2018 FIAT PANDA fuel pressure

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 car 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 all
case, when the time limit for your
country has expired, go to a Fiat Dealer
to have the tank replaced.

LPG
Maximum refuelling capacity (including
reserve): 30.5 litres. The figure already
takes into account the 80% tank filling
limit and the residual fluid required
for priming; this figure represents the
maximum permitted capacity. In
addition, this figure may vary from one
refuelling to another due to differences
between the network pump supply
pressures, pumps having different
supply/locking features, tank not
completely run out of fuel.
WARNING
30)Note that in some countries (including
Italy) there are legal restrictions in force
for parking/garaging motor vehicles fuelled
by gas that is denser than air; LPG comes
under this category.
31)Modifications or repairs to the supply
system that are not carried out correctly or
do not take the system technical
specifications into account can cause
malfunctions leading to the risk of fire.
32)Do not switch between the two
operating modes whilst starting the engine.
WARNING
10)The system operates at temperatures
ranging between -20°C and 100°C.
11)If the fuel runs out while running on
LPG, the car switches to petrol
automatically and all the bars of the digital
indicator on the display turn off. The
display remains in this state until the next
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 no.
110.
The cylinders must be inspected, in
accordance with ECE Regulation
Procedure no. 110, every 4 years from
the car 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

This engine normally runs on methane
except during starting, when it runs
on petrol.
The button A fig. 44 (petrol/methane
switch) allows you to select running on
petrol or methane.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 green
warning light
on the instrument panel
turning on/off.
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
turns off and the green warning light
on the instrument panel turns on.

WARNING
33)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 gas
system parts when towing or lifting the
vehicle, follow the instructions in the Owner
Handbook, in the paragraph: “Towing the
vehicle”. If there is a fault in 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
prejudice safety.
34)When oven painting, the cylinders must
be removed from the vehicle and
subsequently refitted by a Fiat Dealership.
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.
35)Modifications or repairs to the supply
system that are not carried out correctly or
do not take the system technical
specifications into account can cause
malfunctions leading to the risk of fire.
36)Do not switch between the two
operating modes whilst starting the engine.
WARNING
20)If the fuel runs out while running on
methane, the car switches to petrol
automatically and all the bars of the digital
indicator on the display turn off. The
display remains in this state until the next
methane refuelling.
21)Regardless of the last fuel system
used, at the following engine starting, after
the initial petrol stage, the system will
automatically switch to methane.
22)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 car. As a
result of the switching logic described
above, a delay between the valve ticking
and the the green warning light
on
the instrument panel turning off is
completely normal.23)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 a
request for high performance (e.g.
overtaking, fully laden vehicle, steep hills)
the system may automatically switch to
petrol operation to guarantee the engine
power requested. The green warning light
on the instrument panel turns on to
indicate this. When the above conditions
are no longer present, the system
automatically restores methane operation.
The green warning light
turns off. To
achieve the automatic switching described
above, make sure that there is always
enough fuel in the petrol tank.

KNOWING YOUR CAR

Warning light What it means
amberiTPMS
(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.
amberLPG FUEL RESERVE
(for versions/markets, where provided)
The warning light switches on when the residual quantity of LPG drops below 1/5 of the tank capacity. On
certain versions a dedicated message is displayed.
amberMETHANE RESERVE (Natural Power versions)
The warning light switches on when the residual quantity of Methane drops below 1/5 of the tank capacity.
On certain versions a dedicated message is displayed.

KNOWING THE INSTRUMENT PANEL

71)If the car 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 car, 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.
72)If the system signals a pressure
decrease on a specific tyre, it is
recommended to check the pressure on all
four tyres.
73)The iTPMS does not relieve the driver
from the obligation to check the tyre
pressure every month; it is not to
be considered a system to replace
maintenance or a safety system.
74)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.
75)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.
76)The system only warns that the tyre
pressure is low: it is not able to inflate
them.
77)Insufficient tyre inflation increases fuel
consumption, reduces the tread duration
and may affect the capacity to drive safely.
WARNING
30)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.
31)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
you car, 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.
32)Projecting loads on the roof of the car
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.
33)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.34)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.
35)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.
36)If a trailer or a vehicle is towed the
system must be deactivated with the
display Setup Menu.

WARNING
47)For correct operation of the system,
sensors must always be clean from mud,
dirt, snow or ice. Be careful not to scratch
or damage the sensors while cleaning
them. Avoid using dry, rough or hard
cloths. The sensors must be washed using
clean water, with the addition of vehicle
shampoo if necessary. When using special
washing equipment such as high pressure
jets or steam cleaning, clean the sensors
very quickly keeping the jet more than
10 cm away.
REFUELLING THE
VEHICLE
128) 129) 130)
Always stop the engine before
refuelling.
PETROL ENGINES
Only use unleaded petrol, with an
octane number (R.O.N.) not lower than
95. In order to prevent damage to the
catalytic converter never introduce even
the smallest amount of leaded petrol,
even in the event of an emergency.
IMPORTANT An inefficient catalytic
converter leads to harmful exhaust
emissions, thus contributing to air
pollution.
IMPORTANT Never introduce leaded
petrol to the tank, even in small
amounts in an emergency, as this
would damage the catalytic converter
beyond repair.DIESEL ENGINES
Operation at low temperatures
Only use Diesel for motor vehicles
(EN590 specification).
When using or parking the car for a
long time in the mountains or cold
areas, it is advisable to refuel using
locally available diesel fuel. In this case,
it is also advisable to keep the tank
over 50% full.
REFUELLING
PROCEDURE
48)
IMPORTANT If the filler compartment is
washed with a high pressure jet, keep
it at a distance of at least 20 cm.
Diesel and petrol versions

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. Empty the tank.
If the engine has been run for even an
extremely limited amount of time, you must
not only drain the fuel tank, but the rest of
the supply circuit as well.
49)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.

SCHEDULED
SERVICING
Correct servicing is crucial for
guaranteeing a long life for the car
under the best conditions.
For this reason, Fiat has planned a
series of checks and services at fixed
distance and/or time intervals, as
described in the Service Schedule.
To keep the car’s efficiency in tip-top
condition, in the previous Scheduled
Service plan pages a few additional
checks are listed that should be carried
out more frequently with respect to
the normal coupon redemption
schedule.
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
the owner's explicit agreement only.
If your car is used frequently for towing,
the interval between one scheduled
servicing 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.
For cars with 0.9 TwinAir engines:
every3,000km check the engine oil
level and top it up to the maximum level
if necessary.DEMANDING USE OF THE
CAR
If the car 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 the cleanliness of the side,
bonnet and luggage compartment
locks, and the cleanliness and
lubrication of the linkages;
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
accessory drive belts;
check and, if necessary, change
engine oil and replace oil filter / pollen
filter / air cleaner.
