9-36 Driving and Operating
The TCS/StabiliTrak warning light
flashes to indicate that the traction
control system is active.
This warning light comes on if there
is a problem with the traction control
system.
See Traction Off Light on
page 5 19. When this warning light
is on, the system does not limit
wheel spin. Adjust your driving
accordingly.
TCS automatically comes on
whenever the vehicle is started.
To limit wheel spin, especially in
slippery road conditions, the system
should always be left on. But, TCS
can be turned off if needed.
Notice: Do not repeatedly brake
or accelerate heavily when TCS is
off. The vehicle's driveline could
be damaged.
The TCS off light comes on to
indicate that the traction control
system has been turned off.
When TCS is switched off on AWD
vehicles, the system may still make
noise. This is normal and necessary
with the AWD hardware on the
vehicle.
It might be necessary to turn the
system off if the vehicle gets stuck
in sand, mud or snow and rocking
the vehicle is required. See If the
Vehicle is Stuck on page 9 11 for
more information. See also Winter
Driving on page 9 9 for
information on using TCS when
driving in snowy or icy conditions.
To turn the system off, press
located on the console to the right of
the shifter.
Press and release and the traction
control system turns off and the
traction control system warning light
comes on. Press 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 10 3 for more information.
