SELF-STANDING SUPPLEMENTARY
HEATER (where provided)
The vehicle can be equipped, upon re-
quest, with two different self-standing
heaters:one is totally automatic
whereas the other is programmable.
AUTOMATIC VERSION
The supplementary heater is totally in-
dependent from the engine.
This heater is switched on automat-
ically (if required) when turning the ig-
nition key to MAR. LOOKING AFTER THE
SYSTEM
During the winter, the climate con-
trol system must be turned on at least
once a month for about ten minutes.
Before summer, have the system
checked at a Fiat Dealership.PROGRAMMABLE VERSION
The supplementary heater is totally
independent from the engine and can
be used to:
– heat the passenger compartment
when the engine is off;
– defrost the windows;
– heat the engine coolant and con-
sequently the engine before starting.
The system consists of:
– a diesel burner to heat coolant with
exhaust fume muffler;
– a metering pump connected to the
vehicle fuel pipes to feed the burner;
– a heat exchanger connected to the
engine cooling system pipes; The system is filled with
R134a refrigerant which
will not pollute the envi-
ronment in the event of leakage.
Under no circumstances should
R12 fluid be used as it is incom-
patible with the system compo-
nents and contains CFC.
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.

– 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.

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.

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).
