For 1990-2009 cars

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.

There is a button marked with the windshield washer symbol at the end of the windshield wiper lever. Press this button to spray washer fluid on the windshield. The wipers will run for a few cycles to clear the window and then either stop or return to your preset speed. For more wash cycles, press and hold the button longer.
