Chevrolet Sonic Owner's Manual: Antilock Brake System (ABS) Warning Light
This light comes on briefly when the engine is started.
If the light stays on, turn the ignition to LOCK/OFF or if the light comes on, 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 driving, the vehicle needs service. See your dealer.
