5-20 Instruments and Controls If the light does not come on, have it fixed so it will be ready to warn if there is a problem. 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 off the vehicle. 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. A chime may also sound when the light comes on steady. If the ABS light is the only light on, the vehicle has regular brakes, but the antilock brakes are not functioning. If both the ABS and the brake system warning light are on, the vehicle's antilock brakes are not functioning and there is a problem with the regular brakes. See your dealer for service. See Brake System Warning Light on page 5-19 and Brake System Messages on page 5-35. If this light stays on, there is a problem with the Electric Parking Brake system or another system on the vehicle that is causing the parking brake system to work at a reduced level. The vehicle can still be driven, but should be taken to a dealer as soon as possible. See the information for the Electric Parking Brake under Parking Brake on page 9-32. If a message displays in the Driver Information Center (DIC), see Brake System Messages on page 5-35. Lane Departure Warning (LDW) Light Antilock Brake System (ABS) Warning Light This light comes on briefly while starting the vehicle. If it does not, have the vehicle serviced by your dealer. If the system is working normally, the light then turns off. This light comes on green when the system is on and ready to operate. When the system determines that the vehicle is leaving its lane without using the turn signal, this light will change to amber and flash. See Lane Departure Warning (LDW) on page 9-57. This light comes on briefly when the engine is started.
