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.

NOTICE When cleaning the inside of the rear window, be careful not to scratch or damage the heater wires. 101
