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.

UNDERSTANDING YOUR INSTRUMENT PANEL 237

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 72° 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 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 pushed 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).
238 UNDERSTANDING YOUR INSTRUMENT PANEL

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 push 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.

•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
pushed. If a button whose function is already active is
pushed, the operation is cancelled and the corresponding
LED switches off. To restore automatic control of the air distribution after a
manual selection, push the AUTO button.
AUTO Button
When the AUTO button is pushed (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.

•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 push-
ing the Recirculation Control button.
When the On/Off button is pushed, the climate control
system automatically activates internal air recirculation
(LED on Recirculation Control button on).
In automatic operation, recirculation is managed auto-
matically by the system according to outside environ-
mental conditions. 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
Push the A/C Control button to activate/deactivate the
compressor (activation is indicated by the LED on the
button switching on).
244 UNDERSTANDING YOUR INSTRUMENT PANEL

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.
Pushing the A/C button will stop the AUTO MODE (the
AUTO LED will switch off). To restore automatic control
of compressor engagement, push the AUTO button
again.
NOTE:With the compressor off, air cannot be introduced
to the passenger compartment with a temperature lower
than the outside temperature. Moreover, under certain
environmental conditions, windows could mist rapidly
since the air is not dehumidified.
Rapid Window Demisting (MAX-DEF function)
Push the MAX-DEF button to activate (LED on button
on) the windshield and side window demisting function. The climate control system carries out the following
operations:
•
switches on the air conditioning compressor when
environmental conditions are suitable;
• switches air recirculation off;
• sets fan speed according to the engine coolant tem-
perature;
• directs air flow to windshield and front side window
diffusers;
• activates the heated rear window;
• activates the heated windshield (if equipped);
• displays the fan speed (Blower Control Indicator LED
lit).

NOTE:The Front Defrost Control (MAX-DEF) function
remains on for about three minutes from when the engine
coolant reaches the appropriate temperature.
When the function is activated, the LED on the AUTO
button switches off. With the function activated the only
possible manual adjustments are adjusting the fan speed
and turning the heated rear window off.
When the Recirculation Control, Rear Defrost Control , or
AUTO buttons are pushed, the climate control system
will deactivate the Front Defrost (MAX-DEF) function.
Selecting the footwell/windshield or only windshield
distribution activates the climate control system com-
pressor (LED on A/C button on) and the air recirculation
is set to outside air intake (LED on the recirculation
button off ). This logic guarantees optimum visibility at the windows.
It is, however, always possible to manage air recirculation
and the climate control system compressor manually.
Rear Window Defrosting
Push the Rear Defrost button to activate heated rear
window defrosting.
The effective activation of the function is indicated by the
rear defrost warning light on the instrument panel
switching ON.
This function switches OFF automatically after about 20
minutes or when the engine is turned OFF. It is not
switched on automatically the next time the engine is
started.
If equipped, push the rear defrost button to activate
defrosting of door mirrors and heated rear window.

NOTE:Do not affix stickers to the inside of the heated
rear window over the heating filaments, to avoid damage
that might cause them to stop working properly.
Switching Off The Climate Control System
Push the On/Off button.
With climate control system off:
• air recirculation is on, thus isolating the passenger
compartment from the outside;
• the compressor is off;
• the fan is off;
• the heated rear window can be activated / deacti-
vated. NOTE:
The climate control system control unit stores the
temperatures set before the system was switched off and
restores them when any button of the system is pushed
(except for the A/C Control button).
To restart the climate control system in fully automatic
mode push the AUTO button.
Additional Heater (If Equipped)
This allows the passenger compartment to be heated
more quickly in cold weather conditions.
The heater switches off automatically when the required
comfort conditions are achieved.
The additional heater activates automatically depending
on the environmental conditions and with engine started.
NOTE: The heater only operates if the outside tempera-
ture and engine coolant temperature are low. The heater
will not activate if the battery voltage is too low.
