HEADLIGHTS
LIGHT BEAM DIRECTION
The correct orientation of the headlights
is important for the driver's comfort and
safety as well as for all other road users.
This is also covered by a specific rule of
the highway code.
The headlights must be correctly
directed to ensure the best visibility
conditions for all drivers. Contact a Alfa
Romeo Dealership to have the headlights
checked and adjusted, if necessary.
FOG LIGHTS ALIGNMENT(for versions/markets, where provided)
Contact a Alfa Romeo Dealership to have
the headlights checked and adjusted, if
necessary.
ADJUSTING THE HEADLIGHTS ABROAD
The dipped beam headlights are aligned
to comply with the regulations of the
country of purchase. When driving in
countries with a different traffic
direction, to avoid blinding the drivers
travelling in the opposite direction, it is
necessary to cover the areas of the beam
according to the provisions of the
Highway Code of the country you are
driving in.
Alfa DNASYSTEM (Car dynamic
control system)
This device allows, using lever 1
fig. 33 (on the central tunnel), three car
response modes to be selected according
to driving style and road conditions:
d=Dynamic(sports driving mode);
n=Natural(mode for driving in normal
conditions);
a=All Weather(mode for driving in
poor grip conditions, such as rain and
snow).
The lever 1 is of the monostable type. In
other words, it always remains in a
central position.
The selected driving mode is indicated by
the corresponding LED switching on in
the panel and by an indication on the
reconfigurable multifunction display.When “Natural” mode is selected, no
messages or symbols are shown on the
display.
The device acts on the dynamic car
control systems (engine, steering, ESC,
ASR, ELECTRONIC Q2 systems, etc.).
TURNING “Dynamic” MODE ON/OFF
9)
IMPORTANT For versions/markets,
where provided, switching to "Dynamic"
mode is automatically disabled in the
first kilometres in order to guarantee
correct settling of the mechanical
components. If an attempt to activate
the system is made before this limit, the
display will show a dedicated message to
remind the driver that this request
cannot be fulfilled.
Activation
Move lever 1 fig. 33 downwards (to the
letter “d”) and hold in this position for
0.5 seconds until the corresponding LED
lights up or the word “Dynamic” appears
on the display.
When lever 1 fig. 33 is moved to the “d”
position, the activation of “Dynamic”
mode is confirmed by a temporary
variation in the brightness (flashing) of
the instrument panel.

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.

Warning lights on
panelWhat it means What to do
EBD FAILURE
The simultaneous switching on of the
(red) and
(amber) warning lights with the engine on indicates
either an anomaly of the EBD system or that the system is
not available. In this case, the rear wheels may suddenly
lock and the vehicle may swerve when braking sharply.Drive very carefully to the nearest Alfa Romeo Dealership
to have the system inspected immediately.
AIRBAG FAILURE
The warning light switches on when the ignition key is
turned to MAR, but it should switch off after a few seconds.
If the warning light switches on constantly, this indicates a
fault in the airbag system.
22) 23)
SEAT BELTS NOT FASTENED
(for versions/markets, where provided)
The warning light switches on constantly with the vehicle
stationary and the driver’s seat belt not fastened.
The warning light flashes and a buzzer sounds if the car is in
motion and the front seat belts are not correctly fastened.For permanent deactivation of the acoustic signal (buzzer)
of the S.B.R. (Seat Belt Reminder) system contact an Alfa
Romeo Dealership. The system can be reactivated using
the Setup Menu.

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".
SPEED LIMIT EXCEEDED
(for versions/markets, where provided)
The warning light switches on when the car exceeds the
speed limit value set in the Setup Menu (e.g. 120 km/h).
On some versions a message is shown along with a symbol
on the display, and an acoustic signal is emitted.
