Low Tire Pressure Warning Light This light should come on briefly as you start the engine. Traction Control System (TCS) Warning Light If the vehicle has the Traction Control System (TCS), this light may come on for the following reasons: • The traction control button, located on the center console, is pressed, turning the system off. The light will stay on. To turn the system back on, press the button again and the warning light should go out. See Traction Control System (TCS) on page 292 for more information. • If there is a brake system problem that is specifically related to traction control, the TCS will turn off and the warning light will come on. • If the brakes begin to overheat, the TCS will turn off and the warning light will come on until the brakes cool down. If the TCS warning light comes on and stays on for an extended period of time when the system is turned on, the vehicle needs service. This light will also come on when one or more of your tires is significantly under-inflated. Stop and check your tires as soon as it is safe to do so. If underinflated, inflate them to the proper pressure. See Tires on page 400 for more information. This light will flash for 60 seconds and then turn on solid if a problem is detected with the Tire Pressure Monitor System. See Tire Pressure Monitor System on page 409 for more information. 178
