The cooling system uses
coolant “R134a” refriger-
ating fluid that meets cur-
rent regulations and does not
pollute the environment if it acci-
dentally leaks. Under no circum-
stances should other fluids be
used which are incompatible
with the system components. BACK CONTROL PANEL

HOW TO USE THE CLIMATE
CONTROL SYSTEM
The system can be switched on in
various ways. We recommend start-
ing by pressing the AUTObutton
and setting the required tempera-
tures on the display.
Since the system controls three
areas of the passenger compartment,
the driver and the front/back pas-
sengers can select different tempera-
ture values, with a maximum differ-
ence accepted by the system of 7 °
C.
In this way, the system will start
working fully automatically to reach
the required temperature as soon as
possible. It will maintain the tem-
perature by adjusting the amount
and distribution pattern of the air let
into the passenger compartment and
manage the recirculation function
and the climate control system com-
pressor.When the system is working auto-
matically, the only possible manual
functions are:
–MONO, to align air temperature
and distribution on the passenger
side or in the back-seat passengers’
area with that on the driver side;
–REAR, to activate the back con-
trol panel;
–√, to switch off the compressor:
in these conditions the system works
only as a heater;
– air recirculation, to keep recircu-
lation always turned on or off;
–-, for faster defrosting/demist-
ing the front windows, rear window,
external rearview mirrors and wind-
screen wiper nozzles;
–(, for defrosting/demisting the
heated rear window and external
rearview mirrors.The temperature, air distribution
and fan speed settings can be
changed at any time during auto-
matic system operation. The system
will automatically adjust to the new
request. When the system is fully
working in automatic mode (FULL
AUTO), if air distribution and/or
flow is changed, definition FULL
disappears. In this way functions
pass from the automatic mode to the
manual mode, until button AUTOis
pressed again. There is only one fan
speed for all the passenger compart-
ment areas and it can be changed
also by operating back controls,
when activated.
With one or more functions manu-
ally on, the air temperature let into
the passenger compartment is auto-
matically managed by the system
unless the climate control compres-
sor is off. In this condition, in fact,
the air inlet into the passenger com-
partment cannot have a lower tem-
perature than that of the external
air.

152
CONTROLS
Knobs for adjusting air tempera-
ture (2, 8 fig. 121 - 1 fig. 122)
Turn the knobs towards the right
or towards the left to raise or lower
the air temperature required respec-
tively in the front left-hand area
(knob2 fig. 121) and in the front
right-hand area (knob 8 fig. 121) or
back area (knob 1 fig. 122) of the
passenger compartment.
Since the system controls three
areas of the passenger compartment,
the driver and the front/back-seat
passengers can select different tem-
perature values with a maximum
difference accepted by the system of
7°
C.
Temperature control in the front
passenger area and in the back pas-
senger area is alternated; when the
button led REARis off, control of
front passenger side is on, but when
buttonREARis pressed (button led
on) the back control panel is activat-
ed.The set temperatures are shown on
the displays set near the respective
knobs.
Press button 16(MONO - fig. 121)
to automatically align the
(front/back) passenger temperature
to the temperature on driver’s side.
Consequently the temperature in the
two areas can be set simply by turn-
ing the knob on the driver side 2
(fig. 121). This function is provided
to facilitate adjusting the temperature
in the passenger compartment when
only the driver is present. The sepa-
rate operation of the set temperatures
and air distribution is automatically
reset when knobs 8 (fig. 121) or1
(fig. 122) are turned or button 16
(MONO - fig. 121) is pressed again,
when the button led is turned on.
Turn the knobs fully to the right or
to the left to the end positions HIor
LO, to obtain maximum heating or
cooling, respectively:–HIfunction (maximum heating):
this is switched on by turning the
temperature knob to the right
beyond the maximum value (32 °C).
It can be independently switched on
from driver’s side or from
(front/back) passenger’s side or
from both sides (also by selecting the
MONOfunction).
This function can be switched on to
speed up heating in the passenger
compartment by exploiting the sys-
tem potential to the maximum. The
function employs the maximum
coolant temperature while the air
distribution and fan speed are set by
the system according to environ-
mental conditions. In particular, if
the coolant temperature is not suffi-
cient, the function does not switch
the fan on at top speed to limit let-
ting into air which is not adequately
warm.
All the manually settings can be
adjusted when the function is on.

