FAILURE CONTROL
SYSTEM
(petrol versions only) (amber)
In normal conditions, the warning
light will come on when the ignition
key is turned to MARand should go
out as soon as the engine is started.
The initial lighting up shows that the
warning light is working properly.
If the warning light either stays on or
comes on while travelling:
1. Fixed light- warning of a fuel
feed/ignition system failure which may
increase emissions in exhaust or cause
possible drops in performance, poor
handling and high consumption.
In such conditions, you can contin-
ue driving but you should not tax the
engine and you should moderate the
speed. Prolonged use with the warn-
ing light on can cause damage. Contact
a Fiat Dealershipas soon as possi-
ble. The warning light will go out when
the failure disappears. In any case, the
system will store the error.
2. Flashing- warning that the cata-
lyst can be damaged (see “EOBD sys-
tem” in this chapter).
If the warning light starts flashing, re-
lease the accelerator pedal and slow
the engine until the warning light stops
flashing. Continue driving at moderate
speed, preventing the warning light
from coming on again. Contact a Fi-
at Dealership as soon as possible.INJECTION SYSTEM
FAILURE
(diesel versions) (red)
When there is a fault in the injection
system.
The warning light should come on
when the ignition key is turned to
MARand go out after a few seconds.
The warning light will stay on or come
on when travelling to indicate imperfect
operation of the injection system with
possible loss of performance, poor han-
dling and higher consumption.
In these conditions, you can contin-
ue driving but you should avoid de-
manding efforts from the engine or
high speeds. Contact a Fiat Dealer-
shipas soon as possible.
Prolonged use of the vehicle with the
warning light on can cause damage to
the engine, especially in the event of
misfiring. The vehicle can only be dri-
ven for a short period of time at low
speeds.
Occasional and brief lighting of the
warning light is meaningless.

Contact a Fiat Dealer-
ship as soon as possible if
the
Uwarning light ei-
ther does not come on when the
key is turned to MAR or comes
on, with fixed light or flashing
light, when travelling. Warning

IMPORTANTThe cruise control
can be engaged only with speeds high-
er than 40 km/h.
The device is automatically discon-
nected in one of the following cases:
– pressing the brake pedal;
– pressing the clutch pedal;
– inadvertently moving the automat-
ic gearbox selector to N. A special horn warns any people near
the vehicle that the driver is manoeu-
vring it.
Through four sensors located in the
bumper, the system detects the dis-
tance between the vehicle and possi-
ble obstacles; the driver is warned by
an intermittent acoustic signal with in-
creasing frequency, which is automat-
ically activated when the reverse gear
is engaged.CRUISE CONTROL
GENERAL FEATURES
The cruise control, with electronic
control, allows driving the vehicle at
a desired speed, without pressing the
accelerator pedal. This allows reduc-
ing the driving fatigue on motorways,
especially during long journeys, be-
cause the memorised speed is auto-
matically maintained.
Never set gear selector to
N (vehicles fitted with au-
tomatic gearbox) when the vehicle
is moving.
WARNING
The Cruise Control must be
activated only when the
traffic and the path allow keeping,
for a distance long enough, a con-
stant speed in complete safety.

CONTROLS fig. 100
The cruise control is controlled by
a set of controls located on the steer-
ing wheel.
1) ONdevice on
2) OFFdevice off
3) RESto reset the memorised
speed
4) +to store and to keep the vehicle
speed or to increase the speed memo-
rised
5) – to lower the speed memorised.
IMPORTANTPressing button
OFFor turning the key to STOP,
the memorised speed is cancelled and
the system disengaged.IMPORTANTIn the case of need
(when overtaking for instance) accel-
eration is possible simply pressing the
accelerator pedal; later, releasing the
accelerator pedal, the vehicle will re-
turn to the speed memorised previ-
ously.
To reset the memorised speed
If the device has been disengaged for
example pressing the brake or clutch
pedal, the memorised speed can be re-
set as follows:
– accelerate gradually until reaching
a speed approaching the one memo-
rised;
– engage the gear selected at the
time of speed memorising (4
thor 5th
speed);
– press button RES. To memorise the speed
Press button ONand take the ve-
hicle to the required speed normally.
Press button +for at least three sec-
onds, then release it. The vehicle
speed is memorised and it is therefore
possible to release the accelerator
pedal.
The vehicle will carry on its ride at
the constant memorised speed until
one of the following condition occurs:
– pressing the brake pedal;
– pressing the clutch pedal;
– inadvertently moving the automat-
ic gearbox selector to N.

To increase the memorised
speed
The speed memorised can be in-
creased in two ways:
1 -pressing the accelerator and then
memorising the new speed reached
(pressing button + for more than
three seconds);
2 -pressing briefly button +: each
pressing will correspond to a slight in-
crease in speed (about 2.5 km/h) while
pressing continuously will correspond
to a continuous speed increase. Re-
leasing the button the new speed will
be memorised automatically.
To reduce the memorised
speed
The speed memorised can be re-
duced in two ways:
1 -disengaging the device (for in-
stance pressing the brake pedal) and
then memorising the new speed
(pressing button +for more than
three seconds);
2 -pressing button –until reaching
the new speed which will be memo-
rised automatically.To set to zero the memorised
speed
The memorised speed is automati-
cally reset:
– turning the engine off;
– pressing buttonOFF.Do not engage the device in town or
in busy flowing traffic conditions.
When travelling with the
cruise control on, do not
move the gearshift lever to neutral
and to not move the automatic
gearbox selector to N. We suggest
to engage the cruise control only
when the traffic and road condi-
tions allow doing it in complete
safety and so: straight and dry
roads, freeways or motorways,
smooth flowing traffic and even as-
phalt.
WARNING
The cruise control can be en-
gaged only with speeds high-
er than 40 km/h. The device may on-
ly be engaged in 4
thor 5thgear, de-
pending on the speed of the vehicle.
On vehicles with electronic automat-
ic gearbox it can only be engaged
with selector to D, in automatic mode
without then moving the selector
manually, or with 3
rdor 4thgear in se-
quential operation. Travelling down-
hill with the device engaged, the ve-
hicle speed may increase more than
the memorised one, due to the
change in the engine load.

