2008 FIAT IDEA fuel reserve

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".

ELECTRONIC
CONTROL UNIT
The vehicle has a dedicated electronic
control unit for the LPG system; it uses
the incoming signals from the petrol in-
jection control unit and converts them in-
to signals for LPG injection.
The injector control unit works in the
same way as the petrol control unit
(phased, sequential, multipoint).
LPG/PETROL SWITCH
The LPG/petrol switch fig. 7is located
near the protective fuse compartment (on
the left of the dashboard) and includes:
A. LPG/petrol operating mode request
button;
B. LPG gauge: 5 LEDs, 4 green and 1 red
to indicate the reserve. The red LED on-
ly comes on when the last green LED goes
out.
The red LED indicates that you are run-
ning on reserve;
ON. LPG operating mode indicator:
green LED, located under button A, on
constantly;
OFF. petrol operating mode indicator:
yellow LED, located above button A, on
constantly.
IMPORTANT When the ignition key is set
to MAR, the LEDs on the ignition switch
come on in accordance with the following
logic:
– with the petrol operating mode se-
lected: yellow OFFLED on;
– with the LPG operating mode se-
lected: all the LEDs in the switch are on
constantly and the green ONLED flash-
es.To select the type of fuel system desired
(LPG or petrol), press button A - Fig. 7.
To change the type of fuel system, it is ad-
visable to operate the button with the ve-
hicle stationary and the engine running or,
whilst driving, after having released the ac-
celerator.
If switching takes place during acceleration
or pick-up, there may be a brief flat spot
(drop in power).

Do not switch between the
two operating modes whilst
starting the engine.

Switch from petrol to LPG
When running on petrol: press button A
- Fig 7, the switch to LPG will take place
automatically at the first significant accel-
eration.
During switching:
– the LPG gauge Bcomes on;
– the yellow OFFLED goes out (petrol
operating mode);
– the green ONLED comes on, switch-
ing from intermittent to on constantly
(LPG operating mode);
There are 5 LEDs B(1 red and 4 green)
on the left of the switch that display the
amount of LPG in the tank.
When the amount of LPG remaining falls
below about 1/5 of the capacity of the
tank, only the red (reserve) LED remains
on, signalling the need to refuel.
IMPORTANT Where starting the engine
in external temperatures of below -10°C,
switching times from petrol to LPG in-
crease to allow the pressure regulator to
become warm enough.IMPORTANT The buzzer warns the dri-
ver that the engine is running on petrol;
therefore they must refuel with LPG be-
fore it runs out.
THE buzzer can be deactivated by press-
ing switching button A.
Do not switch between the
two operating modes whilst
starting the engine.Switching from LPG to petrol
When running on LPG: press buttonA -
fig. 7.
During switching:
– the LPG gauge Bgoes out;
– the yellow OFF LED comes on con-
stantly (petrol operating mode);
– the green ONLED goes out (LPG op-
erating mode).
LPG used up
If the LPG runs out, switching to petrol
takes place automatically with:
– the yellow OFFLED on constantly;
– the green ONLED flashing;
– an acoustic warning sounded by the
switch buzzer (fast frequency).

(*) 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
are therefore advised to fill up with fu-
el at the first LPG refuelling to obtain a
more precise indication of the “level".
