front Storage . . . . . . . . . . . . . . . . . . . . . . . . . . . 78 Sunglasses Storage . . . . . . . . . . . . . . . . . . . . . 79 Armrest Storage . . . . . . . . . . . . . . . . . . . . . . . . 79 Rear Storage . . . . . . . . . . . . . . . . . . . . . . . . . . . 79 Centre Console Storage . . . . . . . . . . . . . . . . 80 Umbrella Storage . . . . . . . . . . . . . . . . . . . . . . . 81 Front Storage Do not store heavy or sharp objects in storage compartments.

Cargo must be secured with properly installed cross rails and other accessories designed to carry cargo. These can be purchased from your dealer. Do not exceed the maximum cargo weight for the roof rack system, which includes the weight of the cross rails and any other accessories used to carry the cargo such as bike racks or roof boxes. The maximum cargo weight that can be loaded onto the roof rack system is 100 kg (220 lb) or the weight designated in the instructions that came with the cross rails or other roof rack accessories, whichever is less. { Warning Before driving and occasionally during a trip, check that the cargo is securely fastened, that it rests evenly between the cross rails and does not block the vehicle's lights or windows. Never load cargo directly on the roof of the vehicle or allow cargo to hang over the rear or sides of the vehicle. Never load cargo without first properly installing cross rails and other accessories designed to carry cargo. Personal injury, death or damage to the vehicle or other property may occur. If driving for a long distance, on rough roads, or at high speeds, occasionally stop the vehicle to make sure the cargo remains in its place. { Warning Never load the roof rack with more weight than specified in this section. Loading cargo on the roof rack will make the vehicle's centre of gravity higher. To avoid losing control of the vehicle, avoid overloading, high speeds, sudden starts, sharp turns, sudden braking, or abrupt manoeuvres when carrying cargo on the roof rack.

Display text from radio stations that include station name and messages. This system relies on receiving specific information from these stations and only works when the information is available. It is possible that a radio station could broadcast incorrect information that causes the radio features to work improperly. If this happens, contact the radio station. When information is broadcast from an RDS station, the station name or call letters display on the audio screen. Radio text supporting the currently playing broadcast may also appear. Radio Reception Unplug electronic devices from the accessory power outlets if there is interference or static in the radio. FM FM signals only extend about 16 to 65 km (10 to 40 mi). Although the radio has a built-in electronic circuit that automatically works to reduce interference, some static can occur, especially around tall buildings or hills, causing the sound to fade in and out. AM Multi-Band Aerial The range for most AM stations is greater than for FM, especially at night. The longer range can cause station frequencies to interfere with each other. Static can also occur when things like storms and power lines interfere with radio reception. When this happens, try reducing the treble on the radio. The multi-band roof aerial may be used for radio, navigation, and other communication systems, depending on the equipped options. To ensure clear reception, keep the aerial clear of obstructions, such as snow and ice. If the vehicle has a sunroof, and it is open, or a roof loaded with cargo, reception may be affected. Digital Audio Broadcasting (DAB) If equipped, Digital Audio Broadcasting (DAB) is a universal broadcast system that shows stations by the radio programme name on the infotainment display. The DAB signal produces a constant volume and is not affected by interference from nearby frequencies. The reception quality of DAB improves if the signal is reflected by natural obstacles or buildings. If the DAB signal is unclear, reception is interrupted completely. Mobile Phone Usage Mobile phone usage, such as making or receiving phone calls, charging, or just having the phone on may cause static interference in the radio. Unplug the phone or turn it off if this happens. Audio Players Avoiding Untrusted Media Devices When using media devices such as USB and mobile devices, consider the source. Untrusted media devices could contain files that affect system operation or performance and should be avoided. USB Port Audio stored on a USB device may be listened to.

At times, other interference such as the satellite condition, road configuration, condition of the vehicle, and/or other circumstances can affect the navigation system's ability to determine the accurate position of the vehicle. The GPS shows the current position of the vehicle using signals sent by GPS satellites. When the vehicle is not receiving signals from the satellites, a symbol appears in the status bar. This system might not be available or interference can occur if any of the following are true: . Signals are obstructed by tall buildings, trees, large trucks, or a tunnel. . Satellites are being repaired or improved. For more information if the GPS is not functioning properly, see Problems with Route Guidance 0 142 and If the System Needs Service 0 142. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 142 Infotainment System Vehicle Positioning At times, the position of the vehicle on the map could be inaccurate due to one or more of the following reasons: . The road system has changed. . The vehicle is driving on slippery road surfaces such as sand, gravel, or snow. . The vehicle is travelling on winding roads or long, straight roads. . The vehicle is approaching a tall building or a large vehicle. . The surface streets run parallel to a freeway. . The vehicle has been transferred by a vehicle carrier or a ferry. . The current position calibration is set incorrectly. . The vehicle is travelling at high speed. . The vehicle changes directions more than once, or the vehicle is turning on a turn table in a car park. . The vehicle is entering and/or exiting a car park, garage, or a car park with a roof. . The GPS signal is not received. . A roof carrier is installed on the vehicle. . Tire chains are installed on the vehicle. . The tyres are replaced or worn. . The tyre pressure is incorrect. . This is the first navigation use after the map data is updated. . The 12-volt battery has been disconnected for several days. . The vehicle is driving in heavy traffic where driving is at low speeds, and the vehicle is stopped and started repeatedly. Problems with Route Guidance Inappropriate route guidance can occur under one or more of the following conditions: . The turn was not made on the road indicated. . Route guidance might not be available when using automatic rerouting for the next right or left turn. . The route might not be changed when using automatic rerouting. . There is no route guidance when turning at an intersection. . Plural names of places might be announced occasionally. . It could take a long time to operate automatic rerouting during high-speed driving. . Automatic rerouting might display a route returning to the set waypoint if heading for a destination without passing through a set waypoint. . The route prohibits the entry of a vehicle due to a regulation by time or season or any other regulation which may be given. . Some routes might not be searched. . The route to the destination might not be shown if there are new roads, if roads have recently changed, or if certain roads are not listed in the map data. See Maps 0 135. To recalibrate the vehicle's position on the map, park with the vehicle running for two to five minutes, until the vehicle position updates. Make sure the vehicle is parked in a location that is safe and has a clear view of the sky and away from large obstructions. If the System Needs Service If the navigation system needs service, see your dealer. Map Data Updates The map data in the vehicle is the most up-to-date information available when the vehicle was produced. The map data is Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Infotainment System updated periodically, provided that the map information has changed and the vehicle has a relevant service plan. See your retailer for details on ordering, purchasing, and installing a new or replacement SD card. Features are subject to change. If the vehicle is equipped with Connected Navigation, which is a subscription service that enables certain features of the navigation system, such as Traffic, Smart Search/Routing, and Predictive Navigation, then the system will download the latest map data from the cloud. Database Coverage Explanations Coverage areas vary with respect to the level of map detail available for any given area. Some areas feature greater levels of detail than others. If this happens, it does not mean there is a problem with the system. As the map data is updated, more detail can become available for areas that previously had limited detail. See Map Data Updates 0 142. Voice Recognition If equipped, voice recognition allows hands-free operation within the navigation, audio, and mobile device applications. This feature can be started by pressing g on the steering wheel or by touching g on the infotainment display with the navigation application. However, not all features within these areas are supported by voice commands. Generally, only complex tasks that require multiple manual interactions to complete are supported by voice commands. For example, tasks that take more than one or two touches, such as a song or artist to play from a media device, would be supported by voice commands. Other tasks, like adjusting the volume or seeking up or down, are audio features that are easily performed by touching one or two options, and are not supported by voice commands. In general there are flexible ways to speak commands for completing the tasks. Try stating a One-Shot command, such as “Directions to address .” Another example of a One-Shot Destination Entry command is, “Directions to 143 Place of Interest at .” If these commands do not work, try saying, “Take me to Place of Interest” or “Find address” and the system will walk you through by asking additional questions. Using Voice Recognition Voice recognition becomes available once the system has been initialised. This begins when the ignition is turned on. Initialisation may take a few moments. 1. Press g on the steering wheel controls to activate voice recognition. 2. The audio system mutes and the system plays a prompt. 3. Clearly speak one of the commands described in this section. A voice recognition system prompt can be interrupted while it is playing by pressing g again. For example, if the prompt seems to be taking too long to finish, speak the command without waiting for the prompt to complete and press g again. Once voice recognition is started, both the infotainment display and instrument cluster show the selections and visual dialogue Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 144 Infotainment System content. These displays can be turned on or off in the Tutorial Mode under Settings 0 153. There are three voice prompt modes supported: . Informative verbal prompts: This type of prompt will provide more information regarding the supported actions. . Short prompts: This type of prompt will provide simple instructions about what can be stated. . Auto informative prompts: This type of prompt plays during the first few speech sessions, then automatically switches to the short prompt after some experience has been gained through using the system. If a command is not spoken, the voice recognition system says a help prompt. Prompts and Infotainment Displays While a voice recognition session is active, there may be corresponding options showing on the displays. A selection can be made by manually touching the option, or by speaking the number for the option to select. Manual interaction in the voice recognition session is permitted. Interaction during a voice session may be completed entirely using voice commands while some manual commands may expedite a task. If a selection is made using a manual control, the voice recognition dialogue will progress in the same way as if the selection were made using a voice command. Once the system completes the task, or the session is terminated, the voice recognition dialogue stops. An example of this type of manual intervention is touching an entry of a displayed number list instead of speaking the number associated with the entry desired. Cancelling Voice Recognition . Touch or say “Cancel” or “Exit” to terminate the voice recognition session and show the display where voice recognition was initiated. i on the steering wheel controls to terminate the voice recognition session and show the display where voice recognition was initiated. . Press Natural Language Commands Most languages do not support natural language commands in sentence form. For those languages, use direct commands like the examples shown on the display. Helpful Hints for Speaking Commands Voice recognition can understand commands that are naturally stated in sentence form or direct commands that state the application and the task. For best results: . Listen for the prompt before saying a command or reply. . Speak the command naturally, not too fast, not too slow. . Use direct commands without a lot of extra words. For example, “Call at work,” “Play” followed by the artist or song name, or “Tune” followed by the radio station number. . Navigation destinations can be made in a single command using keywords. A few examples are: “I want directions to an address,” “I need to find a Place of Interest or (POI),” or “Find contact.” The system responds by requesting more details. For other POIs, say the name of a category like “Restaurants,” “Shopping Malls,” or “Hospitals.” . Navigating to a destination outside of the current country takes more than one command. The first command is to tell the system where the navigation will take Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Infotainment System place, such as an Address, Junction, POI, or Contact. If Address or Junction is selected, the second command is to say, “Change Country.” Once the system responds, say the country before saying the rest of the address and/or junction. If POI is asked for, say “Change Location,” then “Change Country.” Direct commands might be more clearly understood by the system. An example of a direct command would be “Call ”. Examples of these direct commands are displayed on most of the screens while a voice session is active. If “Phone” or “Phone Commands” is spoken, the system understands that a phone call is requested and will respond with questions until enough details are gathered to make a call. If a mobile phone number has been saved with a name and a place, the direct command should include both, for example “Call at work.” Using Voice Recognition for List Options When a list is displayed, a voice prompt will ask to confirm or select an option from that list. When a display contains a list, there may be options that are available but not displayed. The list on a voice recognition screen functions the same as a list on other displays. Scrolling or flinging can be used to help display other entries from the list. Manually scrolling or paging the list on a display during a voice recognition session suspends the current voice recognition event and plays the prompt “Please select manually or touch the Back icon on the infotainment display to try again.” If manual selection takes more than 15 seconds, the session terminates and prompts that it has timed out. The display returns to the screen where voice recognition was initiated. The Back Command Say “Back” or touch the Back icon on the infotainment display to go to the previous display. If in voice recognition, and “Back” is spoken all the way back to the starting display, and then “Back” is spoken one more time, the voice recognition session will cancel. 145 Help Say “Help” on any voice recognition display and the help prompt for the display is played. Touching g while the help prompt is playing will terminate the prompt. Doing this will stop the help prompt so that a voice command can be used. Voice Recognition for the Radio If browsing the audio sources when voice is touched, the voice recognition commands for AM, FM, and DAB (if equipped) are available. “Switch to AM” : Switch bands to AM and tune to the last AM radio station. “Switch to FM” : Switch bands to FM and tune to the last FM radio station. “Switch to DAB” : Switch bands to DAB and tune to the last DAB radio station. “Tune to AM” : Tune to the radio station whose frequency is identified in the command (like “nine fifty”). “Tune to FM” : Tune to the radio station whose frequency is identified in the command (like "one oh one point one"). Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 146 Infotainment System “Tune to DAB” : Tune to the radio station name. Voice Recognition for Audio MyMedia The available voice recognition commands for [browsing] MyMedia are: “Play Artist” : Begin a dialogue to enter a specific artist name. “Play Artist ” : Begin playback of a specific artist. “Play Album” : Begin a dialogue to enter a specific album name. “Play Album ” : Begin playback of a specific album. “Play Song” : Begin a dialogue to enter a specific song name. “Play Song ” : Begin playback of a specific song, if available. “Play Genre” : Begin a dialogue to enter a specific genre. “Play Genre ” : Begin playback of a specific genre. “Play Playlist” : Begin a dialogue to enter a specific playlist name. “Play Playlist ” : Begin playback of a specific playlist. “Play ” : Play music from a specific device identified by name. The device name is the name displayed when the device is first selected as an audio source. “Play Chapter” : Begin a dialogue to enter a specific name. “Play Chapter ” : Begin playback of a specific chapter. “Play Audiobook” : Begin a dialogue to enter a specific audiobook. “Play Audiobook ” : Begin playback of a specific audiobook. “Play Episode” : Begin a dialogue to enter a specific name. “Play Episode ” : Begin playback of a specific episode. “Play Podcast” : Begin a dialogue to enter a specific podcast. “Play Podcast ” : Begin playback of a specific podcast. “My Media” : Begin a dialogue to enter the desired media content. Handling Large Amounts of Media Content It is expected that large amounts of media content will be brought into the vehicle. It may be necessary to handle large amounts of media content in a different way than smaller amounts of media. The system may limit the options of voice recognition by not allowing selection of files by voice at the highest level if the number of files exceeds the maximum limit. Changes to voice commands due to media content limits are: . Files, including other individual files of all media types such as songs, audiobook chapters, podcast episodes, and videos. . Album type folders including types such as albums and audiobooks. There are no restrictions if the number of files and albums is fewer than 12,000. When the number of files connected to the system is between 12,000 and 24,000, the content cannot be accessed directly with one command like “Play .” The restriction is that the command “Play Song” must be spoken first; the system will then ask for the song name. The reply command would be to say the name of the song to play. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Infotainment System Similar limits exist for album content. If there are more than 12,000 albums, but fewer than 24,000, the content cannot be accessed directly with one command like, “Play .” The command “Play Album” must first be spoken; the system will then ask for the album name. The reply would be to say the name of the album to play. Once the number of files has exceeded approximately 24,000, there is no support for accessing the songs directly through voice commands. There will still be access to the media content by using commands for playlists, artists, and genres. The access commands for playlists, artists, and genres are prohibited after the number of this type of media exceeds 12,000. The system will provide feedback the first time voice recognition is initiated if it has become apparent that any of these limits are reached during a device initialising process. Voice recognition performance will degrade to some extent based on many factors when adding large amounts of data to recognise. If so, accessing songs through playlists or artist name may work better. Voice Recognition for Navigation (If Equipped) “Navigation” : Begin a dialogue to enter specific destination information. “Navigation Commands” : Begin a dialogue to enter specific destination information. “Address” : Begin a dialogue to enter a specific destination address, which includes the entire address consisting of the house number, street name, city and country. “Place of Interest” : Begin a dialogue to enter a destination Place of Interest category or major brand name. 147 Voice Recognition for the Phone “Call ” : Initiate a call to a stored contact. The command may include location if the contact has location numbers stored. “Call At Home,” “At Work,” “On Mobile,” or “On Other” : Initiate a call to a stored contact and location at home, at work, on mobile device, or on another phone. “Call ” : Initiate a call to a mobile phone number of seven digits, 10 digits, or three digit emergency numbers. The name must be precisely spoken. Nicknames or short names for the businesses will not likely be found. Lesser known businesses might have to be located by category, such as fast food, hotels, or banks. “Pair Phone” : Begin the Bluetooth pairing process. Follow the instructions on the infotainment display. “Navigate to Contact” : Begin a dialogue to enter a specific destination contact name. “Switch Phone” : Select a different connected mobile phone for outgoing calls. “Cancel Navigation” : End route guidance. “Voice Keypad” : Begin a dialogue to enter special numbers like international numbers. The numbers can be entered in groups of digits with each group of digits being repeated back by the system. If the group of digits is not correct, the command “Take Me Home” : Create a route to a stored home location. “Redial” : Initiate a call to the last dialled number. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 148 Infotainment System “Delete” will remove the last group of digits and allow them to be re-entered. Once the entire number has been entered, the command “Call” will start dialling the number.

