Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. Your dealer/retailer and the service
manual have information about servicing your vehicle
and the airbag system. To purchase a service manual,
seeService Publications Ordering Information on
page 7-17.
{CAUTION:
For up to 10 seconds after the ignition is
turned off and the battery is disconnected, an
airbag can still inate during improper service.
You can be injured if you are close to an
airbag when it inates. 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 qualied 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 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,
the inside review mirror, front sensors, or airbag
wiring can affect the operation of the airbag system.
In addition, your vehicle has 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 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,
1-56

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 1-51.
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.Q:Because I have a disability, I have to get my
vehicle modied. How can I nd out whether
this will affect my airbag system?
A: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. See
Customer Satisfaction Procedure on page 7-2.
Your dealer/retailer and the service manual have
information about the location of the airbag sensors,
sensing and diagnostic module and airbag wiring.

Hatch
{CAUTION:
It can be dangerous to drive with the hatch/
trunk lid open because carbon monoxide (CO)
gas can come into your vehicle. You can not see
or smell CO. It can cause unconsciousness and
even death. If you must drive with the hatch/
trunk lid open or if electrical wiring or other
cable connections must pass through the seal
between the body and the hatch/trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. SeeDual Automatic
Climate Control System on page 3-26.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-35.Notice:Closing the hatch/trunk lid forcefully or
from the sides can cause damage to the glass, the
defogger or the weather stripping. Be sure objects
will t in the hatch/trunk area before closing the
hatch/trunk lid. When closing the hatch/trunk
lid, gently pull down from the center.
Notice:Do not store heavy or sharp objects in
the rear storage compartments located in the
hatch/trunk area. If you do, the objects could
damage the underbody.

Airbag Readiness Light
There is an airbag readiness light on the instrument
panel cluster, which shows the airbag symbol. The
system checks the airbag’s electrical system for
malfunctions. The light indicates if there is an electrical
problem. The system check includes the airbag
sensor, the pretensioners, the airbag modules, the
wiring and the crash sensing and diagnostic module.
For more information on the airbag system, seeAirbag
System on page 1-43.
This light comes on when
the vehicle is started,
and ashes for a
few seconds. The light
should go out when
the system is ready.
If the airbag readiness light stays on after the vehicle is
started or comes on while driving, the airbag system
may not work properly. Have your vehicle serviced
right away.{CAUTION:
If the airbag readiness light stays on after you
start your vehicle, it means the airbag system
may not be working properly. The airbags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help
avoid injury to yourself or others, have your
vehicle serviced right away.
The airbag readiness light should ash for a few seconds
when the engine is started. If the light does not come on
then, have it xed immediately. If there is a problem with
the airbag system, an airbag Driver Information Center
(DIC) message may also come on. SeeDIC Warnings
and Messages on page 3-57for more information.

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer/retailer
rst. Some electrical equipment can damage your
vehicle and the damage would not be covered by
your warranty. Some add-on electrical equipment can
keep other components from working as they should.
Add-on equipment can drain your vehicle’s battery, even
if your vehicle is not operating.
Your vehicle has an airbag system. Before attempting to
add anything electrical to your vehicle, seeServicing
Your Airbag-Equipped Vehicle on page 1-56.
Headlamp Wiring
The headlamp wiring is protected by fuses in the fuse
block. An electrical overload will cause the lamps to turn
off. If this happens, have your headlamp wiring
checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools.
If the overload is caused by some electrical problem,
have it xed.
Power Windows and Other Power
Options
Circuit breakers protect the power seats, power
windows, and other power accessories. When the
current load is too heavy, the circuit breaker opens and
closes, protecting the circuit until the problem is xed
or goes away.
5-99

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of J-Case fuses,
mini-fuses and circuit breakers. This greatly reduces the
chance of res caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
If you ever have a problem on the road and do not have
a spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle
that you can get along without – like the radio or
cigarette lighter – and use its fuse, if it is the correct
amperage. Replace it as soon as you can.
Instrument Panel Fuse Block
The instrument panel fuse block is located on the
passenger side of the vehicle, under the instrument
panel and under the toe-board.
Remove the carpet and toe-board covering to access
the fuse block by pulling at the top of each corner of the
panel. Open the fuse block cover to access the fuses.
You can remove fuses using the fuse puller.
