Description
The automatic dual zone climate control system regulates
the air temperatures in the passenger compartment in
two zones: driver side and passenger side.
The system maintains comfort inside the passenger com-
partment and compensates for possible variations in
external climate conditions.The climate control system can recognize extremely cold
(or extremely hot) conditions in the passenger compart-
ment and consequently provide optimal management of
the system’s capabilities.
NOTE:
The reference temperature is 71.6° F (22° C) for
optimal comfort management.
The automatically controlled parameters and functions
are:
• air temperature at the driver/front passenger side
vents;
• fan speed (continuous variation of the air flow);
• compressor engagement (for cooling/dehumidifying
the air);
• air recirculation.

UNDERSTANDING YOUR INSTRUMENT PANEL 195

All these functions can be adjusted manually by operat-
ing the system, selecting one or more functions and
modifying their parameters.
Automatic control of the functions will be suspended: the
system will only override the settings for safety reasons.
Manual selections always take priority over automatic
ones and are stored until the AUTO button is pressed or
the system itself intervenes for specific safety reasons.
The amount of air introduced into the passenger com-
partment is not affected by car speed; it is regulated by
the fan, which is controlled electronically.
The air temperature is always automatically controlled
according to the temperature set on the display (except
for when the system is off or in certain conditions when
the compressor is not running).The system allows the following to be set or adjusted
manually:
•
driver/passenger side air temperature;
• fan speed (continuous variation);
• air distribution to seven positions;
• compressor enablement;
• rapid defrosting/demisting function;
• air recirculation;
• heated rear window;
• system deactivation.

NOTE:The climate control system detects the passenger
compartment temperature using a mean radiant tem-
perature sensor located in the interior rear view mirror
and protected by a specific cover. Obstructing the field of
view of this sensor with any object could cause the
climate control system to operate with less than optimal
efficiency.
Switching On the Climate Control System
The climate control system can be switched on in differ-
ent ways: it is advisable to press the AUTO button and
turn the knobs to set the desired temperatures.
In this way the system operates completely automatically
to adjust the temperature, quantity and distribution of
the air introduced into the passenger compartment. It
also manages the air recirculation function and the acti-
vation of the air conditioning compressor. During automatic operation, you can change the set
temperatures, air distribution and fan speed at any time
by using the relevant buttons or knobs: the system will
automatically change the settings to adjust to the new
requirements.
During completely automatic operation (AUTO), varying
the air flow and/or distribution (which are not dis-
played) causes the AUTO function LED to disappear and
the system to operate in MANUAL mode (displaying
both the flow and distribution requested).
When the compressor is deactivated, the AUTO opera-
tion remains active only if the system can guarantee
in-car comfort. Otherwise, the system switches to
MANUAL mode (the set temperatures will flash on the
display). The fan speed is the same in all the zones of the
passenger compartment.

Adjusting The Air Temperature
Rotate the Driver Temperature Control, or the Passenger
Temperature Control, dial clockwise or anti clockwise, to
adjust the air temperature in the front left (Driver Tem-
perature Control) or right (Passenger Temperature Con-
trol) zone of the passenger compartment.
The set temperatures are shown on the displays.
Press the SYNC button to align the air temperature
between the two zones.
Turn the Passenger Temperature Control knob to return
to the separate management of air temperatures in the
two zones.
Turning the control knobs completely in one direction or
the other activates theHI(maximum heating) or LO
(maximum cooling) functions respectively. To deactivate these functions, turn the temperature knob
to the desired temperature.
Air Distribution Selection
By pressing the Mode Control buttons (Up/Down/Right
arrows), it is possible to set one of the seven possible air
distributions manually:
•
Up Arrow – Air flow to the windshield and front side
window diffusers to defrost them. Use Defrost mode
with maximum temperature settings for best wind-
shield and side window defrosting. When the defrost
mode is selected, the blower will automatically default
to medium-high.
• Right Arrow – Air flow at central and side dashboard
vents to ventilate the chest and the face during the hot
season.
198 UNDERSTANDING YOUR INSTRUMENT PANEL

