Traction Control System (TCS) Warning Light Your vehicle may have the traction control system. If it does, this warning light may come on for the following reasons: • 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 warning light comes on and stays on for an extended period of time when the system is turned on, your vehicle needs service. • If you turn the system off by pressing the TRAC OFF button located on the instrument panel, a chime will sound and 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. 3-35
