Automatic recirculation
If the outside air is polluted, an air purity sensor in the
vehicle will automatically switch on the air recirculation.
Applies to vehicles: with deluxe automatic air conditioner plus
General notes
To prevent fumes, etc. in the outside air from entering the interior,
we recommend that the automatic air recirculation should be
switched on at all times.
The basic settings for the air conditioner can be adjusted
via the sound system or MMI*.
If the air purity sensor in the air conditioner system detects a certain
concentration of fumes in the outside air, the control unit will either
pass the incoming air through the pollution filter or automatically
switch on the air recirculation. If there is a high concentration of
pollution in the outside air, the air conditioner automatically
switches to air recirculation and cuts off the supply of air from the
outside. As soon as the level of pollution decreases, air is fed into
the vehicle from the outside again.
If the windows mist up when the automatic air recirculation is on,
press the button immediately.

Setup AC
The automatic air recirculation can switch itself off in certain condi-
tions. If the outside temperature is less than about +10 °C, the auto-
matic air recirculation will only operate for 30 seconds. If the air
conditioner is switched to the ECON mode, or if the outside temper-
ature is less than about -1 °C, the automatic air recirculation will
only operate for 15 seconds.