Exercise good judgement and do not let other activities divert your attention away from the road. Many local governments have enacted laws regarding driver distraction. Become familiar with the local laws in your area. Driving habits can affect fuel mileage. Here are some driving tips to get the best fuel economy possible. . Set the climate controls to the desired temperature after the engine is started, or turn them off when not required. . On AWD vehicles, use Tour Mode when conditions permit. . Avoid fast starts and accelerate smoothly. . Brake gradually and avoid abrupt stops. . Avoid idling the engine for long periods of time. . When road and weather conditions are appropriate, use cruise control. . Always follow posted speed limits or drive more slowly when conditions require. . Keep vehicle tyres properly inflated. . Combine several trips into a single trip. . Replace the vehicle's tyres with the same TPC Spec number moulded into the tyre's sidewall near the size. . Follow recommended scheduled maintenance. To avoid distracted driving, keep your eyes on the road, keep your hands on the steering wheel, and focus your attention on driving. . Do not use a phone in demanding driving situations. Use a hands-free method to place or receive necessary phone calls. . Watch the road. Do not read, take notes, or look up information on phones or other electronic devices. . Designate a front seat passenger to handle potential distractions. . Become familiar with vehicle features before driving, such as programming favourite radio stations and adjusting climate control and seat settings. Program all trip information into any navigation device prior to driving. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 168 Driving and Operating . Wait until the vehicle is parked to . Assume that other road users . Keep pace with traffic. retrieve items that have fallen to the floor. . Stop or park the vehicle to tend to children. . Keep pets in an appropriate carrier or restraint. . Avoid stressful conversations while driving, whether with a passenger or on a mobile phone. (pedestrians, bicyclists, and other drivers) are going to be careless and make mistakes. Anticipate what they may do and be ready. . Allow enough following distance between you and the driver in front of you. . Focus on the task of driving. If the engine ever stops while the vehicle is being driven, brake normally but do not pump the brakes. Doing so could make the pedal harder to push down. If the engine stops, there will be some power brake assist but it will be used when the brake is applied. Once the power assist is used up, it can take longer to stop and the brake pedal will be harder to push. { Warning Taking your eyes off the road too long or too often could cause a crash resulting in injury or death. Focus your attention on driving. Refer to the infotainment section for more information on using that system and the navigation system, if equipped, including pairing and using a mobile phone. Defensive Driving Defensive driving means “always expect the unexpected.” The first step in driving defensively is to wear the seat belt. See Seat Belts 0 45. Control of a Vehicle Braking, steering, and accelerating are important factors in helping to control a vehicle while driving. Braking Braking action involves perception time and reaction time. Deciding to push the brake pedal is perception time. Actually doing it is reaction time. Average driver reaction time is about three-quarters of a second. In that time, a vehicle moving at 100 km/h (60 mph) travels 20 m (66 ft), which could be a lot of distance in an emergency. Helpful braking tips to keep in mind include: . Keep enough distance between you and the vehicle in front of you. . Avoid needless heavy braking. Steering Caution To avoid damage to the steering system, do not drive over kerbs, parking barriers, or similar objects at speeds greater than 3 km/h (1 mph). Use care when driving over other objects such as lane dividers and speed bumps. Damage caused by misuse of the vehicle is not covered by the vehicle warranty. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating Bend Tips 169 Off-Road Recovery . Take bends at a reasonable speed. . Reduce speed before entering a bend. . Maintain a reasonable steady speed through the bend. . Wait until the vehicle is out of the bend before accelerating gently into the straight. Steering in Emergencies . There are some situations when steering Electric Power Steering The vehicle is equipped with an electric power steering system, which reduces the amount of effort needed to steer the vehicle. It does not have power steering fluid. Regular maintenance is not required. If the vehicle experiences a system malfunction and loses power steering, greater steering effort may be required. Power steering assist also may be reduced if you turn the steering wheel as far as it can turn and hold it there with force for an extended period of time. See your dealer if there is a problem. around a problem may be more effective than braking. . Holding both sides of the steering wheel allows you to turn 180 degrees without removing a hand. . The 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 tyre contacts the pavement edge. 3. Turn the steering wheel to go straight down the roadway. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 170 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 bend causes tyres 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 recognise 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 tyres to slide. Remember: Antilock brakes help avoid only the braking skid. Off-Road Driving All-Wheel Drive (AWD) vehicles can be used for off-road driving. Vehicles without AWD and vehicles not equipped with All Terrain (AT) or On-Off Road (OOR) tyres must not be driven off-road except on a level, solid surface. To contact the tyre manufacturer for more information about the original equipment tyres, see the warranty manual. Controlling the vehicle is the key to successful off-road driving. One of the best ways to control the vehicle is to control the speed. { Warning When driving off-road, bouncing and quick changes in direction can easily throw you out of position. This could cause you to lose control and crash. You and your passengers should always wear seat belts. Before Driving Off-Road . Have all necessary maintenance and service work completed. . Fuel the vehicle, fill fluid levels, and check inflation pressure in all tyres, including the spare, if equipped. . Read all the information about AWD vehicles in this manual. . Make sure all underbody shields, if equipped, are properly attached. . Know the local laws that apply to off-road driving. To gain more ground clearance if needed, it may be necessary to remove the front fascia lower air dam. However, driving without the front spoiler reduces fuel economy. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating Caution Operating the vehicle for extended periods without the front fascia lower air dam installed can cause improper airflow to the engine. Reattach the front fascia air dam after off-road driving. Loading the Vehicle for Off-Road Driving { Warning . Unsecured cargo on the load floor can be tossed about when driving over rough terrain. You or your passengers can be struck by flying objects. Secure the cargo properly. . Keep cargo in the cargo area as far forward and as low as possible. The heaviest things should be on the floor, forward of the rear axle. . Heavy loads on the roof raise the vehicle's centre of gravity, making it more likely to roll over. You can be seriously or fatally injured if the vehicle rolls over. Put heavy loads inside the cargo area, not on the roof. For more information about loading the vehicle, see Vehicle Load Limits 0 176. Environmental Concerns . Always use established trails, roads, and areas that have been set aside for public off-road recreational driving and obey all posted regulations. . Do not damage shrubs, flowers, trees, or grasses or disturb wildlife. . Do not park over things that burn. See Parking over Things That Burn 0 185. Driving on Hills Driving safely on hills requires good judgement and an understanding of what the vehicle can and cannot do. { Warning Many hills are simply too steep for any vehicle. Driving up hills can cause the vehicle to stall. Driving down hills can cause loss of control. Driving across hills can cause a rollover. You could be injured or killed. Do not drive on steep hills. Before driving on a hill, assess the steepness, traction, and obstructions. If the terrain ahead cannot be seen, get out of the vehicle and walk the hill before driving further. 171 When driving on hills: . Use a low gear and keep a firm grip on the steering wheel. . Maintain a slow speed. . When possible, drive straight up or down the hill. . Slow down when approaching the top of the hill. { Warning Driving to the top of a hill at high speed can cause a collision. There could be a drop-off, embankment, cliff, or even another vehicle. You could be seriously injured or killed. As you near the top of a hill, slow down and stay alert. . Use headlamps even during the day to make the vehicle more visible. . Never go downhill forward or backward with the transmission in N (Neutral). The brakes could overheat and you could lose control. . When driving down a hill, keep the vehicle headed straight down. Use a low gear because the engine will work with the brakes to slow the vehicle and help keep the vehicle under control. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 172 Driving and Operating { Warning Heavy braking when going down a hill can cause your brakes to overheat and fade. This could cause loss of control and you or others could be injured or killed. Apply the brakes lightly when descending a hill and use a low gear to keep vehicle speed under control. . Avoid turns that take the vehicle across the incline of the hill. Driving across an incline puts more weight on the downhill wheels, which could cause a downhill slide or a roll-over. . Loose gravel, muddy spots, or even wet grass can cause the tyres to slip sideways, downhill. If the vehicle slips sideways, it can hit something and potentially roll over. . Hidden obstacles can make the steepness of the incline more severe. If a rock is driven across with the uphill wheels, or if the downhill wheels drop into a rut or depression, the vehicle can tilt even more. . If an incline must be driven across and the vehicle starts to slide, turn downhill. This should help straighten out the vehicle and prevent side slipping. If the vehicle stalls on a hill: 1. Apply the brakes to stop the vehicle, and then apply the parking brake. 2. Shift into P (Park) and then restart the engine. . If driving uphill when the vehicle stalls, shift to R (Reverse), release the parking brake, and reverse straight down. . Never try to turn the vehicle around. If the hill is steep enough to stall the vehicle, it is steep enough to cause it to roll over. . If you cannot make it up the hill, back straight down the hill. . Never reverse down a hill in N (Neutral) using only the brake. . The vehicle can roll backward quickly and you could lose control. . If driving downhill when the vehicle stalls, shift to a lower gear, release the parking brake, and drive straight down the hill. 3. If the vehicle cannot be restarted after stalling, apply the parking brake, shift into P (Park), and turn the vehicle off. 3.1. Leave the vehicle and seek help. 3.2. Stay clear of the path the vehicle would take if it rolled downhill. { Warning Getting out of the vehicle on the downhill side when stopped across an incline is dangerous. If the vehicle rolls over, you could be crushed or killed. Always get out on the uphill side of the vehicle and stay well clear of the rollover path. Driving in Mud, Sand, Snow, or Ice Use a low gear when driving in mud – the deeper the mud, the lower the gear. Keep the vehicle moving to avoid getting stuck. Traction changes when driving on sand. On loose sand, such as on beaches or sand dunes, the tyres tend to sink into the sand. This affects steering, accelerating, and braking. Drive at a reduced speed and avoid sharp turns or abrupt manoeuvres. Traction is reduced on hard packed snow and ice and it is easy to lose control. Reduce vehicle speed when driving on hard packed snow and ice. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating { Warning Driving on frozen lakes, ponds, or rivers can be dangerous. Ice conditions vary greatly and the vehicle could fall through the ice; you and your passengers could drown. Drive your vehicle on safe surfaces only. Driving in Water { Warning Driving through rushing water can be dangerous. Deep water can sweep your vehicle downstream and you and your passengers could drown. If it is only shallow water, it can still wash away the ground from under your tyres. Traction could be lost, and the vehicle could roll over. Do not drive through rushing water. Caution Do not drive through standing water if it is deep enough to cover the wheel hubs, axles, or exhaust pipe. Deep water can damage the axle and other vehicle parts. If the standing water is not too deep, drive through it slowly. At faster speeds, water can get into the engine and cause it to stall. Stalling can occur if the exhaust pipe is under water. Do not turn off the ignition when driving through water. If the exhaust pipe is under water, the engine will not start. When going through water, the brakes get wet, and it might take longer to stop. See Driving on Wet Roads 0 173. After Off-Road Driving Remove any brush or debris that has collected on the underbody or chassis, or under the bonnet. These accumulations can be a fire hazard. After operation in mud or sand, have the brake linings cleaned and checked. These substances can cause glazing and uneven braking. Check the body structure, steering, suspension, wheels, tyres, and exhaust system for damage and check the fuel lines and cooling system for any leakage. More frequent maintenance service is required. See Maintenance Schedule (Petrol) 0 324 or Maintenance Schedule (Diesel) 0 326. 173 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. { 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. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 174 Driving and Operating Aquaplaning Hill and Mountain Roads Aquaplaning is dangerous. Water can build up under the vehicle's tyres so they actually ride on the water. This can happen if the road is wet enough and you are going fast enough. When the vehicle is aquaplaning, it has little or no contact with the road. Driving on steep hills or through mountains is different than driving on flat or rolling terrain. Tips include: . Keep the vehicle serviced and in good shape. . Check all fluid levels and brakes, tyres, cooling system, and transmission. . Shift to a lower gear when going down steep or long hills. There is no hard and fast rule about aquaplaning. The best advice is to slow down when the road is wet. Other Rainy Weather Tips Besides slowing down, other wet weather driving tips include: . Allow extra following distance. . Overtake with caution. . Keep windscreen wiping equipment in good condition. . Keep the windscreen washer fluid reservoir filled. . Have good tyres with proper tread depth. See Tyres 0 286. . Turn off cruise control. . Activate All-Wheel Drive (AWD) mode. See Driver Mode Control 0 199. { Warning Using the brakes to slow the vehicle on a long downhill slope can cause brake overheating, can reduce brake performance, and could result in a loss of braking. Shift the transmission to a lower gear to let the engine assist the brakes on a steep downhill slope. { Warning Coasting downhill in N (Neutral) or with the ignition off is dangerous. This can cause overheating of the brakes and loss of steering assist. Always have the engine running and the vehicle in gear. . Drive at speeds that keep the vehicle in its own lane. Do not swing wide or cross the centre 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 gradients, overtaking or no-overtaking zones) and take appropriate action. . Select All-Wheel Drive (AWD) Mode. See Driver Mode Control 0 199 and All-Wheel Drive 0 195. Winter Driving Driving on Snow or Ice Caution To avoid damage to the wheels and brake components, always clear snow and ice from inside the wheels and underneath the vehicle before driving. Snow or ice between the tyres 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. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating For Slippery Road Driving: . Accelerate gently. Accelerating too quickly causes the wheels to spin and makes the surface under the tyres slick. . Turn on Traction Control. See Traction Control/Electronic Stability Control 0 198. . The Antilock Brake System (ABS) improves vehicle stability during hard stops, but the brakes should be applied sooner than when on dry surfaces. See Antilock Brake System (ABS) 0 196. . 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 manoeuvres and braking while on ice. . Turn off cruise control. . Select All-Wheel Drive (AWD) Mode for vehicles equipped with AWD. Select Snow/Ice Mode for FWD only vehicles. See Driver Mode Control 0 199 and All-Wheel Drive 0 195. Cold Weather Mode In very low temperatures, a cold weather message may display on the Driver Information Centre (DIC). The engine speed, gearbox shift patterns, and cabin fan speed may operate differently to enable the vehicle to warm up quicker. You can manually override the cabin fan speed in cold weather mode. Blizzard Conditions Stop the vehicle in a safe place and signal for help. Stay with the vehicle unless there is help nearby. To get help and keep everyone in the vehicle safe: . Turn on the hazard warning lights. . 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: (Continued) 175 Warning (Continued) . Clear snow from the base of the vehicle, especially any blocking the exhaust pipe. . Open a window about 5 cm (2 in) on the vehicle side that is away from the wind, to bring in fresh air. . Fully open the air outlets on or under the instrument panel. . Adjust the climate control system to circulate the air inside the vehicle and set the fan speed to the highest setting. See “Climate Control Systems.” For more information about CO, see Engine Exhaust 0 186. To save fuel, run the engine for short periods to warm the vehicle and then shut the engine off and partially close the window. Moving about to keep warm also helps. If it takes time for help to arrive, when running the engine, push the accelerator pedal slightly so the engine runs faster than the idle speed. This keeps the battery Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 176 Driving and Operating charged to restart the vehicle and to signal for help with the headlamps. Do this as little as possible, to save fuel. If the Vehicle Is Stuck Slowly and cautiously spin the wheels to free the vehicle when stuck in sand, mud, ice, or snow. 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 0 198. { Warning If the vehicle's tyres spin at high speed, they can explode, and you or others could be injured. The vehicle can overheat, causing an engine compartment fire or other damage. Spin the wheels as little as possible and avoid going above 56 km/h (35 mph). For All-Wheel Drive (AWD), select Off-Road or AWD mode. See Driver Mode Control 0 199 and All-Wheel Drive 0 195. 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 Transporting a Disabled Vehicle 0 313. Vehicle Load Limits It is very important to know how much weight the vehicle can carry. This weight is called the vehicle capacity weight and includes the weight of all occupants, cargo, and all non-factory-installed options. Two labels on the vehicle may show how much weight it may properly carry, the Tyre and Loading Information label and the Certification/Tyre 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 performance, damage the tyres, and shorten the life of the vehicle. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating Tyre and Loading Information Label pressures (4). For more information on tyres and inflation see Tyres 0 286 and Tyre Pressure 0 288. There is also important loading information on the vehicle Certification/ Tyre 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/Tyre Label” later in this section. Example Label A vehicle-specific Tyre and Loading Information label is attached to the centre pillar (B-pillar). The tyre and loading information label shows the number of occupant seating positions (1), and the maximum vehicle capacity weight (2) in kilograms and pounds. The Tyre and Loading Information label also shows the size of the original equipment tyres (3) and the recommended cold tyre inflation “Steps for Determining Correct Load Limit– 1. Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on your vehicle's placard. 2. Determine the combined weight of the driver and passengers that will be riding in your vehicle. 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, 177 if the “XXX” amount equals 1400 lbs. and there will be five 150 lb passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs. (1400-750 (5 x 150) = 650 lbs.) 5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4. 6. 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 0 246 for important information on towing a trailer, towing safety rules and trailering tips. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 178 Driving and Operating Example 1 Example 2 1. Vehicle Capacity Weight for 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). Example 2 = 453 kg (1,000 lbs). 2. Subtract Occupant Weight @ 68 kg (150 lbs) × 5 = 340 kg (750 lbs). 3. Available Cargo Weight = 113 kg (250 lbs). Example 3 1. Vehicle Capacity Weight for Example 3 = 453 kg (1,000 lbs). 2. Subtract Occupant Weight @ 91 kg (200 lbs) × 5 = 453 kg (1,000 lbs). 3. Available Cargo Weight = 0 kg (0 lbs). Refer to the vehicle's tyre and loading information label for specific information about the vehicle's capacity weight and seating positions. The combined weight of the driver, passengers, and cargo should never exceed the vehicle's capacity weight. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating Certification/Tyre Label The Certification/Tyre label may also show the maximum weights for the front and rear axles, called the Gross Axle Weight Rating (GAWR). To find out the actual loads on the front and rear axles, weigh the vehicle at a weigh station. Your dealer can help with this. Be sure to spread the load equally on both sides of the centreline. Caution Label Example A vehicle-specific Certification/Tyre label is attached to the centre pillar (B-pillar). The label may show the size of the vehicle's original tyres and the inflation pressures needed to obtain the gross weight capacity of the vehicle. The label shows the gross weight capacity of the vehicle. This is called the Gross Vehicle Weight Rating (GVWR). The GVWR includes the weight of the vehicle, all occupants, fuel, and cargo. Overloading the vehicle may cause damage. Repairs would not be covered by the vehicle warranty. Do not overload the vehicle. { Warning 179 Warning (Continued) Never stack heavier things, like suitcases, inside the vehicle so that some of them are above the tops of the seats. . Do not leave an unsecured child restraint in the vehicle. . Secure loose items in the vehicle. . Do not leave a seat folded down unless needed. . Starting and Operating New Vehicle Run-In Caution Things inside the vehicle can strike and injure people in a sudden stop or turn, or in a crash. . 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. (Continued) The vehicle does not need an elaborate run-in. But it will perform better in the long run if you follow these guidelines: . Do not drive at any one constant speed, fast or slow, for the first 800 km (500 mi). Do not make full-throttle starts. Avoid downshifting to brake or slow the vehicle. (Continued) Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 180 Driving and Operating Caution (Continued) . Avoid making hard stops for the first 300 km (200 mi) or so. During this time the new brake linings are not yet broken in. Hard stops with new linings can mean premature wear and earlier replacement. Follow this breaking-in guideline every time you get new brake linings. . Do not tow a trailer during run-in. See Trailer Towing 0 246 for the trailer towing capabilities of the vehicle and more information. Normal driving charges the vehicle's battery to achieve the best operation of the vehicle, including fuel economy and the Stop/Start System. See Stop/Start System 0 183. Stopping the Engine/OFF (No Indicator Light) : When the vehicle is stopped, press ENGINE START/STOP once to turn the engine off. Ignition Positions If the vehicle is in P (Park), the ignition will turn off, and Retained Accessory Power (RAP) will remain active. See Retained Accessory Power (RAP) 0 184. If the vehicle is in R (Reverse), D (Drive) or M (Manual Mode), the vehicle will shift to P (Park), the ignition will turn off, and RAP will remain active. If the vehicle is in N (Neutral), the ignition will return to accessory mode and display the message SHIFT TO PARK in the Driver Information Centre (DIC). Following run-in, engine speed and load can be gradually increased. On new vehicles, the various mechanical and electrical systems experience a “running-in period” period during the first 6 400 km (4,000 mi) of routine driving. As the vehicle is driven, the mechanical systems adjust to provide optimal fuel economy and gear change performance. Electrical systems will adapt and calibrate during the break-in period. A one-time occurrence of clicks and similar vehicle noises is normal during this process. The vehicle has an electronic keyless ignition with pushbutton start. If the pushbutton start is not working, the vehicle may be near a strong radio antenna signal causing interference to the Keyless Access system. See Remote Key Operation 0 7. To shift out of P (Park), the vehicle must be turned on and the brake pedal must be applied. When the vehicle is shifted into P (Park), the ignition will turn off. { Warning Turning off the vehicle while moving may cause loss of power assistance in the brake and steering systems and disable the airbags. While driving, only shut the vehicle off in an emergency. If the vehicle must be shut off in an emergency: Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating 1. Brake using a firm and steady pressure. Do not pump the brakes repeatedly. This may deplete power assist, requiring increased brake pedal force. 2. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving. After shifting to N (Neutral), firmly apply the brakes and steer the vehicle to a safe location. 3. Come to a complete stop and shift to P (Park). 4. Apply the parking brake. See Electric Parking Brake 0 196. Press ENGINE START/STOP to turn the vehicle off. If the vehicle cannot be pulled over and must be shut off while driving, press and hold ENGINE START/STOP for longer than two seconds, or press twice in five seconds. Accessory Mode (Amber Indicator Light) : This mode allows you to use some electrical accessories when the engine is off. With the ignition off, pressing ENGINE START/STOP once without the brake pedal applied will place the ignition system in accessory mode. The ignition will switch from accessory mode to OFF after 10 minutes to prevent battery rundown. ON/RUN/START (Green Indicator Light) : This mode is for driving and starting. With the ignition off and the brake pedal applied, pressing ENGINE START/STOP once will place the ignition system in ON/RUN/START. Once engine cranking begins, release the button. Engine cranking will continue until the engine starts. The ignition will then remain on. See Starting the Engine (Diesel) 0 181 or Starting the Engine (Petrol) 0 182. Service Mode This mode is available to verify the proper operation of the malfunction indicator lamp as may be required for emissions inspection purposes and for service and diagnostics. See Automatic Transmission 0 190. With the vehicle off, and the brake pedal not applied, pressing and holding ENGINE START/STOP for more than five seconds will place the vehicle in Service Mode. The instruments and audio systems will operate as they do in ON/RUN, but the vehicle will not be able to be driven. The engine will not start in Service Mode. Press ENGINE START/ STOP again to turn the vehicle off. 181 Starting the Engine (Diesel) Place the transmission in the proper gear, P (Park) or N (Neutral). To restart the engine when the vehicle is already moving, use N (Neutral) only. Caution Do not try to shift to P (Park) if the vehicle is moving. If you do, you could damage the transmission. Shift to P (Park) only when the vehicle is stopped. Caution If you add electrical parts or accessories, you could change the way the engine operates. Any resulting damage would not be covered by the vehicle warranty. See Add-On Electrical Equipment 0 253. Starting Procedure 1. With the Keyless Access system, the remote key must be in the vehicle. Press ENGINE START/STOP with the brake pedal applied to start. If it is too cold, the wait-to-start light will come on and there will be a short delay before starting. See Wait-to-Start Light 0 103. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 182 Driving and Operating The engine has a fast warm-up glow plug system. The wait-to-start light will illuminate for a much shorter time than most diesel engines, due to the rapid heating of the glow plug system. 2. If the engine does not start after 15 seconds of cranking, wait one minute for the cranking motor to cool, then try the same step again. If the Engine Will Not Start If you are trying to start the engine after you have run out of fuel, follow the steps in Running Out of Fuel (Diesel) 0 239. If the light does not go off, wait a few seconds, then try starting the engine again. See your retailer for a starting system check. When the engine is cold, let it run for a few minutes before driving. This lets oil pressure build up. The engine will sound louder when it is cold. Cold Weather Starting Use the recommended engine oil when the outside temperature drops below freezing. See Engine Oil 0 260. When the outside temperature drops below –18°C (0°F), use of the engine heater is recommended. See Fuel for Diesel Engines 0 234 for information on what fuel to use in cold weather. If you have run out of fuel, see Running Out of Fuel (Diesel) 0 239. If the vehicle is not out of fuel, and the engine will not start: Press ENGINE START/STOP. Immediately after the wait-to-start light turns off, press ENGINE START/STOP to start the vehicle. If the light illuminates and then turns off, and it is known that the battery is charged, but the engine still will not start, the vehicle needs service. If the light does not come on when the engine is cold, the vehicle needs service. Make sure you use the proper fuel for the prevailing weather conditions. See Fuel for Diesel Engines 0 234. If the engine starts, runs a short time, then stops, the vehicle needs service. { Warning Do not use petrol or starting aids, such as ether, in the air intake. They could damage the engine, which may not be covered by the vehicle warranty. They could also cause a fire, which could cause serious personal injury. Starting the Engine (Petrol) Place the transmission in the proper gear, P (Park) or N (Neutral). To restart the engine when the vehicle is already moving, use N (Neutral). If the battery does not have enough charge to start the engine, see Battery 0 271. Caution Check that the correct engine oil has been used and changed at appropriate intervals. If the wrong oil is used, the engine may be harder to start. Do not try to shift to P (Park) if the vehicle is moving. If you do, you could damage the transmission. Shift to P (Park) only when the vehicle is stopped. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating Caution Caution (Continued) If you add electrical parts or accessories, you could change the way the engine operates. Any resulting damage would not be covered by the vehicle warranty. See Add-On Electrical Equipment 0 253. To start the vehicle: 1. With the Keyless Access system, the remote key must be in the vehicle. Press ENGINE START/STOP with the brake pedal applied. When the engine begins cranking, let go of the button. The idle speed will go down as the engine warms up. Do not race the engine immediately after starting it. If the remote key is not in the vehicle, if there is interference, or if the remote key battery is low, a Driver Information Centre (DIC) message will display. See Remote Key Operation 0 7. Caution Cranking the engine for long periods of time, by pressing ENGINE START/STOP immediately after cranking has ended, can overheat and damage the cranking (Continued) motor, and drain the battery. Wait at least 15 seconds between each try, to let the cranking motor cool down. 2. If the engine does not start after five to 10 seconds, especially in very cold weather (below −18 °C or 0 °F), it could be flooded with too much petrol. Try pushing the accelerator pedal all the way to the floor and hold it there, then press ENGINE START/STOP for up to a maximum of 15 seconds. Wait at least 15 seconds between each try, to allow the cranking motor to cool down. When the engine starts, let go of the button and the accelerator. If the vehicle starts briefly but then stops again, do the same thing. This clears the extra petrol from the engine. Do not race the engine immediately after starting it. Operate the engine and transmission gently until the oil warms up and lubricates all moving parts. 183 Stop/Start System The Stop/Start system will shut off the engine to help conserve fuel. It has components designed for the increased number of starts. { Warning The automatic engine Stop/Start feature causes the engine to shut off while the vehicle is still on. Do not exit the vehicle before shifting to P (Park). The vehicle may restart and move unexpectedly. Always shift to P (Park), and then turn the ignition off before exiting the vehicle. Auto Engine Stop/Start When the brakes are applied and the vehicle is at a complete stop, the engine may turn off. When stopped, the tachometer displays AUTO STOP. See Rev Counter 0 93. When the brake pedal is released or the accelerator pedal is depressed, the engine will restart. To maintain vehicle performance, other conditions may cause the engine to automatically restart before the brake pedal is released. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 184 Driving and Operating Auto Stops may not occur and/or Auto Starts may occur because: .

