WARNING
The climate control com-
pressor cannot work when
the outside temperature is less
than 2°C. Therefore, it is recom-
mended that the internal air recir-
culation function v is not used
when the outside temperature is
low, as the windows could mist

tem and how to make the best use of it,

The coolant used for the
climate control system is
R134a which meets cur-
rent regulations and does not harm
the environment in the event of ac-
cidental spillage.
Absolutely avoid the use of oth-
er fluids which are incompatible
with the system components.
GENERAL
The car is equipped with a two-zone cli-
mate control system, controlled by an elec-
tronic control unit which makes it possible
to separately adjust the air temperature on
the driver's side and on the passenger's side.
To obtain optimum temperature control in
the two areas of the passenger compart-
ment, the system has an outside sensor, a
passenger compartment sensor and a two-
zone sun ray sensor.
The system is integrated with an incipient
misting sensor installed behind the internal
rearview mirror, which is able to "monitor"
a predefined area of the windscreen inner
surface which can automatically act on the
system to prevent or reduce misting, through
a series of operations such as: opening air
recirculation, enabling compressor, air flow
to the windscreen, fan speed sufficient for
demisting; and, in case of heavy misting,
enabling the -
