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,
ceiling headliner or pillar
garnish trim, front sensors, side
impact sensors, rolloversensor module, 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 properdeployment of the passenger
airbag(s) or prevent the
passenger sensing system from
properly turning off the
passenger airbag(s). See
Passenger Sensing System on
page 1-52.

Restraint System
Check
Checking the Restraint
Systems
Safety Belts
Now and then, check the safety belt
reminder light, safety belts,
buckles, latch plates, retractors, and
anchorages are all working
properly.
Look for any other loose or
damaged safety belt system parts
that might keep a safety belt system
from doing its job. See your
dealer/retailer to have it repaired.
Torn or frayed safety belts may not
protect you in a crash. They can
rip apart under impact forces.

connector can be plugged into a
seven-pin universal heavy-duty
trailer connector available through
your dealer/retailer.The seven-wire harness contains
the following trailer circuits:Yellow: Left Stop/Turn Signal
Dark Green: Right Stop/Turn
Signal
Brown: Taillamps
Black: Ground
Light Green: Back-up Lamps
Red/Black: Battery Feed
Dark Blue: Trailer Brake*
*The fuse for this circuit is installed
in the underhood electrical center,
but the wires are not connected.

Windshield Wiper Fuses
The windshield wiper motor is
protected by a circuit breaker and a
fuse. If the motor overheats due
to heavy snow or ice, 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.
Fuses and Circuit
Breakers
The wiring circuits in your vehicle are
protected from short circuits by
a combination of fuses, circuit
breakers and fusible thermal links.
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.
Fuses of the same amperage can be
temporarily borrowed from another
fuse location, if a fuse goes out.
Replace the fuse as soon as
you can.
Instrument Panel Fuse
Block
The instrument panel fuse block is
located under the instrument
panel on the passenger side of the
vehicle. Pull down on the cover
to access the fuse block.
