SUPPLEMENTARY HEATER
INDEPENDENT
(for markets/versions, where provided)
The vehicle is available, on request, with two different
independent heaters: one fully automatic, the other
which can be programmed.
AUTOMATIC VERSION
The additional heater is turned on in automatic mode
when the engine is started and the required outside
temperature and coolant conditions are present.
Deactivation is always automatic.
IMPORTANT During periods with low outdoor
temperatures when the device cuts in, check that the
fuel level is always higher than the reserve level.
Otherwise the device could lock and require the
assistance of a Fiat Dealership.
The heater burns fuel in the same way
as the engine, though to a lesser extent.
To prevent poisoning and asphyxiation, the
supplementary heater must never be turned on,
even for short periods, in closed environments
such as a garage or workshops without
extraction fans for the exhaust gases.
WARNING
PROGRAMMABLE VERSION
The additional heater operates completely
independently of engine operation and allows the
following:
❒heating the vehicle passenger compartment with the
engine off;
❒defrosting the windows;
❒heating the engine coolant and consequently the
engine itself prior to starting.
The system consists of:
❒a diesel burner to heat the water with an exhaust
silencer for the combustion gases;
❒a metering pump connected to the vehicle tank
pipes, to supply the burner;
❒a heat exchanger connected to the engine cooling
system pipes;
❒a control unit connected to the passenger
compartment heating/ventilation system to allow
automatic operation;
❒an electronic control unit for control and operation
of the burner in the heater;
❒a digital timer A-fig. 55 for turning the heater on
manually or programming the time it comes on.

around two minutes to dissipate as much heat as
possible from the heater; the heater can be turned back
on during this stage.
The heater burns fuel in the same way
as the engine, though to a lesser extent.
To prevent poisoning and asphyxiation, the
supplementary heater must never be turned on,
even for short periods, in closed environments
such as a garage or workshops without
extraction fans for the exhaust gases.

IMPORTANT Before switching the device on, check
that the fuel level is higher than the reserve level.
Otherwise the device could lock and require the
assistance of a Fiat Dealership.
❒Always turn off the heater when refuelling and near
service stations to avoid the risk of explosion or fire
hazards.
❒Do not park the vehicle on inflammable material
such as paper, grass or dry leaves: fire hazard!
❒The temperature near the heater should not exceed
120 °C (e.g. during stove painting in a body shop).
The electronic control unit components may be
damaged at higher temperatures.
❒Whilst the heater is operating with the engine
switched off, it absorbs energy from the battery; the
engine should therefore be left running for a while to
make sure that the battery is properly recharged.
❒To check the coolant level, follow the instructions in
the “Vehicle maintenance” chapter in the “Engine
coolant system fluid” paragraph. The water in the
heating circuit must contain a minimum percentage
of 10% antifreeze.
❒For maintenance and repairs, only contact Fiat
Dealerships and only use genuine spare parts.
F0N0233mfig. 61
MAINTENANCE
Have the additional heater checked regularly at a Fiat
Dealership (and always at the start of every winter).
This will guarantee safe and economic operation of the
heater as well as a long duration.
ADDITIONAL REAR HEATING
(Panorama and Combi)
(for versions/markets, where provided)
The Panorama and Combi versions have a main heating
system plus an additional one (on request) with the

ELECTRICAL POWER SUPPLY AND
FUEL CUT OFF SWITCH
The vehicle is fitted with a safety switch that, in the
event of a crash, comes into operation by cutting off the
fuel supply and turning off the engine as a consequence.
When the inertia switch cuts in, this cuts off the fuel
supply and also activates the hazard warning lights, side
lights and courtesy lights while releasing all the doors
and displaying a message; they are deactivated by
pressing button A. An additional safety switch is also
present that is activated in the event of impact to cut off
the electrical supply. In this way, fuel is prevented from
escaping if the pipes are broken as well as the formation
of sparks or electrical discharges following damage to
the vehicle electrical components.
IMPORTANT After an accident, remember to remove
the key from the ignition device to avoid draining the
battery.
If no fuel leaks or damage to vehicle electrical
devices (e.g. headlights) are detected after the impact and the
vehicle is able to set off again, reactivate the automatic fuel
cut off and electrical supply switches (
for versions/markets
where provided)
following the procedure described below.
If, after a crash, you smell fuel or see
leaks from the fuel system, do not reset
the switches to avoid the risk of fire.
WARNING
Reactivating the fuel cut-off switch fig. 85
Press the button A to reactivate the fuel cut off switch.

