Vehicle Care What to Use To determine what kind of fluid to use, see Recommended Fluids and Lubricants on page 11‑7. Always use the proper fluid. Notice: Use of the incorrect fluid may damage the vehicle and the damages may not be covered by the vehicle's warranty. Always use the correct fluid listed in Recommended Fluids and Lubricants on page 11‑7. 10-23 Adding Washer Fluid When the windshield washer fluid reservoir is low, a WASHER FLUID LOW ADD FLUID message will be displayed on the Driver Information Center (DIC). See Washer Fluid Messages on page 5‑46 for more information. 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 the 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 the windshield washer. It can damage the windshield washer system and paint. . Washer Fluid What to Use When adding windshield washer fluid, be sure to read the manufacturer's instructions before use. If the vehicle will be operating in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing. Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview on page 10‑6 for reservoir location. . .
