Anti-Lock Brake System Warning Light
If the light comes on when you're driving, you don't
-
have anti lock brakes and there could be a problem with
your regular brakes. Pull off the 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. Have the vehicle towed for service. (See "Towing
Your Vehicle" in the Index.)
-
With the anti lock brake
system, this light will come
on when you start your
engine and it will stay
on for three seconds.
That's normal.
CAUTION:
Your regular brake system may not be working
-
properly if the anti lock brake system warning
light is on. Driving with the anti
system warning light on can lead to an accident.
After you've pulled off the road and stopped
carefully, have the vehicle towed for service.
-
If the anti lock brake system warning light stays on
longer than normal after you've started your engine, turn
the ignition off. Or, if the light comes on and stays on
when you're driving, 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 you're driving, your vehicle needs service. If the
light is on and the regular brake system warning light
isn't on, you still have brakes, but you don't have
-
anti lock brakes.
-
The anti lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
