ture sensor.
The brake servo works only when the engine
is running.
The heated windscreen 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.

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
●

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.
