If the outside air is contaminated then the air intake is closed in order to shut out hydrocarbons, nitrous oxides and ground-level ozone. The air is recirculated in the passenger compartment.
It is possible to activate/deactivate the function in the menu system MY CAR. For a description of the menu system, see MY CAR.
The air quality sensor must always be enabled to ensure the best air in the passenger compartment.
In a cold climate, automatic recirculation is limited so as to prevent misting.
