Air-conditioning main menu

Switching cooling with air-dehumidification on/off

Cooling is operational when the engine is running and cools according to the selected interior temperature. Cooling also dehumidifies the air inside the vehicle and thereby prevents the windows from misting up.

Risk of accident

If you deactivate the cooling function with air dehumidification, the vehicle will not be cooled in warm weather and the air will not be dehumidified. The windows could mist up more quickly. This may prevent you from observing the traffic conditions, thereby causing an accident.
Environmental note

The cooling system uses the refrigerant R134A. This refrigerant does not damage the earth's ozone layer.

Condensation may collect on the underside of the vehicle when the cooler is operating.
  

Open the air-conditioning main menu via the air-conditioning function bar.
  

Select and press .
 

A tick appears when the cooling function is deactivated.

Controlling the air conditioning centrally

You can use the Mono function to set all the air-conditioning zones in the vehicle to the same settings. If the Mono function is switched on and you adjust the air conditioning on the driver’s side, these changes will also be made in all the air-conditioning zones.

  

Open the air-conditioning main menu via the air-conditioning function bar.
  

Select Mono and press .
 

A tick appears when the function is selected.

The Mono function is automatically switched off if you:

  • change settings for the automatic air-conditioning system on the front-passenger side using COMAND.

  • operate one of the rocker switches for the rear-compartment air conditioning*.

Adjusting the footwell temperature

You can use the Footwell temperature function to set the temperature difference between the footwell and the rest of the vehicle interior.

This setting is quite effective in automatic mode, especially at low outside temperatures.

The greater the value you set, the higher the temperature in the footwell.

  

Open the air-conditioning main menu via the air-conditioning function bar.
  

Select Footwell temperature and press .
 

A scale appears.
  

To change the temperature difference: slide or turn .

You can select:

  • Focused (high blower setting)

  • Medium (standard setting)

  • Diffuse (low blower setting)

This setting is effective in automatic mode, especially at high outside temperatures.

If the vehicle has become very warm and the automatic air-conditioning system is cooling the interior, the blower settings are briefly suspended.
