There is more time to stop because you stop over a longer distance and, when worn properly, your strongest bones take the forces from the seat belts. That is why wearing seat belts makes such good sense. Questions and Answers About Seat Belts Q: Will I be trapped in the vehicle after a crash if I am wearing a seat belt? A: You could be — whether you are wearing a seat belt or not. Your chance of being conscious during and after a crash, so you can unbuckle and get out, is much greater if you are belted.

The best way to protect the fetus is to protect the mother. When a seat belt is worn properly, it is more likely that the fetus will not be hurt in a crash. For pregnant women, as for anyone, the key to making seat belts effective is wearing them properly. Periodically check the seat belt reminder, seat belts, buckles, latch plates, retractors, shoulder belt height adjusters (if equipped), and seat belt anchorages to make sure they are all in working order. Look for any other loose or damaged seat belt system parts that might keep a seat belt system from performing properly. See your dealer to have it repaired. Torn, frayed, or twisted seat belts may not protect you in a crash. Torn or frayed seat belts can rip apart under impact forces. If a belt is torn or frayed, have it replaced immediately. If a belt is twisted, it may be possible to untwist by reversing the latch plate on the webbing. If the twist cannot be corrected, ask your dealer to fix it. Safety System Check www.carobook.com Seat Belt Extender If the vehicle's seat belt will fasten around you, you should use it. But if a seat belt is not long enough, your dealer will order you an extender. When you go in to order it, take the heaviest coat you will wear, so the extender will be long enough for you. To help avoid personal injury, do not let someone else use it, and use it only for the seat it is made to fit. The extender has been designed for adults. Never use it for securing child restraints.

A frontal airbag for the driver . A frontal airbag for the front outboard passenger . A knee airbag for the driver . 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 center of the steering wheel for the driver and on the instrument panel for the front outboard passenger. For knee airbags, the word AIRBAG is on the lower part of the instrument panel. For seat-mounted side impact airbags, the word AIRBAG is on the side of the seatback or side of the seat closest to the door. { 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 63. For roof-rail airbags, the word AIRBAG is on the ceiling or trim. your seat belt during a www.carobook.com Wearing crash helps reduce your chance 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: 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. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Seats and Restraints { Warning Warning (Continued) Because airbags inflate with great force and faster than the blink of an eye, anyone who is up against, or very close to, any airbag when it inflates can be seriously injured or killed. Do not sit unnecessarily close to any airbag, as you would be if sitting on the edge of the seat or leaning forward. Seat belts help keep you in position before and during a crash. Always wear a seat belt, even with airbags. The driver should sit as far back as possible while still maintaining control of the vehicle. The seat belts and the front outboard passenger airbags are most effective when you are sitting well back and upright in the seat with both feet on the floor. (Continued) Occupants should not lean on or sleep against the door or side windows in seating positions with seat-mounted side impact airbags and/or roof-rail airbags. 61 There is an airbag readiness light on the instrument cluster, which shows the airbag symbol. The system checks the airbag electrical system for malfunctions. The light tells you if there is an electrical problem. See Airbag Readiness Light 0 119 for more information. 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 72 or Infants and Young Children 0 73. www.carobook.com The driver frontal airbag is in the center of the steering wheel. The front outboard passenger frontal airbag is in the passenger side instrument panel. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 62 Seats and Restraints { Warning The driver knee airbag is below the steering column. Driver Side Shown, Passenger Side Similar www.carobook.com The seat-mounted side impact airbags for the driver and front outboard passenger are in the sides of the seatbacks closest to the door. The roof-rail airbags for the driver, front outboard passenger, and second row outboard passengers are in the ceiling above the side windows. If something is between an occupant and an airbag, the airbag might not inflate properly or it might force the object into that person causing severe injury or even death. The path of an inflating airbag must be kept clear. Do not put anything between an occupant and an airbag, and 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. 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. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Seats and Restraints When Should an Airbag Inflate? It depends on what is hit, the direction of the impact, and how quickly the vehicle slows down. This vehicle is equipped with airbags. See Airbag System 0 60. 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 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 designed to inflate in moderate to severe frontal or near frontal crashes to help reduce the potential for severe injuries, mainly to the driver's or front outboard passenger's head and chest. Whether the frontal airbags will or should inflate is not based primarily on how fast the vehicle is traveling. Frontal airbags are not intended to inflate during vehicle rollovers, in rear impacts, or in many side impacts. www.carobook.com In addition, the vehicle has advanced technology frontal airbags. Advanced technology frontal airbags adjust the restraint according to crash severity. Knee airbags are designed to inflate in moderate to severe frontal or near frontal impacts. Knee airbags are not designed to inflate during vehicle rollovers, in rear impacts, or in many side impacts. Seat-mounted side impact airbags are designed to inflate in moderate to severe side crashes, depending 63 on the location of the impact. These airbags are also designed to inflate in some moderate to severe frontal or near-frontal impacts that could result in the occupant moving toward the side of the vehicle. 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 are designed to inflate during a rollover or in a severe frontal impact. Roof-rail airbags are not designed to inflate in rear impacts. Both roof-rail airbags will inflate when either side of the vehicle is struck, if the sensing system predicts that the vehicle is about to roll over on its side, or in a severe frontal impact. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 64 Seats and Restraints In any particular crash, no one can say whether an airbag should have inflated simply because of the vehicle damage or repair costs. What Makes an Airbag Inflate? In a deployment event, the sensing system sends an electrical signal triggering a release of gas from the inflator. Gas from the inflator fills the airbag causing the bag to break out of the cover. The inflator, the airbag, and related hardware are all part of the airbag module. For airbag locations, see Where Are the Airbags? 0 61. How Does an Airbag Restrain? In moderate to severe frontal or near frontal collisions, even belted occupants can contact the steering wheel or the instrument panel. In moderate to severe side collisions, even belted occupants can contact the inside of the vehicle. Airbags supplement the protection provided by seat belts by distributing the force of the impact more evenly over the occupant's body. Rollover capable roof-rail airbags are designed to help contain the head and chest of occupants in the outboard seating positions in the first and second rows. The rollover capable roof-rail airbags are designed to help reduce the risk of full or partial ejection in rollover events, although no system can prevent all such ejections. What Will You See after an Airbag Inflates? After frontal, knee, and seat-mounted side impact airbags inflate, they quickly deflate, so quickly that some people may not even realize the airbags inflated. Roof-rail airbags may still be at least partially inflated for some time after they inflate. Some components of the airbag module may be hot for several minutes. For location of the airbags, see Where Are the Airbags? 0 61. www.carobook.com 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 63. Airbags should never be regarded as anything more than a supplement to seat belts. The parts of the airbag that come into contact with you may be warm, but not too hot to touch. There may be some smoke and dust coming from the vents in the deflated airbags. Airbag inflation does not prevent the driver from seeing out of the windshield or being able to steer the vehicle, nor does it prevent people from leaving the vehicle. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Seats and Restraints { Warning When an airbag inflates, there may be dust in the air. This dust could cause breathing problems for people with a history of asthma or other breathing trouble. To avoid this, everyone in the vehicle should get out as soon as it is safe to do so. If you have breathing problems but cannot get out of the vehicle after an airbag inflates, then get fresh air by opening a window or a door. If you experience breathing problems following an airbag deployment, you should seek medical attention. The vehicle has a feature that may automatically unlock the doors, turn on the interior lamps and hazard warning flashers, and shut off the fuel system after the airbags inflate. The feature may also activate, without airbag inflation, after an event that exceeds a predetermined threshold. After turning the ignition off and then on again, the fuel system will return to normal operation; the doors can be locked, the interior lamps can be turned off, and the hazard warning flashers can be turned off using the controls for those features. If any of these systems are damaged in the crash they may not operate as normal. { Warning A crash severe enough to inflate the airbags may have also damaged important functions in the vehicle, such as the fuel system, brake and steering systems, etc. Even if the vehicle appears to be drivable after a moderate crash, there may be concealed damage that could make it difficult to safely operate the vehicle. www.carobook.com Use caution if you should attempt to restart the engine after a crash has occurred. 65 In many crashes severe enough to inflate the airbag, windshields are broken by vehicle deformation. Additional windshield breakage may also occur from the front outboard passenger airbag. . Airbags are designed to inflate only once. After an airbag inflates, you will need some new parts for the airbag system. If you do not get them, the airbag system will not be there to help protect you in another crash. A new system will include airbag modules and possibly other parts. The service manual for the vehicle covers the need to replace other parts. . The vehicle has a crash sensing and diagnostic module which records information after a crash. See Vehicle Data Recording and Privacy 0 367 and Event Data Recorders 0 367. .

See your dealer for service. Passenger Sensing System The vehicle has a passenger sensing system for the front outboard passenger position. The passenger airbag status indicator will light on the overhead console when the vehicle is started. The passenger sensing system turns off the front outboard passenger frontal airbag under certain conditions. No other airbag is affected by the passenger sensing system. The passenger sensing system works with sensors that are part of the front outboard passenger seat and seat belt. The sensors are designed to detect the presence of a properly seated occupant and determine if the front outboard passenger frontal airbag should be allowed to inflate or not. www.carobook.com The words ON and OFF, and the symbols for on and off, will be visible during the system check. When the system check is complete, either the word ON or OFF, and the symbol for on or off, will be visible. See Passenger Airbag Status Indicator 0 119. According to accident statistics, children are safer when properly secured in a rear seat in the correct child restraint for their weight and size. Whenever possible, children aged 12 and under should be secured in a rear seating position. Never put a rear-facing child seat in the front. This is because the risk to the rear-facing child is so great, if the airbag inflates. { Warning A child in a rear-facing child restraint can be seriously injured or killed if the passenger frontal airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag. A child in a forward-facing child restraint can be seriously injured or killed if the passenger frontal airbag inflates and the passenger seat is in a forward position. Even if the passenger sensing system has turned off the passenger frontal airbag, no system is fail-safe. No one can guarantee that an airbag will not deploy under some unusual circumstance, even though the airbag is turned off. Never put a rear-facing child restraint in the front seat, even if the airbag is off. If securing a forward-facing child restraint in (Continued) Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Seats and Restraints Warning (Continued) the front outboard passenger seat, always move the seat as far back as it will go. It is better to secure child restraints in the rear seat. Consider using another vehicle to transport the child when a rear seat is not available. The passenger sensing system is designed to turn off the front outboard passenger frontal airbag if: . The front outboard passenger seat is unoccupied. . The system determines an infant is present in a child restraint. . A front outboard passenger takes his/her weight off of the seat for a period of time. . There is a critical problem with the airbag system or the passenger sensing system. When the passenger sensing system has turned off the front outboard passenger frontal airbag, the OFF indicator will light and stay lit as a reminder that the airbag is off. See Passenger Airbag Status Indicator 0 119. The passenger sensing system is designed to turn on the front outboard passenger frontal airbag anytime the system senses that a person of adult size is sitting properly in the front outboard passenger seat. When the passenger sensing system has allowed the airbag to be enabled, the ON indicator will light and stay lit as a reminder that the airbag is active. www.carobook.com For some children, including children in child restraints, and for very small adults, the passenger sensing system may or may not turn off the front outboard passenger frontal airbag, depending upon the person's seating posture and body build. Everyone in the vehicle who has outgrown child restraints should wear a seat belt properly — whether or not there is an airbag for that person. 67 { Warning If the airbag readiness light ever comes on and stays on, it means that something may be wrong with the airbag system. To help avoid injury to yourself or others, have the vehicle serviced right away. See Airbag Readiness Light 0 119 for more information, including important safety information. If the On Indicator Is Lit for a Child Restraint The passenger sensing system is designed to turn off the front outboard passenger frontal airbag if the system determines that an infant is present in a child restraint. If a child restraint has been installed and the ON indicator is lit: 1. Turn the vehicle off. 2. Remove the child restraint from the vehicle. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 68 Seats and Restraints 3. Remove any additional items from the seat such as blankets, cushions, seat covers, seat heaters, or seat massagers. 4. Reinstall the child restraint following the directions provided by the child restraint manufacturer and refer to Securing Child Restraints (With the Seat Belts in the Rear Seat) 0 85 or Securing Child Restraints (With the Seat Belts in the Front Seat) 0 87. Make sure the seat belt retractor is locked by pulling the shoulder belt all the way out of the retractor when installing the child restraint, even if the child restraint is equipped with a seat belt lock off. When the retractor lock is set, the belt can be tightened but not pulled out of the retractor. 5. If, after reinstalling the child restraint and restarting the vehicle, the ON indicator is still lit, turn the vehicle off. Then slightly recline the vehicle seatback and adjust the seat cushion, if adjustable, to make sure that the vehicle seatback is not pushing the child restraint into the seat cushion. If the Off Indicator Is Lit for an Adult-Sized Occupant Also make sure the child restraint is not trapped under the vehicle head restraint. If this happens, adjust the head restraint. See Head Restraints 0 40. 6. Restart the vehicle. www.carobook.com The passenger sensing system may or may not turn off the airbag for a child in a child restraint depending upon the child’s size. It is better to secure the child restraint in a rear seat. Never put a rear-facing child restraint in the front seat, even if the ON indicator is not lit. If a person of adult size is sitting in the front outboard passenger seat, but the OFF indicator is lit, it could be because that person is not sitting properly in the seat or that the child restraint locking feature is engaged. Use the following steps to allow the system to detect that person and enable the front outboard passenger frontal airbag: 1. Turn the vehicle off. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Seats and Restraints 2. Remove any additional material from the seat, such as blankets, cushions, seat covers, seat heaters, or seat massagers. 3. Place the seatback in the fully upright position. 4. Have the person sit upright in the seat, centered on the seat cushion, with legs comfortably extended. 5. If the shoulder portion of the belt is pulled out all the way, the child restraint locking feature will be engaged. This may unintentionally cause the passenger sensing system to turn the airbag off for some adult-sized occupants. If this happens, unbuckle the belt, let the belt go back all the way, and then buckle the belt again without pulling the belt out all the way. { Warning If the front outboard passenger airbag is turned off for an adult-sized occupant, the airbag will not be able to inflate and help protect that person in a crash, resulting in an increased risk of serious injury or even death. An adult-sized occupant should not ride in the front outboard passenger seat, if the passenger airbag OFF indicator is lit. www.carobook.com 6. Restart the vehicle and have the person remain in this position for two to three minutes after the ON indicator is lit. Additional Factors Affecting System Operation Seat belts help keep the passenger in position on the seat during vehicle maneuvers and braking, which helps the passenger sensing system maintain the passenger airbag status. See “Seat Belts” and “Child Restraints” in the Index for additional information about the importance of proper restraint use. 69 A thick layer of additional material, such as a blanket or cushion, or aftermarket equipment such as seat covers, seat heaters, and seat massagers can affect how well the passenger sensing system operates. We recommend that you not use seat covers or other aftermarket equipment except when approved by GM for your specific vehicle. See Adding Equipment to the Airbag-Equipped Vehicle 0 70 for more information about modifications that can affect how the system operates. The ON indicator may be lit if an object, such as a briefcase, handbag, grocery bag, laptop, or other electronic device, is put on an unoccupied seat.

