Automatic recirculated-air control/
recirculated-air mode
Concept
The automatic recirculated-air control AUC
recognizes 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 pol‐
lutants in the outside air and controls the shut-
off automatically.
If the system is deactivated, outside air contin‐
uously flows into the car's interior.
With constant recirculated-air mode, the air
quality in the car's interior deteriorates and the
fogging of the windows increases.
Switching on/off
Press button repeatedly to select an
operating mode:
▷ LEDs off: outside air flows in continuously.
▷ Left LED on, automatic recirculated-air
control: a sensor detects pollutants in the
outside air and shuts off automatically.
▷ Right LED on, recirculated-air mode: the
supply of outside air into the vehicle is per‐
manently blocked.
Recirculated-air mode switches off automati‐
cally at low external temperatures after a cer‐
tain amount of time in order to avoid window
fogging.