153
To switch this function off, turn
the temperature knob to the left and
set the required temperature.
–LOfunction (maximum cooling):
it is activated by turning the temper-
ature knob to the left beyond the
minimum value (16 °C). It can be
independently switched on from dri-
ver’s side or from (front/back) pas-
senger’s side or from both sides (also
by selecting the MONOfunction).
This function can be switched on to
speed up cooling the passenger com-
partment by exploiting the system
potential to the maximum. This
function cuts out the heater and
switches the air recirculation and the
climate control compressor on. The
air distribution and the fan speed
are selected according to the envi-
ronmental conditions. All the manu-
ally settings can be adjusted when
the function is on. To switch this
function off, turn the temperature
knob to the right and set the
required temperature.Buttons for adjusting front air
distribution (10, 18 fig. 121)
Press these buttons to manually
select one of the seven possible air
distribution patterns in the front
passenger compartment (right and
left side):
AAir flow to windscreen and front
side window vents for defrosting/
demisting the windows.
FDAir flow to central and side
dashboard vents and the rear vents.
IMPORTANTOn versions equipped
with solar cell operated sunroof
(where provided), to check opera-
tion at first speed of climate control
system fan when the car is parked,
disengage air vents and set air distri-
bution from central dashboard vents
only before leaving the car.
SAir flow to the front and rear
footwells. The air distribution pat-
tern, due to the natural tendency of
heat to move upwards, allows to
heat the passenger compartment up
as fast as possible. Furthermore, it
offers a prompt feeling of warmth to
the coolest parts of the body.Air flow shared between
footwell vents (warmer air)
and central and side dashboard
vents and the rear vents (cooler air).
This air distribution pattern is par-
ticularly useful in middle seasons
(spring and autumn) when it is
sunny.
Air flow shared between the
footwell vents and the windscreen
and front side window
defrosting/demisting vents. This air
distribution pattern ensures a good
heating of the passenger compart-
ment and prevents possible misting
up.
Air flow distribution between
central and side dashboard
vents, rear vents and windscreen
and front side window vents.
Air flow distribution
between all passenger com-
partment vents.

when leds relevant to the selected
button are lit, which will be turned
off in case of fully automatic opera-
tion (FULL AUTO).F

When a combined function is set, if
a button is pressed the main func-
tion of the button pressed is activat-
ed, together with those already set. If
the button corresponding to a func-
tion which is already on is pressed,
such function will be cancelled (the
related led turns off).
Press the AUTObutton to restore
air distribution control after a man-
ual setting.
When the driver selects the air dis-
tribution to the windscreen, also the
passenger side air flow is automati-
cally directed to the windscreen.
Anyway, the passenger can select
another air distribution pattern, by
pressing the related buttons.Buttons for adjusting rear air
distribution (6, 9 fig. 122)
When the back control panel is
activated, it is possible to set one of
the three air distribution patterns for
the passenger compartment back
area by pressing the related buttons:
DAir flow to back central vents.
SAir flow to rear footwells. This air
distribution pattern, due to the nat-
ural tendency of heat to move
upwards, offers a prompt feeling of
warmth to the coolest parts of the
body.

