If your vehicle has the Traction Control System (TCS), this light may come on for the following reasons:

    • If you turn the system off by pressing the TC (traction control) button located on the center console, the light will come on and stay on. To turn the system back on, press the button again and the warning light should go out.
    • If there is a brake system problem that is specifically related to traction control, the TCS will turn off and the warning light will come on.

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