What Makes an Airbag Inflate?
In a deployment event, the sensing system sends anelectrical signal triggering a release of gas fromthe inflator. Gas from the inflator fills the airbag causingthe bag to break out of the cover and deploy. Theinflator, the airbag, and related hardware are all part ofthe airbag module.
Frontal airbag modules are located inside the steeringwheel and instrument panel. For vehicles withseat-mounted side impact airbags, there are airbagmodules in the side of the front seatbacks closest to thedoor. For vehicles with roof-rail airbags, there areairbag modules in the ceiling of the vehicle, near theside 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 orthe instrument panel. In moderate to severe sidecollisions, even belted occupants can contact the insideof the vehicle.
Airbags supplement the protection provided by safetybelts. Frontal airbags distribute the force of theimpact more evenly over the occupant’s upper body,stopping the occupant more gradually. Seat-mountedside impact and roof-rail airbags distribute the forceof the impact more evenly over the occupant’supper body.
But airbags would not help in many types of collisions,primarily because the occupant’s motion is nottoward those airbags. SeeWhen Should an AirbagInflate? on page 2-63for more information.
Airbags should never be regarded as anything morethan a supplement to safety belts.

What Will You See After an Airbag
Inflates?
After the frontal airbags and seat-mounted side impactairbags inflate, they quickly deflate, so quickly thatsome people may not even realize an airbag inflated.Roof-rail airbags may still be at least partially inflated forsome time after they deploy. Some components ofthe airbag module may be hot for several minutes. Forlocation of the airbag modules, seeWhat Makes anAirbag Inflate? on page 2-65.
The parts of the airbag that come into contact with youmay be warm, but not too hot to touch. There maybe some smoke and dust coming from the vents in thedeflated airbags. Airbag inflation does not preventthe driver from seeing out of the windshield or beingable to steer the vehicle, nor does it prevent people fromleaving 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 unlockthe doors, turn on the interior lamps and hazardwarning flashers, and shut off the fuel system after theairbags inflate. You can lock the doors, turn off theinterior lamps and hazard warning flashers by using thecontrols for those features.
2-66

{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 theright front passenger airbag.
•Airbags are designed to inflate only once. After an
airbag inflates, you will need some new parts forthe airbag system. If you do not get them, the airbagsystem will not be there to help protect you inanother crash. A new system will include airbagmodules and possibly other parts. The servicemanual for your vehicle covers the need to replaceother parts.
•The vehicle has a crash sensing and diagnostic
module which records information after a crash.SeeVehicle Data Recording and Privacy onpage 8-18andEvent Data Recorders on page 8-19.
•Let only qualified technicians work on the airbag
systems. Improper service can mean that anairbag system will not work properly. See yourdealer/retailer for service.
Passenger Sensing System
The vehicle has a passenger sensing system for theright front passenger position. The passenger airbagstatus indicator will be visible on the overhead consolewhen the vehicle is started.
The words ON and OFF, or the symbol for on and off,are visible during the system check. If you are usingremote start, if equipped, to start the vehicle froma distance, you may not see the system check.
United StatesCanada
2-67

When the system check is complete, either the wordON or OFF, or the symbol for on or off, will be visible.SeePassenger Airbag Status Indicator on page 4-51.
The passenger sensing system turns off the rightfront passenger frontal airbag and seat-mounted sideimpact airbag under certain conditions. The driverairbags and the roof-rail airbags are not affected by thepassenger sensing system.
The passenger sensing system works with sensors thatare part of the right front passenger seat. The sensorsare designed to detect the presence of a properly-seatedoccupant and determine if the right front passengerfrontal airbag and seat-mounted side impact airbagshould be enabled (may inflate) or not.
According to accident statistics, children are safer whenproperly secured in a rear seat in the correct childrestraint 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-facingchild restraint; a child riding in a forward-facing childseat; 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-facingchild seat in the front.” This is because the risk tothe 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 has turned
off the right front passenger frontal airbag and
seat-mounted side impact airbag (if equipped), no
system is fail-safe. No one can guarantee that an
airbag will not deploy under some unusual
circumstance, even though the airbag(s) are off.
Secure rear-facing child restraints in a rear seat,
even if the airbag(s) are 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.
2-68

