For 1990-2009 cars

With the anti-lock brake system, this light will come on when you start your engine and may stay on for several seconds. That's normal.

If the light stays on, turn the ignition "OFF". Or, if the light comes on when you're driving, stop as soon as possible and turn 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 Saturn needs service. If the regular brake system warning light isn't on, you still have brakes, but you don't have anti-lock brakes. Adjust your driving accordingly. If the regular brake system warning light is also on, you don't have anti-lock 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 "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.
