SYSTEM SERVICING
In winter, the climate control system must be turned on
at least once a month for about 10 minutes. Before
summer, have the system inspected at a Fiat Dealership. HEATED REAR WINDSCREEN AND DOOR

The system uses R134a refrigerant fluid
which does not pollute the environment
in the event of accidental leakage. Under
no circumstances should R12 fluid be used as it is
incompatible with the system components.

The intake air temperature is always automatically
controlled according to the temperature set on the display
(except for when the system is off or in certain conditions
when the compressor is not running).
The system allows the following parameters and
functions to be set or altered manually: air temperature,
fan speed (continuous variation); air distribution in
seven positions; compressor enablement, fast
defrosting/demisting function; air recirculation; switching
off of the system;

SYSTEM
(for versions/markets, where provided)
GENERAL INFORMATION
The automatic climate control system adjusts the
temperature, the quantity and the distribution of the air
in the passenger compartment.
The temperature control is based on the “equivalent
temperature”: in other words, the system continuously
works to keep the comfort level inside the vehicle
constant and to compensate for possible variations in
outside conditions, including the sun’s rays detected by
a dedicated sensor. The automatically controlled
parameters and functions are:
❒air temperature at the vents;
❒air distribution at the vents;
❒fan speed (continuous air flow variation);
❒compressor activation (to cool/dehumidify the air);
❒air recirculation.
All functions may be changed manually. In other words,
you may select one or more functions and change the
parameters as required. Automatic control of the
manually changed functions will be suspended: the
system will override your settings only for safety-related
reasons (e.g. risk of misting up). Manual selections will
always take priority over automatic settings and will be
stored until the user switches the system back to
automatic operation by pressing the AUTO button again
expect for the cases in which the system will intervene
for particular, safety-related reasons. You can adjust one
function manually without affecting the automatic
control of the others.

USING THE CLIMATE CONTROL SYSTEM
The system can be started in different ways, but it is
advisable to start by pressing the AUTO button and
then turning the knob to set the temperature required
on the display. The system will start running
automatically in this way and the set temperature will be
reached as quickly as possible. The system will adjust
the temperature, the quantity and the distribution of the
air introduced into the passenger compartment and, by
managing the recirculation function, the activation of the
compressor. During fully automatic operation, the only
manual intervention required is the possible activation
of the following functions:
❒Òair recirculation, to keep it always on or off;
❒Zto speed up demisting/defrosting of the front
windows, rear window and door mirrors.During fully automatic system operation, you can change
the set temperature, air distribution and fan speed at
any time by using the relevant buttons or knobs: the
system will automatically change its settings to adjust to
the new requirements. During fully automatic operation
(FULL AUTO), the word FULL will disappear if the air
distribution and/or flow rate and/or engagement of the
compressor and/or recirculation settings are changed.
In this way, the functions will switch from automatic to
manual control until the AUTO button is pressed again.
With one or more functions turned on manually, the
adjustment of the intake air temperature continues to
be managed automatically, except with the compressor
switched off: if this is the case, the temperature of the
air introduced into the passenger compartment cannot
be lower than that of the outside air.
CONTROLS

Turn the knob either clockwise or
anticlockwise to increase or lower the
requested temperature in the passenger
compartment.
The temperature set is shown on the display.
Turn the knob either fully to the right or fully to the left
to the extreme HI or LO position to turn the maximum
heating or maximum cooling functions on:
❒HI Function (maximum heating):
select by turning the temperature knob clockwise
beyond the maximum value (32 °C).

Air distribution buttons (B)
Press these buttons to manually set one
of the seven air distribution settings:
▲Air flow to the windscreen and front side window
vents to demist or defrost the windows.
˙Air flow to the central and side dashboard vents to
ventilate the chest and the face in hot weather.
▼Air flow to the front and rear footwell vents. Thanks
to the natural tendency of hot air to rise, this
distribution pattern allows the passenger
compartment to warm up as quickly as possible,
providing an immediate feeling of warmth.
˙
▼Air flow distribution split between footwell vents
(hotter air) and central and side dashboard vents
(cooler air). This distribution mode is particularly
useful in spring and autumn on sunny days.
▲
▼Air flow distribution split between the footwell vents
and the windscreen and front side windows
defrosting/demisting vents. This allows an adequate
warming of the passenger compartment and
prevents the windows from steaming up.
This function may be used to heat up the passenger
compartment by exploiting the system’s potential to the
full. In this event, the system stops controlling the
temperature automatically and sets the air mixing to
maximum heating. The air speed and distribution are
fixed.
In particular, if the heating fluid is not sufficiently hot,
the maximum fan speed does not come on straight away
in order to limit the intake of insufficiently hot air to the
passenger compartment.
All manual settings will be allowed when this function
is on.
To switch the function off, simply turn the temperature
knob anticlockwise and set the required temperature.
❒LO function (maximum cooling):
select by turning the temperature knob anticlockwise
beyond the minimum value (16 °C).
This function may be used to cool down the passenger
compartment by exploiting the system’s potential to the
full. In this event, the system stops controlling the
temperature automatically and sets the air mixing to
maximum cooling. The air speed and distribution are
fixed. All manual settings will be allowed when this
function is on.
To switch the function off, simply turn the temperature
knob clockwise and set the required temperature.
