'01 HIGHLANDER_U (L/O 0106) To turn on the outside rear view mirror defogger and windshield wiper deicer, push the switch. The key must be in the "ON" position. The heater panel in the outside rear view mirrors will quickly clear the mirror surface. An indicator light is on when the defogger is operating. Type B only-The windshield wiper deicer is also equipped to deice the windshield wiper blades by operating simultaneously with the defogger. Push the switch once again to turn off the system. The system will automatically shut off after the system has operated about 15 minutes. Make sure you turn the system off when the mirror surfaces have cleared or the wiper blades have deiced. Leaving the system on for a long time could cause the battery to discharge, especially during stop−and−go driving. The defogger is 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 To prevent the battery from being discharged, do not operate the system continuously longer than necessary. CAUTION Since the mirror surfaces can get hot, keep your hands off them when the switch is on. 2001 MY HIGHLANDER_U (OM48432U) 97
