This light should come on briefly when you start the engine. If it stays on or comes on while you are driving, there's a problem with your traction control system. See "Traction Control System Warning Light" in the Index. When this warning light is on, the system will not limit wheel spin. Adjust your driving accordingly. The traction control system automatically comes on whenever you start your vehicle. To limit wheel spin, especially in slippery road conditions, you should always leave the system on. But you can turn the traction control system off if you ever need to. You should turn the system off if your vehicle ever gets stuck in sand, mud or snow and rocking the vehicle is required. See "Rocking Your Vehicle" in the Index. To turn the system off, press the TRACTION OFF button located at the end of the shift lever on the right side of the steering wheel. The traction control system warning light will come on and stay on. If the system is limiting wheel spin when you press the button, the warning light will come on -- but the system won't turn off right away. It will wait until there's no longer a current need to limit wheel spin. You can turn the system back on at any time by pressing the button again. The traction control system warning light should go off. 4-10
