Air distribution
Direct the flow of air to the win-
dows 
, to the upper body area 
 or to the knee area and footwell 
. Intermediate settings are pos-
sible. In the 6 o'clock position, a small amount 
of air is also directed towards the windows in 
order to keep them from fogging over.
Recirculated-air mode
If the air outside the car has an 
unpleasant odor or contains pollut-
ants, shut off the supply to the interior of the car 
temporarily. The system then recirculates the 
air currently within the vehicle.
You can also activate/deactivate the recircu-
lated-air mode by means of a button
on the 
steering wheel, refer to page
.
If condensation starts to form on the 
inside window surfaces during operation 
in the recirculated-air mode, you should switch 
it off while also increasing the air flow rate as 
required. 
The recirculated-air mode should not be used 
continuously for lengthy periods, otherwise the 
quality of the air inside the car will gradually 
deteriorate.
<
Air flow rate
Press the corresponding button. 
The higher the rate, the more 
effective the heating or cooling 
will be.
The air flow rate may be reduced or the blower 
may be switched off entirely to save on battery 
power.
Switching the system on/off
With the blower at its lowest set-
ting, press the left side of the but-
ton. Thes blower and air condi-
tioner are completely switched off and the air 
supply is cut off.
To switch on the air conditioner, set the desired 
air flow rate.
Switching cooling function on/off
The cooling function cools and 
dehumidifies the incoming air 
before reheating it as required, according to the 
temperature setting. This function is only avail-
able while the engine is running.
The cooling function helps prevent condensa-
tion on the windows or removes it quickly.
Depending on the weather, the windshield may 
fog over briefly when the engine is started.
