SWITCHES OUTSIDE REAR VIEW MIRROR DEFOGGER SWITCH CAUTION Since the mirror surfaces can get hot, do not touch them when the switch is on. If further defrosting or defogging is desired, simply actuate the switch again. When the surface has cleared, push the switch once again to turn the defogger off. Continuous use may cause the battery to discharge, especially during stop-and-go driving. The defogger is not designed to dry rain water or to melt snow. If the outside rear view mirrors are heavily coated with ice, use a spray de-icer before operating the switch. To turn the electric outside rear view mirror defogger on, push the switch. The ignition key must be in the "ON" position. The thin heater wires on the heater panels in the outside rear view mirrors will quickly clear the surface. Keep your hands off the mirror faces when the switch is on. An indicator light will illuminate to indicate the defogger is operating. The system will automatically shut off when the defogger has operated about 5 minutes. NOTICE To prevent the battery from being discharged, turn the switch off when the engine is not running. 47
