LPG tank certification
The LPG tank is certified in accordance
with the regulations in force.
In Italy, the tank has a life of 10 years
starting from the vehicle registration
date. If the vehicle has been registered
in a country other than Italy, the
duration and the testing/inspection
procedures of the LPG tank can vary
depending on the national laws of that
country. In any case, when the time limit
in the individual country has run out,
contact a Fiat Dealership to have the
tank replaced.
SELECTION OF
PETROL/LPG SUPPLY
TYPE
35)14) 15) 16)
The (petrol/LPG switch) button A fig. 39
allows drivers to select petrol or LPG
operation.To guarantee switching in absolute
safety, the actual change to the chosen
fuel system takes place depending on
the car usage conditions. It may not
therefore be immediate.
Switching is confirmed by the switching
on/off of the green warning light
on
the instrument panel.
If the LPG runs out, switching to petrol
takes place automatically. In this case
the display shows the
icon just
above wording LPG and the four bars
of the digital gauge turn off.

LPG
Maximum refuelling capacity (reserve
included): 30.5 litres. The figure already
takes into account the 80% tank filling
limit and the residual fluid required
for correct priming and it is the
maximum permitted capacity. In
addition, after different refuelling
processes, this figure may vary due to
differences between the network pump
supply pressures, pumps having
different supply/locking features, tank
not completely run out of fuel.
WARNING
33)It should be pointed out that in some
countries (including Italy) there are legal
restrictions in force for parking/garaging
motor vehicles with gas that has a higher
density than air; LPG comes under this
category.
34)Modifications or repairs to the fuel
system that are not carried out correctly or
do not take the system technical
specifications into account can cause
malfunctions leading to a fire risk.
35)Do not switch between the two
operating modes whilst starting the engine.
WARNING
9)The system operates at temperatures
ranging between −20 °C and 100 °C.
10)If, during LPG operation, the same runs
out, the vehicle switches to petrol
automatically and all the bars of the digital
gauge on the display switch off; this
displaying remains until the following LPG
refuelling.

The methane, stored in the cylinders at
high pressure, flows through a
dedicated pipe to reach the pressure
regulator/reduction unit which supplies
the two methane injectors at low
pressure (about 9 bar).
Cylinder certification
The methane cylinders are certified in
accordance with ECE Regulation
110.
The cylinders must be inspected, in
accordance with ECE Regulation
Procedure no. 110, every 4 years from
the vehicle registration date or in
accordance with specific regulations in
individual countries.
The plates provided by the Dealership
with the on board documentation
contain the date for the first inspection
of the cylinders. Methane refuelling
stations are not authorised to refill the
cylinders when the inspection date has
expired.IMPORTANT If the vehicle has been
registered in a country other than Italy,
the certification data, identification
and inspection procedures for
the methane cylinders should conform
to the legislation in that country. In
any case, remember that the life of the
cylinders is 20 years from the
production date as set out in ECE
Regulation no. 110.
SELECTION OF
PETROL/METHANE
SUPPLY TYPE
39)20) 21) 22)
This engine normally runs on methane
except during starting, when it runs
on petrol.
The (petrol/methane switch) button A
fig. 42 allows drivers to select petrol or
methane operation.To guarantee switching in full safety, the
actual change to the chosen fuel
system takes place depending on the
car usage conditions; it may not
therefore be immediate.
Switching is confirmed by the switching
on/off of the green warning light
on
the instrument panel.
In addition, when starting at outside
temperatures below approximately
–10°C, the switching times from petrol
to methane increase to allow the
pressure regulator/reduction unit to
heat up.
If the methane has run out, switching to
petrol takes place automatically. In this
case, the four bars of the digital gauge
switch off and the green warning light
on the instrument panel switches on.
SUPPLIES
Methane
Capacity: about 12 kg. The total
volume of cylinders is about 72 litres.

WARNING
36)The Fiat Panda Natural Power is
equipped with a high pressure methane
fuel supply system, designed to operate at
a rated pressure of 200 bar. It is dangerous
to stretch the system with higher
pressures. To prevent damage to the
methane system parts when towing or
raising the vehicle, follow the instructions in
the "Towing the vehicle" paragraph of the
Owner Handbook. If there is a problem
with the methane system, only contact a
Fiat Dealership. Do not alter the methane
system configuration or components; they
are designed exclusively for the Fiat Panda
Natural Power. The use of other
components or materials could cause
malfunctions and reduce safety.
37)In the case of painting in an oven, the
cylinders should be removed from the
vehicle and refitted later by a Fiat Dealer.
Although the methane system has
numerous safety features, it is advisable to
close the manual cocks for the cylinders
every time the vehicle is not in use for
a long period, transported on other
vehicles or moved in an emergency as a
result of a breakdown or accident.
38)Modifications or repairs to the fuel
system that are not carried out correctly or
do not take the system technical
specifications into account can cause
malfunctions leading to a fire risk.
39)Do not switch between the two
operating modes whilst starting the engine.
WARNING
19)If, during methane operation, the same
runs out, the vehicle switches to petrol
automatically and all the bars of the digital
gauge on the display switch off; this
displaying remains until the next methane
refuelling.
20)Regardless of the last fuel system
used, at the following engine starting, after
the initial petrol stage, the system will
automatically switch to methane.
21)When switching from petrol to methane
is requested, a metal noise from the valves
which pressurise the circuit can be heard,
as it happens while starting the vehicle.
As a result of the switching logic described
above, the delay between the ticking of
the valve and the switching off of the green
warning light
on the instrument panel
is entirely normal.22)In particular usage conditions, such as
starting and operation at low ambient
temperature, the system may switch
temporarily to petrol operation, without
indicating the performed switching. In the
event of low methane levels in the tank
or request for high performance (e.g.
overtaking, vehicle fully laden, steep hills),
the system may automatically switch to
petrol operation to guarantee the engine
power requested; the green warning light
on the instrument panel switches on
to indicate this. When the above conditions
are no longer present, the system
automatically restores methane operation;
the green warning light
switches off.
To achieve the automatic switching
described above, make sure that there is
always enough fuel in the petrol tank.

