3. Recirculation
Recirculation can be used to
shut out bad air, exhaust
fumes, etc. from the
passenger compartment.
The air in the passenger
compartment is recirculated,
i.e. no outside air is taken into the car when
this function is activated. If the air in the car
recirculates for too long, there is a risk of
misting on the insides of the windows.
Timer
With the timer function activated (when the
recirculation function is selected) the risk of
ice, mist and bad air is reduced. To activate/
deactivate the function, see page 58.
NOTE! When Defroster (4) is selected, recir-
culation is always deactivated.
3. Air quality system
(same button as recircu-
lation)
The air quality system
consists of a multi-filter and
a sensor. The filter
separates gases and
particles to reduce the levels of odours and
pollution in the passenger compartment.
When the sensor detects polluted outside
air, the air intakes are closed and the air in the
passenger compartment is recirculated. A
green LED (A) lights in the button when the
air quality sensor is active.
Activating the air quality sensor:
– Press the AUTO (1) button to activate the
air quality sensor (normal setting).
Or:
– Switch between three functions by
pressing the recirculation button
repeatedly:

Keep in mind the following:
• As a rule, the air quality sensor should
always be engaged.
• Recirculation is limited in cold weather to
avoid misting.
• If the insides of the windows start misting
up, disengage the air quality sensor.
• The defroster function for the front, side
and rear windows can also be used to
demist the windows.

air conditioning gives maximum dehumidifi-
cation. The air is not recirculated.

incoming air is sufficiently
cooled and dehumidified.
