If your vehicle is in cruise control when the TAS begins
to limit wheel spin, the cruise control will automatically
disengage. When road conditions allow you to safely
-
use it again, you may re engage the cruise control.
See "Cruise Control" in the Index. When the TRAC
OFF light on the button is on, the TAS is off and will
not limit wheel spin. Adjust your driving accordingly.
The TRAC OFF light on the button will come on under
the following conditions:
D
The Traction Assist System is turned off, either by
pressing the TAS on/off button or turning off the
automatic engagement feature of the TAS.

The Traction Assist System, as delivered from the
factory, will automatically come on whenever you start
your vehicle. To limit wheel spin, especially in slippery
road conditions, you should always leave the system on.
But you can turn the TAS off if you ever need to.
You should turn the TAS off if your vehicle ever gets
stuck in sand, mud or snow and rocking the vehicle is
required. See "Rocking Your Vehicle" in the Index.
You can turn the system back on at any time by pressing
the button again. The TRAC OFF light on the button
should go off.
To turn the system on or
off press the TAS on/off
button located near the
shift lever. If you used the
button to turn the system
off, the TRAC OFF light
on the button will come on
and stay on.
