SELF-STANDING SUPPLEMENTARY
HEATER (where provided)
The vehicle can be equipped, upon re-
quest, with two different self-standing
heaters:one is totally automatic
whereas the other is programmable.
AUTOMATIC VERSION
The supplementary heater is totally in-
dependent from the engine.
This heater is switched on automat-
ically (if required) when turning the ig-
nition key to MAR. LOOKING AFTER THE
SYSTEM
During the winter, the climate con-
trol system must be turned on at least
once a month for about ten minutes.
Before summer, have the system
checked at a Fiat Dealership.PROGRAMMABLE VERSION
The supplementary heater is totally
independent from the engine and can
be used to:
– heat the passenger compartment
when the engine is off;
– defrost the windows;
– heat the engine coolant and con-
sequently the engine before starting.
The system consists of:
– a diesel burner to heat coolant with
exhaust fume muffler;
– a metering pump connected to the
vehicle fuel pipes to feed the burner;
– a heat exchanger connected to the
engine cooling system pipes; The system is filled with
R134a refrigerant which
will not pollute the envi-
ronment in the event of leakage.
Under no circumstances should
R12 fluid be used as it is incom-
patible with the system compo-
nents and contains CFC.
The heater burns fuel in the
same way as the engine,
though, of course, to a lesser degree
and therefore to avoid intoxication
and suffocation, never use the sup-
plementary heater in closed areas,
garages or workshops not equipped
with specific exhaust evacuation
devices even for short periods of
time.

– a control unit connected to the
heater/ventilation unit for automatic
operation;
– an electronic control unit to check
and adjusted the integrated heater
burner;
– a digital timer A-fig. 85to start the
heater manually or to program staring
time.In cold weather, the supplementary
heater automatically warms and cir-
culates constant temperature fluid in
the engine cooling system for the time
required to ensure optimal engine ig-
nition and cab temperature conditions.
The heater can be started automat-
ically (programmed by means of the
digital timer) or manually by pressing
the “heat now” button on the timer.
When the heater is turned on (au-
tomatically or manually), the electronic
control unit operates the fluid circu-
lation pump and safely ignites the burn-
er.The electronic control unit also con-
trols the circulation pump delivery in
order to reduce initial heating time.
When the fluid reaches a temperature
of 30°C, the control unit operates the
passenger compartment ventilation
fan.
When the fluid temperature reaches
72°C, the electronic control unit re-
duces the burner power and stops op-
eration when it reaches 76.5°C. The
timer, circulation pump and heater fan
are kept running. When the fluid tem-
perature drops under 71°C the con-
trol unit automatically turns the burn-
er back on.

IMPORTANTTo recall other pre-
set times, press button 6within 10
seconds.
– press button 5or 7to select the
starting time required within 10 sec-
onds.
IMPORTANTStarting time disap-
pears and the number 3(correspond-
ing to the selected preset time) ap-
pears on the display to confirm the
starting time has been entered.
Deleting a programmed
starting time fig. 89
To delete the programmed starting
time, press button 6briefly: the dis-
play light will go off and number 3cor-
responding to the selected preset
time will disappear.Recalling a pre-set time fig. 90
Press the button 6repeatedly until
the required preset starting time ap-
pears on the display (number 3). After
10 seconds, the time will disappear,
number 3and the display will light up
thus confirming starting time has been
entered.
IMPORTANTTo change or delete
pre-set times, follow the instructions
in the paragraphs above.Turning the heater off
According to the operation mode
(automatic or manual), the heater can
be turned off:
–automatically,after the preset
period of time (60 minutes when the
display light is red);
– manuallyby pressing the “heat
now” button on the timer.
In each case, the heater warning light,
the display and the passenger com-
partment fan will be turned off and the
heater flame will be blown out.
The coolant circulation pump will
run for approximately two minutes af-
ter the heater has been turned off to
dispose of as much heat as possible.
During this phase the heater can, how-
ever, be turned on.

DIESEL ENGINES
The vehicle must only
be filled with diesel fuel
for motor vehicles, in
compliance with European Spec-
ification EN590. The use of other
products or mixtures may ir-
reparably damage the engine
with invalidation of the warran-
ty due to the damage caused. In
the event of accidentally filling
with another type of fuel, do not
start the engine and empty the
tank. If the engine has been run
even for only a very short time,
in addition to the tank, it is also
necessary to drain out the whole
fuel circuit.AT THE FILLING
STATION
PETROL ENGINES
Use unleaded petrol only.
However, to avoid mistakes, the fu-
el filler is too small for the leaded
petrol pump.
Octane rating (R.O.N.) must not be
lower than 95.
fig. 151
F0D0193m
Never put even the tini-
est amount of leaded
petrol in the fuel tank of
your Ducato even in an emer-
gency. You would damage the
catalytic converter beyond re-
pair.
An inefficient catalytic
converter will allow
harmful exhaust fumes to
be emitted and thus contribute
to air pollution.

104GETTING TO KNOW YOUR VEHICLE
IMPORTANTThe airtight seal of
the cap may lead to a slight increase of
pressure in the tank. A hissing sound
when the cap is removed is therefore
quite normal.
After refuelling, screw the cap until
hearing one or more clicks, turn the
key and then remove it.. close the lid.
IMPORTANTMoreover, before
starting the engine, for the sake of
safety, check whether the refuelling
gun is properly hung onto the fuel
pump.If required, replace the
fuel cap with another gen-
uine cap to avoid affecting
the efficiency of the fuel vapour
recovery system.

PROTECTING THE
ENVIRONMENT
Protection of the environment has
been the guiding principle in the design
of the Fiat Ducato right from the start.
The result is the use of materials and
creation of devices that can reduce or
considerably curtail harmful influences
on the environment.
The devices for curtailing petrol en-
gine emissions are:
– a three-way catalytic converter;
– a lambda sensor;
– a fuel evaporation system.
The devices for curtailing diesel en-
gine emissions are:
– an oxidising catalytic converter;
– an exhaust gas recirculation system
(E.G.R.) (for certain versions).
Consequently, the Fiat Ducato is
ready to travel well ahead of the most
stringent international pollution control
standards.
Keep naked flames or light-
ed cigarettes away from
the fuel filler hole as there is a dan-
ger of fire. Do not bend too close to
the hole either so as not to breathe
in harmful vapours.
