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.
The air volume is reduced to save battery
power. The display stays the same.
Air distribution, manual
You can route the air flowing out into the vehicle
interior via various programs, separately for the
driver's and passenger's side:
> Upper body region
> Upper body region and footwell
> Footwell
> Driver's side: windows and footwell
Selecting program
Press the button repeatedly until
the desired air distribution of the
respective program is shown on
the Control Display.
Switching cooling function on and off
The cooling function cools and
dehumidifies the incoming air
before also reheating it as
required, according to the temperature setting.
This function is only available when the engine
is running.
The cooling function helps to avoid condensa-
tion on the window surfaces or to quickly
remove them.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
The cooling function is also switched on with
the AUTO program.
Maximum cooling
Maximally cooled air is obtained as
quickly as possible at an outside
temperature above approx. 32
7/
0 6 and with the engine running.
At the lowest temperature, the automatic cli-
mate control switches into recirculated-air
mode. The maximum air volume flows out of the
vents for the upper body. Therefore, open these
vents for maximum cooling.
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.
Should the windows fog up in the recircu-
lated-air mode, press the AUTO button or
switch off the recirculated-air mode and
increase the air volume if necessary.
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
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.
1. Switch off the engine.
2. Turn to the right, refer to arrow.
The function can be switched on when the fol-
lowing conditions are met:
> up to 15 minutes after switching off the
engine
> with engine at operating temperature
> with sufficient battery voltage
