Depending on the selected settings and outside
influences, the air is directed to the windshield,
side windows, upper body, and into the floor
area.
Air conditioning is switched on automatically with
the AUTO program.
Point the side vents toward the side windows.
At the same time, a condensation sensor con‐
trols the program so as to prevent window con‐
densation as much as possible.
The AUTO program is switched off automati‐
cally, when manual air distribution is set.
Intensity
With the AUTO program switched on, the inten‐
sity can be adjusted. This changes the automatic
control for the air mass.
Using the button:
Press the lower or upper side of the
button: decrease or increase intensity.

Climate control
Automatic recirculated-air
control AUC
Concept
The automatic recirculated-air control AUC rec‐
ognizes odors or pollutants in the outside air.
The outside air supply 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 recirculated-air mode, the air qual‐
ity in the car's interior deteriorates and window
fogging increases.

Recirculated-air mode
Concept
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 air flow within the vehicle.
