Problems with the rear window heating Problem
Possible causes/consequences and
M MSolutions The rear window heating

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 activate air-recirculation mode, the win-
dows can mist up more quickly, particularly at
low temperatures. Activate air-recirculation
mode only briefly to prevent the windows from
misting up.
The operation of air-recirculation mode is the
same for all control panels. Operating the climate control systems
