Activating/deactivating air-recirculation 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.
The indicator lamp in the
button
lights up.
In the event of high pollution
levels or at
high outside temperatures, airrecirculation
mode is automatically
activated. 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
goes
out.
Air-recirculation mode
deactivates automatically:
• after approximately five minutes if outside temperatures are less than about
41 °F (5 °C)
• after approximately five minutes if cooling with air dehumidification is
deactivated
• after approximately 30 minutes if outside temperatures are over about 41 °F
(5 °C)
