Adding Equipment to
the 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, side impact
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 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 2-28.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.
Q:Because I have a disability,
I have to get my vehicle
modi ed. 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.
Seats and Restraints 2-33
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 4-17for 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 2-26. See your dealer/retailer
for service.
Replacing Airbag System
Parts After a Crash
{WARNING
A crash can damage the
airbag systems in your vehicle.
A damaged airbag system may not
work properly and may not protect
you and your passenger(s) in a
crash, resulting in serious injury or
even death. To help make sure
your airbag systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as
possible.If an airbag inflates, you will need
to replace airbag system parts.
See your dealer/retailer for service.
If the airbag readiness light stays
on after the vehicle is started
or comes on when you are driving,
the airbag system may not work
properly. Have the vehicle serviced
right away. SeeAirbag Readiness
Light on page 4-17for more
information.
2-34 Seats and Restraints
If the passenger safety belt is
buckled, neither the chime nor the
light comes on.
The front passenger safety belt
warning light and chime may turn
on if an object is put on the
seat such as a briefcase, handbag,
grocery bag, laptop or other
electronic device. To turn off the
warning light and or chime, remove
the object from the seat or buckle
the safety belt
Airbag Readiness Light
This light shows 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 2-21.
The airbag readiness light comes on
and stays on for several seconds
when the vehicle is started. Then the
light goes out.
If it stays on after the vehicle has
been started or comes on while
driving, the airbag system may not
work properly. Have the vehicle
serviced right away.
{WARNING
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 inflate in a
crash, or they could even inflate
without a crash. To help avoid
injury, have the vehicle serviced
right away.

Electrical System
Electrical System
Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load
is too heavy, the circuit breaker
opens and closes, protecting the
circuit until the current load returns
to normal or the problem is fixed.
This greatly reduces the chance of
circuit overload and fire caused by
electrical problems.
Fuses and circuit breakers protect
the following in the vehicle:
•Headlamp Wiring
•Windshield Wiper Motor
•Power Windows and other Power
Accessories
Vehicle Care 9-41
Headlamp Wiring
An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have
the headlamp wiring checked right
away if the lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.
Although the circuit is protected
from electrical overload, overload
due to heavy snow or ice, may
cause wiper linkage damage.
Always clear ice and heavy snow
from the windshield before using
the windshield wipers.
If the overload is caused by an
electrical problem and not snow
or ice, be sure to get it fixed.
Fuses and Circuit
Breakers
The wiring circuits in the vehicle
are protected from short circuits by
a combination of fuses and circuit
breakers. This greatly reduces the
chance of damage caused by
electrical problems.
To check a fuse, look at the
silver-colored band inside the fuse.
If the band is broken or melted,
replace the fuse. Be sure to replace
a bad fuse with a new one of the
identical size and rating.
Fuses of the same amperage
can be temporarily borrowed from
another fuse location, if a fuse goes
out. Replace the fuse as soon as
possible.
To identify and check fuses, circuit
breakers, and relays, seeEngine
Compartment Fuse Block on
page 9-42,Instrument Panel Fuse
Block on page 9-45, andRear
Compartment Fuse Block on
page 9-46.
Engine Compartment
Fuse Block
To remove the hinged fuse block
cover, press the clip at the front of
the cover, and swing it up.
Notice:Spilling liquid on any
electrical components on the
vehicle may damage it. Always
keep the covers on any electrical
component.
