Before lifting the bonnet,
make sure that the wind-
screen wiper arms are not raised
from the windscreen.
WARNING
DANGER-SERIOUS INJURY.
When carrying out checks
or maintenance operations in the
engine compartment, take special
care not to bump the head on the
raised bonnet.
WARNING
If checks need to be carried
out in the engine compart-
ment when the engine is still
warm, keep away from the fan as
it could start up even when the key
is removed from the ignition. Wait
until the engine cools down.
WARNING
Scarves, ties and loose
clothing may be caught in
the moving parts.
WARNING
To close:
– lower the bonnet to approx. 20 cm from
the engine compartment, then let it drop.
Try lifting it to make sure that it is shut com-
pletely and not simply caught in the safety
position.
If the bonnet does not close properly, do
not push it down but open it again and re-
peat the above procedure.
For safety reasons the
bonnet shall always be
perfectly closed when travelling.
Always check for proper bonnet
locking. If the bonnet is left inad-
vertently open, stop the car im-
mediately and close the bonnet.

EOBD SYSTEMThe EOBD (European On Board Diagnosis)
system fitted in the car conforms with the
98/69/EC (EURO 3) Directive and the
2001/1/EC Directive, level B (EURO4) for
2.0 JTS, 2.0 JTS Selespeed and JTD 20V
Multijet versions.
This system continuously monitors the
components of the vehicle related to emis-
sions; it also indicates, when the warning
light
U
comes on on the instrument panel
(together with the message + symbol
shown by the display) that the components
in question are in poor conditions.
The objective is the following:
– to keep under control the efficiency of
the system;
– to indicate when a malfunction causes
an increase in the emissions beyond the
threshold established by European regula-
tions;
– to indicate the need to replace the de-
teriorated components.
The system also has a diagnostic connec-
tor, which can be interfaced with adequate in-
struments, that enables the error codes stored
in the control unit to be read, together with
a series of specific parameters concerning the
operation and diagnosis of the engine.This check can also be made by the traf-
fic control agents.
If, when the ignition key
is turned to MAR, the
U
warning light does not
come on or if, when driving, it
lights up and emits a fixed light or
a flashing one (together with the
message + symbol shown by the
display), contact an Alfa Romeo
Authorized Service Station as soon
as possible. The operation of the
U
warning light can also be
checked by means of special equip-
ment available to the traffic con-
trol officers. Comply with the reg-
ulations in force in country where
you drive your car.
WARNINGAfter the problem has beel
resolved, to completely check the system,
the Alfa Romeo Authorized Services must
carry out tests on a test bench and, if nec-
essary, road tests that could be long.
WARNING LIGHT ON
INSTRUMENT PANELWhen the ignition key is turned to MAR,
the dial warning light
á
comes on but must
go out after a few seconds.
If the warning light does not go out, or if it
stays on (together with the message + sym-
bol on the display and the coming on of the
ASR button led) when the vehicle is running,
contact Alfa Romeo Authorized Services.
The flashing of the warning lamp when the
vehicle is running indicates the actuation of
the VDC system.
VDC system failure warning
In the event of a failure the VDC system
disengages automatically and the
á
warn-
ing light on the instrument cluster turns on
glowing steadily (together with the message
+ symbol shown on the display and the com-
ing on of the ASR button led).
In the event of a VDC system failure the
car behaves like a vehicle not fitted with this
system: in any case it is advisable to con-
tact Alfa Romeo Authorized Services as soon
as possible.

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.

CORRECT USE OF THE CAR
191
EMERGENCY STARTINGIf the Alfa Romeo CODE system does not
recognise the code transmitted by the igni-
tion key (Alfa Romeo CODE
Y
warning
light on the instrument cluster on glowing
steadily) emergency starting may be carried
out using the code of the CODE card.
For the correct procedure see the chapter
“In an emergency”.
PARKINGWhen the vehicle is parked, proceed as fol-
lows:
– Switch off the engine.
– Engage the handbrake.
– Engage first gear if the car is facing up-
hill or reverse if the car is facing downhill.
– Turn the front wheels so that the car will
immediately come to a half if the handbrake
slips. Starting by pushing, tow-
ing or running downhill
must absolutely be
avoided. These manoeuvres may
cause fuel to flow into the catalyst
and damage it irreparably.
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.
For vehicles equipped
with turbocharger in par-
ticular and for other vehi-
cles in general, revving the engine
before switching off should be
avoided.
Revving the engine serves no pur-
pose and consumes fuel for no rea-
son. It may also cause damage to
the bearings on the rotor of the
turbocharger.
WARNINGIf the engine turns off with
the car on the move, the next time it is
started, the Alfa Romeo CODE warning lightY
may turn on. In this case, check that
switching off and starting the engine again
with the car stationary, the warning light
stays off. If not, contact Alfa Romeo Au-
thorized Services.
Remember that the servo-
brake and power steering
are not activated until the engine
is started, therefore considerably
greater effort is required on the
brake pedal and steering wheel.
WARNING
Never leave children unat-
tended in the car. Always
remove the key from the ignition
when leaving the car and take it
with you.

DRIVING IN THE RAINRain and wet roads can be dangerous.
If the road is wet, the traction between
wheel and asphalt is greatly reduced, thus
increasing the stopping distance and de-
creasing road holding.
Here are few suggestions in the case of
rain:
– Reduce speed and keep further back
from the vehicle in front.
– If it is raining particularly heavily, visi-
bility is also reduced. In these cases, switch
on the dipped headlights even if it is still day-
light so you can be seen more easily.
– Do not drive through puddles at speed
and hold on tightly to the wheel if you do: a
puddle taken at high speed might cause you
to lose control of the car (“aquaplaning”).
– Position the ventilation controls for
demisting (see chapter “Getting to know
your car”), to prevent visibility from wors-
ening.
– Routinely check the conditions of the
windscreen wiper blades.
DRIVING IN THE FOG– If fog is very thick, avoid travelling
where possible. If travelling with mist,
ground fog or the possibility of fog banks:
– Drive at moderate speed.
– Also in the day turn on the dipped-beam
headlights, rear fog guards and front fog
lights. Do not use the main beam headlights.
WARNINGOn stretches of road with
good visibility, switch off your rear foglights;
the brightness of these lights could annoy
the people travelling in the cars behind.
– Remember that fog also involves wet
asphalt, thus greater difficulty in all types of
manoeuvres and longer stopping distances.
– Keep well away from the vehicle in
front.
– Where possible avoid sudden changes
in speed.
– Possibly avoid overtaking other vehicles.
– If the vehicle is forced to stop (faults,
impossibility to continue due to poor visi-
bility, etc.), firstly try to pull off the road.
Then turn on the hazard warning lights and,
if possible the dipped beam headlights. Ry-
thmically sound the horn if you note another
car coming.
MOUNTAIN DRIVING– When driving downhill, use the engine
braking by engaging a low gear, to prevent
the brakes from overheating.
– Never coast downhill with the engine off
or in neutral and especially not with the ig-
nition key removed.
– Drive at moderate speed and avoid “cut-
ting” corners.
– Remember that overtaking up hill is
slower and therefore requires a greater
length of clear road. If you are being over-
taken on a hill, move over to enable the
other vehicle to pass in safety.