The passenger sensing system is designed to turn offthe right front passenger airbag and seat-mountedside impact airbag if:
•The right front passenger seat is unoccupied.
•The system determines that an infant is present in
a rear-facing infant seat.
•The system determines that a small child is present
in a child restraint.
•The system determines that a small child is present
in a booster seat.
•A right front passenger takes his/her weight off of
the seat for a period of time.
•The right front passenger seat is occupied by a
smaller person, such as a child who has outgrownchild restraints.
•Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned off theright front passenger frontal airbag and seat-mountedside impact airbag, the off indicator will light and stay litto remind you that the airbags are off. SeePassengerAirbag Status Indicator on page 4-51.
The passenger sensing system is designed to turn on(may inflate) the right front passenger frontal airbag andseat-mounted side impact airbag anytime the systemsenses that a person of adult size is sitting properly inthe right front passenger seat.
When the passenger sensing system has allowed theairbags to be enabled, the on indicator will light and staylit to remind you that the airbags are active.
For some children who have outgrown child restraintsand for very small adults, the passenger sensing systemmay or may not turn off the right front passenger frontalairbag and seat-mounted side impact airbag, dependingupon the person’s seating posture and body build.Everyone in the vehicle who has outgrown child restraintsshould wear a safety belt properly — whether or not thereis 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. SeeAirbag Readiness Light on page 4-50
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 onindicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.
3. Remove any additional items from the seat such asblankets, cushions, seat covers, seat heaters, orseat massagers.
4. Reinstall the child restraint following the directionsprovided by the child restraint manufacturer andrefer toSecuring a Child Restraint in the Right FrontSeat Position on page 2-54.
5. If, after reinstalling the child restraint and restartingthe vehicle, the on indicator is still lit, turn thevehicle off. Then slightly recline the vehicle seatbackand adjust the seat cushion, if adjustable, tomake sure that the vehicle seatback is not pushingthe child restraint into the seat cushion.
Also make sure the child restraint is not trappedunder the vehicle head restraint. If this happens,adjust the head restraint. SeeHead Restraintson page 2-2.
6. Restart the vehicle.
If the on indicator is still lit, secure the child in thechild restraint in a rear seat position in the vehicle,and check with your dealer/retailer.
2-70

If the Off Indicator is Lit for an
Adult-Size Occupant
If a person of adult-size is sitting in the right frontpassenger seat, but the off indicator is lit, it could bebecause that person is not sitting properly in the seat.
If this happens, use the following steps to allow thesystem to detect that person and enable the right frontpassenger frontal airbag and seat-mounted sideimpact airbag:
1. Turn the vehicle off.
2. Remove any additional material from the seat, suchas blankets, cushions, seat covers, seat heaters, orseat massagers.
3. Place the seatback in the fully upright position.
4. Have the person sit upright in the seat, centered onthe seat cushion, with legs comfortably extended.
5. Restart the vehicle and have the person remain inthis position for two to three minutes after the onindicator is lit.
2-71

Additional Factors Affecting System
Operation
Safety belts help keep the passenger in position on theseat during vehicle maneuvers and braking, whichhelps the passenger sensing system maintain thepassenger airbag status. See “Safety Belts” and“Child Restraints” in the Index for additional informationabout the importance of proper restraint use.
A thick layer of additional material, such as a blanket orcushion, or aftermarket equipment such as seatcovers, seat heaters, and seat massagers can affecthow well the passenger sensing system operates.We recommend that you not use seat covers or otheraftermarket equipment except when approved by GM foryour specific vehicle. SeeAdding Equipment to YourAirbag-Equipped Vehicle on page 2-73for moreinformation about modifications that can affect how thesystem operates.
{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 Your Airbag-Equipped
Vehicle
Airbags affect how the vehicle should be serviced.There are parts of the airbag system in several placesaround the vehicle. Your dealer/retailer and theservice manual have information about servicing thevehicle and the airbag system. To purchase a servicemanual, seeService Publications Ordering Informationon page 8-17.
{WARNING:
For up to 10 seconds after the ignition 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.
