Antilock Brake System
(ABS) Warning Light
.
United States
The ABS warning light comes on
briefly when the ignition key is
turned to ON/RUN. This is normal.
If the light does not come on then,
have it fixed so it will be ready to
warn you if there is a problem.
If the light stays on, turn the ignition
to LOCK/OFF. If the light comes
on while 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
driving, the vehicle needs service.
If the regular brake system warning
light is not on, there are still brakes,
but no antilock brakes. If the regular
brake system warning light is also
on, there are no antilock brakes and
there is a problem with the regular
brakes. See
