are more likely to be seriously injured or killed. Do not allow passengers to ride in any area of the vehicle that is not equipped with seats and safety belts. Always wear a safety belt, and check that all passenger(s) are restrained properly too.

This vehicle has indicators as a reminder to buckle the safety belts. See Safety Belt Reminders on page 5-17.

Why Safety Belts Work

When riding in a vehicle, you travel as fast as the vehicle does. If the vehicle stops suddenly, you keep going until something stops you. It could be the windshield, the instrument panel, or the safety belts! When you wear a safety belt, you and the vehicle slow down together. There is more time to stop because you stop over a longer distance and, when worn properly, your strongest bones take the forces from the

safety belts. That is why wearing safety belts makes such good sense. Questions and Answers About Safety Belts Q: Will I be trapped in the vehicle after a crash if I am wearing a safety belt?

A: You could be — whether you are

wearing a safety belt or not. Your chance of being conscious during and after a crash, so you can unbuckle and get out, is much greater if you are belted.

Q: If my vehicle has airbags, why

should I have to wear safety belts?

A: Airbags are supplemental

systems only; so they work with safety belts — not instead of them. Whether or not an airbag is provided, all occupants still have to buckle up to get the most protection.

Also, in nearly all states and in all Canadian provinces, the law requires wearing safety belts.

How to Wear Safety Belts Properly This section is only for people of adult size. There are special things to know about safety belts and children. And there are different rules for smaller children and infants. If a child will be riding in the vehicle, see Older Children on page 3-38 or Infants and Young Children on page 3-40. Follow those rules for everyone's protection. It is very important for all occupants to buckle up. Statistics show that unbelted people are hurt more often in crashes than those who are wearing safety belts. There are important things to know about wearing a safety belt properly.

. Sit up straight and always keep

your feet on the floor in front of you.

. Always use the correct buckle

for your seating position.

. Wear the lap part of the belt low

and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones and you would be less likely to slide under the lap belt. If you slid under it, the belt would apply force on your abdomen. This could cause serious or even fatal injuries.

Seats and Restraints

. Wear the shoulder belt over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces. The shoulder belt locks if there is a sudden stop or crash.

{ Warning

You can be seriously injured, or even killed, by not wearing your safety belt properly. . Never allow the lap or

shoulder belt to become loose or twisted.

. Never wear the shoulder belt

under both arms or behind your back.

. Never route the lap or shoulder belt over an armrest.

Lap-Shoulder Belt If the vehicle is a regular cab, then all seating positions in the vehicle have a lap-shoulder belt. If the vehicle is a double or crew cab, then all seating positions in the vehicle have a lap-shoulder belt except for the center front passenger position (if equipped), which has a lap belt. See Lap Belt on page 3-19 for more information. The following instructions explain how to wear a lap-shoulder belt properly. 1. Adjust the seat, if the seat is adjustable, so you can sit up straight. To see how, see “Seats” in the Index.

2. Pick up the latch plate and pull the belt across you. Do not let it get twisted. The lap-shoulder belt may lock if you pull the belt across you very quickly. If this happens, let the belt go back slightly to unlock it. Then pull the belt across you more slowly. If the shoulder portion of a passenger belt is pulled out all the way, the child restraint locking feature may be engaged. If this happens, let the belt go back all the way and start again. Engaging the child restraint locking feature may affect the passenger sensing system, if equipped. See Passenger Sensing System on page 3-31
for more information.

If equipped with a shoulder belt height adjuster, move it to the height that is right for you. See “Shoulder Belt Height Adjuster” later in this section for instructions on use and important safety information.

For the driver and front outboard seating positions on light duty vehicles and the center front seating position on all vehicles (if equipped), if the webbing locks in the latch plate before it reaches the buckle, tilt the latch plate flat to unlock.

3. Push the latch plate into the

buckle until it clicks. Pull up on the latch plate to make sure it is secure. If the belt is not long enough, see Safety Belt Extender on page 3-20. Position the release button on the buckle so that the safety belt could be quickly unbuckled if necessary.

