Anti-Lock Brake System Warning Light With the anti-lock brake system, the light will come on when your engine is started and may stay on for several seconds. That is normal. Traction Control System (TCS) Warning Light This light should come on briefly as you start the engine. 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 light stays on, turn the ignition to OFF. Or, if the light comes on when you are driving, stop as soon as possible and turn the ignition off. Then start the engine again to reset the system. If the 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, you still have brakes, but you do not have anti-lock brakes. If the regular brake system warning light is also on, you do not have anti-lock brakes and there is a problem with your regular brakes. See Brake System Warning Light on page 3-38. Also see "Service ABS" under DIC Warnings and Messages on page 3-58. The anti-lock brake system warning light will come on briefly when you turn the ignition key to ON. This 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 it stays on, or comes on and the DIC shows a SERVICE TRACTION SYSTEM message when you are driving, there is a problem with your TCS system and your vehicle needs service. When this light is on, the system will not limit wheel spin. Adjust your driving accordingly. If the driver turns off the Traction Control System by pressing the button on the console, the TCS system light will come on and the TRACTION SYSTEM OFF message will show on the DIC. 3-39
