Outside air/Automatic
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

With the convertible top closed
or with the hardtop* mounted,

press the button. The indicator lamp

You can have your vehicle pro-

side temperatures are below approx.
