2007 Cadillac STS Owner's Manual - Page 324

The traction control system automatically comes on whenever you start your vehicle. To limit wheel spin, especially in slippery road conditions, you should always leave the system on. But you can turn the traction control system off if you ever need to. Notice: Do not repeatedly brake or accelerate heavily when the TCS is off. You could damage your vehicle's driveline. When the TCS is switched off on AWD and STS-V vehicles, you may still feel the system working. This is normal and necessary with the hardware on your vehicle. You should turn the system off if your vehicle ever gets stuck in sand, mud or snow and rocking the vehicle is required. See Rocking Your Vehicle to Get It Out on page 349 and If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 348 for more information. See also Winter Driving on page 344 for information on using TCS when driving in snowy or icy conditions. To turn the system off, press the TC (traction control) button located near the shift lever. If you press the TC button once, the traction control system will turn off and the traction control system warning light will come on. Press the TC button again to turn the system back on. If you press and hold the TC button for five seconds, the StabiliTrak® system and the traction control system will turn off. Press the TC button again to turn StabiliTrak® back on. For more information, see StabiliTrak® System on page 326. Adding non-GM accessories can affect your vehicle's performance. See Accessories and Modifications on page 363 for more information. 324
