Rear window heating
General notes
The rear window heating has a high current
draw. You should therefore switch it off as soon
as the window is clear. It otherwise switches off
automatically after several minutes.
If the battery voltage is too low, the rear window
heating may switch off.

Activating/deactivating air-recircula-
tion mode
General notes
You can deactivate the flow of fresh air tempo-
rarily if unpleasant odours are entering the vehi-
cle from outside. The air already inside the vehi-
cle will then be recirculated.
If you switch on air-recirculation mode, the win-
dows can mist up more quickly, in particular at
low temperatures. Only use air-recirculation
mode briefly to prevent the windows from mist-
ing up.
Switching on/off
