4. Replace the cap and completely tighten it. 5. Then remove the cap again and look at the fluid level on the dipstick. The level should be between the ADD and FULL marks. If necessary, add only enough fluid to bring the level up to the proper range. Adding Washer Fluid 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. What to Use To determine what kind of fluid to use, see Recommended Fluids and Lubricants on page 6-12. Always use the proper fluid. Notice: Use of the incorrect fluid may damage your vehicle and the damages may not be covered by your warranty. Always use the correct fluid listed in Recommended Fluids and Lubricants on page 6-12. 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. 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. • 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. 5-37
