Enhanced Traction System Warning Light
(3100 V6 or 3800 V6 Engine)
The Enhanced Traction System warning light may come
on for the following reasons:
D If you turn the system off by pressing the TRAC
button on the far right hand side of the driver
information center or trip computer (if equipped), 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 “Enhanced Traction System”
in the Index for more information.
D If the Enhanced Traction System warning light
comes on and stays on for an extended period of
time when the system is turned on, your vehicle
needs service. Adjust your driving accordingly.
D If the traction control system is affected by an
engine
-
related problem, the system will turn off and
the warning light will come on.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
Low Traction Light
If you have the Enhanced
Traction System or the
Traction Control System,
this light will also come on
when the system is limiting
wheel spin.
You may feel or hear the system working, but this is
normal. Slippery road conditions may exist if the low
traction light comes on, so adjust your driving
accordingly. The light will stay on for a few seconds
after the anti
-
lock system stops adjusting brake pressure
or the Enhanced Traction System or the Traction
Control System stops limiting wheel spin. See
“Enhanced Traction System” or “Traction Control
System” in the Index.
The low traction light also comes 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 there to tell you when
the Traction Control System or Enhanced Traction
System is active.
