Windshield Washer Fluid What to Use When you need windshield washer fluid, be sure to read the manufacturer's instructions before use. If you will be operating your vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing. 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. Adding Washer Fluid Your vehicle has a message that comes on when the washer fluid is low. The message is displayed for 15 seconds at the start of each ignition cycle if the fluid is low. When the CHECK WASHER FLUID message is displayed, you will need to add washer fluid to the windshield washer fluid reservoir. See DIC Warnings and Messages on page 3-48 for more information. Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview on page 5-12 for reservoir location. • 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. 5-34
