catalytic converter FIAT DUCATO 244 2005 3.G Owners Manual

MUST BE READ!
REFUELLING
Petrol engines:only refuel with unleaded petrol with octane rating (RON) no less than 95.
Diesel engines:only refuel with diesel fuel conforming to the European specification EN590.
STARTING THE ENGINE
Make sure the handbrake is pulled up; put the gear lever to neutral; press the clutch pedal down to the floor
without touching the accelerator; then:
automatic gearbox:for operation and use, strictly follow instructions and warnings contained at paragraph
“Automatic gearbox” in section “Getting the best out of your vehicle”.
petrol engines:turn the ignition key to AVV and release it as soon as the engine starts.
diesel engines:turn the ignition key to MARand wait for the instrument panel warning light mand Y
to go out; then turn the ignition key to AVV and release it as soon as the engine starts.
PARKING OVER INFLAMMABLE MATERIAL
When functioning normally, the catalytic converter reaches high temperatures. For this reason do not park
the vehicle over inflammable material, grass, dry leaves, pine needles, etc.: fire hazard.

102GETTING TO KNOW YOUR VEHICLE
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.

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.

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.

LOOKING AFTER EMISSION
CONTROL DEVICES
The correct use of pollution control
devices not only ensures respect for
the environment but also has an effect
on the vehicle’s performance.
Keeping these devices in good con-
ditions is therefore a fundamental rule
for driving that is easy on your pock-
et and on the environment too.
The first step to take is to follow the
Service Schedule to the letter.
If your vehicle has a petrol engine
with catalytic converter use only un-
leaded petrol.
if you have trouble starting, do not
keep turning the ignition key for long
periods. Be especially careful to avoid
bump starting the vehicle by pushing,
towing or rolling downhill: these are
all manoeuvres that can damage the
catalyst.
Use an auxiliary battery for start-ups
only.If the engine begins to “loose its
smoothness” when travelling, contin-
ue your journey but reduce the de-
mands you are making on the engine
and have the vehicle seen to at a Fi-
at Dealershipas soon as you can.
When the instrument panel fuel re-
serve warning light comes on, fill up as
soon as possible. A low fuel level may
cause an uneven supply of fuel to the
engine with inevitable increase in the
temperature of the exhaust gas and se-
rious damage to the catalytic con-
verter.
Never run the engine with one or
more spark plugs disconnected, even
for testing purposes.
Do not warm up the engine by let-
ting it idle for a while before moving
off unless the outside temperature is
very low and, even in this case, only
do so for less than thirty seconds.
Do not install heat shields and do not
remove those already fitted to the cat-
alytic converter and exhaust pipe.
Do not allow anything to
be sprayed onto the cat-
alytic converter, lambda sensor and
exhaust pipe.
WARNING
Ignoring the above rules
may lead to fire.
WARNING
When functioning normal-
ly the catalytic converter
reaches high temperatures. For this
reason do not park the vehicle over
inflammable material (grass, dry
leaves, pine needles, etc.): fire haz-
ard.
