Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG. The system checks the
air bag’s electrical system for malfunctions. The light
tells
you if there is an electrical problem. The system
check includes
the air bag sensor, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information
on the air bag system, see “Air
Bag” in the Index.
AIR
BAG
You will see this light flash
for a few seconds when you
turn your ignition
to RUN
or START. Then the light
should
go out. This means
If the air bag readiness light doesn’t come on when you
start your vehicle, or stays
on, or comes on when you
are driving, your air bag system may not work properly.
Have your vehicle serviced right away.
Charging System Light
Irl
~ This light should come on
1 briefly when you turn on the
ignition, before starting the
1 engine, as a check to show
you it is working.
After the engine starts, the light should go out. If it stays
on or comes
on while you are driving, you may have a
problem with your charging system. It could indicate a
problem with the alternator drive belt, or some other
charging system problem. Have
it checked right away.
Driving while this light is on could drain your battery.
If you must drive a short distance
with this light on, it
helps to turn off all your accessories, such as the radio
and air conditioner.

Malfunction Indicator Lamp (Service Engine Soon Light) (Gasoline Engine)
Your vehicle is equipped
with a computer which
monitors operation of the

fuel, ignition and emission
control systems.
This system is called
OBD I1 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life
of the vehicle, helping to produce a cleaner
environment. The SERVICE ENGINE SOON light
comes on to indicate that there is a problem and service
is required. Malfunctions
often will be indicated by the
system before any problem
is apparent, which may
prevent more serious damage
to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running.
If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in
one
of two ways:
0
0
Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.

If the Light Is Flashing Are you low on fuel‘?
The following may prevent more serious damage to
your vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
0 Avoid steep uphill grades.
If towing a trailer, reduce the amount of cargo being
hauled as soon as
it is possible.
If the light stops flashing and remains on steady, see “If
the Light Is On Steady“ following.
If the light continues to flash, when it is safe to do so.
stop the vehicle. Put your vehicle in PARK (P). Turn the
key
off, wait at least 10 seconds and restart the engine.
If the light remains on steady, see
“If the Light Is On
Steady” following.
If the light is still flashing follow the
previous steps, and drive the vehicle to your dealer or
qualified service center for service.
If’ the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did
you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be c0rrecte.d when the electrical system
dries out. A few driving trips should turn the light off. As
your engine starts to run
out of fuel, your engine may
not run as efficiently as designed since
s~nall amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly.
It
will take a few driving trips to turn the light off.
Have you recently changed brands of fuel‘?
If so, be sure to fuel your vehicle with quality fuel (see
“FLE~”
in the Index). Poor fuel quality will cause your
engine not to
run as efficiently as designed. You may
notice this as stalling after start-up, stalling when
you put
the vehicle into gear, misfiring, hesitation on acceleration
or stumbling on acceleration. (These conditions may go
away once the engine is warmed up.) This will be
detected by the system and cause the light to turn on.
If you experience this condition, change the fuel brand
you use. It will require at least one full tank of the
proper fuel to
turn the light off.
If none
of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to
fix any mechanical or electrical
problems that
may have developed.
