Warning Lights, Gages
and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle's functions. As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they're working. If you are
familiar with this section, you should not be alarmed
when this happens.

2-77
Gages can indicate when there may be or is a problem
with one of your vehicle's functions. Often gages and
warning lights work together to let you know when
there's a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual's advice.
Waiting to do repairs can be costly
-- and even
dangerous. So please get to know your warning lights
and gages. They're a big help.
Your vehicle may also have a Driver Information Center
(DIC) that works along with the warning lights and
gages. See ªDriver Information Centerº in the Index.
The volume of your vehicle's warning chimes can be
adjusted. For more information see ªChime Level
Adjustmentº in the Index.
Safety Belt Reminder Light
When the key is turned to ON or START, a chime will
come on for about eight seconds to remind people to
fasten their safety belts.
The safety belt light will
also come on and stay on
for about 20 seconds, then
flash for about 55 seconds.
If the driver's belt is already buckled, the light will
come on briefly, but the chime will not sound.

2-78
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 sensors, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the air bag system, see ªAir
Bagº in the Index.
This light will come on
when you start your vehicle,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to ON. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
On vehicles with the DIC, a SERVICE AIR BAG
message will be displayed when there is a problem with
the air bag system. See ªDIC Warnings and Messagesº
in the Index for more information.

2-79 Battery Warning Light (If Equipped)
This light will come on
briefly when you start the
vehicle, as a check to show
you it is working; then it
should go out.
If it stays on, or comes on while you are driving, you
may have a problem with the electrical charging system.
Have it checked right away. Driving while this light is
on could drain your battery and result in a vehicle that
may stall.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and comfort control system.
Some instrument panel clusters with a voltmeter gage do
not have a battery warning light. They have a CHECK
GAGES warning to indicate a problem.

unless you have the
supercharged engine.
When the ignition is running, the gage shows the
condition of the charging system. Readings between the
shaded warning zones indicate the normal operating
range. Readings in the shaded warning zones indicate a
possible problem in the electrical system.
On vehicles with the systems monitor, the CHECK
GAGES light will also come on, and a warning chime
will sound if there is a problem in the electrical system.
Have your vehicle serviced immediately.

road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop. If the light is still on, have the
vehicle towed for service. See ªTowing Your Vehicleº in
the Index.
CAUTION:
Your brake system may not be working properly

When the ignition is on, the brake system warning light
will also come on when you set your parking brake. The
light will stay on if your parking brake doesn't release
fully. If you try to drive off with the parking brake set, a
chime will also come on until you release the parking
brake. If the light stays on after your parking brake is
fully released, it means you have a brake problem.

possible and turn the ignition off. Then start the engine
again to reset the system. If the light still stays on, or
comes on again while you're driving, your vehicle needs
service. If the regular brake system warning light isn't
on, you still have brakes, but you don't have anti
-lock
brakes. If the regular brake system warning light is also
on, you don't have anti
-lock brakes and there's a
problem with your regular brakes. See ªBrake System
Warning Lightº earlier in this section.
The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to ON. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
