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
>Via the door lock
*
>In cars with Comfort Access*, via the
handles on the driver's and front 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
page32.
Operating from inside
By means of the button for central locking,
refer to page30.
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.<
Convertible: to operate 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 lamps
* and the
welcome lamps come on.

Automatic climate control
Comfortable interior climate
AUTO program7 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 page26.
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 distribution can be switched
back on by pressing the AUTO button. The
cooling function is switched 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 regardless 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 sufficient 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.
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 influences, the air is
directed toward the windshield, 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 condensation 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 and the AUTO program is
switched on. 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 volume may be reduced or the blower
may be switched off entirely to save on battery
power. The display remains the same.
Automatic recirculated-air control
AUC/Recirculated-air mode
You can respond to unpleasant 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, recirculated-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.
The recirculated-air mode should not be
used over an extended period of time;
otherwise, the air quality inside the car will dete-
riorate continuously.<
Via the button on the steering wheel
You can switch quickly between the recircu-
lated-air mode and the previous mode using a
button
on the steering wheel, refer to page11.
ALL program
Press the button.
The current temperature setting
on the driver's side is transferred to
the front passenger side.
If the temperature setting on the driver's side is
changed, the temperature on the front passen-
ger side is changed as well.
The program is switched off when the setting is
adjusted on the front passenger side or the but-
ton is pressed again.
Defrosting windows and removing
condensation
Press the button.
Quickly removes ice and conden-
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
Press the button.
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 window defroster.

Ventilation
1Use the thumbwheels to smoothly open
and close the air vents
2Use the lever to change the direction of the
airflow
3Thumbwheel for more or less cool air from
the vents 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.
Ventilation in the rear
1Use the thumbwheel to adjust the
temperature:
>Turn toward blue: colder
>Turn toward red: warmer
2Use the thumbwheel to smoothly open and
close the air vents
3Use the lever to change the direction of
the airflow
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.

Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns.<
Coolant consists of half water and half additive.
Not all commercially available additives are
suitable for your BMW. Ask your BMW center
for suitable additives.
Only use suitable additives; otherwise,
engine damage may result. Because
additives are harmful to your health, it is impor-
tant to follow the instructions on the contain-
ers.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking coolant level
1.Do not open the engine hood before the
engine has cooled down.
2.Turn the cap of the expansion tank a little
counterclockwise to allow any accumulated
pressure to escape, then continue turning
to open.
3.The coolant level is correct if it is between
the maximum and minimum marks in the
filler neck, refer also to the diagram next to
the filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level; do not overfill.
5.Turn the cap until there is an audible click.
6.Have the reason for the coolant loss elimi-
nated as soon as possible.
