Roof-rail airbags are not intended to in ate in frontal
impacts, near-frontal impacts, rollovers, or rear impacts.
A roof-rail airbag is intended to deploy on the side of
the vehicle that is struck.
In any particular crash, no one can say whether an
airbag should have in ated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, in ation is determined by what
the vehicle hits, the angle of the impact, and how quickly
the vehicle slows down. For roof-rail airbags, deployment
is determined by the location and severity of the side
impact.
What Makes an Airbag In ate?
In a deployment event, the sensing system sends an
electrical signal triggering a release of gas from the
in ator. Gas from the in ator lls the airbag causing the
bag to break out of the cover and deploy. The in ator, the
airbag, and related hardware are all part of the airbag
module.
Frontal airbag modules are located inside the steering
wheel and instrument panel. For vehicles with roof-rail
airbags, there are airbag modules in the ceiling of the
vehicle, near the side windows that have occupant
seating positions.
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. Frontal airbags distribute the force of the
impact more evenly over the occupant’s upper body,
stopping the occupant more gradually. Roof-rail airbags
distribute the force of the impact more evenly over
the occupant’s upper body.
But airbags would not help in many types of collisions,
primarily because the occupant’s motion is not toward
those airbags. SeeWhen Should an Airbag Inflate? on
page 1-56for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.

What Will You See After an Airbag
In ates?
After the frontal airbags in ate, they quickly de ate,
so quickly that some people may not even realize an
airbag in ated. Roof-rail airbags may still be at least
partially in ated for some time after they deploy.
Some components of the airbag module may be hot
for several minutes. For location of the airbag modules,
seeWhat Makes an Airbag Inflate? on page 1-57.
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
de ated airbags. Airbag in ation 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.
{CAUTION:
When an airbag in ates, 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 in ates, 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 the interior lamps on, and turn the hazard
warning ashers on when the airbags in ate. You can
lock the doors, turn the interior lamps off, and turn the
hazard warning ashers off by using the controls for
those features.

In many crashes severe enough to in ate the airbag,
windshields are broken by vehicle deformation. Additional
windshield breakage may also occur from the right front
passenger airbag.
Airbags are designed to in ate only once. After an
airbag in ates, 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.
SeeVehicle Data Recording and Privacy on
page 7-17andEvent Data Recorders on page 7-18.
Let only quali ed technicians work on the airbag
systems. Improper service can mean that an airbag
system will not work properly. See your dealer/
retailer for service.
Passenger Sensing System
The vehicle has a passenger sensing system for the
right front passenger position. The passenger airbag
status indicator will be visible on the instrument
panel when the vehicle is started.
The words ON and OFF, or the symbol for on and off,
will be visible during the system check. If you are using
remote start to start the vehicle from a distance, if
equipped, you may not see the system check. When
the system check is complete, either the word ON or
the word OFF, or the symbol for on or off, will be visible.
SeePassenger Airbag Status Indicator on page 3-27. United States
Canada

The passenger sensing system will turn off the right
front passenger frontal airbag under certain conditions.
The driver airbag and roof-rail airbags are not affected
by the passenger sensing system.
The passenger sensing system works with sensors that
are part of the right front passenger seat. The sensors
are designed to detect the presence of a properly-seated
occupant and determine if the right front passenger
frontal airbag should be enabled (may in ate) 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.
We recommend that children be secured in a rear seat,
including: an infant or a child riding in a rear-facing
child restraint; a child riding in a forward-facing child
seat; an older child riding in a booster seat; and children,
who are large enough, using safety belts.
A label on the 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.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front passenger
airbag in ates. This is because the back of the
rear-facing child restraint would be very close to the
in ating airbag. A child in a forward-facing child
restraint can be seriously injured or killed if the right
front passenger airbag in ates and the passenger
seat is in a forward position.
Even if the passenger sensing system 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 the airbag 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 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.

The passenger sensing system is designed to turn off
the right front passenger frontal airbag if:
The right front passenger seat is unoccupied.
The system determines that an infant is present in
a child restraint.
A right front passenger takes his/her weight off of
the seat for a period of time.
Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned off the
right front passenger frontal airbag, the off indicator
will light and stay lit to remind you that the airbag is off.
SeePassenger Airbag Status Indicator on page 3-27.
The passenger sensing system is designed turn on (may
in ate) the right front passenger frontal airbag anytime
the system senses that a person of adult size is sitting
properly in the right front passenger 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, including children in child restraints,
and for very small adults, the passenger sensing system
may or may not turn off the right front 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.
{CAUTION:
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. SeeAirbag Readiness Light on page 3-26
for more information, including important safety
information.
If the On Indicator is Lit for 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 toSecuring a Child Restraint in the Right Front
Seat Position on page 1-48.
1-61
Page 66 of 402
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.
Also make sure the child restraint is not trapped
under the vehicle head restraint. If this happens,
adjust the head restraint. SeeHead Restraints
on page 1-7.
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 seating posture and body build. It is
better to secure the child restraint in a rear seat.If the Off Indicator is Lit for an
Adult-Size Occupant
If a person of adult-size is sitting in the right front
passenger seat, but the off indicator is lit, it could be
because that person is not sitting properly in the seat.
1-62
Page 67 of 402
If this happens, use the following steps to allow the
system to detect that person and enable the right front
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.
4. Have the person sit upright in the seat, centered on
the seat cushion, with legs comfortably extended.
5. 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
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 speci c
vehicle. SeeAdding Equipment to Your Airbag-Equipped
Vehicle on page 1-65for more information about
modi cations that can affect how the system operates.
A wet seat can affect the performance of the passenger
sensing system. Here is how:
The passenger sensing system may turn off the
passenger airbag when liquid is soaked into the seat.
If this happens, the off indicator will be lit, and the
airbag readiness light on the instrument panel will
also be lit.
Liquid pooled on the seat that has not soaked in
may make it more likely that the passenger sensing
system will enable (turn on) the passenger airbag
while a child restraint or child occupant is on the seat.
If the passenger airbag is turned on, the on indicator
will be lit.
1-63
Page 68 of 402
If the passenger seat gets wet, dry the seat immediately.
If the airbag readiness light is lit, do not install a child
restraint or allow anyone to occupy the seat. SeeAirbag
Readiness Light on page 3-26for important safety
information.
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.
{CAUTION:
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 Your 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/retailer 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 7-16.
{CAUTION:
For up to 10 seconds after the ignition is turned off
and the battery is disconnected, an airbag can still
in ate during improper service. You can be injured
if you are close to an airbag when it in ates. 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 quali ed to do so.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change the vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. 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, front sensors, or airbag wiring can affect
the operation of the airbag system.
In addition, the vehicle has a passenger sensing
system for the right front passenger position, which
includes sensors that are part of the passenger’s
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 alsointerfere 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). SeePassenger Sensing
System on page 1-59.

Restraint System Check
Checking the Restraint Systems
Safety Belts
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/retailer 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.
SeeSafety Belt Reminders on page 3-25for more
information.
Keep safety belts clean and dry. SeeCare of Safety
Belts on page 5-97.
Airbags
The airbag system does not need regularly scheduled
maintenance or replacement. Make sure the airbag
readiness light is working. SeeAirbag Readiness Light
on page 3-26for more information.
Notice: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 covers, have the airbag
covering and/or airbag module replaced. For the
location of the airbag modules, seeWhat Makes an
Airbag Inflate? on page 1-57. See your dealer/retailer
for service.
