Electronic climate control, ECC*
3. Recirculation
The function is selected to
shut out bad air, exhaust
gases etc. from the passen-
ger compartment. The air in
the passenger compartment
is recirculated, i.e. no outside
03
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 mist-
ing on the insides of the windows.
Timer
The timer function reduces the risk of icing,
misting and bad air (if recirculation is selected).
To activate/deactivate the function see
page 82.
NOTE
When Defroster (4) is selected, recirculation
is always deactivated.
3. Air quality system*
Same button as recirculation.

96
Option/accessory, for more information, see Introduction.
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 light (A)
illuminates in the button when the air quality
sensor is active.
Activating the air quality sensor:
±
Press AUTO (1) to activate the air quality
sensor (normal setting).
Or:
±
Switch between three functions by press-
ing repeatedly the recirculation button.
•
Air quality sensor engaged – the light (A)
illuminates.
•
No recirculation engaged, provided it is not
required for cooling in hot weather – light
not illuminated.
•
Recirculation engaged – the light (M) illu-
minates.
Keep the following in mind:
•
As a rule, the air quality sensor should
always be engaged.
•
Recirculation is limited in cold weather to
avoid misting.
•
The defroster functions for the front, side
and rear windows can be used to demist
the windows.
4. Defroster
Used to quickly remove mist-
ing and ice from the wind-
screen and side windows. Air
flows to the windows at high
fan speed. The light in the
defroster button illuminates
when the function is active.
The following also takes place when the
defroster function is activated in order to pro-
vide maximum dehumidification in the passen-
ger compartment:
•
the air conditioning (AC) is automatically
switched on (can be switched off with the
AC button (6)
•
recirculation is automatically disengaged.
When the defroster is switched off the climate
control returns to the previous settings.
5. Air distribution
The airflow can be distributed
to the windows, dashboard
vents or floor by pressing the
air distribution buttons.
