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.
Switching on/off
Via iDrive:
1.
"CAR"
2. "Settings"
3. "Climate control"
4. "Air quality"
5. "Automatic"
If there is window condensation, switch off recir‐
culated-air mode or defog the windows, refer to
page 214.
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.
Operation
Press the button:
The LED is illuminated when recirculated-air
mode is switched on. The supply of outside air is
shut off.
When recirculated-air mode is switched off, fresh
air is directed into the vehicle's interior.
Via iDrive:
1. "CAR"
2. "Settings"
3. "Climate control"
4. "Air quality"
5. Select the desired setting:
▷ "Fresh air"
▷ "Air recirculation"
▷ "Auto-recirculate"
To prevent window fogging, recirculated-air
mode switches off automatically after a certain
amount of time, depending on the environmental
conditions.
With constant recirculated-air 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, refer to
page 214.
Adjusting the air flow manually
Concept
The air flow for climate control can be adjusted
manually.
General information
To adjust the air flow manually switch off AUTO
program first.
Operation
Press the lower or upper side of the
button: decrease or increase air flow.
The selected air flow is shown on the climate
control display.
