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, the
inside rearview mirror, 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
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 1-27.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 12-1.
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.
SeeCustomer Satisfaction
Procedure on page 12-1.

In addition, your dealer/retailer
and the service manual have
information about the location of
the airbag sensors, sensing
and diagnostic module and
airbag wiring.
Airbag System Check
The airbag system does not need
regularly scheduled maintenance
or replacement. Make sure the
airbag readiness light is working.
SeeAirbag Readiness Light
on page 4-13for 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 1-25. See your
dealer/retailer for service.

Airbag Readiness Light
There is an airbag readiness
light which shows the airbag symbol.
The system checks the airbag’s
electrical system for malfunctions.
The light tells you 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

or comes on when you are
driving, your airbag system may not
work properly. Have your vehicle
serviced right away.
{CAUTION
If the airbag readiness light stays
on after the vehicle is started or
comes on while driving, it means
the airbag system might not be
working properly. The airbags in
the vehicle might not inate in a
crash, or they could even inate
without a crash. To help avoid
injury, have the vehicle serviced
right away.If there is a problem with the airbag
system, a message may also
come on. SeeDIC Warnings and
Messages on page 4-26for
more information.

Electrical System
Add-On Electrical
Equipment
Notice:Do not add anything
electrical to the vehicle unless you
check with your dealer/retailer
rst. Some electrical equipment
can damage the vehicle and the
damage would not be covered by
the vehicle’s warranty. Some
add-on electrical equipment can
keep other components from
working as they should.
Add-on equipment can drain the
vehicle battery, even if the vehicle
is not operating.
The vehicle has an airbag system.
Before attempting to add anything
electrical to the vehicle, see
Servicing Your Airbag-Equipped
Vehicle on page 1-31.
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 the
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 in the fuse block
protect the 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.
Instrument Panel Fuse
Block
The instrument panel fuse block is
located on the end of the instrument
panel, on the driver side of the
vehicle. To access the fuses, open
the fuse panel door by pulling out.
To reinstall the door, push the door
back into its original location.
