Central locking system
The concept
The central locking system functions when the
driver's door is closed.
The system simultaneously engages and
releases the locks on the following:
>Doors
>Luggage compartment lid
>Fuel filler flap
>Center armrest
*
Operating from outside
>Via the remote control
>Using the door lock
>In cars with Comfort Access
*, via the han-
dles on the driver's and passenger doors
In addition, if the remote control is used, the
welcome lamps, interior lamps and the door's
courtesy lamps
* are switched on or off. The
alarm system
* is also armed or disarmed.
For further details of the alarm system,
refer
to page33.
Operating from inside
By means of the button for central locking, refer
to page32.
In the event of a sufficiently severe accident, the
central locking system unlocks automatically. In
addition, the hazard warning flashers and inte-
rior lamps come on.
Opening and closing:
Using the remote control
Persons or animals in a parked vehicle
could lock the doors from the inside. You
should therefore take the remote control with
you when you leave the vehicle so that the latter
can be opened from outside.<
To operate the retractable hardtop with
the remote control, the doors and lug-
gage compartment lid must be closed and the
cargo area partition must be folded down and
engaged on both sides. Refer also to page38.<
Unlocking
Press the button.
The interior lamps, the courtesy lamps
* and the
welcome lamps come on.
Setting unlocking characteristics
You can set whether only the driver's door or
the entire vehicle is to be unlocked when the
button is pressed for the first time.

Air distribution
Direct the flow of air to the win-
dows , to the upper body area
o r to the kne e a rea and fo otwe ll
. 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/deactivate the recircu-
lated-air mode by means of a button
* on the
steering wheel, refer to page11.
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 entirely 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. The blower and air conditioner
are completely switched off and the air supply is
cut off.
To switch on the air conditioner, set the desired
air flow rate.
Switching cooling function on/off
The cooling function cools and
dehumidifies the incoming air
before reheating it as required, 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 weather, the windshield may
fog over briefly when the engine is started.

Comfortable interior climate
AUTO program7 offers the ideal air distribution
and air flow rate for almost all conditions, refer
to AUTO program below. All you need to do is
select an interior temperature which is comfort-
able for you.
The following sections inform you in detail
about how to adjust the settings.
Most settings are stored for the remote control
currently in use, refer also to Personal Profile
settings on page28.
Air distribution, manual
Depending on the selected setting, the air is
directed to the windshield, to the upper body
area, to the knee area and into the footwell.
Adjusting air distribution manually
Press the button repeatedly until
the air distribution is set as
required. The corresponding LED lights up.
The manual air distribution is also switched on
when the AUTO program is deactivated.
Temperature
Set the desired temperatures indi-
vidually for the driver's and pas-
senger sides.
The automatic climate control
achieves this temperature as quickly as possi-
ble regardless of the season, using maximum
cooling or heating power if necessary, and then
maintains it.
To give the automatic climate control
enough time to achieve the set tempera-
ture, do not switch between different tempera-
ture settings in quick succession.<
You can achieve maximum heating power with
the highest setting, regardless of the outside
temperature.
The lowest setting effects continuous cooling.

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 helps prevent condensa-
tion on the windows or removes it quickly.
Depending on the weather, 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 327/06 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 automatically adjusts the
air distribution to the windshield and side win-
dows, towards the upper body 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 influences as a result of sea-
sonal changes, e.g., sunlight or window con-
densation.
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 can select the cli-
mate level of the AUTO program
using the buttons for controlling the manual air
flow rate.
The selected climate level 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.
Switching the system on/off
With the blower at its lowest setting, press the
left side of the button to switch off the auto-
matic climate control. All displays are cleared
except for the rear window defroster if it is
switched on.
Press any button except the rear window
defroster to reactivate the automatic climate
control.

Climate

Residual heat
The heat stored in the engine is used to heat the
interior.
This function can be switched on
using the right button under the
following conditions:
>Up to 15 minutes after the engine has been
switched off
>While the engine is at operating tem-
perature
>As long as battery voltage is sufficient
>At an outside temperature below 777/
256
The middle LED is lit when the function is on.
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 the 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 car 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
when the hardtop is opened.
Ventilation
1Lever for changing the direction of the
air flow.
2Thumbwheels for opening and closing the
air vents.
3Thumbwheel for adjusting 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 outside air. Your BMW cen-
ter replaces this combined filter during routine
maintenance.
