Maintaining Your Airbag System
WARNING!
²Modifications to any part of the airbag system could
cause it to fail when you need it. You could be
injured if the airbag system is not there to protect
you. Do not modify the components or wiring,
including adding any kind of badges or stickers to
the steering wheel hub trim cover or the upper right
side of the instrument panel. Do not modify the
front bumper or vehicle body structure.
²You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolsters.
²It is dangerous to try to repair any part of the
airbag system yourself. Be sure to tell anyone who
works on your vehicle that it has an airbag system.NOTE:

designed to be maintenance free. If any of the following
occurs, have an authorized dealer service the system
promptly:

ignition switch is first turned on.
²Remains on after the 2.5 to 8 second interval.
²Flickers, or comes on and remains on for any period of
time while driving.

related gauges are not working, the airbag control mod-
ule may also be disabled. The airbags may not be ready
to inflate for your protection. Promptly check the fuse

SAFETY TIPS
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO)
follow the safety tips below.
²Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for a extended period. If the vehicle is
stopped in an open area with engine running for more
than a short period, adjust the ventilation system to
force fresh, outside air into the vehicle.
²Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
²Always run the climate control in panel or floor mode
when driving with any windows open, even if only
slightly, to help keep fresh air circulating inside ve-
hicle. Otherwise poisonous gases could be drawn into
the vehicle.
Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.

Seat belt assemblies must be replaced after an accident if
they have been damaged (bent retractor, torn webbing,
etc.). If there is any question regarding belt or retractor
condition, replace the belt.
Airbag Warning Light
The light should come on and remain on for 6 to 8
seconds as a bulb check when the ignition switch is first
turned on. If the bulb is not lit during starting, have it
replaced. If the light stays on or comes on while driving,
have the system checked by an authorized dealer.
Defrosters
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is inoper-
able.
Safety Checks You Should Make Outside The
Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect for tread cuts or sidewall
cracks. Check wheel nuts for tightness and tires (includ-
ing spare) for proper pressure.
Lights
Have someone observe the operation of all exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
coolant, oil or other fluid leaks. Also, if gasoline fumes
are detected, the cause should be located and corrected
immediately.