You may not be able to release the EPB using the EPB switch. It should automatically release when the vehicle is shifted out of P (Park). Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating Leaving the Vehicle with the Engine Running { Warning It can be dangerous to leave the vehicle with the engine running. It could overheat and catch fire. It is dangerous to get out of the vehicle if the vehicle is not in P (Park) with the Electric Parking Brake (EPB) applied. The vehicle can roll. Do not leave the vehicle when the engine is running. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move, even when you are on fairly level ground, always apply the EPB and shift the vehicle to P (Park). If you are towing a trailer, see Driving Characteristics and Towing Tips 0 243. If you have to leave the vehicle with the engine running, be sure the vehicle is in P (Park) and the EPB is set before you leave it. See Electric Parking Brake 0 196. If you are towing a trailer and parking on a hill, see Driving Characteristics and Towing Tips 0 243. Shifting out of Park This vehicle is equipped with an electronic transmission. The shift lock release button is designed to prevent inadvertent shifting out of P (Park). To 1. 2. 3. shift out of P (Park): Ensure the engine is running. Apply the brake pedal. Press and hold the shift lock release button. 4. Move the shift lever to the desired position. 5. The P indicator will turn white and the gear indicator on the gear lever will turn red when the vehicle is no longer in P (Park). 6. After releasing the gear lever, it will return to the centre position. If the vehicle cannot shift from P (Park), a Driver Information Centre (DIC) message may be displayed. Check that the ignition is switched on, the engine is running, the brake pedal is depressed, and the shift lock 185 release button is pressed when you are attempting to shift out of P (Park). If all of these conditions are met but the vehicle will not shift out of P (Park), see your retailer for service. Parking over Things That Burn { Warning Things that can burn could touch hot exhaust parts under the vehicle and ignite. Do not park over papers, leaves, dry grass, or other things that can burn. Active Fuel Management This vehicle's engine may be equipped with Active Fuel Management, which allows the engine to operate on either all of its cylinders, or in reduced cylinder operation mode, depending on the driving conditions. When less power is required, such as cruising at a constant vehicle speed, the system will operate in reduced cylinder operation mode, allowing the vehicle to achieve better fuel economy. When greater power demands are required, such as accelerating from a stop, overtaking, or merging onto a freeway, the system will maintain full-cylinder operation. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 186 Driving and Operating If the vehicle has an Active Fuel Management indicator, see Driver Information Centre (DIC) for more information about using this display. Extended Parking It is best not to park with the vehicle running. If the vehicle is left running, be sure it will not move and there is adequate ventilation. See Shifting Into Park 0 184 and Engine Exhaust 0 186. If the vehicle is left parked and running with the remote key outside the vehicle, it will continue to run for up to 15 minutes. If the vehicle is left parked and running with the remote key inside the vehicle, it will continue to run for up to 30 minutes. The vehicle could turn off sooner if it is parked on a hill, due to lack of available fuel. The timer will reset if the vehicle is taken out of P (Park) while it is running. Engine Exhaust { Warning Engine exhaust contains carbon monoxide (CO), which cannot be seen or smelled. Exposure to CO can cause unconsciousness and even death. Exhaust may enter the vehicle if: . The vehicle idles in areas with poor . . . . ventilation (parking garages, tunnels, deep snow that may block underbody airflow or exhaust pipes). The exhaust smells or sounds strange or different. The exhaust system leaks due to corrosion or damage. The vehicle exhaust system has been modified, damaged, or improperly repaired. There are holes or openings in the vehicle body from damage or aftermarket modifications that are not completely sealed. (Continued) Warning (Continued) If unusual fumes are detected or if it is suspected that exhaust is coming into the vehicle: . Drive it only with the windows completely down. . Have the vehicle repaired immediately. Never park the vehicle with the engine running in an enclosed area such as a garage or a building that has no fresh air ventilation. Running the Vehicle While Parked It is better not to park with the engine running. If the vehicle is left with the engine running, follow the proper steps to be sure the vehicle will not move. See Shifting Into Park 0 184 and Engine Exhaust 0 186. Diesel Particulate Filter The exhaust system has a Diesel Particulate Filter (DPF) to reduce vehicle emissions. On some exhaust systems with a DPF, the Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating exhaust cooler mixes air with the exhaust to lower the temperature before it leaves the tailpipe. The DPF, the tailpipe, and other exhaust system components must not be altered. Regularly inspect and clean any mud or dirt from the exhaust cooler, especially where the exhaust cooler connects to the tailpipe and the openings where fresh air enters the cooler. The DPF will clean itself as part of normal operation. Several factors, including fuel consumed, hours of engine operation, and miles driven, are monitored by the Engine Control Module (ECM). The self-cleaning occurs approximately once per tank of fuel. Vehicles with the DPF have specific fuel and engine oil requirements. See Fuel for Diesel Engines 0 234 and Engine Oil 0 260. Caution Damage can occur to the DPF components if the required Ultra Low Sulphur Diesel (15 ppm sulphur maximum) fuel and engine oil specified in the Recommended Fluids and Lubricants (Continued) 187 Caution (Continued) Caution section of this manual are not used. This damage would not be covered by the vehicle warranty. Avoid extended idling because the DPF system is not capable of self-cleaning at idle speed. During extended idling, monitor the instrument cluster lights and DIC for messages and take appropriate action. Continued idling with the warning light/message shown could cause damage to the DPF, requiring repair and possible replacement that might not be covered by the vehicle warranty. Under certain conditions, such as idling or very short trips, the self-cleaning process has less efficiency and cannot be completed. To resolve this, continue driving safely at a steady speed as close to the posted speed limit as possible, preferably without stopping, until the message clears. This can take up to 30 minutes. { Warning During DPF self cleaning or during extended idling in P (Park), the exhaust system and exhaust gases are very hot. Things that burn could touch hot exhaust parts under the vehicle and ignite. You or others could be burned. Do not park, or idle for an extended period of time, near or over papers, leaves, dry grass, or other things that can burn. Keep the exhaust area clear of material that could ignite or burn. See “Parking over Things That Burn” in the owner's manual. During self-cleaning, there will be a change in the exhaust sound and engine idle speed. Along with this, a burning smell and reduction in fuel economy may be noticed. This is normal. If the vehicle is run at idle speed or driven on very short trips with the DPF warning message shown and the exhaust filter is not cleaned as required, the malfunction indicator lamp and a DIC message will be shown. See your dealer. Also see Malfunction Indicator Lamp (Check Engine Light) 0 97. See Accessories and Modifications 0 255 if you are adding accessories or modifying the vehicle. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 188 Driving and Operating AdBlue { Warning Avoid getting AdBlue (also referred to as Diesel Exhaust Fluid or DEF) on your skin or in your eyes as it could cause irritation. For more safety, handling, and storage information, see the AdBlue container label. Caution Use only AdBlue that is GM approved, or fluid containing the API certified or ISO 22241 label. The use of other fluids could damage the system, requiring costly repairs that will not be covered by the vehicle warranty. Caution Do not mix fuel with AdBlue, and do not fill AdBlue into the fuel tank. This could lead to costly repairs that might not be covered by the vehicle warranty. AdBlue is used with diesel engines to reduce the amount of regulated emissions produced. The fluid level in the AdBlue tank must be maintained for the vehicle to run properly. AdBlue is not a fuel additive. AdBlue freezes when exposed to temperatures below −11 °C (12 °F). For AdBlue tank capacity, see Capacities and Specifications 0 335. Filling the AdBlue Tank It is normal to hear the AdBlue system purge fluid back into the tank after the vehicle is shut off. Locating AdBlue AdBlue can be purchased at your authorised retailers. Additionally, some diesel truck filling stations or retailers may have AdBlue available for purchase. See Recommended Fluids and Lubricants 0 330. The blue AdBlue cap is behind the fuel/ AdBlue hatch. If equipped with a fuel cap, do not remove the fuel and AdBlue caps at the same time. Fill diesel fuel and AdBlue independently. Turn the AdBlue cap anticlockwise to remove. In cold conditions, AdBlue can freeze in the AdBlue filler pipe opening. If this prevents the filling of the AdBlue tank, park the vehicle in a warm garage overnight. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating 189 If AdBlue is added under freezing conditions, it may require less fluid to fill the AdBlue tank. When fluid reaches the top of the AdBlue filler pipe, stop filling. Do not top up the AdBlue tank. If using a bottle or jug to refill AdBlue, follow the instructions on the container label and use a dedicated filling aid. Caution Do not overfill the AdBlue tank and do not allow AdBlue to make contact with the finished surfaces of the vehicle, as it could damage the vehicle finish. If AdBlue is spilled during filling, wipe any affected surface with a damp cloth. When replacing the AdBlue cap, turn it clockwise until it clicks. Make sure the cap is fully installed. Push the fuel/AdBlue hatch closed. AdBlue Low Fill the AdBlue tank on level ground and with the vehicle switched off. When adding AdBlue, it is recommended to fully fill the AdBlue tank. For AdBlue tank capacity, see Capacities and Specifications 0 335. When adding AdBlue to an empty tank or tank approaching empty, always fully fill the AdBlue tank and allow the vehicle to restart. As the AdBlue level drops, warnings automatically display in the Driver Information Centre (DIC). Select Vehicle Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 190 Driving and Operating Information in the DIC to view AdBlue level status. See Driver Information Centre (DIC) 0 106. Refill the AdBlue tank at the first opportunity after a low warning indication. If the AdBlue tank is empty, the vehicle may not restart. It may take some time for the vehicle to detect that AdBlue has been added. If AdBlue is added in freezing conditions, additional time may be required to recognise the new AdBlue level. The AdBlue range DIC message first displays at approximately 2400 km (1,491 mi). This message appears again at approximately 1750 km (1,087 mi) of remaining range before the AdBlue tank becomes empty. As the fluid level nears empty, these messages appear every time the vehicle is started. If the AdBlue low warnings are ignored and the AdBlue tank becomes empty, the DIC will display messages that describe the action needed and distance until vehicle restarts are prevented. AdBlue Quality Poor Automatic Transmission Use only AdBlue that is GM approved, or fluid containing the API certified or ISO 22241 label. AdBlue has an expiration date. If the system detects poor quality, or contaminated, or diluted AdBlue, a DIC message will display along with distance until vehicle restarts are prevented. There will also be a flashing warning light and chimes. Adding fresh AdBlue to the system may resolve the problem after driving a short distance, depending on several factors. If the DIC message persists, see your dealer. High Emission Warnings If a problem occurs with the vehicle emission system, chimes sound and a DIC message displays along with distance until vehicle restarts will be prevented. In some cases, this message will clear itself, indicating that the emission system has corrected the condition. If the DIC message persists, see your dealer. The shift pattern is displayed in the top of the gear lever. The selected gear position will illuminate red on the gear lever, while all others will be displayed in white. If the gear change is not immediate, as in very cold conditions, the indicator on the gear lever may flash until it is fully engaged. The gear lever always starts from a centre position, represented by an up/down arrow on the shift pattern. After releasing the gear lever, it will return to the centre position. The transmission does not operate when the vehicle is off. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating If the vehicle is in accessory mode, the gearbox can be shifted into P (Park). { Warning If the vehicle is turned off while at a relatively high vehicle speed, the transmission will automatically shift to N (Neutral). Once the vehicle is stopped, P (Park) is automatically selected. It is dangerous to get out of the vehicle if the transmission is not in P (Park) with the parking brake applied. The vehicle can roll. P : This position locks the drive wheels. Use P (Park) when starting the engine to prevent the vehicle from moving. Do not leave the vehicle when the engine is running.

