FIAT IDEA LPG
The system extreme operat-
ing temperatures are between
-20°C and 100°C.
Selecting the type of fuel supply
The car is configured to run independently
on either petrol or LPG.
The engine is always started on petrol
with an automatic shift to LPG after about
40 seconds, at the first significant accel-
eration.
This is the time required to reach opti-
mum conditions (engine coolant temper-
ature, minimum revs level) for the switch
to LPG. As far as what has been said
is concerned, there must always be
some petrol in the tank (at least 1/4
full)in order not to compromise fuel
pump operation.
In addition, from time to time it is advis-
able to use up all 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. When running on LPG, when
the last red LED gas quantity
indicator (visible on the
switch) comes on, you should
refuel. If the LPG runs out during LPG
operation, the system automatically
switches to running on petrol shown by:
the amber LED coming on constantly
and the green LED flashing, the fuel
level LEDs going out and a buzzer
sounded by the switch.
The petrol/LPG switch A - Fig. 1, locat-
ed on the protective fuse compartment
(on the left of the dashboard) allows the
driver to select petrol or LPG operation
at your own discretion.

Please remember that after
filling the LPG tank, you will
need to switch fuel by press-
ing the button A-fig 1 to run
the engine on LPG.
The LPG supply system is
equipped with a "consump-
tion" function linked to the LED display
of LPG level on the switch; this function
activates only after a consistent varia-
tion in fuel level has been detected. You
are therefore advised to fill up with fu-
el at the first LPG refuelling to obtain a
more precise indication of the “level".

(*) The figure already takes into account
the 80% tank filling limit and the residual
fluid required for the pump, it is the max-
imum permitted capacity. There may be
slight variations to this figure as a re-
sult of: differences between the supply
pressures of pumps in the network,
pumps with different supply/cut off
specifications, tank not completely in
reserve condition.Note than when using a fuel such as LPG,
the range is very variable because, in ad-
dition to the vehicle driving and mainte-
nance conditions, it also depends on the
composition of the gas which may vary,
not only seasonally, but also from suppli-
er to supplier. LPG is, in effect, a compo-
sition of gas (butane and propane) mixed
in a way that may not be standardised.
The trip meter indication on range is in-
dicative and refers to petrol operation on-
ly.
During LPG operation, the ‘Instant con-
sumption’ and ‘Average consumption’
readings are not significant, whereas all
other functions remain valid.
IMPORTANT Only use LPG for mo-
tor vehicles. If, when refuelling with LPG,
the tank is filled with more
than the 31 litres, seek imme-
diate assistance from a Fiat
Dealer. Periodically (at least once
every six months) it is advisable to let
the LPG in the tank run out and, at the
first refuelling, check that it does not
exceed the maximum capacity of 31
litres.
The LPG supply system is
equipped with a "consump-
tion" function linked to the LED display
of LPG level on the switch; this function
activates only after a consistent varia-
tion in fuel level has been detected. You
