ALFA ROMEO CODESYSTEM
The Alfa Romeo Code prevents
unauthorised use of the vehicle, disabling
engine starting.
1)
Operation
Each time the car is started by turning
the ignition key to MAR, the Alfa Romeo
CODE system control unit sends an
acknowledgement code to the
Powertrain Control Module to deactivate
the inhibitor.
The code is sent only if the Alfa Romeo
CODE system control unit has recognised
the code transmitted by the key.
Each time the ignition key is turned to
STOP, the Alfa Romeo CODE system
deactivates the functions of the
Powertrain Control Module.
Irregular operation
If, during starting, the code is not
correctly recognised, the icon
appears on the instrument panel.
In this case, turn the key to STOP and
then to MAR-ON; if it is still locked, try
again with the other keys that come with
the car. If it is still not possible to start
the engine, contact an Alfa Romeo
Dealership.Activation of warning light while
driving
If the iconappears on the display,
this means that the system is running a
self-diagnosis (for example due to a
voltage drop).
If the iconcontinues to be
displayed, contact an Alfa Romeo
Dealership.
IMPORTANT
1)The electronic components inside the key
may be damaged if the key is subjected to

LPG TANK
The car has a (pressurised) tank A for
storing LPG in a liquid state. It is toroidal
and is located in the spare wheel
compartment with suitable protection.
LPG tank certification
The LPG tank is certified in accordance
with the regulations in force.
In Italy, the tank has a life of 10 years
starting from the car registration date. If
the vehicle has been registered in a
country other than Italy, the duration and
the testing/inspection procedures of the
LPG tank can vary depending on the
national provisions in force in that
country. In any case, when the time limit
in the individual country has run out, go to
an Alfa Romeo Dealership to have the
tank replaced.
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 different
supply/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.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.

GETTING TO KNOW YOUR CAR

Warning lights on
panelWhat it means What to do
LOW ENGINE OIL PRESSURE
When the key is turned to MAR the warning light comes on, but should go out as soon
as the engine is started.
After turning the ignition key to MAR, wait for about 2 seconds before starting the
engine.
The warning light switches on constantly together with a message on the display (for
versions/markets, where provided) when the system detects that engine oil
pressure is low.
IMPORTANT Do not use the vehicle until the failure has been solved.
IMPORTANT To find out the correct oil quantity, always check using the dipstick.
17)
DEGRADED ENGINE OIL (for versions/markets, where provided)
The warning light will turn on flashing together with a dedicated message on the
display (for versions/markets where provided).
Depending on the versions, the warning light flashing modes are as follows:
- for 1 minute every two hours;
- for 3 minute cycles with the warning light off for intervals of 5 seconds until oil is
changed.
After the initial warning, each time the engine is started up, the warning light will
continue to flash in the same mode, until the oil is changed. A specific message will
appear on the display (for versions/markets, where provided) in addition to the
warning light. If the warning light flashes, this does not mean that there is a fault, but
simply informs that it is now necessary to change the oil as a result of regular use of
the car. Engine oil deterioration is accelerated by:
- mainly town use of the car which makes the DPF regeneration process more
frequent;
- use of the vehicle for short drives, in which the engine does not have time to reach
its regular operating temperature;
- repeated interruptions of the regeneration process, signalled by the DPF warning
light switching on.Contact an Alfa Romeo
Dealership as soon as
possible.

KNOWING THE INSTRUMENT PANEL

Warning lights on
panelWhat it means What to do
ENGINE COOLANT TEMPERATURE TOO HIGH
The warning light switches on when the ignition key is
turned to MAR, but it should switch off after a few
seconds. The warning light turns on when the engine is
overheated.
The display shows the dedicated message.In normal driving conditions: stop the car, switch off the
engine and check that the water level in the reservoir is
not below the MIN mark. In this case, wait for the engine
to cool down, then slowly and carefully open the cap, top
up with coolant and check that the level is between the
MIN and MAX marks on the reservoir itself. Also check
visually for any fluid leaks. Should the warning light turn
on again at the next start-up, contact an Alfa Romeo
Dealership.
If the vehicle is used under demanding conditions: (e.g. in
high-performance driving): slow down and, if the warning
light stays on, stop the vehicle. Wait for 2 or 3 minutes
with the engine running and slightly accelerated to
further favour the coolant circulation. Then stop the
engine. Check that the coolant level is correct as
described above.
IMPORTANT Over demanding routes, it is advisable to
keep the engine on and slightly accelerated for a few
minutes before switching it off.
ALFA TCT FAILURE
(for versions/markets, where provided)
The warning light switches on when the ignition key is
turned to MAR, but it should switch off after a few
seconds.
The warning light flashes (together with a message in the
display and an acoustic signal) to indicate that the
gearbox is faulty.
The warning light can switch on even in the case of
transmission overheating, after a particularly demanding
use. In this case an engine performance limitation is
carried out.Contact an Alfa Romeo Dealership as soon as possible.
If it is necessary to start the engine with a transmission
failure, follow the procedure described in the "Alfa TCT"
paragraph, in chapter "Starting and driving".

