Air-Recirculation Mode: Notes

In air-recirculation mode, the flow of outside air can be stopped to prevent pollution from entering the vehicle, e.g. in traffic congestion. Air inside the vehicle is continually recirculated.

To make sure that there is a sufficient supply of fresh air, air-recirculation mode is only available for a limited time (30 minutes air recirculation -> 30 seconds partial fresh air -> 30 minutes air recirculation -> etc.)
