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.

Fan speed adjusting
buttons (H)
Press button Hends to
increase or to decrease the fan speed and
therefore the amount of air admitted into
the passenger compartment, the system
will however keep the required
temperature.
The fan speed is shown by the lit bars on
the display
❒Max fan speed = all bars lit
❒Min fan speed = one bar lit.
The fan can be cut off only if the climate
control compressor has been switched off
pressing button F-fig. 51.
IMPORTANT To restore automatic fan
speed control after a manual adjustment,
press button AUTO.
IMPORTANT At high vehicle speed, the
dynamic effect increases the air flow inside
the passenger compartment that will not
be directly correlated with the lit fan
speed bars.AUTO button (A)
(automatic
operation)
Pressing the AUTO
button 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 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 dis-
play. This means that automatic control is
not complete (except temperature control
which is always automatic).

It is however inadvisable to use it on
rainy/cold days as it would considerably
increase the possibility of the windows
misting inside, especially if the climate con-
trol system is off.
With low outdoor temperatures, recir-
culation is turned off (with air intake from
outside) to prevent possible misting.
It is inadvisable to use the inside air re-
circulation function with low outside tem-
perature as windows may mist over quick-
ly.Climate control
compressor on/off
button (F)
Press pushbutton √to
turn off the climate control system
compressor if it was on previously and
the logo on the display is turned off.
When the pushbutton is pressed with
the led off, control of compressor
activation is restored to automatic
control by the system. This condition is
indicated by the logo lighting up on the
display.
When turning the compressor off, the sys-
tem will deactivate air recirculation to pre-
vent window misting up. Although the sys-
tem is able to keep the required tempera-
ture, the wording FULL will disappear from
the display. If the system is no longer able
to keep the required temperature, tem-
perature figures will flash and the wording
AUTO will disappear from the display.IMPORTANT With the climate control
compressor off, it is not possible to admit
air to the passenger compartment with a
temperature below the outside tempera-
ture; moreover, under certain environ-
mental conditions, windows could mist up
fastly since air is not dehumidified.
The switching off of the climate control
compressor remains in storage even when
the engine has been stopped.
To restore automatic control for switch-
ing on the climate control compressor,
press again button √(in this event the sys-
tem will just work as heater) or press but-
ton AUTO.

With the compressor off, if the outside
temperature is higher than set, the system
is not able to meet the request. This is in-
dicated by the temperature setting flash-
ing, after which the AUTO message is
turned off.
With the compressor disabled, it is pos-
sible to zero the fan speed manually (no
bars displayed).
With the compressor enabled and the en-
gine started, the fan speed may only drop
to minimum (one bar displayed).Fast window
demisting/defrosting
button (D)
Press this button: the
climate control system will automatically
switch on all the functions required for
fast windscreen and front side window
demisting/defrosting, that is:
❒switches on climate control compres-
sor when climatic conditions are suit-
able;
❒air recirculation off;
❒maximum air temperature HI on both
areas;
❒activates proper fan speed according
to engine coolant temperature to lim-
it the flow into the passenger com-
partment of air not warm enough to
demist the windows;
❒directs air flow to windscreen and
front side windows vents;
❒turns heated rear window on
IMPORTANT Fast demisting/defrosting
function stays on for about 3 minutes,
since engine coolant temperature reach-
es a temperature suitable for fast window
demisting.
When the max. demisting/defrosting func-
tion is on, the button led and the heated
rear window button led will turn on; FULL
AUTO wording on the display will turn
off.

tem fault and/or topping up the fluid.
The heater can turn itself off after engine
ignition or if the flame goes out. In this
case, turn the heater off manually and at-
tempt to turn it back on again. If you can-
not turn the heater on, contact a Fiat
Dealership.Turning the heater on
If an automatic climate control system is
fitted, the control unit sets air tempera-
ture and distribution when the parking
heater is turned on.
When a manual heater/climate control
system is fitted, to achieve peak heater
performance, check that the passenger
compartment heater/ventilation unit air
temperature knob is in “warm air” posi-
tion.
For preferential passenger compartment
preheating, turn the air distribution knob
to position
©.
For preferential windscreen demisting, set
the air distribution knob to position