Warning lights on
panelWhat it means What to do
INJECTION/EOBD SYSTEM FAILURE
In normal conditions, when the ignition key is turned to MAR the
warning light switches on, but it should switch off as soon as the
engine is started. The operation of the
warning light may be
checked by the traffic police using specific devices. Comply with
the laws and regulations of the country where you are driving.18)
If the warning light remains on or switches on whilst driving, it
means that the injection system is not working properly. The
warning light on constantly signals a malfunction in the
supply/ignition system which could cause high exhaust emissions,
a possible loss of performance, poor driveability and high
consumption.
The warning light goes out after the fault disappears: the
indication is stored in the system.Under these conditions, the vehicle can continue
travelling at moderate speed without
demanding excessive effort from the engine.
Prolonged use of the car with the warning light
on constantly may cause damage.
Contact an Alfa Romeo Dealership as soon as
possible.
Petrol engines only
If the warning light flashes, it means that the catalytic converter
may be damaged.In this case, release the accelerator pedal to
lower the speed of the engine until the warning
light stops flashing. Continue the journey at
moderate speed, trying to avoid driving
conditions that may cause further flashing and
contact an Alfa Romeo Dealership as soon as
possible.
GLOW PLUG HEATING/GLOW PLUG HEATING FAILURE (diesel
versions)
This warning light switches on when the key is turned to MAR. It
will switch off as soon as the heater plugs have reached a preset
temperature. The engine can be started as soon as the warning
light switches off.
IMPORTANT In mild or high temperature conditions, the warning
light comes on for a very short time only.
Glow plug preheating failure
The warning light will flash to indicate a failure in the glow plug
preheating system.Contact an Alfa Romeo Dealership as soon as
possible.

KNOWING THE INSTRUMENT PANEL

WARNING
22)If thewarning light does not switch on when the ignition device is moved to ON or if it stays on when driving (together with the message on
the display), there might be a fault in the restraint systems; in this case, the airbags or pretensioners may not deploy in the event of an accident or,
in a lower number of cases, they could deploy erroneously. Before proceeding, contact an Alfa Romeo Dealership to have the system checked
immediately.
23)A fault with the warning light
is signalled by illumination of the iconon the instrument panel display and by the flashing of passenger
airbag disabled warning light on the rearview mirror. In addition, the airbag system automatically disables the airbag on the passenger's side (for
versions/markets where provided). In this case, the warning light may not indicate any faults with the restraint systems. Before proceeding,
contact an Alfa Romeo Dealership to have the system checked immediately.
24)If the warning light comes on, the exhausted engine oil should be changed as soon as possible, never drive more than 500 km from the first
switching-on of this warning light. Failure to observe the above may result in severe damage to the engine and invalidate the warranty. Remember
that when this warning light comes on, it does not mean that the level of engine oil is low, so if it flashes you must not top up the engine oil.
25)If the warning light flashes with the car in motion, contact an Alfa Romeo Dealership.
26)If the warning light (or the icon on the display) flashes whilst driving, contact an Alfa Romeo Dealership.
27)Always drive at a speed appropriate to the traffic conditions, the weather and traffic regulations. The engine may be switched off even if the
warning light is on: repeated interruptions of the regeneration process could cause an early deterioration of engine oil. For this reason it is
always advisable to wait for the symbol to go off before turning off the engine, following the instructions above. Do not complete the DPF
regeneration process when the vehicle is stopped.
IMPORTANT
17)If thewarning light switches on when driving, stop the engine immediately and contact an Alfa Romeo Dealership.
18)If, turning the ignition device to MAR, the warning lightdoes not turn on or if it turns on steadily or flashing when travelling (on some
versions together with the message on the display), contact an Alfa Romeo Dealership as soon as possible.
19)The presence of water in the fuel system circuit may cause severe damage to the injection system and irregular engine operation. If the
symbol is displayed contact an Alfa Romeo Dealership as soon as possible to bleed the system. If the above indications come on immediately
after refuelling, water has probably been introduced into the tank: stop the engine immediately and contact an Alfa Romeo Dealership.
