Press the switch to turn on the electric rear window defroster. The electric heater turns on for about 10–15 minutes and then turns off automatically. When the electric heater is operating, the corresponding indicator lights up (pic. 1.72).
To forcibly turn off the electric heater before 10–15 minutes have elapsed, press the switch again.
Attention! The electric rear window defroster is not designed to remove snow from the glass. If there is snow on the rear window, then before turning on the electric heater, it is necessary to clear the glass of snow manually.
