Traction Control System (TCS) Warning Light If the vehicle has the Traction Control System (TCS), this light may come on for the following reasons: That is normal. If the light does not come on then, have it fixed so it will be ready to warn you if there is a problem. If the ABS light stays on, turn the ignition off, if the light comes on when you are driving, stop as soon as it is safely possible and turn the ignition off. Then start the engine again to reset the system. If the ABS light still stays on, or comes on again while you are driving, your vehicle needs service. If the regular brake system warning light is not on, your vehicle still has brakes, but not antilock brakes. If the regular brake system warning light is also on, your vehicle does not have antilock brakes and there is a problem with the regular brakes. See Brake System Warning Light on page 3-45. For vehicles with a Driver Information Center (DIC), see DIC Warnings and Messages on page 3-67 for all brake related DIC messages. • The traction control button, located on the center console, is pressed, turning the system off.

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. 3-47
