Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag’s electrical system for malfunctions.
The system check includes the air bag modules, the
wiring and the crash sensing and diagnostic module. For
more information on the air bag system, seeAir Bag
Systems on page 1-46.
This light will come on
when the vehicle is
started, and it will ash for
a few seconds. Then
the light should go out.
This means the system is
functioning properly.
If the air bag readiness light stays on after the vehicle is
started, or comes on as the vehicle is being driven,
there may be an electrical problem and the air
bag system may not work properly. Have the 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 inate in a crash, or they
could even inate 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 ash for a few
seconds when you turn the ignition key to RUN. If the
light does not come on then, have it xed so it will
be ready to warn you if there is a problem.
3-30

When the ignition is on, the brake system warning light
will also come on when the parking brake is set.
The light will stay on if the parking brake does not
release fully. If it stays on after the parking brake is fully
released, it means there is a brake problem.
If the light comes on while the vehicle is being driven,
pull off the road and stop carefully. The pedal may
be harder to push. or it may go closer to the oor. It may
take longer to stop. If the light is still on, have the
vehicle towed for service. SeeTowing Your Vehicle on
page 4-31.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you have pulled off the road and
stopped carefully, have the vehicle towed for
service.
Anti-Lock Brake System
Warning Light
If the vehicle has anti-lock brakes, this warning light will
come on for a few seconds when the ignition key is
turned to RUN. If the anti-lock brake system warning light
stays on longer than normal after the engine has been
started, turn the ignition off. Or, if the light comes on and
stays on while the vehicle is being driven, stop as soon as
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 driving, the anti-lock brake system
needs service. If the light is on and the regular brake
system warning light is not on, the vehicle still has brakes,
but it does not have anti-lock brakes.
The anti-lock brake system warning light will come on
briey when the ignition key is turned to RUN. This
is normal. If the light does not come on then, have it
xed so it will be ready to warn you if there is a problem.United States