5. To make the lap part tight, pull

up on the shoulder belt.

Adjust the height so the shoulder portion of the belt is on the shoulder and not falling off of it. The belt should be close to, but not contacting, the neck. Improper shoulder belt height adjustment could reduce the effectiveness of the safety belt in a crash. See How to Wear Safety Belts Properly on page 3-13.

To unlatch the belt, push the button on the buckle. The belt should return to its stowed position. Before a door is closed, be sure the safety belt is out of the way. If a door is slammed against a safety belt, damage can occur to both the safety belt and the vehicle. Shoulder Belt Height Adjuster The vehicle has a shoulder belt height adjuster for the driver and front outboard passenger.

Push down on the release button to move the height adjuster to the desired position.

Move the adjuster up by pushing up on the shoulder belt guide. After the adjuster is set to the desired position, try to move it down without pushing the release button to make sure it has locked into position. Safety Belt Pretensioners This vehicle has safety belt pretensioners for front outboard occupants. Although the safety belt pretensioners cannot be seen, they are part of the safety belt assembly. They can help tighten the safety belts during the early stages of a moderate to severe frontal, near frontal, or rear crash if the threshold conditions for pretensioner activation are met. And, if your vehicle has side impact airbags, safety belt pretensioners can help tighten the safety belts in a side crash. If the vehicle has rollover roof-rail airbags, safety belt pretensioners can help tighten the safety belts in a rollover event.

2. Attach the adjustable comfort

guide to the anchor loop by threading the hook through the loop.

3. Place the guide over the belt,

and insert the two edges of the belt into the slots of the guide.

Pretensioners work only once. If the pretensioners activate in a crash, they will need to be replaced, and the vehicle's safety belt system will probably need other new parts. See Replacing Safety Belt System Parts after a Crash on page 3-21. Rear Safety Belt Comfort Guides Rear safety belt comfort guides may provide added safety belt comfort for older children who have outgrown booster seats and for some adults. When installed on a shoulder belt, the comfort guide positions the shoulder belt away from the neck and head. This vehicle may have an adjustable comfort guide. Additional comfort guides are available through your dealer.

To install the adjustable comfort guide to the seatback and the safety belt:

1. Locate the anchorage loop on

the rear outboard seatback, near the top.

6. Adjust the guide so the shoulder

portion of the belt is on the shoulder and not falling off of it. The belt should be close to, but not contacting, the neck. Improper comfort guide adjustment could reduce the effectiveness of the safety belt in a crash.

{ Warning

A safety belt that is not properly worn may not provide the protection needed in a crash. The person wearing the belt could be seriously injured. The shoulder belt should go over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces.

4. Be sure that the belt is not twisted and it lies flat. The elastic cord must be under the belt and the guide on top.

5. The elastic cord on the comfort

guide is adjustable. Make it longer or shorter by squeezing both ends of the plastic adjuster and pulling on the elastic cord or the guide.

7. Buckle and position the safety belt as described previously in this section. Make sure that the shoulder belt crosses the shoulder.

To remove and store the comfort guide, squeeze the belt edges together so that the safety belt can be removed from the guide. Unhook the guide from the loop on the seat. Store the guide in a convenient place like the glove box for the next time it is needed.

The best way to protect the fetus is to protect the mother. When a safety 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 safety belts effective is wearing them properly.

Lap Belt This section is only for the lap belt. To learn how to wear a lap-shoulder belt, see Lap-Shoulder Belt on page 3-14. The vehicle may have a center seating position with a lap safety belt. The lap safety belt does not have a retractor.

Safety Belt Use During Pregnancy Safety belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they do not wear safety belts.

A pregnant woman should wear a lap-shoulder belt, and the lap portion should be worn as low as possible, below the rounding, throughout the pregnancy.

To make the belt longer, tilt the latch plate and pull it along the belt. Buckle, position, and release it the same way as the lap part of a lap-shoulder belt.

