Automatically controls the interior cabin temperature by
adjusting airflow distribution and amount. Performing
this function will cause the ATC to switch between
manual mode and automatic modes.
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.

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.

•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.

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.

•The fan speed can be reset manually.
With the compressor on and the engine running, manual
ventilation cannot be lower than the minimum speed
(only one LED lit).
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)
Press 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 maximum air temperature (HI) in both zones;
• 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 pressed, 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 tooutside 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
Press 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, press 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
Press 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 pressed
(except for the A/C Control button).
To restart the climate control system in fully automatic
mode press 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.
