When recirculation is engaged the orange lamp in the button illuminates.
If the air in the car is recirculated for too long then there is a risk of misting on the insides of the windows.
With the timer function activated the system will exit manually activated recirculation mode according to a time that depends on the outside temperature. This reduces the risk of ice, misting and bad air.
It is possible to activate/deactivate the function in the menu system MY CAR. For a description of the menu system, see MY CAR.
When max. defroster is selected, recirculation is always deactivated.