Safety Belt Extender If the vehicle's safety belt will fasten around you, you should use it. But if a safety 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 seats. To wear it, attach it to the regular safety belt. See the instruction sheet that comes with the extender.

Safety System Check Now and then, check that the safety belt reminder light, safety belts, buckles, latch plates, retractors, and anchorages are all working properly. Look for any other loose or damaged safety belt system parts that might keep a safety belt system from doing its job. See your dealer

to have it repaired. Torn or frayed safety belts may not protect you in a crash. They can rip apart under impact forces. If a belt is torn or frayed, get a new one right away. Make sure the safety belt reminder light is working. See Safety Belt Reminders on page 5-17. Keep safety belts clean and dry. See Safety Belt Care on page 3-20.

Safety Belt Care Keep belts clean and dry. { Warning

Do not bleach or dye safety belts. It may severely weaken them. In a crash, they might not be able to provide adequate protection. Clean safety belts only with mild soap and lukewarm water.

To make the belt shorter, pull its free end as shown until the belt is snug. If the belt is not long enough, see Safety Belt Extender on page 3-20. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if necessary.

See your dealer to have the safety belt assemblies inspected or replaced. New parts and repairs may be necessary even if the safety belt system was not being used at the time of the crash. Have the safety belt pretensioners checked if the vehicle has been in a crash, or if the airbag readiness light stays on after you start the vehicle or while you are driving. See Airbag Readiness Light on page 5-18.

Replacing Safety Belt System Parts after a Crash

{ Warning

A crash can damage the safety belt system in the vehicle. A damaged safety belt system may not properly protect the person using it, resulting in serious injury or even death in a crash. To help make sure the safety belt systems are working properly after a crash, have them inspected and any necessary replacements made as soon as possible.

After a minor crash, replacement of safety belts may not be necessary. But the safety belt assemblies that were used during any crash may have been stressed or damaged.

Seats and Restraints

For frontal airbags, the word AIRBAG is on the center of the steering wheel for the driver and on the instrument panel for the front outboard passenger. For seat-mounted side impact airbags, the word AIRBAG is on the seatback closest to the door. For roof-rail airbags, the word AIRBAG is on the ceiling or trim. Airbags are designed to supplement the protection provided by safety belts. Even though today's airbags are also designed to help reduce the risk of injury from the force of an inflating bag, all airbags must inflate very quickly to do their job.

Here are the most important things to know about the airbag system:

{ Warning

{ Warning

You can be severely injured or killed in a crash if you are not wearing your safety belt, even with airbags. Airbags are designed to work with safety belts, not replace them. Also, airbags are not designed to inflate in every crash. In some crashes safety belts are the only restraint. See When Should an Airbag Inflate? on page 3-25. Wearing your safety belt during a crash helps reduce the chance of hitting things inside the vehicle or being ejected from it. Airbags are “supplemental restraints” to the safety belts. Everyone in the vehicle should wear a safety belt properly, whether or not there is an airbag for that person.

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. Safety belts help keep you in position before and during a crash. Always wear a safety belt, even with airbags. The driver should sit as far back as possible while still maintaining control of the vehicle. 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.

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 on page 3-38 or Infants and Young Children on page 3-40.

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 on page 5-18 for more information.

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.

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.

When Should an Airbag Inflate? This vehicle is equipped with airbags. See Airbag System on page 3-21. 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 which help the airbag system determine the severity of the impact. Deployment thresholds can vary with specific vehicle design. Frontal airbags are designed to inflate in moderate to severe frontal or near frontal crashes to help reduce the potential for severe injuries, mainly to the driver's or front outboard passenger's head and chest. Whether the frontal airbags will or should inflate is not based primarily on how fast the vehicle is traveling.

