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.

condensation
1.Air distribution1 in position .
2.Set air flow rate 2 to position 4.
3.Temperature3 to the right, red.
4.Switch on rear window defroster 4 to
defrost the rear window.
Ventilation
1Knurled wheels to set any vent position
from fully open to closed
2Slide 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.

automatic climate control does not have
enough time to achieve the set temperature.<
AUC Automatic recirculated-air
control/Recirculated-air mode
Switch on the desired operating
mode by pressing this button repeat-
edly:
>LEDs off: outside air flows in continuously.
>Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air. If nec-
essary, the system blocks the supply of out-
side air and recirculates the inside air. As
soon as the concentration of pollutants in
the outside air has decreased sufficiently,
the system automatically switches back to
outside air supply.
>Right-hand LED on, recirculated-air mode:
the inflow of outside air is shut off perma-
nently. 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 recirculated-air mode should not be used
over an extended period of time, otherwise the
air quality inside the car will deteriorate contin-
uously.<

cally after a certain time.

Microfilter/activated-charcoal filter
The microfilter removes dust and pollen from
the incoming air. The activated-charcoal filter
provides additional protection by filtering gas-
eous pollutants from the outside air. Your BMW
Center replaces this combined filter during reg-
ular maintenance. A substantial reduction in air
flow indicates that the filter needs to be
replaced earlier.
