Adding Washer Fluid When the windshield washer fluid is low, a low washer fluid light may appear on the instrument panel cluster. See Low Washer Fluid Warning Light on page 3-47 for more information. In addition, if your vehicle has a Driver Information Center (DIC), the LOW WASHER FLUID message will display when the fluid level is low. See DIC Warnings and Messages on page 3-58 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. 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 the washer fluid tank only three-quarters full when it is very cold. This allows for fluid 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 the vehicle's windshield washer system and paint. 5-45
