CAUTION  
					Air distribution control  
					We recommend not smoking in the vehicle when the recirculating air opera-  
					tion is switched on. The smoke sucked from inside the vehicle is deposited on  
					the evaporator of the air conditioner. This produces a permanent odour when  
					the air conditioning system is operating which can only be eliminated through  
					considerable effort and expense (replacement of compressor).  
					
					The recirculation mode prevents contaminated outside air getting into the In-  
					terior of the vehicle. In recirculated air mode air is sucked out of the interior of  
					the vehicle and then fed back into the interior.  
					To switch on, press the  button. The warning light below the button lights  
					up.

					To switch off, press the  button again. The warning light below the button

					If the air distribution control is set to position  when the recirculation modes  
					is switched on, the recirculated-air mode is switched off. By pressing the   
					button, the air recirculation also in this position can be switched on again.  
					When the cooling system ( button) is switched on and the temperature reg-  
					ulator is “turned” to the left, the recirculated-air mode is switched on.  
					Climatronic  
					
					The Climatronic can have a sensor that measures the air recirculation mode  
					and automatically turns on if there is an increased concentration of pollutants  
					in the incoming air.  
					The Air CareFunction reduces pollutant penetration contained in the outside  
					air into the vehicle.  
					When the function is activated, the air in the vehicle is circulated and cleaned  
					at the same time. The cleaning process is displayed by the zones displayed in  
					the Infotainment screen.  
					When the pollutant concentration decreases to the normal level, the recircula-  
					ted air mode is automatically switched off.  
					Automatic switch-on/switch-off of the air recirculation function can be set in  
					the Infotainment screen, by pressing the  button on the Climatronic and by  
					To switch on/off, press the  button on the Climatronic control panel, and  
					then tap on the function surface   → Active on the Infotainment  
					›
					then pressing the function surface  → Automatic air recirculation  
					.
					
					A shut-off of the air recirculation function takes place automatically by press-  
					ing the button, possibly depending on the moisture conditions in the vehi-  
					cle interior.  
					To ensure correct Air Care functioning, all doors and windows including the  
					panoramic sliding/tilting roof must be closed.  
					When opening a door or a window, the corresponding message is displayed in  
					the Infotainment screen.  
					WARNING  
					The air recirculation cannot be switched on for a longer period of time be-  
					cause there is no supply of fresh air from the outside. “Stale air” may result  
					in fatigue in the driver and occupants, reduce attention levels and also  
					cause the windows to mist up. As soon as the windows mist up, turn the air  
					recirculation mode off immediately - there is a risk of accident!
