Condensation forms during opera-
tion of the air conditioning system,

which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.

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
remains on. The rear window defroster
switches off automatically after a short
while.

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.
39

7/+46.

Draft-free ventilation

You can adjust the blower controls for
the upper body area to obtain the opti-
mum airflow rates and directions for

the vents at any setting desired

3 With the rotary dial, you can add

more or less cool air to the air coming
from the outlets for the upper body
