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.
If the Off Indicator Is Lit for an Adult-Sized Occupant
If a person of adult size is sitting in the front outboard passenger seat, but the off indicator is lit, it could be because that person is not sitting properly in the seat or that the child restraint locking feature is engaged. If this happens, use the following steps to allow the system to detect that person and enable the front outboard passenger frontal airbag: 1. Turn the vehicle off.
2. Remove any additional material
from the seat, such as blankets, cushions, seat covers, seat heaters, or seat massagers.
3. Place the seatback in the fully
upright position.
5.
4. Have the person sit upright in the seat, centered on the seat cushion, with legs comfortably extended. If the shoulder portion of the belt is pulled out all the way, the child restraint locking feature will be engaged. This may unintentionally cause the passenger sensing system to turn the airbag off for some adult-sized occupants. If this happens, unbuckle the belt, let the belt go back all the way, and then buckle the belt again without pulling the belt out all the way.
6. Restart the vehicle and have
the person remain in this position for two to three minutes after the on indicator is lit.

{ Warning
If the front outboard passenger airbag is turned off for an adult-sized occupant, the airbag will not be able to inflate and help protect that person in a crash, resulting in an increased risk of serious injury or even death. An adult-sized occupant should not ride in the front outboard passenger seat, if the passenger airbag off indicator is lit.
Additional Factors Affecting System Operation Safety 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 “Safety Belts” and “Child Restraints” in the Index for additional information about the importance of proper restraint use.
A thick layer of additional material, such as a blanket or cushion, or aftermarket equipment such as seat covers, seat heaters, and seat massagers can affect how well the passenger sensing system operates. We recommend that you not use seat covers or other aftermarket equipment except when approved by GM for your specific vehicle. See Adding Equipment to the Airbag-Equipped Vehicle 0 72
for more information about modifications that can affect how the system operates. The on indicator may be lit if an object, such as a briefcase, handbag, grocery bag, laptop, or other electronic device, is put on an unoccupied seat. If this is not desired, remove the object from the seat.{ Warning

are close to an airbag when it inflates. Avoid yellow connectors. They are probably part of the airbag system. Be sure to follow proper service procedures, and make sure the person performing work for you is qualified to do so.
Adding Equipment to the Airbag-Equipped Vehicle Adding accessories that change the vehicle's frame, bumper system, height, front end, or side sheet metal, may keep the airbag system from working properly. The operation of the airbag system can also be affected by changing or moving any parts of the front seats, safety belts, the airbag sensing and diagnostic module, steering wheel, instrument panel, roof-rail airbag modules, ceiling headliner or pillar garnish trim, overhead console, front sensors, side impact sensors, or airbag wiring.
Your dealer and the service manual have information about the location of the airbag sensors, sensing and diagnostic module, and airbag wiring. In addition, the vehicle may have a passenger sensing system for the front outboard passenger position, which includes sensors that are part of the passenger seat. The passenger sensing system may not operate properly if the original seat trim is replaced with non-GM covers, upholstery, or trim; or with GM covers, upholstery, or trim designed for a different vehicle. Any object, such as an aftermarket seat heater or a comfort-enhancing pad or device, installed under or on top of the seat fabric, could also interfere with the operation of the passenger sensing system. This could either prevent proper deployment of the passenger airbag(s) or prevent the passenger sensing system from properly turning off the passenger airbag(s). See Passenger Sensing System 0 67.
If the vehicle has rollover roof-rail airbags, see Different Size Tires and Wheels 0 311 for additional important information. If a snow plow is added to the vehicle, the airbags should still work properly. The airbag systems were designed to work properly under a wide range of conditions, including snow plowing with vehicles that have the optional snow plow prep package (RPO VYU). Do not change or defeat the snow plow's “tripping mechanism.” If you do, it can damage the snow plow and the vehicle, and may cause an airbag deployment. If you have to modify your vehicle because you have a disability and you have questions about whether the modifications will affect the vehicle's airbag system, or if you have questions about whether the airbag system will be affected if the vehicle is modified for any other reason, call Customer Assistance. See Customer Assistance Offices 0 365.

