Automatic recirculated air control/
recirculated air mode
You can respond to unpleasant
odors or pollutants in the immedi-
ate environment by temporarily
suspending the supply of outside air. The sys-
tem then recirculates the air currently within the
vehicle. In AUC mode, a sensor detects pollut-
ants in the outside air and controls the shut-off
automatically.
Press the button repeatedly to run through the
following control sequence:
>LEDs off: outside air flows into the vehicle
continuously.
>Left LED on, AUC mode: the system
detects pollutants in the outside air and
responds by blocking the supply of outside
air when required.
>Right LED on, recirculated-air mode: the
supply of outside air into the vehicle is con-
tinuously blocked.If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing air supply as
required. Make sure that air can flow to the
windshield, e.g. by pressing the AUTO button.
The recirculated-air mode should not be used
over a longer period of time, as the air quality
inside the vehicle deteriorates continuously.<
Automatic climate control, switching
on and off
The air volume, the heater, and the
air conditioner mode are all
switched off.
You can restart the automatic climate control by
pressing any of its buttons except the REST
button.
Temperature adjustment
You can turn to select the desired
temperatures for the driver's and
passenger sides. Your settings
appear on the status line of the
Control Display. The number
shown in the display provides a general indica-
tion of interior temperature.
The automatic climate control achieves this
temperature as quickly as possible at any time
of year, if necessary with the maximum cooling
or heating capacity, and then keeps it constant.
When switching between different tem-
perature settings in rapid succession, the
automatic climate control does not have suffi-
cient time to achieve the set temperature.<
Via iDrive
1.Open the start menu.
2.Open "Climate".
3.Turn the controller to select driver's side or
passenger side.
4.Turn the controller to select the field and
press the controller.
