fuel pressure Alfa Romeo Giulietta 2018 Owner's Manual

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

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
Low tyre pressure
The warning light switches on constantly to indicate that the tyre
pressure is lower than the recommended value, in order to
guarantee long tyre life and low fuel consumption, or to indicate a
slow loss of pressure.
In this way the iTPMS warns the driver that one or more tyres may
be flat and therefore probably punctured. In this case it is
advisable to restore the correct pressure value (see the "Wheels"
paragraph in the "Technical specifications" section).
Once the normal operating conditions of the vehicle are restored,
carry out the Reset procedure.In any situation in which the message on the
display is "See manual", it is ESSENTIAL to refer
to the contents of the "Wheels" paragraph in the
"Technical specifications" section, strictly
complying with the indications that you find
there.
IMPORTANT Do not continue driving with one or
more flat tyres as handling may be compromised.
Stop the vehicle, avoiding sharp braking and
steering.
ELECTRONIC STABILITY CONTROL (ESC) SYSTEM
When the ignition key is turned to MAR, the warning light switches
on, but should switch off as soon as the engine is started.
Intervention by the system is indicated by the flashing of the
warning light: it indicates that the car is in critical stability and grip
conditions.
If the warning light does not switch off, or if it stays on with the
engine running, this indicates an anomaly in the ESC system.Contact an Alfa Romeo Dealership as soon as
possible to have the problem diagnosed and
resolved.
ELECTRONIC STABILITY CONTROL (ESC) SYSTEM
ASR system failure
When the ignition key is turned to MAR, the warning light switches
on, but should switch off as soon as the engine is started.
The warning light will flash while driving to indicate that the ASR
system is intervening.
If the warning light does not switch off, or if it stays on with the
engine running, this indicates a malfunction of the ASR system.In this case, contact an Alfa Romeo Dealership as
soon as possible.
Hill Holder failure
The warning light switches on together with the symbol
on the
display to indicate a fault in the Hill Holder system.In this case, contact an Alfa Romeo Dealership as
soon as possible.

KNOWING THE INSTRUMENT PANEL

when the space-saver wheel is fitted.
Before carrying out the RESET, 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 car
stopped and the ignition key at MAR-ON,
press the button
fig. 40 on the
dashboard for 2 seconds; after the
RESET, the display shows a dedicated
message, indicating that "self-learning"
has started.
OPERATING CONDITIONS
47) 48) 49) 50) 51) 52)
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" kit, fitting snow
chains, fitting different tyres on the
axles) the system may give false
indications or be temporarily
deactivated.
If the system is temporarily deactivated,
the warning light
flashes for about
75 seconds and then is continuously on;
at the same time, the display shows a
dedicated 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.
IMPORTANT NOTES
WARNING
47)If the system signals a pressure
decrease on a specific tyre, it is
recommended to check the pressure on all
four tyres.
48)The iTPMS does not relieve the driver
from the obligation to check the tyre
pressure every month; it is not to be
considered a system to replace maintenance
or a safety system.
49)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.
50)The iTPMS cannot indicate sudden tyre
pressure drops (for example when a tyre
bursts). In this case, stop the vehicle, braking
with caution and avoiding abrupt steering.
51)The system only warns that the tyre
pressure is low: it is not able to inflate them.
52)Insufficient tyre inflation increases fuel
consumption, reduces the tread duration and
may affect the capacity to drive safely.

Pulling the cord releases the flap lock: the
flap can then can be opened by pressing
it.
IMPORTANT NOTE If there is no
emergency flap opening device, contact
the Alfa Romeo Dealership in the event
of an emergency.
Closing
Release cap 1 from device 3 and insert it
in its housing. Then tighten the cap
clockwise until one or more clicks are
heard. Finally, close flap 2 and make sure
