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.

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.
