Air recirculation mode prevents fumes or unpleasant smells from entering the vehicle.

Fig. 109 On the dash panel: Climatic controls

Air recirculation mode  fig. 109 prevents strong odours in the outside air from entering the vehicle interior, for example when passing through a tunnel or in queuing traffic.

With low outside temperatures, the air recirculation increases the effectiveness of the heating system by warming the air inside the passenger compartment rather than the air from outside.

With high ambient temperatures, the air recirculation increases the effectiveness of the air conditioning system by cooling the air inside the passenger compartment rather than the air from outside.

For reasons of safety, air recirculation is not possible when the control for air distribution is set to the windscreen setting .

WARNING

In air recirculation mode, no ambient air enters the vehicle interior. If the air conditioning system is switched off, the windows can quickly mist over.

Therefore, you should never leave the air recirculation mode switched on for longer periods, as this increases the risk of an accident.
