Anti-Lock Brake System Warning Light - Oldsmobile 1999 Cutlass Owner's Manual

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've
pulled off the road and stopped carefully, have
the vehicle towed for service.
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 it stays on after your parking brake is fully
released, it means you have a brake problem.

Anti-Lock Brake System Warning Light

If the light stays on, turn the ignition to OFF. Or, if the
light comes on and the chime sounds 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 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
brakes and there's a problem with your regular brakes.
See "Brake System Warning Light" 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.

With the anti lock brake
system, this light will come
on when you turn your
ignition on or start your
engine and it will stay on
for three seconds.
That's normal.
