Anti-Lock Brake System Warning
Light
United States
If your vehicle has anti-lock brakes, this warning light
will come on for a few seconds when you turn the
ignition key to RUN. If the 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 stays on, or comes on again while you're driving, the
anti-lock brake system needs service. If the light is on
and the regular brake system warning light isn't on, you
still have brakes, but you don't have anti-lock brakes.
The anti-lock brake system warning light will come
on briefly when you turn the ignition key to RUN. This is
normal. If the light doesn't come on then, have it
fixed so it will be ready to warn you if there is a problem.
