AUTOMATIC TWO-ZONE CLIMATE CONTROL SYSTEM (where provided)
GENERAL
The car is fitted with a two-zone climate control
system which makes it possible to separately adjust the
air temperature on the driver’s side and on the
passenger’s side. Temperature control is based on the
“equivalent temperature” logic, i.e.: the system
continuously works to keep constant the comfort
inside the passenger compartment and to compensate
any variation of the outside climate conditions,
including sunshine detected by a proper sensor
provided for the purpose.
The climate control system automatically controls and
adjusts the following parameters and functions:
❒air temperature at driver/front passenger vents;
❒air distribution at driver/front passenger vents;
❒fan speed (continuous air flow variation);❒compressor switching on (to cool/dehumidify air);
❒air recirculation.
All the above functions can be changed manually at any
time, i.e.: you can always modify one or more function
settings. In this event, the system will no longer
implement the automatic control of the functions
changed manually (except for safety reasons, e.g.: risk
of window misting).
Manual selections prevail over automatic ones and
remain in storage until the user decides to resume
automatic control, except when the system cuts in for
particular safety conditions.
The control of functions not changed manually remains
automatic.
The amount of air admitted to the passenger
compartment does not depend on the car speed, since
it is electronically controlled by the fan.
In any case, the temperature of the air admitted to the
passenger compartment is controlled automatically
(except when the system is off) according to the
temperatures set on the driver’s and front passenger’s
displays or under certain climatic conditions if the
compressor is off).

SWITCHING THE CLIMATE
CONTROL SYSTEM ON
The system can be started in different ways, but it is
advisable to press one of the AUTO buttons and then
to turn the knobs to set the temperatures required on
the display.
It is possible to personalise required temperatures
(driver and passenger) with a maximum difference of 7
°C.
This way the system will start working completely
automatically to reach the temperatures set as quickly
as possible. The system will adjust the air temperature,
flow and distribution and will control the air
recirculation function and the conditioner compressor
on/off.
During fully automatic operation, the only manual
settings required are the following:
❒MONO, to align the air temperature and
distribution set on the passenger’s side (front or
rear) with that on the driver’s side;
❒…, air recirculation, to keep it always on or off;
❒-, to speed up demisting/defrosting of
windscreen, front side windows, rear window and
door mirrors;
❒(, to demist/defrost the rear heated window and
the door mirrors.During completely automatic system operation, the
temperatures, air distribution and the fan speed set
can be changed at any time through the relevant
buttons or knobs: the system will automatically change
its settings to adjust to the new requirements.
During full automatic operation (FULL AUTO), any
change in air distribution and/or air flow and/or
compressor turning on and/or air recirculation will
obtain FULL disappearing. In this way functions will be
controlled manually until pressing the AUTO button
again. The fan speed is the same for all passenger
compartment areas.
With one or more functions engaged manually, the
adjustment of the temperature of the air admitted to
the passenger compartment continues to be
controlled automatically by the system, except with
the climate control compressor off. In fact, in this
condition, the air admitted to the passenger
compartment cannot have a lower temperature than
the outside air.

Turning the knobs
clockwise or
counterclockwise,
highers or lowers the temperature of the air required
respectively in the left zone (knob N) or right zone
(knob H) of the passenger compartment.
It is possible to personalise required temperatures
(driver and passenger) with a maximum difference of 7
°C.
The temperatures set are shown on the displays near
the relevant knobs.
Pressing button A (MONO) automatically aligns the
temperature on the front passenger’s side with that on
the driver’s side. It is therefore possible to set the
same temperature between the two zones simply
turning the knob on the driver’s side (N).
This function is provided to simplify temperature
adjustment of the whole passenger compartment when
only the driver is on board.
Separate operation of the set temperatures is
automatically restored by turning knobs (H) or
pressing button A (MONO) again when the button led
is on.Turning the knobs clockwise or counterclockwise until
they reach the extreme selections HI or LO, the
maximum heating or cooling functions are respectively
engaged:
❒HI function (highest heating power):
this is activated by turning the temperature knob
clockwise above the max. value (32 °C). It can be
activated independently from the driver’s or
passenger’s side or both (also selecting the MONO
function).
This function can be engaged when requiring to heat
the passenger compartment as quickly as possible,
exploiting the maximum potential of the system. This
function uses the maximum temperature of the
coolant fluid, while air distribution and fan speed are
controlled according to the system settings.
More particularly, max. fan speed will not be
immediately engaged if coolant is not hot enough; this
to prevent admitting air that is not warm enough to
the passenger compartment.
All manual settings are however possible with this
function on.

Air recirculation is controlled
according to the following operating
logics:
❒forced switching on (air recirculation
always on), indicated by the turning
on of the led on button (C) and
symbol íon the display;
❒forced switching off (air recirculation always off
with air inlet from the outside), indicated by the
turning off of the button led and êon the
display. AUTO buttons
(H-N)
(automatic
operation)
Pressing the AUTO
button (on driver and/or front passenger side) the
system automatically adjusts the amount and
distribution of the air admitted to the passenger
compartment, cancelling all the previous manual
adjustments.
This condition is indicated by the message FULL
AUTO on the front system display.
Manual operation of at least one automatic function
(air recirculation, air distribution, fan speed or climate
control compressor off) will cause FULL message
going off the display. This means that automatic
control is not complete (except temperature control
which is always automatic).
IMPORTANT Should the system (after manual
settings) be no longer able to guarantee the required
temperature set in the passenger compartment, the
set temperature value will start flashing to indicate this
condition, after one minute the AUTO message will
turn off.
To restore automatic system control after one or
more manual selections, press button AUTO.MONO button (A) (alignment of
set temperatures and air
distribution)
Pressing button MONO automatically
aligns the temperature on the front
passenger’s side with that on the driver’s side. It is
therefore possible to set the same temperature and air
distribution between the two zones simply turning the
knob on the driver’s side. This function is provided to
simplify temperature adjustment of the whole
passenger compartment when only the driver is on
board. Separate operation of the set temperatures and
air distribution is automatically restored by turning
knob (H) or pressing button MONO (A) again when
the button led is on.

the required temperature, the message FULL on the
display will go off. If the system is no longer able to
keep the required temperature, also the message
AUTO will turn off.
IMPORTANT Air at a temperature lower than that of
the outside air cannot be let into the passenger
compartment when the compressor is off.
Furthermore, in particular environmental conditions,
the windows could mist up fast because the air is no
longer dehumidified.Setting will be stored also when the engine is stopped.
Either press again button
√(in this case the system
operates as heater only) or AUTO to reset automatic
control of the compressor.
With compressor off, if the outside temperature is
higher than the set temperature, the system cannot
reach the required temperature. This will be signalled
by the flashing of set temperature value on the display
for a few seconds, then the message AUTO will go off.
When the compressor is off, it is possible to reset
manually the fan speed (no bar displayed).
When the compressor is on and the engine is running,
fan speed cannot be lower than the minimum (one bar
displayed).
