8-42 Driving and Operating
The TCS off light comes on and
Traction Control Off is displayed
on the Driver Information Center
(DIC) to indicate that the traction
control system has been turned off.
See Ride Control System Messages
on page 4 33.
On AWD vehicles, when TCS is
turned off, the system may still
make noise. This is normal and
necessary with AWD hardware.
It may be necessary to turn the
system off if the vehicle ever gets
stuck in sand, mud or snow and
rocking the vehicle is required. See
If the Vehicle is Stuck on page 8 22
for more information. See also
Winter Driving on page 8 20 for
information on using TCS when
driving in snowy or icy conditions.
Traction control can be turned off by
pressing and releasing the TCS/
StabiliTrak button, on the console,
until the TCS/StabiliTrak light comes
on the instrument panel and
Traction Control Off appears in the
DIC. Press the button again to turn
the system back on. For information
on turning StabiliTrak off and on,
see StabiliTrak System following in
this section.
Adding non GM accessories can
affect the vehicle's performance.
See Accessories and Modifications
on page 9 3 for more information.

StabiliTrak System

The vehicle has a vehicle stability
enhancement system called
StabiliTrak. It is an advanced
computer controlled system that
assists with directional control of the
vehicle in difficult driving conditions.
StabiliTrak activates when the
computer senses a difference
between the intended path and the
direction the vehicle is actually
traveling. StabiliTrak selectively
applies braking pressure at any one
of the vehicle's brakes to help steer
the vehicle in the intended direction.