Sit all the way back on the seat. Do the knees bend at the seat edge? If yes, continue. If no, return to the booster seat. Buckle the lap-shoulder belt. Does the shoulder belt rest on the shoulder? If yes, continue. If no, try using the rear seat belt comfort guide, if available. See “Rear Seat Belt Comfort Guides” under Lap-Shoulder Belt 0 55. If a comfort guide is not available, or if the shoulder belt still does not rest on the shoulder, then return to the booster seat. Q: What is the proper way to wear seat belts? 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. www.carobook.com Older children who have outgrown booster seats should wear the vehicle’s seat belts. The manufacturer instructions that come with the booster seat state the weight and height limitations for that booster. Use a booster seat with a lap-shoulder belt until the child passes the fit test below: . 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. Also see “Rear Seat Belt Comfort Guides” under Lap-Shoulder Belt 0 55. According to accident statistics, children are safer when properly restrained in a rear seating position. In a crash, children who are not buckled up can strike other people who are buckled up, or can be thrown out of the vehicle. Older children need to use seat belts properly. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Seats and Restraints { Warning { 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. Never allow a child to wear the seat belt with the shoulder belt 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. www.carobook.com 73 Infants and Young Children Everyone in a vehicle needs protection! This includes infants and all other children. Neither the distance traveled nor the age and size of the traveler changes the need, for everyone, to use safety restraints. In fact, the law in every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 74 Seats and Restraints { Warning Children can be seriously injured or strangled if a shoulder belt is wrapped around their neck. The shoulder belt can tighten but cannot be loosened if it is locked. The shoulder belt locks when it is pulled all the way out of the retractor. It unlocks when the shoulder belt is allowed to go all the way back into the retractor, but it cannot do this if it is wrapped around a child’s neck. If the shoulder belt is locked and tightened around a child’s neck, the only way to loosen the belt is to cut it. Never leave children unattended in a vehicle and never allow children to play with the seat belts. Every time infants and young children ride in vehicles, they should have the protection provided by appropriate child restraints. Neither the vehicle's seat belt system nor its airbag system is designed for them. Children who are not restrained properly can strike other people, or can be thrown out of the vehicle. { Warning Never hold an infant or a child while riding in a vehicle. Due to crash forces, an infant or a child will become so heavy it is not possible to hold it during a crash. 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 www.carobook.com 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. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 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. If it is, the child restraint will have a label saying that it meets federal motor vehicle safety standards. 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. 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. www.carobook.com { 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. 75 { Warning A young child's hip bones are still so small that the vehicle seat belt may not remain low on the hip bones, as it should. Instead, it may settle up around the child's abdomen. In a crash, the belt would apply force on a body area that is unprotected by any bony structure. This alone could cause serious or fatal injuries. To reduce the risk of serious or fatal injuries during a crash, young children should always be secured in an appropriate child restraint. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 76 Seats and Restraints Child Restraint Systems Forward-Facing Child Restraint Rear-Facing Infant Restraint A rear-facing child restraint provides restraint with the seating surface against the back of the infant. The harness system holds the infant in place and, in a crash, acts to keep the infant positioned in the restraint. Booster Seats www.carobook.com A forward-facing child restraint provides restraint for the child's body with the harness. A belt-positioning booster seat is used for children who have outgrown their forward-facing child restraint. Boosters are designed to improve the fit of the vehicle's seat belt system until the child is large enough for the vehicle seat belts to fit properly without a booster seat. See the seat belt fit test in Older Children 0 72. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Seats and Restraints Securing an Add-On Child Restraint in the Vehicle { Warning A child can be seriously injured or killed in a crash if the child restraint is not properly secured in the vehicle. Secure the child restraint properly in the vehicle using the vehicle seat belt or LATCH system, following the instructions that came with that child restraint and the instructions in this manual. To help reduce the chance of injury, the child restraint must be secured in the vehicle. Child restraints must be secured in vehicle seats by lap belts or the lap belt portion of a lap-shoulder belt, or by the LATCH system. See Lower Anchors and Tethers for Children (LATCH System) 0 79 for more information. Children can be endangered in a crash if the child restraint is not properly secured in the vehicle. When securing an add-on child restraint, refer to the following: 1. Instruction labels provided on the child restraint 2. Instruction manual provided with the child restraint 77 availability in Canada, check with Transport Canada or the Provincial Ministry of Transportation office. Securing the Child Within the Child Restraint 3. This vehicle owner's manual { Warning The child restraint instructions are important, so if they are not available, obtain a replacement copy from the manufacturer. A child can be seriously injured or killed in a crash if the child is not properly secured in the child restraint. Secure the child properly following the instructions that came with that child restraint. Keep in mind that an unsecured child restraint can move around in a collision or sudden stop and injure people in the vehicle. Be sure to properly secure any child restraint in the vehicle — even when no child is in it. www.carobook.com In some areas Certified Child Passenger Safety Technicians (CPSTs) are available to inspect and demonstrate how to correctly use and install child restraints. In the U.S., refer to the National Highway Traffic Safety Administration (NHTSA) website to locate the nearest child safety seat inspection station. For CPST Where to Put the Restraint According to accident statistics, children and infants are safer when properly restrained in an appropriate child restraint secured in a rear seating position. Whenever possible, children aged 12 and under should be secured in a rear seating position. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 78 Seats and Restraints Never put a rear-facing child restraint in the front. This is because the risk to the rear-facing child is so great if the airbag deploys. { Warning A child in a rear-facing child restraint can be seriously injured or killed if the front passenger airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag. A child in a forward-facing child restraint can be seriously injured or killed if the front passenger airbag inflates and the passenger seat is in a forward position. Even if the passenger sensing system has turned off the front passenger frontal airbag, no system is fail-safe. No one can guarantee that an airbag will not deploy under some unusual circumstance, even though it is turned off. (Continued) 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 seat, always move the front passenger seat as far back as it will go. It is better to secure the child restraint in a rear seat. See Passenger Sensing System 0 66 for additional information. Depending on where you place the child restraint and the size of the child restraint, you may not be able to access adjacent seat belts or LATCH anchors for additional passengers or child restraints. Adjacent seating positions should not be used if the child restraint prevents access to or interferes with the routing of the seat belt. Wherever a child restraint is installed, be sure to follow the instructions that came with the child restraint and secure the child restraint properly. www.carobook.com When securing a child restraint with the seat belts in a rear seat position, study the instructions that came with the child restraint to make sure it is compatible with this vehicle. Child restraints and booster seats vary considerably in size, and some may fit in certain seating positions better than others. Keep in mind that an unsecured child restraint can move around in a collision or sudden stop and injure people in the vehicle. Be sure to properly secure any child restraint in the vehicle — even when no child is in it. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Seats and Restraints Lower Anchors and Tethers for Children (LATCH System) Booster seats use the vehicle’s seat belts to secure the child and the booster seat. If the manufacturer recommends that the booster seat be secured with the LATCH system, this can be done as long as the booster seat can be positioned properly and there is no interference with the proper positioning of the lap-shoulder belt on the child. The LATCH system secures a child restraint during driving or in a crash. LATCH attachments on the child restraint are used to attach the child restraint to the anchors in the vehicle. This system is designed to make installation of a child restraint easier. In order to use the LATCH system in your vehicle, you need a child restraint that has LATCH attachments. LATCH-compatible rear-facing and forward-facing child seats can be properly installed using either the LATCH anchors or the vehicle’s seat belts. Do not use both the seat belts and the LATCH anchorage system to secure a rear-facing or forward-facing child seat. Make sure to follow the instructions that came with the child restraint, and also the instructions in this manual. www.carobook.com When installing a child restraint with a top tether, you must also use either the lower anchors or the seat belts to properly secure the child restraint. A child restraint must never be installed using only the top tether and anchor. 79 For a forward-facing 5-pt harness child restraint where the combined weight of the child and restraint are up to 29.5 kg (65 lb), use either the lower LATCH anchorages with the top tether anchorage, or the seat belt with the top tether anchorage. Where the combined weight of the child and restraint are greater than 29.5 kg (65 lb), use the seat belt with the top tether anchorage only. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 80 Seats and Restraints Recommended Methods for Attaching Child Restraints Restraint Type Combined Weight of the Child + Child Restraint Rear-Facing Child Restraint Up to 29.5 kg (65 lb) Rear-Facing Child Restraint Greater than 29.5 kg (65 lb) Forward-Facing Child Restraint Up to 29.5 kg (65 lb) Forward-Facing Child Restraint Greater than 29.5 kg (65 lb) See Securing Child Restraints (With the Seat Belts in the Rear Seat) 0 85 or Securing Child Restraints (With the Seat Belts in the Front Seat) 0 87.

Others require the top tether always to be attached. In Canada, the law requires that forward-facing child restraints have a top tether, and that the tether be attached. Be sure to read and follow the instructions for your child restraint. Lower Anchor and Top Tether Anchor Locations Lower anchors (1) are metal bars built into the vehicle. There are two lower anchors for each LATCH seating position that will accommodate a child restraint with lower attachments (2). www.carobook.com A top tether (3, 4) is used to secure the top of the child restraint to the vehicle. A top tether anchor is built into the vehicle. The top tether attachment hook (2) on the child restraint connects to the top tether anchor in the vehicle in order to reduce the forward movement and rotation of the child restraint during driving or in a crash. The child restraint may have a single tether (3) or a dual tether (4). Either will have a single attachment hook (2) to secure the top tether to the anchor. Rear Seat I : Seating positions with top tether anchors. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 82 Seats and Restraints H : Seating positions with two lower anchors. To assist in locating the lower anchors, each seating position with lower anchors has two labels, near the crease between the seatback and the seat cushion.

Do not use the Universal Remote system with any garage door opener that does not have the stop and reverse feature. This includes any garage door opener model manufactured before April 1, 1982. Read these instructions completely before programming the Universal Remote system. It may help to have another person assist with the programming process. Keep the original hand-held transmitter for use in other vehicles as well as for future programming. Erase the programming when vehicle ownership is terminated. See “Erasing Universal Remote System Buttons” later in this section. To program a garage door opener, park outside directly in line with and facing the garage door opener receiver. Clear all people and objects near the garage door. Make sure the hand-held transmitter has a new battery for quicker and more accurate transmission of the radio-frequency signal. Programming the Universal Remote System For questions or programming help, see www.homelink.com/gm or call 1-800-355-3515. For calls placed outside the U.S., Canada, or Puerto Rico, international rates will apply and may differ based on landline or mobile phone. www.carobook.com Programming involves time-sensitive actions, and may time out causing the procedure to be repeated. To program up to three devices: 1. Hold the end of the hand-held transmitter about 3 to 8 cm (1 to 3 in) away from the Universal Remote system buttons with the indicator light in view. The hand-held transmitter was supplied by the manufacturer of the garage door opener receiver. 2. At the same time, press and hold both the hand-held transmitter button and one of the three Universal Remote system buttons to be used to operate the garage door. Do not release either button until the indicator light changes from a slow to a rapid flash. Then release both buttons. Some garage door openers may require substitution of Step 2 with the procedure under “Radio Signals for Some Gate Operators” later in this section. 3. Press and hold the newly programmed Universal Remote system button for five seconds while watching the indicator light and garage door activation. . If the indicator light stays on continuously or the garage door moves when the button is pressed, then programming is complete. There is no need to complete Steps 4–6. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Instruments and Controls . . 143 If the indicator light does not come on or the garage door does not move, a second button press may be required. For a second time, press and hold the newly programmed button for five seconds. If the light stays on or the garage door moves, programming is complete. 4. After completing Steps 1–3, locate the Learn or Smart button inside the garage on the garage door opener receiver. The name and color of the button may vary by manufacturer. The Universal Remote system should now activate the garage door. 5. Press and release the Learn or Smart button. Step 6 must be completed within 30 seconds of pressing this button.

