Antilock Brake System Warning Light For vehicles with the Antilock Brake System (ABS), this light will come on briefly when you start the engine. Traction Off Light If you have the Traction Control System (TCS), this light will come on when the TCS has been turned off. 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, you still have brakes, but you do not have antilock brakes. If the regular brake system warning light is also on, you do not have antilock brakes and there is a problem with your regular brakes. See Brake System Warning Light on page 3-33 For vehicles with a Driver Information Center (DIC), see DIC Warnings and Messages on page 3-43 for all brake related DIC messages. 3-34 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 on the traction off light, see Traction Control System (TCS) on page 4-5. 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 on page 4-7.
