Buick 1998 Century Owner's Manual page 133

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 vehicle 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.
Anti-Lock Brake System Active Light
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
active light will come on.

Slippery road conditions may exist if this light comes
on, so adjust your driving accordingly. The light will
stay on for a few seconds after the system stops
adjusting brake pressure.
The anti-lock brake system active light also comes 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
there to tell you when the system is active.
