The Traction Control System (TCS) warning light may come on for the following reasons:

    • The system is turned off by pressing the traction control button located above the audio system on the instrument panel. The warning light will come on and stay on. Press the button again, to turn the system back on. The warning light should go off. See Traction Control System (TCS) for more information.
    • An engine and brake system problem related to traction control makes the TCS turn off.

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.