In FWD Mode engine power is transferred to the front wheels only, and the AWD feature is off. While using Tap Shift, the vehicle will have firmer, quicker shifting. 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 AWD feature is automatically activated when certain modes are selected using the Driver Mode Control switch. When an AWD mode change is requested the light will flash briefly while the system is engaging and the AWD light will be displayed when the system is active. When a non-AWD Mode is selected, the light will flash briefly while the system disengages and a 2WD light will be displayed when the AWD system is off. See Driver Mode Control 0 199. 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, the M or D will flash 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 All-Wheel Drive Vehicles with this feature can operate in All-Wheel Drive (AWD) Mode. When the AWD feature is active, the system transfers engine power, if required, to all four wheels. The system is fully automatic and adjusts to When a compact spare tyre is installed on an AWD vehicle, the system will automatically detect the compact spare and reduce AWD performance to protect the system. To restore AWD operation and prevent excessive wear on the system, replace the compact spare with a full-size tyre as soon as possible. See Compact Spare Tyre 0 310. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 196 Driving and Operating Brakes Electric Brake Boost Vehicles equipped with electric brake boost have hydraulic brake circuits that are electronically controlled when the brake pedal is applied during normal operation. The system performs routine tests and turns off within a few minutes after the vehicle is turned off. Noise may be heard during this time. If the brake pedal is depressed during the tests or when the electric brake boost system is off, a noticeable change in pedal force and travel may be felt. This is normal. Antilock Brake System (ABS) The Antilock Brake System (ABS) helps prevent a braking skid and maintain steering while braking hard. If there is a problem with ABS, this warning light stays on. See Antilock Brake System (ABS) Warning Light 0 100. ABS does not change the time needed to put your foot on the brake pedal and does not always decrease stopping distance. If you get too close to the vehicle ahead, there will not be enough time to apply the brakes if it suddenly slows or stops. Always leave enough room ahead to stop, even with ABS. Electric Parking Brake Using ABS Do not pump the brakes. Just hold the brake pedal down firmly. Hearing and feeling ABS operate is normal. Braking in Emergencies ABS allows steering and braking at the same time. In many emergencies, steering can help even more than braking. The Electric Parking Brake (EPB) can always be applied, even if the vehicle is switched off. In case of insufficient electrical power, the EPB cannot be applied or released. To prevent draining the battery, avoid unnecessary repeated cycles of the EPB. The system has a red parking brake status light, and an amber parking brake service warning light. See Electric Parking Brake Light 0 99 and Service Electric Parking Brake Light 0 99. There are also handbrake-related Driver Information Centre (DIC) messages. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating Before leaving the vehicle, check the red handbrake status light to ensure that the handbrake 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 red handbrake status light will flash and then stay on once the EPB is fully applied. If the red handbrake status light flashes continuously, then the EPB is only partially applied or there is a problem with the EPB. A DIC message will display. Release the EPB and try to apply it again. If the light does not come on, or keeps flashing, have the vehicle serviced. Do not drive the vehicle if the red handbrake status light is flashing. See your dealer. If the amber parking brake service warning light is illuminated, press the EPB switch. Continue to hold the switch until the red handbrake status light remains on. If the amber parking brake service warning light is illuminated, see your retailer. 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 takes place to periodically check the correct operation of the EPB system, or at the request of other safety functions that utilise the EPB. If the EPB fails to apply, block the rear wheels to prevent vehicle movement. EPB Release To release the EPB: 1. Turn the ignition on or to accessory mode. 2. Apply and hold the brake pedal. 3. Press the EPB switch momentarily. The EPB is released when the red handbrake status light is off. If the amber parking brake service warning light is illuminated, release the EPB by pressing and holding the EPB switch. Continue to hold the switch until the red 197 handbrake status light is off. If either light stays on after release is attempted, see your dealer. Caution Driving with the parking brake on can overheat the brake system and cause premature wear or damage to brake system parts. Make sure that the parking brake is fully released and the brake warning light is off before driving. If you are towing a trailer and parking on a hill, see Driving Characteristics and Towing Tips 0 243. Automatic EPB Release The EPB will automatically release if the vehicle is running, placed into gear and an attempt is made to drive away. Avoid rapid acceleration when the EPB is applied, to preserve parking brake lining life. Brake Assist Brake Assist detects rapid brake pedal applications due to emergency braking situations and provides additional braking to activate the Antilock Brake System (ABS) if the brake pedal is not pushed hard enough Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 198 Driving and Operating to activate ABS normally. Minor noise, brake pedal pulsation, and/or pedal movement during this time may occur. Continue to apply the brake pedal as the driving situation dictates. Brake Assist disengages when the brake pedal is released. Hill Start Assist (HSA) { Warning Do not rely on the HSA feature. HSA does not replace the need to pay attention and drive safely. You may not hear or feel alerts or warnings provided by this system. Failure to use proper care when driving may result in injury, death, or vehicle damage. See Defensive Driving 0 168. When the vehicle is stopped on a grade, Hill Start Assist (HSA) prevents the vehicle from rolling in an unintended direction during the transition from brake pedal release to accelerator pedal apply. The brakes release when the accelerator pedal is applied. If the accelerator pedal is not applied within a few minutes, the Electric Parking Brake will apply. The brakes may also release under other conditions. Do not rely on HSA to hold the vehicle. HSA is available when the vehicle is facing uphill in a forward gear, or when facing downhill in R (Reverse). The vehicle must come to a complete stop on a grade for HSA to activate. Ride Control Systems Traction Control/Electronic Stability Control System Operation The vehicle has a Traction Control System (TCS) and StabiliTrak/Electronic Stability Control (ESC). 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. On an All-Wheel Drive (AWD) vehicle in AWD or Sport Mode, the system will operate if it senses that any of the 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 system senses a discrepancy between the intended path and the direction the vehicle is actually travelling. StabiliTrak/ESC selectively applies braking pressure at any one of the vehicle's brakes to help steer the vehicle in the direction in which you are steering. 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. TCS and StabiliTrak/ ESC will automatically turn on when cruise control is set. 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.

Adaptive Cruise Control (Advanced) If equipped with Adaptive Cruise Control (ACC), it allows the driver to select the cruise control set speed and following gap. Read this entire section before using this system. The following gap is the following time 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. ACC uses camera and radar sensors. If a vehicle is detected in your path, ACC can apply acceleration or limited, moderate braking to maintain the selected following gap. To disengage ACC, apply the brake. If ACC is controlling your vehicle speed when the Traction Control System (TCS) or StabiliTrak/Electronic Stability Control (ESC) system activates, the ACC may automatically disengage. See Traction Control/Electronic Stability Control 0 198. When road conditions allow ACC to be safely used, the ACC can be turned back on. Disabling the TCS or StabiliTrak/ESC system will disengage and prevent engagement of ACC. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating ACC can reduce the need for you to frequently brake and accelerate, especially when used on expressways, dual carriageways and motorways. When used on other roads, you may need to take over the control of braking or acceleration more often. ACC automatically slows the vehicle while navigating a bend and may increase speed out of the bend, but will not exceed the set speed. { 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 0 168. 205 { 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 set speed can also be decreased while the vehicle is stopped. . If stopped with the brake applied, press or hold SET− until the desired set speed is displayed. Selecting the Follow Distance Gap When a slower moving vehicle is detected ahead within the selected following gap, ACC will adjust the vehicle's speed and attempt to maintain the follow distance gap selected. Press [ on the steering wheel to adjust the following gap. Each press cycles the gap button through three settings: Far, Medium, or Near. When pressed, the current gap setting displays briefly on the instrument cluster and HUD, if equipped. The gap setting will be maintained until it is changed. Since each gap setting corresponds to a following time (Far, Medium, or Near), the following distance will vary based on vehicle speed. 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 0 222. Alerting the Driver Without Head-Up Display 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 will flash on the windscreen. Either eight beeps will sound from the front, or both sides of the Safety Alert Seat will pulse five times. Touch the Settings icon on the infotainment home page. Select “Vehicle” to display the list of available options and select “Collision/Detection Systems”. See Defensive Driving 0 168.

The vehicle ahead indicator is in the instrument cluster and HUD display, if equipped. The vehicle ahead indicator only displays when a vehicle is detected in your vehicle's path moving in the same direction. If this symbol 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. { Warning When using ACC to overtake a vehicle or change lane, the distance to the vehicle ahead being overtaken may be reduced. ACC may not apply sufficient acceleration or braking when overtaking a vehicle or changing lane. Always be ready to accelerate or brake manually to finish overtaking or changing lane. Stationary or Very Slow-Moving Objects { Warning 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 when a vehicle suddenly appears due to a vehicle ahead changing lanes. Your vehicle may (Continued) 209 Warning (Continued) not stop and could cause a crash. Use caution when using ACC.

Under certain conditions, the Park Assist system can assist the driver during reversing and parking manoeuvres when the vehicle is driven at no more than 9 km/h (6 mph). An illuminated indicator in the Park Assist button indicates the system is ready. Sensors located in the bumpers measure the distance between the vehicle and objects using sonar technology. These sensors are designed to detect certain objects up to 1.5 m (5 ft) behind and 1.2 m (4 ft) in front of your vehicle that are taller than 25 cm (10 in). Different environmental conditions may affect whether and how far away the Park Assist system can detect objects. Keep the Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating sensors clean of mud, dirt, snow, ice, and slush; and clean sensors after a car wash in freezing temperatures. Sensors that are not clean may not detect objects or may cause the system to alert when not required. { Warning The Park Assist System is no substitute for careful and attentive driving. The Park Assist system does not detect children, pedestrians, cyclists, 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 9 km/h (6 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 reversing. How the System Works The vehicle may have a Park Assist amphitheatre-like display on the cluster with bars that represent the estimated location of a detected object and the vehicle's distance from the object. As a detected object gets closer, more bars light up and change colour from yellow to amber to red. When an object is first detected in the rear, one beep will be heard from the rear, or the driver's seat will pulse two times, if equipped with Safety Alert Seat. When an object is very close, five beeps will sound from the front or rear (depending on the object's location), or the driver's seat will pulse five times. Beeps for front are higher pitched than the rear. 217 The X button is used to turn on or off the Park Assist, which also turns the Reversing Warning and Reverse Automatic Braking (RAB) on or off at the same time. When the system is turned off, a system off message is shown on the display. This message disappears after a short period of time. Turn off Park Assist when towing a trailer and when a bike rack is attached to prevent unwanted beeps and to ensure proper operation. When the System Does Not Seem to Work Properly Turning the System On and Off The Park Assist System can be turned on or off using the infotainment system. To view available settings for this feature, touch the Settings icon on the infotainment home page. Select “Vehicle” to display the list of available options and select “Collision/ Detection Systems”. If a service message displays, check the following conditions: . The sensors may not be clean. Keep the vehicle's front and rear bumpers free of mud, dirt, snow, ice and slush. For cleaning instructions, see Exterior Care 0 315. . The Park Assist sensors may be covered by frost or ice. Frost or ice can form around and behind the sensors and may not always be seen; this can occur after washing the vehicle in cold weather. The message may not clear until the frost or ice has melted. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 218 Driving and Operating If a service message displays and the above conditions do not exist, take the vehicle to your dealer for repairs. If the Park Assist System does not activate due to a temporary condition, a system off message is shown on the display. This can occur under the following conditions: . The driver has disabled the system. . An object is currently blocking the rear sensors (for example, bike rack, tailgate, trailer hitch, etc.). Once the object is removed, Park Assist will return to normal operation. . The bumper is damaged. Take the vehicle to your dealer for repairs. . Other conditions, such as vibrations from a jackhammer or the compression of air brakes on a very large truck, are affecting system performance. Automatic Parking Assist (APA) Automatic Parking Assist (APA) with Braking If equipped, under certain conditions APA with Braking can use sensors based on sonar technology along the vehicle's front, rear and sides to detect a parking spot, and then automatically park the vehicle with some driver assistance. The vehicle will automatically manoeuvre into a detected spot moving at or near idle speed. It does this by automatically steering and braking while the driver is responsible for acceleration and changing gear as needed. The driver must always be prepared to apply braking or additional acceleration, as needed. A display and audible beeps help to guide the parking manoeuvres. { Warning APA may not always detect objects in the parking space, objects that are not rigid (e.g. shrubs and chain-link fences), objects below the bumper, objects high off the ground (e.g. flatbed trucks), hanging objects, objects below ground level (e.g. large potholes), or moving objects (e.g. pedestrians, cyclists, vehicles). Always verify that the parking space is appropriate for parking a vehicle. APA may not respond to changes in the parking space, such as the movement of an adjacent vehicle, or a person or object entering the parking space. APA does not detect or avoid traffic that is behind or (Continued) Warning (Continued) alongside the vehicle. Always be prepared to stop the vehicle during the parking manoeuvre. How to Activate Automatic Parking To activate APA, press the soft-touch button or hard switch O for the system to begin searching for a parking space while driving forward at no greater speed than 30 km/h (18 mph). By default, APA searches for parallel parking spaces to the right of the vehicle up to the sensors' range of 1.5 m (5 ft). To search for a parking space to the left, turn on the left indicator or, if available, change the side selection in the infotainment display. To switch the parking mode between parallel and perpendicular press and hold O while searching for a valid parking spot or, if available, change the parking mode in the infotainment display. APA cannot park in all empty parking spots. The parking spot must: . Be sufficiently large to fit the vehicle comfortably. . Have an adjacent vehicle, wall, or pillar for the system to align to. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating 219 and change gears as needed. Be prepared to stop to avoid vehicles, pedestrians, or objects. After completely passing an eligible parking spot, a beep sounds and a red stop symbol is displayed in the driver information centre. Generally, APA selects the nearest empty parking spot behind the vehicle, but under some conditions may select a space that is further back. Slow down and bring the vehicle to a complete stop to begin. Follow the displayed instructions. When instructed to drive in reverse, change to R (Reverse) while holding the brakes. The steering wheel will vibrate briefly as a reminder to remove hands from the steering wheel. After the vibration stops, check your surroundings and release the brakes to begin automatic parking. As the vehicle automatically steers, and brakes into the parking spot, check the surroundings and continue to apply acceleration if necessary A progress arrow displays the status of the parking manoeuvre. Once automatic parking is finished and the vehicle has come to a full stop, APA will beep and display a message indicating parking is complete. Move the gear lever to P (Park) and apply the parking brake Automatic Unparking How to Cancel Automatic Parking Automatic Parking To cancel automatic parking or automatic unparking at any time, press O. Be prepared to resume full control of the vehicle. APA holds the vehicle until the parking brake or brake is applied, or the gear lever is moved to P (Park). To start driving away, press the brakes and change to D (Drive). Certain vehicle conditions and driver interference may also cancel automatic parking: . The driver manually steers the vehicle. . The maximum allowed speed is exceeded. . There is a failure with the APA system. . Electronic stability control or antilock brakes are activated. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 220 Driving and Operating . The parking brake is applied. . Driver unbuckles the seat belt and opens the door. System Limitations Automatic Parking Assist has certain limitations. The system cannot: . Continue to operate if the manoeuvre speed exceeds 5 km/h (3 mph). . Detect whether a parking space is legal or restricted. . Detect pavement markings or lines. . Park the vehicle closely lined up with the vehicle next to it, particularly if the spot is approached at an angle or if the parking space is angled. . Park exactly centred in a very large spot. . Always detect short curbs. . Operate while towing any trailer. . Function the vehicle is raised or lowered by air suspension,if equipped. When the System Does Not Seem to Work Properly If the vehicle does not reverse into the expected parking space, the system could be manoeuvring the vehicle into a previously detected space. Reverse Automatic Braking (RAB) Reversing Warning and Reverse Automatic Braking (RAB) If equipped, vehicles with Adaptive Cruise Control (ACC) have the Reverse Warning System and Reverse Automatic Braking (RAB) system. When in R (Reverse), Reversing Warning alerts of rear objects at vehicle speeds greater than 8 km/h (5 mph), and RAB may automatically brake hard at speeds between 1–32 km/h (0.5–20 mph). The Reversing 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 Reversing Warning System only operates at speeds greater than 8 km/h (5 mph). It does not detect children, pedestrians, bicyclists, animals, or objects (Continued) Warning (Continued) below the bumper or that are too close or too far from the vehicle. In some situations, such as at higher reversing 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 Reversing Warning System, always check the area around the vehicle and check all mirrors before reversing. When the vehicle is in R (Reverse), if the system detects the vehicle is reversing 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 reversing crash. { Warning RAB may not avoid many types of reversing 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 (Continued) Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating Warning (Continued) Warning (Continued) vehicle.

