CONTROLS
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 set. This changes the automatic con‐
trol for the air flow and air distribution.
Press the left or right side of the button:
decrease or increase intensity.
The selected intensity is shown on the display of
the automatic 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 the fog‐
ging of the windows increases.
Switching on/off
Via iDrive:
1. "My Vehicle"
2. "Vehicle settings"
3. "Climate functions"
4. If necessary, "Air quality"
5. "Automatic air recirculation"
If there is window condensation, switch off recir‐
culated-air mode or defog the windows, refer to
page 239.

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 button repeatedly to select an op‐
erating mode:
▷ LED off: outside air flows in continuously.
▷ LED on: the supply of outside air is perma‐
nently shut off.
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 the fog‐
ging of the windows increases.
If there is window condensation, switch off recir‐
culated-air mode or defog the windows, refer to
page 239.
Controlling the air flow manually
Concept
The air flow for climate control can be adjusted
manually.
General information
To manually adjust air flow switch off AUTO pro‐
gram first.
Operation
Press the left or right side of the button:
decrease or increase air flow.
The selected air flow is shown on the display of
the automatic climate control.