Airbag System Check The airbag system does not need regularly scheduled maintenance or replacement. Make sure the airbag readiness light is working. See Airbag Readiness Light 0 113.
Caution
If an airbag covering is damaged, opened, or broken, the airbag may not work properly. Do not open or break the airbag coverings. If there are any opened or broken airbag coverings, have the airbag covering and/or airbag module replaced. For the location of the airbags, see Where Are the Airbags? 0 63. See your dealer for service.
Replacing Airbag System Parts after a Crash { Warning
A crash can damage the airbag systems in the vehicle. A damaged airbag system may not work properly and may not protect you and your passenger(s) in a crash, resulting in serious injury or even death. To help make sure the airbag systems are working properly after a crash, have them inspected and any necessary replacements made as soon as possible.
If an airbag inflates, you will need to replace airbag system parts. See your dealer for service. If the airbag readiness light stays on after the vehicle is started or comes on when you are driving, the airbag system may not work properly. Have the vehicle serviced right away. See Airbag Readiness Light 0 113.

wear safety 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.
Also see “Rear Safety Belt Comfort Guides” under Lap-Shoulder Belt 0 56. 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 safety belts properly.
GMC Sierra Denali Owner Manual (GMNA-Localizing-U.S./Canada/Mexico- 9234761) - 2016 - crc - 7/24/15
{ Warning
Never allow a child to wear the safety 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.

{ 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 safety belts.
Every time infants and young children ride in vehicles, they should have the protection provided by appropriate child restraints. Neither
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.

the vehicle's safety 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 should be secured in an appropriate restraint.
{ Warning
Children who are up against, or very close to, any airbag when it inflates can be seriously injured or killed. Never put a rear-facing child restraint in the front outboard seat. Secure a rear-facing child restraint in a rear seat. It is also better to secure a forward-facing child restraint in a rear seat. If you must secure a forward-facing child restraint in the front outboard seat, always move the front passenger seat as far back as it will go.
Q: What are the different types of
add-on child restraints?
A: Add-on child restraints, which are purchased by the vehicle owner, are available in four basic types. Selection of a particular restraint should take into consideration not only the child's weight, height, and age but also whether or not the restraint will be compatible with the motor vehicle in which it will be used. For most basic types of child restraints, there are many different models available. When purchasing a child restraint, be sure it is designed to be used in a motor vehicle. If it is, the
GMC Sierra Denali Owner Manual (GMNA-Localizing-U.S./Canada/Mexico- 9234761) - 2016 - crc - 7/24/15
restraint will have a label saying that it meets federal motor vehicle safety standards. The restraint manufacturer instructions that come with the restraint state the weight and height limitations for a particular child restraint. In addition, there are many kinds of restraints available for children with special needs.
{ Warning
To reduce the risk of neck and head injury in a crash, infants and toddlers should be secured in a rear-facing child restraint until age two, or until they reach the maximum height and weight limits of their child restraint.
{ Warning
A young child's hip bones are still so small that the vehicle's regular safety belt may not remain low on the hip bones, as it should. Instead, it may settle up around the child's abdomen. In a crash, the belt would apply force on a body area that is unprotected by any bony structure. This alone could cause serious or fatal injuries. To reduce the risk of serious or fatal injuries during a crash, young children should always be secured in appropriate child restraints.

Keep in mind that an unsecured child restraint can move around in a collision or sudden stop and injure people in the vehicle. Be sure to properly secure any child restraint in the vehicle — even when no child is in it. In some areas of the United States and Canada, Certified Child Passenger Safety Technicians (CPSTs) are available to inspect and demonstrate how to correctly use and install child restraints. In the U.S., refer to the National Highway Traffic Safety Administration (NHTSA) website to locate the nearest child safety seat inspection station. For CPST availability in Canada, check with Transport Canada or the Provincial Ministry of Transportation office.

