Traction Control System (TCS)
Warning Light
If the warning light does not come on then, have it fixed
so it will be ready to warn you if there is a problem. If
it stays on, or comes on when you are driving, there may
be a problem with your traction control system and
your vehicle may need service. When this warning light
is on, the system will not limit wheel spin. Adjust
your driving accordingly.
For vehicles equipped with
the traction control system,
this warning light should
come on briefly when
the engine is started.
The traction control system warning light may come on
for the following reasons:
•
If you turn the system off by pressing the
TRACTION CONTROL button located on the center
console, 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 (TCS) on page 4-9 for more
information.
•
If there is 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 is affected by an
engine-related problem, the system will turn off and
the warning light will come on.
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.
