'07 HIGHLANDER HV_U (L/O 0608) On some models, the outside rear view mirror defoggers and/or the windshield wiper de−icer is also operating simultaneously by this switch. Vehicles with the outside rear view mirror defoggers, the heater panel in the outside rear view mirrors will quickly clear the surfaces. Vehicles with the windshield wiper de−icer, the windshield wiper blades will be de− iced. Push the switch once again to turn the defoggers off. The system will automatically shut off after the defogger has operated about 15 minutes. Make sure you turn the defoggers off when the surfaces are clear or the wiper blades have de−iced. Leaving the defoggers on for a long time could cause the 12 volt battery to discharge, especially during stop−and−go driving. The defoggers are not designed for drying rain water or for melting snow. If the outside rear view mirrors are heavily coated with ice, use a spray de−icer before operating the switch. NOTICE When cleaning the inside of the rear window, be careful not to scratch or damage the heater wires or connectors. CAUTION Vehicles with outside rear view mirror defoggers, since the mirror surfaces can get hot, do not touch them when the defogger switch is on. 140 2007 HIGHLANDER HV from July '06 Prod. (OM48685U)