Buttons for adjusting fan speed
(13, 14 fig. 121 – 7, 8 fig. 122)
Press respectively front control
buttons13or14(fig. 121) and back
control buttons 8or7(fig. 122) to
increase or decrease the fan speed so
to adjust the amount of air let into
the passenger compartment while
keeping the required temperature
constant.
The fan speed is indicated by the
bars which light up on the front dis-
play5(fig. 121) and rear display 3
(fig. 122), when the back control
panel is active. Repeatedly press
button or keep pressed 13(fig. 121)
or8(fig. 122) to switch the fan on
at top speed (all bars on).
Repeatedly press or keep pressed
button14(fig. 121) or 7(fig. 122)
to switch the fan on at minimum
speed (one bar on).When the fan minimum speed is
set up (one bar on), by keeping
pressed for at least two seconds but-
ton14(fig. 121) or 7(fig. 122), the
climate control system is deactivated
and all the fan bars on the display
turn off; OFFmessage is displayed.
The fan speed can be adjusted
manually through both the front
control panel and the rear control
panel, but it is the same one for the
whole passenger compartment.
IMPORTANTPress the AUTO
button to restore air distribution
control after a manual setting.AUTO buttons
(automatic operation)
(1, 9 fig. 121 - 5 fig. 122)
Press the AUTObutton on the dri-
ver side and/or front/back-seat pas-
senger side: the system will automat-
ically control the air amount and
distribution pattern in the related
passenger compartment areas and
will cancel all the previously made
settings. This condition is marked by
the message FULL AUTOon the
system front and rear display,
besides the leds on the air distribu-
tion buttons turning off.
If one of the functions automatical-
ly controlled by the system (air recir-
culation, air distribution, fan speed
or air conditioner compressor deacti-
vation) is manually adjusted, the
messageFULLon the display turns
off to indicate that the system is no
longer controlling the functions inde-
pendently (apart from temperature
control that is always automatic).

156
Should the system, as a result of
manual settings, no longer be able to
assure the selected temperature in
the various passenger compartment
areas, the selected temperature
value starts flashing to indicate the
system difficulty and the message
AUTOautomatically turns off.
To restore the system automatic
control at any moment after one or
more manual setting, press button
AUTO.MONO button
(set temperature and air distrib-
ution alignment) (16 fig. 121)
Press the MONObutton to auto-
matically align the front/back-seat
passenger’s side temperature and air
distribution to the temperature air
distribution on driver’s side.
Consequently, the temperature and
air distribution in the two areas can
be set simply by turning the knob on
driver’s side. This function is provided
to facilitate adjusting the temperature
in the passenger compartment when
only the driver is present.
To restore separate temperature and
air distribution control in the two
passenger compartment areas, rotate
knob8 (fig. 121) or1 (fig. 122) to set
up temperature in the front/back-
seat passengers’ area or press again
buttonMONO 16(fig. 121) when the
button led is on.REAR button (rear control panel
activation) (11 fig. 121)
Press the REARbutton to switch
the rear control panel on and to cut
out the front control panel. As a
result, back-seat passengers can
select temperature, air distribution
and fan speed according to their
needs.
When rear controls are activated,
the led on button REARis on.
IMPORTANTThe fan speed can
be adjusted manually also by the
rear control panel, when activated,
but it is the same one for the whole
passenger compartment.

The climate control system can be
deactivated also by the rear control
panel, when operating: press repeat-
edly or keep pressed button 7(fig.
122) until all the fan bars on the dis-
play turn off and message OFFis
displayed.
To exclude the rear control panel,
press again button REAR; the but-
ton led turns off and the front-seat
passenger’s controls are operating
again.
Air recirculation on/off button
(3 fig. 121)
The air recirculation function is
controlled according to three strate-
gies:
– automatic operation (button left
led on);
– forced ventilation on (recircula-
tion always on), the right led on the
button will come on;– forced deactivation off (recircula-
tion always off, air taken from the
outside), both leds on the button will
go off.
The three conditions are obtained
by pressing the air recirculation but-
ton3in sequence.
When the air recirculation function
is automatically controlled by the
system, the left led on the air recir-
culation button is turned on, while
the right led is on or off according to
the actual recirculation conditions
(on or off).
During automatic operation, the
recirculation function is automati-
cally switched on when the pollution
sensor detects the presence of pollut-
ed air, e.g. in cities, queues, tunnels
and during windscreen wiper opera-
tion (due to the characteristic smell
of alcohol). In addition, if the compressor is on
and the outside temperature is over
5 °C, to prevent air polluted by
exhaust gases getting inside the pas-
senger compartment during stops,
the system stops air recirculation
when the car speed is lower than 6
km/h. When the car speed returns
over 12 km/h, the system restores
the previous conditions.
After using the air recirculation
function for a long time (over 15
consecutive minutes), the system
automatically stops it for safety rea-
sons, thus letting air be changed.
When air recirculation manual
control is set (button left led off),
messageFULLon the display is off.

