Flow of air towards the centre up-
per vent, centre and side dashboard out-
lets and rear outlets.
If the system was in the FULL AUTO
mode, pressing the
passes to the simple automatism condi-
tion: i.e. the system chooses the fan
speed and mixing to obtain the equiva-
lent temperature required, but will not
change the distribution selected manually.
Pressing the recirculation button
, the system automatically reac-
tivates the compressor if it was deactivat-
ed manually; to maintain recirculation
with the compressor of, it is necessary to
press the button to deacti-
vate the compressor.
IMPORTANT In this condition (recir-
culation on and compressor off), remem-
ber that the windows may steam up very
quickly.
Pressing the button the climate
control automatically activates the func-
tions required to quicken demisting/de-
frosting of the windscreen and side win-
dows. Rearscreen heating and door mirror
heating are also automatically engaged
(for a determinate length of time).
Pressing the
rearscreen heating and door mirror heat-
ing for a determinate length of time.
Manually setting one of the climate con-
button
trol functions, the others continue to be
controlled automatically; in particular the
air temperature is always controlled auto-
matically to reach the required "equiva-
lent temperature" in the passenger com-
partment.
IMPORTANT When working in the
FULL AUTO condition, the system can
automatically engage recirculation or de-
activate the compressor to cool/heat the
passenger compartment faster or
demist/defrost the windscreen and side
windows.
IMPORTANT When the engine is
button engages
turned off the system memorises the cli-
mate control operating condition, which
will be automatically resumed when the
engine is started again.
ACTIVATED CARBON
DUST/POLLEN AIR FILTER
The filter has the specific capability to
combine the mechanical air filtering func-
tion with an electrostatic effect so that
the outside air admitted to the passenger
compartment is purified and free of parti-
cles such as dust, pollen etc.
In addition to the above-mentioned
function there is also an effective reduc-
tion of the concentration of pollutants ow-
ing to a layer of activated carbons on the
lower surface of the filter.
The filtering action takes place when air
is admitted from outside (recirculation
off) and when the air is recirculated (re-
circulation on).