IMPORTANT Do not press the
accelerator until the engine has start-
ed.
1) Ensure that the handbrake is up.
2)Put the gear lever into neutral.
3)Press the clutch pedal down to
the floor without touching the accel-
erator.
4) Turn the ignition key to AVVand
release it as soon as the engine starts.
If the engine does not start at the
first attempt, return the ignition key
to STOP before trying to start the
engine again.
If the warning light Ystays on when
the ignition key is at MAR, turn the
key to STOPand then to MAR; if the
warning light stays on, try with the
other keys provided.
If you are still unable to start the en-
gine, go to a Fiat Dealership.IMPORTANTDo not leave the ig-
nition key at MAR when the engine is
off.
Minibus and School Bus versions:
press the ignition enable button lo-
cated to the left of the steering col-
umn as shown in the specific supple-
ment to this handbook.
Never touch the high volt-
age cables (spark plug ca-
bles) when the engine is running.
WARNING
It is dangerous to let the en-
gine run in a garage of oth-
er closed area. The engine con-
sumes oxygen and gives off carbon
dioxide, carbon monoxide and oth-
er poisonous fumes.
WARNING

110GETTING THE BEST OUT OF YOUR VEHICLE
STARTING
After starting the engine, with the en-
gine idling and keeping the brake ped-
al pressed, move the gearshift lever to
position D. Release the brake pedal
and gradually press the accelerator
pedal.
IMPORTANT Movement of the
lever from position Pis allowed only
with the ignition key at MARand the
button on the lever and the brake ped-
al pressed. STOPPING THE VEHICLE
To stop the vehicle, simply press the
brake pedal regardless of the position
of the gearshift lever.
IMPORTANTRemoving the igni-
tion key is only allowed with the
gearshift lever in position Pand for a
maximum time of 30 seconds from
when the engine is turned off P, when
the door is opened a buzzer will sound
for about 15 seconds to alert the dri-
ver.
In the case of an emergency (faults,
flat battery, etc.) the ignition key can
be removed from the switch fitting a
screwdriver in hole infig. 3set under
the ignition switch and pressing up-
wards Do not attempt to ob-
tain peak performance
until the engine has
reached normal operating tem-
perature.

With the engine idling, also
on a level surface, and the
gearshift lever in position D or R,
the vehicle tends to move if the
brake pedal is not kept pressed.
WARNING
ELECTRONIC
AUTOMATIC
GEARBOX
(2.8 JTD versions
only)
The automatic gearbox fitted on Fi-
at Ducato features four speeds plus
reverse with self-adapting control (i.e.
capable of adapting to the driver’s dri-
ving style), which transmits power
continuously and with very fast elec-
tro-hydraulic gear engagement times.
STARTING THE ENGINE
The engine can be started only with
the gearshift lever in the P or Nposi-
tion.
For safety reasons, it is advisable to
start the engine with the brake pedal
pressed.
IMPORTANTWhen moving off af-
ter starting the engine, do not press
the accelerator pedal before and dur-
ing the movement of the gearshift
lever. This is particularly important
when the engine is cold.

113GETTING THE BEST OUT OF YOUR VEHICLE
N - Neutral
This corresponds to the neutral po-
sition of a standard manual gearbox.
This position is to be used if the ve-
hicle is to be pushed or towed.
With the engine idling and
the gearshift lever at N the
vehicle tends to move by inertia if
it is not on a level surface: keep the
brake pedal pressed when the lever
is at N.
WARNING
D - Forward gear
This is the position to be used when
driving forward normally. The elec-
tronic control unit controls automat-
ic engagement of the 4 gears depend-
ing on the position of the accelerator,
driving speed, engine rpm, longitudinal
and transversal acceleration and the
type of road.
The electronic gearbox can chose
between different operating pro-
grammes, which range between com-
fortable economy driving and sporty
driving coming into operation between
the lowest and the highest speed.
Pressing the accelerator pedal quick-
ly the gearbox will immediately select
the sportier programme to meet the
request for increased performance. To
disengage the function release the ac-
celerator by at least 1/4 of the stroke. In the same way, during braking a
lower gear is engaged to better exploit
the braking action of the engine. If
there is another bend the new ratio
will be engaged already when slowing
down before the bend, this way at the
end of the bend the gearbox will not
have to shift gear to cope with accel-
eration.
Kickdown
To obtain optimum acceleration, for
example when overtaking, the gearbox
will kickdown by two gears simply by
quickly pressing fully home the accel-
erator pedal (in 1/10 of a second).
Engagement of the next longer ratio
will take place when the maximum
rpm limit is reached.
With the engine at idle
speed and the gearshift
lever at D, the vehicle tends to move
also on a level surface: keep the
brake pedal pressed until moving off.

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.
