Antilock Brake System (ABS)
Warning Light
This light comes on briefly when the vehicle is
tu
rned on to show that the light is working. If
it does not come on then, have it fixed so it will
be ready to warn you if there is aproblem.
If the ABS warning light stays on, or comes
on again while driving, the vehicle needs
service. Achime may also sound when the
light stays on.
If the ABS warning light is the only light on,
the vehicle has regular brakes, but ABS is
not functioning.
If both the ABS warning light and the brake
system warning light are on, ABS is not
functioning and there is aproblem with the
regular brakes. See your dealer for service.
