For 1990-2009 cars only

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.

(Washer Fluid): Pull the lever towards you to spray water onto the windshield. Washer fluid will squirt onto the windshield and the wipers will run for a few cycles to clear the windshield.