Securing the Child Within the Child Restraint
{ Warning
{ Warning
A child can be seriously injured or killed in a crash if the child is not properly secured in the child restraint. Secure the child properly following the instructions that came with that child restraint.
Where to Put the Restraint According to accident statistics, children and infants are safer when properly restrained in a child restraint system or infant restraint system secured in a rear seating position. Whenever possible, children aged 12 and under should be secured in a rear seating position. Never put a rear-facing child seat in the front. This is because the risk to the rear-facing child is so great if the airbag deploys.
A child in a rear-facing child restraint can be seriously injured or killed if the front outboard passenger airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag. A child in a forward-facing child restraint can be seriously injured or killed if the front outboard passenger airbag inflates and the passenger seat is in a forward position. The vehicle may have a passenger sensing system which is designed to turn off the front outboard passenger frontal airbag under certain conditions. Even if the passenger sensing system, if equipped, has turned off the front outboard passenger frontal airbag, no system is fail-safe. No one can guarantee that an airbag will not deploy

under some unusual circumstance, even though it is turned off. Secure rear-facing child restraints in a rear seat, even if the airbag is off. If you secure a forward-facing child restraint in the front outboard seat, always move the front passenger seat as far back as it will go. It is better to secure the child restraint in a rear seat. See Passenger Sensing System 0 67 for additional information.
When securing a child restraint in a rear seating position, study the instructions that came with the child restraint to make sure it is compatible with this vehicle. Child restraints and booster seats vary considerably in size, and some may fit in certain seating positions better than others.
Depending on where you place the child restraint and the size of the child restraint, you may not be able to access adjacent safety belt assemblies 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 safety belt. Wherever a child restraint is installed, be sure to secure the child restraint properly. Keep in mind that an unsecured child restraint can move around in a collision or sudden stop and injure people in the vehicle. Be sure to properly secure any child restraint in the vehicle — even when no child is in it.
Lower Anchors and Tethers for Children (LATCH System) The LATCH system secures a child restraint during driving or in a crash. LATCH attachments on the child
restraint are used to attach the child restraint to the anchors in the vehicle. 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 safety belts. Do not use both the safety belts and the LATCH anchorage system to secure a rear-facing or forward-facing child seat. Booster seats use the vehicle’s safety belts to secure the child in the booster seat. If the manufacturer recommends that the booster seat be secured with the LATCH system, this can be done as long as the booster seat can be positioned properly and there is no interference with the proper positioning of the lap-shoulder belt on the child.
GMC Sierra Denali Owner Manual (GMNA-Localizing-U.S./Canada/Mexico- 9234761) - 2016 - crc - 7/24/15
Make sure to follow the instructions that came with the child restraint, and also the instructions in this manual. When installing a child restraint with a top tether, you must also use either the lower anchors or the safety belts to properly secure the child restraint. A child restraint must never be attached using only the top tether. The LATCH anchorage system can be used until the combined weight of the child plus the child restraint is 29.5 kg (65 lbs). Use the safety belt alone instead of the LATCH anchorage system once the combined weight is more than 29.5 kg (65 lbs). The following explains how to attach a child restraint with these attachments in the vehicle. Not all vehicle seating positions or child restraints have lower anchors and attachments or top tether anchors and attachments. In this case, the safety belt must be used (with top tether where available) to secure the child restraint. See

To assist in locating the lower anchors on crew cab models, each seating position with lower anchors has two labels near the crease between the seatback and the seat cushion.
Rear Seat
i (Top Tether Anchor) : Seating positions with top tether anchors.
The top tether anchors are the loops near the top of the seatback for each rear seating position. These loops will be used to route the top tether through, as well as to secure the top tether to the vehicle. Be sure to use the anchor (loop) on the same side of the vehicle as the seating position where the child restraint will be placed. Be sure to read the following instructions to properly install a child restraint using these loops. Do not secure a child restraint in a position without a top tether anchor if a national or local law requires that the top tether be attached, or if the instructions that come with the child restraint say that the top tether must be attached. According to accident statistics, children and infants are safer when properly restrained in a child restraint system or infant restraint system secured in a rear seating position. See Where to Put the Restraint 0 79 for additional information.

