blower, heating and air conditioner are
switched off, and the air supply is
stopped. You can reactivate the system
by pressing any button for the auto-
matic climate control.
Detailed setting options are described
for you in the following sections.
Temperature
The interior temperature that
appears in the display panel is a
general figure intended for reference
purposes. We recommend 727/+226
as a comfortable setting, even if the air
conditioning is on. When you start the
vehicle, the system ensures that the
selected temperature is reached as
quickly as possible. It then maintains
this temperature, regardless of the sea-
son.
You can make the settings of your
vehicle in such a manner that,
when you unlock the vehicle with the
remote control of your personal key,
your own personalized setting for the
automatic climate control is initiated.<
To defrost windows and remove
condensation
This program quickly removes
ice and condensation from the
windshield and the side windows.
Automatic air distribution and
supply
Air conditioning
The air is cooled and dehumidi-
fied and – depending on the
temperature setting – rewarmed.
The AUTO program adjusts the
air distribution and the air sup-
ply for you and in addition adapts the
temperature to external influences –
summer, winter – to meet preferences
you can specify.
To select the units of measure 6/7
of the display, refer to page 84.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started. Air conditioning helps
prevent the windows from fogging up.
Air supply/Blower
By pressing the left or right half
of the button, you can vary the
air supply. This deactivates the auto-
matic air supply – the AUTO display dis-
appears from the panel. Nevertheless,
the automatic air distribution remains
unchanged. You can reactivate the
automatic air supply by pressing the
AUTO button.
Individual air distribution
Condensation forms during opera-
tion of the air conditioning system,
which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
You can cancel the AUTO pro-
gram by selecting specific dis-
tribution patterns to suit your
own individual requirements.
While the AUTO program is then deacti-
vated, the automatic airflow control
remains in operation. Air flows onto

If the windows fog over in the
recirculated-air mode, switch the
recirculated-air mode off and increase
the air supply as required.<
Outside air/Automatic
recirculated-air control (AUC)/
Recirculated air
You can respond to unpleasant
external odors or pollutants by
temporarily stopping the flow of outside
air. The system then recirculates the air
currently within the vehicle.
Rear window defroster
With the convertible top closed
or with the hardtop* mounted,
press the button. The indicator lamp
remains on. The rear window defroster
switches off automatically.
By repeatedly pressing the button, you
can select one of three different operat-
ing modes.
>Indicator lamps off: outside air always
flowing into the vehicle
>Left-hand indicator lamp on – auto-
matic mode: the system detects pol-
lutants in the outside air and
responds by deactivating the outside
airflow as required. The system then
recirculates the air currently within
the vehicle.
You can have your vehicle pro-
grammed in such a way that the
rear window defroster switches on
automatically. This occurs within 5 min-
utes after starting the engine when out-
side temperatures are below approx.
397/+46.<
Draft-free ventilation
You can adjust the blower controls for
the upper body area to obtain the opti-
mum airflow rates and directions for
your personal requirements:
1 Rotary dials for opening and closing
the vents at any setting desired
2 Lever for adjusting airflow direction
Depending on air quality require-
ments, the system automatically
switches between outside air supply
and recirculation of the air already
within the vehicle
3 With the rotary dial you can adjust the
temperature of the outgoing air:
>Turn toward blue – colder
>Turn toward red – warmer
>Right-hand indicator lamp on: the
flow of outside air is permanently
blocked. The system recirculates the
air already within the vehicle.

Microfilter, activated-charcoal
filter
The built-in microfilter removes dust
and pollen from the incoming air. The
activated-charcoal filter provides addi-
tional protection by filtering gaseous
pollutants from the outside air. Your
BMW center will replace the combined
filter as a standard part of your sched-
uled maintenance. A substantial reduc-
tion in airflow indicates that the filter
needs to be replaced early.
