If the light still stays on, or comes on again while you're driving, your vehicle needs service. If the light is on and the regular brake system warning light isn't on, you still have brakes, but you don't have anti-lock brakes. The anti-lock brake system warning light should come on briefly when you turn the ignition key to RUN. This is normal. If the light doesn't come on then, have it fixed so it will be ready to warn you if there is a problem. @ If you turn the system off by pressing the TCS button located on the far right side of the trip computer, 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. 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 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. 3-29
