Windshield Washers 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 gas. The windshield washer reservoir is located behind the left headlight. Check the reservoir's fluid level by removing the cap and looking inside. Fill the reservoir with a goodquality windshield washer fluid. This increases the cleaning capability and prevents freezing in cold weather. 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. NOTICE Do not use engine antifreeze or a vinegar/water solution in the windshield washer reservoir. Maintenance
