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 the ignition off. A chime may also sound when the light comes on steady. 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 5-23. See Brake System Messages on page 5-39 for all brake related DIC messages. 5-25 Lane Departure Warning (LDW) Light Up-Shift Light For manual transmission vehicles, there is an up-shift light that comes on in the lower DIC area. It shows when to shift to the next higher gear for best fuel economy. See Manual Transmission on page 9-29. For some vehicles with the Lane Departure Warning (LDW) system, this light comes on briefly while starting the vehicle. If it does not come on, have the vehicle serviced. For vehicles with the uplevel cluster, this light may not come on when starting the vehicle. This light is green if LDW is on and ready to operate. This light changes to amber and flashes to indicate that the lane marking has been crossed without using a turn signal in that direction. See Lane Departure Warning (LDW) on page 9-58.
