Preventive demisting procedure
In cases of heavy damp and/or rain
and/or big differences in temperature be-
tween inside the car and outside, it is ad-
visable to proceed as follows to demist the
windows:
– turn off inside air re-circulation (if on)
– turn knob (1) as far as it will go clock-
wise
– turn knob (4) clockwise to an inter-
mediate speed
– turn knob (7) to
Q
or
ZQ
if the win-
dows do not mist up.
Climate control system is very useful to
speed up demisting. Set controls to demist-
ing function as described previously and
switch the climate control system on by
pressing button (2)
√
REARSCREEN AND WING
MIRROR (where applicable)
DEMISTING / DEFROSTINGPress button (6)
(
) to demist /defrost
the rearscreen and wing mirrors (where ap-
plicable).
When this function is on the relevant but-
ton led will come on.
To turn this function off, press the button
again, the button led will go off.
WARNINGDo not apply stickers on the
inside of the rearscreen over the heating fil-
aments to avoid damaging it.
FAN SPEED ADJUSTMENTTo ventilate the passenger's compartment
properly, proceed as follows:
– open completely the central and side
vents;
– turn knob (4) to the required speed;
– turn knob (7) to

SWITCHING THE INSIDE AIR
RE-CIRCULATION FUNCTION
ONPress button (3)
v
to turn the inside air
re-circulation function on.
When this function is on the relevant but-
ton led will come on.
It is advisable to turn on the inside air re-
circulation function in queues or tunnels to
avoid admitting polluted air from outside.
The prolonged use of this function should
however be avoided, especially with several
persons on board, to avoid the possibility of
the windows misting inside.WARNINGThe inside air re-circulation
function makes it possible to reach the re-
quired "heating" or "cooling" conditions
faster.
It is however inadvisable to use it on
rainy/cold days as it would considerably in-
crease the possibility of the windows mist-
ing inside, especially if the climate control
system is off.
CLIMATE CONTROL (COOLING) Proceed as follows:
– turn knob (1) as far as it will go coun-
terclockwise (blue led next to TEMPlit);
– turn knob (4) to the required speed;
– turn knob (7) to
E;
-– press buttons (2) √
and (3)
v
the
relevant leds will go on.

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.fig. 100

GENERALThe 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
MAX
-DEF
function.
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.
WARNING

The air quality control is also entrusted
to a combined particle and activated carbon
filter.
The climate control system automatically
controls and adjusts the following parame-
ters and functions:
– temperature of the air admitted to the
passenger compartment (for the driver’s and
passenger’s side separately)
– fan speed
– air distribution
– inside air recirculation on/off
– climate control compressor on/off en-
able.The settings of the following functions can
be modified manually:
– fan speed
– air distribution
– inside air recirculation on/off
– climate control compressor on/off en-
able
– window defrosting/demisting.
The control of the functions that have not
been modified manually will always be au-
tomatic and, in any case, the temperature
of the air flowing into the passenger com-
partment is controlled automatically de-
pending on the temperatures set on the dri-
ver’s and passenger’s displays.WARNINGManual selections prevail
over automatic ones and remain in storage
until the user decides to resume automatic
control. The settings selected manually are
stored when the engine is switched off and
resumed the next time the engine is started.

AIR DISTRIBUTION SELECTION
BUTTON
(fig. 108)
By pressing button MODE(8) repeat-
edly, you can manually choose one of the
five possible modes for air distribution:
E
Flow of air to the dashboard centre
and side outlets and rear outlets.
ZE
Splitting of the air flow between the
vents to the lower part of the pas-
senger compartment (warmest air)
and the dashboard centre and side
outlets and the rear outlet (coolest
air). This air flow distribution is par-
ticularly useful in spring and autumn,
when the sun is shining.
Z
Air flow towards the front and rear
lower part of the passenger compart-
ment. Due to the natural tendency of
heat to spread upwards, this type of
distribution allows heating of the pas-
senger compartment in the shortest
time, also giving a prompt feeling of
warmth to the coldest parts of the
body.
Q
Splitting of the air flow between the
windscreen and side window defrost-
ing/demisting vents and the lower
part of the passenger compartment.
This type of air distribution allows sat-
isfactory heating of the passenger
compartment while preventing pos-
sible misting of the windows.
Q
Air flow to the windscreen and front
side window vents to demist or de-
frost them.
To resume automatic air distribution con-
trol after a manual selection, press button
(14) AUTO
.

When the climate control compressor is off,
it is not possible to admit air to the pas-
senger compartment with a temperature be-
low the outside temperature; in this case,
the value flashes on the display concerning
the temperature that cannot be reached
and the left led on button (14

Operation of the climate
control compressor is nec-
essary for cooling and dehumidify-
ing the air; it is advisable to keep
this function always on, to prevent
window misting problems.
WARNING

GETTING TO KNOW YOUR CAR

With the outside temper-
ature below 2°C the cli-
mate control compressor is unable
to work. It is therefore inadvisable
to use the inside air recirculation
function v
with low outside tem-
perature as windows may mist
over quickly.WARNING
The inside air recirculation
function makes it possible
to reach the required “heating” or
“cooling” conditions faster. It is
however inadvisable to use it on
rainy/cold days as it would con-
siderably increase the possibility of
the windows misting inside, espe-
cially if the climate control system
is off.
WARNING
It is advisable to turn on the
inside air recirculation sys-
tem in queues or tunnels to avoid
admitting polluted air from outside.
The prolonged use of this function
should however be avoided, espe-
cially with several persons on
board, to avoid the possibility of the
windows misting inside.
WARNING
In certain weather condi-
tions (e.g. outside temper-
ature around 0°C) and with auto-
matic air recirculation control on,
mist may form on the windows. In
this case press the inside air re-
circulation button (7)
v
, to
switch off recirculation (leds on
button off) and if necessary in-
crease the flow of air to the wind-
screen.