Assistance Systems for Driving If equipped, when driving the vehicle in a forward gear, Forward Collision Alert (FCA), Lane Keep Assist (LKA), Side Blind Zone Alert (SBZA), Lane Change Alert (LCA), Automatic Emergency Braking (AEB), and/or the Front Pedestrian Braking (FPB) System can help to avoid a collision or reduce collision damage. Forward Collision Alert (FCA) System If equipped, the FCA system may help to avoid or reduce the harm caused by front-end crashes. When approaching a vehicle ahead too quickly, FCA provides a red flashing alert on the windscreen 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 (Advanced) 0 204. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating { Warning FCA is a warning system and does not apply the brakes. When approaching a slower-moving or stopped vehicle ahead too rapidly, or when following a vehicle too closely, FCA may not provide a warning with enough time to help avoid a crash. It also may not provide any warning at all. FCA does not warn of pedestrians, animals, signs, crash barriers, bridges, construction barrels, or other objects.

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 windscreen in front of the rearview mirror. . Clean the entire front of the vehicle. . Clean the headlights. Automatic Emergency Braking (AEB) If equipped, the AEB system may help avoid or reduce the harm caused by front-end crashes. AEB also includes Intelligent Brake Assist (IBA). When the system detects a vehicle in the path ahead that is travelling in the same direction, it can provide a boost to braking, or automatically brake the vehicle, to avoid a collision. This can help avoid or lessen the severity of crashes when driving in a forward gear. Depending on the situation, the vehicle may automatically Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating brake moderately or hard. This Automatic Emergency Braking can only engage if a vehicle is detected. When detecting a vehicle, the Forward Collision Alert (FCA) vehicle ahead indicator light will be illuminated. See Forward Collision Alert (FCA) System 0 222. 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). { Warning AEB is an emergency crash preparation feature and is not designed to avoid collisions. Do not rely on AEB to brake the vehicle. AEB will not brake outside of its operating speed range and only responds to detected vehicles. AEB may not: . Detect a vehicle ahead on winding or hilly roads. . Detect all vehicles, especially vehicles with a trailer, tractors, muddy vehicles, etc. (Continued) Warning (Continued) . 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. AEB may slow the vehicle to a complete stop to try to avoid a potential collision. If this happens, AEB may engage the Electric Parking Brake (EPB) to hold the vehicle at a stop. Release the EPB or firmly press the accelerator pedal. { Warning AEB may automatically brake the vehicle suddenly in situations where it is unexpected and undesired. It could respond to a turning vehicle ahead, guardrails, signs, and other non-moving objects. To override AEB, firmly depress the accelerator pedal, if it is safe to do so. 225 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. AEB and IBA can be disabled through vehicle settings.

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 or cyclist 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 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 or cyclists, including 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 personalisation.

Turn the system to Alert or Off when towing a trailer. Cleaning the System If FPB does not seem to operate properly, cleaning the outside of the windscreen in front of the rear-view mirror may correct the issue. Side Blind Zone Alert (SBZA) If equipped, the SBZA system is a lane-changing aid that assists drivers to avoid a collision with vehicles moving in the side blind zone, or blind spot areas. When the vehicle is in a forward gear, the left or right side mirror display will light up if a moving vehicle is detected in that blind zone. If the indicator is activated and a vehicle is also detected on the same side, the display will flash as an extra warning not to change lanes. Since this system is part of the Lane Change Alert (LCA) system, read the entire LCA section before using this feature. LCA Detection Zones Lane Change Alert (LCA) If equipped, the LCA system is a lane-changing aid that assists drivers with avoiding lane change crashes that occur with moving vehicles in the side blind zone (or spot) areas or with vehicles rapidly approaching these areas from behind. The LCA warning display will light up in the corresponding outside side mirror and will flash if the indicator 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 indicators. 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 side mirrors when the system detects a moving vehicle in the next lane over that is in the side Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating 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 indicators. Left Side Mirror Display Right Side Mirror Display from the infotainment screen, touch Settings > Vehicle > Collision/Detection Systems. 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 motorway with traffic and roadside objects (e.g., guardrails, barriers). When the vehicle is started, both outside mirror LCA displays will briefly come on to indicate the system is operating. When the vehicle is in a forward gear, the left or right side mirror display will light up if a moving vehicle is detected in the next lane over in that blind zone or rapidly approaching that zone. If the indicator is activated in the same direction as a detected vehicle, this display will flash as an extra warning not to change lanes. 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 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 can be disabled through vehicle personalisation. When you disable LCA, SBZA is also disabled. To view available settings LCA may not always alert the driver to vehicles in the next lane over, especially in wet conditions or when driving on sharp 229 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 0 315. 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 illuminate 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. Traffic Sign Assistant If equipped, traffic sign assistant recognises designated traffic signs via the front camera located behind the windscreen in front of the interior rear view mirror, and displays the detected speed limit in the Driver Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 230 Driving and Operating Information Centre (DIC). Additionally, speed limit information from the navigation system map database may be used. Caution The system is intended to assist the driver within a defined speed range to discern certain traffic signs. Always pay attention to posted speed limit signs. Do not ignore traffic signs which are not displayed by the system. The system does not discern any signs other than the conventional traffic signs that might give or end a speed limit. It may not detect some electronic speed signs. Depending on the weather conditions or problems with traffic signs, a traffic sign may not be recognised or a sign different from the actual traffic sign may be displayed. Do not let this special feature tempt you into taking risks when driving. Always adapt vehicle speed to the road conditions. (Continued) Caution (Continued) Driver assistance systems do not relieve the driver from full responsibility for vehicle operation. Traffic signs that are detected are: . Construction Zones . Speed Limit . School Zone . Constraint Signs Display Indication The currently detected speed limit is displayed in the DIC until the next speed limit or end of speed limit sign is detected. The current valid speed limit is displayed permanently in the lower line of the DIC or upper left of the instrument cluster, depending on the vehicle. If a speed sign with an add on sign is detected, a 1 symbol is also displayed. Alert Function The alert function can be turned on or off from the Traffic Sign Memory page. See Driver Information Centre (DIC) 0 106. Once activated, and if the Traffic Sign Memory page is currently not displayed, a newly detected speed limit is briefly displayed as a pop-up alert in the DIC. Exceeding Indicated Speed Limit If the indicated traffic sign speed limit is exceeded by 5 km/h (3 mph) or more, the permanently displayed traffic sign symbol will flash until the vehicle speed is reduced to or below the indicated speed limit. System Reset The content of the traffic sign display can be cleared in the Traffic Sign Menu from the Traffic Sign Memory page by selecting Reset and confirmed by pressing the thumbwheel. The indication of multiple signs on the display is possible. A (–) symbol in a frame indicates there is a sign detected which cannot be clearly identified by the system. Upon successful reset, a (–) symbol displays until the next traffic sign is detected or provided by the navigation system map data. In some cases, traffic sign memory is cleared automatically by the system. See Driver Information Centre (DIC) 0 106. See Driver Information Centre (DIC) 0 106. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating Navigation System Traffic Sign Detection The currently displayed sign can either originate from sign detection using the camera, or from the navigation system map data. If the currently displayed sign originates from map data and the map information changes, a new sign will be displayed. This may lead to detection of a new sign, although no sign on the road may have been passed. Limitations Traffic sign memory may not operate correctly if: . The area of the windscreen, where the front camera is located, is not clean or is affected by foreign objects, e.g. stickers, window tinting, etc. . Traffic signs are completely or partially covered, are too low or high or difficult to discern. . Traffic signs are incorrectly mounted or are damaged. . Traffic signs do not comply with the approved traffic sign standards. . The speed limit is displayed by certain types of electronic speed signs. . There are adverse environmental conditions, e.g. heavy rain, snow, direct sunlight or shadows. . The headlights are dirty or not correctly aligned when driving at night. . The navigation map data is out of date. Lane Keep Assist (LKA) If equipped, LKA may help avoid crashes due to unintentional lane departures. This system uses a camera to detect lane markings. The LKA can be ready to assist at speeds between 60 km/h (37 mph) and 180 km/h (112 mph). On some vehicles, the system will instead operate above 50 km/h (31 mph). LKA may assist by gently turning the steering wheel if the vehicle approaches a detected lane marking. It may also provide a Lane Departure Warning (LDW) alert if the vehicle crosses a detected lane marking. This system is not intended to keep the vehicle centred in the lane. LKA will not assist and alert if the indicator is active in the direction of lane departure, or if it detects that you are accelerating, braking or actively steering. LKA can be overridden by turning the steering wheel. If the system detects you are steering intentionally across a lane 231 marker, the LDW may not be given. Do not expect the LDW to occur when you are intentionally crossing a lane marker. { 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. The LKA and LDW systems may not: . Provide an alert or enough steering assist to avoid a lane departure or crash. . Detect lane markings under poor weather or visibility conditions. This can occur if the windscreen or headlamps are blocked by dirt, snow or ice; if they are not in proper condition; or if the sun shines directly into the camera. . Detect road edges. . Detect lanes on winding or hilly roads. If LKA only detects lane markings on one side of the road, it will only assist or provide an LDW alert when approaching (Continued) Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 232 Driving and Operating Warning (Continued) the lane on the side where it has detected a lane marking. Even with LKA and LDW, you must steer the vehicle. Always keep your attention on the road and maintain proper vehicle position within the lane, or vehicle damage, injury or death could occur. Always keep the windscreen, headlamps and camera sensors clean and in good repair. Do not use LKA in bad weather conditions or on roads with unclear lane markings, such as construction zones. { Warning Using LKA on slippery roads could cause loss of control of the vehicle and a crash. Turn the system off. { Warning LKA will not alert the driver if a towed trailer crosses into an adjacent lane of travel. Serious injury or property damage may occur if the trailer moves into (Continued) Warning (Continued) another lane. Always monitor the trailer position while towing to make sure it is within the same lane as the towing vehicle. How the System Works LKA uses a camera sensor installed on the windscreen ahead of the rearview mirror to detect lane markings. It may provide brief steering assistance if it detects an unintended lane departure. It may further provide an audible alert, or the driver seat may pulse, indicating that a lane marking has been crossed. The system does not provide a Lane Departure Warning (LDW) when intentionally steering across a lane marker. To turn LKA on and off, press A on the centre console. If equipped, the indicator light on the button illuminates when LKA is on and turns off when LKA is disabled. In some vehicles a long press of over three seconds is required to turn LKA off. When activated, A is white, if equipped, indicating that the system is not ready to assist. A is green if LKA is ready to assist. LKA may assist by gently turning the steering wheel if the vehicle approaches a detected lane marking. A is amber when assisting. It may also provide a Lane Departure Warning (LDW) alert by flashing A amber if the vehicle crosses a detected lane marking. 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 The LKA system does not continuously steer the vehicle. If LKA does not detect active driver steering, an alert and chime may be provided. Steer the vehicle to dismiss. LKA may become temporarily unavailable after repeated false steering alerts. When the System Does Not Seem to Work Properly The system performance may be affected by: . Close vehicles ahead. . Sudden lighting changes, such as when driving through tunnels. . Banked roads. . Roads with poor lane markings, such as two-lane roads. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating If the LKA system is not functioning properly when lane markings are clearly visible, cleaning the windscreen may help. TOP TIER Logo or see www.toptiergas.com for a list of TOP TIER Detergent Gasoline resellers and applicable countries. A camera blocked message may display if the camera is blocked. 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 windscreen 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. Fuel Top Tier Fuel (Petrol) GM recommends the use of TOP TIER Detergent Gasoline to keep the engine clean, reduce engine deposits, and maintain optimal vehicle performance. Look for the 233 Recommended Fuel (Petrol) Use the recommended fuel for proper vehicle maintenance. Use unleaded petrol with a posted octane rating of 95 RON or higher and with ethanol up to 10% by volume. Unleaded petrol rated at 91 RON can be used, but acceleration and fuel economy will be reduced, and an audible knocking noise may be heard. If this occurs, use petrol rated at 95 RON as soon as possible. If heavy knocking is heard when using unleaded petrol rated at 95 RON, the engine needs service. Prohibited Fuels (Petrol) Caution Do not use fuels with any of the following conditions; doing so may damage the vehicle and void its warranty: (Continued) Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 234 Driving and Operating Caution (Continued) . Fuel with any amount of methanol, methylal, ferrocene and aniline. These fuels can corrode metal fuel system parts or damage plastic and rubber parts. . Fuel containing metals such as methylcyclopentadienyl manganese tricarbonyl (MMT), which can damage the emissions control system and spark plugs. . Fuel with a posted octane rating of less than the recommended fuel. Using this fuel will lower fuel economy and performance, and may decrease the life of the emissions catalyst. Fuel Additives (Diesel) GM recommends the use of ACDelco Diesel Fuel conditioner. This will help maintain optimal engine performance. GM does not recommend other aftermarket diesel additives. In the event you refuel using low-quality diesel, GM recommends adding ACDelco Fuel System Treatment Plus-Diesel to the vehicle's fuel tank. ACDelco Fuel System Treatment Plus-Diesel can help clean engine deposits and is available at your GM dealership. Fuel Additives (Petrol) TOP TIER Detergent Gasoline is highly recommended for use with your vehicle. If your country does not have TOP TIER Detergent Petrol, add ACDelco Fuel System Treatment Plus-Petrol to the vehicle's petrol fuel tank at every oil change or 15 000 km (9,000 mi), whichever occurs first. TOP TIER Detergent Petrol and ACDelco Fuel System Treatment Plus-Petrol will help keep your vehicle's engine fuel deposit free and performing optimally. If you are unable to obtain ACDelco Fuel System Treatment Plus Gasoline, consult your retailer for the GM-approved additive available in your country. Fuel for Diesel Engines The selection of a high-quality fuel is important for maintaining optimum vehicle performance. Diesel fuel should meet or exceed the minimum requirements in the most current versions of the local fuel standards. Do not use fuel with more than 15 ppm sulphur. If available, use of diesel fuel with less sulphur is highly recommended for better emissions. In countries where 15 ppm or lower sulphur is not available, do not use diesel fuel with sulphur greater than 50 ppm. In these countries only, the vehicle is already designed to accommodate this level of sulphur. Caution Use of fuel that does not comply with the required technical standards may lead to engine power loss, increased wear, or engine damage and may void your warranty. Some improper fuels are: . Diesel fuel with the addition of petrol. . Diesel fuel mixed with engine oil or automatic gearbox fluid. (Continued) Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating Caution (Continued) . Triglyceride fuels, such as raw vegetable oil or animal fat, in any form, including with blends of diesel or biodiesel. . Marine diesel fuel and fuel oils. . Diesel-water emulsions, such as Aquazole. . Aftermarket diesel fuel additives, which contain alcohol, organo-metallic additives, or water emulsifiers. Caution If the vehicle is accidentally refuelled with petrol, do not continue driving the vehicle. Driving the vehicle will damage the fuel system. Have the vehicle towed to a qualified technician to have the petrol removed from the tank and fuel system. Refuel with Ultra Low Sulphur Diesel fuel. It is also recommended to have the fuel system flushed with Ultra Low Sulphur Diesel, to ensure all petrol is removed. Some conditions, such as dirty fuel, may decrease fuel filter life and a CHANGE FUEL FILTER message may come on in the Driver Information Centre (DIC). Climate Grade Diesel Fuels At temperatures below 0 °C (32 °F), avoid using biodiesel blends above 7% by volume. Using such a fuel may cause fuel filter plugging, system gelling, and freezing, which may adversely affect vehicle starting. Severe winter grade diesel fuel, such as 1-D diesel fuel or Arctic grade diesel fuel, can be used in extreme cold temperatures (below −18 °C or 0 °F); however, doing so will reduce power and fuel economy. Avoid using severe winter grade fuel in warm or hot climates. It may result in stalling, poor starting, and damage to the fuel injection system. Fuels improperly blended for cold temperature operation may result in restricted fuel filters. The vehicle is equipped with a fuel heating system to prevent gelling or waxing of conventional diesel fuel and biodiesel blends, but may not prevent all cases. 235 In the event of severe winter conditions, the fuel filter may become clogged by wax naturally present in the fuel. To unclog it, move the vehicle to a warm garage area and allow the filter to warm up. The fuel filter may need to be replaced. See Fuel Filter Replacement (Diesel) 0 239. Biodiesel Biodiesel is a renewable fuel produced from vegetable oils or animal fats that have been chemically modified to make it compatible with diesel fuel. Caution Do not use homemade biodiesel or home test kits because the quality cannot be verified by approved scientific methods. Do not use raw vegetable oil or other unmodified bio-oils, fats, or blends of vegetable oil with diesel. They could damage the fuel system and engine, and damage would not be covered by the vehicle warranty. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 236 Driving and Operating Biodiesel Blends Fuels with a biodiesel content up to 7% by volume may be used (e.g., named B7). Only use biodiesel blends up to 7% by volume that comply with your country's or region's fuel standards. Caution Do not use blends containing more than 7% by volume biodiesel. Any engine, fuel system, or exhaust after-treatment system damage would not be covered by the vehicle warranty. As a renewable fuel, biodiesel provides some environmental benefits. However, biodiesel has unique properties and needs to be handled differently than diesel fuel. Its use presents additional risks and may not be appropriate in all situations. Certain vehicle operating modes increase these risks and should be avoided. Biodiesel fuel quality degrades with time and exposure to high temperature more quickly than Ultra Low Sulphur Diesel fuel. More frequent refuelling provides the best opportunity to have a supply of fresh fuel. Storage at hot ambient temperatures will accelerate biodiesel degradation. Owners who use little fuel, or who have vehicles stored for extended periods of time, should avoid the use of biodiesel blended fuels above 5% by volume. When vehicles are stored for longer than one month, they should be run out of biodiesel to below one quarter tank, refuelled with biodiesel-free diesel fuel, and driven several kilometres (miles) before storage. Cold Weather Operation (Diesel) At temperatures below 0 °C (32 °F), avoid using biodiesel blends above 5% by volume. Using such a fuel may cause fuel filter plugging, system gelling, and freezing, which may adversely affect vehicle starting. Severe winter grade diesel fuel, such as 1-D diesel fuel or Arctic grade diesel fuel, can be used in extreme cold temperatures (below -18 °C or 0 °F); however, doing so will reduce power and fuel economy. Avoid using severe winter grade fuel in warm or hot climates. It may result in stalling, poor starting, and damage to the fuel injection system. Fuels improperly blended for cold temperature operation may result in restricted fuel filters. The vehicle is equipped with a fuel heating system to prevent gelling or waxing of conventional diesel fuel and biodiesel blends, but it may not prevent all cases. In severe winter conditions, the fuel filter may become clogged by wax naturally present in the fuel. To unclog it, move the vehicle to a warm garage area and allow the filter to warm up. The fuel filter may need to be replaced. See Fuel Filter Replacement (Diesel) 0 239. Water in Fuel (Diesel) Improper fuel tank inspection or cleaning, or contaminated fuel from suppliers, may cause water to be pumped into the fuel tank along with the diesel fuel. If a WATER IN FUEL message displays in the DIC, the water must be drained immediately. { Warning Diesel fuel containing water is still combustible. You or others could be burned. If the fuel needs to be drained, keep sparks, flames, and smoking materials away from the mixture. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating Caution Water in the diesel fuel may corrode internal components of the fuel system and lead to severe damage. It may also support fungus or bacteria growth, which may damage the fuel system. Even with a diesel fuel biocide, the fuel system may still need to be cleaned. Your retailer can advise of the appropriate solution. If the fuel tank needs to be purged to remove water, see your retailer or a qualified technician. Improper purging may damage the fuel system. Water in Fuel Troubleshooting If a WATER IN FUEL message illuminates: Recommended Problem Action Message displays The fuel filter is but turns off during approximately half the ignition cycle. full of water. Drain the water immediately. See "Removing Water from the Fuel Filter" later in this section. Problem Message displays and stays on. Recommended Action Drain the fuel filter immediately. If no water can be drained, and the temperature is below freezing, then water may be frozen in the filter. Move the vehicle to a warm location to thaw the water, and then drain the fuel. If water still does not drain, see your retailer. 237 Recommended Action Problem Immediately after refuelling, message displays and stays on. A large amount of water is in the fuel tank. Drain the fuel filter immediately. If the message remains illuminated, or illuminates again without refuelling, then fuel tank purging is required. See your dealer. If the message displays and the vehicle stalls or running is rough, do not drive until the water-contaminated fuel is drained. Caution Driving with this message on may damage the fuel injection system and the engine. If the message illuminates (Continued) Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 238 Driving and Operating Caution (Continued) directly after refuelling, water has been pumped into the fuel tank. Turn off the engine and drain the water immediately. Removing Water from the Fuel Filter To drain water: 1. Turn the engine off and apply the parking brake. 2. Place a container under the filter drain valve, which is on the bottom of the fuel filter. 4. With the engine turned off, press and hold ENGINE START/STOP without applying the brake for five seconds to place the vehicle in Service Mode. See Ignition Positions 0 180. Wait approximately five seconds, and then press ENGINE START/STOP again to turn it off. This operation will enhance water flow out of the filter. The filter is drained as soon as diesel fuel emerges from the port. 5. Retighten the drain plug by turning it clockwise. 6. Properly dispose of the water-contaminated fuel. 7. Start the engine and let it run for a few minutes. During the draining process, air may have entered the fuel system. If the engine stalls, the fuel system may need to be primed. See “Fuel Priming” following. Fuel Priming 3. Turn the drain plug anticlockwise using a suitable tool. For the fuel system to work properly, there must not be any air in the fuel lines. If air does enter, the engine may not start and the fuel lines will need to be primed before operating the vehicle. If air is present, the following may have occurred: . The vehicle has run out of fuel. . The fuel filter was removed. . The fuel lines were removed or disconnected. . The fuel filter water drain valve was opened while the engine was running. To prime the fuel lines: 1. With the engine turned off, press and hold ENGINE START/STOP without applying the brake for five seconds to place the vehicle in Service Mode.

