LPG MULTIPOINT
INJECTION SYSTEM
This product is produced by working
closely with qualified suppliers in the
LPG sector.
The injection system used on the car is
an efficient system in terms of engine
performance and is based on the
injection of LPG in a gaseous state.
In this system with four injectors, one
for each intake manifold, the fuel is
injected directly into the engine heat
transfer ducts, thereby metering the
LPG very precisely improving
combustion and, at the same time,
excluding any possibility of flame return.
By adapting the electronic control
technology of petrol engines to meet
LPG specifications, significant results in
terms of driveability and controlling
exhaust emissions have been obtained.
When running on LPG the engine has
almost the same torque and power
features as when running on petrol:
consequently, the car performance can
be compared.
SELECTION OF THE FUEL
SUPPLY TYPE
The car is configured for running
independently on either petrol or LPG.
The engine always starts up on petrol,
with automatic switching to LPG whenthe best conditions are achieved
(engine water temperature, minimum
engine rpm limit) for switching to LPG.
In addition, it is advisable to periodically
use up the petrol in the tank (until the
reserve warning light comes on) in order
to ensure that the petrol does not
become old and possibly deteriorate.
The petrol/LPG switch fig. 69 allows
drivers to select petrol or LPG
operation.
IMPORTANT There must therefore
always be some petrol in the tank to
protect the petrol pump and to
guarantee temporary switching from
LPG to petrol operation, if high
performance is required.PASSIVE SAFETY/ACTIVE
SAFETY
Passive safety
The car has the same passive safety
specifications as other versions. In
particular, the mountings of the tank
(located in the space-saver wheel
housing) have been designed to comply
with the Fiat safety standards for impact
tests.
When running on LPG, the flow of gas
(in a liquid state) leaving the tank
passes through the specific piping to
the pressure regulator unit, where there
is a safety solenoid valve that stops the
flow of LPG when the ignition key is
removed or when the driver selects a
fuel change (decision to run on petrol).
Together with the regulator solenoid
valve, a second solenoid valve, in the
tank, closes the LPG piping at the tank
outlet.
The two solenoid valves are connected
to the fuel cut-off system (Fire
Protection System).
The LPG tank complies with the current
legal regulations of the countries where
the car is sold.
Active safety
The car has the same active safety
specifications as other versions.

KNOWING YOUR CAR
at least 20 minutes) which starts when
the RESET procedure is carried out.
The RESET procedure must be carried
out:
each time tyre pressure is modified;
when even only one tyre is changed;
when tyres are rotated/inverted;
when the space-saver wheel is fitted.
Before carrying out the RESET
procedure, inflate the tyres to the rated
pressure values specified in the inflation
pressure table (see "Wheels" paragraph
in the "Technical specifications"
chapter).
If the RESET is not carried out, in all
above cases, the
warning light may
give false indications on one or more
tyres.
To carry out the RESET, with the vehicle
stationary and the engine on, hold
down the Reset button
located on
the left control panel fig. 92 for at least
2 seconds.
When the RESET procedure has been
carried out, and depending on the type
of instrument panel, either only a buzzer
will be heard or the message "Reset
saved" will appear together with the
buzzer to indicate that self-learning has
started.Operating conditions
The system is active for speeds above
15 km/h.
In a few situations such as sporty
driving, particular conditions of the road
surface (e.g. icy, snowy, unsurfaced
roads) the signalling may be delayed or
partial in detecting the contemporary
deflation of more than one tyre.
Under special conditions (e.g. vehicle
loaded asymmetrically on one side,
towing a trailer, damaged or worn tyre,
fitting the space-saver wheel, use of the
"Fix&Go Automatic" tyre repair kit, fitting
snow chains, fitting different tyres on
the axles) the system may provide false
indications or be temporarily
deactivated.
If the system is temporarily deactivated
the
warning light flashes for about
75 seconds and then is continuouslyon; at the same time, the display shows
a warning message.
This indication is displayed also after
the engine has been switched off and
then on again if the correct operating
conditions are not restored.
In the case of abnormal signals, it is
recommended to perform the RESET
procedure. If the signals reappear once
the RESET procedure has started,
check that the type of tyres used are
the same on all four wheels and that the
tyres are not damaged; if the
space-saver wheel is being used, refit
the wheel with a tire with normal
dimensions instead of the space-saver
wheel as soon as possible; if possible
remove the snow chains; make sure
that the load is distributed correctly and
repeat the RESET procedure, driving on
a clean and surfaced road. If the signals
persist, contact a Fiat Dealership.
WARNING
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.
