Windshield Washers RESERVOIR CAP Check the reservoir's fluid level by removing the cap and looking at the level gauge attached to the cap. Fill the reservoir with a good-quality windshield washer fluid. This increases the cleaning capability and prevents freezing in cold weather. When you refill the reservoir, clean the edges of the windshield wiper blades with windshield washer fluid on a clean cloth. This will help to condition the blade edges. NOTICE Check the level in the windshield washer reservoir at least monthly during normal usage. In bad weather, when you use the washers often, check the level every time you stop for fuel. The windshield washer reservoir is located in the rear of the engine compartment on the passenger's side. Do not use engine antifreeze or a vinegar/water solution in the windshield washer reservoir. Antifreeze can damage your car's paint, while a vinegar/water solution can damage the windshield washer pump. Use only commercially-available windshield washer fluid. Maintenance