Trailer Towing General Towing Information Only use towing equipment that has been designed for the vehicle. Contact your retailer or trailer retailer for assistance with preparing the vehicle to tow a trailer. Read the entire section before towing a trailer. To tow a disabled vehicle, see Transporting a Disabled Vehicle 0 313. 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 (Continued) 243 Warning (Continued) 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. Trailer towing means changes in handling, acceleration, braking, durability, and fuel economy. Successful, safe trailering takes correct equipment, and it has to be used properly. The following information has many time-tested, important trailering tips and safety rules. Many of these are important for your safety and that of your passengers. Read this section carefully before pulling a trailer. When towing a trailer: . Become familiar with and follow all state and local laws that apply to trailer towing. These requirements vary from state to state. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 244 Driving and Operating . State laws may require the use of . . . . extended side view mirrors. If your visibility is limited or restricted while towing, install extended side view mirrors, even if not required. 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. GM recommends performing an oil change to the vehicle before heavy towing. Do not drive over 80 km/h (50 mph) and do not make starts at full throttle during the first 800 km (500 mi) of trailer towing. Vehicles can tow in D (Drive). If the transmission downshifts too often, a lower gear may be selected using Manual Mode. See Manual Mode 0 194. If equipped, the following driver assistance features should be turned off when towing a trailer: . Adaptive Cruise Control (ACC) . Super Cruise Control . Park Assist . Automatic Parking Assist (APA) . Reverse Automatic Braking (RAB) If equipped, the following driver assistance features should be turned to alert or off when towing a trailer: . Automatic Emergency Braking (AEB) . 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), exercise caution while reversing 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. { Warning To prevent serious injury or death from carbon monoxide (CO) when towing a trailer: . Do not drive with the tailgate, boot/ hatch, or rear-most window open. (Continued) Warning (Continued) . Fully open the air outlets on or under the instrument panel. . Adjust the climate control system to a setting that only allows in outside air. See “Climate Control Systems” in the Index. For more information about carbon monoxide, see Engine Exhaust 0 186. Towing a trailer requires experience. The combination of the vehicle and trailer is longer and not as responsive as the vehicle itself. Become familiar to the handling and braking by driving on a level road surface before driving on public roads. The trailer structure, the tyres, and the brakes must all be rated to carry the intended load. 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, tyres, and mirrors. See Towing Equipment 0 249. If the trailer has electric brakes, start the combination moving and then manually apply the trailer brake controller to check that the trailer Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating brakes work. During the trip, occasionally check that the load and trailer are secure and that the lamps and any trailer brakes are working. Towing with a Stability Control System When towing, the stability control system might be heard. The system reacts to vehicle movement caused by the trailer, which mainly occurs during cornering. This is normal when towing heavier trailers. 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. Overtaking More overtaking 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. You need to drive much farther beyond the overtaken vehicle before turning back into the lane. Overtaking on level roadways. Avoid overtaking on hills if possible. Reversing 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 reverse slowly and, if possible, have someone guide you. Making Turns Caution Turn more slowly and make wider arcs when towing a trailer to prevent damage to your vehicle. Making very sharp turns could cause the trailer to make contact with the vehicle. Make wider turns than normal when towing, so the trailer does not go over soft shoulders, over kerbs, or collide with road signs, trees, or other objects. Always indicate turns well in advance. Do not steer or brake suddenly. Driving on Grades Reduce speed and change 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. 245 The vehicle can tow in D (Drive). Shift the transmission to a lower gear if the transmission shifts too often under heavy loads and/or hilly conditions. 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 0 268. Parking on Hills { Warning To prevent serious injury or death, always park your vehicle and trailer on a level surface when possible. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 246 Driving and Operating When parking your vehicle and your trailer on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn the wheels into the curb if facing downhill or into traffic if facing uphill. 2. Have someone place chocks under the trailer wheels. 3. When the wheel chocks are in place, gradually release the brake pedal to allow the chocks to absorb the load of the trailer. 4. Reapply the brake pedal. Then apply the parking brake and shift into P (Park). 5. Release the brake pedal. Leaving After Parking on a Hill 1. Apply and hold the brake pedal. . Start the engine. . Shift into the desired gear. . Release the parking brake. 2. Release 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. Maintenance When Trailer Towing The vehicle needs to be serviced more often when used to tow trailers. See Maintenance Schedule (Petrol) 0 324 or Maintenance Schedule (Diesel) 0 326. It is especially important to check the automatic gearbox fluid, engine oil, axle lubricant, belts, cooling system, and brake system before and during each trip. Check periodically that all nuts and bolts on the trailer hitch are tight. Engine Cooling When Trailer Towing The cooling system may temporarily overheat during severe operating conditions. See Engine Overheating 0 268. Trailer Towing Caution Towing a trailer improperly can damage the vehicle and result in costly repairs not covered by the vehicle warranty. To tow a trailer correctly, follow the directions in this section and see your retailer for important information about towing a trailer with the vehicle. Trailering is different than just driving the vehicle by itself. Trailer towing means changes in handling, acceleration, braking, durability, and fuel economy. Successful, safe trailering takes correct equipment, and it has to be used properly. The following information has many time-tested, important trailering tips and safety rules. Many of these are important for your safety and that of your passengers. Read this section carefully before pulling a trailer. Trailer Weight { Warning Never exceed the towing capacity for your vehicle. Safe trailer towing requires monitoring of the weight, speed, altitude, road gradients, outside temperature, dimensions of the front of the trailer, and how frequently the vehicle is used to tow a trailer. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating Trailer Weight Ratings When towing a trailer, the combined weight of the vehicle, vehicle contents, trailer, and trailer contents must be below all of the maximum weight ratings for the vehicle including: . Gross Combined Weight Rating (GCWR) . Gross Vehicle Weight Rating (GVWR) . Maximum Trailer Weight Rating . Gross Axle Weight Rating-Rear (GAWR-RR) . Maximum Trailer Tongue Weight Rating See “Weight-Distributing Hitch Adjustment” under Towing Equipment 0 249 to determine if equalizer bars are required to obtain the maximum trailer weight rating. See “Trailer Brakes” under Towing Equipment 0 249 to determine if brakes are required based on the trailer weight. The only way to be sure that the weight does not exceed any of these ratings is to weigh the towing vehicle and trailer combination, fully loaded for the trip, getting individual weights for each of these items. { Warning You and others could be seriously injured or killed if the trailer is too heavy or the trailer brakes are inadequate for the load. The vehicle may be damaged, and the repairs would not be covered by the vehicle warranty. Only tow a trailer if all the steps in this section have been followed. Ask your retailer for advice and information about towing a trailer. Gross Combined Weight Rating (GCWR) GCWR is the total allowable weight of the completely loaded vehicle and trailer including any fuel, passengers, cargo, equipment, and accessories. Do not exceed the GCWR for your vehicle. The GCWR for the vehicle is in the following Tow Rating Chart. Gross Vehicle Weight Rating (GVWR) For information about the vehicle's maximum load capacity, see Vehicle Load Limits 0 176. When calculating the GVWR with a trailer attached, the trailer tongue weight must be included as part of the weight the vehicle is carrying. 247 Maximum Trailer Weight The maximum trailer weight rating is calculated assuming the towing vehicle has a driver, a front seat passenger, and all required trailer towing equipment. This value represents the heaviest trailer the vehicle can tow, but it may be necessary to reduce the trailer weight to stay within the GCW, GVWR, maximum trailer tongue load, or GAWR-RR for the vehicle. Use the tow rating chart to determine how much the trailer can weigh, based on the vehicle model and options. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 248 Driving and Operating Vehicle Maximum Trailer Weight GCWR* Maximum Tongue Weight 2.0L L4 Petrol Engine (LSY) 1 800 kg (3968 lb) 4175 kg (9204 lb) 72 kg (159 lb) 2.0L L4 Petrol Engine (LSY) with Heavy Duty Cooling System (V08) 2000 kg (4409 lb) 4375 kg (9645 lb) 80 kg (176 lb) 2.0L L4 Diesel Engine (LSQ) 1 600 kg (3,527 lb) 3 965 kg (8,740 lb) 64 kg (141 lb) *The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle and trailer including any passengers, cargo, equipment, and conversions. The GCWR for the vehicle should not be exceeded. allowable tongue weight the vehicle can carry, which also reduces the maximum allowable trailer weight. Maximum Trailer Tongue Weight Rating The Maximum Trailer Tongue Weight Rating is the allowable trailer tongue weight that the vehicle can support using a conventional trailer hitch. It may be necessary to reduce the overall trailer weight to stay within the maximum trailer tongue weight rating while still maintaining the correct trailer load balance. Trailer Load Balance The correct trailer load balance must be maintained to ensure trailer stability. Incorrect load balance is a leading cause of trailer sway. The trailer tongue weight contributes to the Gross Vehicle Weight (GVW). GVW includes the kerb weight of your vehicle, any passengers, cargo, equipment and the trailer tongue weight. Vehicle options, passengers, cargo, and equipment reduce the maximum Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating weight is too high or too low, it may be possible to rearrange some of the cargo inside the trailer. Do not exceed the maximum allowable tongue weight for your vehicle. Use the shortest hitch extension available to position the hitch ball closer to your vehicle. This will help reduce the effect of the trailer tongue weight on the trailer hitch and the rear axle. The trailer tongue weight (1) should be 4% of the total loaded trailer weight (2). Some specific trailer types, such as boat trailers, fall outside of this range. Always refer to the trailer owner's manual for the recommended trailer tongue weight for each trailer. Never exceed the maximum loads for your vehicle, hitch and trailer. The trailer load balance percentage is calculated as: weight (1) divided by weight (2) times 100. 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 If a cargo carrier is used in the trailer hitch receiver, choose a carrier that positions the load as close to the vehicle as possible. Make sure the total weight, including the carrier, is no more than half of the maximum allowable tongue weight for the vehicle or 227 kg (500 lb), whichever is less. For additional assistance with towing or additional information, see your retailer. Towing Equipment Hitches If equipped with trailer towing, the vehicle has a factory installed swivel style trailer hitch with an integrated ball neck. Hitch Cover Ask your retailer for trailer towing information or assistance. Rear Gross Axle Weight Rating (GAWR-RR) The GAWR-RR is the total weight that can be supported by the rear axle of the vehicle. Do not exceed the GAWR-RR for the vehicle, with the tow vehicle and trailer fully loaded for the trip including the weight of the trailer tongue. If using a weight-distributing hitch, do not exceed the GAWR-RR before applying the weight distribution spring bars. 249 To remove hitch cover, if equipped: 1. Remove the two fasteners on the lower tabs. 2. Pull the lower edge of the cover to about a 45 degree angle. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 250 Driving and Operating 3. Pull the cover downward to disengage the upper attachments. To reinstall the hitch cover: 1. Hold the cover at a 45 degree angle to the vehicle and push the upper tabs into the slots in the bumper. 2. Push the bottom of the cover forward until the lower tabs line up with the lower slots. 3. Snap the hitch cover into place by pushing the upper corners forward. 4. Reinstall the two fasteners on the lower tabs. Trailer Hitch Never unlock the hitch ball neck while towing or with an accessory attached. If the warning buzzer does not stop, do not use the hitch and have it checked and serviced to ensure it is safe to use. coupler latched to the hitch ball, or a tow eye latched to a pintle hook. Other trailers may require a weight-distributing hitch that uses spring bars to distribute the trailer tongue weight between your vehicle and trailer axles. See “Maximum Trailer Tongue Weight” under Trailer Towing 0 246 for weight limits with various hitch types. Consider using mechanical sway controls with any trailer. Ask a trailering professional about sway controls or refer to the trailer manufacturer's recommendations and instructions. Never attach rental hitches or other bumper-type hitches. Only use frame-mounted hitches that do not attach to the bumper. 1. Remove the hitch cover. See “Hitch Cover” above. To use the factory installed hitch: Always use the correct hitch equipment for your vehicle. Crosswinds, large trucks going by, and rough roads can affect the trailer and the hitch. Proper hitch equipment for your vehicle helps maintain control of the vehicle-trailer combination. Many trailers can be towed using a weight-carrying hitch which has a 2. Pull the handle to unlock the ball neck from the stowed position. The ball neck will partially pivot down. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating A warning buzzer will sound while the ball neck is unlocked. 3. Pull the ball neck rearward until it locks with the ball centred and pointing up. A click should be heard and the warning buzzer will stop. To stow the hitch: 1. Pull on the handle to unlock the ball neck. The warning buzzer will sound while the ball neck is unlocked. 2. Push the ball neck forward and up until it locks into place. The warning buzzer will stop when the ball neck is locked. Tyres . Do not tow a trailer while using a compact spare tyre on the vehicle. . Tyres must be properly inflated to support loads while towing a trailer. See Tyres 0 286 for instructions on proper tyre inflation. Safety Chains Always attach chains between the vehicle and the trailer, and attach the chains to the holes on the trailer hitch platform. 251 Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. anti-lock brakes and the trailer brakes may not function, which could result in a collision. 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. Trailer Wiring Harness Trailer Brakes Loaded trailers over 450 kg (1,000 lb) must be equipped with brake systems and with brakes for each axle. Trailer braking equipment conforming to Canadian Standards Association (CSA) requirement CAN3-D313, or its equivalent, is recommended. Regional 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 region to region. 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 Basic Trailer Wiring The trailer wiring harness is located at the rear of the vehicle and is tied to the vehicle's frame. The harness connector can be plugged into a trailer connector available through your retailer. The swivel-style factory installed hitch has a standard 13-pin connector integrated into the ball neck that is accessible when the hitch cover is removed and the hitch is deployed. Trailer Lamps Always check that all trailer lamps are working at the beginning of each trip, and periodically on longer trips. Turn Signals When Towing a Trailer When properly connected, the trailer indicators 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. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 252 Driving and Operating Trailer Sway Control (TSC) Vehicles with StabiliTrak/Electronic Stability Control (ESC) have a Trailer Sway Control (TSC) feature. Trailer sway is unintended side-to-side motion of a trailer while towing. If the vehicle is towing a trailer and the TSC detects that sway is increasing, the vehicle brakes are selectively applied at each wheel, to help reduce excessive trailer sway. If equipped with the Integrated Trailer Brake Control (ITBC) system, and the trailer has an electric brake system, StabiliTrak/ESC may also apply the trailer brakes. { Warning Trailer sway can result in a crash and in serious injury or death, even if the vehicle is equipped with TSC. If the trailer begins to sway, reduce vehicle speed by gradually removing your foot from the accelerator. Then pull over to check the trailer and vehicle to help correct possible causes, including an improperly or overloaded trailer, unsecured load, improper trailer hitch configuration, or improperly inflated or incorrect vehicle or trailer tyres. See Towing Equipment 0 249 for trailer ratings and hitch setup recommendations. Trailer Tyres If TSC is enabled, the Traction Control System (TCS)/StabiliTrak/ESC warning light will flash on the instrument cluster. Reduce vehicle speed by gradually removing your foot from the accelerator. If trailer sway continues, StabiliTrak/ESC can reduce engine torque to help slow the vehicle. TSC will not function if StabiliTrak/ESC is turned off. See Traction Control/Electronic Stability Control 0 198. Special Trailer (ST) tyres differ from vehicle tyres. Trailer tyres 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 tyre pressures are low only based on a visual inspection. Always check all trailer tyre pressures before each trip when the tyres are cool. Low trailer tyre pressure is a leading cause of trailer tyre blowouts. Trailer tyres deteriorate over time. The trailer tyre sidewall will show the week and year the tyre was manufactured. Many trailer tyre manufacturers recommend replacing tyres more than six years old. Overloading is another leading cause of trailer tyre blowouts. Never load your trailer with more weight than the tyres are designed to support. The load rating is located on the trailer tyre sidewall. Always know the maximum speed rating for the trailer tyres before driving. This may be significantly lower than the vehicle tyre speed rating. The speed rating may be on the trailer tyre sidewall. If the speed rating is not shown, the default trailer tyre speed rating is 105 km/h (65 mph). Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Driving and Operating 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 97. A device connected to the DLC — such as an aftermarket fleet or driver-behaviour tracking device — may interfere with vehicle systems. This could affect vehicle operation and cause a crash. Such devices may also access information stored in the vehicle's systems. Caution Some electrical equipment can damage the vehicle or cause components not to 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.