Battery Load Management The vehicle has Electric Power Management (EPM) that estimates the battery's temperature and state of charge. It then adjusts the voltage for best performance and extended life of the battery. When the battery's state of charge is low, the voltage is raised slightly to quickly bring the charge back up. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. If the vehicle has a voltmeter gauge or a voltage display on the Driver Information Center (DIC), you may see the voltage move up or down. This is normal. If there is a problem, an alert will be displayed. The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles. This is because the generator (alternator) may not be spinning fast enough at idle to produce all of the power needed for very high electrical loads. A high electrical load occurs when several of the following are on, such as: headlamps, high beams, rear window defogger, climate control fan at high speed, heated seats, engine cooling fans, trailer loads, and loads plugged into accessory power outlets. Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest levels of corrective action, this action may be noticeable to the driver. If so, a DIC battery voltage and charging message displays. It is recommended that the driver reduce the electrical loads as much as possible. See Driver Information Center (DIC) (Base and Midlevel) 0 129 or Driver Information Center (DIC) (Uplevel) 0 133. www.carobook.comBattery Power Protection EPM works to prevent excessive discharge of the battery. It does this by balancing the generator's output and the vehicle's electrical needs. It can increase engine idle speed to generate more power whenever needed. It can temporarily reduce the power demands of some accessories. This feature helps prevent the battery from being drained, if the interior courtesy lamps or reading lamps are accidentally left on.

Braking Braking action involves perception time and reaction time. Deciding to push the brake pedal is perception time. Actually doing it is reaction time. Average driver reaction time is about three-quarters of a second. In that time, a vehicle moving at 100 km/h (60 mph) travels 20 m (66 ft), which could be a lot of distance in an emergency. Helpful braking tips to keep in mind include: . Keep enough distance between you and the vehicle in front of you. . Avoid needless heavy braking. . Keep pace with traffic. If the engine ever stops 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. Steering The vehicle has electric power steering. It does not have power steering fluid. Regular maintenance is not required. www.carobook.com Electric Power Steering Caution To avoid damage to the steering system, do not drive over curbs, parking barriers, or similar objects at speeds greater than 3 km/h (1 mph). Use care when driving over other objects such as lane dividers and speed bumps. Damage caused by misuse of the vehicle is not covered by the vehicle warranty. If power steering assist is lost due to a system malfunction, the vehicle can be steered, but may require increased effort. If the steering assist is used for an extended period of time while the vehicle is not moving, power assist may be reduced. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Driving and Operating If the steering wheel is turned until it reaches the end of its travel and is held against that position for an extended period of time, power steering assist may be reduced. Normal use of the power steering assist should return when the system cools down. See your dealer if there is a problem. . 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. Off-Road Recovery Take curves at a reasonable speed. . Reduce speed before entering a curve. . Maintain a reasonable steady speed through the curve. . Wait until the vehicle is out of the curve before accelerating gently into the straightaway. Steering in Emergencies . There are some situations when steering around a problem may be more effective than braking. 1. Ease off the accelerator and then, if there is nothing in the way, steer the vehicle so that it straddles the edge of the pavement. 2. Turn the steering wheel about one-eighth of a turn, until the right front tire contacts the pavement edge. 3. Turn the steering wheel to go straight down the roadway. Curve Tips . 165 www.carobook.com The vehicle's right wheels can drop off the edge of a road onto the shoulder while driving. Follow these tips: Loss of Control Skidding There are three types of skids that correspond to the vehicle's three control systems: . Braking Skid — wheels are not rolling. . Steering or Cornering Skid — too much speed or steering in a curve causes tires to slip and lose cornering force. . Acceleration Skid — too much throttle causes the driving wheels to spin. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 166 Driving and Operating Defensive drivers avoid most skids by taking reasonable care suited to existing conditions, and by not overdriving those conditions. But skids are always possible. If the vehicle starts to slide, follow these suggestions: . Ease your foot off the accelerator pedal and steer the way you want the vehicle to go. The vehicle may straighten out. Be ready for a second skid if it occurs. . Slow down and adjust your driving according to weather conditions. Stopping distance can be longer and vehicle control can be affected when traction is reduced by water, snow, ice, gravel, or other material on the road. Learn to recognize warning clues — such as enough water, ice, or packed snow on the road to make a mirrored surface — and slow down when you have any doubt. . Try to avoid sudden steering, acceleration, or braking, including reducing vehicle speed by shifting to a lower gear. Any sudden changes could cause the tires to slide. Warning (Continued) position. This could cause you to lose control and crash. You and your passengers should always wear seat belts. 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) tires must not be driven off-road except on a level, solid surface. To contact the tire manufacturer for more information about the original equipment tires, see the warranty manual. Before Driving Off-Road . Have all necessary maintenance and service work completed. . Fuel the vehicle, fill fluid levels, and check inflation pressure in all tires, including the spare, if equipped. www.carobook.com 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 (Continued) . 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 air dam reduces fuel economy. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Driving and Operating Caution Warning (Continued) heaviest things should be on the floor, forward of the rear axle. 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 (Continued) Heavy loads on the roof raise the vehicle's center of gravity, making it more likely to roll over. You can be seriously or fatally injured if the vehicle rolls over. Put heavy loads inside the cargo area, not on the roof. www.carobook.com For more information about loading the vehicle, see Vehicle Load Limits 0 174. 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. . 167 Do not park over things that burn. See Parking over Things That Burn 0 185. Driving on Hills Driving safely on hills requires good judgment and an understanding of what the vehicle can and cannot do. { Warning Many hills are simply too steep for any vehicle. Driving up hills can cause the vehicle to stall. Driving down hills can cause loss of control. Driving across hills can cause a rollover. You could be injured or killed. Do not drive on steep hills. Before driving on a hill, assess the steepness, traction, and obstructions. If the terrain ahead cannot be seen, get out of the vehicle and walk the hill before driving further. When driving on hills: Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 168 Driving and Operating . Use a low gear and keep a firm grip on the steering wheel. . Maintain a slow speed. . When possible, drive straight up or down the hill. . Slow down when approaching the top of the hill. . Use headlamps even during the day to make the vehicle more visible. { Warning Driving to the top of a hill at high speed can cause a crash. There could be a drop-off, embankment, cliff, or even another vehicle. You could be seriously injured or killed. As you near the top of a hill, slow down and stay alert. . Never go downhill forward or backward with 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. { 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. www.carobook.com 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 back straight down. . Never try to turn the vehicle around. If the hill is steep enough to stall the vehicle, it is steep enough to cause it to roll over. . If you cannot make it up the hill, back straight down the hill. . Never back down a hill in N (Neutral) using only the brake. . The vehicle can roll backward quickly and you could lose control. . If driving downhill when the vehicle stalls, shift to a lower gear, release the parking brake, and drive straight down the hill. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Driving and Operating . 3. If the vehicle cannot be restarted after stalling, set the parking brake, shift into P (Park), and turn the vehicle off. 3.1. Leave the vehicle and seek help. . 3.2. Stay clear of the path the vehicle would take if it rolled downhill. . Avoid turns that take the vehicle across the incline of the hill. A hill that can be driven straight up or down might be too steep to drive across. Driving across an incline puts more weight on the downhill wheels which could cause a downhill slide or a rollover. 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. Driving in Mud, Sand, Snow, or Ice If an incline must be driven across, and the vehicle starts to slide, turn downhill. This should help straighten out the vehicle and prevent the side slipping. Traction changes when driving on sand. On loose sand, such as on beaches or sand dunes, the tires tend to sink into the sand. This affects steering, accelerating, and braking. Drive at a reduced speed and avoid sharp turns or abrupt maneuvers. { Warning www.carobook.com . Surface conditions can be a problem. Loose gravel, muddy spots, or even wet grass can cause the tires to slip sideways, downhill. If the vehicle slips sideways, it can hit something that will trip it — a rock, a rut, etc. — and roll over. 169 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. 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 is reduced on hard packed snow and ice and it is easy to lose control. Reduce vehicle speed when driving on hard packed snow and ice. { Warning Driving on frozen lakes, ponds, or rivers can be dangerous. Ice conditions vary greatly and the vehicle could fall through the ice; (Continued) Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 170 Driving and Operating Warning (Continued) Caution you and your passengers could drown. Drive your vehicle on safe surfaces only. 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. 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 tires. Traction could be lost, and the vehicle could roll over. Do not drive through rushing water. 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 0 170. 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, tires, 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 0 339. on Wet Roads www.carobook.comDriving Rain and wet roads can reduce After Off-Road Driving Remove any brush or debris that has collected on the underbody or chassis, or under the hood. These accumulations can be a fire hazard. 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. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Driving and Operating wet enough and you are going fast enough. When the vehicle is hydroplaning, it has little or no contact with the road. { 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. There is no hard and fast rule about hydroplaning. The best advice is to slow down when the road is wet. Other Rainy Weather Tips 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. Besides slowing down, other wet weather driving tips include: . Allow extra following distance. . Pass with caution. www.carobook.com . Keep windshield wiping Hydroplaning Hydroplaning is dangerous. Water can build up under the vehicle's tires so they actually ride on the water. This can happen if the road is equipment in good shape. . Keep the windshield washer fluid reservoir filled. . Have good tires with proper tread depth. See Tires 0 284. . Turn off cruise control. . Activate All-Wheel Drive (AWD) mode. See Driver Mode Control 0 196. 171 Hill and Mountain Roads Driving on steep hills or through mountains is different than driving on flat or rolling terrain. Tips include: . Keep the vehicle serviced and in good shape. . Check all fluid levels and brakes, tires, cooling system, and transmission. . Shift to a lower gear when going down steep or long hills. { Warning Using the brakes to slow the vehicle on a long downhill slope can cause brake overheating, can reduce brake performance, and could result in a loss of braking. Shift the transmission to a lower gear to let the engine assist the brakes on a steep downhill slope. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 172 Driving and Operating { Warning Coasting downhill in N (Neutral) or with the ignition off is dangerous. This can cause overheating of the brakes and loss of steering assist. Always have the engine running and the vehicle in gear. . Drive at speeds that keep the vehicle in its own lane. Do not swing wide or cross the center line. . Be alert on top of hills; something could be in your lane (e.g., stalled car, crash). . Pay attention to special road signs (e.g., falling rocks area, winding roads, long grades, passing or no-passing zones) and take appropriate action. clear roads in shaded areas. The surface of a curve or an overpass can remain icy when the surrounding roads are clear. Avoid sudden steering maneuvers and braking while on ice. Winter Driving Driving on Snow or Ice Snow or ice between the tires and the road creates less traction or grip, so drive carefully. Wet ice can occur at about 0 °C (32 °F) when freezing rain begins to fall. Avoid driving on wet ice or in freezing rain until roads can be treated. For Slippery Road Driving: . Accelerate gently. Accelerating too quickly causes the wheels to spin and makes the surface under the tires slick. . Turn on Traction Control. See Traction Control/Electronic Stability Control 0 194. . The Antilock Brake System (ABS) improves vehicle stability during hard stops, but the brakes should be applied sooner than when on dry pavement. See Antilock Brake System (ABS) 0 191. . Allow greater following distance and watch for slippery spots. Icy patches can occur on otherwise . 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 0 196 and All-Wheel Drive 0 191. www.carobook.com Blizzard Conditions Stop the vehicle in a safe place and signal for help. Stay with the vehicle unless there is help nearby. If possible, use Roadside Assistance. See Roadside Assistance Program 0 359. To get help and keep everyone in the vehicle safe: . Turn on the hazard warning flashers. . Tie a red cloth to an outside mirror. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Driving and Operating { Warning Snow can trap engine exhaust under the vehicle. This may cause exhaust gases to get inside. Engine exhaust contains carbon monoxide (CO), which cannot be seen or smelled. It can cause unconsciousness and even death. If the vehicle is stuck in snow: . Clear snow from the base of the vehicle, especially any blocking the exhaust pipe. . 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 (Continued) Warning (Continued) 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. www.carobook.com 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 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. 173 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 0 194. { Warning If the vehicle's tires spin at high speed, they can explode, and you or others could be injured. The vehicle can overheat, causing an engine compartment fire or other damage. Spin the wheels as little as possible and avoid going above 56 km/h (35 mph). Select All-Wheel Drive (AWD) Mode. See Driver Mode Control 0 196 and All-Wheel Drive 0 191. 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 Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 174 Driving and Operating between R (Reverse) and a low forward gear, spinning the wheels as little as possible. To prevent transmission wear, wait until the wheels stop spinning before shifting gears. Release the accelerator pedal while shifting, and press lightly on the accelerator pedal when the transmission is in gear. Slowly spinning the wheels in the forward and reverse directions causes a rocking motion that could free the vehicle. If that does not get the vehicle out after a few tries, it might need to be towed out. If the vehicle does need to be towed out, see Towing the Vehicle 0 323. Vehicle Load Limits It is very important to know how much weight the vehicle can carry. This weight is called the vehicle capacity weight and includes the weight of all occupants, cargo, and all nonfactory-installed options. Two labels on the vehicle may show how much weight it may properly carry, the Tire and Loading Information label and the Certification/Tire label. Tire and Loading Information Label { Warning Do not load the vehicle any heavier than the Gross Vehicle Weight Rating (GVWR), or either the maximum front or rear Gross Axle Weight Rating (GAWR). This can cause systems to break and change the way the vehicle handles. This could cause loss of control and a crash. Overloading can also reduce stopping distance, damage the tires, and shorten the life of the vehicle. www.carobook.com Example Label A vehicle-specific Tire and Loading Information label is attached to the center pillar (B-pillar). The tire and loading information label shows the number of occupant seating positions (1), and the maximum vehicle capacity weight (2) in kilograms and pounds. The Tire and Loading Information label also shows the size of the original equipment Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Driving and Operating tires (3) and the recommended cold tire inflation pressures (4). For more information on tires and inflation see Tires 0 284 and Tire Pressure 0 291. There is also important loading information on the vehicle Certification/Tire label. It may show the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for the front and rear axle. See “Certification/Tire Label” later in this section. 2. Determine the combined weight of the driver and passengers that will be riding in your vehicle. 3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs. 4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the "XXX" amount equals 1400 lbs. and there will be five 150 lb passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs. (1400-750 (5 x 150) = 650 lbs.) www.carobook.com “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. 5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely 175 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 0 233 for important information on towing a trailer, towing safety rules and trailering tips. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 176 Driving and Operating Example 1 1.

