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.

The fan speed is shown by the bars lit up on the display:
❒Max. fan speed = all bars lit;
❒Min. fan speed = one bar lit.
The fan can be disabled only if the climate control
compressor has been switched off by pressing button
F-fig. 53.
IMPORTANT To restore automatic fan speed control
after a manual adjustment, press the AUTO button.
IMPORTANT At high vehicle speeds, the dynamic effect
may increase the flow of air into the passenger
compartment, which in this case will not directly
correspond to the fan speed bar display.
AUTO button (A)
(automatic operation)
When the AUTO button is pressed the
system automatically regulates the
quantity and the distribution of the air
introduced into the passenger
compartment cancelling all the previous
manual adjustments.
The message FULL AUTO will appear on the front
display in this condition.
By manually adjusting at least one of the functions
automatically managed by the system (air recirculation,
air distribution, fan speed or switching off the
compressor), the word FULL will disappear from the
display, indicating that the system is no longer
automatically controlling all the functions (the
temperature will still be controlled automatically).
▲
˙Air flow distribution split between the windscreen
and front side windows defrosting/demisting vents
and the central and side dashboard vents. This
distribution makes it possible to maintain good levels
of comfort and keep the passenger compartment
sufficiently cool (useful in the summer).

It is however not advised to use it on rainy/cold days as
it would considerably increase the possibility of the
windows steaming up, especially if the climate control
compressor is off.
To prevent steaming up, the recirculation is forced off
(i.e. air is introduced from the outside) when the the
outside temperature is cold.
It is advisable not to use the air recirculation function
when the outside temperature is low to prevent the
windows from rapidly misting up.
Climate control compressor on/off
button (F)
Pressing the √button switches the
climate control compressor off, it if was
on previously and the logo in the display
goes out.
Press the button when the LED is off to restore
automatic system control of compressor activation.
The icon will light up on the display.
The system will switch recirculation off when the
compressor is switched off to prevent misting up.
Although the system is capable of maintaining the
required temperature, the word FULL will disappear
from the display. If the system is no longer able to
maintain the temperature, the figures will flash and the
word AUTO will go out. IMPORTANT Should the system (after manual
intervention) no longer be able to guarantee the target
temperature for the passenger compartment, the set
temperature value will start flashing to indicate the
difficulties the system is experiencing and then the word
AUTO will go out.
To restore system automatic control at any time, after
one or more manual adjustments, press the AUTO
button.
Air recirculation on/off button (G)
The Air recirculation works according to
the following operating logics:
❒override on (air recirculation always on), indicated
by the LED on the button
Gcoming on and the
symbol íon the display;
❒override off (air recirculation always off and
introduction of outside air), indicated by the LED
on the button going off and the symbol êappearing
on the display.
These operating conditions are obtained by pressing air
recirculation button G in sequence.
IMPORTANT The engagement of the air recirculation
system makes it possible to reach the required heating
or cooling conditions faster.

IMPORTANT With the compressor off, it is not
possible to introduce air into the passenger
compartment at a temperature lower than that of the
outside air. In certain weather conditions, the windows
could mist up rapidly due to the non-dehumidified air.
The system remembers that the compressor has been
switched off, even after the engine has stopped.
To restore automatic compressor activation control,
press the √button again (in this case, the system will
work only as a heater) or press the AUTO button.
With the compressor switched off, if the outside
temperature is higher than the one set, the system is
not capable of satisfying this request. This is signalled by
the target temperature flashing, after which the word
AUTO goes out.
With the climate control compressor off, the fan speed
can be set to zero manually (no bar shown).
With the compressor enabled and the engine started,
the fan speed may be reduced to the minimum setting
(only one bar shown).
Button for rapid window demisting/
defrosting (D)
When this button is pressed, the climate
control automatically activates all the
functions necessary to speed up the
demising/defrosting of the windscreen
and the side windows:❒turns on the climate control compressor when
weather conditions are suitable;
❒air recirculation switching-off;
❒sets the maximum temperature for the HI air in both
zones;
❒sets the fan speed set according to the engine
coolant temperature to limit the flow of air that is
insufficiently warm to demist the windows;
❒directs the air flow to the windscreen and front side
windows vents;
❒switches on the heated rear window.
IMPORTANT The rapid demisting/defrosting function
for the windows remains on for about 3 minutes from
when the engine coolant reaches the appropriate
temperature for a rapid demisting of the windows.
When this function is active, the LED on the
corresponding button and the one on the heated rear
window button switch on. The message FULL AUTO
goes off on the display.
You can only adjust the fan speed and switch off the
heated rear windscreen manually when this function is
active.
To restore the operating conditions, prior to activation,
simply press button B, air recirculation button G, the
compressor button F or the
AUTO button A.

(In winter) the additional heater provides heat,
maintains the temperature and circulates the engine
coolant for the preset time in order to ensure the
optimum temperature conditions of the engine and the
passenger compartment when the engine is started up.
The heater can operate automatically when
programmed with a digital timer or manually by pressing
the “immediate heating” button on the timer.
After heater activation, either programmed or manual,
the electronic control unit operates the liquid
circulation pump and ignites the burner in accordance
with the preset, controlled procedures.
The circulation pump output is also controlled by the
electronic control unit in order to minimise the initial
heating time. When the system operates, the control unit turns on
the passenger compartment heater unit fan at the
second speed.
The thermal power of the boiler is regulated
automatically by the electronic control unit depending
on the temperature of the engine coolant.
IMPORTANT The heater is equipped with a thermal
limiter that cuts off combustion in the case of
overheating due to insufficient coolant/coolant leaks. In
this case, after repairing the fault in the cooling system
and/or topping up the fluid, press the program selection
button before turning the heater back on.
The heater can turn off spontaneously due to misfiring
after start-up or because the flame goes out during
operation. In this case, carry out the turning off
procedure and try to turn the heater back on. If it still
does not work, consult a Fiat Dealership.
Activation of the heating system
When an automatic climate control system is present,
the control unit sets the air temperature and
distribution when the heater is turned on from the park
position. When a manual heater/climate control is
present, to obtain maximum heater efficiency, check
that the passenger compartment heating/ventilation
temperature adjustment knob is in the ‘hot air’ position.
To prioritise passenger compartment pre-heating, set
the air distribution knob to the
©position.
