Air distribution
You can direct airflow onto the
windows , toward the upper
body and into the footwell .
All intermediate settings are pos-
sible.
Air supply/blower
You can set the blower to 8 differ-
ent levels. Both heating and ven-
tilation become more effective as
the air supply rate is increased.
Turn the rotary control toward zero:
The blower and the heating are turned off,
and the air supply is stopped.
Temperature
In order to increase the tempera-
ture of the passenger compart-
ment, turn to the right toward the
red zone.
Air conditioning
The air is cooled and dehumidi-
fied and – depending on the tem-
perature setting – rewarmed.
Depending on the weather, the
windshield may fog over briefly when the
engine is started.
Condensation forms during operation
of the air conditioning system, which
then exits under the vehicle. Traces of con-
densed water on the ground underneath
the vehicle are thus normal.<
Outside-air/recirculated-air mode
If there are unpleasant odors in
the outside air, you can tempo-
rarily block the supply of incom-
ing air. The system then recircu-
lates the air currently within the vehicle.
If the windows fog over in the recircu-
lated air mode, switch this mode off
and increase the air supply as required. Do
not use the recirculated-air mode continu-
ously over a long period of time as this
would otherwise reduce the air quality in
the interior of the vehicle.<
Rear window defroster
The indicator lamp lights up when
the rear window defroster is
active. The rear window defroster
switches off automatically.
Ventilation
You can adjust the blower controls for the
upper body area to obtain the optimum air-
flow rates and directions for your personal
requirements:
1Rotary dials for opening and closing the
vents at any setting desired
2Slide for adjusting airflow direction
Microfilter
The built-in microfilter removes dust and
pollen from the incoming air and in the
recirculated air mode. Your BMW center
will replace this filter during the regularly
scheduled maintenance. A substantial
reduction in airflow indicates that the filter
needs to be replaced earlier.

Tips for pleasant driving
Use the automatic system – switch on with
AUTO button 6. Select the desired interior
temperature.
Detailed setting options are described for
you below.
Automatic air distribution and supply
The AUTO program assumes the
adjustment of the air distribution
and air supply for you and in addi-
tion adapts the temperature to
external influences, summer or winter, to
meet preferences you can specify.
In the AUTO program, the air conditioning
mode is also turned on at the same time.
The AUTO program functions only to
a limited extent when the convertible
top is open.<
Individual air distribution
You yourself can direct airflow
onto the windows , toward the
upper body and into the foot-
well . The arrow lights up. The
automatic air supply remains unchanged.
All intermediate settings are possible. By
pressing the AUTO button, you can reacti-
vate the air distribution.
Temperature
The interior temperature that
appears on the display panel is a
general figure intended for refer-
ence purposes. When you start
the vehicle, the system ensures that the
selected temperature is reached as quickly
as possible, regardless of the season. It
then maintains this temperature.
Air supply/blower
You can set the blower through
an infinitely variable range of
speeds. This shuts off the auto-
matic air supply. The arrow lights
up. The automatic air distribution remains
unchanged. You can reactivate the auto-
matic air supply by pressing the AUTO but-
ton.When you turn the rotary control toward
zero: the blower, heating and air condi-
tioner are switched off, and the air supply is
stopped. You can reactivate the system by
turning the control toward the right again.
To defrost windows and remove
condensation
This program quickly removes ice
and condensation from the wind-
shield and the side windows.
Maximum cooling
Above an outside temperature of
417/+56 and with the engine
running, you achieve a maximum
cooling effect as quickly as possi-
ble. At the same time, the air conditioning is
turned on.
The temperature is set to the lowest possi-
ble value. The system switches into the
recirculated air mode and air flows at max-
imum blower speed from the air outlets
only. Therefore, the air outlets must always
be open when you select this program.
Air conditioning
The air is cooled and dehumidi-
fied and, depending on the tem-
perature setting, rewarmed.
Depending on the weather, the
windshield may fog over briefly when the
engine is started.
The air conditioning system is automati-
cally switched on when you use the AUTO
program.
Condensation forms during operation
of the air conditioning system, which
then exits under the vehicle. Traces of con-
densed water on the ground underneath
the vehicle are thus normal.<
