If your vehicle has a Driver information Center (DIC), a TRACTION FAILED message will appear when a Traction Control System or Anti-Lock Brake System problem has been detected and the vehicle needs service. See DIC Warnings and Messages on page 196 for more information. When this message is on, the system will not limit wheel spin. Adjust your driving accordingly. 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. To turn the system off, press and hold the TCS button for five seconds. This light will come on steady when the traction control system has been turned off. This light flashes when TCS is active. If you press and hold the TC button for five seconds, the traction control system will turn off and a TRAC OFF message will appear on the DIC. Press the TC button again to turn the system back on. The TRAC OFF message will then go off. The traction control system will reset itself at each ignition cycle. Adding non-GM accessories can affect your vehicle's performance. See Accessories and Modifications on page 314 for more information. 242
