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 checked at a
Fiat Dealership.
NoteThe system uses R134a coolant
which does not pollute the environment
in the event of accidental leakage.
Never use R12 fluid, which is not
compatible with the system
components.AUTOMATIC
CLIMATE CONTROL
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 variation of the
air flow);
❒compressor activation (for cooling/
dehumidifying 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).
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 except
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 temperature of the air sent is
always controlled automatically,
depending on the temperature set in
the display (except when the system is
off or in certain conditions when the
compressor is switched off).
35

CONTROLS
Air temperature
adjustment knob (I)
Turn the knob either clockwise or
counterclockwise to increase or lower
the requested temperature in the
passenger compartment.
The set temperature 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).
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 anticlockwise
and set the required temperature.Air distribution buttons
(B)
By pressing these buttons, it is possible
to set one of the seven possible air
distributions manually:
Air flow to the windscreen and front
side window vents to demist or defrost
them.
Air flow to the central and side
dashboard vents to ventilate chest and
face during the hot season.
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 distributed 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 distributed between the
footwell vents and the windscreen
and front side window defrosting/
demisting vents. This allows an
adequate warming of the passenger
compartment and prevents the
windows from misting up.
37

Air recirculation on/off
button (G)
The air recirculation is managed
according to the following operating
logic:
❒override on (inside air recirculation
always on), indicated by the LED
on button G and the
symbol on
the display;
❒override off (air recirculation
constantly off with air intake from the
outside), signalled by the LED in
the button switching off and by the
symbol in the display
disappearing.
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.
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
control compressor is off.
To prevent the windows from misting
up, the recirculation is forced off (i.e. air
is drawn in from the outside) when
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
enablement/off button
(F)
Press button
to switch the climate
control compressor off (if on). The icon
on the display will go 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 windows from misting up.
Although the system is capable
of maintaining the required
temperature, the word FULL will
disappear from the display. If, on the
other hand, it is no longer capable
of maintaining the temperature, the
letters flash and the word AUTO goes
out.IMPORTANT With the compressor off, it
is not possible to introduce air cooler
than ambient temperature into the
passenger compartment. Furthermore,
in certain conditions, the windows
could mist up rapidly because the air is
not dehumidified.
The system remembers that the
compressor has been switched off,
even after the engine has stopped.
To restore automatic compressor
control, press the
button again (in
this case, the system will only work 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).

ADDITIONAL
HEATER
(for versions/markets, where provided)
On some versions, an additional heater
is also present beneath the driver's
seat. The fan for this heater is operated
by means of the button F located on
the control panel fig. 53.
INDEPENDENT
ADDITIONAL
HEATER
(for versions/markets, where provided)
The vehicle is available, on request,
with two different independent heaters:
one fully automatic, the other which
can be programmed.
AUTOMATIC VERSION
The additional heater is turned on in
automatic mode when the engine
is started and the required outside
temperature and coolant conditions are
present. Deactivation is always
automatic.
21)
IMPORTANT During periods with low
outdoor temperatures when the device
cuts in, check that the fuel level is
always higher than the reserve level.
Otherwise the device could lock and
require the assistance of a Fiat
Dealership.PROGRAMMABLE
VERSION
The additional heater operates
completely independently of engine
operation and allows the following:
❒heating the passenger compartment
with the engine off
❒defrosting the windows;
❒heat the engine coolant and then the
engine itself prior to starting.
The system consists of:
❒a diesel burner for heating the water
with an exhaust silencer for the
combustion gases;
❒a metering pump connected to the
reservoir pipes for supplying the
burner;
❒a heat exchanger connected to the
engine cooling system pipes;
❒a control unit connected to the
passenger compartment
heating/ventilation system to allow
automatic operation;
❒an electronic control unit for
controlling and adjusting the built-in
burner;
❒a digital timer fig. 54 for turning the
heater on manually or for
programming the time that it comes
on.
MODEF
53F1A0305
41

The additional heater (during winter)
heats, maintains the temperature of and
circulates engine coolant for a set time
period in order to ensure optimum
engine and passenger compartment
conditions at engine start-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, whether
programmed or manually, the electronic
control unit operates the coolant pump
and turns on the burner in accordance
with pre-set, 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.
To prioritise windscreen demisting, set
the air distribution knob to
position.
To obtain both functions, set the air
distribution knob to
position.
