Rear
The operating concept is the same as for the
front heated seats.
Temperature distribution in front
The heat output can be distributed variously in
the seat cushion and the backrest.
Control Center, for principle details, refer to
page16.
Ignition key in position 2:
1.Select "Climate".
2.Select "Seat heater distribution" and press
the controller.
3.Move the controller to the left or right to
select "Driver" or "Passenger".
4.Turn the controller. The adjustment is
applied; the field can be changed.
Active seat ventilation*
The system progresses one step through the
control sequence each time you press the but-
ton.
To switch off: press the button longer.
The highest position with three LEDs is
used for rapid cooling, e.g. when the vehi-
cle has gotten heated up. After a short time, the
system is automatically switched down one
position in order to prevent excessive cooling.<
Active seat*
The seat cushion is actively varied by alter-
nately raising and lowering the right and left half
of the seat cushion. This reduces muscular ten-
sion and fatigue to help prevent lower back
pain.
Press the button to switch on; the LED lights
up.
If you switch off the active seat, it can take up
to 1 minute before the two halves of the seat
cushion have returned to their initial position.

A congenial climate
For almost all conditions, the AUTO program
offers the optimal air distribution and air vol-
ume. Select an interior temperature you find
pleasant.
The following section contains more detailed
information on the available setting options.
AUTO program
The AUTO program handles the
adjustment of air distribution to the
windshield and side windows, in
the direction of the upper body, and in the foot-
well, as well as the adjustment of the air volume.
It also adapts your instructions for the tempera-
ture to outside influences throughout the year.
The cooling is switched on automatically with
the AUTO program. At the same time, a con-
densation sensor controls the program in such
a way that window condensation is prevented
as much as possible.
Adjusting temperature
You can also set the desired tem-
perature on the driver's side and
the passenger side by turning the
knob.
When you start driving, the system ensures that
the selected temperature is achieved as quickly
as possible. It then maintains this temperature,
regardless of the season.
Defrosting windows and removing
condensation
This program quickly removes ice
and condensation from the wind-
shield and front side windows.
Air volume, manual
You can adjust the air volume by
turning. You can reactivate the
automatic mode for the air volume
with the AUTO button.
Switching cooling function on and off
manually
The cooling function cools and
dehumidifies the incoming air
before also reheating it as
required, according to the temperature setting.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
The cooling function is only available when the
engine is running and is switched on automati-
cally with the AUTO program.
Maximum cooling
This program quickly provides
maximum cooling.
The system switches to the recir-
culated-air mode and the air flows
at maximum air volume only from the air vent
outlets for the upper body area. For this reason
you should ensure that these vent outlets are
open before selecting this program.
AUC Automatic recirculated-air
control/Recirculated-air mode
You can respond to pollutants or
unpleasant odors in the immediate
environment by suspending the
supply of outside air. The system then recircu-
lates the air currently within the vehicle. During
AUC operation, a sensor detects pollutants in
the outside air and controls the shut-off auto-
matically.
By pressing the button repeatedly, you can
request three operating modes:
>LED off: outside air flows in continuously.
>Right LED on, AUC mode: the system
detects pollutants in the outside air and
shuts off the supply as needed.
>Left LED on, recirculated-air mode: the
supply of outside air is permanently shut off.
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 volume as
required.

A congenial climate
92 The recirculated-air mode should not be used
over an extended period of time, as the air qual-
ity inside the vehicle deteriorates continu-
ously.<
Residual heat mode
Press this button when the engine
is switched off, but warm.
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.
You can adjust the automatic climate control
settings in ignition key position 1.
Provided that the engine has warmed to its nor-
mal operating temperature and the battery is
charged, you can use this function for up to
15 minutes after switching off the ignition. The
LED in the button lights up to confirm compli-
ance with both of these conditions.
Switching off automatic climate control
The air volume, the heater and the
cooling function are all switched
off.
You can restart the automatic cli-
mate control by pressing any of its buttons
except the REST button.
Settings using Control Center
Ignition key:
>On vehicles with separate drives for audio
CDs and navigation DVDs, ignition key in
position 2
>In vehicles with one drive for audio CDs,
ignition key in position 1Control Center, for principle details, refer to
page16.
1.Press button.
This opens the start menu.
2.Move the controller to the left to open "Cli-
mate".

>Manual air distribution, separate for driver's
side and passenger side
>Adjusting temperature in upper body region
>Intensity of the AUTO program
The settings are stored for the remote control
currently in use.
Manual air distribution
You can preset your air distribution yourself and
also individually adjust the air temperature in
the upper body area.
1.Select "Vent settings" and press the con-
troller.
2.Move the controller to select the desired
field and turn the controller to adjust the air
distribution.
