Antilock Brake System (ABS) Warning Light For vehicles with the Antilock Brake System (ABS), this light comes on briefly when the engine is started. Enhanced Traction System (ETS) Indicator/Warning Light For vehicles with the Enhanced Traction System (ETS), this light serves as an indicator and warning light. If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator light then goes off. If the ABS light stays on, turn the ignition off. If the light comes on while 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 stays on, or comes on again while driving, the vehicle needs service. If the regular brake system warning light is not on, the vehicle still has brakes, but not antilock brakes. If the regular brake system warning light is also on, the vehicle does not have antilock brakes and there is a problem with the regular brakes. See Brake System Warning Light on page 3-29. For vehicles with a Driver Information Center (DIC), see DIC Warnings and Messages on page 3-46 for all brake related DIC messages. 3-30 This light comes on briefly while the engine is started. If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator light then goes off. If the indicator/warning light is on and not flashing, the ETS system could have been disabled. Check all related Driver Information Center (DIC) messages to determine whether the system has been turned off or if the system is not working properly and the vehicle requires service. If the ETS has been disabled, wheel spin is not limited. If the indicator/warning light is on and flashing, the ETS is actively working. The LOW TRACTION DIC message also appears when the system is actively limiting wheel spin. See Enhanced Traction System (ETS) on page 4-13 and DIC Warnings and Messages on page 3-46 for more information.