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. If parking on a hill and pulling a trailer, see Driving Characteristics and Towing Tips 0 229. www.carobook.com P : This position locks the drive wheels. Use P (Park) when starting the engine because the vehicle cannot move easily. { Warning It is dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll. (Continued) Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 188 Driving and Operating Warning (Continued) Do not leave the vehicle when the engine is running. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move, even when you are on fairly level ground, always set the parking brake and move the shift lever to P (Park). See Shifting Into Park 0 184 and Driving Characteristics and Towing Tips 0 229. Make sure the shift lever is fully in P (Park) before starting the engine. The vehicle has an automatic transmission shift lock control system. With the ignition on, fully apply the regular brake, then press the button on the shift lever before shifting from P (Park). If you cannot shift out of P (Park), ease pressure on the shift lever, then push the shift lever all the way into P (Park) as you maintain brake application. Then press the shift lever button and move the shift lever into another gear. See Shifting out of Park 0 185. R : Use this gear to back up. Caution Shifting to R (Reverse) while the vehicle is moving forward could damage the transmission. The repairs would not be covered by the vehicle warranty. Shift to R (Reverse) only after the vehicle is stopped. www.carobook.com To rock the vehicle back and forth to get out of snow, ice, or sand without damaging the transmission, see If the Vehicle Is Stuck 0 173. N : In this position, the engine does not connect with the wheels. To restart the engine when the vehicle is already moving, use N (Neutral) only. { Warning Shifting into a drive gear while the engine is running at high speed is dangerous. Unless your foot is firmly on the brake pedal, the vehicle could move very rapidly. You could lose control and hit people or objects. Do not shift into a drive gear while the engine is running at high speed. Caution Shifting out of P (Park) or N (Neutral) with the engine running at high speed may damage the transmission. The repairs would not be covered by the vehicle warranty. Be sure the engine is not running at high speed when shifting the vehicle. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Driving and Operating Caution A transmission hot message may display if the automatic transmission fluid is too hot. Driving under this condition can damage the vehicle. Stop and idle the engine to cool the automatic transmission fluid. This message clears when the transmission fluid has cooled sufficiently. D : This position is for normal driving. If more power is needed for passing, press the accelerator pedal down. Caution If the vehicle does not shift gears, the transmission could be damaged. Have the vehicle serviced right away. If the vehicle is stopped on a hill, with your foot off the brake pedal, the vehicle may roll. This is normal and is due to the torque converter 189 designed to improve fuel economy and performance. Use the brake to hold the vehicle on a hill. Do not use the accelerator pedal. Manual Mode If equipped with the 2.0L L4 engine, engine speeds may be increased while driving at highway speeds while the engine is still warming up. ERS mode allows you to choose the top-gear limit of the transmission and the vehicle's speed while driving downhill or towing a trailer. The vehicle has an electronic shift position indicator within the instrument cluster. When using the ERS mode a number will display next to the L, indicating the highest gear available for the range selected. L : This position gives you access to gear ranges. This provides more engine braking but lower fuel economy than D (Drive). You can use it on very steep hills, or in deep snow or mud. See Manual Mode 0 189. www.carobook.com Operating Modes : The transmission may operate in a lower gear than normal to improve vehicle performance. The engine speed may be higher and there may be an increase in noise during the following conditions: . When climbing a grade . When driving downhill . When driving in hot temperatures, or at high altitude Electronic Range Select (ERS) Mode Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 190 Driving and Operating To use this feature: 1. Press the shift lever button and move the shift lever to L (Low). 2. Press + (Plus) or − (Minus) on the shift lever to increase or decrease the gear range available. When you shift from D (Drive) to L (Low), the transmission will shift to a pre-determined lower gear range. The highest gear available for this pre-determined range is displayed next to the L in the DIC. See Driver Information Center (DIC) (Base and Midlevel) 0 129 or Driver Information Center (DIC) (Uplevel) 0 133. The number displayed in the DIC is the highest gear that the transmission will be allowed to operate in. This means that all gears below that number are available. For example, when 4 (Fourth) is shown next to the L, 1 (First) through 4 (Fourth) gears are automatically shifted by the vehicle. The transmission will not shift into 5 (Fifth) until the + (Plus) button is used or you shift back into D (Drive). If the transmission is in 9 (ninth) gear when L (low) is selected, a downshift to 7 (seventh) will be commanded. If in 8 (eighth) through 2 (second), a single downshift will occur. While in L (Low), the transmission will prevent shifting to a lower gear range if the engine speed is too high. You have a brief period of time to slow the vehicle. If vehicle speed is not reduced within the time allowed, the lower gear range shift will not be completed. You must further slow the vehicle, then press − (Minus) to the desired lower gear range. Automatic Engine Grade Braking is not available when the ERS is active. It is available in D (Drive) for both normal driving and Tow/Haul Mode. While using the ERS, cruise control and the Tow/Haul Mode can be used. See “Tow/Haul Mode” following. Tow/Haul Mode This feature can assist when towing or hauling a heavy load. See Driver Mode Control 0 196 to activate Tow/ Haul Mode. www.carobook.com Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Driving and Operating Drive Systems See Driver Mode Control 0 196. Brakes All-Wheel Drive When operated in two-wheel drive, the vehicle will deliver power to the front wheels only and may provide better fuel economy. Electric Brake Boost Vehicles with this feature can operate in All-Wheel Drive (AWD) Mode. When using a compact spare tire on an AWD vehicle, the system automatically detects the compact spare and reduces AWD performance to protect the system. To restore full AWD operation and prevent excessive wear on the system, replace the compact spare with a full-size tire as soon as possible. See Compact Spare Tire 0 320. www.carobook.com Turn the knob to 4 to select AWD. 191 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 shutdown. Noise may be heard during this time. If the brake pedal is pressed 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. ABS performs a system check when the vehicle is first driven. A momentary motor or clicking noise Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 192 Driving and Operating may be heard while this test is going on, and the brake pedal may move slightly. This is normal. Using ABS Do not pump the brakes. Just hold the brake pedal down firmly. Hearing or feeling ABS operate is normal. Braking in Emergencies If there is a problem with ABS, this warning light stays on. See Antilock Brake System (ABS) Warning Light 0 123. ABS does not change the time needed to get a foot on the brake pedal and does not always decrease stopping distance. If you get too close to the vehicle ahead, there will not be enough time to apply the brakes if that vehicle suddenly slows or stops. Always leave enough room ahead to stop, even with ABS. ABS allows steering and braking at the same time. In many emergencies, steering can help even more than braking. Electric Parking Brake off. To prevent draining the battery, avoid repeated cycles of the EPB system when the engine is not running. The system has a Y, PARK, or f Electric Parking Brake light, and some vehicles may have a 8 Service Parking Brake light. See Electric Parking Brake Light 0 123 and Service Electric Parking Brake Light 0 123. Before leaving the vehicle, check for Electric Parking Brake light to www.carobook.comthe ensure that the EPB 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 vehicle has an Electric Parking Brake (EPB). The EPB can always be activated, even if the ignition is The Electric Parking Brake light will flash and then stay on once the EPB is fully applied. If the light flashes continuously, then the EPB is only partially applied, the vehicle is in Service Mode, or there is a Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Driving and Operating problem with the EPB. A Driver Information Center (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 Electric Parking Brake light is flashing. See your dealer. See Electric Parking Brake Light 0 123. If the Service Parking Brake light is on or the Electric Parking Brake light flashes when the ignition is turned on, press the EPB switch and hold it. Continue to hold the switch until the Electric Parking Brake light remains on. If the Service Parking Brake light remains on, see your dealer. If the EPB is applied while the vehicle is moving, the vehicle will decelerate as long as the switch is pressed. If the switch is pressed until the vehicle comes to a stop, the EPB will remain applied. The vehicle may automatically apply the EPB in some situations when the vehicle is not moving. This is normal, and is done to periodically check the correct operation of the EPB system. If the EPB fails to apply, block the rear wheels to prevent vehicle movement. EPB Release To release the EPB: 1. Turn the ignition on or to ACC/ ACCESSORY. 2. Apply and hold the brake pedal. www.carobook.com 3. Press the EPB switch momentarily. The EPB is released when the Electric Parking Brake light is off. If the Service Parking Brake light is on or the Electric Parking Brake light flashes, release the EPB by pressing and holding the EPB switch. Continue to hold the switch until the Electric Parking Brake light is off. If either light stays on after release is attempted, see your dealer. 193 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 parking on a hill, or if the vehicle is pulling a trailer, see Driving Characteristics and Towing Tips 0 229. 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 Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 194 Driving and Operating activate the Antilock Brake System (ABS) if the brake pedal is not pushed hard enough to activate ABS normally. Minor noise, brake pedal pulsation, and/or pedal movement during this time may occur. Continue to apply the brake pedal as the driving situation dictates. Brake Assist disengages when the brake pedal is released. Hill Start Assist (HSA) { Warning Do not rely on the HSA feature. HSA does not replace the need to pay attention and drive safely. You may not hear or feel alerts or warnings provided by this system. Failure to use proper care when driving may result in injury, death, or vehicle damage. See Defensive Driving 0 163. 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. www.carobook.com TCS activates if it senses that any of the drive wheels are spinning or beginning to lose traction. When this happens, TCS applies the brakes to the spinning wheels and reduces engine power to limit wheel spin. TCS also applies torque to the non-spinning wheel to increase traction and acceleration. StabiliTrak/ESC activates when the vehicle senses a difference between the intended path and the direction the vehicle is actually traveling. StabiliTrak/ESC selectively applies Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Driving and Operating braking pressure to any one of the vehicle wheel brakes to assist the driver in keeping the vehicle on the intended path. If cruise control is being used and TCS 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. See If the Vehicle Is Stuck 0 173 and “Turning the Systems Off and On” later in this section. 195 2. Turn the engine off and wait 15 seconds. 3. Start the engine. 4. Drive the vehicle. The indicator light for both systems is in the instrument cluster. This light will: . Flash when TCS is limiting wheel spin . Flash when StabiliTrak/ESC is activated . Turn on and stay on when either system is not working www.carobook.com If either system fails to turn on or to activate, a message may display in the Driver Information Center (DIC), and d comes on and stays on to indicate that the system is inactive and is not assisting the driver in maintaining control. The vehicle is safe to drive, but driving should be adjusted accordingly. If d comes on and stays on: 1. Stop the vehicle. If d comes on and stays on, the vehicle may need more time to diagnose the problem. If the condition persists, see your dealer. Turning the Systems Off and On Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 196 Driving and Operating Caution Do not repeatedly brake or accelerate heavily when TCS is off.

