Caution: In freezing weather, do not use your washer until the windshield is warmed. Otherwise the washer fluid can form ice on the windshield, blocking your vision.

Pull the windshield wiper lever toward you to spray washer fluid on the windshield. The wipers will run for a few cycles to clear the windshield. For more wash cycles, pull the lever forward and hold.

Heated Windshield Washer Nozzles

This feature prevents the windshield washer fluid from freezing on the nozzle during cold conditions. The heated nozzles are turned on when the rear window defogger is activated. See Automatic Climate Control System.
