WARNINGS AND CAUTIONS
This manual containsWARNINGSagainst operating
procedures which could result in an accident or bodily
injury. It also containsCAUTIONSagainst procedures
which could result in damage to your vehicle. If you do
not read this entire manual you may miss important
information. Observe all Warnings and Cautions.
VEHICLE IDENTIFICATION NUMBER
The vehicle identification number (VIN) is found on a
stamped plate located on the left front corner of the
instrument panel pad, visible from outside of vehicle
through windshield. This number also appears on the
Automobile Information Disclosure Label affixed to a
window on your vehicle. Save this label for a convenient
record of your vehicle identification number and optional
equipment.

WARNING!
Using a seat belt extender when not needed can
increase the risk of injury in a collision. Only use
when the seat belt is not long enough when it is
worn low and snug, and in the recommended seating
positions. Remove and stow the seat belt extender
when not needed.
Driver And Front Passenger Supplemental
Restraint Systems (SRS) Ð Airbags
This vehicle has front airbags for both the driver and
front passenger as a supplement to the seat belt restraint
system. The driver's front airbag is mounted in the center
of the steering wheel. The passenger's front airbag is
mounted in the instrument panel, above the glove com-
partment. The words SRS/AIRBAG are embossed on the
airbag covers.
NOTE:The front airbags are certified to the Federal
regulations that allow less forceful deployment.
NOTE:Airbag covers may not be obvious in the
interior trim; but they will open to allow airbag deploy-
ment.
WARNING!
Do not put anything on or around the front airbag
covers or attempt to manually open them. You may
damage the airbags and you could be injured be-
cause the airbags are not there to protect you. These
protective covers for the airbag cushions are de-
signed to open only when the airbags are inflating.
22 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
²Relying on the airbags alone could lead to more
severe injuries in a collision. The airbags work
with your seat belt to restrain you properly. In
some collisions the airbags won't deploy at all.
Always wear your seat belts even though you
have airbags.
²Being too close to the steering wheel or instru-
ment panel during airbag deployment could cause
serious injury. Airbags need room to inflate. Sit
back, comfortably extending your arms to reach
the steering wheel or instrument panel.
Airbag System Components
The airbag system consists of the following:
²Airbag Control Module (ACM)
²Airbag Warning Light
²Driver Airbag
²Passenger Airbag
²Steering Wheel And Column
²Instrument Panel
²Crash Sensor
²Interconnecting Wiring
²Knee Impact Bolsters
²Passenger Airbag ON/OFF Switch (If Equipped)
How The Airbag System Works
²
TheAirbag Control Module (ACM)determines if a
frontal collision is severe enough to require the airbags
to inflate.
²The ACM will not detect side, roll over, or rear
impacts.
²The ACM also monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the START or ON position. These include all of the
items listed above except the knee bolster, the instru-
ment panel, and the steering wheel and column. If the
ignition key is in the OFF or ACC position, or not in
the ignition, the airbags are not on and will not inflate.
24 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

²Also, the ACM turns on the ªAirbag Warning Lightº in
the instrument panel for 6 to 8 seconds when the
ignition is first turned on, then turns the light off. If it
detects a malfunction in any part of the system, it turns
on the light either momentarily or continuously. If the
ACM detects a malfunction, the ªAirbag Warning
Lightº will illuminate for a minimum of 12 seconds
and will remain illuminated as long as the malfunction
exists.
WARNING!
Ignoring the ªAirbag Warning Lightº in your instru-
ment panel could mean you won't have the airbags
to protect you in a collision. If the light does not
come on, stays on after you start the vehicle, or if it
comes on as you drive, have the airbag system
checked right away.
²TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and in the
instrument panel. When the ACM detects a collision
requiring the airbags, it signals the inflator units. A
large quantity of nontoxic gas is generated to inflate
the airbags. The airbag covers separate and fold out of
the way as the bags inflate to full size. The bags fully
inflate in about 50 milliseconds. This is about half of
the time it takes to blink your eyes. The airbags then
quickly deflate while helping to restrain the driver and
front passenger. The driver's front airbag gas is vented
through the airbag material towards the instrument
panel. The passenger's front airbag gas is vented
through vent holes in the sides of the airbag. In this
way the airbags do not interfere with your control of
the vehicle.
²TheKnee Impact Bolstershelp protect the knees and
position the driver and front passenger's for the best
interaction with the front airbag.

Passenger Airbag On/Off Switch Ð If Equipped
NOTE:
The Passenger Airbag ON/OFF Switch is de-
signed so that the switch position can be changed using
the ignition key. The key inserts into the switch far
enough to fully depress a spring-loaded locking plunger,
and then rotates to the desired position. The key will not
insert fully into the switch, and the spring-loaded locking
plunger prevents the key from remaining in the switch.
The Passenger Airbag ON/OFF Switch is located on the
instrument panel. The switch is to be turned off only if
the passenger is an infant (less than 1 year old) or a child
(age 1 to 12) who must ride in the front seat because there
is no rear seat.
WARNING!
Whenever an airbag is turned off, even a lap/
shoulder belted passenger may hit their head, neck,
or chest on the dashboard (instrument panel) or
windshield in a crash. This may result in serious
injury or death.
26 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 because the airbags are 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, vehicle body struc-
ture, or frame.
²You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolster.
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 airbags.
Airbag Warning Light
You will want to have the airbags ready to inflate for your
protection in an collision. While the airbag system is
designed to be maintenance free, if any of the following
occurs, have an authorized dealer service the system
immediately.
²The ªAirbag Warning Lightº does not come on or
flickers during the 6 to 8 seconds when the ignition
switch is first turned on.
²The ªAirbag Warning Lightº remains on or flickers
after the 6 to 8 second interval.
²The ªAirbag Warning Lightº flickers or comes on and
remains on while driving.
Child Restraint
Everyone in your vehicle needs to be buckled up all the
time-babies and children, too. Every state in the United
States and all Canadian provinces require that small
children ride in proper restraint systems. This is the law,
and you can be prosecuted for ignoring it.

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 indicator check when the ignition switch is
first turned on. If the indicator is not lit during starting,
have it serviced. 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 feel the air
directed against the windshield.
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.
