04 SIENNA_U (L/O 0408) Rear window and outside rear view mirror defoggers and windshield wiper de −icer Push the switch once again to turn the defoggers off. The system will automatically shut off after the defoggers have operated about 15 minutes. CAUTION On some models, since the mirror surfaces can get hot, do not touch them when the defogger switch is on. 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 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. To defog or defrost the rear window, push the switch. The key must be in the "ON" position. The thin heater wires on the inside of the rear window will quickly clear the window surfaces. An indicator light will illuminate to indicate the defogger is operating. On some models, the 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. NOTICE When cleaning the inside of the rear window, be careful not to scratch or damage the heater wires or connectors. 161 2004 SIENNA from Aug. '04 Prod. (OM45422U)
