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. A CAUTION: 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 off an accident. After you've pulled the road and stopped carefully, have the vehicle towed for service. I (@) If the light flashes when you're ( ving, you don'thave 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.) 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 havebrakes, 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 onthen, have it fixed so it will be ready to warn you if there is a problem.
