CONTROLS
Controlling the intensity of the air
flow
With the AUTO program switched on, the inten‐
sity can be adjusted. This changes the automatic
control for the air mass.
Press the left or right side of the button:
to decrease or increase intensity.
The selected intensity is shown on the display of
the automatic climate control.
Automatic recirculated-air
control
Principle
The automatic recirculated-air control recognizes
pollutants in the outside air. The outside air sup‐
ply is shut off and the interior air is recirculated.
General information
If the system is activated, a sensor detects pollu‐
tants in the outside air and controls the shut-off
automatically.
If the system is deactivated, outside air continu‐
ously flows into the car's interior.
With constant air recirculation mode, the air qual‐
ity in the car's interior deteriorates and window
fogging increases.
If there is window condensation, switch off recir‐
culated-air mode or defog the windows.

Air recirculation mode
Principle
You may react to unpleasant odors or pollutants
in the immediate environment by temporarily
suspending the supply of outside air. The system
then recirculates the interior air.
When recirculated-air mode is switched off, fresh
air is directed into the vehicle's interior.
Switch air recirculation on/off
Press the button.
The LED of the button is illuminated
when the air-recirculation mode is switched on.
To prevent window fogging, recirculated-air
mode switches off automatically after a certain
amount of time, depending on the environmental
conditions.
With constant air recirculation mode, the air qual‐
ity in the car's interior deteriorates and window
fogging increases.
If there is window condensation, switch off recir‐
culated-air mode or defog the windows.
Air flow, manual
Principle
The air flow for climate control can be adjusted
manually.
Adjusting the air flow manually
Press the left or right side of the button:
to decrease or increase air flow.
The selected air flow is shown on the display of
the automatic climate control.
The air flow of the automatic climate control may
be reduced automatically to save battery power.
