    • For vehicles equipped with the 2.2L L4 engine, turn the system off by pressing the traction control button located on the instrument panel above the audio system. The warning light will come on and stay on. 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 the 3.5L V6 engine, the traction control system will be turned off when the shift lever is in REVERSE (R) or LOW (L). The traction control system warning light will be displayed on the instrument panel. The traction control system can be activated again by selecting DRIVE (D) or INTERMEDIATE (I).
    • 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.
