Without proper maintenance of visibility-related components, adverse weather conditions such as rain, snow and frost can seriously reduce visibility. Take time before winter arrives to check the following:
• Windshield Wipers ― Check windshield wiper operation and speeds. ― Inspect condition and travel of blades. Install new refills for any blades that are cracked, brittle, torn, or coated with road oil along the wiping edge.
• Windshield Washers ― Check operation of windshield washer. ― Inspect system hoses and replace if brittle or worn. ― Inspect washer reservoir. Drain and flush if dirt particles are evident in washer solution. ― Fill reservoir with commercially available non-freezing type washer fluid.
CAUTION Do NOT fill reservoir with water only. Even though non-freezing type washer fluid is recommended, do not attempt to clear the windshield of ice by activating the windshield washer and wipers. Ice accumulations should be removed manually by using a scraper.
