10-22 Vehicle Care Washer Fluid What to Use When windshield washer fluid is needed, be sure to read the manufacturer's instructions before use. If operating the vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing. . { Caution Do not use engine coolant (antifreeze) in the windshield washer. It can damage the windshield washer system and paint. 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. When using concentrated washer fluid, follow the manufacturer instructions for adding water. 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. Brakes This vehicle has disc brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound can come and go or be heard all the time when the vehicle is moving, except when applying the brake pedal firmly. . Adding Washer Fluid . { Warning The brake wear warning sound means that soon the brakes will not work well. That could lead to a crash. When the brake wear warning sound is heard, have the vehicle serviced. . Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview on page 10-5 for reservoir location. { Caution Continuing to drive with worn-out brake pads could result in costly brake repair.
