yellowblue Adding Washer Fluid 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 There are two windshield washer fluid tanks. The upper tank (shown above) will empty first. When the lower tank contains 0.5 quarts (0.5 liters) or less, the message LOW WASHER FLUID will be displayed on the Driver Information Center. Open the cap labeled WASHER FLUID ONLY. Add washer fluid until the tank is full. D 6-27
