Adding Washer Fluid The washer fluid warning light will come on when the ignition switch is on and the fluid container is less than one-third full. On vehicles with the optional Driver Information Center (DIC), a WASHER FLUID LOW message will be displayed and a chime will sound letting you know to add windshield washer fluid to your vehicle. Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview on page 5-14 for reservoir location. Notice: • When using concentrated washer fluid, follow the manufacturer's instructions for adding water. • Do not mix water with ready-to-use washer fluid. Water can cause the solution to freeze and damage your washer fluid tank and other parts of the washer system. Also, water does not clean as well as washer fluid. • Fill your washer fluid tank only three-quarters full when it is very cold. This allows for expansion if freezing occurs, which could damage the tank if it is completely full. • Do not use engine coolant (antifreeze) in your windshield washer. It can damage your washer system and paint. 5-41