It depends on what is hit, the direction of the impact, and how quickly the vehicle slows down. Frontal airbags may inflate at different crash speeds depending on whether the vehicle hits an object straight on or at an angle, and whether the object is fixed or moving, rigid or deformable, narrow or wide. Frontal airbags are not intended to inflate during vehicle rollovers, in rear impacts, or in many side impacts. In addition, if the GVWR (Gross Vehicle Weight Rating) is at or below 3 855 kg (8,500 lb), the vehicle has advanced technology frontal airbags. You can find the GVWR on the Certification/Tire label on the center pillar of the vehicle. See Vehicle Load Limits on page 9-16 for more information. Advanced technology frontal airbags adjust the restraint according to crash severity. Vehicles with advanced technology frontal airbags

have a seat position sensor that enables the sensing system to monitor the position of the driver seat. The seat position sensor provides information that is used to adjust the deployment of the driver frontal airbag. If the GVWR is at or below 4 536 kg (10,000 lb), the vehicle has seat-mounted side impact airbags. Vehicles with a GVWR above 4 536 kg (10,000 lb) may or may not have seat-mounted side impact airbags. Seat-mounted side impact airbags, if equipped, are designed to inflate in moderate to severe side crashes depending on the location of the impact. Seat-mounted side impact airbags are not designed to inflate in frontal impacts, near frontal impacts, rollovers, or rear impacts. A seat-mounted side impact airbag is designed to inflate on the side of the vehicle that is struck. Vehicles with a GVWR at or below 3 855 kg (8,500 lb) have roof-rail airbags. These roof-rail airbags are designed to inflate in moderate to

Seats and Restraints

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. The roof-rail airbags are not designed to inflate in rear impacts. Both roof-rail airbags will inflate when either side of the vehicle is struck or if the sensing system predicts that the vehicle is about to roll over on its side, or in a severe frontal impact. Vehicles with a GVWR above 3 855 kg (8,500 lb) up to and including 4 536 kg (10,000 lb) also have roof-rail airbags. These roof-rail airbags are designed to inflate in moderate to severe side crashes depending on the location of the impact. Both roof-rail airbags will inflate when either side of the vehicle is struck. In addition, these roof-rail airbags are designed to inflate in a severe frontal impact. The roof-rail airbags are also rollover capable except on models sold as an incomplete vehicle with the pickup box removed. If the

roof-rail airbags are rollover capable, both roof-rail airbags will also inflate if the sensing system predicts that the vehicle is about to roll over on its side. The roof-rail airbags are not designed to inflate in rear impacts. Vehicles with a GVWR above 4 536 kg (10,000 lb) may or may not be equipped with roof-rail airbags. These roof-rail airbags, if equipped, are designed to inflate in moderate to severe side crashes depending on the location of the impact. Both roof-rail airbags will inflate when either side of the vehicle is struck. In addition, these roof-rail airbags are designed to inflate in a severe frontal impact. If the vehicle has single rear wheels and has a factory-installed pickup box and roof-rail airbags, the roof-rail airbags are rollover capable. If the vehicle has dual rear wheels, or is sold as an incomplete vehicle, as a chassis cab, or with the pickup box removed, and has roof-rail airbags, the roof-rail airbags are not rollover

capable. If the airbags are rollover capable, both roof-rail airbags will also inflate if the sensing system predicts that the vehicle is about to roll over on its side. The roof-rail airbags are not designed to inflate in rear impacts. 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? on page 3-23.

(GMNA-Localizing-U.S./Canada/Mexico-

Black plate (27,1)

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 safety belts by distributing the force of the impact more evenly over the occupant's body. Rollover capable roof-rail airbags are designed to help contain the head and chest of occupants in the outboard seating positions in the first and second rows. The rollover capable roof-rail airbags are designed to help reduce the risk of full or partial ejection in rollover events, although no system can prevent all such ejections.

But airbags would not help in many types of collisions, primarily because the occupant's motion is not toward those airbags. See When Should an Airbag Inflate? on page 3-25. Airbags should never be regarded as anything more than a supplement to safety belts.

