CONSTRUCTION FEATURES
DUCATO automatic gearbox is con-
trolled electronically with four for-
ward gears and reverse.
It is controlled by an electronic con-
trol unit which handles:
– the torque distributor;
– gearshifting;
– specific programmes.
The gearbox is coupled with a flow
power torque distributor with piloted
antislip device which makes it possible
to obtain demultiplication ratios.
The characteristic of this gearbox
which works without idle gear enables:
– higher compactness and weight re-
duction;
– improved output due to less fric-
tion;
– lower stress of transmission com-
ponents.GENERAL FEATURES
Electronic gearbox control makes it
possible to obtain gearshifting suited
to momentary engine characteristics
with a certain elasticity.
The electronic control unit has the
following task:
– adapting the oil pressure for
gearshifting to the engine torque;
– activating safety functions;
– defining the manual gearshifting
programme;
– system diagnostics.
For controlling these operating log-
ics the control unit uses the follow-
ing signals:
– engine rpm;
– engine temperature;
– engine torque;
– vehicle speed;
– gearbox oil temperature;– gearshift lever position;
– accelerator pedal position;
– brake pedal position.
The control unit also communicates
with the injection system electronic
control unit.
Conditions of use analysed by
the control unit
The control unit analyses each single
condition of use of the vehicle, dis-
criminating it on the basis of the sig-
nals received from the various sensors.
Analysed conditions are the follow-
ing:
– starting (position/accelerator ped-
al changing speed);
– acceleration (accelerator pedal
completely pushing down speed);
– full load (number of engine full load
kickdown signals or position mainte-
nance time);

118GETTING THE BEST OUT OF YOUR VEHICLE
– braking (accelerator pedal release
time and braking system operation);
– type of programme (gearshift se-
lector lever position);
– winter driving (driving wheel
torque reduction);
– driving with trailer or uphill (vehi-
cle speed in relation to transmitted
torque)
– driving downhill (vehicle accelera-
tion in relation to the position of the
accelerator pedal);
– driving in towns or queues (accel-
erator pedal position and vehicle
speed);
– gear required by the driver
(gearshift lever position);
– cold starting (engine temperature).Gearshift programme control
To optimise vehicle handling the
electronic control unit has the fol-
lowing memorised programmes:
– automatic operation;
– manual operation;
– winter driving (to be selected
through buttonWINTER);
– engine warming up;
– protection against excessive gear-
box oil temperature .Automatic programme
This comprises 16 gearshifting pro-
grammes.
In relation to the vehicle speed and
torque transmitted, the control unit
detects the slope of the road surface
and depending on the sporty features
chosen, it autonomously chooses the
programme most suited to the situa-
tion.
During gearshifting, the gearbox con-
trol unit asks the injection control unit
to momentarily reduce the torque.
The duration of torque reduction
varies depending on the travelling con-
ditions.

Manual sequential programme
This function enables manual se-
quential use of the gearbox merely
moving the selector lever to the left.
Each time the lever is pressed only
one gear is shifted: more than one shift
cannot be obtained.
To avoid overevving or excessively
low engine rpm, the control unit in-
hibits requests for gearshifting that
would cause such situations.
Winter driving programme
This programme is engaged by press-
ing button WINTERnear the
gearshift lever,
in case of driving wheel skidding and
it changes to specific gears.
Starting is possible only in 2
ndgear.
On snowy roads use however snow
chains and/or tyres.
The WINTERfunction shall always
be off on slopes.Engine warming up programme
This programme allows the engine to
reach normal operating temperature
in the shortest time possible (de-
pending on the outside temperature)
highering the gearshifting points, in re-
lation to engine temperature.
The programme engages automati-
cally after starting, if the engine tem-
perature is below 30 °C and it remains
active up to 34 °C.
Excessive gearbox oil
temperature programme
This is activated when the gearbox
oil temperature reaches 120 °C and it
remains active down to 117 °C.
To facilitate oil cooling, this pro-
gramme inhibits gearshifting, either up
or down. It is however possible to use
the manual programme.
SAFE DRIVING
In designing Ducato, Fiat has made
every effort to come up with a vehicle
able to provide driver and passengers
with top-class levels of safety. Never-
theless it is always the behaviour of the
person at the wheel that determines
road safety.
In the following pages you will find
some simple tips to help you travel in
safety under different conditions. You
will no doubt be familiar with many of
them already but it will be useful to
read them all carefully.

Electric devices
Use electric devices for the neces-
sary time only. The heated rear win-
dow, fog lights, windscreen wipers,
heater fan require large amounts of
electricity and increasing the request
for power will also increase fuel con-
sumption (up to +25% when driving in
towns).
Climate control system
The climate control system is an ad-
ditional load which greatly affects the
engine leading to higher consumption.
When the temperature outside the
vehicle allows it, use the air vents
where possible.
DRIVING STYLE
Starting
Do not warm the engine when the
vehicle is stationary or at high or low
speed: in this way the engine will warm
up gradually increasing consumption
and emissions. You should drive off
slowly straight away avoiding high revs
so that the engine will warm up more
quickly.Unnecessary actions
Avoid revving the engine when
stopped at traffic lights or before
switching off the engine and avoid dou-
bling the clutch as these actions have
no purpose on modern vehicles and
serve only to increase consumption
and pollution.
Gear selections
As soon as the traffic and road con-
ditions allow it, shift to a higher gear.
Using a low gear to liven up accelera-
tion greatly increases consumption. In
the same way improper use of high
gears will increase consumption, emis-
sions and engine wear.
On passenger transportation versions
fitted with 2.3, 2.8 JTD and 2.8 JTD
POWER engines, fuel consumption can
be optimised by starting (on level road)
in 2nd gear instead of 1st gear.Top speeds
Fuel consumption increases consid-
erably as speed increases. Your speed
should be kept as even as possible and
superfluous braking and acceleration
avoided as this increases both con-
sumption and emissions.
Acceleration
Accelerating violently increasing the
revs will greatly affect consumption
and emissions; acceleration should be
gradual and should not exceed the
maximum torque.

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.

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

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.

General instructions
Observe the instruc-
tions on this and the fol-
lowing pages to use the
jack and spare wheel correctly.Catalysed vehicles must
not be bump started
(pushed, towed or
coasted downhill) as this could
cause fuel to flow into the cat-
alytic exhaust system and dam-
age it beyond repair.
Never start the engine
when the vehicle is jacked
up.
WARNING
Remember that until the
engine has started the
brake booster and power steering
systems will not work and a greater
effort will therefore be required to
depress the brake pedal or turn the
steering wheel.
WARNING
If you are towing a trailer,
remove the trailer before
jacking up the vehicle.
WARNING
The jack should only be
used to changed a wheel on
the vehicle for which it was de-
signed. It should not be put to oth-
er uses or employed to raise other
models. Under no circumstances
should it be used when carrying out
repairs under the vehicle. An incor-
rectly positioned jack may cause
the vehicle to fall. Do not use the
jack to lift loads exceeding that in-
dicated on the label attached to the
to the jack itself.
