Button For Fast Windscreen Demisting/Defrosting - Lancia Thesis Owner's Handbook Manual

The air let into the passenger com-
partment cannot be cooled when the
compressor is off. Consequently:
– if the outside temperature is
lower than the set temperature, the
system works normally and can
reach and maintain the set tempera-
ture also when the compressor is off;
– if the outside temperature is
higher than the set temperature, the
system cannot reach the required
temperature. This will be signalled
by flashing the external temperature
value on the display.
When the compressor is off, it is
possible to reset manually the fan
speed; on the contrary, when the
compressor is on and the engine is
running, manual ventilation cannot
be lower than the bar indicated on
the display.

Press this button: the climate con-
trol system will automatically switch
on all the functions required for fast
windscreen and side window demist-
ing/defrosting, that is:
– climate control system compres-
sor on;
– air recirculation off (if on);
– maximum air temperature (HI)
on both displays;
– fan speed according to engine
coolant temperature in order to limit
letting cold air into the passenger
compartment for demisting the win-
dows;
– air flow directed to the wind-
screen and front side window vents;
– heated rear window, external
rearview mirror and windscreen noz-
zle resistances on.
The fast windscreen demisting/
defrosting function stays on for
approx. 3 minutes after the engine
coolant temperature exceeds 50 °C
(petrol versions) or 35 °C (diesel
versions).
When the fast demisting/defrosting
function is on, the led on the related
button and that on the heated rear
window button are lighted, while
both leds on the air recirculation
button and that on button √ turn
off. Message FULL AUTO on the
display will turn off.
Only the fan speed can be adjusted
and the heated rear window can be
switched off when the fast demist-
ing/defrosting function is on.
Press the fast demisting/defrosting
button again or air recirculation
button or compressor off button to
switch the fast demisting/defrosting
function off and reset the previous
system operation conditions as well
as the last set function.
