recirculated-air control (AUC)/
Recirculated air
You can respond to unpleasant
external odors or pollutants by
temporarily stopping the flow of outside
air. The system then recirculates the air
currently within the vehicle.
By repeatedly pressing the button, you
can select one of three different operat-
ing modes.
>
Indicator lamps off: outside air always
flowing into the vehicle
>
Left-hand indicator lamp on – auto-
matic mode: the system detects pol-
lutants in the outside air and
responds by deactivating the outside
airflow as required. The system then
recirculates the air currently within
the vehicle.
Depending on air quality require-
ments, the system automatically
switches between outside air supply
and recirculation of the air already
within the vehicle
>
Right-hand indicator lamp on: the
flow of outside air is permanently
blocked. The system recirculates the
air already within the vehicle.
If the windows fog over in the
recirculated-air mode, switch the
recirculated-air mode off and increase
the air supply as required.

Rear window defroster
When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically after a short

You can have your vehicle pro-
grammed in such a way that the
rear window defroster switches on
automatically. This occurs within 5 min-
utes after starting the engine when out-
side temperatures are below approx.
