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.

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.

Press the button repeatedly to select 
one of three different operating modes.
> Indicator lamps off: outside airflow is 

on

> Left indicator lamp on – AUC mode: 

the system recognizes pollutants in 
the outside air and blocks the flow of 
air when necessary. The system then 
recirculates the air currently within 
the vehicle. Depending on the air 
quality, the automatic system then 
switches back and forth between 
outside air supply and recirculation of 
the air within the vehicle

> Right indicator lamp on: the flow of 

external air into the vehicle is perma-
nently blocked. The system then 

recirculates the air currently within 
the vehicle.

If the windows should fog over in 
the recirculated-air mode, switch 

this mode off and increase the air sup-
ply as required.

<

When the rear window defroster 
is activated, the indicator lamp 

comes on. The rear window defroster 
switches off automatically.

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.

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

1 Rotary dials for infinitely variable 

opening and closing of the vent out-
lets

2 Levers for airflow direction

3 Rotary dial allows you to control the 

temperature of the airflow from these 
outlets as desired
