Anti-Lock Brake System Warning Light
(Option)
(@)
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.
If the light flashes when you're
(
ving, 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.)
A
CAUTION:
I
Your regular brake system may not be working
properly if the anti-lock brake system warning
light is flashing. Driving with the anti-lock
brake system warning light flashing 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 Pontiac needs service. If the
light is on but not flashing 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.
