Cadillac 2008 CTS - Manual (Page 252)

Traction Control System (TCS)
Your vehicle has a Traction Control System (TCS) that
limits wheel spin. This is especially useful in slippery road
conditions. It will activate and the TCS/StabiliTrak
® light
will flash if it senses that any of the wheels are spinning or
beginning to lose traction while driving. When this
happens, the system applies the brake to the spinning
wheel(s) and/or reduces engine power to limit wheel spin.
The TCS/StabiliTrak
® warning light will flash when the
traction control system is limiting wheel spin.
You may feel or hear the system working, but this is
normal.
This warning light will flash
if there is a problem with
the traction control system.
See Traction Control System (TCS)/StabiliTrak ®
Warning Light on page 3-38 and StabiliTrak ® System on
page 4-8. When the TCS/StabiliTrak ® warning light is
on, the system will not limit wheel spin. Adjust your
driving accordingly.
TCS automatically comes on whenever vehicle is
started. To limit wheel spin, especially in slippery road
conditions, you should always leave the system on.
But the TCS should be turned off if your vehicle
ever gets stuck in sand, mud or snow and rocking the
vehicle is required. Also, turn the TCS off while in
deep snow or on loose gravel, to assist vehicle motion
at lower speeds. See Rocking Your Vehicle to Get
It Out on page 4-22 for more information. See also
Winter Driving on page 4-18 for information on using
TCS when driving in snowy or icy conditions.
