Adding Washer Fluid The windshield washer fluid reservoir is located in the engine compartment on the passenger's side of the vehicle, near the fuse and relay center. Open the cap with the washer symbol on it. 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 D 6-30
