Air distribution
Direct the flow of air to the win-
dows , to the upper body area
or to the knee area and footwell
. Intermediate settings are pos-
sible. In the 6 o'clock position, a small amount
of air is also directed towards the windows in
order to keep them from fogging over.
Recirculated-air mode
If the air outside the car has an
unpleasant odor or contains pollut-
ants, shut off the supply to the interior of the car
temporarily. The system then recirculates the
air currently within the vehicle.
You can also activate/d eactivate the recircu-
lated-air mode by means of a button
* on the
steering wheel, refer to page 11.
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 the air flow rate as
required.
The recirculated-air mode should not be used
continuously for lengthy periods, otherwise the
quality of the air inside the car will gradually
deteriorate. <
Air flow rate
Press the corresponding button.
The higher the rate, the more
effective the heating or cooling
will be.
The air flow rate may be reduced or the blower
may be switched off entire ly to save on battery
power.
Switching the system on/off
With the blower at its lowest set-
ting, press the left side of the but-
ton. Thes blower and air condi-
tioner are completely switched off and the air
supply is cut off.
To switch on the air cond itioner, set the desired
air flow rate.
Switching cooling function on/off
The cooling function cools and
dehumidifies the incoming air
before reheating it as re quired, according to the
temperature setting. This function is only avail-
able while the engine is running.
The cooling function helps prevent condensa-
tion on the windows or removes it quickly.
Depending on the weathe r, the windshield may
fog over briefly when the engine is started.

Switching the cooling function
on and off
The cooling function cools and
dehumidifies the incoming air
before reheating it as required,
according to the temperature set-
ting. This function is only available while the
engine is running.
The cooling function he lps prevent condensa-
tion on the windows or removes it quickly.
Depending on the weathe r, the windshield may
fog over briefly when the engine is started.
The cooling function is automatically switched
on along with the AUTO program.
Maximum cooling
Maximum cooling is achieved most
quickly at outside temperatures
above 32 7/06 and when the
engine is running.
The automatic climate control goes into recir-
culated-air mode at the lowest temperature. Air
flows at maximum rate from the vents for the
upper body area. You should therefore open the
vents for maximum cooling.
AUTO program
The AUTO program auto matically adjusts the
air distribution to the windshield and side win-
dows, towards the upper bo dy area, and into the
footwell and knee area.
The air flow rate and air distribution, in addition
to your temperature specifications, will be
adapted to outside influenc es as a result of sea-
sonal changes, e.g. sunlight or window conden-
sation.
The cooling is switched on automatically with
the AUTO program.
Switching on/off
Press the button.
Manual air distribution and air flow rate are acti-
vated when the AUTO program is deactivated.
AUTO program climate level
The climate levels can be used to vary the inten-
sity when the AUTO program is switched on.
For example, air flow is adjusted automatically
to optimize climate control.
When the AUTO program is
switched on, you ca n select the cli-
mate level of the AUTO program
using the buttons for controlling the manual air
flow rate.
The selected climate le vel is displayed by
an LED.
Convertible program
When the hardtop is open, the convertible pro-
gram is activated as well. In the convertible pro-
gram, the automatic climate control is opti-
mized for driving with the hardtop open. In
addition, the air flow rate is increased as vehicle
speed increases.
The effectiveness of the convertible pro-
gram can be enhanced considerably by
installing the wind deflector. <
Adjusting air flow rate manually
Press the left side of the button to
reduce air flow. Press the right side
of the button to increase it.
The air flow rate may be reduced to save battery
power. The display remains the same.

Automatic recirculated-air control
AUC/recirculated-air mode
Switch on the desired operating
mode by pressing this button
repeatedly:
> LED off: outside air flows in continuously.
> Left-hand LED on, AUC mode: a sensor
detects pollutants in th e outside air. If nec-
essary, the system blocks the supply of out-
side air and recirculates the inside air. As
soon as the concentration of pollutants in
the outside air has decreased sufficiently,
the system automatically switches back to
outside air supply.
> Right-hand LED on, recirculated-air mode:
the supply of outside air is permanently
shut off. 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 the air flow rate as
required.
The recirculated-air mode should not be used
over an extended period of time, otherwise the
air quality inside the ca r will deteriorate contin-
uously. <
Defrosting windows and removing
condensation
Quickly removes ice and conden-
sation from the windshield and
front side windows.
Switch on the cooling function as well.
Rear window defroster
The defroster switches off auto-
matically after a certain time or

air vents.
3 Knurled wheel for adju sting the amount of
cool air from the vents to the upper body
area. In this way you can optimize the air
temperature for the upper body area.
Ventilation for cooling
Adjust the vent outlets to direct the flow of cool
air in your direction, for instance if it has become
too hot in the car.
Draft-free ventilation
Set the vent outlets so that the air flows past
you and not straight at you.
Microfilter/activated-charcoal filter
The microfilter traps dust and pollen in the
incoming air. The activated-charcoal filter pro-
vides additional protection by filtering gaseous
pollutants from the outs ide air. Your BMW cen-
ter replaces this combined filter during routine
maintenance.

The concept
Your BMW is equipped with a full preparation
package mobile phone.After pairing a suitable
mobile phone with the vehicle once, you can
operate the mobile phone via the iDrive, the
buttons on the steering wheel or using voice
commands
*.
Once a mobile phone has been paired with your
vehicle, it is automatically recognized as soon
as it is inside the vehicl e while the engine is run-
ning or the ignition is switched on. You can
store the pairing data for up to four mobile
phones simultaneously . If several mobile
phones are detected at the same time, the
mobile phone last paired can be operated via
the vehicle.
Using the telephone inside
the vehicle
Using the snap-in adapter*
The so-called snap-in adapter, a holder for
mobile phones, allows you to charge the mobile
phone's battery and connect the mobile phone
to your vehicle's outside antenna. This ensures
better network reception and consistent repro-
duction quality. Please contact your
BMW center to find ou t for which mobile
phones there are snap-in adapters available.
For your safety
A car phone makes life more convenient in
many ways, and can even save lives in an emer-
gency. While you should consult your mobile
phone's separate operating instructions for a
detailed description of safety precautions and
information, we request that you direct your
particular attention to the following:
Only make entries when the traffic situa-
tion allows you to do so. Do not hold the
mobile phone in your hand while you are driving;
use the hands-free system instead. If you do not observe this precau
tion, your being dis-
tracted can endanger vehicle occupants and
other road users. <
Suitable mobile phones
Please ask your BMW center which mobile
phones with Bluetooth interface are supported
by the mobile phone pr eparation package and
which mobile phones are compatible with the
snap-in adapter. By virtue of their particular
software versions, thes e mobile phones sup-
port the functions described in this Owner's
Manual. Malfunctions may occur with other
mobile phones.
