Anti-Lock Brake System
Warning Light
If your vehicle has anti-lock brakes, the anti-lock brake
system (ABS) warning light will come on briefly, as
a check, when you start your vehicle. If it doesn’t, have
your vehicle serviced so that the light works properly
when it needs to.
The ABS light is located in
the instrument panel
cluster, to the left of the
engine coolant temperature
gage.
If the light stays on longer than a few seconds after
you start your engine, or comes on and stays on
while you are driving, try resetting the system.
To reset the system, do the following:
1. If you are driving, pull over when it is safe to do so.
2. Be sure the vehicle is in PARK (P).
3. Turn off the ignition.
4. Then restart the engine.
If the light remains on after resetting the system or
comes on again while driving, your vehicle needs
service. If the ABS light is on, but the regular brake
system warning light is not on, you do not have anti-lock
brakes, but you still have regular brakes. Have your
vehicle serviced right away. If both brake lights are on,
you do not have anti-lock brakes, and there’s a
problem with your regular brakes as well. Have your
vehicle towed for service. See Towing Your Vehicle on
page 4-31.
