Maintenance and Specifications WINDSHIELD WASHER FLUID Windshield washer fluid Add fluid to fill the reservoir if the level is low. In very cold weather, do not fill the reservoir completely. Only use a washer fluid that meets Ford specification WSB-M8B16-A2. Refer to Lubricant specifications in the Capacities and specifications chapter. State or local regulations on volatile organic compounds may restrict the use of methanol, a common windshield washer antifreeze additive. Washer fluids containing non-methanol antifreeze agents should be used only if they provide cold weather protection without damaging the vehicle's paint finish, wiper blades or washer system. If you operate your vehicle in temperatures below 4.5° C (40° F), use washer fluid with antifreeze protection. Failure to use washer fluid with antifreeze protection in cold weather could result in impaired windshield vision and increase the risk of injury or accident. Do not put washer fluid in the engine coolant reservoir. Washer fluid placed in the cooling system may harm engine and cooling system components. Checking and adding washer fluid for the liftgate Washer fluid for the liftgate is supplied by the same reservoir as the windshield. 211
