INDEPENDENT ADDITIONAL HEATER
(for versions/markets where provided)
The vehicle is available, on request, with two different in-
dependent 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 tempera-
ture and coolant conditions are present. Deactivation is
always automatic.
IMPORTANT During periods with low outdoor temper-
atures when the device cuts in, check that the fuel level
is always higher than the reserve level. Otherwise the de-
vice could lock and require the assistance of a Fiat Deal-
ership.
The heater burns fuel in the same way as
the engine, though to a lesser extent. To
prevent poisoning and asphyxiation, the supple-
mentary 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 en-
gine off;
❒
defrosting the windows;
❒
heating the engine coolant and consequently the actu-
al engine prior to starting.
The system consists of:
❒
a diesel burner to heat the water with an exhaust si-
lencer 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 sys-
tem 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. 54 for turning the heater on man-
ually or programming the time it comes on.
