If the
x
low brake fluid
warning light comes on (to-
gether with the message + symbol
shown by the display), stop the car
immediately and contact the near-
est Alfa Romeo Authorized Ser-
vices. Indeed, any leak of fluid
from the hydraulic system com-
promises the effectiveness of both
the conventional brake system and
the system with antilock system.
WARNING
The turning on of the
>
warning light (together
with the message + symbol shown
by the display) with the engine
running normally indicates an ABS
system fault. In this case the brak-
ing system preserves its effec-
tiveness, without however making
use of the antilock device. Under
these circumstances, the EBD sys-
tem may fail to give top perfor-
mance. In this case, too, you are
recommended to contact Alfa
Romeo Authorized Services imme-
diately, driving in such a way as to
avoid abrupt braking, to have the
system checked.
WARNING
VDC AND ASR
SYSTEMS(where required)VDC SYSTEM (VEHICLE
DYNAMICS CONTROL):
GENERALThe VDC is an electronic vehicle stability
control system which, acting on the torque
and braking the wheels in a differentiated
manner, helps to bring the car back to the
correct course in the event of loss of grip.
While travelling the car is subjected to lat-
eral and longitudinal forces that may be
controlled by the driver up to when the
tyres offer adequate road-holding; when
this falls below the minimum level, the car
starts to deviate from the course required
by the driver.
Above all on rough surfaces (such as cob-
bles, or due to the presence of water, ice
or soil), changes in speed (when accelerat-
ing or braking) and/or course (bends or the
need to avoid obstacles) can cause the tyres
to lose grip.When the sensors detect the conditions
that would lead to skidding, the VDC system
acts on the engine and brakes generating
a stabilising torque.
The system performance
levels, in terms of active
safety, should not induce the dri-
ver to run pointless and unjustified
risks. Driving conduct should al-
ways be suited to the conditions of
the road surface, vision and traf-
fic. The responsibility for road
safety is always and anyway the
vehicle driver’s concern.
The VDC system helps the driver
to keep control of the car in the
event of loss of tyre grip.
The forces induced by the VDC sys-
tem to control the lack of stability
of the car always and anyway de-
pend on the grip between the tyre
and the road surface.

REFUELLING PETROL ENGINESIn order to prevent the vehicle being filled
with leaded petrol, the diameter of the filler
neck is smaller than the nozzle used on
pumps delivering leaded petrol.At low temperatures, the degree of fluid-
ity of fuel oil may become insufficient due
to the formation of paraffins leading to dan-
ger of clogging the fuel oil filter.
Therefore, to avoid inconveniences, sum-
mer and winter fuel oils are normally dis-
tributed depending on the season.
However, during the intermediate season,
characterised by a large difference between
outside temperatures (0°C to 15°C), the
quality of the fuel oil distributed to the
pumps may not be adequate.
In this case, and above all if the use of the
car involves stopping and then starting again
at low temperatures (e.g. mountains),
make sure the car is filled with winter fuel
oil; if not, you are advised to mix the fuel
oil with a DIESEL MIXadditive in the pro-
portions stated on the can, pouring first the
antifreeze and then the fuel oil into the tank.
TheDIESEL MIXantifreeze should be
mixed with the fuel oil before reactions due
to cold take place. Adding it too late will
prove pointless. The anti-pollution devices
present on the vehicle im-
pose the use of four-star
unleaded fuel with an octane num-
ber (R.O.N.) above 95.
Under no circumstances
should conventional leaded
petrol be used, as this
would irreparably damage the cat-
alyst. If the tank is accidentally
filled with leaded fuel, even in
minute quantities, DO NOT START
THE ENGINE. Do not attempt to di-
lute the petrol with lead free fuel.
Drain the entire fuel circuit and
tank.
If the catalyst is not
working properly, harmful
emissions reach the ex-
haust, resulting in environment pol-
lution.The car must be refuelled
only with fuel oil for motor
vehicles, in conformity with
European specification EN590. The
use of other products or mixtures
may damage the engine irrepara-
bly, resulting in invalidation of the
warranty for the damage caused.
If the tank is accidentally filled
with another type of fuel, do not
start the engine but drain the tank.
If the engine has been run even for
a brief period, the tank must be
drained together with the entire
fuel circuit.

