INTERNAL AIR RECIRCULATION
ACTIVATION
Turn the knob D to
Ò.
It is advisable to switch the internal air recirculation on
while standing in queues 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.
IMPORTANT The inside air recirculation system makes
it possible to reach the required heating or cooling
conditions faster.
Do not use the air recirculation function on rainy/cold
days as it would considerably increase the possibility of
the windows misting inside.
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
MIRRORS DEMISTING/DEFROSTING fig. 52
(for versions/markets where provided)
Press the button A to activate this function; when this
function is on the warning light in the button comes on.
This function is timed and will turn off automatically
after 20 minutes. Press the button A again to switch the
function off.
IMPORTANT Do not apply stickers on the inside of the
rear window over the heating filaments to avoid damage
that might cause it to stop working properly.
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.

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.

(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.

IMPORTANT The preselected activation time can be
changed or deleted by following the above instructions.
Switching the heating system off
Deactivation of the system, depending on the type of
activation (automatic or manual), may be:
❒automatic,at the end of the preset activation time
(60 minutes with lighting of the red display);
❒manualpressing the “immediate heating” button on
the timer again (flame button 1).
In both cases the heating warning light and the display
lighting go out and the passenger compartment heater
unit fan and the combustion stop.
F0N0155mfig. 60
The fluid circulation pump continues to work for
around two minutes to dissipate as much heat as
possible from the heater; the heater can be turned back
on during this stage.
The heater burns fuel in the same way
as the engine, though to a lesser extent.
To prevent poisoning and asphyxiation, the
supplementary heater must never be turned on,
even for short periods, in closed environments
such as a garage or workshops without
extraction fans for the exhaust gases.
WARNING
IMPORTANT When parked the heater switches off
when the battery voltage is low to allow the engine to
be started up.

IMPORTANT Before switching the device on, check
that the fuel level is higher than the reserve level.
Otherwise the device could lock and require the
assistance of a Fiat Dealership.
❒Always turn off the heater when refuelling and near
service stations to avoid the risk of explosion or fire
hazards.
❒Do not park the vehicle on inflammable material
such as paper, grass or dry leaves: fire hazard!
❒The temperature near the heater should not exceed
120 °C (e.g. during stove painting in a body shop).
The electronic control unit components may be
damaged at higher temperatures.
❒Whilst the heater is operating with the engine
switched off, it absorbs energy from the battery; the
engine should therefore be left running for a while to
make sure that the battery is properly recharged.
❒To check the coolant level, follow the instructions in
the “Vehicle maintenance” chapter in the “Engine
coolant system fluid” paragraph. The water in the
heating circuit must contain a minimum percentage
of 10% antifreeze.
❒For maintenance and repairs, only contact Fiat
Dealerships and only use genuine spare parts.
F0N0233mfig. 61
MAINTENANCE
Have the additional heater checked regularly at a Fiat
Dealership (and always at the start of every winter).
This will guarantee safe and economic operation of the
heater as well as a long duration.
