Turn knob fig. 83 under the roof to
turn the supplementary climate control
system on. It will only work when the
main system is running.
Air flow is distributed to the back
through the directional vents set under
the roof by lever A-fig. 84.
Like for Panorama and Combi, also the
Van versions can be equipped with an
optional climate control system to be set
in the load compartment and to be
switched on using the relevant console
controls.AIR CONDITIONING
(COOLING)
Control settings for quick cooling:
1)air temperature knob: pointer at
the blue sector
2)climate control system: press but-
ton √
3)air recirculation slider: at Ò
4) air distribution knob: pointer at O
5)fan knob: pointer at the required
speed.To reduce the cooling effect: posi-
tion the slider at Ú, to increase the
temperature and decrease the fan
speed.
Do not switch the climate control
system on for heating and ventilation.
Use the ordinary heating and ventila-
tion system (see previous section).
IMPORTANT The climate control
system is very useful for clearing the
windows rapidly because it dries the
air. Simply set the controls for demist-
ing and turn the climate control sys-
tem on with button √.
ADDITIONAL HEATER
Certain versions feature, under the
driver’s seat, an additional heater us-
ing the same heating system controls.

– 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.

– Always remember to turn the
heater off when refuelling or standing
in service stations to avoid fires and
explosions.
– Do not park the vehicle over in-
flammable material such as paper, dry
grass or leaves: fire risk!
– The temperature near the heater
must never exceed 120°C (e.g. during
painting operations in a workshop
oven). Higher temperatures could
damage the electronic control unit
components.
– When the engine is off, the heater
runs off the battery: it is consequently
important to run the engine for a cer-
tain period of time in order to restore
the battery charge.– Follow the prescriptions in “Vehi-
cle maintenance” section at paragraph
“Engine coolant level” to check the
coolant level. The coolant in the cir-
cuit must contain at least 10% an-
tifreeze fluid.
– Maintenance and repairs must al-
ways be carried out by a Fiat Deal-
ershipand only genuine spare parts
must be used.
MAINTENANCE
Have the heater checked at a Fiat
Dealership periodically (always be-
fore winter). This will ensure safe and
cheap running and long appliance life.
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.

When tilted, the box cover becomes
a writing/reading desk with a clip to
hold sheets/papers, similar to that
shown in fig. 112.
Refrigerator version (food box)
In the refrigerator version, the box
has an internal space of about 12 litres
capacity that can contain 2 one and a
half litre bottles. In this version the
box is insulated and it is fitted with an
electric device to warm up or cool the
box interior as required.
This box can be used as food con-
tainer. Food shall be suitably packed
to avoid direct contact with the inner
walls of the box.
When used for cooling, a tempera-
ture difference of approx. 18 °C can
be achieved between the temperature
inside the box and that of the passen-
ger compartment after a certain time
of operation (with insulated cover and
plug closed). The lowest possible tem-
perature that can be reached in any
case is not lower than 8 -10 °C.To prevent the risk of running the bat-
tery down, the system is connected via
the ignition key; as a result the box will
only work when the engine is running.
You should remove perishables from
the box if you leave the vehicle parked
for longer than two hours.
For proper operation it is necessary
that ventilation grids (outside the box
and on one of the inside walls) should
not be clogged.
Turn the switch to:
1= to warm (red led on);
2= to cool (green led on).

OBJECT HOLDER/
FOOD BOX
A special (optional) box can be found
in the cab between the driver’s seat
and the passenger’s single seat, avail-
able in two models: object box or
food box fig. 113.
Object holder version
In the object holder version, the box
has an internal space of about 12 litres
capacity suitable to contain a medium
size portable PC. On the outside it has
a document holder pocket, a bottle
holder (for one and a half litre plastic
bottles) and a can or glass holder slot.

Diesel fuel fluidity decreases at low
temperatures due to the paraffin it
contains and can clog up the fuel filter.
To avoid possible problems, fuelling
stations usually sell summer, winter or
arctic (mountain/cold areas) fuel ac-
cording to the period of the year. If refuelling with diesel fuel not suitable
for the temperature of use, add
DIESEL MIXto the fuel, in the pro-
portions written on the container. Pour
the antifreeze into the fuel tank before
the fuel.
DIESEL MIXantifreeze is effective
only if it is added before the cold be-
gins to take effect on the fuel. Adding
the product after will not have any ef-
fect.

