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 five 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.
