Automatic recirculated air control/
recirculated air mode
You can respond to unpleasant
odors or pollutants in the immedi-
ate environment by temporarily
suspending the supply of outside air. The sys-
tem then recirculates the air currently within the
vehicle. In AUC mode, 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:
>LEDs off: outside air flows into the vehicle
continuously.
>Left LED on, AUC mode: the system
detects pollutants in the outside air and
responds by blocking the supply of outside
air when required.
>Right LED on, recirculated-air mode: the
supply of outside air into the vehicle is con-
tinuously blocked.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 quantity as needed.
The recirculated-air mode should not be used
over a longer period of time, as the air quality
inside the vehicle deteriorates continuously.<
Automatic climate control, switching
on and off
The air volume, the heater, and the
air conditioner mode are all
switched off.
You can restart the automatic climate control by
pressing any of its buttons except the REST
button.
Temperature adjustment
Adjust the desired temperature
individually on the driver's side and
passenger side. Your settings
appear on the status line of the
Control Display.
The automatic climate control achieves this
temperature as quickly as possible at any time
of year, if necessary with the maximum cooling
or heating capacity, and then keeps it constant.
When switching between different tem-
perature settings in rapid succession, the
automatic climate control does not have suffi-
cient time to achieve the set temperature.<
The highest setting switches on the maximum
heat output regardless of the outside tempera-
ture. The lowest setting activates maximum air
conditioning.
Using iDrive
1.Open the start menu.
2.Open "Climate".
3.Turn the controller to select driver's side or
passenger side.
4.Turn the controller to select the field and
press the controller.

Climate

6.Press the controller to save the setting.
Maximum cooling
Maximally cooled air is obtained as
quickly as possible at an outside
temperature of approx. 327/06
and with the engine running.
The automatic climate control
changes over to the lowest temperature and
switches into the recirculated-air mode. The
maximum air quantity only flows out of the vents
for the upper body. So open these vents for
maximum cooling.
Air volume
You can vary the air volume by
turning. You can reactivate the
automatic air supply mode by
pressing the AUTO button.
Manual air distribution
You can adapt the air distribution to your own
personal preferences:
1.Open the start menu.
2.Open "Climate".
3.Turn the controller to select driver's side or
passenger side.4.Select the desired field and press the con-
troller.

windows
2Air to the upper body
3Air to footwell
You can only use the condensation sensor in
the AUTO program. Press the AUTO button
when you notice condensation on windows and
wish to take advantage of the condensation
sensor.
Defrosting windows and removing
condensation
Quickly remove ice and condensa-
tion from the windshield and front
side windows.
Also switch on the air conditioner.
Residual heat
The system uses the warmth
stored in the engine to heat the
interior when the ignition is off, e.g.
while the vehicle is stopped at a
school to pick up a child.
The function can be switched on when the fol-
lowing conditions are met:
>up to 15 minutes after switching off the
engine
>with the engine at operating temperature
>with sufficient battery voltage
>at an outside temperature below 777/
256
The LED lights up when the function is
switched on.

The interior temperature, air volume, and air
distribution can be set starting from the radio
ready state.
Switching cooling function on and off
manually
When activated, the air conditioner
mode cools and dehumidifies the
incoming air, reheating it as
required, depending on the temperature set-
ting. Depending on the weather, the windshield
may fog over briefly when the engine is started.
The cooling function is switched on automati-
cally with the AUTO program. The passenger
compartment can only be cooled with the
engine running.
Rear window defroster
The rear window defroster
switches off automatically after a
while. Depending on your equip-
ment package, the upper wires are used as an
antenna and are not part of the rear window
defroster.
Front ventilation

tion
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, etc.
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 microfilter removes dust and pollen from
the incoming air. The activated-charcoal filter
provides additional protection by filtering gas-
eous pollutants from the outside air. Your BMW
center replaces this combined filter as a stan-
dard part of your scheduled maintenance.
You can select a display of more detailed infor-
mation in the service required display, refer to

ensures that the selected setting is achieved as
quickly as possible. It then maintains this tem-
perature, regardless of the season.
Air volume
You can vary the air volume by
turning.
Maximum cooling

maximum cooling.
The system automatically switches to the recir-
culated-air mode and the maximum air volume flows from the ventilation grilles. So open these
vents for maximum cooling.

Ventilation in rear
Use the lever1 to vary the airflow direction.
For additional information on rear ventilation
options, refer to page107.
Parked car ventilation
The parked car ventilation blows air into the
passenger compartment to reduce interior tem-
peratures.
You can set two different times for the system
to start. The system is operated via iDrive.
It remains switched on for 30 minutes.
Since the system uses a substantial amount of
electrical current, you should refrain from acti-
vating it twice in succession without allowing
the battery to be recharged in normal operation
between uses.
With a preselected switch-on time, the parked
car ventilation is switched on at an outside tem-
perature of 597/156 or greater. When oper-
ated manually, it is ready for use at any outside
temperature, but not during driving.
The air enters the passenger compartment
through the air vents for the upper body in the
dashboard, which can be adjusted for both
direction and airflow. These vents must be
open for the system to operate.
