Antilock Brake System Warning Light For vehicles with the Antilock Brake System (ABS), this light comes on briefly when the engine is started. For vehicles with a Driver Information Center (DIC), see DIC Warnings and Messages on page 3-54 for all brake related DIC messages. Traction Control System (TCS)/ StabiliTrak® Warning Light The Traction Control System/StabiliTrak® warning light should come on briefly when the engine is started. 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 3-37. If the warning 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 when you are driving, there may be a problem with your Traction Control System (TCS)/StabiliTrak® and your vehicle may need service. When this warning light is on, the system will not limit wheel spin. Adjust your driving accordingly. If the traction control system warning light comes on and stays on for an extended period of time when the system is turned on, your vehicle needs service. See Traction Control System (TCS) on page 4-6 and StabiliTrak® System on page 4-8 for more information. 3-38
