2018 FIAT 500X fuel pressure

LPG TANK
16)
The car has a pressurised tank for
storing LPG in a liquid state. It is
toroidal and is located in the spare
wheel compartment with suitable
protection.
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 car 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 all case, when the
time limit for your country has
expired, go to a Fiat Dealer to have
the tank replaced.
LPG/PETROL SWITCH
30)
18) 19) 20)
This engine normally runs on LPG
except during starting when it runs on
petrol.
Switching to LPG is automatic: the
green warning light
on the
instrument panel turns off.
To change fuel type, press the
button on the dashboard fig. 54with
the car stationary and engine running,
or while driving.
If the LPG runs out during LPG
operation, the system automatically
switches over to running on petrol.
The four bars on the digital indicator
near the letters LPG on the instrument
panel indicate the level of LPG in the
tank.
REFUELLING
17) 21) 22) 23)
LPG
Maximum refuelling capacity (including
reserve) (*): 38 litres
(*) The figure already takes into account
the 80% tank filling limit and the
residual fluid required for priming; 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.
Note that when using a fuel such as
LPG, the range is very variable
because, in addition to the vehicle
driving and servicing conditions, it also
depends on the composition of the gas
which may vary, not only seasonally, but
also from supplier to supplier. LPG is, in
effect, a composition of gas (butane
and propane) mixed in a way that may
not be standardised.
IMPORTANT In order to avoid
inconsistent information by the LPG
gauge on the instrument panel, it is
recommended to refill with at least
10 litres each time.

GETTING TO KNOW YOUR CAR

Warning lightWhat it means
yellowiTPMS
iTPMS failure
When an iTPMS system failure is detected, the light flashes for 75 seconds, then stays on and a warning
message appears. This also happens if there are one or more wheels without sensors, until initial
conditions are restored.
IMPORTANT Do not continue driving with one or more flat tyres as handling may be compromised. Stop
the vehicle, avoiding sharp braking and steering. Repair immediately using the dedicated tyre repair kit (see
the “Fix&Go Automatic kit” paragraph in the "In an emergency" chapter) and contact a Fiat Dealership as
soon as possible.
Tyre pressure low
The warning light switches on and a message is displayed to indicate that the tyre pressure is lower than
the recommended value and/or that slow pressure loss is occurring. In these cases, optimal tyre duration
and fuel consumption may not be guaranteed.
In any situation in which the dedicated message is shown on the display, it is ESSENTIAL to refer to the
contents of the "Wheels" paragraph in the "Technical data" chapter, strictly complying with the indications
that you find there.
Once the normal operating conditions of the car are restored, carry out the "Reset" procedure.
WARNING Do not continue driving with one or more flat tyres as the car handling may be compromised.
Stop the vehicle, avoiding sharp braking and steering.
yellow
ABS FAILURE
The warning light switches on to indicate an ABS fault. In this case the braking system maintains its
efficiency unaltered but without the advantage of the ABS system. Drive carefully and contact a Fiat
Dealership as soon as possible.

SymbolWhat it means
yellowFUEL LEVEL SENSOR FAILURE
The symbol switches on in the event of fuel level sensor failure. Contact a Fiat Dealership.
yellow LPG FUEL SUPPLY SYSTEM FAILURE
The symbol on the display turns on in the event of an LPG fuel system failure. In this case, all the bars on
the digital indicator will be off.
In the event of a failure, contact a Fiat Dealership.
yellowENGINE OIL DETERIORATED
(where provided)
Diesel versions: the symbol turns on and is displayed for 3 minute cycles and intervals of 5 seconds until
the oil is changed.
The symbol is displayed until the problem is solved.
Petrol versions: the symbol switches on and then is not displayed when the display cycle is completed.
IMPORTANT After the first indication, each time the engine is started the symbol will continue to switch on
as described above until the oil is changed.
If the symbol flashes, this does not mean that there is a fault on the vehicle, rather it simply reports that it is
now necessary to change the oil as a result of regular use of the vehicle.
The deterioration of engine oil is accelerated by using the car for short drives, preventing the engine from
reaching operating temperature.
Contact a Fiat Dealership as soon as possible.

yellow
ENGINE OIL PRESSURE SENSOR FAILURE
The symbol switches on constantly together with the message in the display in the case of engine oil
pressure sensor failure.

WARNING
60)The system is an aid for vehicle driving,
it DOES NOT warn the driver about
incoming vehicles outside of the detection
areas. The driver must always maintain a
sufficient level of attention to the traffic and
road conditions and for controlling the
trajectory of the vehicle.
61) The system is an aid for the driver, who
must always pay full attention while driving.
The responsibility always rests with the
driver, who must take into account the
traffic conditions in order to drive in
complete safety. The driver must always
maintain a safe distance from the vehicle in
front.
62) If the driver depresses the brake pedal
fully or carries out a fast steering during
system operation, the automatic braking
function may stop (e.g. to allow a possible
manoeuvre to avoid the obstacle).
63) The system intervenes on vehicles
travelling in the same lane. People, animals
and things (e.g. pushchairs) are not taken
into consideration.
64) If the car must be placed on a roller
bench 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
settings of the Uconnect™system.
65) If the iTPMS system signals a pressure
decrease on the tyres, it is recommended
to check the pressure on all four tyres. 66)
The 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.
67) 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
68) The iTPMS cannot indicate sudden tyre
pressure drops (e.g. if a tyre bursts). In this
case, stop the vehicle, braking with caution
and avoiding abrupt steering.
69) The system only warns that the tyre
pressure is low: it is not able to inflate
them.
70) Insufficient tyre inflation increases fuel
consumption, reduces the tread duration
and may affect the capacity to drive safely.
IMPORTANT
32) The system may have limited or absent
operation due to weather conditions such
as: heavy rain, hail, thick fog, heavy snow.
33) The section of the bumper before the
sensor must not be covered with
adhesives, auxiliary headlights or any other
object.
34) System intervention might be
unexpected or delayed when other vehicles
transport loads projecting from the side,
above or from the rear, with respect to the
normal size of the vehicle. 35)
Operation can be adversely affected by
any structural change made to the vehicle,
such as a modification to the front
geometry, tyre change, or a heavier load
than the standard load of the vehicle.
36) Incorrect repairs made on the front part
of the vehicle (e.g. bumper, chassis) may
alter the position of the radar sensor, and
adversely affect its operation. Go to a Fiat
Dealership for any operation of this type.
37) Do not tamper with nor carry out any
intervention on the radar sensor or on the
camera on the windscreen. In the event of
a sensor failure, contact a Fiat Dealership.
38) When towing a trailer (with modules
installed after purchasing the vehicle), a
vehicle or during loading manoeuvres on a
vehicle transporter (or in vehicle for
transport), the system must be deactivated
via the Uconnect™system.
39) Do not wash with high-pressure jets in
the bumper lower area: in particular do not
operate on the system's electrical
connector.
40) Be careful in the case of repairs and
new paintings in the area around the
sensor (panel covering the sensor on the
left side of the bumper). In the event of a
frontal impact the sensor may automatically
deactivate and display a warning to indicate
that the sensor needs to be repaired. Even
without a malfunction warning, deactivate
the system operation if you think that the
position of the radar sensor has changed
(e.g. due to low-speed frontal impact as
during parking manoeuvres). In these
cases, go to a Fiat Dealership to have the
radar sensor realigned or replaced.

WARNING
136)
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.
137) 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.
138) Do not use a mobile phone near the
refuelling pump: risk of fire.
IMPORTANT
76) Vehicles with a diesel engine 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
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.
