Anti-Lock Brake System Warning Light
With the anti
-
lock brake
system, this light will come
on when you start your
engine and it will stay on
for three seconds.
That’s normal.
If the anti
-
lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition off. Or, if the light comes on and stays on
when you’re 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
while you’re driving, your vehicle needs service. If the
light is on and the regular brake system warning light
isn’t on, you still have brakes, but you don’t have
anti
-
lock brakes. Adjust your driving accordingly.
The anti
-
lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed so it will be
ready to warn you if there is a problem.
Traction Control System Warning Light
(3800 Supercharged V6 Engine Only)
The traction control system warning light may come on
for the following reasons:
D If you turn the system off by pressing the TCS button
located on the far right hand side of the Driver
Information Center, the warning light will come on and
stay on. To turn the system back on, press the button
again. The warning light should go off. (See “Traction
Control System” in the Index for more information.)
D If there’s a brake system problem that is specifically
related to traction control, the traction control system
will turn off and the warning light will come on. If
your brakes begin to overheat, the traction control
system will turn off and the warning light will come
on until your brakes cool down.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
