Antilock Brake System (ABS) Warning Light

This light comes on briefly when the engine is started.
If the light does not come on, have it fixed so it will be ready to warn if there is a problem.
If the ABS light stays on, turn the ignition off.
If the light comes on while driving, stop as soon as it is safely possible and turn off the vehicle. Then start the engine again to reset the system. If the ABS light stays on, or comes on again while driving, the vehicle needs service. A chime may also sound when the light comes on steady.
If the ABS light is the only light on, the vehicle has regular brakes, but the antilock brakes are not functioning.
If both the ABS and the brake system warning light are on, the vehicle's antilock brakes are not functioning and there is a problem with the regular brakes. See your dealer for service.