What Will You See after an Airbag Inflates? After the frontal airbags and seat-mounted side impact airbags inflate, they quickly deflate, so quickly that some people may not even realize an airbag 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? on page 3-23. The parts of the airbag that come into contact with you may be warm, but not too hot to touch. There may

Seats and Restraints

3-27

be some smoke and dust coming from the vents in the deflated airbags. Airbag inflation does not prevent the driver from seeing out of the windshield or being able to steer the vehicle, nor does it prevent people from leaving the vehicle.

{ Warning

When an airbag inflates, there may be dust in the air. This dust could cause breathing problems for people with a history of asthma or other breathing trouble. To avoid this, everyone in the vehicle should get out as soon as it is safe to do so. If you have breathing problems but cannot get out of the vehicle after an airbag inflates, then get fresh air by opening a window or a door. If you experience breathing problems following an airbag deployment, you should seek medical attention.

The vehicle has a feature that may automatically unlock the doors, turn on the interior lamps, turn on the hazard warning flashers, and shut off the fuel system after the airbags inflate. You can lock the doors, turn off the interior lamps, and turn off the hazard warning flashers by using the controls for those features.

{ Warning

A crash severe enough to inflate the airbags may have also damaged important functions in the vehicle, such as the fuel system, brake and steering systems, etc. Even if the vehicle appears to be drivable after a moderate crash, there may be concealed damage that could make it difficult to safely operate the vehicle. Use caution if you should attempt to restart the engine after a crash has occurred.

In many crashes severe enough to inflate the airbag, windshields are broken by vehicle deformation. Additional windshield breakage may also occur from the front outboard passenger airbag. . Airbags are designed to inflate

only once. After an airbag inflates, you will need some new parts for the airbag system. If you do not get them, the airbag system will not be there to help protect you in another crash. A new system will include airbag modules and possibly other parts. The service manual for the vehicle covers the need to replace other parts. The vehicle has a crash sensing and diagnostic module which records information after a crash. See Vehicle Data Recording and Privacy on page 13-14 and Event Data Recorders on page 13-14.

Let only qualified technicians work on the airbag systems. Improper service can mean that an airbag system will not work properly. See your dealer for service.

Airbag On-Off Switch If the passenger side instrument panel endcap has the switch pictured in the following illustration, the vehicle has an airbag on-off switch that you can use to manually turn on or off the front outboard passenger frontal airbag. See Instrument Panel on page 1-2.

Medical Condition. A passenger has a medical condition which, according to his or her physician: . Causes the passenger airbag to

pose a special risk for the passenger; and

. Makes the potential harm from

the passenger airbag in a crash greater than the potential harm from turning off the airbag and allowing the passenger, even if belted, to hit the instrument panel or windshield in a crash.

The infant has a medical condition which, according to the infant's physician, makes it necessary for the infant to ride in the front seat so that the driver can constantly monitor the child's condition.

Child age 1 to 12. A child age 1 to 12 must ride in the front seat because: . My vehicle has no rear seat; . Although children ages 1 to 12

ride in the rear seat(s) whenever possible, children ages 1 to 12
sometimes must ride in the front because no space is available in the rear seat(s) of my vehicle; or The child has a medical condition which, according to the child's physician, makes it necessary for the child to ride in the front seat so that the driver can constantly monitor the child's condition.

If the vehicle does not have an airbag on-off switch, it may have a passenger sensing system. See Passenger Sensing System on page 3-31. This switch should only be turned to the off position if the person in the front outboard passenger position is a member of a passenger risk group identified by the national government as follows:

Infant. An infant (less than 1 year old) must ride in the front seat because: . My vehicle has no rear seat; . My vehicle has a rear seat too

small to accommodate a rear-facing infant seat; or

Passenger Sensing System If the vehicle has one of the following indicators, then the vehicle has a passenger sensing system for the front outboard passenger position, unless there is an airbag on-off switch on the instrument panel endcap. If there is an airbag on-off switch, the vehicle does not have a passenger sensing system. See Airbag On-Off Switch on page 3-28 for more information.

