If your vehicle has "ABS" brakes, an amber light (and the red BRAKE warning light) should come on when you start your engine. The Amber ABS light should stay on for a few seconds and then go out. That's normal. If it doesn't, it probably means that the bulb is burned out. Be sure to have a burned out bulb replaced.
If there is a problem with the "ABS" warning light circuitry and the "ABS" module is unable to turn on the amber "ABS" warning light, the "ABS" module will request the powertrain control module (PCM) to turn on the "SERVICE" light to alert the driver.
The "ABS" brake system has built in self-check features that performed each time you start your engine, back-up, and the first time you drive above 8 mph (15 km/h) after engine startup. It does not occur each time you back up or drive away.
If the amber 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 stay on, or comes on again while 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.
If the amber light flashes when you're driving, you don't have anti-lock brakes, and there could be a problem with your regular brakes. See Brake System Warning Light in this section for more information. Pull off the road and stop carefully. you may notice that the pedal is harder to push or, the pedal may go closed to the floor. It may take longer to stop. Have your Saturn towed for service, see Towing Your Vehicle .