Front Pedestrian Alert Automatic Braking If FPB detects it is about to crash into a pedestrian directly ahead, and the brakes have not been applied, FPB may automatically brake moderately or brake hard. This can help to avoid some very low speed pedestrian crashes or reduce pedestrian injury. FPB can automatically brake to detected pedestrians between 8 km/h (5 mph) and 80 km/h (50 mph). Automatic Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Driving and Operating braking levels may be reduced under certain conditions, such as higher speeds. If this happens, Automatic Braking may engage the Electric Parking Brake (EPB) to hold the vehicle at a stop. Release the EPB. A firm press of the accelerator pedal will also release Automatic Braking and the EPB. { Warning FPB may alert or automatically brake the vehicle suddenly in situations where it is unexpected and undesired. It could falsely alert or brake for objects similar in shape or size to pedestrians, including shadows. This is normal operation and the vehicle does not need service. To override Automatic Braking, firmly press the accelerator pedal, if it is safe to do so. Automatic Braking can be disabled through vehicle personalization. See “Front Pedestrian Detection” in “Collision/Detection Systems” under Vehicle Personalization 0 137. { Warning Using the Front Pedestrian Braking system while towing a trailer could cause you to lose control of the vehicle and crash. Turn the system to Alert or Off when towing a trailer. www.carobook.com Cleaning the System If FPB does not seem to operate properly, cleaning the outside of the windshield in front of the rearview mirror may correct the issue. Side Blind Zone Alert (SBZA) If equipped, the SBZA system is a lane-changing aid that assists drivers with avoiding crashes that occur with moving vehicles in the side blind zone, or blind spot areas. 221 When the vehicle is in a forward gear, the left or right side mirror display will light up if a moving vehicle is detected in that blind zone. If the turn signal is activated and a vehicle is also detected on the same side, the display will flash as an extra warning not to change lanes. Since this system is part of the Lane Change Alert (LCA) system, read the entire LCA section before using this feature. Lane Change Alert (LCA) If equipped, the LCA system is a lane-changing aid that assists drivers with avoiding lane change crashes that occur with moving vehicles in the side blind zone (or spot) areas or with vehicles rapidly approaching these areas from behind. The LCA warning display will light up in the corresponding outside mirror and will flash if the turn signal is on. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 222 Driving and Operating { Warning LCA does not alert the driver to vehicles outside of the system detection zones, pedestrians, bicyclists, or animals. It may not provide alerts when changing lanes under all driving conditions. Failure to use proper care when changing lanes may result in injury, death, or vehicle damage. Before making a lane change, always check mirrors, glance over your shoulder, and use the turn signals. LCA Detection Zones 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. Left Outside Mirror Display Right Outside Mirror Display When the vehicle is started, both outside mirror LCA displays will briefly come on to indicate the system is operating. When the vehicle is in a forward gear, the left or right outside mirror display will light up if a moving vehicle is detected in the next lane over in that blind zone or rapidly approaching that zone. If the turn signal is activated in the same direction as a detected vehicle, this display will flash as an extra warning not to change lanes. www.carobook.com How the System Works The LCA symbol lights up in the outside mirrors when the system detects a moving vehicle in the next lane over that is in the side blind zone or rapidly approaching that zone from behind. A lit LCA symbol indicates it may be unsafe to change lanes. Before making a lane change, check the LCA display, check mirrors, glance over your shoulder, and use the turn signals. LCA can be disabled through vehicle personalization. When you disable LCA, Side Blind Zone Alert is also disabled. See “Collision/ Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Driving and Operating Detection Systems” under Vehicle Personalization 0 137. If LCA is disabled by the driver, the LCA mirror displays will not light up. When the System Does Not Seem to Work Properly The LCA system requires some driving for the system to calibrate to maximum performance. This calibration may occur more quickly if the vehicle is driving on a straight highway road with traffic and roadside objects (e.g., guardrails, barriers). with the detection of vehicles. This is normal system operation; the vehicle does not need service. system is clean, the system may need service. Take the vehicle to your dealer. LCA may not always alert the driver to vehicles in the next lane over, especially in wet conditions or when driving on sharp curves. The system does not need to be serviced. The system may light up due to guardrails, signs, trees, shrubs, and other non-moving objects. This is normal system operation; the vehicle does not need service. Radio Frequency Information LCA may not operate when the LCA www.carobook.com sensors in the left or right corners of 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 223 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 0 327. If the DIC still displays the system unavailable message after cleaning both sides of the vehicle toward the rear corners of the vehicle, see your dealer. If the LCA displays do not light up when moving vehicles are in the side blind zone or are rapidly approaching this zone and the See Radio Frequency Statement 0 365. 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 between 60 km/h (37 mph) and 180 km/h (112 mph). It 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. LKA can be overridden by turning the steering wheel. This system is not intended to keep the vehicle centered in the lane. LKA will not assist and alert if the turn signal is active in the direction of lane departure, or if it detects that you are accelerating, braking or actively steering. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 224 Driving and Operating { Warning Warning (Continued) 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. If LKA only detects lane markings on one side of the road, it will only assist or provide an LDW alert when approaching 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 windshield, 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. 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 windshield or headlamps are blocked by dirt, snow, or ice; if they are not in proper condition; or if the sun shines directly into the camera. . Detect road edges. . Detect lanes on winding or hilly roads. (Continued) { Warning Using LKA while towing a trailer or on slippery roads could cause loss of control of the vehicle and a crash. Turn the system off. How the System Works LKA uses a camera sensor installed on the windshield ahead of the rearview mirror to detect lane markings. It may provide brief steering assist 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. www.carobook.com To turn LKA on and off, press A on the center console. If equipped, the indicator light on the button comes on when LKA is on and turns off when LKA is disabled. When on, 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 Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Driving and Operating 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 take steering alerts. When the System Does Not Seem to Work Properly The system performance may be affected by: . Close vehicles ahead. 225 . Sudden lighting changes, such as when driving through tunnels. Fuel . Banked roads. Top Tier Fuel . Roads with poor lane markings, such as two-lane roads. GM recommends the use of TOP TIER Detergent Gasoline to keep the engine clean, reduce engine deposits, and maintain optimal vehicle performance. Look for the TOP TIER Logo or see www.toptiergas.com for a list of TOP TIER Detergent Gasoline marketers and applicable countries. 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 windshield behind the rear view mirror. www.carobook.com 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.

To tow a disabled vehicle, see Towing the Vehicle 0 323. To tow the vehicle behind another vehicle such as a motor home, see Recreational Vehicle Towing 0 324. www.carobook.com Driving Characteristics and Towing Tips { Warning The driver can lose control when pulling a trailer if the correct equipment is not used or the vehicle is not driven properly. For example, if the trailer is too heavy (Continued) 229 Warning (Continued) or the trailer brakes are inadequate for the load, the vehicle may not stop as expected. The driver and passengers could be seriously injured. The vehicle may also be damaged; the resulting repairs would not be covered by the vehicle warranty. Pull a trailer only if all the steps in this section have been followed. Ask your dealer for advice and information about towing a trailer with the vehicle. Driving with a Trailer Trailering is different than just driving the vehicle by itself. Trailering means changes in handling, acceleration, braking, durability, and fuel economy. Successful, safe trailering takes correct equipment, and it has to be used properly. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 230 Driving and Operating The following information has many time-tested, important trailering tips and safety rules. Many of these are important for your safety and that of your passengers. Read this section carefully before pulling a trailer. When towing a trailer: . Become familiar with and follow all state and local laws that apply to trailer towing. These requirements vary from state to state. . State laws may require the use of extended side view mirrors. Even if not required, you should install extended side view mirrors if your visibility is limited or restricted while towing. . Do not tow a trailer during the first 800 km (500 mi) of vehicle use to prevent damage to the engine, axle, or other parts. . It is recommended to perform the first oil change before heavy towing. . . During the first 800 km (500 mi) of trailer towing, do not drive over 80 km/h (50 mph) and do not make starts at full throttle. Vehicles can tow in D (Drive). Tow/Haul Mode is recommended for heavier trailers. See Tow/ Haul Mode 0 190. If the transmission downshifts too often, a lower gear may be selected using Manual Mode. See Manual Mode 0 189. If equipped, Driver Assistance Systems must be turned off when towing a trailer: . Adaptive Cruise Control (ACC) . Intelligent Brake Assist (IBA) . Front Pedestrian Braking (FPB) If equipped with Lane Change Alert (LCA), the LCA detection zones that extend back from the side of the vehicle do not move further back when a trailer is towed. Use caution while changing lanes when towing a trailer. If equipped with Rear Cross Traffic Alert (RCTA), use caution while backing up when towing a trailer, as the RCTA detection zones that extend out from the back of the vehicle do not move further back when a trailer is towed. www.carobook.com . Lane Keep Assist (LKA) . Park Assist . 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) { Warning To prevent serious injury or death from carbon monoxide (CO), when towing a trailer: . Do not drive with the liftgate, trunk/hatch, or rear-most window open. (Continued) Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Driving and Operating Warning (Continued) . Fully open the air outlets on or under the instrument panel. . Adjust the climate control system to a setting that brings in only outside air. See “Climate Control Systems” in the Index. For more information about carbon monoxide, see Engine Exhaust 0 186. Before driving, inspect all trailer hitch parts and attachments, safety chains, electrical connectors, lamps, tires, and mirrors. See Towing Equipment 0 237. If the trailer has electric brakes, start the combination moving and then manually apply the trailer brake controller to check that the trailer brakes work. During the trip, occasionally check that the cargo and trailer are secure and that the lamps and any trailer brakes are working. www.carobook.com Towing with a Stability Control Towing a trailer requires experience. The combination of the vehicle and trailer is longer and not as responsive as the vehicle itself. Get used to the handling and braking of the combination by driving on a level road surface before driving on public roads. System The trailer structure, the tires, and the brakes must all be rated to carry the intended cargo. Inadequate trailer equipment can cause the combination to operate in an unexpected or unsafe manner. Following Distance 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. 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. 231 Passing More passing distance is needed when towing a trailer. The combination of the vehicle and trailer will not accelerate as quickly and is much longer than the vehicle alone. It is necessary to go much farther beyond the passed vehicle before returning to the lane. Pass on level roadways. Avoid passing on hills if possible. Backing Up Hold the bottom of the steering wheel with one hand. To move the trailer to the left, move that hand to the left. To move the trailer to the right, move that hand to the right. Always back up slowly and, if possible, have someone guide you. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 232 Driving and Operating Making Turns Caution Turn more slowly and make wider arcs when towing a trailer to prevent damage to your vehicle. Making very sharp turns could cause the trailer to contact the vehicle. Make wider turns than normal when towing, so the trailer will not go over soft shoulders, over curbs, or strike road signs, trees, or other objects. Always signal turns well in advance. Do not steer or brake suddenly. Driving on Grades Reduce speed and shift to a lower gear before starting down a long or steep downhill grade. If the transmission is not shifted down, the brakes may overheat and result in reduced braking efficiency. The vehicle can tow in D (Drive). Shift the transmission to a lower gear if the transmission shifts too often under heavy loads and/or hilly conditions. 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 0 264. Parking on Hills { Warning To prevent serious injury or death, always park your vehicle and trailer on a level surface when possible. When parking the vehicle and trailer on a hill: www.carobook.com 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. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Driving and Operating 4. Reapply the brake pedal. Then apply the parking brake and shift into P (Park). 5. Release the brake pedal. Leaving After Parking on a Hill 1. Apply and hold the brake pedal. . Start the engine. . Shift into a gear. . Release the parking brake. 2. Let up on the brake pedal. 3. Drive slowly until the trailer is clear of the chocks. 4. Stop and have someone pick up and store the chocks. Maintenance When Trailer Towing The vehicle needs service more often when used to tow trailers. See the Maintenance Schedule 0 339. It is especially important to check the 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 0 264. Trailer Towing Caution www.carobook.com Towing a trailer improperly can damage the vehicle and result in costly repairs not covered by the vehicle warranty. To tow a trailer correctly, follow the directions in this section and see your dealer for important information about towing a trailer with the vehicle. 233 Trailer Weight { Warning Never exceed the towing capacity for your vehicle. Safe trailering requires monitoring the weight, speed, altitude, road grades, outside temperature, dimensions of the front of the trailer, and how frequently the vehicle is used to tow a trailer. Trailer Weight Ratings When towing a trailer, the combined weight of the vehicle, vehicle contents, trailer, and trailer contents must be below all of the maximum weight ratings for the vehicle, including: . GCWR: Gross Combined Weight Rating . GVWR: Gross Vehicle Weight Rating Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 234 Driving and Operating . Maximum Trailer Weight Rating . Maximum Trailer Tongue Weight Rating See “Weight-Distributing Hitch Adjustment” under Towing Equipment 0 237 to determine if equalizer bars are required to obtain the maximum trailer weight rating. See “Trailer Brakes” under Towing Equipment 0 237 to determine if brakes are required based on your trailer's weight. The only way to be sure the weight is not exceeding any of these ratings is to weigh the tow vehicle and trailer combination, fully loaded for the trip, getting individual weights for each of these items. { 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. Gross Combined Weight Rating (GCWR) GCWR is the total allowable weight of the completely loaded vehicle and trailer including any fuel, passengers, cargo, equipment, and accessories. Do not exceed the GCWR for your vehicle. The GCWR for the vehicle is on the tow rating chart later in this section. To check that the weight of the vehicle and trailer are within the GCWR for the vehicle, follow these steps: www.carobook.com Only tow a trailer if all the steps in this section have been followed. Ask your dealer for advice and information about towing a trailer. 1. Start with the "curb weight" from the Trailering Information label. 2. Add the weight of the trailer loaded with cargo and ready for the trip. 3. Add the weight of all passengers. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Driving and Operating Maximum Trailer Weight 4. Add the weight of all cargo in the vehicle. The maximum trailer weight rating is calculated assuming the tow vehicle has a driver, a front seat passenger, and all required trailering equipment. This value represents the heaviest trailer the vehicle can tow, but it may be necessary to reduce the trailer weight to stay within the GCW, GVWR, maximum trailer tongue load, or GAWR-RR for the vehicle. 5. Add the weight of hitch hardware such as a draw bar, ball, load equalizer bars, or sway bars. 6. Add the weight of any accessories or aftermarket equipment added to the vehicle. The resulting weight cannot exceed the GCWR value on the Trailering Information label. The gross combined weight can also be confirmed by weighing the truck and trailer on a public scale. The truck and trailer should be loaded for the trip with passengers and cargo. 235 Gross Vehicle Weight Rating (GVWR) www.carobook.com For information about the vehicle's maximum load capacity, see Vehicle Load Limits 0 174. When calculating the GVWR with a trailer attached, the trailer tongue weight must be included as part of the weight the vehicle is carrying. Use the tow rating chart to determine how much the trailer can weigh, based on the vehicle model, powertrain, and trailering options. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 236 Driving and Operating Vehicle Maximum Trailer Weight *GCWR 2.0L L4 Engine FWD 680 kg (1,500 lb) 2 812 kg (6,200 lb) 2.0L L4 Engine AWD 680 kg (1,500 lb) 2 812 kg (6,200 lb) 2.5L L4 Engine FWD 680 kg (1,500 lb) 2 625 kg (5,787 lb) 3.6L V6 Engine FWD 680 kg (1,500 lb) 2 722 kg (6,001 lb) 3.6L V6 Engine AWD 680 kg (1,500 lb) 2 722 kg (6,001 lb) 2 041 kg (4,500 lb) 4 155 kg (9,250 lb) 3.6L V6 Engine AWD w/V92 Option (Heavy Duty Towing) *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. www.carobook.com Maximum Trailer Tongue Weight Rating Do not exceed a maximum trailer tongue weight of 204 kg (450 lb). 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. The trailer tongue weight contributes to the Gross Vehicle Weight (GVW). GVW includes the CURB WEIGHT of your vehicle, any passengers, cargo, equipment, and trailer tongue weight. Vehicle options, passengers, cargo, and equipment reduce the maximum allowable tongue weight the vehicle can carry, which also reduces the maximum allowable trailer weight. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Driving and Operating 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. After loading the trailer, separately weigh the trailer and then the trailer tongue and calculate the trailer load balance percentage to see if the weights and distribution are appropriate for your vehicle. If the trailer weight is too high, it may be possible to transfer some of the cargo into your vehicle. If the trailer tongue weight is too high or too low, it may be possible to rearrange some of the cargo inside of the trailer. Do not exceed the maximum allowable tongue weight for your www.carobook.com The trailer tongue weight (1) should be 10–15% of the loaded trailer weight (2). Some specific trailer types, such as boat trailers, fall outside of 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. 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. 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 237 half of the maximum allowable tongue weight for the vehicle or 227 kg (500 lb), whichever is less. Ask your dealer for trailering information or assistance. Towing Equipment Hitches Always use the correct hitch equipment for your vehicle. Crosswinds, large trucks going by, and rough roads can affect the trailer and the hitch. Never attach rental hitches or other bumper-type hitches.

