3. Recirculation
Recirculation can be used to
shut out bad air, exhaust
fumes, etc. from the passen-
ger compartment. The air in
the passenger compart-
ment is recirculated, i.e. no
outside air is taken into the car when this
function is activated. If the air in the car recir-
culates for too long, there is a risk of misting
on the insides of the windows.
Timer
The timer function minimises the risk of icing,
misting and bad air if recirculation is
selected. See Personal preferences,
page 61, for how to activate/deactivate the
function.
3. Air quality system (option)
(same button as
recirculation)
The air quality system con-
sists of a multifilter and a
sensor. The filter separates
gases and particles to
reduce the levels of odours and pollution in
the passenger compartment. When the sen-
sor detects polluted outside air, the air
intakes are closed and the air in the passen-
ger compartment 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.
• The defroster functions for the front, side
and rear windows can be used to demist
the windows.
4. Defroster
Quickly removes misting
and ice from the windscreen
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 pas-
senger compartment:
• the air conditioning (AC) is automatically
switched on (can be switched off with the
AC 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.
