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.

GETTING TO KNOW YOUR CAR

no messages or symbols are shown on
the display.
The device also acts on the dynamic car
control systems (engine, steering, ESC
system, instrument panel).
TURNING “Dynamic” MODE ON/OFF
4)
Activation
Move lever 1 upwards (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.
Deactivation
Mover the lever 1 to the "Natural"
position.
1.4 Turbo MultiAir versions
Selecting the “Dynamic” operation mode,
the turbocharger overboost feature is
enabled. The engine management control
unit allows - in relation to the position of
the accelerator pedal and for a limited
time - maximum pressure levels to be
reached inside the turbocharger, with a
consequent increase in engine torque
with respect to that which is normally
possible.
This function is particularly useful
whenever maximum performance is
required for a short time (e.g. when
overtaking).
IMPORTANT During acceleration, when
the “Dynamic” function is used the
steering may shudder, which is typical of
a sports setting.
TURNING “All Weather” MODE ON/OFF
Activation
Move lever 1 downwards (to the letter
“a”) and hold in this position for
0.5 seconds until the corresponding LED
lights up or the word “All Weather”
appears on the display.
Deactivation
To deactivate “All Weather” mode (and
return to “Natural”), carry out the same
procedure described for “Dynamic” mode,
but move lever 1 to “a”.
IMPORTANT
4)"FAST" VERSION: Considering the high
levels of vehicle performance, it is
recommended to not use the "Dynamic"
mode when driving the first kilometres with
the vehicle in order to provide the
mechanical components with the necessary
running-in period.
DYNAMIC SUSPENSION (active
shock absorber system)
This system interacts with the “Alfa DNA”
system. The “Alfa DNA” system lever
allows you to choose three different
driving settings depending on the route
type and on the road surface (see
paragraph “Alfa DNA system”).
In “Natural” and “All Weather” operating
mode, the active shock absorbers adjust
the car suspension to suit the route type
and the driving stresses, thus
considerably improving driving comfort
in particular on rough terrain.
The "Dynamic" operating mode produces
a sports driving setting characterised by
more responsive acceleration and
greater effort on the steering wheel to
give a sporty feeling. The shock absorber
damping action is also adjusted and
divided, to guarantee higher precision
and reactivity of the car, while
maintaining a good comfort level.
The driver will notice that the vehicle is
more precise when cornering and quicker
in changing direction.

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.

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.

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.

(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 begins to flash (on some versions, the
symbol and a message appear on the display) to indicate
a gearbox fault.
On the display, together with the warning light, the
following messages can be shown:
“Check transmission” message;
“Gear not available” message;
“Manual mode not available” message;
“Automatic mode not available” message;
“Required manoeuvre incompatibility” message;
“Clutch overheating” message.

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
(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.
13)
DEGRADED ENGINE OIL (where provided)
The warning light will turn on flashing and, on some versions, with a specific message
on the display.
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. On some versions, the
display shows a dedicated message together with 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.
