Rear window defogger NOTICE z z To prevent the battery from being discharged, turn the switch on when the engine is running. When cleaning the inside of the rear window, be careful not to scratch or damage the heater wires. 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 surface. An indicator light will illuminate to indicate the defogger is operating. Push the switch once again to turn the defogger off. Make sure you turn the defogger off when the window is clear. Leaving the defogger on for a long time could cause the battery to discharge, especially during stop-andgo driving. The defogger is not designed for drying rain water or for melting snow. 68
