BMW 3: AUTO program

Concept

The AUTO program cools, ventilates or heats the car's interior automatically.

The air distribution and temperature are controlled automatically depending on the temperature in the car's interior and the desired temperature setting including the selected intensity of the air flow.

Switching on/off

Press the button.

The LED is illuminated with the AUTO program switched on.

Via iDrive:

1. "CAR".

2. "Settings".

3. "Climate control".

4. "Heating/ventilation".

5. "Driver".

6. "Automatic".

Depending on the selected temperature, the intensity of the AUTO program, and outside influences, the air is directed to the windshield, side windows, upper body, and into the floor area.

The cooling function is switched on automatically with the AUTO program.

Point the side vents toward the side windows.

At the same time, a condensation sensor controls the program so as to prevent window condensation as much as possible.

The AUTO program is switched off automatically, when manual air distribution is set.

Intensity

With the AUTO program switched on, the intensity can be adjusted. This changes the automatic control for the air flow and air distribution.

Press the lower or upper side of the button: decrease or increase intensity.

Via iDrive:

1. "CAR".

2. "Settings".

3. "Climate control".

4. "Heating/ventilation".

5. "Driver".

6. "Level".

7. Set the desired intensity.

The air flow and air distribution are controlled automatically depending on the selected intensity.

The selected intensity is shown on the climate control display.

Automatic recirculated-air control AUC

Concept

The automatic recirculated-air control AUC recognizes 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 pollutants in the outside air and controls the shut-off automatically.

If the system is deactivated, outside air continuously flows into the car's interior.

With constant recirculated-air mode, the air quality 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 recirculated- air mode or defog the windows.
