modules, ceiling or pillar garnish
trim, overhead console, front
sensors, side impact sensors,
or airbag wiring.
Your dealer and the service manual
have information about the location
of the airbag sensors, sensing and
diagnostic module, and airbag
wiring.
In addition, the vehicle has a
passenger sensing system for the
front outboard 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 properlyturning off the passenger airbag(s).
See
Passenger Sensing
System 065.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires
and Wheels 0246 for additional
important information.

airbag system will be affected if the
vehicle is modified for any other
reason, call Customer Assistance.

Electrical System
Fuses
The wiring circuits in the vehicle are
protected from short circuits by
fuses. This greatly reduces the
chance of damage 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
to replace a bad fuse with a new
one of the identical size and rating.
Replace a bad fuse with a new one
of the identical size and rating.
If there is a problem on the road and
a fuse needs to be replaced, the
same amperage fuse can be
borrowed. Choose some feature of
the vehicle that is not needed to use
and replace it as soon as possible.
There are two fuse blocks in the
vehicle: one in the engine
compartment and one in the
instrument panel.There is a fuse puller located in the
engine compartment fuse block.
See
Engine Compartment Fuse
Block 0226. It can be used to easily
remove fuses from the fuse block.
Engine Compartment
Fuse Block
To remove the fuse block cover,
squeeze the clips on the cover and
lift it straight up. See Engine
Compartment Overview 0201.
Caution
Spilling liquid on any electrical
component on the vehicle may
damage it. Always keep the
