If the vehicle has a Traction Control System (TCS), the traction control system warning light may come on for the following reasons:

    • When the system is turned off by pressing the traction control button located on the panel directly behind the automatic transaxle shift lever. 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 is a brake system problem that is specifically related to traction control. If the brakes begin to overheat, the traction control system will turn off and the warning light will come on until the brakes cool down.
    • If the traction control system is affected by an engine-related problem.
    • If there is a base brake problem with Full-Range Traction Control.

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