07 SIENNA_U (L/O 0612) Push the switch once again to turn the defoggers off. The system will automatically shut off after the defoggers have operated about 15 minutes. 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. 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. 185 2007 SIENNA from Oct. '06 Prod. (OM45437U)
