With the Antilock Brake System (ABS), this light will come on briefly when the engine is started.

If the ABS warning light comes on and stays on, there may be a problem with the antilock portion of the brake system. If the red BRAKE light is not on, you still have brakes, but you do not have antilock brakes. See Brake System Warning Light .

If the light stays on, turn the ignition to OFF or ACCESSORY. If the light comes on when you are 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 are driving, your vehicle needs service. If the regular brake system warning light is not on, you still have brakes, but you do not have antilock brakes. If the regular brake system warning light is also on, you do not have antilock brakes and there is a problem with your regular brakes. See Brake System Warning Light .
