side windows, upper body, and into the floor
area.
Point the side air vents toward the side windows.
The cooling function is switched on with the
AUTO program.
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.

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.
