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
over rapidly.
For more detailed information on the sys-
tem and how to make the best use of it,
read the instructions given in the following
pages.

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 other
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.
On some versions, the system is integrated
with an incipient misting sensor installed be-
hind the internal rearview mirror, which is
able to "monitor" a predefined area of the
windscreen inner surface which can auto-
matically act on the system to prevent or re-
duce 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
function.