PROCEDURE FOR PETROL
ENGINESWARNINGIt is important not to press
the accelerator until the engine has started.
1) Make sure the handbrake is engaged.
2)Move the gear lever to neutral.
3)Fully depress the clutch pedal so that
the starter motor is not forced to crank the
toothed wheels of the gearbox.
4)Ensure that the systems and electrical
devices, especially if they absorb high quan-
tities of energy (e.g. heated rear wind-
screen) are switched off.
5)Turn the ignition to the AV Vposition
and release it as soon as the engine starts.
6)If the engine does not start, return the
key to the STOPposition and repeat the
operation.
WARNINGIf it is difficult to start the en-
gine do not insist with extended attempts
which may damage the catalyzer but con-
tact Alfa Romeo Authorized Services. The ignition switch is fitted with a safety
device which obliges the driver to return the
ignition key to the STOPposition before re-
peating the starting operation if the engine
does not start immediately.
Similarly, when the engine is running, the
device prevents the key being moved from
the MARto the AV Vposition.
STARTING
THE ENGINEWARNINGThe car is fitted with an elec-
tronic engine lock device. If the engine fails
to start see “Alfa Romeo CODE system”.

In addition to the notes
and specifications given be-
low we recommend that,
during the initial period, you do not
drive to full vehicle performance
(for example excessive accelera-
tion, long journeys at top speed,
hard braking, etc.).
To avoid useless con-
sumption of power and
possible draining the bat-
tery, never leave the ignition key
in the MAR position when the en-
gine is not running.
Running the engine in con-
fined areas is extremely
dangerous. The engine consumes
oxygen and produces carbon
monoxide which is a highly toxic
and lethal gas.

WARNINGOn the 2.0 JTS version,
keep the brake pedal pressed when starting
the engine. As the brake pedal stiffens if it
is pressed repeatedly with the engine off. In
this situation, to allow the engine to be
started, it is necessary to increase the pres-
sure exerted on the pedal itself.PROCEDURE FOR JTD VERSIONS1)Make sure the handbrake is engaged.
2)Move the gearshift lever to neutral.
3)Turn the ignition key to the MARpo-
sition. The warning light
m
on the instru-
ment cluster will turn on.
4)Wait for the
m
warning light to go
off, which will depend on how warm the en-
gine is. With the engine very hot the warn-
ing light may stay on for such a short time
that it is not noticed.
5)Fully depress the clutch pedal.
6)Turn the ignition key to AV Vas soon
as the
m
warning light goes off. Waiting
too long would make the glow plug heating
work pointless.WARNINGThe electric devices that ab-
sorb much energy (air conditioner,
rearscreen heating, etc.) are disengaged au-
tomatically during engine starting.
If the engine does not start at the first at-
tempt, move the ignition key back to the
STOPposition before repeating starting.
If starting is difficult (with the Alfa Romeo
CODE system efficient), do not insist with
prolonged attempts.
Only use an auxiliary battery if it is noted
that the cause is due to low charge of the
car’s battery. Never use a battery charger to
start the engine (see “If the battery is flat”
in the chapter “In an emergency”).
WARMING THE ENGINE– Drive off slowly, at medium revs with-
out accelerating abruptly.
– Do not drive at full performance for the
initial kilometers of the journey, Wait until
the engine coolant temperature is between
50 and 60°C.SWITCHING OFF– Release the accelerator pedal and wait
until the engine reaches idle speed.
– Turn the ignition key to the STOPpo-
sition and switch off the engine.
WARNINGAfter a taxing drive it is bet-
ter to allow the engine to “catch its breath”
before turning it off by letting it idle to al-
low the temperature in the engine com-
partment to fall.

Tyres
Tyres should be checked at least every four
4 weeks: if the pressure is too low, fuel con-
sumption increases as the resistance to the
rolling movement of the tyre is higher. In
this state, tyre wear is increased
and vehicle handling suffers which will af-
fect safety.
Unnecessary loads
Do not travel with too much luggage stowed
in the boot. The weight of the vehicle (es-
pecially when driving in town) and its trim
greatly affects consumption and stability.
Luggage/ski rack
Remove luggage or ski racks from the roof
of the vehicle as soon as they are no longer
needed. These accessories reduce the aero-
dynamic penetration of the vehicle and will
increase consumption. When transporting
particularly large objects, use a trailer where
possible.Electrical devices
Use the electric devices for the necessary
time only. The heated rear window, supple-
mentary lights, windscreen wipers, heating
system blower require large amounts of en-
ergy and, increasing the request for power
also increases fuel consumption (up to
+25% when driving in built-up areas).
Air conditioner
The air conditioner is an additional load
which greatly affects the engine leading to
higher consumption (on average up to
+20%). When the temperature outside the
vehicle permits it, use the air vents where
possible.
Spoilers
The use of aerodynamic optional extras
which are not certified for the specific use
on the vehicle, may reduce the aerodynamic
penetration of the vehicle and increase con-
sumption.
STYLE OF DRIVINGStarting
Do not warm the engine when the vehicle
is stationary or at high or low revs: in this
way the engine will warm up gradually in-
creasing consumption and emissions. You
should drive off slowly straight away avoid-
ing high revs so that the engine will warm
up more quickly.
Unnecessary actions
Avoid revving the engine when stopped at
traffic lights or before switching off the en-
gine and avoid doubling the clutch as these
actions have no purpose on modern vehicles
and serve only to increase consumption and
pollution.
Gear selection
As soon as the traffic and road conditions
allow it, shift to a higher gear. Using a lower
gear to liven up acceleration greatly in-
creases consumption. In the same way, im-
proper use of the higher gears will increase
consumption, emissions and wear and tear
on the engine.

