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 door
Operating from outside
>Via the remote control
>Via the door lock
>In cars with convenient access
*, via the
handles on the driver's and front passen-
ger's doors
The anti-theft system is also operated at the
same time. It prevents the doors from being
unlocked using the lock buttons or door han-
dles. 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 on the alarm system
*, refer
to page34.
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.<
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.
iDrive, for operating principle refer to page16.
1.Press the button.
This opens the start menu.

Automatic climate control
Comfortable interior climate
The AUTO program7 offers the ideal air distri-
bution and air flow rate for almost all conditions.
All you need to do is select an interior tempera-
ture which is comfortable 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.
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. Automatic air distribution adjustment
is deactivated.
You can switch the automatic air distribution
back on by pressing the AUTO button. This
automatically switches on the cooling function
as well.
Fine adjustments to manual air
distribution
You can set the rate of incoming airflow for
manual air distribution.
iDrive, for operating principle refer to page16.
1.Press the button.
This opens the start menu.
2.Move the controller to the left to open "Cli-
mate".
3.Select "Vent settings" and press the con-
troller.4.Select the desired field.
5.Turn the controller to set the air distribution.
1Airflow directed toward the windshield and
side windows
2Air to the upper body area
3Air to the footwell
Temperature
Set the desired temperatures indi-
vidually for the driver's and front
passenger's 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.
When you switch between different tem-
perature settings in quick succession, the
automatic climate control does not have
enough time to achieve the set temperature.<
You can achieve maximum heating power with
the highest setting, regardless of the outside
temperature.
The lowest setting effects continuous cooling.
Maximum cooling
At outside temperatures above
327/06 and when the engine is
running, you obtain a maximum
cooling effect as soon as possible.
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
them for maximum cooling.

AUTO program
The AUTO program adjusts the air
distribution to the windshield and
side windows, towards the upper
body area and into the footwell for you. The air
flow rate and your temperature specifications
will be adapted to outside influences as a result
of seasonal changes, e.g. sunlight or window
condensation.
The cooling is switched on automatically with
the AUTO program.
Intensity of the AUTO program
Press the AUTO button repeatedly to set the
intensity of the AUTO program. The current
setting is briefly displayed on the Control Dis-
play every time the button is pressed.
You can also set the intensity of the AUTO pro-
gram via iDrive.
iDrive, for operating principle refer to page16.
1.Press the button.
This opens the start menu.
2.Call up "Climate".
3.Select "Automatic programs" and press the
controller.
4.Select the desired field.
5.Press the controller to set the desired inten-
sity.
The selected intensity level of the auto-
matic program is switched on.
Convertible program
When the convertible top is down, the Convert-
ible program becomes available for selection. In
the Convertible program, the automatic climate
control is optimized for driving with the convert-ible top down. In addition, the air flow rate is
increased as vehicle speed increases.
When the Convertible program has been
selected, it is automatically activated every time
the convertible top is opened.
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 airflow. Press the right side
of the button to increase it. You can
reactivate the automatic mode for the air flow
rate with the AUTO button.
The air flow rate may be reduced or the blower
may be switched off entirely to save on 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 REST or rear window
defroster to reactivate the automatic climate
control.
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

Climate
100 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
continuously for lengthy periods, otherwise the
quality of the air inside the car will gradually
deteriorate.<
Via the button* on the steering wheel
You can use an individually programmable but-
ton on the steering wheel, refer to page53, to
select between the different modes.
Residual heat
The heat stored in the engine is
used to heat the passenger com-
partment, e.g. while 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 the engine has been
switched off
>While the engine is at operating tempera-
ture
>As long as battery voltage is sufficient
>At an outside temperature below 777/
256
The LED is lit when the function is on.
As of radio readiness, you can set the interior
temperature, air flow rate and air distribution.
Windows, defrosting and removing
condensation
Quickly removes ice and conden-
sation from the windshield and
front side windows.
Switch on the cooling function as well.
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 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.
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.
Ventilation
1Use the knurled wheels to smoothly open
and close the air vents
2Use the lever to change the direction of the
airflow
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.

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 suit-
able 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.
