You will be using the lap-shoulder belt to secure the
child restraint in this position. SeeTop Strap on
page 1-57if your child restraint has one. 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.
1. Your vehicle has a right front passenger’s frontal air
bag. SeePassenger Sensing System on page 1-79.
General Motors recommends that rear-facing
child restraints be secured in a rear seat, even if
the air bag is off. If your child restraint is
forward-facing, move the seat as far back as it will
go before securing the child restraint in this
seat. SeePower Seats on page 1-3.
When the passenger sensing system has turned off
the right front passenger’s frontal air bag, the off
indicator in the passenger air bag status indicator
should light and stay lit when you turn the ignition to
RUN or START. SeePassenger Airbag Status
Indicator on page 3-32.
2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle’s safety belt through or
around the restraint. The child restraint instructions
will show you how.4. Buckle the belt. Make sure the release button is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.

5. Pull the rest of the shoulder belt all the way out of
the retractor to set the lock.6. To tighten the belt, push down on the child restraint,
pull the shoulder portion of the belt to tighten the lap
portion of the belt and feed the shoulder belt back
into the retractor. If you are using a forward-facing
child restraint, you may nd it helpful to use your
knee to push down on the child restraint as you
tighten the belt. You should not be able to pull more
of the belt from the retractor once the lock has
been set.

7. Push and pull the child restraint in different
directions to be sure it is secure.
8. If your vehicle has the passenger sensing system
and the air bag is off, the off indicator will be lit and
stay lit in the inside rearview mirror when the key
is turned to RUN or START.
If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove the child
restraint from the vehicle and reinstall the child restraint.
If after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the child
restraint into the seat cushion. If this happens, slightly
recline the vehicle’s seatback and adjust the seat
cushion if possible. Also make sure the child restraint is
not trapped under the vehicle head restraint. If this
happens, adjust the head restraint.
If the on indicator is still lit, secure the child in the child
restraint in a rear seat position in the vehicle and
check with your dealer.
To remove the child restraint, just unbuckle the vehicle’s
safety belt and let it go back all the way. The safety
belt will move freely again and be ready to work for an
adult or larger child passenger.Airbag System
Your vehicle has airbags — a frontal airbag for the
driver and another frontal airbag for the right front
passenger. Your vehicle may also have side impact
airbags. Side impact airbags are available for the driver
and right front passenger.
If your vehicle has a side impact airbag for the driver
and/or the right front passenger, the words AIR BAG will
appear on the airbag covering on the side of the
seatback closest to the door.

Frontal airbags are designed to help reduce the risk of
injury from the force of an inating frontal airbag.
But these airbags must inate very quickly to do their
job and comply with federal regulations.
Here are the most important things to know about the
airbag system:
{CAUTION:
You can be severely injured or killed in a crash
if you are not wearing your safety belt — even
if you have airbags. Wearing your safety belt
during a crash helps reduce your chance of
hitting things inside the vehicle or being
ejected from it. Airbags are designed to work
with safety belts but do not replace them.
CAUTION: (Continued)
CAUTION: (Continued)
Frontal airbags for the driver and right front
passenger are designed to deploy only in
moderate to severe frontal and near frontal
crashes. They are not designed to inate in
rollover, rear or low-speed frontal crashes, or in
many side crashes. And, for some unrestrained
occupants, frontal airbags may provide less
protection in frontal crashes than more forceful
airbags have provided in the past.
Side impact airbags for the driver and right front
passenger are designed to inate only in
moderate to severe crashes where something
hits the side of your vehicle. They are not
designed to inate in frontal, in rollover or in
rear crashes.
Everyone in your vehicle should wear a safety
belt properly — whether or not there is an
airbag for that person.
1-71

{CAUTION:
Both frontal and side impact airbags inate
with great force, faster than the blink of an
eye. If you are too close to an inating airbag,
as you would be if you were leaning forward, it
could seriously injure you. Safety belts help
keep you in position for airbag ination before
and during a crash. Always wear your safety
belt, even with frontal airbags. The driver
should sit as far back as possible while still
maintaining control of the vehicle. Front
occupants should not lean on or sleep against
the door.
{CAUTION:
Anyone who is up against, or very close to,
any airbag when it inates can be seriously
injured or killed. Airbags plus lap-shoulder
belts offer the best protection for adults, but
not for young children and infants. Neither the
vehicle’s safety belt system nor its airbag
system is designed for them. Young children
and infants need the protection that a child
restraint system can provide. Always secure
children properly in your vehicle. To read how,
seeOlder Children on page 1-47orInfants and
Young Children on page 1-50.
1-72

