Automatic recirculated-air control
AUC
The concept
The automatic recirculated air control AUC au‐
tomatically recognizes odors or pollutants in
the outside air. The outside air supply is then
automatically shut off, the interior air is recircu‐
lated.
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.
If there is window condensation,
switch off the recirculated-air mode
and press the button on the driver's side to uti‐
lize the condensation sensor. Make sure that
air can flow to the windshield.

Recirculated-air mode
The concept
You may respond to unpleasant odors or pollu‐
tants in the immediate environment by tempo‐
rarily suspending the supply of outside air. The
system then recirculates the air currently
within the vehicle.
Operating via button
Press button repeatedly to select an
operating mode:
▷ LED off: outside air flows in continuously.
▷ LED on: the supply of outside air is perma‐
nently shut off.
With constant recirculated-air mode, the air
quality in the car's interior deteriorates and the
fogging of the windows increases.
If there is window condensation,
switch off the recirculated-air mode
and press the button on the driver's side to uti‐
lize the condensation sensor. Make sure that
air can flow to the windshield.
