AUTOMATIC TWO-
ZONE CLIMATE
CONTROL SYSTEM
(where provided)
GENERAL INFORMATION
The two-zone automatic climate control
system distributes air in the passenger
compartment in two zones: driver’s and
passenger’s side. Temperature is con-
trolled on the basis of an “equivalent tem-
perature” principle; in other words, the
system continuously works to keep the
comfort level inside the car constant and
to compensate for possible variations of
external conditions, including sun radia-
tion detected by a specific sensor.
The automatically controlled parameters
and functions are:
❒air temperature at the vents on dri-
ver/front passenger side;
❒air at vents on driver/front passenger
side;
❒fan speed (continuous air flow varia-
tion);
❒compressor activation (to cool/dehu-
midify air);
❒air recirculation.All functions may be manually changed. In
order words, you may select one or more
functions and change the parameters as
required. Automatic control of the man-
ually changed functions will be suspended:
the system will change override your set-
tings only for safety-related reasons (e.g.
risk of misting up).
Manual selections will always have higher
priority over automatic settings and will
be stored until the user switches the sys-
tem back to automatic mode, except for
the cases in which the system will inter-
vene for particular, safety-related reasons.
You can adjust one function automatical-
ly and have the automatic system control
all the others.
The amount of air introduced into the pas-
senger compartment is independent from
speed of the car because the fan is con-
trolled by the electronic system.
The temperature of the air taken in is al-
ways controlled automatically depending
on the temperature set on the display (ex-
cept when the system is turned off or un-
der certain conditions when the com-
pressor is off. The following parameters and functions
can be manually set:
❒air temperature on driver/front pas-
senger side;
❒fan speed (continuous variation);
❒air distribution to five positions (dri-
ver/front passenger side);
❒compressor enablement;
❒one-zone/two-zone distribution pri-
ority;
❒fast demist/defrost function;
❒air recirculation;
❒heated rear window;
❒system off.

maximum coolant temperature while air
and fan speed distribution are managed
by the system according to conditions.
Specifically, if the heating fluid is not
warm enough, the fan will not start up at
the maximum speed immediately to limit
introducing excessively cool air into the
passenger compartment.
All manual settings will be allowed when
this function is on.
To switch the function off, simply turn
the temperature knob anticlockwise and
set the required temperature.
❒LOfunction (maximum cooling):
select by turning the temperature knob
anticlockwise beyond the minimum
value (16 °C). It can be operated from
either by the driver or by the front pas-
senger (by selecting the MONOfunc-
tion).
This function may be used to cool down
the passenger compartment as fast as
possible and exploit the system potential
to the maximum. The function activates
air recirculation and the climate control
compressor, air distribution and fan
speed are managed by the system
according to environmental conditions. All manual settings will be allowed when
this function is on.
To switch the function off, simply turn
the temperature knob clockwise and set
the required temperature.
Air distribution
buttons
(I-M)
Press these buttons to
manually set one of the
five possible air distribu-
tion patterns on the left
and on the right side of
the passenger compart-
ment:
▲air flow to the windscreen and front
side window vents to demist or de-
frost them;
˙air flow at central and side dash-
board vents to ventilate the chest
and the face during the hot season;
▼air flow to the front and rear foot
well vents. Thanks to the natural ten-
dency of hot air to spread upwards,
this distribution pattern allows to
warm the passenger compartment
up as quickly as possible, providing
an immediate feeling of warmth.
˙
▼Air flow between foot well vents
(hotter air) and central and side
dashboard vents (cooler air). This
distribution mode is particularly use-
ful in spring and autumn on a sunny
day.
▲
▼Air flow distributed between foot
well vents and windscreen and front
side window defrosting/demisting
vents. This allows an adequate
warming of the passenger compart-
ment and prevents the windows
from misting up.
The set distribution is shown by the cor-
responding LEDs on the selected buttons.
When the combined function is on, press
a button to activate the corresponding
functions along with the settings. If the
button corresponding to a previously ac-
tive button is pressed, the function is
turned off and the corresponding LED will
go out.
To restore automatic air distribution con-
trol after a manual adjustment, press but-
ton AUTO.
Air distribution is automatically aligned on
driver and passenger side when the driver
selects air distribution towards the wind-
screen. The passenger can select a differ-
ent distribution by pressing the corre-
sponding buttons afterwards.

the fan speed and
therefore the amount of air admitted
into the passenger compartment,
although keeping the required tempera-
ture set.
The fan speed is shown by the lit bars on
the display:
❒Max. fan speed = all bars lit;
❒min fan speed = one bar lit.
The fan can be cut off only if the climate
control compressor has been switched
off pressing button B.

The message FULL AUTOwill appear
on the front display in this condition.
By manually intervening on at least of the
functions automatically managed by the
system (air recirculation, fan speed or
compressor on/off), the word FULL will
disappear from the display indicating that
the system is no longer automatically con-
trolling all the functions (the temperature
will still be controlled automatically by the
system).
IMPORTANT Should the system (after
manual settings) be no longer able to guar-
antee the required temperature set in the
passenger compartment, the set tempera-
ture value will start flashing to indicate this
condition, after one minute the AUTO
message will turn off.To restore system automatic control at
any time, after one or more manual ad-
justments, press button AUTO.

settings)
Press MONOto auto-
matically align air temperature and distri-
bution settings in the front passenger area
to those of in the driver’s area and to
therefore set both zones by turning the
knob on driver’s side only. This function
is used to adjust the temperature in the
entire passenger compartment in pres-
ence of the driver only. To go back to sep-
arate air and temperature distribution in
the two zones of the passenger compart-
ment, simply turn the knobs H-fig. 62or
press MONO A-fig. 62when the LED
on the button is on.

Fast window
demisting/
defrosting button
(F)
Press this button: the cli-
mate control system will automatically
switch on all the functions required for fast
windscreen and front side window demist-
ing/defrosting, that is:
❒switches on the climate control com-
pressor when weather conditions are
suitable;
❒air recycle off;
❒maximum air temperature HIon
both areas;
❒sets proper fan speed according to
engine coolant temperature to limit
the flow of not sufficiently warm air
to demist the windows into the pas-
senger compartment;
❒directs the air flow to the windscreen
and front side windows vents;
❒heated rear window on.
IMPORTANT The fast demist/defrost
function will remain on for approximate-
ly 3 minutes, from when the engine
coolant reaches a temperature of 50°C
(petrol versions) or 35°C (Multijet ver-
sions).
When this function is on, the LED of the
corresponding button switches on and
that of the rear window demister. Themessage FULL AUTOgoes off on the
display.
You can only adjust the fan speed and
switch the rear window demister off
manually when this function is active.

The heater will go out automatically af-
ter a certain time or by pressing the but-
ton again. It will also go out when the en-
gine is stopped until it is started again.
IMPORTANT Do not apply stickers over
the electric filaments on the inside of the

Press Eto switch the cli-
mate control system off.
The display will go out
as a consequence.
The following climate control conditions
will be established when the system is off:
❒LEDs off;
❒set temperature not shown;
❒air recirculation on, passenger com-
partment isolated from the outside;
❒air conditioner compressor off;
❒fan off.
The rear window heater can be turned
on and off manually by pressing Gwhen
the system is off.
IMPORTANT The climate control sys-
tem control unit stores the settings
before the system is turned off and rep-
resents the same settings when it turned
back on by pressing any button (except
for the heated rear window). If the but-
ton of a function was not pressed before
turning off the system if will be turned
on; if the functions was on it will be kept
on.
