SWITCHES WINDSHIELD WIPER AND WASHER SWITCH To make the washer squirt, push the button on the end of the lever. Also, the wipers will automatically operate a couple of times after the washer squirts even with the lever in the "OFF" position. The low washer fluid warning light in the instrument cluster comes on when the fluid level in the tank becomes nearly empty. For information on adding washer fluid, see "Adding washer fluid" on page 230. In cold weather, warm the windshield with the defroster before using the washer. This will help prevent icing, which could block your vision. "