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 safety belt. The sensors are designed to detect the presence of a properly seated occupant and determine if the front outboard passenger frontal airbag should be allowed to inflate or not. According to accident statistics, children are safer when properly secured in a rear seat in the correct child restraint for their weight and size. Whenever possible, children age 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.

Seats and Restraints

{ 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 inflate under some unusual circumstance, even though the airbag is 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 outboard passenger seat, always move the seat as far back as it will go. It is better to secure the child restraint in a rear seat.

If the vehicle does not have a rear seat that will accommodate a rear-facing child restraint, a rear-facing child restraint should not be installed in the vehicle, even if the airbag is off. The passenger sensing system is designed to turn off the front outboard passenger frontal airbag if:

The front outboard passenger seat is unoccupied. The system determines an infant is present in a child restraint.

. A front outboard passenger

takes his/her weight off of the seat for a period of time. 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 on page 5-20. 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.

If the On Indicator Is Lit for a Child Restraint The passenger sensing system is designed to turn off the front outboard passenger frontal airbag if the system determines that an infant is present in a child restraint. If a child restraint has been installed and the on indicator is lit: 1. Turn the vehicle off. 2. Remove the child restraint from

the vehicle.

3. Remove any additional items

from the seat such as blankets, cushions, seat covers, seat heaters, or seat massagers.

4. Reinstall the child restraint

following the directions provided by the child restraint manufacturer and refer to Securing Child Restraints (Center Front Seat) on page 3-58 or Securing Child Restraints (Front Outboard Passenger Seat) on page 3-58
or Securing Child Restraints (Rear Seat) on page 3-68. Even if the child restraint is equipped with a safety belt lock-off, make sure the safety belt retractor is locked by pulling the shoulder belt all the way out of the retractor before tightening the safety belt. When the retractor lock is set, the belt can be tightened but not pulled out of the retractor.

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 safety belt properly — whether or not there is an airbag for that person. { Warning

If the airbag readiness light ever comes on and stays on, it means that something may be wrong with the airbag system. To help avoid injury to yourself or others, have the vehicle serviced right away. See Airbag Readiness Light on page 5-18 for more information, including important safety information.

If, after reinstalling the child restraint and restarting the vehicle, the on indicator is still lit, turn the vehicle off. Then slightly recline the vehicle seatback and adjust the seat cushion, if adjustable, to make sure that the vehicle seatback is not pushing the child restraint into the seat cushion. Also make sure the child restraint is not trapped under the vehicle head restraint. If this happens, adjust the head restraint. See Head Restraints on page 3-2.

6. Restart the vehicle. The passenger sensing system may or may not turn off the airbag for a child in a child restraint depending upon the child’s size. It is better to secure 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.

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 on page 3-36 for more information about modifications that can affect how the system operates. The on indicator may be lit if an object, such as a briefcase, handbag, grocery bag, laptop, or other electronic device, is put on an unoccupied seat. If this is not desired, remove the object from the seat.

{ Warning

Stowing of articles under the passenger seat or between the passenger seat cushion and seatback may interfere with the proper operation of the passenger sensing system.

Servicing the Airbag-Equipped Vehicle Airbags affect how the vehicle should be serviced. There are parts of the airbag system in several places around the vehicle. Your dealer and the service manual have information about servicing the vehicle and the airbag system. To purchase a service manual, see Service Publications Ordering Information on page 13-11.

{ 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.

Seats and Restraints

{ Warning

For up to 10 seconds after the vehicle is turned off and the battery is disconnected, an airbag can still inflate during improper service. You can be injured if you are close to an airbag when it inflates. Avoid yellow connectors. They are probably part of the airbag system. Be sure to follow proper service procedures, and make sure the person performing work for you is qualified to do so.

Adding Equipment to the Airbag-Equipped Vehicle Adding accessories that change the vehicle's frame, bumper system, height, front end, or side sheet metal, may keep the airbag system from working properly. The operation of the airbag system can also be affected by changing 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 on page 3-31. If the vehicle has rollover roof-rail airbags, see Different Size Tires and Wheels on page 10-72 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.

