Ventilation
1Knurled wheels for opening and closing the
air vents through an infinitely variable range
2Levers for changing airflow direction
3Knurled wheel for more or less cool air from
the air vents for the upper body region
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
The microfilter removes dust and pollen from
the incoming outside air. It is replaced when
maintenance is performed by your BMW Sports
Activity Vehicle Center. A substantial reduction
in air supply indicates that the filter should be
replaced before normal maintenance.

AUC Automatic Recirculated-air
Control/recirculated air mode
You can set the desired operating
mode by pressing the button
repeatedly:
>LEDs off: outside air continuously flows into
the vehicle.
>Left LED on, AUC mode: a sensor detects
pollutants in the outside air. The system
suspends the supply of outside air as
needed and recirculates the air currently
within the vehicle. As soon as the concen-
tration of pollutants in the outside air has
decreased sufficiently, the system switches
automatically back to supplying outside air.
>Right LED on, recirculated-air mode: the
outside air supply into the vehicle is shut off
continuously. The system then recirculates
the air currently within the vehicle.
If the windows fog over in recirculated-air
mode, then press the AUTO button or
switch off the recirculated air mode and
increase the air volume as needed.
The recirculated-air mode should not be used
over a sustained period of time; otherwise, the
air quality inside the vehicle will steadily deteri-
orate.<
Rear window defroster
The rear window heating switches
off automatically after a certain
amount of time. Depending on
your equipment package, the upper wires are
used as an antenna and are not part of the rear
window defroster.

Microfilter/activated-charcoal filter*
The microfilter removes dust and pollen from
the incoming outside air. The activated-char-
coal filter provides additional protection by fil-
tering gaseous pollutants from the outside air.
This combined filter is replaced when mainte-
nance is performed by your BMW Sports Activ-
ity Vehicle Center. A substantial reduction in
air supply indicates that the filter should be
replaced before normal maintenance.
