Ventilation
1Serrated dials for opening and closing the
air vents through an infinitely variable range
2Levers for changing airflow direction
3Serrated dial for more or less cool air from
the air vents for the upper body region,
independent of the temperature selected
on the rotary temperature control
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.

Please have your BMW Sports Activity
Vehicle Center work on lamps whose
replacement is not described here.<
Light-emitting diodes LEDs
Light-emitting diodes installed behind translu-
c e n t l e n s e s s e r v e a s t h e l i g h t s o u r c e f o r m a n y o f
the controls and displays in your vehicle. These
light-emitting diodes are related to ordinary
lasers.
Do not remove the covers, and never
stare into the unfiltered light for several
hours, as irritation of the retina could result.<
Xenon lamps*
The service life of these bulbs is very long and
the probability of failure is very low, provided
that they are not switched on and off an unusual
number of times. If one of these bulbs should
nevertheless fail, it is possible to continue driv-
ing with great caution using the fog lamps, pro-
vided traffic laws in your area do not prohibit
this.
To avoid risk of potentially fatal injuries
due to the extremely high voltages at
which these units operate, service work should
always be entrusted to qualified personnel.<
Halogen low beams
H7 bulb, 55 watts
Always wear gloves and eye protection –
the atmosphere inside the H7 bulb is
pressurized. Failure to observe this precaution
can lead to injuries should the bulb be dam-
aged.<
For checking and adjusting headlamp
aim, please contact your BMW Sports
Activity Vehicle Center.<
Driver's side
1.Position the screwdriver from the onboard
tool kit and pull off the lamp cover.
Exercise caution when handling the
screwdriver; otherwise, personal
injury can occur or the vehicle can be dam-
aged.<2.Press the bulb holder downward and
remove.
3.Remove the bulb, install a new bulb.
4.Place the bulb holder with the lower edge
against the bracket and press it in until the
lamp base locks into place.
Front passenger side
Before replacing the bulb, remove the reservoir
for the windshield washing system from the
bracket. To do so, unscrew the screws, refer to
arrow, using the screwdriver from the onboard
tool kit and set reservoir aside.
Bear in mind that the windshield washing
system reservoir is heavy. Failure to take
this into account can lead to personal injury or
damage to the vehicle.<
