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 of 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.

Automatic climate control
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.
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 footwellTemperature
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.

Climate

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.
1.Press the button.
This opens the start menu.
2.Move the controller to the left to call up "Cli-
mate".
3.Select "Automatic programs" and press the
controller.4.Select the desired intensity and press the
controller.
The selected intensity level of the auto-
matic program is switched on.
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
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
