{WARNING
For up to 10 seconds after the
ignition is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. 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 qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Q: Is there anything I might addto 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, overhead console, front
sensors, side impact sensors,
rollover sensor 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 proper deployment 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 3‑33.

page 5‑11 for 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

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 3‑26.
The airbag readiness light comes on
and stays on for several seconds
when the vehicle is started. Then
the light goes out.
{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.
Passenger Airbag Status
Indicator
The vehicle has a passenger
sensing system. See Passenger
Sensing System on page 3‑33 for
important safety information. The
overhead console has a passenger
airbag status indicator.

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 on page 10‑40. It can be used
to easily remove fuses from the fuse
block.