GETTING TO KNOW YOUR CAR

Warning light What it means
Parking sensor failure
(for versions/markets, where provided)
The warning light switches on, on some versions along with a dedicated message on the display, when a
fault is detected in the parking sensors.
Exterior light failure
(for versions/markets, where provided)
The warning light switches on when a fault is detected in one of the following lights: side lights, number
plate lights, rear fog lights, direction indicators, daytime running lights (DRL).
Engine oil pressure sensor failure
(for versions/markets, where provided)
The engine oil pressure sensor failure is indicated by the activation of the warning light on the instrument
panel.
ELD system fault(Panda Cross and Panda 4x4 versions)
The warning light switches on, on some versions along with a dedicated message on the display, when a
fault is detected in the 4x4 drive. Contact a Fiat Dealership as soon as possible.
Water in diesel filter(diesel versions)
(for versions/markets, where provided)
When the key is turned to MAR, the warning light switches on but it should switch off after a few seconds.
The warning light switches on when water is detected in the diesel filter. On certain versions a dedicated
message is displayed.
25)
WARNING
25)If thewarning light switches on (on some versions together with the dedicated message on the display), contact a Fiat Dealership as
soon as possible to have the system bled. If this problem is indicated immediately after refuelling, water may have entered the fuel tank. In
this case, immediately turn off the engine and contact a Fiat Dealership.
54
KNOWING THE INSTRUMENT PANEL

Warning light What it means
iTPMS
(for versions/markets, where provided)
Tyre pressure low
The warning light switches on constantly to indicate that the tyre pressure is lower than the recommended
value, in order to guarantee long tyre life and low fuel consumption, or to indicate a slow loss of pressure.
In this way the iTPMS warns the driver that one or more tyres may be flat and probably punctured. In this
case it is advisable to restore the correct pressure value. Once the normal operating conditions of the
vehicle are restored, carry out the Tyre reset procedure.
IMPORTANT Do not continue driving with one or more flat tyres as handling may be compromised. Stop
the vehicle, avoiding sharp braking and steering.
iTPMS failure/iTPMS temporarily deactivated
The warning light flashes for about 75 seconds and then stays on constantly (along with a dedicated
message on the display) to indicate that the system is temporarily deactivated or faulty. The system goes
back to normal operation when the operating conditions allow it. If this is not the case, carry out the Tyre
reset procedure after restoring the normal operating conditions.
If the malfunction warning persists, contact a Fiat Dealership as soon as possible.
LPG FUEL RESERVE
(for versions/markets, where provided)
The warning light switches on when the residual quantity of LPG in the cylinder goes below 1/5 of the
capacity. On some versions a dedicated message is displayed.
METHANE RESERVE (Natural Power versions)
The warning light switches on when the residual quantity of methane in the cylinder goes below 1/5 of the
capacity. On some versions a dedicated message is displayed.

