The TCS warning light comes on briefly when the engine is started.

If it does not, have the vehicle serviced by your dealer/retailer.

If the Traction Control System (TCS) warning light comes on and stays on, there may be a problem with the TCS.

The light also comes on if the TCS is turned off using the traction control on/off button located on the console.

If this light stays on or comes on while driving, pull off the road as soon as possible and stop carefully. Turn the engine off and then restart it. If the light still stays on or comes back on again while driving, the vehicle needs service. Have the TCS inspected as soon as possible. See Traction Control System (TCS) and StabiliTrak® System for more information.

Also see Competitive Driving Mode for more information.