If you still cannot start the engine,
get in touch with a Fiat Dealership.
IMPORTANT When the outside
temperature is low, it is important to
note that the use of a more fluid oil
will facilitate starting the cold engine.
Therefore, in winter, follow the advice
in chapter “Technical specifications”,
paragraph “Fluids and lubricants”.
IMPORTANTNever leave the igni-
tion key at MARwhen 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.HOW TO WARM UP
THE ENGINE AFTER IT
HAS JUST STARTED
(petrol and diesel versions)
– Begin to move forward slowly let-
ting the engine turn at medium revs.
Do not accelerate abruptly.
– Do not push the engine to its lim-
it for the first few kilometres. You are
recommended to wait until the
coolant temperature indicator starts
to move.
EMERGENCY START-UP
If the Fiat CODE system fails to
recognise that code transmitted by the
ignition key (warning light Yon the
instrument panel lit) the emergency
start-up can be performed by using the
CODE card code.
See the “In an emergency” section.Catalysed vehicles must
not be bump started
(pushed, towed or coast-
ed downhill) as this could cause
fuel to flow into the catalytic ex-
haust system and damage it be-
yond repair.
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.

SWITCHING OFF
THE ENGINE
Turn the ignition key to STOPwhile
the engine is idling.
IMPORTANTAfter a taxing drive
you should allow the engine to “catch
its breath” before turning it off by let-
ting it idle to allow temperature in the
engine compartment to fall.PARKING
Switch off the engine, pull up the
handbrake and engage a gear (1st gear
or reverse, according to whether the
vehicle is facing up or downhill) and
leave the wheels turned. If the vehi-
cle is left on a steep slope, wedges or
a rock should be used to lock the
wheels.
Do not leave the ignition key at
MAR to prevent running the battery
down. Always remove the key when
you leave the vehicle.HANDBRAKE
The handbrake lever is located on
the left-hand side of the driver’s seat.
Pull the lever upwards as far as it will
go to apply the handbrake. Instrument
panel warning light xwill come on
when the key is turned to MAR.
IMPORTANTThe vehicle must be
blocked after three or four lever re-
leases when the vehicle is empty; the
number of releases necessary to block
it depend on the load and on the road
slope.
In case of problems, contact a Fiat
Dealershipto have it adjusted. A quick burst on the ac-
celerator before turning
off the engine serves ab-
solutely no practical purpose and
wastes fuel. It can also damage
turbo-charged engines.

WARNING

115GETTING THE BEST OUT OF YOUR VEHICLE
Moving the lever back to position D
the gearbox instantly resumes the au-
tomatic mode selecting the ratio ac-
cording to the driving characteristics.
IMPORTANTThe electronic con-
trol unit is programmed to change
gear one at a time, therefore repeat-
ed fast actuations will not result in re-
peated engagements of the gears. The
higher or lower gear is engaged mov-
ing the lever to the (+) or (–) position
when the previous request has been
performed.
In the event of a fault to the sequen-
tial manual system, the system will se-
lect the automatic mode.FAILURE INDICATIONS
Automatic gearbox faults are indi-
cated by the warning light A-fig. 9 on
the instrument panel.
Turning the ignition key to MARthe
warning light should turn on and go
out after about 4 seconds. If the warn-
ing light stays on or if turns on when
travelling, this indicates a gearbox fault
(flashing light) or gearbox oil over-
heating (steadily glowing light).– Warning light glowing steadi-
ly= automatic gearbox oil maximum
temperature.
If the warning light turns on and
glows steadily when travelling, this in-
dicates that the gearbox oil has
reached the maximum temperature.
You are therefore advised to stop the
vehicle with the engine at idle speed
and gearshift lever in “N” or “P” (in
this case engine cooling fans are on),
until the warning light goes out and re-
sume your journey without pushing
the engine to peak performance.
If the warning light turns on again, it
is necessary to stop again with the en-
gine idling until it goes out.
If there are less than 15 minutes be-
tween one turning on of the warning
light and the next, you are advised to
stop the vehicle, do not switch off the
engine but allow the engine-gearbox
unit to cool down completely (both
engine cooling fans 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.
