Button For Rapid Window Demisting/ Defrosting (D) - Fiat Ducato Owner's Manual

IMPORTANT With the compressor off, it is not possible
to introduce air into the passenger compartment at a tem-
perature lower than he outside air. In certain weather
conditions, the windows could mist up rapidly due to the
effect of the non-dehumidified air.
The switching off of the compressor remains memorised
even when the engine has been stopped.
To restore automatic compressor control, press the √
button again (in this case, the system will only work as
a heater) or press the AUTO button.
With the compressor switched off, if the outside tem-
perature is higher than the one set, the system is not ca-
pable of satisfying this request and signals it by the digits
for the temperature setting flashing after which the word
AUTO goes out.
With the climate control compressor off, the fan speed
can be set to zero manually (no bar shown).
With the compressor enabled and the engine started, the
fan speed may be reduced to the minimum setting (only
one bar shown).
Button for rapid window demisting/
defrosting (D)
When this button is pressed, the climate con-
trol automatically activates all the functions
necessary to speed up the demising/
defrosting of the windscreen and the side
windows:
❒ the climate control compressor is turned on when
weather conditions are suitable;
❒ the air recirculation is turned off;
❒ the maximum air temperature for the HI air is set in
both areas;
❒ the fan speed is set according to engine coolant tem-
perature to limit the flow of not sufficiently warm air to
demist the windows;
❒ the air flow is directed to the windscreen and front side
windows vents;
❒ the heated rear winscreen is turned on.
IMPORTANT The rapid demisting/defrosting function for
the windows remains on for about 3 minutes from when
the engine coolant reaches the appropriate temperature
for the rapid demisting of the windows.
When this function is active, the LED in the correspond-
ing button and the one for the heated rear windscreen but-
ton switch on. The message FULL AUTO goes off on the
display.
You can only adjust the fan speed and switch the heated
rear windscreen off manually when this function is active.

simply press button B, or air recirculation button G, or the
compressor button F or the AUTO button A.
