culates the air currently within the vehicle.
During AUC operation, a sensor detects pollut-
ants in the outside air and controls the shut-off
automatically.
Press the button repeatedly to run through the
following control sequence:
>
Indicator lamps off: outside air flows into the
vehicle.
>
Left indicator lamp on, AUC mode: the sys-
tem recognizes pollutants in the outside air
and blocks the flow of air when necessary.
The system then recirculates the air cur-
rently within the vehicle. Depending on the
air quality, the automatic system then
switches back and forth between outside air
supply and recirculation of the air within the
vehicle.
>
Right-hand indicator lamp on: the outside
air supply into the vehicle is shut off contin-
uously. The system then recirculates the air
currently within the vehicle.
If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing air supply as
required. The recirculated-air mode should not
be used over a sustained period of time, other-
wise the air quality inside the vehicle will deteri-
orate.
<
Rear window defroster
When the rear window defroster is
activated, the indicator lamp
comes on. The rear window
defroster switches off automatically.
You can have your vehicle set so that the
rear window defroster switches on auto-
matically. It is then switched on at outside tem-
peratures of less than approx. +39
7/+46
within 5 minutes of the engine start.

Ventilation
The air vents for the upper body area can be
adjusted:
1 Serrated dials
Serrated dials for opening and closing the
vent outlets through an infinitely-variable
range.
2 Levers
Selector levers for airflow direction.
3 Serrated dial
Use this serrated dial to adjust the amount
of cool air that is added to the airflow
emerging from the vent outlets for the
upper body.
Ventilation for cooling
Adjust the vents to direct the flow of cool air in
your direction, for instance, if the interior has
become too warm.
Draft-free ventilation
Set the vent outlets so that the air flows past
you and is not directed straight at you.
Microfilter/activated-charcoal filter*
The built-in microfilter removes dust and pollen
from the incoming air. The activated-charcoal
filter provides additional protection by filtering
gaseous pollutants from the outside air. This
combined filter is replaced when maintenance
is performed by your BMW Sports Activity Vehi-
cle Center. A substantial reduction in air supply
indicates that the filter should be replaced
before normal maintenance.
