Anti-Lock Brake System Warning Light With the anti-lock brake system, this light will come on briefly when you start your engine to show it is working. Then it will turn off. This is normal. Traction Off Light If you have the traction control system, this light will come on when the traction control system has been turned off. This light will come on briefly when the ignition is turned to ON, if it does not the system may require service. If the light stays on, or comes on when you're driving, your vehicle needs service. If the regular brake system warning light isn't on, you still have brakes, but you don't have anti-lock brakes. If the regular brake system warning light is also on, you don't have anti-lock brakes and there's a problem with your regular brakes. See Brake System Warning Light on page 3-32. The anti-lock brake system warning light should come on briefly when you turn the ignition key to ON. If the light doesn't come on then, have it fixed so it will be ready to warn you if there is a problem. For more information on the traction off light, see Traction Control System (TCS) on page 4-9. StabiliTrak® Not Ready Light If you have the StabiliTrak® system, this light will come on when the StabiliTrak® system has been turned off. This light will come on briefly when the ignition is turned to ON, if it does not the system may require service. For more information, see StabiliTrak® System (Automatic Transmission) on page 4-11. 3-33