3)Fully depress the accelerator pedal and
keep it pressed. The warning light
U
will
come on for eight seconds approximately
and will then go out; now release the ac-
celerator pedal.
4)The warning light
U
begins to flash:
after it has flashed for the same number of
times as the first digit on the code of the
card, press completely and hold down the
accelerator pedal until the warning light
U
comes on (for 4 seconds) and then goes out
again; now release the accelerator pedal.
5)The warning light
U
will begin to
flash: after it has flashed for the same num-
ber of times as the second digit on the code
of the card, press completely and hold down
the accelerator pedal.
6)Repeat this procedure in the same way
for the other digits on the CODE card code.
7)After entering the last figure, keep the
accelerator pedal pressed. The warning light
U
turns on (for four seconds) and then goes
off; now release the accelerator pedal.8)A quick flash of the warning light
U
(for appr. 4 seconds) confirms that the op-
eration has taken place correctly.
9)Start the car turning the ignition key
from theMAR position to the AVV posi-
tion without returning the key to theSTOP
position.
Conversely, if the warning light
U
stays
on, turn the ignition key to STOPand re-
peat the procedure starting from point 1.
WARNINGAfter emergency starting it
is advisable to turn to an Alfa Romeo Au-
thorized Service, because the procedure de-
scribed must be repeated each time the en-
gine is started.
EMERGENCY
STARTINGIf the Alfa Romeo CODE system is not able
to deactivate the engine inhibitor, warning
lights
Y
and
U
remain lit and the engine
cannot be started. To start the engine it is
necessary to follow the emergency starting
procedure.
WARNINGYou are advised to careful-
ly read the entire procedure before carry-
ing it out.
If a mistake is made during the emergency
procedure, the ignition key should be turned
to STOPand the operations must be re-
peated from the start (point 1).
1)Read the 5-figure electronic code on
the CODE card.
2)Turn the ignition key to theMAR po-
sition.

After about 10 minutes, stop and check
the tyre pressure once again; remember to
engage the handbrake.
fig. 15
A0B0336m
fig. 16
A0B0337m
If it is not possible to reach the prescribed
pressure, move the car forwards or back-
wards for about 10 metres, so that the seal-
er is distributed inside the tyre, then repeat
inflation.
If, in spite of the last operation, the pre-
scribed pressure is not achieved, do not
move the vehicle and contact Alfa Romeo
Authorized Services.
Once the correct tyre pressure has been
reached, start driving immediately so that
the sealer is distributed evenly inside the
tyre.
Place the sticker in a posi-
tion where it can be clear-
ly seen by the driver as a notice
that the tyre has been treated with
the quick repairing kit. Drive care-
fully especially in a bend. Do not
overcome 80 km/h. Avoid sudden
acceleration or braking.
WARNING
If the pressure is below
1,3 bars, do not drive any
further; FIX & GO cannot guaran-
tee proper hold because the tyre is
too much damaged. Contact Alfa
Romeo Authorized Services.
Conversely, if at least 1,3 bars are
detected, restore the correct pres-
sure (with the engine running and
the handbrake engaged) and start
driving the car with great care.

WARNINGA battery kept at below
50% of its capacity is damaged by sulpha-
tion, the capacity is reduced and starting
is difficult, there is also more possibility of
freezing (this can occur at –10°C). In the
event of a prolonged stop, refer to “Vehi-
cle inactivity”, in the chapter “Getting the
best out of your car”. – Connect the charger cables to the bat-
tery terminals ensuring that the bias is cor-
rect.
– Turn on the charger.
– After charging turn off the charger be-
fore disconnecting it from the battery.
– Reconnect the battery negative termi-
nal (–).
WARNINGIf the car is fitted with an
alarm system, turn off the alarm with the
remote control and deactivate the system
turning the emergency key to “OFF” (see
