Air conditioning for comfortUse the automatic system; switch on
AUTO key1. Select the interior temper-
ature that is comfortable for you, e.g.,
70 5F (226). With exterior temperatures
above 41 5F (56) you can also use air-
conditioning 6. This dries the air and
prevents window mist when e.g., per-
sons with damp clothing are in the vehi-
cle. Adjust vent 2 in such a way that the
air blows past you and does not strike
you directly. Turn the rotary control on
the left under the vents 2 for the upper
body area to a middle setting, so that
you will be driving in cooler air that
does not tire you out.
The following description gives you
additional individual settings.
Automatic air distribution

When you activate the AUTO
mode, the program takes
over the setting of the air distribution
and the air supply and, in addition,
adjusts your temperature pre-selections
to exterior conditions (summer, winter).
This program maintains a comfortable
in-car climate regardless of the season.
Select the interior temperature that is
comfortable for you, e.g., 70 5F (226).
The temperature pre-selections as well
as the lettering AUTO for the air supply
appear in indicator 3.
Open the vent outlets for the upper
body area. Switch on the air conditioner
in warm weather.
The maximum cooling capacity is
achieved when you set the rotary dial 3
(refer to page 92) to cold.
You can cancel the automatic
program by selecting distri-
bution patterns to suit your
individual requirements. You
can direct air toward the windshield and
windows 7, toward the upper body
5
and/or into the footwell
6.

*
Press the button repeatedly to run
through the following control sequence:
dIndicator lamps off: outside air flow
operational.
dLeft-hand indicator lamp on Ð AUC
mode: the system detects pollutants
in the outside air and responds by
deactivating the outside air flow as
required. The system then recircu-
lates the air currently within the vehi-
cle.
dRight-hand indicator lamp on: the
flow of outside air into the vehicle is
permanently blocked. The system
then recirculates the air currently
within the vehicle.a
If the windshields fog over in circu-
lated air mode, switch off the circulated
air mode/Automatic recirculated air
control and increase the air supply. if
necessary.c

The rear-window blower is always
switched off with the convertible top
down.
When the hardtop

the rear-window heating button.
Temperature
This program is designed for
rapid removal of ice and con-
densation from the windshield and side
windows.
The air conditioner cools and
dehumidifies incoming air
before reheating it to the selected tem-
perature.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started.
Switching off the air conditioner at out-
side temperatures below approx. 41 5F
(56) will prevent the windows from
fogging up.
Frequently switching the air condi-
tioner on and off may also promote the
formation of condensation on the win-
dow surfaces.
b
Condensation forms in the air
conditioner system during operation,
which then exits under the vehicle. It is
not unusual for a small puddle to form
there.c
You can respond to unpleas-
ant odors in the outside air
by temporarily excluding the outside air.
The system then recirculates the air
currently within the vehicle.
A
The indicator lamp comes
on to confirm that the rear
defroster is operating.
The defroster switches off automatically
after approx. 15 minutes.
On both the driver's and the
passenger's side you can
adjust the specific temperature. The fig-
ures in the display provide a general
indication of interior temperature. We
recommend 70 5F (226) as a standard
setting for comfortable travel, both with
and without the air conditioner. When
you start the vehicle, the system
ensures that the selected temperature
is achieved as quickly as possible and
maintained at a constant level by the
control.

Air supply
Draft-free ventilation
You can adjust the vent outlets for the
upper body area to select the optimum
airflow rates and directions for your
own personal requirements:
Use rotary controls 1 to open and close
the vents throughout and infinitely-vari-
able range. Use the levers 2 to adjust
the direction of the air flow.
The rotary control 3 allows you to mix
the air from the outlets for your upper
body by warming or cooling it as
desired:
Turn toward blue Ð colder
Turn toward red Ð warmer
MicrofilterThe microfilter removes dust and pollen
from the incoming air. The filter is
changed by your BMW Retailer when
you bring your vehicle for maintenance.
A substantial reduction in air flow indi-
cates that the filter needs to be
replaced prematurely. In the AUTO mode, the air
supply is controlled automat-
ically and AUTO appears in display 3,
refer to the summary on page 90. Using
"+" and "Ð" you can vary the air flow.
Your setting is indicated by bars, the
automatic control is switched off. You
can reactivate it by pressing the AUTO
key.
When you press "-" during operation at
minimum blower speed all displays are
canceled: the fan, heating and air con-
ditioner are switched off, the air supply
is blocked. By pressing on any key of
the air conditioning you can again
engage the system.
Effective heating and cooling is ensured
at a medium blower speed.
