SWITCHES 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 293. In cold weather, warm the windshield with the defroster before using the washer. This will help prevent icing, which could block your vision. REAR WINDOW AND OUTSIDE REAR VIEW MIRROR DEFOGGER SWITCH NOTICE Do not operate the wipers if the windshield is dry. It may scratch the glass. To turn the electric rear window defogger on, push the switch. The ignition key must be in the "ON" position. The thin heater wires on the inside of the rear window and the heater panels in the outside rear view mirrors will quickly clear the surface. An indicator light is on when the defogger is operating. The system will automatically shut off when the defogger has operated about 15 minutes. 23
