Driving and Operating Examples of these conditions include hard acceleration in a turn, an abrupt upshift or downshift of the transmission or driving on rough roads. If cruise control is being used when TCS begins to limit wheel spin, the cruise control automatically disengages. The cruise control can be re-engaged when road conditions allow. See Cruise Control on page 9‑57 for more information. TRACTION FAILED appears on the Driver information Center (DIC) when a TCS or antilock brake system problem has been detected and the vehicle needs service. When this message is on, the system will not limit wheel spin. Adjust your driving accordingly. See Driver Information Center (DIC) on page 5‑18 for more information. It is recommended to leave the system on for normal driving conditions, but it may be necessary to turn the system off if the vehicle is stuck in sand, mud, ice, or snow, and it is necessary to "rock" the vehicle to attempt to free it. See If the Vehicle is Stuck on page 9‑26 for more information. 9-53 TCS automatically comes on whenever the vehicle is started and resets itself at each ignition cycle. Adding non‐dealer/non‐retailer accessories can affect the vehicle's performance. See Accessories and Modifications on page 10‑3. StabiliTrak System To turn the system off, press and release the TCS/StabiliTrak button. The vehicle has a vehicle stability enhancement system called StabiliTrak. It is an advanced computer controlled system that assists the driver with directional control of the vehicle in difficult driving conditions. StabiliTrak activates when the computer senses a difference between the intended path and the direction the vehicle is actually traveling. StabiliTrak selectively applies braking pressure at any one of the vehicle's brakes to assist the driver with keeping the vehicle on the intended path. When TCS has been turned off, this light comes on steady and TRAC OFF appears on the DIC. This light flashes when TCS is active. Press and release the TCS/StabiliTrak button again to turn the system back on. The TRAC OFF message then goes off.
