'03 4Runner_U (L/O 0301) If the back window is not fully closed, the back window defogger will not work. Make sure the back window is fully closed when using the back window defogger. If the back window is opened while the defogger is working, the defogger will automatically turn off. Even if the back window is fully closed after that, the defogger will not automatically turn on. Make sure you turn the defoggers off when the surfaces are clear. 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. CAUTION On some models, since the mirror surfaces can get hot, do not touch them when the defogger switch is on. NOTICE When cleaning the inside of the back window, be careful not to scratch or damage the heater wires or connectors. 109 2003 4RUNNER from JAN. '03 Prod. (OM35806U)
