Maximum cooling effect
Principle
When drive-ready state is switched on, the sys‐
tem is set to lowest temperature, optimum air
flow and recirculated-air mode.
General
The function is available at an outside tempera‐
ture above approximately 0 ℃/32 ℉ and when
drive-ready state is switched on.
Switching on/off
Press the button.
The LED is illuminated when the sys‐
tem is switched on.
The air flows from the side nozzles for the upper
body area. Therefore open the side nozzles.
The air flow can be adapted when the pro‐
gramme is active.
AUTO programme
Principle
The AUTO programme cools, ventilates or heats
the interior automatically.
It does this by automatically regulating the air
flow, air distribution and temperature depending
on the interior temperature and the selected
temperature setting.
Switching on/off
Press the button.
The LED is illuminated when the AUTO
programme is switched on.

Climate
4. "Heating/ventilation"
5. "Automatic"
Depending on the selected temperature and ex‐
ternal influences, the air is directed towards the
windscreen, the side windows the upper body
and into the footwell.
The cooling function, see page 226, is switched
on automatically in the AUTO programme.
The AUTO programme is automatically switched
off when the air distribution is set manually.
Recirculated-air mode
Principle
If the air outside the vehicle has an unpleasant
odour or contains pollutants, the supply to the in‐
terior of the vehicle can be shut off. The air inside
the vehicle is then recirculated.
Operation
Press the button repeatedly to call up
an operating mode.
The LED is illuminated when the recirculated-air
mode is switched on. The outside air supply is
permanently shut off.
Via iDrive:
1. "CAR"
2. "Settings"
3. "Climate comfort"
4. "Air quality"
5. Select the desired setting:
▷ "Fresh air"
▷ "Air recirculation"
▷ "Automatic air recirculation"
The recirculated-air mode automatically switches
off after a given time depending on the ambient
conditions, to avoid condensation.
Continuous recirculated-air mode deteriorates
the air quality in the interior and condensation on
the windows increases.
