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.

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.

Microfilter
The microfilter removes dust and pollen from
the incoming air. Your BMW Center replaces
this filter during regular maintenance. A sub-
stantial reduction in air flow indicates that the
filter needs to be replaced earlier.

Comfortable interior climate
AUTO program 6 offers the ideal air distribution
and air flow rate for almost all conditions, refer
to AUTO program below. In addition, you can
select an interior temperature you find pleasant.
The following sections inform you in detail
about how to adjust the settings.
Air distribution, manual
Direct the flow of air to the windows
, to the upper body area and to
the footwell . Intermediate settings
are possible. The arrow lights up.
The automatic air supply remains unchanged.
You can switch the automatic air distribution
back on by pressing the AUTO button.
Defrosting windows and removing
condensation
Quickly removes ice and condensa-
tion from the windshield and side
windows.
AUTO program
The AUTO program adjusts the air
distribution to the windshield and
side windows, towards the upper
body area and into the footwell for
you. The air flow rate and your temperature
specifications will be adapted to outside influ-
ences as a result of seasonal changes, e.g. sun-
light or window condensation.
The cooling is switched on automatically with
the AUTO program.
The AUTO program functions only to a
limited extent when the convertible top is
open.<
Air flow rate, manual
Adjust the air flow rate. The arrow
lights up.
The automatic air distribution
remains unchanged. You can reactivate the
automatic mode for the air flow rate with the
AUTO button.The higher the air flow rate, the more effective
the air conditioning will be.
Switching the system on/off
Turn the rotary switch to 0. The automatic cli-
mate control is switched off and the air supply is
cut off.
To switch on the automatic climate control, set
any desired air flow rate.
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.
The cooling function is automatically switched
on along with the AUTO program. The passen-
ger compartment can only be cooled while the
engine is running.
Maximum cooling
At outside temperatures above
327/06 and when the engine is
running, you obtain a maximum cool-
ing effect as soon as possible.
The automatic climate control switches to the
lowest temperature and operates in recircu-
lated-air mode. Air flows at maximum rate only
from the vents for the upper body area. You
should therefore open them for maximum cool-
ing.
Temperature
Set the desired temperature.
The values on the dial are approxima-
tions of the respective temperature
resulting in the passenger compartment.
The automatic climate control achieves this
temperature as quickly as possible regardless
of the season, using maximum cooling or heat-
ing power if necessary, and then maintains it.
If you switch between different tempera-
ture settings in quick succession, the

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.<

The defroster switches off automati-
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.
