Heating and ventilation/Air conditioning1 Air onto the windshield and the side
windows
2 Air flow for the upper body
The rotary dials make it possible for
you to open and close the air supply
through an infinitely-variable range,
while the levers change the air-flow
direction. Refer to page 73

Heating and ventilation/Air conditioningAir supply
You can select blower speeds
from 1 to 4. The higher the set-
ting, the greater the amount of
heat and air supply. In position
0, the blower, heating and air condi-
tioner are switched off.
Temperature
In order to increase the inte-
rior temperature, turn to the
right. For rapid heating, turn
completely to the right. Then
select an interior temperature that is
comfortable for you.
Air distribution
You can direct the airflow onto
the windows , toward the
upper body and into the
footwell . You can also make
all intermediate settings. The "6 o'clock"
setting is recommended for normal con-
ditions (refer also to the illustration and
overview on page 70).
Recirculated air mode
If there are unpleasant odors
in the outside air, you can tem-
porarily block the air supply.
The system then recirculates
the air currently within the vehicle.
If the windows fog over when
using recirculated air, turn off the
recirculated air mode and increase the
airflow if necessary, or press the button
for "defrosting and defogging the win-
dows."<
Venting in outside air
Recommended when driving
with the convertible top open.
The degree to which the pas-
senger compartment is
heated depends on temperature selec-
tion and air distribution.
Air conditioner/Venting in outside
air
The air is cooled and dehu-
midified and Ð depending on
the temperature setting Ð
warmed again when the air
conditioner system is switched on.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started.
Do not turn on the air conditioner if out-
side air temperature is below approx.
41 7 (5 6). This will help to prevent
the windows from fogging.
If the windows fog over after switching
the air conditioner off, switch it back on.
Air conditioner/Recirculated air
mode
Both systems are operating.
Another advantage is that a
hot vehicle cools down more
quickly with the convertible
top closed. This way, you will get the
lowest possible vented air temperature
(turn the temperature rotary dial all the
way to the left).

To defrost windows and remove
condensation
This operation quickly re-
moves ice and condensation
from the windshield and the
side windows.
Rear window defroster
Whenever the hardtop is on,
the indicator lamp lights up
when the rear window de-
froster is turned on. The rear window
defroster switches off automatically.
Refer to page 58.
The indicator lamp is always
active. The rear window defroster
will not work if the hardtop is not in
place.<
Draft-free ventilation You can adjust the air outlets for the up-
per body area for your personal comfort:
Use rotary dials 1 to open and close the
air outlets through an infinitely-variable
range.520de043
You can adjust the direction of the air-
flow using the levers 2.
Set the air outlets so that the air flows
past you and is not directed straight at
you.MicrofilterThe microfilter removes dust and pollen
from the incoming air. Your BMW cen-
ter will change this filter during routine
maintenance. A substantial reduction in
air flow indicates that the filter needs to
be replaced early.520de140
