Chevrolet 2000 Prizm Owner's Manual page 120

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 (Option)
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.
