Your vehicle is equipped with a traction control system warning light.

The traction control system warning light may come on for the following reasons:

    • If you turn the system off by pressing the traction control button. To turn the system back on, press the button again. The warning light should go off. See Traction Control System (TCS) for more information.
    • If there's a 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 your brakes begin to overheat, the traction control system will turn off and the warning light will come on until your brakes cool down.
    • If the traction control system is affected by an engine-related problem, the 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.
