Airbag System
The vehicle has the following airbags:
A frontal airbag for the driver.
A frontal airbag for the right front passenger.
The vehicle may have the following airbags:
A roof-rail airbag for the driver and the passenger
seated directly behind the driver.
A roof-rail airbag for the right front passenger and
the person seated directly behind the right front
passenger.
All of the airbags in the vehicle will have the word
AIRBAG embossed in the trim or on an attached label
near the deployment opening.
For frontal airbags, the word AIRBAG will appear on the
middle part of the steering wheel for the driver and
on the instrument panel for the right front passenger.
With roof-rail airbags, the word AIRBAG will appear
along the headliner 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 inating bag, all airbags must inate
very quickly to do their job.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. Airbags are designed to work with
safety belts, but do not replace them. Also, airbags
are not designed to deploy in every crash. In some
crashes safety belts are your only restraint. See
When Should an Airbag Inflate? on page 1-77.
Wearing your safety belt during a crash helps
reduce your chance of hitting things inside the
vehicle or being ejected from it. Airbags are
“supplemental restraints” to the safety belts.
Everyone in your vehicle should wear a safety belt
properly — whether or not there is an airbag for
that person.
1-73

{CAUTION:
Airbags inate with great force, faster than the blink
of an eye. Anyone who is up against, or very close
to, any airbag when it inates can be seriously
injured or killed. Do not sit unnecessarily close to
the airbag, as you would be if you were sitting on
the edge of your seat or leaning forward. Safety
belts help keep you in position before and during a
crash. Always wear your 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
roof-rail airbags.
{CAUTION:
Children who are up against, or very close to, any
airbag when it inates can be seriously injured or
killed. Airbags plus lap-shoulder belts offer
protection for adults and older children, 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 1-38or
Infants and Young Children on page 1-41.
There is an airbag
readiness light on the
instrument panel 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. SeeAirbag Readiness Light on page 3-37
for more information.
1-74

Where Are the Airbags?
The driver’s airbag is in the middle of the steering
wheel.The right front passenger’s airbag is in the instrument
panel on the passenger’s side.
1-75

What Makes an Airbag Inate?
In a deployment event, the sensing system sends an
electrical signal triggering a release of gas from the
inator. Gas from the inator lls the airbag causing the
bag to break out of the cover and deploy. The inator, 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.Rollover capable roof-rail airbags are designed to help
contain the head and chest of occupants in the outboard
seating positions in the rst 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. SeeWhen Should an Airbag
Inflate? on page 1-77for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.
What Will You See After an Airbag
Inates?
After the frontal airbags inate, they quickly deate, so
quickly that some people may not even realize an airbag
inated. Roof-rail airbags may still be at least partially
inated 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 1-79.

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 your 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, overhead console, front sensors,
rollover sensor module, or airbag wiring can affect
the operation of the airbag system.
In addition, your vehicle may have a passenger
sensing system for the right front passenger’s
position, which includes sensors that are part of the
passenger’s seat. The passenger sensing systemmay 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). SeePassenger Sensing
System on page 1-84.
If you have any questions about this, you should
contact Customer Assistance before you modify
your vehicle. 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.
If your vehicle has rollover roof-rail airbags, see
Different Size Tires and Wheels on page 5-86
for additional important information.

PASS-Key®III+ Electronic
Immobilizer Operation
Your vehicle has PASS-Key®III+ (Personalized
Automotive Security System) theft-deterrent system.
PASS-Key
®III+ is a passive theft-deterrent system.
The system is automatically armed when the key
is removed from the ignition.
The system is automatically disarmed when the key
is turned to ON/RUN, ACC/ACCESSORY or START
from the LOCK/OFF position.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
When the PASS-Key
®III+ system senses that someone
is using the wrong key, it prevents the vehicle from
starting. Anyone using a trial-and-error method to start
the vehicle will be discouraged because of the high
number of electrical key codes.
If the engine does not start and the security light on
the instrument panel cluster comes on when trying to
start the vehicle, there may be a problem with your
theft-deterrent system. Turn the ignition off and try again.
2-20

The steering can bind with the wheels turned off center.
If this happens, move the steering wheel from right
to left while turning the key to ACC/ACCESSORY.
If this doesn’t work, then the vehicle needs service.
Notice:Using a tool to force the key to turn in
the ignition could cause damage to the switch or
break the key. Use the correct key, make sure it
is all the way in, and turn it only with your hand.
If the key cannot be turned by hand, see your
dealer/retailer.
B (ACC/ACCESSORY):This position lets things like the
radio and the windshield wipers operate while the engine
is off. Use this position if the vehicle must be pushed or
towed.
C (ON/RUN):This position can be used to operate the
electrical accessories and to display some instrument
panel cluster warning and indicator lights. The switch
stays in this position when the engine is running.
The transmission is also unlocked in this position on
automatic transmission vehicles.
If you leave the key in the ACC/ACCESSORY or ON/
RUN position with the engine off, the battery could be
drained. You may not be able to start the vehicle if the
battery is allowed to drain for an extended period of time.D (START):This is the position that starts the engine.
When the engine starts, release the key. The ignition
switch returns to ON/RUN for driving.
A warning tone will sound when the driver door is
opened, the ignition is in ACC/ACCESSORY or
LOCK/OFF and the key is in the ignition.
Retained Accessory Power (RAP)
The following vehicle accessories can be used for up to
10 minutes after the engine is turned off:
Audio System
Power Windows
OnStar®System (if equipped)
Sunroof (if equipped)
These features work when the key is in ON/RUN or
ACC/ACCESSORY. Once the key is turned from
ON/RUN to LOCK/OFF, the windows and sunroof
continue to work up to 10 minutes until any door
is opened. The radio continues to work for up to
10 minutes or until the driver door is opened.