Headrest Removal and Reinstallation
Removing Rear Headrests For outboard rear seating positions, if the child restraint cannot be installed properly with the head rest in place, the headrest may be removed. See your dealer for assistance with removal and store the removed headrests in a secure place. When the child restraint is removed, reinstall the headrest before the seating position is used.
Reinstalling Rear Headrests
To reinstall the headrest: 1.
Insert the headrest posts into the holes in the top of the seatback with the longer chrome plated post toward the driver side of the vehicle.
2. Push the headrest all the way
down until it contacts the top of the seatback.
Replacing LATCH System Parts After a Crash { Warning
A crash can damage the LATCH system in the vehicle. A damaged LATCH system may not properly secure the child restraint, resulting in serious injury or even death in a crash. To help make sure the LATCH system is working properly after a crash, see your dealer to have the system inspected and any necessary replacements made as soon as possible.
If the vehicle has the LATCH system and it was being used during a crash, new LATCH system parts may be needed. New parts and repairs may be necessary even if the LATCH system was not being used at the time of the crash.
GMC Sierra Denali Owner Manual (GMNA-Localizing-U.S./Canada/Mexico- 9234761) - 2016 - crc - 7/24/15
Securing Child Restraints (Rear Seat) When securing a child restraint in a rear seating position, study the instructions that came with the child restraint to make sure it is compatible with this vehicle. If the child restraint has the LATCH system, see Lower Anchors and Tethers for Children (LATCH System) 0 80 for how and where to install the child restraint using LATCH. If you secure a child restraint using a safety belt and it uses a top tether, see Lower Anchors and Tethers for Children (LATCH System) 0 80 for top tether anchor locations. Do not secure a child restraint in a position without a top tether anchor if a national or local law requires that the top tether be anchored, or if the instructions that come with the child restraint say that the top strap must be anchored.
In Canada, the law requires that forward-facing child restraints have a top tether, and that the tether be attached. If the child restraint or vehicle seat position does not have the LATCH system, you will be using the safety belt to secure the child restraint in this position. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say. If more than one child restraint needs to be installed in the rear seat, be sure to read Where to Put the Restraint 0 79. If the child restraint manufacturer recommends using a top tether, attach and tighten the top tether to the top tether anchor. Refer to the instructions that came with the child restraint and see Lower Anchors and Tethers for Children (LATCH System) 0 80. 1. Put the child restraint on

If the child restraint has a top tether, follow the child restraint manufacturer's instructions regarding the use of the top tether. See Lower Anchors and Tethers for Children (LATCH System) 0 80.
7. Before placing a child in the
child restraint, make sure it is securely held in place. To check, grasp the child restraint at the safety belt path and attempt to move it side to side and back and forth. When the child restraint is properly installed, there should be no more than 2.5 cm (1 in) of movement.
To remove the child restraint, unbuckle the vehicle safety belt and let it return to the stowed position. If the top tether is attached to a top tether anchor, disconnect it. For outboard rear seating positions, if the child restraint cannot be installed properly with the headrest in place, the headrest may be removed. See your dealer for assistance with removal, and store

Securing Child Restraints (Front Passenger Seat)
Light-Duty Vehicles This vehicle has airbags. A rear seat is a safer place to secure a forward-facing child restraint. See Where to Put the Restraint 0 79. In addition, the vehicle has a passenger sensing system which is designed to turn off the front outboard passenger frontal airbag under certain conditions. See Passenger Sensing System 0 67
and Passenger Airbag Status Indicator 0 113 for more information on this, including important safety information.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 deploys.
{ Warning
A child in a rear-facing child restraint can be seriously injured or killed if the front outboard 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 front outboard passenger frontal airbag inflates and the passenger seat is in a forward position. Even if the passenger sensing system has turned off the front outboard passenger frontal airbag, no system is fail-safe. No one can guarantee that an airbag (Continued)

Warning (Continued)
will not deploy under some unusual circumstance, even though it is turned off. Secure rear-facing child restraints in a rear seat, even if the airbag is off. If you secure a forward-facing child restraint in the front seat, always move the front passenger seat as far back as it will go. It is better to secure the child restraint in a rear seat. See Passenger Sensing System 0 67 for additional information.
If a child restraint uses a top tether, see Lower Anchors and Tethers for Children (LATCH System) 0 80 for top tether anchor locations. Do not secure a child seat in a position without a top tether anchor if a national or local law requires that the top tether be anchored, or if the instructions that come with the child restraint say that the top strap must be anchored.

In Canada, the law requires that forward-facing child restraints have a top tether, and that the tether be attached. When using the lap-shoulder belt to secure the child restraint in this position, follow the instructions that came with the child restraint and the following instructions: 1. Move the seat as far back as it
will go before securing the forward-facing child restraint. When the passenger sensing system has turned off the front outboard passenger frontal airbag, the off indicator in the passenger airbag status indicator should light and stay lit when you start the vehicle. See Passenger Airbag Status Indicator 0 113.