•Down Arrow – Air flow to the front and rear footwell
diffusers. This air distribution setting heats the passen-
ger compartment most quickly, giving a prompt sen-
sation of warmth.
• Right/Down Arrows – Air flow distributed between
footwell diffusers (hotter air) and central and side
dashboard vents (cooler air). This distribution setting
is useful in spring and autumn on sunny days.
• Up/Down Arrows – Air flow distributed between
footwell diffusers and windshield and front side win-
dow defrosting diffusers. This distribution setting al-
lows the passenger compartment to be warmed effec-
tively and prevents the windows from misting.
• Up/Right Arrows – Air flow distribution between
windshield defrosting diffusers and side and central
dashboard vents. This allows air to be sent to the
windshield in conditions of strong sunlight. •
Up/Right/Down Arrows – Air flow distribution to all
diffusers on the car.
NOTE: Air always flows from the side dashboard diffus-
ers: it is, however, possible to interrupt the air flow by
operating the wheel located near the corresponding
vents.
In AUTO mode, the climate control system automatically
manages air distribution (the LEDs on the Mode Control
buttons are off ).
When set manually, the air distribution is indicated by
the LEDs on the selected buttons switching on.
In combined function mode, functions are enabled to-
gether with those already set when the relevant button is
pressed. If a button whose function is already active is
pressed, the operation is cancelled and the corresponding
LED switches off.

To restore automatic control of the air distribution after a
manual selection, press the AUTO button.
AUTO Button
When the AUTO button is pressed (LED on button lit) the
climate control system automatically adjusts the follow-
ing settings in the corresponding zones:
•quantity and distribution of the air introduced into the
passenger compartment
• climate control system compressor and
• air recirculation.
Cancelling all previous manual adjustments.
This is indicated by the LED on the AUTO button
switching on. If the AUTO button is pressed when the AUTO LED is
on, the system switches to completely manual mode; it
displays the current flow and distribution status, which
will no longer be managed automatically.
If a manual intervention is made on at least the air
distribution or on the fan speed, the LED switches off to
indicate that the system is no longer controlling all
functions automatically.
Deactivating the compressor results in the deactivation of
automatic operation only if the system is no longer able
to guarantee comfort conditions (which depend on the
set temperature).
NOTE:
Should the system no longer be able to guarantee
the required temperature set in various passenger com-
partment zones, the set temperature value will flash for a
few seconds on the display.

To restore automatic system control after one or more
manual adjustments, press the AUTO button.
SYNC Button
Press the SYNC button (LED on button lit) to align the
passenger side air temperature with that of the driver
side.
This function makes temperature regulation easier when
the driver is travelling alone.
Turn the Passenger Temperature Control knob to set the
passenger side temperature and return to separate air
temperature management.
Air Recirculation
The Air Recirculation is managed according to the fol-
lowing operating logics:
•forced activation (air recirculation always on): indi-
cated by the LED on the Recirculation Control button; •
forced deactivation (air recirculation always off, air
intake from the outside), signalled by the LED on the
Recirculation Control button switching off.
Forced activation/deactivation can be selected by press-
ing the Recirculation Control button.
When the On/Off button is pressed, the climate control
system automatically activates internal air recirculation
(LED on Recirculation Control button on).
It is still possible to activate outside air recirculation (LED
on the button off ) and vice versa, by pressing the
Recirculation Control button.
In automatic operation, recirculation is managed auto-
matically by the system according to outside environ-
mental conditions.

UNDERSTANDING YOUR INSTRUMENT PANEL 201

NOTE:
•The engagement of the recirculation system makes it
possible to reach the required heating/cooling condi-
tions faster. It is, however, inadvisable to use it on
rainy/cold days as it would considerably increase the
possibility of the windows misting up inside (espe-
cially if the climate control system is off ). When the
outside temperature is low, recirculation is forced off
(air drawn in from the outside) to prevent the win-
dows from misting up.
• It is inadvisable to use internal air recirculation when
the outside temperature is low, since the windows
could mist up rapidly.
Climate Control System Compressor
Press the A/C Control button to activate/deactivate the
compressor (activation is indicated by the LED on the
button switching on). The system remembers that the compressor has been
switched off, even after the engine has stopped.
When the compressor is switched off, the system deacti-
vates air recirculation to prevent the windows from
misting up. In this case, if the system is capable of
maintaining the required temperature, the AUTO LED
does not switch off.
The temperatures will flash seven times and the AUTO
LED will switch off if the required temperature cannot be
maintained.
To restore automatic control of compressor engagement,
press the A/C Control button again or press the AUTO
button.
With compressor off:
•
if the outside temperature is higher than the set one,
the climate control system will not be able to satisfy the
request.
