Light FIAT DUCATO 2006 3.G Repair Manual

126GETTING THE BEST OUT OF YOUR VEHICLE
CONDITIONS OF USE
Cold starting
Frequent cold starting will not enable
the engine to reach optimal running
temperature. It follows, therefore,
that consumption will be higher (from
+15 to +30% in towns) as will the
production of toxic emissions.
Traffic and road conditions
Heavy traffic and higher consumption
are synonymous: for example, when
driving slowly with frequent use of low-
er gears or in towns where there are
numerous traffic lights.
Winding roads, mountain roads and
bumpy roads also have a negative effect
on consumption.
Enforced halts
During prolonged stops (traffic lights,
level crossings, etc.) the engine should
be switched off.LOAD
RECOMMENDATIONS
The version of the Ducato you are
driving has been designed and ap-
proved on the basis of several set
maximum weights (see the tables
“Weights” in section “Technical spec-
ifications”):
– kerb weight
– payload
– total weight
– total weight on the front axle
– total weight on the rear axle
– towable weight
fig. 10
F0D0047m
Each of these limits must be
borne in mind and MUST
NEVER BE EXCEEDED under any
circumstances. In particular, never
exceed the maximum weight per-
mitted on the front and rear axles
when arranging loads in vehicle (es-
pecially for special version vehicles).
WARNING
Chance knocks or sudden
braking can cause sudden
shifts of the load which could jeop-
ardise the safety of the driver and
the passengers: before you start off
make sure the load is firmly secured
by using the hooks built into the
floor for that purpose fig. 10. Use
metal cables, ropes or straps strong
enough to support the weight of
the load to be fixed.
WARNING

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.
WARNING

129GETTING THE BEST OUT OF YOUR VEHICLE
TOWING A TRAILER
IMPORTANT
The vehicle must be fitted with a ho-
mologated tow hitch and suitable elec-
trical system for towing a caravan or
trailer. Have the tow hitch fitted by an
expert who will issue specific docu-
mentation for use on roads.
Fit special wing mirrors in accor-
dance with the highway code.
Remember that towing a trailer
makes it harder for the vehicle to
climb the maximum gradients speci-
fied, increases braking and overtaking
distance, proportionally to the overall
weight of the trailer.
Engage a low gear when driving
downhill rather than constantly brak-
ing.
The weight the trailer exerts on the
vehicle’s tow hitch coupling reduces
the vehicle’s payload by the same
amount.In order to be sure you are not ex-
ceeding the maximum towing weight
(shown in the log book) you have to
take into account the trailer weight ful-
ly laden including the accessories and
personal luggage.
Do not exceed the speed limits for
towing a trailer in the country you are
driving in. In any case, do not exceed
the top speed of 100 km/h.TOW HITCH INSTALLATION
The tow hitch must be fixed to the
body by an expert in accordance with
the following instructions and re-
specting the additional and/or integra-
tive information provided by the tow
hitch manufacturer.
The tow hitch to be fitted must com-
ply with the current regulations in
force, with reference to Directive
94/20/CEE and subsequent modifica-
tions.
Use a tow hitch suited for the maxi-
mum towable load of the vehicle version
on which the tow hitch is to be fitted.
Use a unified coupling for the elec-
trical connections. The coupling is gen-
erally fitted on a specific mount fas-
tened to the tow hitch.
For the electrical connections, a 7 or
13 pole 12VDC coupling must be used
(CUNA/UNI and ISO/DIN standards).
Follow the instructions provided by
the manufacturer of the vehicle and/or
the tow hitch.
For the electric connections use the
proper trailer light control unit.
Under no circumstances
modify the vehicle’s braking
system for trailer braking control.
The trailer braking system must be
completely independent from the
vehicle hydraulic system.
WARNING
Where your vehicle is
equipped with ABS, re-
member that this has no effect over
the trailer braking system. Particu-
lar care must be taken on slippery
surfaces.
WARNING

