Warning Light
Your vehicle may have
the Anti-Lock Brake
System (ABS).
This light will come on when your engine is
started and may stay on for several seconds.
That is normal.
If the ABS warning light comes on and stays on,
there may be a problem with the anti-lock
portion of the brake system. If the brake system
warning light is not on, you still have brakes,
but you do not have anti-lock brakes. SeeBrake
System Warning Light on page 186.
If the light stays on, turn the ignition to OFF. 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 whileyou 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 anti-lock
brakes. If the regular brake system warning light
is also on, you do not have anti-lock brakes
and there is a problem with your regular brakes.
SeeBrake System Warning Light on page 186.
The ABS warning light should come on brie y
when you turn the ignition key to RUN. If the light
does not come on then, have it xed so it will
be ready to warn you if there is a problem.