Your vehicle may or may not have a side impact airbag.
SeeAirbag System on page 1-70. Side impact airbags
are designed to inate in moderate to severe side
crashes. A side impact airbag will inate if the crash
severity is above the system’s designed “threshold
level.” The threshold level can vary with specic vehicle
design. Side impact airbags are not designed to
inate in frontal or near-frontal impacts, rollovers or rear
impacts, because ination would not likely help the
occupant. A side impact airbag will only deploy on the
side of the vehicle that is struck.
In any particular crash, no one can say whether an
airbag should have inated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, ination is determined by
the angle of the impact and how quickly the vehicle
slows down in frontal and near-frontal impacts. For side
impact airbags, ination is determined by the location
and severity of the impact.
The airbag system is designed to work properly under a
wide range of conditions, including off-road usage.
Observe safe driving speeds, especially on rough
terrain. As always, wear your safety belt. SeeOperating
Your All-Wheel-Drive Vehicle Off Paved Roads on
page 4-16for tips on off-road driving.What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag sensing
system detects that the vehicle is in a crash. For both
frontal and side impact airbags, the sensing system
triggers a release of gas from the inator, which inates
the airbag. The inator, the airbag and related hardware
are all part of the airbag modules. Frontal airbag modules
are located inside the steering wheel and instrument
panel. For vehicles with side impact airbags, the airbag
modules are located in the seatback closest to the
driver’s and/or right front passenger’s door.
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. The airbag supplements the protection
provided by safety belts. Airbags distribute the force of
the impact more evenly over the occupant’s upper body,
stopping the occupant more gradually. But the frontal
airbags would not help you in many types of collisions,
including rollovers, rear impacts, and many side impacts,
primarily because an occupant’s motion is not toward the
airbag. Side impact airbags would not help you in many
types of collisions, including frontal or near frontal
collisions, rollovers, and rear impacts, primarily because
an occupant’s motion is not toward those airbags.
1-77

Airbags should never be regarded as anything more than
a supplement to safety belts, and then only in moderate
to severe frontal or near-frontal collisions for the driver’s
and right front passenger’s frontal airbags, and only in
moderate to severe side collisions for vehicles with a
driver’s and right front passenger’s side impact airbag.
What Will You See After an Airbag
Inates?
After the airbag inates, it quickly deates, so quickly
that some people may not even realize the airbag
inated. Some components of the airbag module will be
hot for a short time. These components include the
steering wheel hub for the driver’s frontal airbag and the
instrument panel for the right front passenger’s frontal
airbag. For vehicles with side impact airbags, the side of
the seatback closest to the driver’s and/or right front
passenger’s door will be hot. The parts of the bag that
come into contact with you may be warm, but not
too hot to touch. There will be some smoke and dust
coming from the vents in the deated airbags.
Airbag ination does not prevent the driver from seeing
or being able to steer the vehicle, nor does it stop
people from leaving the vehicle.
{CAUTION:
When an airbag inates, there is 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
can not get out of the vehicle after an airbag
inates, 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.
In many crashes severe enough to inate an airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger airbag.
Airbags are designed to inate only once. After an
airbag inates, you will need some new parts for your
airbag system. If you do not get them, the air bag
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 your
vehicle covers the need to replace other parts.

The passenger sensing system will turn off the right
front passenger’s frontal airbag under certain conditions.
The driver’s airbag and the side airbags are not part
of the passenger sensing system.The passenger sensing system works with sensors that
are part of the right front passenger’s seat and safety
belt. The sensors are designed to detect the presence of
a properly-seated occupant and determine if the
passenger’s frontal airbag should be enabled (may
inate) or not.
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
General Motors recommends that child restraints
be secured in a rear seat, including an infant riding in a
rear-facing infant seat, a child riding in a forward-facing
child seat and an older child riding in a booster seat.
Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun visor
says, “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. Passenger Airbag Status Indicator – United States

If after reinstalling the child restraint and restarting the
vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the child
restraint into the seat cushion. If this happens, slightly
recline the vehicle’s seatback and adjust the seat
cushion if possible. Also make sure the child restraint is
not trapped under the vehicle head restraint. If this
happens, adjust the head restraint.
If the on indicator is still lit, secure the child in the child
restraint in a rear seat position in the vehicle and
check with your dealer.
The passenger sensing system is designed to enable
(may inate) the right front passenger’s frontal
airbag anytime the system senses that a person of adult
size is sitting properly in the right front passenger’s
seat. When the passenger sensing system has allowed
the airbag to be enabled, the on indicator will light
and stay lit to remind you that the airbag is active.
For some children who have outgrown child restraints
and for very small adults, the passenger sensing system
may or may not turn off the right front passenger’s
frontal airbag, depending upon the person’s seating
posture and body build. Everyone in your vehicle who
has outgrown child restraints should wear a safety
belt properly — whether or not there is an airbag for
that person.If a person of adult-size is sitting in the right front
passenger’s seat, but the off indicator is lit, it could be
because that person is not sitting properly in the seat. If
this happens, turn the vehicle off and ask the person to
place the seatback in the fully upright position, then sit
upright in the seat, centered on the seat cushion, with the
person’s legs comfortably extended. Restart the vehicle
and have the person remain in this position for about two
minutes. This will allow the system to detect that person
and then enable the passenger’s airbag.

Q:Because I have a disability, I have to get my
vehicle modied. How can I nd out whether
this will affect my advanced airbag system?
A:Changing or moving any parts of the front seats,
safety belts, the airbag sensing and diagnostic
module (located under the driver’s seat), or
the inside rearview mirror can affect the operation
of the advanced airbag system. If you have
questions, call Customer Assistance. The phone
numbers and addresses for Customer Assistance
are in Step Two of the Customer Satisfaction
Procedure in this manual. SeeCustomer
Satisfaction Procedure on page 7-2.
Restraint System Check
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, 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.
Also look for any opened or broken airbag covers, and
have them repaired or replaced. (The airbag system
does not need regular maintenance.)