130GETTING THE BEST OUT OF YOUR VEHICLE
The electrical brake or other device
(electrical winch, etc.) must be pow-
ered directly from the battery by
means of a lead with a cross-section
area not smaller than 2.5 mm
2.
In addition to the electrical connec-
tions, only the power wire for an ad-
ditional electrical brake and for inter-
nal trailer lighting with a power not
exceeding 15W can be connected to
the vehicle’s electrical system.
FITTING DIAGRAM

An additional tow hitch - specific for
chassis cab and truck versions is shown
in fig. 12. The structure Ømust be se-
cured to the points shown with a total
of twelve M 10 screws.
Fit the tow hitch with the light cluster
crossmember in its original position. If
the crossmember has been removed,
replace it with another crossmember
of the same size and resistance.
IMPORTANTFasten a tag in
clearly visible position at the same
height as the tow hitch. This tag is
compulsory. It must be adequately
sized, made of suitable material and
carry the following information:
MAX ADMITTED LOAD ON

VEHICLE STORAGE
The following precautions should be
taken if the vehicle will not be used for
several months:
– park the vehicle in covered, dry and
if possible well-ventilated premises;
– engage a gear;
– remove the cables from the battery
(first remove the cable to the negative
terminal) and check the battery
charge. If the vehicle is to be stored
for long periods the charge of the bat-
tery should be checked every month
and recharged if it falls below 12.5 V;– make sure the handbrake is not en-
gaged;
– clean and protect the painted parts
using protective wax;
– clean and protect the shiny metal
parts using special compounds readi-
ly available;
– sprinkle talcum powder on the rub-
ber windscreen and rear window
wiper blades and lift them off the glass;
– slightly open the windows;
– cover the vehicle with a cloth or
perforated plastic sheet. Do not use
sheets of non-perforated plastic as
they do not allow moisture on the ve-
hicle body to evaporate;– inflate the tyres to 0.5 bar above
the normal specified pressure and
check it at intervals;
– do not drain the engine cooling sys-
tem.
IMPORTANTWhere relevant,
switch off the electronic vehicle alarm
with the remote control and deacti-
vate the system by turning the emer-
gency key to OFF (see “Electronic
alarm” in section “Getting to know
your vehicle”).

formed on versions with a diesel en-
gine; contact aFiat Dealership.
PETROL VERSIONS
If the Fiat CODE cannot deactivate
the engine immobiliser, the Yand
Uwarning lights stay on and the en-
gine will not start. Follow the emer-
gency start-up procedure to start the
engine.
Read the whole procedure care-
fully before trying to carry it out.
If you make a mistake, you must turn
the ignition key back to STOPand re-
peat the whole operation from the be-
ginning (step 1).1) Read the 5-figure electronic code
given on the CODE card.
2) Turn the ignition key to MAR.
3)Press and hold down the accel-
erator pedal. Warning light
Uwill
come on for about 8 seconds, and
then go out. At this point release the
accelerator pedal and get ready to
count the flashes of the warning light
U.
4) Count the number of flashes that
corresponds to the first figure of the
code on the CODE card, then press
the accelerator pedal and keep it there
until the warning light
Ucomes on
for four seconds and then goes out;
release the accelerator pedal.
5) Warning light
Uwill start flash-
ing again: after it has flashed the num-
ber of times that corresponds to the
second figure on the CODE card,
press the accelerator pedal and keep
it pressed.
6) Do the same for the remaining fig-
ures on the CODE card.7) Once the final figure has been en-
tered, keep the accelerator pedal
pressed. Warning light
Uwill light up
for four seconds and then go out; re-
lease the accelerator pedal.
8)Warning light
Uwill flash rapid-
ly for about 4 seconds to indicate that
the operation has been completed
correctly.
9) Start the engine by turning the ig-
nition key from MARto AVV.
If, however, the warning light
U
stays on, turn the ignition key to
STOPan repeat the procedure from
step 1).
IMPORTANT After an emergency
start-up, you should contact a Fiat
Dealership otherwise you will have
to repeat the procedure described
each time you want to start the en-
gine.

