Your vehicle may have a traction control system warning light. The traction control system warning light may come on for the following reasons:

    • For vehicles equipped with the traction control system and front-wheel drive, this light will come on and stay on if you turn the system off by pressing the traction control button located on the instrument panel above the audio system. To turn the system back on, press the button again. The warning light should go off. See Traction Control System (TCS) for more information.
    • For vehicles equipped with all-wheel-drive, this light will come on and stay on when the all-wheel-drive system is unable to protect for overheating under extended heavy all-wheel-drive usage.
    • If there is an engine-related and brake system problem that is specifically related to traction control, the traction control system 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.
