Air recirculation: automatic activation*
If the outside air is polluted by diesel and petrol emissions,
an air quality sensor in the vehicle will automatically switch
on the air recirculation.
Activating air recirculation mode
– Press the button ⇒ fig. 142.
Deactivating air recirculation mode
– Press the button again or
– Press the button or
– Press button .
The automatic air recirculation mode should normally be left switched on at
all times.
The system is ready to operate approx. 30 seconds after the engine ignition
key has been turned. During this initial period, fresh air is fed into the vehicle.
If the air purity sensor in the air conditioner detects a certain concentration
of fumes in the outside air, the control unit will either pass the incoming air
through the pollution filter or automatically switch on the air recirculation. If
there is a high concentration of pollution in the outside air, the air conditioner
automatically switches to air recirculation and the supply of air from the
outside is cut off. As soon as the level of pollution decreases, air is fed into
the vehicle from the outside again.
The automatic air recirculation operates for a maximum period of 12 minutes.
If the windows mist up when the automatic air recirculation is on, press the
button immediately.
The automatic air recirculation switches itself off under certain circumstances
(for instance if or is selected). In “ECON” and at temperatures lower
than approx. 8 °C below zero, the automatic air recirculation mode is limited
to 12 seconds.
Switching the temperature display from °C to °F and vice
versa
The temperature display can be switched from °C (degrees
Celsius) to °F (degrees Fahrenheit) and vice versa.
– Press and hold the button for air recirculation mode and
briefly press the plus button of the left-hand temperature
selector ⇒ page 164, fig. 141.
