To prevent window fogging, recirculated-air
mode switches off automatically after a certain
amount of time, depending on the environmental
conditions.
With constant recirculated-air mode, the air qual‐
ity in the car's interior deteriorates and window
fogging increases.
If there is window condensation, switch off recir‐
culated-air mode or defog the windows.
