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
> Trunk lid >
Fuel filler flap
> Convertible: glove compartment
Operating from outside
>Via the remote control
> Using the door lock
> In cars with Comfort Access, via the handles
on the driver's door and the front passenger
door
At the same time as locking and unlocking via
the remote control:
> Welcome lights, the inte rior light, and the
courtesy lighting are switched on and off.
> Alarm system, refer to page 32, is armed or
disarmed.
Operating from inside
By means of the button fo r central locking, refer
to page 29.
In the event of a sufficien tly severe accident, the
central locking system un locks 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 th e remote control with
you when you leave the ve hicle so that the latter
can be opened from outside. <
Convertible: to oper ate the retractable
hardtop with the remote control, the
doors and trunk lid must be closed and the
cargo area partition must be folded down and
engaged on both sides. Refer also to page39.<
Unlocking
Press the button.
The interior lamps, the courtesy lighting of the
doors, and the welcome lamps come on.

Air distribution
Direct the flow of air to the
windows , to the upper body
area or to the footwell . Inter-
mediate settings are possible. In
the center position between and , the air
is also deflected at toward the windows.
Recirculated air mode
If the air outside the car has an
unpleasant odor or contains pollut-
ants, shut off th e 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 the windows fog in recirculated air
mode, switch off the recirculated air
mode and increase the ai r volume if necessary.
The recirculated air mode should not be used over an extended period of time; otherwise, the
air quality in the passenger compartment will
deteriorate continuously.
<
Air volume
Turn to adjust the air volume. The
higher the volume, the more effec-
tive the heating or cooling will be.
The air flow rate is lowered or
switched off entirely to reduce the drain on the
battery.
Switching the system on/off
Set any desired air volume to switch on the air
conditioner.
Turn the air volume rotary switch to 0. The
blower and air conditioner are completely
switched off and the air supply is cut off.
The outside air supply is blocked when
the air conditioner is switched off. If the air
quality deteriorates or the window fogs over,

switch the system back on and increase the air
volume.<
Switching cooling function on/off
The cooling function cools and
dehumidifies the incoming air
before reheating it according to the
temperature setting. This function
is only available while the engine is running.
The cooling function helps prevent condensa-
tion on the windows or removes it quickly.
The cooling effect can be intensified by activat-
ing recirculated air mode.
Depending on the weathe r, the windshield may
fog over briefly when the engine is started.
Rear window defroster
The defroster is switched off auto-
matically after a certain time.
Depending on your vehicle's
equipment, the upper wires serve
as an antenna and are not part of the rear win-
dow defroster.
Temperature
To increase the temperature, turn
the rotary switch clockwise
towards red.
For a lower temperature, turn the
rotary switch counterc lockwise towards blue.

Ventilation
1 Use the thumbwheels to smoothly open
and close the air vents
2 Use the levers to change the direction of the
airflow
Ventilation for cooling
Adjust the vent outlets to direct the flow of cool
air in your direction, e.g. if it has become too hot
in the car.
Draft-free ventilation
Adjust the vents to let the air flow past you.
Microfilter
The microfilter removes dust and pollen from
the incoming air. Your BMW center replaces the
microfilter during routine maintenance.

Comfortable interior climate
AUTO program 5 offers the ideal air distribution
and air volume 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 page 25.
Adjusting air distribution manually
The air distribution can be
switched on and off manually. The
air is directed to the windshield, to
the upper body area and to the
footwell.
The automatic air distribu tion can be switched
back on by pressing the AUTO button. The
cooling function is swit ched on automatically and the manual air distribution setting is
cleared.
Temperature
Turn to set the desired tempera-
ture.
The automatic climate control
achieves this temperature as
quickly as possible rega rdless of the season,
using maximum cooling or heating power if nec-
essary, and then maintains it.
Avoid rapid switching between different tem-
perature settings. The automatic climate con-
trol will not have sufficien t time to adjust the set
temperature.
Maximum heating power can be obtained with
the highest setting, regardless of the outside
temperature.
The system cools steadily in the lowest setting,
regardless of the outside temperature.

Controls
Maximum cooling
Press the button.
The system is set to the lowest
temperature, maximum air volume
and recirculated air mode.
Air flows out of the vent outlets for the upper
body region. Open them for this purpose.
Air is cooled as quickly as possible:
> Above an outside temperature of approx.
327/06
> When the engine is running
AUTO program
Press the button.
Air volume, air distribution and
temperature are controlled auto-
matically.
Depending on the selected temperature, AUTO
intensity and outside in fluences, the air is
directed toward the wi ndshield, the side win-
dows, the upper body and the footwell.
Pressing the AUTO button automatically
switches on the cooling function.
At the same time, a co ndensation sensor con-
trols the program so as to prevent window con-
densation as much as possible.
The program is switched off when the air distri-
bution is set manually or the button is pressed
again.
Intensity of the AUTO program
With the AUTO program switched on, auto-
matic control of the air volume and air distribu-
tion can be adjusted:
Press the left side of the button to
reduce the intensity. Press the
right side of the button to
increase it.
The selected intensity is shown on the display
of the automatic climate control.
Convertible program
The Convertible program is active when the
hardtop is open. In the Convertible program, the
automatic climate control is optimized for driv-
ing with the hardtop open . In addition, the air
volume is increased as vehicle speed increases.
The effectiveness of the Convertible pro-
gram can be enhanced considerably by
installing the wind deflector.<
Adjusting air volume manually
To be able to manually adjust the air volume,
switch off the AUTO program first.
Press the left side of the button to
reduce the air volume. Press the
right side of the button to
increase it.
The air flow rate is lowered or switched off
entirely to reduce the drain on the battery. The
display remains the same.
Automatic recirculated air control
AUC/Recirculated air mode
You can respond to unpl easant odors or pollut-
ants in the immediate environment by tempo-
rarily suspending the supply of outside air. The
system then recirculates the air currently within
the vehicle.
Press the button repeatedly to
select an operating mode:
> LED off: outside air flows in continuously.
> Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air and
controls the shut-off automatically.
> Right-hand LED on, re circulated air mode:
the supply of outside air is permanently
shut off. If the windows fog over, switch off
recirculated air mode and increase the air
volume, if necessary. Make sure that air can
flow onto the windshield.

sation from the windshield and
front side windows.
For this purpose, also switch on the cooling
function.
Switching cooling function on/off
The passenger compartment can only be
cooled while the engine is running.
Press the button.
The air is cooled and dehumidified
and – depending on the tempera-
ture setting – warmed again.
Depending on the weather, the windshield may
fog up briefly when the engine is started.
Pressing the AUTO button automatically
switches on the cooling function.
Rear window defroster
