It is advisable to switch the internal
air recirculation on whilst queuing
or in tunnels to prevent the
introduction of polluted air. Do not
use the function for a long time,
particularly if there are many
passengers on board, to prevent
the windows from misting up.

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);
51F1A0330
35

❒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).
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 the
system;

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 sent 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:
❒air recirculation, to keep the
function always either on or off;
❒
to speed up demisting/defrosting
of windscreen, rear window and
external rear view 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 sent into the passenger
compartment cannot be lower than
that of the outside air.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.
37

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.
Air flow distribution split
between the windscreen and front
side windows defrosting/demisting
vents and the central and side
dashboard vents as well as the
footwell vents. This distribution
makes it possible to maintain good
levels of comfort and keep the
passenger compartment sufficiently
cool (summer).
Air flow distributed between
windscreen and front side window
defroster/demister and central
and side dashboard vents. This
distribution allows good air diffusion
and maintains a good level of
comfort both in summer and winter.
The distribution set is shown by
the corresponding LEDs on the
selected buttons coming on.
38
KNOW YOUR VEHICLE
To restore automatic control of the
air distribution after a manual
selection, press the AUTO button.

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 thebutton 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;
MODEF

KNOW YOUR VEHICLE

❒a digital timer fig. 54 for turning the
heater on manually or for
programming the time that it comes
on.
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.

IMPORTANT
43) Keep your speed down when
snow chains are fitted; do not
exceed 50 km/h. Avoid potholes,
steps and pavements and avoid
driving for long distances on
roads not covered with snow to
prevent damaging the vehicle and
the roadbed.
PROLONGED
VEHICLE INACTIVITY
If the vehicle needs to be off the
road for longer than one month, the
following precautions must be
taken:
❒park the vehicle indoors in a dry and,
if possible, well-ventilated place;
❒engage a gear;
❒check that the handbrake is not
engaged;
❒disconnect the negative battery
terminal; if the vehicle is equipped
