Switching air-recirculation mode
on/off
General notes
You can also temporarily deactivate the flow of
fresh air manually if unpleasant odours are
entering the vehicle from outside. The air
already inside the vehicle will then be recircula-
ted.
If you activate 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 misting up.
