Air distribution
Direct the flow of air to the windows
, to the upper body area and to
the footwell . Intermediate settings
are possible.
Switching cooling function on/off
When the cooling function is on, the
air is cooled, dehumidified, then
reheated depending on the tempera-
ture setting.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
Recirculated-air mode
If the air outside the car has an
unpleasant odor or contains pollut-
ants, temporarily shut off the supply
to the interior of the car. The system
recirculates the air within the vehicle.
If the windows fog over in the recircu-
lated-air mode, you should switch it off
and, if necessary, increase the air flow rate.
The manually controlled recirculated-air mode
should not be used continuously for lengthy
periods, otherwise the quality of the air inside
the car will gradually deteriorate.
<
Temperature
For a higher temperature, turn the
rotary switch clockwise towards red.
For a lower temperature, turn the
rotary switch counterclockwise
towards blue.
Air flow rate
Adjust the air flow rate. The higher
the rate, the more effective the heat-
ing or cooling will be.
Switching the system on/off
Set the air flow rate to 0. Blower and air condi-
tioning are switched off and the air supply is cut
off.
To switch on the heater or air conditioning, set
any desired air flow rate.
Rear window defroster
The defroster switches off automati-
cally after a certain time.
Defrosting windows and removing
condensation
1. Air distribution 1 in position .
2. Set air flow rate 2 to position 4.
3. Temperature 3 to the right, red.
4. Switch on rear window defroster 4 to
defrost the rear window.
Ventilation
1 Knurled wheels to set any vent position
from fully open to closed
2 Slide for adjusting air flow direction
Ventilation for cooling
Adjust the vent outlets to direct the flow of cool
air toward you, for instance if it has become too
hot in the car.
Draft-free ventilation
Set the vent outlets so that the air flows past
you and not straight at you.
