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 approximately 5 minutes at outside temperatures below approximately 40°F (5°C), • after approximately 30 minutes, at outside temperatures above approximately 40°F (5°C), • after approximately 5 minutes, if button S is pressed. 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.
