fuel pressure Lancia Ypsilon 2021 Owner handbook (in English)

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 provisions in force in that
country. In any case, when the time limit
in the individual country has run out,
contact a Lancia Dealership to have the
tank replaced.SELECTION OF

The petrol/LPG switch A fig. 38 allows
drivers to select petrol or LPG
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
icon on the display.
If the LPG runs out, switching to petrol
takes place automatically. In this case
the display shows the
icon just
above the LPG wording and all the bars
of the edges for the empty notches

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, 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
29)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.
30)Do not switch between the two
operating modes whilst starting the engine.

KNOWING YOUR CAR

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 (petrol/methane switch) button A
fig. 41 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
icon on the display.

KNOWING YOUR CAR

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 runs out, switching to
petrol takes place automatically. In this
case the display shows the
icon
just above the CNG wording and all the
bars of the edges for the empty
notches light up constantly.
REFUELLING
Maximum refuelling capacity (including
reserve): 12 kg. The total volume of
cylinders is about 72 litres.
WARNING
31)The car is equipped with a high-
pressure methane system designed to
operate at 200 rated bar. It is dangerous to
stretch the system with higher pressures.
To prevent damage to the methane system
parts when towing or raising the car,
follow the instructions in the "Towing the
vehicle" paragraph in the "In Emergency"
chapter. If there is a problem with the
methane system, only contact a Lancia
Dealership. Do not modify configuration or
components of the methane system;
they have been designed exclusively for
this car. The use of other components
or materials could cause malfunctions and
prejudice safety.32)When oven painting, the cylinders
should be removed from the vehicle and
later carefully refitted by a Lancia
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.
33)Do not switch between the two
operating modes whilst starting the engine.
WARNING
23)If, during methane operation, the same
runs out, the car switches to petrol
automatically and all the bars on the
display switch off. This displaying remains
until the next methane refuelling.
24)Regardless of the last fuel system
used, at the following engine starting, after
the initial petrol stage, the system will
automatically switch to methane.
25)When switching is requested, metallic
noise from the valves which pressurise
the circuit can be heard. For the switching
logics described above, a delay between
the valve ticking and the switching off
of the indication on the display is absolutely
normal.26)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, car fully laden, steep hills) the
system may automatically switch to petrol
operation to guarantee the engine power
requested; the
icon on the display
switches on to indicate this. When the
above conditions are no longer present,
the system automatically restores methane
operation and the
icon switches off.
To achieve the automatic switching
described above, make sure that there is
always enough fuel in the petrol tank.

The GSI (Gear Shift Indicator) system
advises the driver to change gear
through a specific indication on the
control panel.
Through the GSI, the driver is notified
that changing gear will allow a
reduction in fuel consumption.
When the SHIFT UP icon (
SHIFT) is
shown on the display, the GSI advises
the driver to engage a higher gear,
while when the SHIFT DOWN icon (
SHIFT) is shown, the GSI advises the
driver to engage a lower gear.
The indication on the instrument panel
remains until the driver shifts gear or the
driving conditions return to a situation
where gearshifting is not required to
improve consumption.

Warning light What it means
iTPMS
(for versions/markets, where provided)
Tyre pressure low
The warning light (or symbol for versions with multifunction reconfigurable display) 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 (or symbol for versions with multifunction reconfigurable display) 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 Lancia Dealership as soon as possible.
59

Under special conditions (e.g. car
loaded asymmetrically on one side,
towing a trailer, damaged or worn tyre,
fitting the space-saver wheel, use of the
"Fix&Go Automatic" kit, fitting snow
chains, fitting different tyres on the
axles) the system may give false
indications or be temporarily
deactivated.
If the system is temporarily deactivated,
the warning light
flashes for about
75 seconds and then is continuously
on; at the same time, the display shows
a dedicated message.
This warning is displayed also after the
engine has been switched off and
then on again if the correct operating
conditions are not restored.
WARNING
67)If the system signals a pressure
decrease on a specific tyre, it is
recommended to check the pressure on all
four tyres.
68)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.69)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.
70)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.
71)The system only warns that the tyre
pressure is low: it is not able to inflate
them.
72)Insufficient tyre inflation increases fuel
consumption, reduces the tread duration
and may affect the capacity to drive safely.
OCCUPANT
PROTECTION
SYSTEMS
some of the most important safety
equipment of the vehicle comprise the
following protection systems:
seat belts;
SBR (Seat Belt Reminder) system;
head restraints;
child restraint systems;
Front airbags and side bags.
Read the information given the
following pages with the utmost care. It
is of fundamental importance that the
protection systems are used in the
correct way to guarantee the maximum
possible safety level for the driver and
the passengers.
For the description of the head restraint
adjustment see the "Head restraints"
paragraph in the "Knowing your
vehicle" chapter.

hand the special filler adapter (see
the following description) over to the
qualified LPG refuelling personnel.
IMPORTANT Depending on the country,
there are various types of adapters for
the refuelling pump. Adapter A fig.
80, supplied with the car and located in
a special case, is specifically designed
for the country in which the car is
sold. If you are in a different country,
find out what type of adapter is used
there.Natural Power versions
50)
To access the filler C fig. 81, open the
fuel flap A and undo the cap B turning it
counterclockwise.
The profile of the filler C for refilling is
the universal type compatible with
Italian and NGV1 standards.
In some European countries adapters
are considered ILLEGAL (e.g. in
Germany).
WARNING
46)Do not apply any object/plug to the
end of the filler which is not provided
for the car. The use of non-compliant
objects/plugs could cause a pressure
increase inside the tank, resulting in
dangerous situations.47)Do not bring naked flames or lit
cigarettes near to the fuel filler: fire risk.
Keep your face away from the fuel filler to
prevent breathing in harmful vapours.
48)Do not use a mobile phone near the
refuelling pump: risk of fire
49)For diesel engines, only use diesel fuel
for motor vehicles in accordance with
EN 590 European specifications. 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. 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.
50)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.
