2018 Alfa Romeo Giulietta fuel reserve

LPG/PETROL SWITCH
20)
15)
This engine normally runs on LPG except
during starting when it runs on petrol.
Switching to LPG takes place
automatically and is indicated by the
switching-off of icon
on the display,
next to the letters LPG.
To switch to the other fuel type, press the
button
with the car stationary and
engine on, or while driving.
If the LPG runs out during LPG operation,
the system automatically switches over
to running on petrol.
The four bars near the letters LPG in the
display indicate the level of LPG in the
tank.
REFUELLING
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; 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 differentsupply/locking features, tank not
completely run out of fuel.
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.
WARNING
19)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.
20)Do not switch between the two
operating modes whilst starting the engine.
21)If gas is smelt, switch from LPG
operation to petrol operation and
immediately go to an Alfa Romeo Dealership
to have the vehicle checked and possible
system faults excluded.
IMPORTANT
10)The car is equipped with a specifically
designed gaseous LPG injection system: it is
therefore absolutely forbidden to alter the
configuration of the system or its
components. The use of other components or
materials could cause malfunctions and lead
to a reduction in safety; therefore, in the
case of problems, contact an Alfa Romeo
Dealership. When towing or lifting the
vehicle, follow the instructions in the main
handbook under the paragraph on "Towing
the vehicle" to prevent damage to the gas
system parts.
11)The system operates at temperatures
ranging between -20°C and 100°C.
12)When using a painting oven, the LPG
tank should be removed from the car and
later carefully refitted at an Alfa Romeo
Dealership. Although the LPG system has
numerous safety features, it is advisable to
proceed as follows every time the vehicle is
not in use for a long period or moved in an
emergency as a result of a breakdown or
accident: unscrew the devices fastening the
cover of the LPG tank, then remove it. Close
the LPG cock rotating the ring nut clockwise
(see "Passive safety / active safety"). Refit
the cover and retighten the fastening
devices.

GETTING TO KNOW YOUR CAR

13)Only use LPG for motor vehicles.
14)It is strictly forbidden to use any additive
in the LPG. Periodically (at least once every
six months) it is advisable to let the LPG in
the tank run out and, at the first refuelling, to
check that it does not exceed the maximum
capacity of 38 litres (reserve included) (with
a tolerance of 2 litres excess). If the level is
above 38 litres (reserve included) contact an
Alfa Romeo Dealership immediately.
15)When switching is requested, metallic
noise from the valves which pressurise the
circuit can be heard. For the switching logic
described above, a delay between the valve
ticking and the switching off of the
instrument panel indication is completely
normal.
16)In particular usage conditions, such as
starting and operation at low ambient
temperature or LPG supply with low propane
content, the system may switch temporarily
to petrol operation, without a visual
indication of switching on the instrument
panel. In the event of low LPG 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 green warning light on the
instrument panel switches on to indicate this.
When the above conditions are no longer
present, the system automatically restores
LPG operation; the green warning light
switches off. To achieve the automatic
switching described above, make sure that
there is always enough fuel in the petrol tank.

DISPLAY
The car is equipped with a reconfigurable
multifunction display that, according to
the previously applied settings, will show
useful driving information.
With the ignition key removed, the
display lights up and shows the time and
total odometer reading (in km or miles)
for a few seconds when a door is
opened/closed.
RECONFIGURABLE MULTIFUNCTION
DISPLAY
The following information is shown on the
display (example given in fig. 38 ):
1: Time
2: Area reserved for messages
(information, settings, etc)
3: Milometer (total distance covered
in km or miles).4: Car status indications (e.g. doors open,
possible ice on road, etc.)/Start&Stop
function indication (for versions/
markets, where provided)/Gear Shift
Indicator (for versions/markets, where
provided)
5: Headlight alignment position (only with
dipped beam headlights on)
6: External temperature
The turbocharger pressure will appear on
some versions when “DYNAMIC” driving
mode is selected (see “Alfa DNA system”
in this chapter).GEAR SHIFT INDICATOR
The GSI (Gear Shift Indicator) system
advises the driver to change gear through
a special indication on the display.
Through the GSI, the driver is notified
that the gear change will allow a
reduction in fuel consumption.
Therefore, for driving oriented towards
reducing fuel consumption, it is advisable
to stick to “Natural” or “All Weather”
mode and to follow the suggestions of
the Gear Shift Indicator, where traffic
conditions permit.
When the SHIFT UP icon
is shown on
the display the GSI suggests the driver to
up-shift, whereas if the SHIFT DOWN
icon
is displayed, the driver is advised
to down-shift.
The indication in the instrument panel
remains on until the driver shifts gear or
the driving conditions go back to a
situation where gearshifting is not
required to improve consumption.

KNOWING THE INSTRUMENT PANEL

Warning lights on
panelWhat it means What to do
FUEL RESERVE/LIMITED RANGE
The warning light turns on when about8-10litres of fuel
are left in the tank.
When the remaining range is lower than approx. 50 km (or
equivalent value in miles), on some versions the display
will show a warning message.
25)
REAR FOG LIGHTS
This warning light comes on when the rear fog lights are
switched on.
ABS FAILURE
The warning light switches on when the ignition key is

The warning light switches on to indicate a system fault. In
this case the braking system maintains its efficiency
unaltered but without the advantage of the ABS system.Drive carefully and contact an Alfa Romeo Dealership as
soon as possible.