REFUELLING THE VEHICLE
OPERATION AT LOW TEMPERATURES
If the outside temperature is very low, diesel thickens
due to the formation of paraffin clots with consequent
defective operation of the fuel supply system.
In order to avoid these problems, different types of
diesel are distributed according to the season: summer
type, winter type and arctic type (cold/mountain areas).
If refuelling with diesel fuel whose specifications are not
suitable for the current temperature, it is advisable to
mix TUTELA DIESEL ART additive in the proportions
shown on the container with the fuel. Pour the additive
into the tank before the diesel fuel.
When using or parking the vehicle for a long time in the
mountains or cold areas, it is advisable to refuel using
locally available diesel fuel.
In this situation it is also advisable to keep the fuel tank
more than 50% full. PREPARATION FOR TELEPASS DEVICE
IN REFLECTIVE WINDSCREEN
(for versions/markets where provided)
If the vehicle is equipped with a reflective windscreen,
install the Telepass in the appropriate area shown in
fig. 134-135.

The hermetic seal may cause a slight increase in
pressure in the tank. A little breathing off, while
slackening the cap is absolutely normal.
When refuelling, attach the cap to the device inside
the flap as shown in fig. 136.
REFUELLING CAPACITY
To fill the tank completely, top-up twice after the first
click of the fuel delivery gun. Further top-ups could
cause faults in the fuel feeding system.
FUEL TANK CAP fig. 136
When refuelling, open the flap A then undo the cap B
turning the ignition key anticlockwise; the cap has
a device C to prevent it being lost.Only use diesel fuel that conforms to
European specification EN590. The use
of other products or mixtures may
damage the engine beyond repair and
consequently invalidate the warranty, due to
the damage caused. If you accidentally introduce
other types of fuel into the tank, do not start the
engine and empty the tank. If the engine has run,
even for a very short time, you will need to have
the entire fuel system emptied in addition to
the tank.
Do not bring naked flames or lit
cigarettes near to the fuel tank opening:
fire risk. Keep your face away from the fuel
filler to avoid breathing in harmful vapours.

DIESEL PARTICULATE FILTER (DPF)
The Diesel Particulate Filter is a mechanical filter,
integral with the exhaust system, that physically traps
particulates present in the exhaust gases of diesel
engines.
The diesel particulate filter has been adopted to
eliminate almost all particulates in compliance with
current/future legal regulations.
During normal use of the vehicle, the engine
management control unit records a set of data (travel
time, type of route, temperatures, etc.) and it will
then calculate how much particulate has been trapped
by the filter.
Since this filter physically traps particulate, it should be
regenerated (cleaned) at regular intervals by burning
carbon particles.
The regeneration procedure is controlled automatically
by the engine management control unit according to the
filter conditions and vehicle use conditions.
There may be a limited increase in the engine idle speed
during the regeneration, a limited increase in fumes and
high temperatures at the exhaust. These are not faults;
they do not impair vehicle performance or damage the
environment.
If the dedicated message is displayed, refer to the
“Warning lights and messages” section.PROTECTING THE ENVIRONMENT
The following devices are used for reducing diesel fuel
engine emissions:
❒oxidising catalytic converter;
❒exhaust gas recirculation system (E.G.R.);
❒diesel particulate filter (DPF).
The diesel particulate filter (DPF)
reaches high temperatures during
operation. Therefore do not therefore park the
vehicle on inflammable materials (grass, dry
leaves, pine needles, etc.): fire hazard.
WARNING
The catalytic converter also reaches
high temperatures during normal
operation. Do not park the car on grass, dry
leaves, pine needles or other flammable
material: fire hazard.
