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.
► Turn the SmartKey to position 2 in the
ignition lock.
► To activate: press the
button.

Air-recirculation mode is activated
automatically at high outside
temperatures. When air-recirculation mode
is activated automatically, the indicator
lamp in the
button is not lit.
Outside air is added after about 30 minutes.
► To switch off: press the
button.
The indicator lamp in the button

41 °F (5 °C)
• after approximately five minutes if
cooling with air dehumidification is
deactivated

temperatures are over about
41 °F (5 °C)
