Rapid Window Demisting/Defrosting (Max-Def Function); Thermal Comfort Windscreen; Humidity Sensor - Alfa Romeo GIULIETTA Owner's Handbook Manual

With the compressor on and the engine
running, manual ventilation cannot be
lower than the minimum speed (only
one LED lit).
IMPORTANT With the compressor off,
air cannot be introduced to the
passenger compartment with
a temperature lower than the outside
temperature. Moreover, under certain
environmental conditions, windows
could mist up rapidly since the air is not
dehumidified.

❒ sets maximum air temperature (HI) in
both zones;
❒ sets fan speed according to the
engine coolant temperature;
❒ directs air flow to windscreen and

the heating filaments, to avoid damage
that might cause them to stop working
properly.
Thermal comfort
windscreen
(for versions/markets, where provided)
Some versions feature a thermal
comfort windscreen which, with the car
exposed to the sun, reduces the
temperature in the passenger
compartment relative to the outside
temperature, thus ensuring greater
comfort.

Humidity sensor

(for versions/markets, where provided)
The humidity sensor helps to prevent
the windows from misting up. For
full functionality, it is advisable to
activate the AUTO function (LED N on).
When the outside temperature is low,
the system could automatically turn the
compressor on and turn air recirculation
off for safer driving.
