Traction Control System (TCS) Warning Light If your vehicle has a Traction Control System (TCS), the traction control system warning light may come on for the following reasons: 0 With Full-Range Traction Control, if there is a base brake problem, the system will turn off and the 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. Low Traction Light If your vehicle has the traction control system, this light will come on when the system is limiting wheel spin. If you turn the system off by pressing the traction control button located on the black panel directly behind your automatic transaxle shift lever, 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) on page 4-10 for more information. With Full-Range Traction Control equipped vehicles, 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. LOW TRAC You mayfeel or hear the traction control system working, but this is normal. Slippery road conditions may existif the lowtraction light comes on, so adjust your driving accordingly. The light will stay on for a few seconds after the traction control system stops limiting wheel spin. See Traction Control System (TCS) on page 4- 10 or Full-Range Traction Control System on page 4-9. The low traction light also comes on briefly when you turn the ignition key to RUN. If the light doesn't come on then, have it fixed so it will be there to tell you when the traction control system is active. 3-34
