Air recirculation
This mode can be selected to temporarily reduce the
entry of annoying odors or dust into the vehicle’s
interior.
Outside air is not supplied to the car’s interior.
To select, press O button.
To cancel, press O button again.
The system will automatically switch from recirculated
air to fresh air:
• after approx. 5 minutes at outside temperatures
below approx. 40 °F (5°C),
• after approx. 30 minutes, at outside temperatures
above approx. 40 °F (5°C),
• after approx. 5 minutes, if button S is pressed.
Notes:
If the windows should fog up from the inside, switch
from recirculated air back to fresh air.
At high outside temperatures, the system automatically
engages the recirculated air mode thereby increasing
the cooling capacity performance, switching to partially
fresh air within 20 minutes.

heating the interior for a short while.
Air volume and distribution are controlled
automatically.

charge level is insufficient.