See Jump Starting 0 311. 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” in this section. . Change the engine oil at the appropriate time. See Engine Oil Life System 0 262. . Always dispose of engine oil properly. See “What to Do with Used Oil” in this section. Checking Engine Oil Check the engine oil level regularly, every 650 km (400 mi), especially prior to a long trip. The engine oil dipstick handle is a loop. See Engine Compartment Overview 0 257 for the location. { Warning When to Add Engine Oil 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 Centre (DIC) message displays, check the oil level. Follow these guidelines: . To get an accurate reading, park the vehicle on level ground. Check the engine oil level after the engine has been off for at least two hours. Checking the engine oil level on steep gradients 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. LSY 2.0L L4 Turbo Engine LSQ 2.0L L4 Turbo Diesel Engine 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 0 335. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Vehicle Care Caution Specification 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 rises above the cross-hatched area that shows the correct operating range), the engine could be damaged. Drain the excess oil or limit driving the vehicle, and seek help from a service professional to remove the excess oil. Use fully synthetic engine oils that meet the dexos1 specification. See Engine Compartment Overview 0 257 for the location of the engine oil fill cap. Caution Add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when done. Selecting the Right Engine Oil (Petrol Engine) Selecting the right engine oil depends on both the proper oil specification and viscosity grade. See Recommended Fluids and Lubricants 0 330. Engine oils that have been approved by GM as meeting the dexos1 specification are marked with the dexos1 approved logo. See www.gmdexos.com. Selecting the Right Engine Oil (Diesel Engine) Selecting the right engine oil depends on both the proper oil specification and viscosity grade: Specification Use engine oils that meet the dexosD specification. Engine oils that have been approved by GM as meeting the dexosD specification are marked with the dexosD approved logo. See www.gmdexos.com. 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-20 viscosity grade engine oil.

Brakes Disc brake linings have built-in wear indicators that make a high-pitched warning sound when the brake linings are worn and new linings are needed. The sound can come and go or can be heard all the time when the vehicle is moving, except when applying the brake pedal firmly. { Warning The brake wear warning sound means that soon the brakes will not work well. That could lead to a crash. When the brake wear warning sound is heard, have the vehicle serviced. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 270 Vehicle Care Caution Continuing to drive with worn-out brake linings could result in expensive brake repairs. Some driving conditions or climates can cause brake squeal when the brakes are first applied, which clears up following several brake applications. This does not mean something is wrong with the brakes. Replacing Brake System Parts Always replace brake system parts with new, approved replacement parts. If this is not done, the brakes may not work properly. The braking performance can change in many ways if the wrong brake parts are installed or if parts are improperly installed. Brake Fluid Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tyres are rotated, inspect the brake linings for wear and evenly tighten wheel nuts in the correct sequence to torque specifications. See Capacities and Specifications 0 335. Brake pads should be replaced as complete axle sets. Brake Pedal Travel See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign that brake service may be required. The brake master cylinder reservoir is filled with GM approved DOT 4 brake fluid as indicated on the reservoir cap. See Engine Compartment Overview 0 257 for the location of the reservoir. Checking Brake Fluid With the vehicle in P (Park) on a level surface, the brake fluid level should be between the minimum and maximum marks on the brake fluid reservoir. There are only two reasons why the brake fluid level in the reservoir may go down: . Normal brake lining wear. When new linings are installed, the fluid level goes back up. . A fluid leak in the brake hydraulic system. Have the brake hydraulic system fixed. With a leak, the brakes will not work well. Always clean the brake fluid reservoir cap and the area around the cap before removing it. Do not top off the brake fluid. Adding fluid does not correct a leak. If fluid is added when the linings are worn, there will be too much fluid when new brake linings are installed. Add or remove fluid, as necessary, only when work is done on the brake hydraulic system. { Warning If too much brake fluid is added, it can spill on the engine and burn, if the engine is hot enough. You or others could be burned, and the vehicle could be damaged. Add brake fluid only when work is done on the brake hydraulic system. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Vehicle Care When the brake fluid falls to a low level, the brake warning light comes on. See Brake System Warning Light 0 98. 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 (Petrol) 0 324 or Maintenance Schedule (Diesel) 0 326. What to Add Use only GM approved DOT 4 brake fluid from a clean, sealed container. See Recommended Fluids and Lubricants 0 330. { Warning The wrong or contaminated brake fluid could result in damage to the brake system. This could result in the loss of braking leading to a possible injury. Always use the proper GM approved brake fluid. Caution If brake fluid is spilled on the vehicle's painted surfaces, the paint finish can be damaged. Immediately wash off any painted surface. 271 charger, to limit charge voltage to 14.8 volts.