Do not tow a trailer while using a compact spare tire on the vehicle. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Driving and Operating . Tires must be properly inflated to support loads while towing a trailer. See Tires 0 284 for instructions on proper tire inflation. Safety Chains Always attach chains between the vehicle and the trailer, and attach the chains to the holes on the trailer hitch platform. Instructions for safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. Association (CSA) requirement CAN3-D313, or its equivalent, is recommended. State or local regulations may require trailers to have their own braking system if the loaded weight of the trailer exceeds certain minimums that can vary from state to state. Read and follow the instructions for the trailer brakes so they are installed, adjusted, and maintained properly. Never attempt to tap into your vehicle's hydraulic brake system. If you do, both the vehicle antilock brakes and the trailer brakes may not function, which could result in a crash. www.carobook.com 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 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 Trailer Wiring Harness Basic Trailer Wiring The trailer wiring harness, with a seven-pin connector, is at the rear of the vehicle and is tied to the vehicle's frame.

Trailer Sway Control (TSC) Vehicles with StabiliTrak/Electronic Stability Control (ESC) have a Trailer Sway Control (TSC) feature. Trailer sway is unintended side-to-side motion of a trailer while towing. If the vehicle is towing a trailer and the TSC detects that sway is increasing, the vehicle brakes are selectively applied at each wheel, to help reduce excessive trailer sway. If equipped with the Integrated Trailer Brake Control (ITBC) system, and the trailer has an electric brake system, StabiliTrak/ESC may also apply the trailer brakes. If TSC is enabled, the Traction Control System (TCS)/StabiliTrak 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 0 194. { Warning www.carobook.com Trailer sway can result in a crash and in serious injury or death, even if the vehicle is equipped with TSC. If the trailer begins to sway, reduce vehicle speed by gradually removing your foot from the accelerator. Then pull over to check the trailer and vehicle to help correct possible causes, including an improperly or overloaded trailer, unrestrained (Continued) 241 Warning (Continued) cargo, improper trailer hitch configuration, or improperly inflated or incorrect vehicle or trailer tires. See Towing Equipment 0 237 for trailer ratings and hitch setup recommendations. Trailer Tires Special Trailer (ST) tires differ from vehicle tires. Trailer tires are designed with stiff sidewalls to help prevent sway and to support heavy loads. These features can make it difficult to determine if the trailer tire pressures are low only based on a visual inspection. Always check all trailer tire pressures before each trip when the tires are cool. Low trailer tire pressure is a leading cause of trailer tire blowouts. Trailer tires deteriorate over time. The trailer tire sidewall will show the week and year the tire was Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 242 Driving and Operating manufactured. Many trailer tire manufacturers recommend replacing tires more than six years old. Conversions and Add-Ons Overloading is another leading cause of trailer tire blowouts. Never load your trailer with more weight than the tires are designed to support. The load rating is on the trailer tire sidewall. Add-On Electrical Equipment Always know the maximum speed rating for the trailer tires before driving. This may be significantly lower than the vehicle tire speed rating. The speed rating may be on the trailer tire sidewall. If the speed rating is not shown, the default trailer tire speed rating is 105 km/h (65 mph). { Warning The Data Link Connector (DLC) is used for vehicle service and Emission Inspection/ Maintenance testing. See Malfunction Indicator Lamp (Check Engine Light) 0 120. A device connected to the DLC — such as an aftermarket fleet or driver-behavior tracking device — may interfere with vehicle systems. This could affect vehicle operation and cause a crash. Such devices may also access information stored in the vehicle’s systems. Caution Some electrical equipment can damage the vehicle or cause components to not work and would not be covered by the vehicle warranty. Always check with your dealer before adding electrical equipment. Add-on equipment can drain the vehicle's 12-volt battery, even if the vehicle is not operating. www.carobook.comThe vehicle has an airbag system.

Selecting the Right Engine Oil Selecting the right engine oil depends on both the proper oil specification and viscosity grade. See Recommended Fluids and Lubricants 0 348. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Vehicle Care Specification Use full synthetic engine oils that meet the dexos1 specification. Engine oils that have been approved by GM as meeting the dexos1 specification are marked with the dexos1 approved logo. See www.gmdexos.com. Use SAE 5W-30 viscosity grade engine oil for the 3.6L V6 engine. Cold Temperature Operation: In an area of extreme cold, where the temperature falls below −29 °C (−20 °F), an SAE 0W-30 oil may be used. An oil of this viscosity grade will provide easier cold starting for the engine at extremely low temperatures. When selecting an oil of the appropriate viscosity grade, it is recommended to select an oil of the correct specification. See “Specification” earlier in this section. www.carobook.com Caution Failure to use the recommended engine oil or equivalent can result in engine damage not covered by the vehicle warranty. Viscosity Grade Use SAE 0W-20 viscosity grade engine oil for the 2.0L L4 and 2.5L L4 engines. Engine Oil Additives/Engine Oil Flushes Do not add anything to the oil. The recommended oils meeting the dexos1 specification are all that is needed for good performance and engine protection. Engine oil system flushes are not recommended and could cause engine damage not covered by the vehicle warranty. 255 What to Do with Used Oil Used engine oil contains certain elements that can be unhealthy for your skin and could even cause cancer. Do not let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine oil. See the manufacturer's warnings about the use and disposal of oil products. Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil by putting it in the trash or pouring it on the ground, into sewers, or into streams or bodies of water. Recycle it by taking it to a place that collects used oil. Engine Oil Life System When to Change Engine Oil This vehicle has a computer system that indicates when to change the engine oil and filter. This is based on a combination of factors which Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 256 Vehicle Care include engine revolutions, engine temperature, and miles driven. Based on driving conditions, the mileage at which an oil change is indicated can vary considerably. For the oil life system to work properly, the system must be reset every time the oil is changed. When the system has calculated that oil life has been diminished, it indicates that an oil change is necessary. A CHANGE ENGINE OIL SOON message comes on. Change the oil as soon as possible within the next 1 000 km (600 mi). It is possible that, if driving under the best conditions, the oil life system might indicate that an oil change is not necessary for up to a year. The engine oil and filter must be changed at least once a year and, at this time, the system must be reset. Your dealer has trained service people who will perform this work and reset the system. It is also important to check the oil regularly over the course of an oil drain interval and keep it at the proper level. If the system is ever reset accidentally, the oil must be changed at 5 000 km (3,000 mi) since the last oil change. Remember to reset the oil life system whenever the oil is changed. The oil life system can also be reset as follows: 1. Place the ignition in Service Mode. See Ignition Positions 0 178. 2. Display REMAINING OIL LIFE on the DIC menu.

These tires are designed to provide good overall performance on most road surfaces and weather conditions. Original equipment tires designed to GM's specific tire performance criteria have a TPC specification code molded onto the sidewall. Original equipment all-season tires can be identified by the last two characters of this TPC code, which will be “MS.” This vehicle was not originally equipped with winter tires. Winter tires are designed for increased traction on snow and ice-covered roads. Consider installing winter tires on the vehicle if frequent driving on ice or snow covered roads is expected. See your dealer for details regarding winter tire availability and proper tire selection. Also, see Buying New Tires 0 301. www.carobook.com Consider installing winter tires on the vehicle if frequent driving on snow or ice-covered roads is expected. All-season tires provide adequate performance for most winter driving conditions, but they may not offer the same level of traction or performance as winter tires on snow or ice-covered roads. See Winter Tires 0 285. With winter tires, there may be decreased dry road traction, increased road noise, and shorter tread life. After changing to winter tires, be alert for changes in vehicle handling and braking. If using winter tires: . Use tires of the same brand and tread type on all four wheel positions. . Use only radial ply tires of the same size, load range, and speed rating as the original equipment tires. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 286 Vehicle Care Winter tires with the same speed rating as the original equipment tires may not be available for H, V, W, Y, and ZR speed rated tires. If winter tires with a lower speed rating are chosen, never exceed the tire's maximum speed capability. Summer Tires This vehicle may come with 235/55R20 high performance summer tires. These tires have a special tread and compound that are optimized for maximum dry and wet road performance. This special tread and compound will have decreased performance in cold climates, and on ice and snow. It is recommended that winter tires be installed on the vehicle if frequent driving at temperatures below approximately 5 °C (40 °F) or on ice or snow covered roads is expected. See Winter Tires 0 285. 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 tires. Always inspect tires before use. See Tire Inspection 0 298.

