Adding Washer Fluid When your vehicle's windshield washer fluid level becomes low, a CHECK WASHER FLUID message will appear on the Driver Information Center (DIC). You will need to add fluid soon. Open the cap labeled WASHER FLUID. Add washer fluid until the tank is full. NOTICE: D When using concentrated washer fluid, D follow the manufacturer's instructions for adding water. Don't 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 doesn't clean as well as washer fluid. Fill your washer fluid tank only three-quarters full when it's very cold. This allows for expansion if freezing occurs, which could damage the tank if it is completely full. Don't use engine coolant (antifreeze) in your windshield washer. It can damage your washer system and paint. D The windshield washer fluid reservoir is located next to the fuse relay center on the passenger's side of the engine. See "Engine Compartment Overview" in the Index for more information on location. D 6-29
