PARKING ON FLAMMABLE MATERIAL
The catalytic converter develops high temperatures during operation. Do not park the car on grass, dry leaves, pine needles or other flammable
material: fire hazard.
RESPECTING THE ENVIRONMENT
The vehicle is fitted with a system that carries out a continuous diagnosis of the emission-related components in order to help protect the
environment.
ELECTRICAL ACCESSORIES
If, after buying the car, you decide to add electrical accessories (with the risk of gradually draining the battery), contact an Alfa Romeo Dealership.
They will calculate the overall electrical requirement and check that the car’s electrical system can support the required load.
SCHEDULED SERVICING
Correct maintenance of the car is essential for ensuring that it maintains its performance and its safety features, its environmental friendliness and
low running costs for a long time to come.
THE OWNER HANDBOOK CONTAINS
…important information, advice and warnings for correct use, driving safety and maintenance of the car over time. Special attention must be paid to
the symbols(personal safety)(environmental protection)(car integrity).

SAFE LOCK DEVICE(where provided)
This safety device inhibits the operation
of the interior door handles and the door
locking/unlocking button. We recommend
that you activate this device each time
you park your car.
Activating the device
The device is enabled on all the doors by
pressing the button
on the key twice
quickly. Device activation is indicated by
3 flashes of the direction indicators and a
flash of the LED on the button
on the

IMPORTANT
1)Used batteries may be harmful to the
environment if not disposed of correctly.
They must be disposed of as specified by law
in the special containers or taken to an Alfa
Romeo Dealership, which will take care of
their disposal.
IGNITION DEVICE
2) 3)
The key can be turned to three different
positions fig. 6:
STOP: engine off, key can be removed,
steering column locked. Some electrical
devices (e.g. central door locking system,
alarm, etc.) are enabled;

(e.g. installation of anti-theft device) that
could adversely affect performance and
safety, invalidate the warranty and also
result in the car not meeting type-approval
requirements.
5)Never remove the key while the car is
moving. The steering wheel will
automatically lock as soon as it is turned.
This holds true for cars being towed as well.
ALFA ROMEO CODESYSTEM
The Alfa Romeo Code prevents
unauthorised use of the vehicle, disabling
engine starting.
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
strong shocks. In order to ensure complete
efficiency of the electronic devices inside the
key, it should never be exposed to direct
sunlight.

OPENING
Proceed as follows:
pull lever 1 fig. 30 in the direction
indicated by the arrow;
pull lever 2 in the direction indicated
by the arrow;
raise the bonnet and simultaneously
release the support stay 3 from its
blocking device, then insert the end in the
housing 4, ensuring to trigger the stay in
the smallest hole of retaining clip.
IMPORTANT Before raising the bonnet,
make sure that the arms of the wipers
are not raised from the windscreen and
that the wiper is not operational.CLOSING
Proceed as follows:
hold the bonnet up with one hand and
with the other remove the stay 3
fig. 31 from the housing 4 and fit it back
in its locking device;
lower the bonnet to approximately
20 centimetres from the engine
compartment and let it drop. Make sure
that the bonnet is completely closed and
not only fastened by the locking device
by trying to open it. If it is not perfectly
closed, do not try to press the bonnet
down but open it and repeat the
procedure.
IMPORTANT Always check that the
bonnet is closed correctly to prevent it
from opening while the vehicle is
travelling.
WARNING
17)For safety reasons, the bonnet must
always be properly closed while the car is
travelling. Therefore, make sure that the
bonnet is properly closed and that the lock is
engaged. If you discover that the bonnet is
not perfectly closed during travel, stop
immediately and close the bonnet in the
correct manner.
18)Perform these operations only when the
car is stationary.

IMPORTANT If the ignition key is turned
to MAR, all the LEDs will stay on for
approximately 4 seconds (check
function).
IMPORTANT If the ignition key is turned
to STOP, the LED for the operating mode
selected will stay on for approximately
2 seconds (LED 3 or 4).
Engine starting always occurs on petrol;
then, depending on the position of the
switch 1 the following occurs:
the switch pressed on the right side
(identified by the symbol
): indicates
petrol operation with activation of the
associated orange LED 3;
the switch pressed on the left side
(identified by the symbolG): indicates
LPG operation with activation of the
associated green LED 4.
If the LPG runs out, the system
automatically switches to petrol: theorange LED 3 comes on and the green
LED 4 indicating LPG operation goes off.
When the vehicle is refuelled with LPG
after a normal start-up on petrol, the fuel
system automatically returns to LPG: the
orange LED 3 switches off and the green
LED 4 for LPG operation switches on.
REFUELLING
12)
LPG
Maximum refuelling capacity (including
reserve): 39 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
20)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.
21)Do not switch between the two
operating modes whilst starting the engine.
22)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
5)The car is equipped with a gaseous LPG
injection system designed specifically for it:
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 a Fiat Dealership.
To prevent damage to the gas system parts
when towing or raising the vehicle, follow the
instructions in the "Towing the vehicle"
paragraph of the Owner Handbook.
6)The system operates at temperatures
ranging between −20°C and 100°C.

7)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.
8)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.
9)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 39 litres (with a tolerance of
2 litres excess). If the value is above 39 litres
(with tolerance of 2 litres excess), contact an
Alfa Romeo Dealership immediately.10)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 on the petrol/LPG switch. 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. In
this event, the performed switching is shown
by the orange (petrol) LED lit and the green
(LPG) LED off on the petrol/LPG witch. When
the above conditions stop, the system
automatically restores the LPG operation;
the orange (petrol) LED turns off and the
green (LPG) LED is lit on the switch. To
achieve the automatic switching described
above, make sure that there is always
enough fuel in the petrol tank.
11)Only use LPG for motor vehicles.
12)The LPG supply system is equipped with
a "consumption" function linked to the LED
display of LPG level on the switch. This
function activates only after a consistent
variation in fuel level has been detected. It is
therefore advisable to fill up with fuel at the
first LPG refuelling to obtain a more
"precise" indication of the level.

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.
