Your vehicle may have a Traction Control System (TCS) warning light. The TCS warning light may come on for the following reasons:

    • If you turn the TCS off by pressing the TRAC OFF button located in the instrument panel switchbank the TCS warning light will come on and stay on. To turn the system back on, press the button again. The TCS warning light should go off. See Traction Control System (TCS) for more information.
    • If there is an engine-related and brake system problem that is specifically related to traction control, the TCS will turn off and the TCS warning light will come on.

If the TCS warning light comes on and stays on for an extended period of time when the system is turned on, your vehicle needs service.
