Climate control compressor on/off
button B
Pressing button √ when the button led
is on, will deactivate compressor and turn
the button led off. Pressing the button
when the led is off will activate compres-
sor and turn the button led on. When
turning the compressor off, the system will
deactivate air recirculation to prevent win-
dow misting up.
In this event, although the system is able
to keep the required temperature, the
wording FULL will disappear from the
display. If the system is no longer able to
keep the required temperature, temper-
ature value will flash and the wording
AUTO will disappear from the display.
IMPORTANT With the climate control
compressor off, it is not possible to admit
air to the passenger compartment with a
temperature below the outside tempera-
ture; moreover, under certain environ-
mental conditions, windows could mist up
fastly since air is not dehumidified.
The switching off of the climate control
compressor remains in storage even when
the engine has been stopped.
To restore automatic control for switch-
ing on the climate control compressor,
press again button √ or press button AU-
TO.
With climate control compressor off if
outside temperature is higher than the set
one the system will not be able to keep
the required condition, the temperature
value will then start to flash on the display
for a few seconds and wording AUTO
will then go off.
With climate control compressor off, the
fan speed can be set to zero manually.
With compressor on and engine running,
the fan speed cannot be lower that one
bar on the display.

sor when climatic conditions are suit-
able;
❒ air recirculation off;
❒ maximum air temperature HI on both
areas;
❒ activates proper fan speed according to
engine coolant temperature to limit the
flow into the passenger compartment of
air not warm enough to demist the win-
dows;
❒ directs air flow to windscreen and front
side windows vents;
❒ turns heated rear window on.
IMPORTANT Fast demisting/defrosting

tion is on, the button led and the heated
rear window button led are on.

ing button or the air recirculation buttons
