Activating/deactivating airrecirculation mode
You can deactivate the flow of fresh air if unpleasant odors are entering the vehicle from outside. The air already inside the vehicle will then be recirculated.
The operation of air-recirculation mode is the same for all control panels.
WARNING
Fogged windows impair visibility,
endangering you and others. If the windows
begin to fog on the inside, switching off the
air recirculation mode immediately should
clear interior window fogging. If interior
window fogging persists, make sure the air
conditioning is activated, or press the
button.

In the event of high pollution levels19 or at high outside temperatures, airrecirculation mode is automatically activated. When air-recirculation mode is activated automatically, the indicator lamp above the button does not light up.
Outside air is added after about 30 minutes.
•► To switch off: press the button.
The indicator lamp above the button goes out.

- after approximately 30 minutes if outside temperatures are over about 41 °F (5 °C)
