Air conditioner
The air is cooled and dehumidi-
fied and Ð depending on the
temperature setting Ð rewarmed when
the air conditioner system is switched
on. Depending on the weather, the
windshield may fog over briefly when
the engine is started. Window mist will
be reduced by switching on the air
conditioner.
Condensation forms in the air
conditioning system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Automatic recirculated-air control
(AUC)
If there are unpleasant odors or
pollutants in the outside air, you
can temporarily block the air supply from
the outside. The system then recircu-
lates the air currently within the vehicle.
By repeatedly pressing the button, you
can select one of three different oper-
ating modes.
>Indicator lamps off: outside air always
flowing into the vehicle
>Left-hand indicator lamp on Ð auto-
matic mode: the system detects
pollutants in the outside air and
responds by deactivating the outside
air supply 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 air
supply 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. When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically.
The rear window defroster auto-
matically assumes operation
within 5 minutes after the engine is
started at outside temperatures below
40 7 (4 6).<
