CAUTION
Air distribution control
We recommend not smoking in the vehicle when the recirculating air opera-
tion is switched on. The smoke sucked from inside the vehicle is deposited on
the evaporator of the air conditioner. This produces a permanent odour when
the air conditioning system is operating which can only be eliminated through
considerable effort and expense (replacement of compressor).
The recirculation mode prevents contaminated outside air getting into the In-
terior of the vehicle. In recirculated air mode air is sucked out of the interior of
the vehicle and then fed back into the interior.
To switch on, press the button. The warning light below the button lights
up.

If the air distribution control is set to position when the recirculation modes
is switched on, the recirculated-air mode is switched off. By pressing the
button, the air recirculation also in this position can be switched on again.
When the cooling system ( button) is switched on and the temperature reg-
ulator is “turned” to the left, the recirculated-air mode is switched on.
Climatronic
The Climatronic can have a sensor that measures the air recirculation mode
and automatically turns on if there is an increased concentration of pollutants
in the incoming air.
The Air CareFunction reduces pollutant penetration contained in the outside
air into the vehicle.
When the function is activated, the air in the vehicle is circulated and cleaned
at the same time. The cleaning process is displayed by the zones displayed in
the Infotainment screen.
When the pollutant concentration decreases to the normal level, the recircula-
ted air mode is automatically switched off.
Automatic switch-on/switch-off of the air recirculation function can be set in
the Infotainment screen, by pressing the button on the Climatronic and by
To switch on/off, press the button on the Climatronic control panel, and

then pressing the function surface → Automatic air recirculation
.
A shut-off of the air recirculation function takes place automatically by press-
ing the button, possibly depending on the moisture conditions in the vehi-
cle interior.
To ensure correct Air Care functioning, all doors and windows including the
panoramic sliding/tilting roof must be closed.
When opening a door or a window, the corresponding message is displayed in
the Infotainment screen.
WARNING
The air recirculation cannot be switched on for a longer period of time be-
cause there is no supply of fresh air from the outside. “Stale air” may result
in fatigue in the driver and occupants, reduce attention levels and also
cause the windows to mist up. As soon as the windows mist up, turn the air
recirculation mode off immediately - there is a risk of accident!