74)If the vehicle must be placed on a roller
bench (at a speed within 5 and 30 km/h)
for maintenance interventions or if it is
washed in an automatic roller washing
tunnel with an obstacle in the front part
(e.g. another vehicle, a wall or another
obstacle), the system may detect its
presence and activate. In this case the
system must be deactivated through the
display Setup Menu.
75)If the system signals a pressure
decrease on a specific tyre, it is
recommended to check the pressure on all
four tyres.
76)iTPMS does not relieve the driver from
the obligation to check the tyre pressure
every month; it is not even to be
considered a replacing system for
maintenance or a safety system.
77)Tyre pressure must be checked with
tyres cold. Should it become necessary for
whatever reason to check pressure with
warm tyres, do not reduce pressure even
though it is higher than the prescribed
value, but repeat the check when tyres are
cold.
78)The iTPMS cannot indicate sudden
tyre pressure drops (for example when
a tyre bursts). In this case, stop the vehicle,
braking with caution and avoiding abrupt
steering.
79)The system only warns that the tyre
pressure is low: it is not able to inflate
them.
80)Insufficient tyre inflation increases fuel
consumption, reduces the tread duration
and may affect the capacity to drive safely.
WARNING
28)The laser sensor may have limited or
absent operation due to weather
conditions such as: heavy rain, hail, thick
fog, heavy snow, formation of ice layers on
the windscreen.
29)Sensor operation may also be
compromised by the presence of dust,
condensation, dirt or ice on the
windscreen, by traffic conditions (e.g.
vehicles that are driving not aligned with
yours, vehicle driving in a transverse or
opposite way on the same lane, bend with
a small radius of curvature), by road
surface conditions and by driving
conditions (e.g. off-road driving). Make sure
the windscreen is always clean. Use
specific detergents and clean cloths to
avoid scratching the windscreen. The
sensor operation may also be limited or
absent in some driving, traffic and road
surface conditions.
30)Projecting loads on the roof of the
vehicle may interfere with the correct
operation of the sensor. Before starting
make sure the load is correctly positioned,
in order not to cover the sensor operating
range.
31)If the windscreen must be replaced
due to scratches, chipping or breakage,
contact exclusively a Fiat Dealership.
Do not replace the windscreen on your
own, risk of malfunction! It is advisable to
replace the windscreen if it is damaged
in the laser sensor area.32)Do not tamper nor operate on the laser
sensor. Do not close the openings in the
aesthetic cover located under the interior
rear view mirror. In the event of a sensor
failure, contact a Fiat Dealership.
33)Do not cover the operating range of the
sensor with stickers or other objects. Also
pay attention to other objects on the
bonnet (e.g. a layer of snow) and make
sure they do not interfere with the light
emitted by the laser.
34)If a trailer or a vehicle is towed the
system must be deactivated with the
display Setup Menu.
70
SAFETY

132)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 prevent breathing in harmful
vapours.
133)Do not use a mobile phone near the
refuelling pump: risk of fire.
WARNING
46)The vehicle must only be filled with
diesel fuel for motor vehicles, in
compliance with European Standard EN
590. 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 refuel with another type of fuel,
do not start the engine, and drain the
tank. If the engine has run, even for a very
short time, you will need to have the entire
fuel supply system emptied in addition to
the tank.
47)The other plates (provided with the
vehicle documents) show the date when
the first cylinder inspection/test is due.
Methane refuelling stations are not
authorised to refill the cylinders when the
inspection date has expired.
100
STARTING AND DRIVING
WARNING
131)Do not apply any object/cap to the
end of the filler which is not provided
for the vehicle. The use of non-compliant
objects/caps could cause a pressure
increase inside the tank, resulting in
dangerous situations.

SCHEDULED
SERVICING
Correct servicing is crucial for
guaranteeing a long life for the vehicle
under the best conditions. For this
reason, Fiat has planned a series of
checks and services at fixed distance
intervals and, where provided, at fixed
time intervals, as described in the
Scheduled Servicing Plan.
Before each service, it is always
necessary to carefully follow the
instructions in the Scheduled Servicing
Plan (e.g. periodically check level of
fluids, tyre pressure, etc.).
Scheduled Servicing is offered by all
Fiat Dealerships according to a set time
schedule. If, during each operation, in
addition to the ones scheduled, the
need arises for further replacements or
repairs, these may be carried out with
your explicit agreement only. If your
vehicle is used frequently for towing,
the interval between one service
operation and the next should be
reduced.IMPORTANT Scheduled Servicing
interventions are set out by the
Manufacturer. Failure to have them
carried out may invalidate the warranty.
It is advisable to inform a Fiat
Dealership of any small operating
irregularities without waiting for the next
service.
PERIODIC CHECKS
Every1,000km or before long
journeys, check and if necessary, top
up: engine coolant level; brake fluid
level; screen washer fluid level; tyre
inflation pressure and condition; lighting
system operation (headlights, direction
indicators, hazard warning lights, etc.);
screen washer/wiper system operation
and positioning/wear of windscreen/
rear window wiper blades.
Every3,000km, check and top up if
required: engine oil level.HEAVY-DUTY USE OF THE
VEHICLE
If the vehicle is used under one of the
following conditions: towing a trailer
or motorhome; dusty roads; short (less
than 7-8 km) and repeated journeys
with sub-zero outside temperatures;
engine often idling or driving long
distances at low speed or long periods
of inactivity, the following checks must
be carried out more often than
indicated in the Scheduled Servicing
Plan:
❒check front disc brake pad condition
and wear;
❒check cleanliness of bonnet and
luggage compartment locks,
cleanliness and lubrication of linkage;
❒visually inspect conditions of: engine,
gearbox, transmission, pipes and
hoses (exhaust/fuel system/brakes) and
rubber elements (gaiters/sleeves/
bushes, etc.);
❒check battery charge and battery
fluid level (electrolyte);
❒visually inspect conditions of the
auxiliary drive belts;
❒check and, if necessary, change
engine oil and replace oil filter / pollen
filter / air cleaner.