136IN AN EMERGENCY
JUMP STARTING
If the battery is flat, you can use an-
other battery to start the engine. Its
capacity must be the same or slightly
greater than the flat battery.
Proceed as follows fig. 1:
1) connect positive terminals1and
2 (+sign near terminal) of the two
batteries with a jump lead;
2) with a second lead, connect the
negative terminal 3(– sign near the
terminal) of the auxiliary battery to an
earthing point 4(E) on the engine or
gearbox of the vehicle to be started;IMPORTANTDo not directly
connect the two negative terminals:
sparks could ignite the flammable gas
from the battery. If the other battery
is fitted in a vehicle, prevent acciden-
tal contacts between the metal parts
of the two vehicles.
3) Start the engine.
4)when the engine has been start-
ed, remove the leads reversing the or-
der above.
If the engine fails to start after a few
attempts, do not keep turning the key
but have the vehicle seen at a Fiat
Dealership.
fig. 1
F0D0203m
Under no circumstances
should a battery charger
be used to start the en-
gine: it could damage the elec-
tronic systems and in particular
the ignition and injection control
units.
Do not carry out this pro-
cedure if you lack experi-
ence; if it is not done correctly it
can cause very intense electrical
discharges and the battery might
even explode. The liquid in the bat-
tery is poisonous and corrosive.
Keep it away from the eyes and
skin. You are also advised not to put
naked flames or lighted cigarettes
near the battery and not to cause
sparks: risk of fire and explosion.
WARNING

138IN AN EMERGENCY
1. STOP THE VEHICLE
– Stop the vehicle in a position that
is not dangerous for oncoming traffic
where you can change the wheel safe-
ly. The ground should be flat and ad-
equately firm. If you have to change
the wheel at night, choose a lit area if
possible.
– Turn the engine off and pull up the
handbrake.
– Engage first or reverse gear.
– Alert other drivers that the vehicle
is stationary in compliance with local
regulations: hazard warning lights,
warning triangle, etc.
Any passengers should get out and
wait as far away as possible from the
danger of traffic.
If the road is sloping or bumpy, place
wedges or other suitable material to
prevent the vehicle from moving, un-
der the wheels.2. TAKE OUT THE TOOLS,
JACK AND SPARE WHEEL
The tools are in the cab near the
seats.
Please note:
– the jack weights 4.2 kg;
– the jack requires no adjustments;
– the jack cannot be repaired. If it
breaks it must be replaced with a new
jack;
– no other tool, apart from the ex-
tension and the ratchet wrench shown
in this chapter can be fitted to the jack.
The spare wheel is located under the
rear part of the load bed.
Do not lubricate the bolt
threads before fitting
them back: they could come
loose.
WARNING
Check tyre pressure and
spare wheel pressure regu-
larly. Refer to section “Technical
Specifications”.
WARNING

141IN AN EMERGENCY
GENERAL INSTRUCTIONS
When a light is not working, check
that it has not fused before changing
the bulb.
For the location of the fuses, refer to
“If a fuse blows” in this section.
Before replacing a bulb that does not
work, check that the contacts are not
oxidised.
Burnt-out bulbs must be replaced
with ones of the same type. Light from
bulbs with insufficient power is dim
while those which are too powerful
use too much electricity. Always check
the height of the headlight beam after
changing a bulb. Only touch the metal
part when handling halo-
gen bulbs. If the transpar-
ent bulb is touched it reduces the
intensity of the light emitted and
can also reduce the life of the
bulb. If you touch the bulb acci-
dentally, rub it with a cloth
moistened with alcohol and leave
it to dry.IF A BULB
BURNS OUT
Modifications or repairs to
the electrical system car-
ried out incorrectly and without
bearing the features of the system
in mind can cause malfunctions
with the risk of fire.
WARNING
You should have the bulbs
replaced at a Fiat Dealer-
ship, if possible. Correct operation
and proper beam height are essen-
tial for safe driving and compliance
with law requirements.
WARNING
Halogen bulbs contain
pressurised gas which, if
broken, may cause small fragments
of glass to be projected outwards.
WARNING
IMPORTANTOn the inside sur-
face of the headlight there could ap-
pear a slight coat of fogging; this does
not show a defect, since it is a natur-
al occurrence due to low temperature
and to the degree of humidity in the
air; it will disappear as soon as the
lights are turned on. The presence of
drops inside the headlight shows wa-
ter seepage, contact Fiat Dealership.