Underinflated tires, or tires that do not have enough air, can result in: . Tire overloading and overheating, which could lead to a blowout. . Premature or irregular wear. . Poor handling. . Reduced fuel economy. Overinflated tires, or tires that have too much air, can result in: . Unusual wear. . Poor handling. . Rough ride. . Needless damage from road hazards. The Tire and Loading Information label on the vehicle indicates the original equipment tires and the correct cold tire inflation pressures. The recommended pressure is the minimum air pressure needed to support the vehicle's maximum load carrying capacity. See Vehicle Load Limits 0 174. How to Check How the vehicle is loaded affects vehicle handling and ride comfort. Never load the vehicle with more weight than it was designed to carry. Remove the valve cap from the tire valve stem. Press the tire gauge firmly onto the valve to get a pressure measurement. If the cold tire inflation pressure matches the recommended pressure on the Tire and Loading Information label, no further adjustment is necessary. If the inflation pressure is low, add air until the recommended pressure is reached. If the inflation pressure is high, press on the metal stem in the center of the tire valve to release air. Use a good quality pocket-type gauge to check tire pressure. Proper tire inflation cannot be determined by looking at the tire. Check the tire inflation pressure when the tires are cold, meaning the vehicle has not been driven for at least three hours or no more than 1.6 km (1 mi). www.carobook.com When to Check Check the pressure of the tires once a month or more. Do not forget the compact spare, if the vehicle has one. The cold compact spare tire pressure should be at 420 kPa (60 psi). See Compact Spare Tire 0 320. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Vehicle Care Recheck the tire pressure with the tire gauge. Put the valve caps back on the valve stems to keep out dirt and moisture and prevent leaks. Use only valve caps designed for the vehicle by GM. TPMS sensors could be damaged and would not be covered by the vehicle warranty. Tire Pressure for High-Speed Operation { Warning Driving at high speeds, 160 km/h (100 mph) or higher, puts additional strain on tires. Sustained high-speed driving causes excessive heat buildup and can cause sudden tire failure. This could cause a crash, and you or others could be killed. Some high-speed rated tires require inflation pressure (Continued) Warning (Continued) adjustment for high-speed operation. When speed limits and road conditions allow the vehicle to be driven at high speeds, make sure the tires are rated for high-speed operation, are in excellent condition, and are set to the correct cold tire inflation pressure for the vehicle load. Vehicles with 235/65R18, www.carobook.com 235/55R20 or 265/45R21 size tires require inflation pressure adjustment when driving the vehicle at speeds of 160 km/h (100 mph) or higher. Set the cold inflation pressure to the maximum inflation pressure shown on the tire sidewall, or 280 kPa (41 psi), whichever is lower. Return the tires to the recommended cold tire inflation pressure when high-speed driving has ended. See Vehicle Load Limits 0 174 and Tire Pressure 0 291. 293 The maximum load and inflation pressure is molded on the tire sidewall, in small letters, near the rim flange. It will read something like this: Maximum load 690 kg (1,521 lbs) 300 kPa (44 psi) Max. Press. Tire Pressure Monitor System The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check tire pressure levels. The TPMS sensors monitor the air pressure in your tires and transmit tire pressure readings to a receiver located in the vehicle. Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.) Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 294 Vehicle Care As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly. See Tire Pressure Monitor Operation 0 294. See Radio Frequency Statement 0 365. Tire Pressure Monitor Operation This vehicle may have a Tire Pressure Monitor System (TPMS). The TPMS is designed to warn the driver when a low tire pressure condition exists. TPMS sensors are mounted onto each tire and wheel assembly, excluding the spare tire and wheel assembly. The TPMS sensors monitor the air pressure in the tires and transmit the tire pressure readings to a receiver located in the vehicle. www.carobook.com Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Vehicle Care When a low tire pressure condition is detected, the TPMS illuminates the low tire pressure warning light located on the instrument cluster. If the warning light comes on, stop as soon as possible and inflate the tires to the recommended pressure shown on the Tire and Loading Information label. See Vehicle Load Limits 0 174. A message to check the pressure in a specific tire displays in the Driver Information Center (DIC). The low tire pressure warning light and the DIC warning message come on at each ignition cycle until the tires are inflated to the correct inflation pressure. Using the DIC, tire pressure levels can be viewed. For additional information and details about the DIC operation and displays see Driver Information Center (DIC) (Base and Midlevel) 0 129 or Driver Information Center (DIC) (Uplevel) 0 133. The low tire pressure warning light may come on in cool weather when the vehicle is first started, and then turn off as the vehicle is driven. This could be an early indicator that the air pressure is getting low and needs to be inflated to the proper pressure. A Tire and Loading Information label, attached to your vehicle, shows the size of the original equipment tires and the correct inflation pressure for the tires when they are cold. See Vehicle Load Limits 0 174, for an example of the Tire and Loading Information label and its location. Also see Tire Pressure 0 291. www.carobook.com The TPMS can warn about a low tire pressure condition but it does not replace normal tire maintenance. See Tire Inspection 0 298, Tire Rotation 0 299 and Tires 0 284. Caution Tire sealant materials are not all the same. A non-approved tire sealant could damage the TPMS (Continued) 295 Caution (Continued) sensors. TPMS sensor damage caused by using an incorrect tire sealant is not covered by the vehicle warranty. Always use only the GM approved tire sealant available through your dealer or included in the vehicle. Factory-installed Tire Inflator Kits use a GM-approved liquid tire sealant. Using non-approved tire sealants could damage the TPMS sensors. See Tire Sealant and Compressor Kit 0 307 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 tire pressure warning light flashes for about one minute and then stays on for the remainder of the ignition cycle. A DIC warning Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 296 Vehicle Care message also displays. The malfunction light and DIC warning message come on at each ignition cycle until the problem is corrected. Some of the conditions that can cause these to come on are: . One of the road tires has been replaced with the spare tire. The spare tire does not have a TPMS sensor. The malfunction light and DIC message should go off after the road tire is replaced and the sensor matching process is performed successfully. See “TPMS Sensor Matching Process” later in this section. . The TPMS sensor matching process was not done or not completed successfully after rotating the tires. The malfunction light and the DIC message should go off after successfully completing the sensor matching process. See "TPMS Sensor Matching Process" later in this section. . . One or more TPMS sensors are missing or damaged. The malfunction light and the DIC message should go off when the TPMS sensors are installed and the sensor matching process is performed successfully. See your dealer for service. Replacement tires or wheels do not match the original equipment tires or wheels. Tires and wheels other than those recommended could prevent the TPMS from functioning properly. See Buying New Tires 0 301. Tire Fill Alert (If Equipped) This feature provides visual and audible alerts outside the vehicle to help when inflating an underinflated tire to the recommended cold tire pressure. When the low tire pressure warning light comes on: 1. Park the vehicle in a safe, level place. 2. Set the parking brake firmly. 3. Place the vehicle in P (Park). www.carobook.com 4. . Operating electronic devices or being near facilities using radio wave frequencies similar to the TPMS could cause the TPMS sensors to malfunction. If the TPMS is not functioning properly it cannot detect or signal a low tire pressure condition. See your dealer for service if the TPMS malfunction light and DIC message come on and stay on. Add air to the tire that is underinflated. The turn signal lamp will flash. When the recommended pressure is reached, the horn sounds once and the turn signal lamp will stop flashing and briefly turn solid. Repeat these steps for all underinflated tires that have illuminated the low tire pressure warning light. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Vehicle Care { Warning Overinflating a tire could cause the tire to rupture and you or others could be injured. Do not exceed the maximum pressure listed on the tire sidewall. See Tire Sidewall Labeling 0 286 and Vehicle Load Limits 0 174. If the tire is overinflated by more than 35 kPa (5 psi), the horn will sound multiple times and the turn signal lamp will continue to flash for several seconds after filling stops. To release and correct the pressure, while the turn signal lamp is still flashing, briefly press the center of the valve stem. When the recommended pressure is reached, the horn sounds once. www.carobook.com If the turn signal lamp does not flash within 15 seconds after starting to inflate the tire, the tire fill alert has not been activated or is not working. If the hazard warning flashers are on, the tire fill alert visual feedback will not work properly. The TPMS will not activate the tire fill alert properly under the following conditions: . There is interference from an external device or transmitter. . The air pressure from the inflation device is not sufficient to inflate the tire. . There is a malfunction in the TPMS. . There is a malfunction in the horn or turn signal lamps. . The identification code of the TPMS sensor is not registered to the system. . The battery of the TPMS sensor is low. If the tire fill alert does not operate due to TPMS interference, move the vehicle about 1 m (3 ft) back or forward and try again. If the tire fill alert feature is not working, use a tire pressure gauge. 297 TPMS Sensor Matching Process Each TPMS sensor has a unique identification code. The identification code needs to be matched to a new tire/wheel position after rotating the vehicle’s tires or replacing one or more of the TPMS sensors. The TPMS sensor matching process should also be performed after replacing a spare tire with a road tire containing the TPMS sensor. The malfunction light and the DIC message should go off at the next ignition cycle. The sensors are matched to the tire/wheel positions, using a TPMS relearn tool, in the following order: driver side front tire, passenger side front tire, passenger side rear tire, and driver side rear tire. See your dealer for service or to purchase a relearn tool. A TPMS relearn tool can also be purchased. See Tire Pressure Monitor Sensor Activation Tool at www.gmtoolsandequipment.com or call 1-800-GM TOOLS (1-800-468-6657). Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 298 Vehicle Care There are two minutes to match the first tire/wheel position, and five minutes overall to match all four tire/wheel positions. If it takes longer, the matching process stops and must be restarted. The TPMS sensor matching process is: 1. Set the parking brake. 2. Place the vehicle in Service Mode. See Ignition Positions 0 178. 3. Make sure the Tire Pressure info page option is turned on. The info pages on the DIC can be turned on and off through the Options menu. See Driver Information Center (DIC) (Base and Midlevel) 0 129 or Driver Information Center (DIC) (Uplevel) 0 133. 4. Use the DIC controls on the right side of the steering wheel to scroll to the Tire Pressure screen under the DIC info page. 5. Press and hold the thumbwheel located in the center of the DIC controls on the right side of the steering wheel. The horn sounds twice to signal the receiver is in relearn mode and the TIRE LEARNING ACTIVE message displays on the DIC display. 6. Start with the driver side front tire. 7. Place the relearn tool against the tire sidewall, near the valve stem. Then press the button to activate the TPMS sensor. A horn chirp confirms that the sensor identification code has been matched to this tire and wheel position. 10. Proceed to the driver side rear tire, and repeat the procedure in Step 7. The horn sounds two times to indicate the sensor identification code has been matched to the driver side rear tire, and the TPMS sensor matching process is no longer active. The TIRE LEARNING ACTIVE message on the DIC display goes off. 11. Turn the vehicle off. 12. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading Information label. www.carobook.com 8. Proceed to the passenger side front tire, and repeat the procedure in Step 7. 9. Proceed to the passenger side rear tire, and repeat the procedure in Step 7. Tire Inspection We recommend that the tires, including the spare tire, if the vehicle has one, be inspected for signs of wear or damage at least once a month. Replace the tire if: . The indicators at three or more places around the tire can be seen. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Vehicle Care . There is cord or fabric showing through the tire's rubber. . The tread or sidewall is cracked, cut, or snagged deep enough to show cord or fabric. . The tire has a bump, bulge, or split. . The tire has a puncture, cut, or other damage that cannot be repaired well because of the size or location of the damage. Anytime unusual wear is noticed, rotate the tires as soon as possible, check for proper tire inflation pressure, and check for damaged tires or wheels. If the unusual wear continues after the rotation, check the wheel alignment. See When It Is Time for New Tires 0 300 and Wheel Replacement 0 304. www.carobook.com If the vehicle has a compact spare tire, do not include it in the tire rotation. Adjust the front and rear tires to the recommended inflation pressure on the Tire and Loading Information label after the tires have been rotated. See Tire Pressure 0 291 and Vehicle Load Limits 0 174. Reset the Tire Pressure Monitor System. See Tire Pressure Monitor Operation 0 294. Check that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Specifications 0 352. Tire Rotation Tires should be rotated every 12 000 km (7,500 mi). See Maintenance Schedule 0 339. Tires are rotated to achieve a uniform wear for all tires. The first rotation is the most important. 299 { Warning Use this rotation pattern when rotating the tires. Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after time. The wheel could come off and (Continued) Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 300 Vehicle Care Warning (Continued) 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 a paper towel can be used; however, use a scraper or wire brush later to remove all rust or dirt. Lightly coat the inner diameter of the wheel hub opening with wheel bearing grease after a wheel change or tire rotation to prevent corrosion or rust build-up. Do not get grease on the wheel mounting surface or on the wheel nuts or bolts. When It Is Time for New Tires Factors such as maintenance, temperatures, driving speeds, vehicle loading, and road conditions affect the wear rate of the tires. The rubber in tires ages over time. This also applies to the spare tire, if the vehicle has one, even if it is never used. Multiple factors including temperatures, loading conditions, and inflation pressure maintenance affect how fast aging takes place. GM recommends that tires, including the spare if equipped, be replaced after six years, regardless of tread wear. To identify the age of a tire, use the tire manufacture date which is the last four digits of the DOT Tire Identification Number (TIN) which is molded into one side of the tire sidewall. The first two digits represent the week (01–52) and the last two digits, the year. For example, the third week of the year 2010 would have a four-digit DOT date of 0310. www.carobook.com Treadwear indicators are one way to tell when it is time for new tires. Treadwear indicators appear when the tires have only 1.6 mm (1/16 in) or less of tread remaining. See Tire Inspection 0 298 and Tire Rotation 0 299. Vehicle Storage Tires age when stored normally mounted on a parked vehicle. Park a vehicle that will be stored for at least a month in a cool, dry, clean area away from direct sunlight to slow aging. This area should be free Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Vehicle Care of grease, gasoline, or other substances that can deteriorate rubber. Parking for an extended period can cause flat spots on the tires that may result in vibrations while driving. When storing a vehicle for at least a month, remove the tires or raise the vehicle to reduce the weight from the tires. Buying New Tires GM has developed and matched specific tires for the vehicle. The original equipment tires installed were designed to meet General Motors Tire Performance Criteria Specification (TPC Spec) system rating. When replacement tires are needed, GM strongly recommends buying tires with the same TPC Spec rating. vehicle, including brake system performance, ride and handling, traction control, and tire pressure monitoring performance. GM's TPC Spec number is molded onto the tire's sidewall near the tire size. If the tires have an all-season tread design, the TPC Spec number will be followed by MS for mud and snow. See Tire Sidewall Labeling 0 286. GM recommends replacing worn www.carobook.com tires in complete sets of four. GM's exclusive TPC Spec system considers over a dozen critical specifications that impact the overall performance of the Uniform tread depth on all tires will help to maintain the performance of the vehicle. Braking and handling performance may be adversely affected if all the tires are not replaced at the same time. If proper rotation and maintenance have been done, all four tires should wear out at about the same time. See Tire Rotation 0 299. However, if it is 301 necessary to replace only one axle set of worn tires, place the new tires on the rear axle. Winter tires with the same speed rating as the original equipment tires may not be available for H, V, W, Y and ZR speed rated tires. Never exceed the winter tires’ maximum speed capability when using winter tires with a lower speed rating. { Warning Tires could explode during improper service. Attempting to mount or dismount a tire could cause injury or death. Only your dealer or authorized tire service center should mount or dismount the tires. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 302 Vehicle Care { Warning Mixing tires of different sizes, brands, or types may cause loss of control of the vehicle, resulting in a crash or other vehicle damage. Use the correct size, brand, and type of tires on all wheels. { Warning Using bias-ply tires on the vehicle may cause the wheel rim flanges to develop cracks after many miles of driving. A tire and/or wheel could fail suddenly and cause a crash. Use only radial-ply tires with the wheels on the vehicle. If the vehicle tires must be replaced with a tire that does not have a TPC Spec number, make sure they are the same size, load range, speed rating, and construction (radial) as the original tires. Vehicles that have a tire pressure monitoring system could give an inaccurate low-pressure warning if non-TPC Spec rated tires are installed. See Tire Pressure Monitor System 0 293. The Tire and Loading Information label indicates the original equipment tires on the vehicle. See Vehicle Load Limits 0 174. control, electronic stability control, or All-Wheel Drive, the performance of these systems can also be affected. { Warning www.carobook.com Different Size Tires and Wheels If wheels or tires are installed that are a different size than the original equipment wheels and tires, vehicle performance, including its braking, ride and handling characteristics, stability, and resistance to rollover may be affected. If the vehicle has electronic systems such as antilock brakes, rollover airbags, traction If different sized wheels are used, there may not be an acceptable level of performance and safety if tires not recommended for those wheels are selected. This increases the chance of a crash and serious injury. Only use GM specific wheel and tire systems developed for the vehicle, and have them properly installed by a GM certified technician. See Buying New Tires 0 301 and Accessories and Modifications 0 245. Uniform Tire Quality Grading The following information relates to the system developed by the United States National Highway Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Vehicle Care Traffic Safety Administration (NHTSA), which grades tires by treadwear, traction, and temperature performance. This applies only to vehicles sold in the United States. The grades are molded on the sidewalls of most passenger car tires. The Uniform Tire Quality Grading (UTQG) system does not apply to deep tread, winter tires, compact spare tires, tires with nominal rim diameters of 10 to 12 inches (25 to 30 cm), or to some limited-production tires. While the tires available on General Motors passenger cars and light trucks may vary with respect to these grades, they must also conform to federal safety requirements and additional General Motors Tire Performance Criteria (TPC) standards. 303 Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: norm due to variations in driving habits, service practices and differences in road characteristics and climate. Treadwear 200 Traction AA Temperature A The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics. All Passenger Car Tires Must Conform to Federal Safety Requirements In Addition To These Grades. Treadwear www.carobook.com The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one-half (1½) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the Traction Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 304 Vehicle Care Temperature The temperature grades are A (the highest), B, and C, representing the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. Warning: The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure. Wheel Alignment and Tire Balance The tires and wheels were aligned and balanced at the factory to provide the longest tire life and best overall performance. Adjustments to wheel alignment and tire balancing are not necessary on a regular basis. Consider an alignment check if there is unusual tire wear or the vehicle is significantly pulling to one side or the other. Some slight pull to the left or right, depending on the crown of the road and/or other road surface variations such as troughs or ruts, is normal. If the vehicle is vibrating when driving on a smooth road, the tires and wheels may need to be rebalanced. See your dealer for proper diagnosis. Wheel Replacement Replace any wheel that is bent, cracked, or badly rusted or corroded. If wheel nuts keep coming loose, the wheel, wheel bolts, and wheel nuts should be replaced. If the wheel leaks air, replace it. Some aluminum wheels can be repaired. See your dealer if any of these conditions exist. Your dealer will know the kind of wheel that is needed. new wheel should have the www.carobook.comEach same load-carrying capacity, diameter, width, offset, and be mounted the same way as the one it replaces. Replace wheels, wheel bolts, wheel nuts, or Tire Pressure Monitor System (TPMS) sensors with new GM original equipment parts. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/24/20 Vehicle Care { Warning Using the wrong replacement wheels, wheel bolts, or wheel nuts can be dangerous. It could affect the braking and handling of the vehicle. Tires can lose air, and cause loss of control, causing a crash. Always use the correct wheel, wheel bolts, and wheel nuts for replacement. Caution The wrong wheel can also cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height, vehicle ground clearance, and tire or tire chain clearance to the body and chassis. Used Replacement Wheels { Warning Replacing a wheel with a used one is dangerous. How it has been used or how far it has been driven may be unknown. It could fail suddenly and cause a crash.

