Anti-Lock Brake System Light
(If equipped)
This warning light will go on each time you
start your vehicle. If it remains on for longer
than 5 seconds, you should shut off your engine
and restart. If the anti-lock brake light stays on,
this indicates that the anti-lock feature is
disabled and should receive immediate attention
by a qualified service technician. Normal braking
is not affected unless the brake warning light is
also lit.
The Anti-Lock Brake System has self-check
capabilities. As previously described, the system
turns on the anti-lock light each time you start
your engine. After the engine is started and the
anti-lock light is out, the system performs
another test the first time the vehicle reaches
14 mph (22 km/h). The system turns on the
Anti-Lock Brake System (ABS) pump motor for
approximately 1/2 second. At this time a
mechanical noise may be heard. This is a normal
part of the self-check feature. If a malfunction is
found during this check the anti-lock light will
come on.