Child Restraints

Older Children

Older children who have outgrown booster seats should wear the vehicle safety belts.

The manufacturer instructions that come with the booster seat state the weight and height limitations for that booster. Use a booster seat with a lap-shoulder belt until the child passes the fit test below: . Sit all the way back on the seat.

Do the knees bend at the seat edge? If yes, continue. If no, return to the booster seat.

. Buckle the lap-shoulder belt.

Does the shoulder belt rest on the shoulder? If yes, continue. If no, try using the rear safety belt comfort guide. See “Rear Safety Belt Comfort Guides” under Lap-Shoulder Belt on page 3-14. If the shoulder belt still does not rest on the shoulder, then return to the booster seat.

. Does the lap belt fit low and

snug on the hips, touching the thighs? If yes, continue. If no, return to the booster seat.

. Can proper safety belt fit be

maintained for the length of the trip? If yes, continue. If no, return to the booster seat.

Q: What is the proper way to

wear 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 on page 3-14. According to accident statistics, children are safer when properly restrained in a rear seating position.

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.

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.

{ Warning

Never allow more than one child to wear the same safety belt. The safety belt cannot properly spread the impact forces. In a crash, they can be crushed together and seriously injured. A safety belt must be used by only one person at a time.

{ 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

Seats and Restraints

Infants and Young Children Everyone in a vehicle needs protection! This includes infants and all other children. Neither the distance traveled nor the age and size of the traveler changes the need, for everyone, to use safety restraints. In fact, the law in every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle.

{ Warning

Children can be seriously injured or strangled if a shoulder belt is wrapped around their neck and the safety belt continues to tighten. 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 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 right front 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 right front

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 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 during a crash, infants need complete support. In a crash, if an infant is in a rear-facing child restraint, the crash forces can be distributed across the strongest part of an infant's body, the back and shoulders. Infants should always be secured in rear-facing child restraints.

{ 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

Forward-Facing Child Seat

A forward-facing child seat provides restraint for the child's body with the harness.

Rear-Facing Infant Seat

A rear-facing infant seat 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.

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 safety 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 restraint systems 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) on page 3-46.

Children can be endangered in a crash if the child restraint is not properly secured in the vehicle. When securing an add-on child restraint, refer to the instructions that come with the restraint which may be on the restraint itself or in a booklet, or both, and to this manual. The child restraint instructions are important, so if they are not available, obtain a replacement copy from the manufacturer. Keep in mind that an unsecured child restraint can move around in a collision or sudden stop and injure people in the vehicle. Be sure to properly secure any child restraint in the vehicle — even when no child is in it. In some areas of the United States and Canada, Certified Child Passenger Safety Technicians (CPSTs) are available to inspect and demonstrate how to correctly use and install child restraints. In the U.S., refer to the National Highway Traffic Safety

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 age 12 and under should be secured in a rear seating position. If a child restraint is secured in the front outboard passenger seat, and the vehicle has a switch on the passenger side instrument panel endcap to manually turn off the front outboard passenger airbag, see Airbag On-Off Switch on page 3-28
and Securing Child Restraints (Center Front Seat) on page 3-58 or Securing Child Restraints (Front Outboard Passenger Seat) on page 3-58 or Securing Child Restraints (Rear Seat) on page 3-68
for more information, 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 right 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 right front passenger airbag inflates and the passenger seat is in a forward position. Even if the passenger sensing system or airbag switch has turned off the right 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.

If the vehicle does not have a rear seat that will accommodate a rear-facing child restraint, a rear-facing child restraint should not be installed in the vehicle, even if the airbag is off. 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 your vehicle — even when no child is in it.

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 right 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.

{ Warning

A child in a child restraint in the center front seat can be badly injured or killed by the frontal airbags if they inflate. Never secure a child restraint in the center front seat. It is always better to secure a child restraint in a rear seat.

Do not use child restraints in the center front seat position. When securing a child restraint in a rear seating position, study the instructions that came with your 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. Always make sure the child restraint is properly secured. 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.
