Operation
Windscreen heating*
Fig. 147
Windscreen humidity and tempera-
t
ur
e sensor.
The brake servo works only when the engine
is running.
The heat
ed windscr
een is comprised of a set
of heated wires placed between the layers of
the windscreen which, when electric current
is supplied to them, heat up and cause the
temperature of the glass to rise.
Its function is to assist the air-conditioning
system to prevent the windscreen from mist-
ing up or to demist it faster if it does mist up.
The system can be switched on manually or
automatically.
Manual activation
●
Press the button in the air conditioning
settings in the infotainment system.
The heated windscreen is switched off based
on the outside temperature and, in any case,
after approximately 8 minutes.
Automatic activation
The heated windscreen switches on automat-
ically when a window is at risk of misting up.
●
Open the air conditioning settings in the in-
fotainment system

page 157.
●
Switch the automatic heated windscreen
on or off.
The automatic heated windscreen is switch-
ed on, even when the air conditioning is
switched off.
Thermal windscreen using the defrost
function
If the defrost function is switched on and a
sensor detects that the windscreen could
mist up, the heated windscreen switches on.
When does the heated windscreen switch
off?
The heated windscreen switches off when
one of the following conditions is met:
●
Power consumption is too high.
●
The air conditioner fuse is faulty.
●
If the preset time has elapsed.
Troubleshooting
Cooling mode cannot be switched on or
operat
es in a limited way
The cooling mode works only with the engine
running and if the ambient temperature is
above +3 °C (+38 °F). When the engine is very
hot, the cooling mode is deactivated.
●
Switch on the fan.
●
Check the air conditioning fuse

The heating and fresh air system cannot
be switched on or operates in a limited
way
●
The heating and fresh air system and the
defrost function operate best when the en-
gine is hot.
●
If the fault continues, consult a specialised
workshop.
The windows are misted up
Windows mist up when they are cooler than
the ambient temperature and the air is very
damp. Cold air can absorb less moisture than
hot air, so the windows mist up more often in
cold weather.
