The air conditioning system can be switched off using the "A/C" button. If this button is not installed on a control panel, the air conditioning system can only be switched off through the menu in the head unit (A26/17).
The "SYNC" function can also be selected through the head unit irrespective of the climate control operating unit (even if the installed operating unit does not have a "SYNC button").
Location
The climate control operating unit is located in the center console.
Task
The climate control operating unit has the following tasks:
