SUPPLEMENTARY HEATER
INDEPENDENT
(for markets/versions, 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.
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.
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
PROGRAMMABLE VERSION
The additional heater operates completely
independently of engine operation and allows the
following:
❒heating the vehicle passenger compartment with the
engine off;
❒defrosting the windows;
❒heating the engine coolant and consequently the
engine itself prior to starting.
The system consists of:
❒a diesel burner to heat the water with an exhaust
silencer for the combustion gases;
❒a metering pump connected to the vehicle tank
pipes, to supply 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 control and operation
of the burner in the heater;
❒a digital timer A-fig. 55 for turning the heater on
manually or programming the time it comes on.

(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.

the time will disappear from the display and remain
stored and the number 3 will light up in the display.
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.