(Continued) Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Vehicle Care . . . . . Warning (Continued) Overloading the tyres can cause overheating as a result of too much flexing. There could be a blowout and a serious crash. See Vehicle Load Limits 0 176. Underinflated tyres pose the same danger as overloaded tyres. The resulting crash could cause serious injury. Check all tyres frequently to maintain the recommended pressure. Tyre pressure should be checked when the tyres are cold. Overinflated tyres are more likely to be cut, punctured, or broken by a sudden impact - such as when hitting a pothole. Keep tyres at the recommended pressure. Worn or old tyres can cause a crash. If the tread is badly worn, replace them. Replace any tyres that have been damaged by impacts with potholes, curbs, etc. (Continued) Warning (Continued) . Improperly repaired tyres can cause a crash. Only your dealer or an authorised tyre service centre should repair, replace, remove, and reinstall the tyres. . Do not spin the tyres in excess of 56 km/h (35 mph) on slippery surfaces such as snow, mud, ice, etc. Excessive spinning may cause the tyres to explode. See Tyre Pressure for High-Speed Operation 0 289 for inflation pressure adjustment for high-speed driving. Winter Tyres This vehicle was not originally equipped with winter tyres. Winter tyres are designed for increased traction on snow and ice-covered roads. Consider installing winter tyres on the vehicle if frequent driving on ice or snow covered roads is expected. See your dealer for details regarding winter tyre availability and proper tyre selection. Also, see Buying New Tyres 0 296. 287 With winter tyres, there may be decreased dry road traction, increased road noise and shorter tread life. After changing to winter tyres, be alert for changes in the vehicle handling and braking. If using winter tyres: . Use tyres of the same brand and tread type on all four wheel positions. . Use only radial ply tyres of the same size, load range and speed rating as the original equipment tyres. Winter tyres with the same speed rating as the original equipment tyres may not be available for H, V, W, Y and ZR speed rated tyres. If winter tyres with a lower speed rating are chosen, never exceed the tyre's maximum speed capability. Summer Tyres This vehicle may come with 235/55R18 or 245/45R20 high performance summer tyres. These tyres have a special tread and compound that are optimised 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 tyres be installed on the vehicle if frequent driving at temperatures below Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 288 Vehicle Care approximately 5 °C (40 °F) or on ice or snow covered roads is expected. See Winter Tyres 0 287. 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. If the tires have been subjected to -7 °C (20 °F) or less, let them warm up in a heated space to at least 5 ° C (40 °F) for 24 hours or more before being installed or driving a vehicle on which they are installed. Do not apply heat or blow heated air directly on the tyres. Always inspect tyres before use. See Tyre Inspection 0 294. Tyre Pressure Tyres need the correct amount of air pressure to operate effectively. { Warning Neither tyre underinflation nor overinflation is good. Underinflated tyres, or tyres that do not have enough air, can result in: . Tyre overloading and overheating, which could lead to a blowout . Premature or irregular wear . Poor handling . Reduced fuel economy for internal combustion engine vehicles . Reduced range for electric vehicles Overinflated tyres, or tyres that have too much air, can result in: . Unusual wear . Poor handling . Rough ride . Needless damage from road hazards The Tyre and Loading Information label on the vehicle indicates the original equipment tyres and the correct cold tyre inflation pressures. The recommended pressure is the minimum air pressure needed to support the vehicle's maximum load carrying capacity. See Vehicle Load Limits 0 176. 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 tyres once a month or more. Do not forget the spare, if the vehicle has one. The compact spare cold tyre pressure should be at 420 kPa (60 psi). See Compact Spare Tyre 0 310. How to Check Use a good quality pocket-type gauge to check tyre pressure. Proper tyre inflation cannot be determined by looking at the tyre. Check the tyre inflation pressure when the tyres are Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Vehicle Care 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 tyre valve stem. Press the tyre gauge firmly onto the valve to get a pressure measurement. If the cold tyre inflation pressure matches the recommended pressure on the Tyre 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 centre of the tyre valve to release air. Recheck the tyre pressure with the tyre gauge. Refit the valve caps on the valve stems to keep out dirt and moisture. Use only valve caps designed for the vehicle by GM. TPMS sensors could be damaged and would not be covered by the vehicle warranty. Tyre Pressure for High-Speed Operation { Warning Driving at high speeds, 160 km/h (100 mph) or higher, puts additional strain on tyres. Sustained high-speed driving causes excessive heat build-up and can cause sudden tyre failure. This could cause a crash, and you or others could be killed. Some high-speed rated tyres require inflation pressure adjustment for high-speed operation. When speed limits and road conditions allow the vehicle to be driven at high speeds, make sure the tyres are rated for high-speed operation, are in excellent condition, and are set to the correct cold tyre inflation pressure for the vehicle load. Vehicles with tyre sizes listed in the High Speed Operation Inflation Pressures table require inflation pressure adjustment when driving the vehicle at speeds of 160 km/h (100 mph) or higher. Set the cold tyre inflation pressure to the corresponding value in the table for the tyre size on the vehicle. 289 Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 290 Vehicle Care High Speed Operation Inflation Pressures Tyre Size Cold Inflation Pressure kPa (psi) 235/55R18 260 kPa (38 psi) 245/45R20 260 kPa (38 psi) Return the tyres to the recommended cold tyre inflation pressure when high-speed driving has ended. See Vehicle Load Limits 0 176 and Tyre Pressure 0 288. Tyre Pressure Monitor System Caution Modifications made to the Tyre Pressure Monitor System (TPMS) by anyone other than an authorised service facility may void authorisation to use the system. The Tyre Pressure Monitor System (TPMS) uses radio and sensor technology to check tyre pressure levels. The TPMS sensors monitor the air pressure in your vehicle's tyres and transmit tyre pressure readings to a receiver located in the vehicle. Each tyre, 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 tyre inflation pressure label. (If your vehicle has tyres of a different size than the size indicated on the vehicle placard or tyre inflation pressure label, you should determine the proper tyre inflation pressure for those tyres.) failure. Under-inflation also reduces energy efficiency and tyre tread life, and may affect the vehicle's handling and stopping ability. As an added safety feature, your vehicle has been equipped with a tyre pressure monitoring system (TPMS) that illuminates a low tyre pressure telltale when one or more of your tyres is significantly under-inflated. 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 tyre 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. Accordingly, when the low tyre pressure telltale illuminates, you should stop and check your tyres as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tyre causes the tyre to overheat and can lead to tyre Please note that the TPMS is not a substitute for proper tyre maintenance, and it is the driver's responsibility to maintain correct tyre pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tyre pressure telltale. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Vehicle Care When the malfunction indicator is illuminated, the system may not be able to detect or signal low tyre pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tyres or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tyres or wheels on your vehicle to ensure that the replacement or alternate tyres and wheels allow the TPMS to continue to function properly. See Tyre Pressure Monitor Operation 0 291 for additional information. See Declaration of Conformity 0 338. Tyre Pressure Monitor Operation This vehicle may have a Tyre Pressure Monitor System (TPMS). The TPMS is designed to warn the driver when a low tyre pressure condition exists. TPMS sensors are mounted onto each tyre and wheel assembly, excluding the spare tyre and wheel assembly. The TPMS sensors monitor the air pressure in the tyres and transmit the tyre pressure readings to a receiver located in the vehicle. 291 is driven. This could be an early indicator that the air pressure is getting low and needs to be inflated to the proper pressure. When a low tyre pressure condition is detected, the TPMS illuminates the low tyre pressure warning light on the instrument cluster. If the warning light comes on, stop as soon as possible and inflate the tyres to the recommended pressure shown on the Tyre and Loading Information label. See Vehicle Load Limits 0 176. A message to check the pressure in a specific tyre displays in the Driver Information Centre (DIC). The low tyre pressure warning light and the DIC warning message come on at each ignition cycle until the tyres are inflated to the correct inflation pressure. Using the DIC, tyre pressure levels can be viewed. For additional information and details about the DIC operation and displays see Driver Information Centre (DIC) 0 106. The low tyre pressure warning light may come on in cool weather when the vehicle is first started, and then turn off as the vehicle A Tyre and Loading Information label, attached to your vehicle, shows the size of the original equipment tyres and the correct inflation pressure for the tyres when they are cold. See Vehicle Load Limits 0 176 for an example of the Tyre and Loading Information label and its location. Also see Tyre Pressure 0 288. The TPMS can warn about a low tyre pressure condition but it does not replace normal tyre maintenance. See Tyre Inspection 0 294, Tyre Rotation 0 294, and Tyres 0 286. Caution Tyre sealant materials are not all the same. A non-approved tyre sealant could damage the TPMS sensors. TPMS sensor damage caused by using an incorrect tyre sealant is not covered by the vehicle warranty. Always use only the GM approved tyre sealant available through your dealer or included in the vehicle. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 292 Vehicle Care Factory-installed Tyre Inflater Kits use a GM-approved liquid tyre sealant. Using non-approved tyre sealants could damage the TPMS sensors. See Tyre Sealant and Compressor Kit 0 300 for information regarding the inflator kit materials and instructions. 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 tyre 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 tyres has been replaced with the spare tyre. The spare tyre does not have a TPMS sensor. The malfunction light and DIC message should go off after the road tyre is replaced and the sensor matching process is performed successfully. See “TPMS Sensor Matching Process” following. . The TPMS sensor matching process was not done or not completed successfully after rotating the tyres. The malfunction light and the DIC message should go off after successfully completing the sensor matching process. See "TPMS Sensor Matching Process" following. . One or more TPMS sensors are missing or damaged. The malfunction light and the DIC message should go off when the TPMS sensors are installed and the sensor matching process is performed successfully. See your dealer for service. . Replacement tyres or wheels do not match the original equipment tyres or wheels. Tyres and wheels other than those recommended could prevent the TPMS from functioning properly. See Buying New Tyres 0 296. . Operating electronic devices or being near facilities using radio wave frequencies similar to the TPMS could cause the TPMS sensors to malfunction. If the TPMS is not functioning properly, it cannot detect or signal a low tyre pressure condition. See your dealer for service if the TPMS malfunction light and DIC message come on and stay on. Tyre Fill Alert (If Equipped) This feature provides visual and audible alerts outside the vehicle to help when inflating an underinflated tyre to the recommended cold tyre pressure. When the low tyre pressure warning light comes on: 1. Park the vehicle in a safe, level place. 2. Apply the parking brake firmly. 3. Place the vehicle in P (Park). 4. Add air to the tyre that is underinflated. The indicator lamp will flash. When the recommended pressure is reached, the horn sounds once and the indicator lamp will stop flashing and briefly turn solid. Repeat these steps for all underinflated tyres that have illuminated the low tyre pressure warning light. { Warning Overinflating a tyre could cause the tyre to rupture and you or others could be injured. Do not exceed the maximum pressure listed on the tyre sidewall. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Vehicle Care If the tyre is overinflated by more than 35 kPa (5 psi), the horn will sound multiple times and the indicator lamp will continue to flash for several seconds after filling stops. To release and correct the pressure, while the indicator lamp is still flashing, briefly press the centre of the valve stem. When the recommended pressure is reached, the horn sounds once. If the indicator lamp does not flash within 15 seconds after starting to inflate the tyre, the tyre fill alert has not been activated or is not working. If the hazard warning flashers are on, the tyre fill alert visual feedback will not work properly. The TPMS will not activate the tyre 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 tyre. . There is a malfunction in the TPMS. . There is a malfunction in the horn or indicator lamps. . The identification code of the TPMS sensor is not registered to the system. . The battery of the TPMS sensor is low. If the tyre 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 tyre fill alert feature is not working, use a tyre pressure gauge. TPMS Sensor Matching Process Each TPMS sensor has a unique identification code. The identification code needs to be matched to a new tyre/wheel position after rotating the vehicle's tyres or replacing one or more of the TPMS sensors. The TPMS sensor matching process should also be performed after replacing a spare tyre with a road tyre 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 tyre/ wheel positions, using a TPMS relearn tool, in the following order: driver side front tyre, passenger side front tyre, passenger side rear tyre, and driver side rear tyre. See your dealer for service or to purchase a relearn tool. You have two minutes to match the first tyre/wheel position, and five minutes overall to match all four tyre/wheel positions. If it takes longer, the matching process stops and must be restarted. 293 The TPMS sensor matching process is outlined below: 1. Apply the parking brake. 2. Place the vehicle in Service Mode. See Ignition Positions 0 180. 3. Make sure the Tyre 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 Centre (DIC) 0 106. 4. Use the DIC controls on the right-hand side of the steering wheel to scroll to the Tyre Pressure screen under the DIC info page. 5. Press and hold the thumbwheel located in the centre of the DIC controls on the right-hand side of the steering wheel. The horn sounds twice to signal the receiver is in relearn mode and the TYRE LEARNING ACTIVE message displays on the DIC screen. 6. Start with the driver side front tyre. 7. Place the relearn tool against the tyre 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 tyre and wheel position. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 294 Vehicle Care 8. Proceed to the passenger side front tyre, and repeat the procedure in Step 7. 9. Proceed to the passenger side rear tyre, and repeat the procedure in Step 7. 10. Proceed to the driver side rear tyre, 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 tyre, and the TPMS sensor matching process is no longer active. The TYRE LEARNING ACTIVE message on the DIC display screen goes off. 11. Turn the vehicle off. 12. Set all four tyres to the recommended air pressure level as indicated on the Tyre and Loading Information label. Tyre Inspection We recommend that the tyres, including the spare tyre, if the vehicle has one, be inspected for signs of wear or damage at least once a month. Replace the tyre if: . The indicators at three or more places around the tyre can be seen. There is cord or fabric showing through the tyre's rubber. . The tread or sidewall is cracked, cut, or snagged deep enough to show cord or fabric. . The tyre has a bump, bulge, or split. . The tyre has a puncture, cut, or other damage that cannot be repaired well because of the size or location of the damage. . See When It Is Time for New Tyres 0 295 and Wheel Replacement 0 297. Tyre Rotation Tyres should be rotated according to the interval specified in the Maintenance Schedule. See Maintenance Schedule (Petrol) 0 324 or Maintenance Schedule (Diesel) 0 326. Tyres are rotated to achieve a more uniform wear for all tyres. The first rotation is the most important. Anytime unusual wear is noticed, rotate the tyres as soon as possible, check for proper tyre inflation pressure, and check for damaged tyres or wheels. If the unusual wear continues after the rotation, check the wheel alignment. Use this rotation pattern when rotating the tyres. Do not include the compact spare tyre in the tyre rotation. Adjust the front and rear tyres to the recommended inflation pressure on the Tyre and Loading Information label after the tyres have been rotated. See Tyre Pressure 0 288 and Vehicle Load Limits 0 176. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Vehicle Care Reset the Tyre Pressure Monitor System. See Tyre Pressure Monitor Operation 0 291. Check that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Specifications 0 335, and “Removing the Flat Tyre and Installing the Spare Tyre” under Tyre Changing 0 306. { Warning Rust or dirt on a wheel, or on the parts to which it is fastened, can cause wheel nuts to become loose over time. The wheel could come off and cause a crash. When changing a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, a cloth or paper towel can be used; however, use a scraper or wire brush afterwards to remove all rust or dirt. 295 Lightly coat the inner diameter of the wheel hub opening with wheel bearing grease after a wheel change or tyre rotation to prevent corrosion or rust build-up. { Warning Do not apply grease to the wheel mounting surface, wheel conical seats, or the wheel nuts or bolts. Grease applied to these areas could cause a wheel to become loose or detach, resulting in a collision. When It Is Time for New Tyres Factors, such as maintenance, temperatures, driving speeds, vehicle loading, and road conditions affect the wear rate of the tyres. Tread wear indicators are one way to tell when it is time for new tyres. Tread wear indicators appear when the tyres have only 1.6 mm (1/16 in) or less of tread remaining. See Tyre Inspection 0 294 and Tyre Rotation 0 294. The rubber in tyres ages over time. This also applies to the spare tyre, if the vehicle has one, even if it is never used. Multiple factors including temperatures, loading conditions, and inflation pressure maintenance affect how fast ageing takes place. GM recommends that tyres, including the spare if equipped, be replaced after six years, regardless of tread wear. To identify the age of a tyre, use the tyre manufacture date, which consists of the last four digits of the Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 296 Vehicle Care DOT Tyre Identification Number (TIN) moulded into one side of the tyre sidewall. The last four digits of the TIN indicate the tyre manufacture date. The first two digits indicate the week and the last two digits, the year. For example, the third week of the year 2020 would have a 4-digit DOT date of 0320. Week 01 is the first full week (Sunday to Saturday inclusive) of each year. Vehicle Storage Tyres 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 ageing. This area should be free of grease, petrol, or other substances that can deteriorate rubber. Parking for an extended period can cause flat spots on the tyres that may result in vibrations while driving. When storing a vehicle for at least a month, remove the tyres or raise the vehicle to reduce the weight from the tyres. Buying New Tyres GM has developed and matched specific tyres for the vehicle. The original equipment tyres installed were designed to meet General Motors Tyre Performance Criteria Specification (TPC Spec) system rating. When replacement tyres are needed, GM strongly recommends buying tyres 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 tyre pressure monitoring performance. GM's TPC Spec number is moulded onto the tyre's sidewall near the tyre size. If the tyres have an all-season tread design, the TPC Spec number will be followed by MS for mud and snow. GM recommends replacing worn tyres in complete sets of four. Uniform tread depth on all tyres will help to maintain the performance of the vehicle. Braking and handling performance may be adversely affected if all the tyres are not replaced at the same time. If proper rotation and maintenance have been done, all four tyres should wear out at about the same time. However, if it is necessary to replace only one axle set of worn tyres, place the new tyres on the rear axle. See Tyre Rotation 0 294. { Warning Tyres could explode during improper service. Attempting to mount or dismount a tyre could cause injury or death. Only your dealer or authorised tyre service centre should mount or dismount the tyres. { Warning Mixing tyres of different sizes (other than those originally installed on the vehicle), brands, tread patterns 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 tyre on all wheels. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Vehicle Care { Warning Using bias-ply tyres on the vehicle may cause the wheel rim flanges to develop cracks after many miles of driving. A tyre and/or wheel could fail suddenly and cause a crash. Use only radial-ply tyres with the wheels on the vehicle. Winter tyres with the same speed rating as the original equipment tyres may not be available for H, V, W, Y and ZR speed rated tyres. Never exceed the winter tyres' maximum speed capability when using winter tyres with a lower speed rating. If the vehicle tyres must be replaced with a tyre 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 tyres. The Tyre and Loading Information label indicates the original equipment tyres on the vehicle. See Vehicle Load Limits 0 176. Different Size Tyres and Wheels If wheels or tyres are installed that are a different size than the original equipment wheels and tyres, 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 tyres not recommended for those wheels are selected. This increases the chance of a crash and serious injury. Only use GM specific wheel and tyre systems developed for the vehicle, and have them properly installed by a GM certified technician. See Buying New Tyres 0 296 and Accessories and Modifications 0 255. 297 Wheel Alignment and Tyre Balance The tyres and wheels were aligned and balanced at the factory to provide the longest tyre life and best overall performance. Adjustments to wheel alignment and tyre balancing are not necessary on a regular basis. Consider an alignment check if there is unusual tyre 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 tyres 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 aluminium wheels can be repaired. See your dealer if any of these conditions exist. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 298 Vehicle Care Your dealer will know the kind of wheel that is needed. Each new wheel should have the same load-carrying capacity, diameter, width, offset, and be mounted the same way as the one it replaces. Replace wheels, wheel bolts, wheel nuts, or Tyre Pressure Monitor System (TPMS) sensors with new GM original equipment parts. { Warning Using the wrong replacement wheels, wheel bolts, or wheel nuts can be dangerous. It could affect the braking and handling of the vehicle. Tires can lose air and cause loss of control, resulting in a crash. Always use the correct wheel, wheel bolts, and wheel nuts for replacement. { 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. (Continued) Warning (Continued) It could fail suddenly and cause a crash. When replacing wheels, use a new GM original equipment wheel. 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 tyre or tyre chain clearance to the body and chassis. Tyre Chains { Warning If the vehicle has 245/45R20 size tyres, do not use tyre chains. There is not enough clearance. Tyre chains used on a vehicle without the proper amount of clearance can cause damage to the brakes, suspension or other vehicle parts. The area damaged by the tyre chains could cause loss of control and a crash. Use another type of traction device only if its (Continued) Warning (Continued) manufacturer recommends it for the vehicle's tyre size combination and road conditions. Follow that manufacturer's instructions. To avoid vehicle damage, drive slow and readjust or remove the traction device if it contacts the vehicle. Do not spin the wheels. If traction devices are used, install them on the front tyres. Caution If the vehicle is equipped with a tyre size other than 245/45R20, use tyre chains only where legal and only when necessary. Use low profile chains that add no more than 12 mm thickness to the tyre tread and inner sidewall. Use chains that are the proper size for the tyres. Install them on the tyres of the front axle. Do not use chains on the tyres of the rear axle. Tighten them as tightly as possible with the ends securely fastened. Drive slowly and follow the chain manufacturer's instructions. If the chains contact the vehicle, stop and retighten (Continued) Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Vehicle Care Caution (Continued) 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 Tyre Goes Flat It is unusual for a tyre to blow out while driving, especially if the tyres are maintained properly. See Tyres 0 286. If air goes out of a tyre, it is much more likely to leak out slowly. But if there is ever a blowout, here are a few tips about what to expect and what to do: If a front tyre fails, the flat tyre 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 tyre will cause permanent damage to the tyre. Re-inflating a tyre 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 tyre that has been driven on while severely underinflated or flat. Have your dealer or an authorised tyre service centre repair or replace the flat tyre as soon as possible. { 299 If a tyre goes flat, avoid further tyre and wheel damage by driving slowly to a level place, well off the road, if possible. Turn on the hazard warning flashers. See Hazard Lights 0 116. If your vehicle is loaded at or near maximum cargo capacity, it may be difficult to fit the jack under the vehicle due to the environment (shoulder slope, road debris etc.). Removal of some weight may improve the ability to fit the jack under the vehicle at the correct jacking location. { Warning Warning Lifting a vehicle and getting under it to do maintenance or repairs is dangerous without the appropriate safety equipment and training. If a jack is provided with the vehicle, it is designed only for changing a flat tyre. If it is used for anything else, you or others could be badly injured or killed if the vehicle slips off the jack. If a jack is provided with the vehicle, only use it for changing a flat tyre. Changing a tyre can be dangerous. The vehicle can slip off the jack and roll over or fall causing injury or death. Find a level place to change the tyre. To help prevent the vehicle from moving: 1. Apply the parking brake firmly. 2. Put the vehicle in P (Park). 3. Turn the vehicle off and do not restart the vehicle while it is raised. 4. Do not allow passengers to remain in the vehicle. (Continued) Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 300 Vehicle Care Warning (Continued) 5. Place wheel chocks, if equipped, on both sides of the tyre at the opposite corner of the tyre being changed. This vehicle may come with a jack and spare tyre or a tyre sealant and compressor kit. To use the jacking equipment to change a spare tyre safely, follow the instructions below. Then see Tyre Changing 0 306. To use the tyre sealant and compressor kit, see Tyre Sealant and Compressor Kit 0 300. When the vehicle has a flat tyre (2), use the following example as a guide to assist you in the placement of wheel chocks (1), if equipped. The following information explains how to repair or change a tyre. Tyre Sealant and Compressor Kit { Warning Idling a vehicle in an enclosed area with poor ventilation is dangerous. Engine exhaust may enter the vehicle. Engine exhaust contains carbon monoxide (CO) which cannot be seen or smelled. It can cause unconsciousness and even death. Never run the engine in an enclosed area that has no fresh air ventilation. For more information, see Engine Exhaust 0 186. { Warning Overinflating a tyre could cause the tyre to rupture and you or others could be injured. Be sure to read and follow the tyre sealant and compressor kit instructions and inflate the tyre to its recommended pressure. Do not exceed the recommended pressure. 1. Wheel Chock (If Equipped) 2. Flat Tyre { Warning Storing the tyre sealant and compressor kit or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store the tyre sealant and compressor kit in its original location. If this vehicle has a tyre sealant and compressor kit, there may not be a spare tyre or tyre changing equipment, and on some vehicles there may not be a place to store a tyre. The tyre sealant and compressor can be used to temporarily seal punctures up to 6 mm (0.25 in) in the tread area of the tyre. It can also be used to inflate an under inflated tyre. If the tyre has been separated from the wheel, has damaged sidewalls, or has a large puncture, the tyre is too severely damaged for the tyre sealant and compressor kit to be effective. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Vehicle Care 301 Using the Tyre Sealant and Compressor Kit to Temporarily Seal and Inflate a Punctured Tyre Read and follow all of the tyre sealant and compressor kit instructions.

The vehicle must be running while using the air compressor. 10. Press the on/off button (5) to turn the tyre sealant and compressor kit on. The compressor will inject sealant and air into the tyre. The pressure gauge (8) will initially show a high pressure while the compressor pushes the sealant into the tyre. Once the sealant is completely dispersed into the tyre, the pressure will quickly drop and start to rise again as the tyre inflates with air only. 11. Inflate the tyre to the recommended inflation pressure using the pressure gauge (8). The recommended inflation pressure can be found on the Tyre and Loading Information label. See Tyre Pressure 0 288. The pressure gauge (8) may read higher than the actual tyre pressure while the compressor is on. Turn the compressor Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 Vehicle Care off to get an accurate pressure reading. The compressor may be turned on/off until the correct pressure is reached. Caution If the recommended pressure cannot be reached after approximately 25 minutes, the vehicle should not be driven farther. The tyre is too severely damaged and the tyre sealant and compressor kit cannot inflate the tyre. Remove the power plug from the accessory power outlet and unscrew the inflating hose from the tyre valve. 12. Press the on/off button (5) to turn the tyre sealant and compressor kit off. The tyre is not sealed and will continue to leak air until the vehicle is driven and the sealant is distributed in the tyre. Therefore, Steps 13–21 must be done immediately after Step 12. Be careful while handling the tyre sealant and compressor kit as it could be warm after usage. 13. Unplug the power plug (9) from the accessory power outlet in the vehicle. 14.

Your retailer has trained technicians who can perform required maintenance using genuine replacement parts. They have up-to-date tools and equipment for fast and accurate diagnostics. Many dealers have extended evening and Saturday hours, courtesy transportation, and online scheduling to assist with service needs. Your retailer recognises the importance of providing competitively priced maintenance and repair services. With trained technicians, your retailer is the place for routine maintenance such as oil changes and tyre rotations and additional maintenance items like tyres, brakes, batteries, and wiper blades. 323 Caution Damage caused by improper maintenance can lead to costly repairs and may not be covered by the vehicle warranty. Maintenance intervals, checks, inspections, recommended fluids, and lubricants are important to keep the vehicle in good working condition. Do not have chemical flushes that are not approved by GM performed on the vehicle. The use of flushes, solvents, cleaners, or lubricants that are not approved by GM could damage the vehicle, requiring expensive repairs that are not covered by the vehicle warranty. The Tyre Rotation and Required Services are the responsibility of the vehicle owner. It is recommended that your retailer perform these services every 15 000 km. Proper vehicle maintenance helps to keep the vehicle in good working condition, improves fuel economy, and reduces vehicle emissions. Cadillac XT4 Owner Manual (GMNA-Localizing-Europe-16412942) - 2023 CRC - 5/25/22 324 Service and Maintenance Because of the way people use vehicles, maintenance needs vary.

Data Storage Modules in the Vehicle A large number of electronic components of your vehicle contain data storage modules temporarily or permanently storing technical data about the condition of the vehicle, events, and errors. In general, this technical information documents the condition of parts, modules, systems, or the environment: . Operating conditions of system components (e.g., filling levels). . Status messages of the vehicle and its single components (e.g., number of wheel revolutions/rotational speed, deceleration, lateral acceleration). . Dysfunctions and defects in important system components. . Vehicle reactions in particular driving situations (e.g., inflation of an airbag, activation of the stability regulation system). . Environmental concerns (e.g., temperature). If services are used (e.g., repair works, service processes, warranty cases, quality assurance), employees of the service network (manufacturer included) are able to read out this technical information from the event and error data storage modules applying special diagnostic devices. If required, you will receive further information at these dealers. After an error has been corrected, the data is deleted from the error storage module or constantly overwritten. When using the vehicle, situations may occur in which these technical data related to other information (crash report, damage to the vehicle, witness statements, etc.) may be associated with a specific person — possibly, with the assistance of an expert. In an emergency, your vehicle location and other data may be transmitted to emergency services in accordance with Directive (EU) 2015/758.
