2010 Cadillac STS Owner's Manual - Page 328

The system may be heard or felt while it is working, but this is normal. This warning light comes on if there is a problem with TCS. 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. To turn the system off, press the TCS/StabiliTrak button located near the shift lever. See Traction Control System (TCS) Warning Light on page 4‑60. When this warning light is on, the system will 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. 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 5-10 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® on 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.
