Cadillac STS 2011 Owner's Manual page 323

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.
Do not repeatedly brake or accelerate
heavily when TCS is off. The vehicle's driveline
could be damaged.
When TCS is turned off on a vehicle with AWD, the
system may still be working. This is normal and
necessary with the hardware on the vehicle.
It may be necessary to turn the system off if the vehicle
gets stuck in sand, mud or snow and rocking the vehicle
is required. See Rocking Your Vehicle to Get It Out on
page 5 23 and If Your Vehicle is Stuck in Sand, Mud,
Ice, or Snow on page 5 22 for more information. See
Winter Driving on page 5 20 for information on using
TCS when driving in snowy or icy conditions.

For AWD vehicles with the Active Steering with
Enhanced StabiliTrak option, the TCS/StabiliTrak button
is used to turn traction control on and off and to turn
StabiliTrak on and off. See Enhanced StabiliTrak
page 5 7 for instructions on selecting the proper
stability control mode.
Press and release the TCS/StabiliTrak button and TCS
will turn off and the Traction Control System Warning
Light will come on. Press the button again to turn the
system back on.
Adding non GM accessories can affect the vehicle's
performance. See Accessories and Modifications on
page 6 4 for more information.
To turn the system off,
press the TCS/StabiliTrak
button located near the
shift lever.
