LOOKING AFTER THE SYSTEM
During winter, the climate control system
must be turned on at least once a month
for about 10 minutes. Before summer,
have the system checked at a Fiat Deal-
ership.
The system is filled with
R134a refrigerant which will
not pollute the environment
in the event of leakage. Un-
der no circumstances should R12 fluid
be used as it is incompatible with the
system components.AUTOMATIC CLIMATE
CONTROL SYSTEM
(where provided)
GENERAL
The vehicle is fitted with an automatic cli-
mate control system which makes it pos-
sible to adjust air flow, air temperature
and air distribution in the passenger's com-
partment. 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 vari-
ation of the outside climate conditions, in-
cluding sunshine detected by a proper sen-
sor provided for the purpose.
The climate control system automatically
controls and adjusts the following para-
meters and functions:
❒air temperature at vents;
❒air distribution at vents;
❒fan speed (continuous air flow varia-
tion);
❒compressor activation (to cool/dehu-
midify air);
❒air recirculation.All the above functions can be changed
manually by selecting the required func-
tion/s and by changing the set parameters.
In this way the automatic control is de-
activated; the system will resume auto-
matic control only for safety reasons (e.g.
risk of window misting up).
Manual selections prevail over automatic
ones and remain in storage until the user
decides to resume automatic control by
pressing again button AUTO, except when
the system cuts in for particular safety
conditions.
The control of functions not changed man-
ually remains automatic.
The temperature of the air admitted to
the passenger compartment is always con-
trolled automatically according to the tem-
peratures set on the display (except when
the system is off or under certain condi-
tions when the compressor is off).

SWITCHING THE CLIMATE
CONTROL SYSTEM ON
The system can be started in different
ways, but it is advisable to press the AU-
TO button and then to turn the knob to
set the temperatures required on the dis-
play.
This way the system will start working
completely automatically to reach the
comfort temperature as quickly as possi-
ble. The system will set air temperature,
quantity and distribution and it will con-
trol the air recirculation function and the
activation of conditioner compressor.During fully automatic operation, the on-
ly manual settings required are the fol-
lowing:
❒Òair recirculation, to keep it always
on or off;
❒Zto speed up demisting/defrosting of
windscreen, front side windows, rear
window and door mirrors;
During full automatic system operation,
you can change at any time set tempera-
ture, air distribution and fan speed by us-
ing the relevant buttons or knobs: the sys-
tem will automatically change its settings
to adjust to the new requirements. During FULL AUTO operation, changing
air distribution and/or flow and/or com-
pressor activation and/or air recirculation
will make the FULL wording disappear. In
this way functions will pass from automatic
control to manual control until pressing
again the AUTO button. With one or
more functions engaged manually, the ad-
justment of the temperature of the air ad-
mitted to the passenger compartment
continues to be controlled automatically
by the system, except with the climate
control compressor off: under this condi-
tion in fact, the temperature of the air ad-
mitted to the passenger compartment
cannot be lower than outside air temper-
ature.

Air temperature
adjusting knob (I)
temperatura
Turning the knob
clockwise or counter-clockwise,
respectively raises or lowers the
temperature of the air required in the
passenger compartment.
Set temperature is shown on the
display.
Turning the knob fully clockwise or
counter-clockwise until it reaches the ex-
treme selections HI or LO, the maximum
heating or cooling functions are respec-
tively engaged:
❒HI function (highest heating power):
this is turned on by rotating the temper-
ature knob clockwise and passing the max.
temperature value (32 °C).
This function can be engaged when re-
quiring to heat the passenger compart-
ment as quickly as possible, exploiting the
maximum potential of the system. Under
these conditions, the system is no longer
controlled by the automatic temperature
adjustment system and sets air mixing to
maximum heating by modulating speed
and air distribution.
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 possible with this
function on.To switch the function off, simply turn the
knob counter-clockwise and set the re-
quired temperature.
❒LO function (highest cooling power:
this is turned on by rotating the temper-
ature knob counter-clockwise and passing
the min. temperature value (16 °C).
This function can be engaged when re-
quiring to cool the passenger compart-
ment as quickly as possible, exploiting the
maximum potential of the system. Under
these conditions, the system is no longer
controlled by the automatic temperature
adjustment system and sets air mixing to
maximum cooling by modulating speed
and air distribution. All manual settings are
possible with this function on.
To switch the function off, simply turn the
knob clockwise and set the required tem-
perature.

Air distribution
buttons (B)
Pressing these buttons it
is possible to choose manually one of the
seven possible air distributions:
▲Air flow to the windscreen and front
side window vents to demist or de-
frost them.
˙Air flow at central and side dashboard
vents to ventilate the chest and the
face during the hot season.
▼Air flow towards the front and rear
lower parts of the passenger com-
partment. Due to the natural tenden-
cy of heat to spread upwards, this type
of distribution allows heating of the
passenger compartment in the short-
est time, also giving a prompt feeling
of warmth.
˙Splitting of the air flow between the ▼vents to the lower part of the pas-
senger compartment (warmest air)
and the dashboard centre and side
outlets (coolest air). This air flow dis-
tribution is particularly useful in spring
and autumn when the sun is shining.
▲Splitting of the air flow between the ▼windscreen and front side window
demisting/defrosting vents and the
lower part of the passenger compart-
ment. This type of air distribution al-
lows satisfactory heating of the pas-
senger compartment while preventing
possible misting of the windows.
▲Splitting of the air flow between the ˙windscreen and front side window
demisting/defrosting vents and the
dashboard centre and side outlets.
This air flow distribution enables to
obtain satisfactory cooling of the pas-
senger's compartment and to keep the
required cooling condition in summer.
▲Splitting of the air flow between the ˙windscreen and front side window ▼demisting/defrosting vents, dashboard
centre and side outlets and the lower
part of the passenger compartment.
This air flow distribution enables to
keep good overall comfort conditions
both in summer and in winter.
Lighting up of the relevant button leds
shows the type of air distribution select-
ed.
To restore automatic air distribution con-
trol after a manual selection, press button
AUTO.
