3. Recirculation
Recirculation can be used
to shut out bad air, exhaust
fumes, etc. from the pas-
senger compartment. The
air in the passenger com-
partment 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 win-
dows.
Timer
The timer function minimises the risk of icing,
misting and bad air if recirculation is select-
ed. See Personal preferences, page 62, for
how to activate/deactivate the function.
3. Air quality system (option)
(same button as recircula-
tion)
The air quality system con-
sists of a multifilter and a
sensor. The filter separates
gases and particles to re-
duce 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 com-
partment is recirculated. A green light (A) in
the button illuminates 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 LED (A)
illuminates.
• No recirculation engaged, provided it is
not required for cooling in hot weather –
LED not illuminated.
• Recirculation engaged – the LED (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.
• 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.
4. Defroster
Quickly removes misting
and ice from the wind-
screen and side windows.
Air flows to the windows at
high fan speed. The light in
the defroster button lights
when the function is active.
The following also takes place when the de-
froster function is activated in order to pro-
vide maximum dehumidification in the pas-
senger compartment:
• the air conditioning (A/C) is automatically
switched on (can be switched off with the
A/C button (5)
• recirculation is automatically disengaged.
When the defroster is switched off the cli-
mate control returns to the previous settings.
NOTE
If the knob is turned anticlockwise and the
fan indication on the display goes out, the
fan and the air conditioning are switched
off. The display shows the fan symbol and
OFF .
NOTE
When Defroster (4) is selected, recirculation
is always deactivated.