IMPORTANTAir at a temperature
lower than that of the outside air
cannot be let in to the passenger
compartment when the compressor
is off. Furthermore, in particular
environmental conditions, the win-
dows could mist up fast because the
air is no longer dehumidified.
The setting will be stored when the
engine is stopped. Either press √
button again or press the AUTObut-
ton to reset automatic control of the
compressor (in the latter case, the
manual settings will be cancelled).
The led on the √button will go out. IMPORTANTThe air recircula-
tion function will allow, according to
the system operation (i.e. heating or
cooling) to reach the required condi-
tions faster. We recommend not
turning on this function on rainy
and/or cold days as this will consid-
erably increase window misting,
especially if the climate control sys-
tem is off.
In particular climate
conditions (e.g. low out-
side temperature or high
humidity) and with the inside air
recirculation automatic control
on, windows could start misting
up. In this case, press the air
recirculation button and set it to
forced open position (both button
leds off), and increase air flow to
the windscreen, if required.Climate control system
compressor off button (7 fig. 121)
Press the √button, when the but-
ton led is on, to switch the air condi-
tioner compressor off. The led will
go off. By pressing again the button
when the led is off, the system auto-
matic control of the compressor acti-
vation is restored; this situation is
indicated by button led lighting up.
When the air conditioner compres-
sor is off, if the system is no longer
able to keep the requested tempera-
ture, the message FULL AUTOon
the display turns off and the system
deactivates air recirculation to pre-
vent window misting up. Instead, if
the system is still able to maintain
the requested temperature, the mes-
sageFULLon the display will stay
on.

159
The air let into the passenger com-
partment cannot be cooled when the
compressor is off. Consequently:
– if the outside temperature is
lower than the set temperature, the
system works normally and can
reach and maintain the set tempera-
ture also when the compressor is off;
– if the outside temperature is
higher than the set temperature, the
system cannot reach the required
temperature. This will be signalled
by flashing the external temperature
value on the display.
When the compressor is off, it is
possible to reset manually the fan
speed; on the contrary, when the
compressor is on and the engine is
running, manual ventilation cannot
be lower than the bar indicated on
the display. Button for fast windscreen
demisting/defrosting (15 fig. 121)
Press this button: the climate con-
trol system will automatically switch
on all the functions required for fast
windscreen and side window demist-
ing/defrosting, that is:
– climate control system compres-
sor on;
– air recirculation off (if on);
– maximum air temperature (HI)
on both displays;
– fan speed according to engine
coolant temperature in order to limit
letting cold air into the passenger
compartment for demisting the win-
dows;
– air flow directed to the wind-
screen and front side window vents;
– heated rear window, external
rearview mirror and windscreen noz-
zle resistances on.The fast windscreen demisting/
defrosting function stays on for
approx. 3 minutes after the engine
coolant temperature exceeds 50 °C
(petrol versions) or 35 °C (diesel
versions).
When the fast demisting/defrosting
function is on, the led on the related
button and that on the heated rear
window button are lighted, while
both leds on the air recirculation
button and that on button √turn
off. Message FULL AUTOon the
display will turn off.
Only the fan speed can be adjusted
and the heated rear window can be
switched off when the fast demist-
ing/defrosting function is on.
Press the fast demisting/defrosting
button again or air recirculation
button or compressor off button to
switch the fast demisting/defrosting
function off and reset the previous
system operation conditions as well
as the last set function.