Install them on the tires of the front axle. Do not use chains on the tires 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 them. If the contact continues, slow down until it stops. Driving too fast or spinning the wheels with chains on will damage the vehicle. If a Tire Goes Flat It is unusual for a tire to blow out while driving, especially if the tires are maintained properly. See Tires 0 284. If air goes out of a tire, 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 tire fails, the flat tire creates a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel firmly. Steer to maintain lane position, and then gently brake to a stop, well off the road, if possible. A rear blowout, particularly on a curve, acts much like a skid and may require the same correction as used in a skid. Stop pressing the accelerator pedal and steer to straighten the vehicle. It may be very bumpy and noisy. Gently brake to a stop, well off the road, if possible. Warning (Continued) severely underinflated or flat.

Normally, any concerns with the sales transaction or the operation of the vehicle will be resolved by your dealer's sales or service departments.

If your concern has not been resolved to your satisfaction, the following steps should be taken: STEP ONE : Discuss your concern with a member of dealership management. Normally, concerns can be quickly resolved at that level. If the matter has already been reviewed with the sales, service, or parts manager, contact the owner of your dealership or the general manager. STEP TWO : If after contacting a member of dealership management, it appears your concern cannot be Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/26/20 356 Customer Information resolved by your dealership without further help, in the U.S., call the Chevrolet Customer Assistance Center at 1-800-222-1020.

However, if you continue to remain unsatisfied after following the procedure outlined in Steps One and Two, you can file with the Better Business Bureau (BBB) Auto Line Program to enforce your rights. The BBB Auto Line Program is an out-of-court program administered by BBB National Programs, Inc. to settle automotive disputes regarding vehicle repairs or the interpretation of the New Vehicle Limited Warranty. Although you may be required to resort to this informal dispute resolution program prior to filing a court action, use of the program is free of charge and your case will generally be heard within 40 days. If you do not agree with the decision given in your case, you may reject it and proceed with any other venue for relief available to you. You may contact the BBB Auto Line Program using the toll-free telephone number or write them at the following address: BBB Auto Line Program BBB National Programs, Inc. 3033 Wilson Boulevard Suite 600 Arlington, VA 22201 Telephone: 1-800-955-5100 http://www.bbb.org/council/ programs-services/ dispute-handling-and-resolution/ bbb-auto-line www.carobook.comThis program is available in all 50 states and the District of Columbia.

Collision Parts Genuine GM Collision parts are new parts made with the same materials and construction methods as the parts with which the vehicle was originally built. Genuine GM Collision parts are the best choice to ensure that the vehicle's designed appearance, durability, and safety are preserved. The use of Genuine GM parts can help maintain the GM New Vehicle Limited Warranty. Recycled original equipment parts may also be used for repair. These parts are typically removed from vehicles that were total losses in prior crashes. In most cases, the parts being recycled are from undamaged sections of the vehicle. A recycled original equipment GM part may be an acceptable choice to maintain the vehicle's originally designed appearance and safety performance; however, the history of these parts is not known. Such parts are not covered by the GM New Vehicle Limited Warranty, and any related failures are not covered by that warranty. www.carobook.com Collision Damage Repair If the vehicle is involved in a collision and it is damaged, have the damage repaired by a qualified technician using the proper equipment and quality replacement parts. Poorly performed collision repairs diminish the vehicle resale value, and safety performance can be compromised in subsequent collisions. Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/26/20 Customer Information Aftermarket collision parts are also available. These are made by companies other than GM and may not have been tested for the vehicle. As a result, these parts may fit poorly, exhibit premature durability/ corrosion problems, and may not perform properly in subsequent collisions. Aftermarket parts are not covered by the GM New Vehicle Limited Warranty, and any vehicle failure related to such parts is not covered by that warranty. Repair Facility GM also recommends that you choose a collision repair facility that meets your needs before you ever need collision repairs. Your dealer may have a collision repair center with GM-trained technicians and state-of-the-art equipment, or be able to recommend a collision repair center that has GM-trained technicians and comparable equipment. Insuring the Vehicle Protect your investment in the GM vehicle with comprehensive and collision insurance coverage. There are significant differences in the quality of coverage afforded by various insurance policy terms. Many insurance policies provide reduced protection to the GM vehicle by limiting compensation for damage repairs through the use of aftermarket collision parts. Some insurance companies will not specify aftermarket collision parts. When purchasing insurance, we recommend that you ensure that the vehicle will be repaired with GM original equipment collision parts. If such insurance coverage is not available from your current insurance carrier, consider switching to another insurance carrier. www.carobook.com If the vehicle is leased, the leasing company may require you to have insurance that ensures repairs with Genuine GM Original Equipment Manufacturer (OEM) parts or Genuine Manufacturer replacement 363 parts. Read the lease carefully, as you may be charged at the end of the lease for poor quality repairs. If a Crash Occurs If there has been an injury, call emergency services for help. Do not leave the scene of a crash until all matters have been taken care of. Move the vehicle only if its position puts you in danger, or you are instructed to move it by a police officer. Give only the necessary information to police and other parties involved in the crash. For emergency towing see Roadside Assistance Program 0 359. Gather the following information: . Driver name, address, and telephone number . Driver license number . Owner name, address, and telephone number . Vehicle license plate number Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/26/20 364 Customer Information . Vehicle make, model, and model year .

General description of the damage to the other vehicle Choose a reputable repair facility that uses quality replacement parts. See “Collision Parts” earlier in this section. If the airbag has inflated, see What Will You See after an Airbag Inflates? 0 64. Managing the Vehicle Damage Repair Process In the event that the vehicle requires damage repairs, GM recommends that you take an active role in its repair. If you have a pre-determined repair facility of choice, take the vehicle there, or have it towed there. Specify to the facility that any required replacement collision parts be original equipment parts, either new Genuine GM parts or recycled original GM parts. Remember, recycled parts will not be covered by the GM vehicle warranty. Publication Ordering Information Insurance pays the bill for the repair, but you must live with the repair. Depending on your policy limits, your insurance company may initially value the repair using aftermarket parts. Discuss this with the repair professional, and insist on Genuine GM parts. Remember, if the vehicle is leased, you may be obligated to have the vehicle repaired with Genuine GM parts, even if your insurance coverage does not pay the full cost. Service Manuals Service manuals have the diagnosis and repair information on the engine, transmission, axle, suspension, brakes, electrical system, steering system, body, etc. Customer Literature Owner’s manuals are written specifically for owners and are intended to provide basic operational information about the vehicle. The owner’s manual includes the Maintenance Schedule for all models. www.carobook.com If another party's insurance company is paying for the repairs, you are not obligated to accept a repair valuation based on that insurance company's collision policy repair limits, as you have no contractual limits with that company. In such cases, you can have control of the repair and parts choices as long as the cost stays within reasonable limits. Customer literature publications available for purchase include owner’s manuals, warranty manuals, infotainment manuals, and portfolios.

GM collects information about the use of your vehicle including operational and safety related information. We collect this information to provide, evaluate, improve, and troubleshoot our products and services and to develop new products and services. The protection of vehicle electronics systems and customer data from unauthorized outside electronic access or control is important to GM. GM maintains appropriate security standards, practices, guidelines and controls aimed at defending the vehicle and the vehicle service ecosystem against unauthorized electronic access, detecting possible malicious activity in related networks, and responding to suspected cybersecurity incidents in a timely, coordinated and effective manner. Security incidents could impact your safety or compromise your private data. To minimize security risks, please do not connect your vehicle electronic systems to unauthorized devices or connect your vehicle to any unknown or www.carobook.com 367 untrusted networks (such as Bluetooth, WIFI or similar technology). In the event you suspect any security incident impacting your data or the safe operation of your vehicle, please stop operating your vehicle and contact your dealer. Event Data Recorders This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR is to record, in certain crash or near crash-like situations, such as an air bag deployment or hitting a road obstacle, data that will assist in understanding how a vehicle’s systems performed. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less. The EDR in this vehicle is designed to record such data as: . How various systems in your vehicle were operating; Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico13557845) - 2020 - CRC - 3/26/20 368 . Customer Information Whether or not the driver and passenger safety belts were buckled/fastened; . How far (if at all) the driver was depressing the accelerator and/ or brake pedal; and, . How fast the vehicle was traveling. These data can help provide a better understanding of the circumstances in which crashes and injuries occur. Note EDR data are recorded by your vehicle only if a non-trivial crash situation occurs; no data are recorded by the EDR under normal driving conditions and no personal data (e.g., name, gender, age, and crash location) are recorded. However, other parties, such as law enforcement, could combine the EDR data with the type of personally identifying data routinely acquired during a crash investigation. To read data recorded by an EDR, special equipment is required, and access to the vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties, such as law enforcement, that have the special equipment, can read the information if they have access to the vehicle or the EDR. GM will not access these data or share it with others except: with the consent of the vehicle owner or, if the vehicle is leased, with the consent of the lessee; in response to an official request by police or similar government office; as part of GM's defense of litigation through the discovery process; or, as required by law. Data that GM collects or receives may also be used for GM research needs or may be made available to others for research purposes, where a need is shown and the data is not tied to a specific vehicle or vehicle owner. OnStar If the vehicle is equipped with OnStar and has an active service plan, additional data may be collected and transmitted through the OnStar system. This includes information about the vehicle’s operation; collisions involving the vehicle; the use of the vehicle and its features, including infotainment; and the location and approximate GPS speed of the vehicle. Refer to the OnStar Terms and Conditions and Privacy Statement on the OnStar website. www.carobook.com See OnStar Additional Information 0 371. Infotainment System If the vehicle is equipped with a navigation system as part of the infotainment system, use of the system may result in the storage of destinations, addresses, telephone numbers, and other trip information.
