The air conditioning system or the respective refrigerant compressor can be switched off using the "A/C" button or "A/C" and residual heat ON/OFF button. If these buttons are not installed in an operating panel, the air conditioning or the respective refrigerant compressor can only be switched off via the menu in the head unit (A26/17).
The "SYNC" function is available independently from the operating unit via the Audio/COMAND control panel (A40/9) (even if the installed operating unit does not have a "SYNC button").
Location
The front climate control operating unit is located in the center console.
