Always take due car when braking on
bends, even with the help of the ABS.
The most important advice of all, howev-
er, is this:
Following these instruction you will be in
the best braking condition under all circum-
stances.
IMPORTANTCars fitted with ABS may
only be fitted with the wheel rims, tyres and
brake linings of type and brand approved by
the Manufacturer.
The system is completed by the EBD (Elec-
tronic Brake Distributor) which distributes
the braking action through the control unit
and the ABS system sensors.IMPORTANTIf the battery is run down
the
>andxwarning lights might turn
on when starting the engine and go off af-
ter starting. This should not be considered
as a fault but as a warning that during start-
ing the ABS is not active. The turning off
of the warning lights ensures normal system
operation.
When the ABS cuts in, and
you feel the pulsing on the
pedal, do not lighten the pressure,
but keep the pedal firmly pressed
with no fear; this way you will
stop in the least space possible,
compatibly with the conditions of
the road surface.
WARNING
The car is fitted with an
electronic braking distribu-
tor (EBD). If the
>andxwarn-
ing lights turn on simultaneously
with the engine running, this indi-
cates an EBD system failure; in this
case with sharp braking the rear
wheels might lock too early, with
the possibility of skidding. Driving
extremely carefully, go to the near-
est Alfa Romeo Authorised Service
to have the system checked.
WARNING
The turning on of only the
>warning light with the
engine running normally indicates a
fault to the ABS system only. In this
case the braking system is still ef-
ficient, though without the aid of
the anti-lock device. Under these
conditions performance of the EBD
system may be reduced. In this case
too, you areadvised to go immedi-
ately to the nearest Alfa Romeo
Authorised Service to have the sys-
tem checked over, driving in such
a way as to avoid sharp braking.
WARNING
If the low brake fluid lev-
el
xwarning light turns
on, stop the car immediately and
contact the nearest Alfa Romeo
Authorised Service. Any loss of
fluid from the hydraulic system
will negatively affect the opera-
tion of the braking system be it of
the conventional type or of the
type with ABS.

The stabilising action of the VDC system is
based on the calculations of the system elec-
tronic control unit, which processes the sig-
nals received from the steering wheel rota-
tion sensor, acceleration sensor and rotation
speed sensor of ech wheel.These signals al-
low the control unit to recognise the ma-
noeuvre the driver intends to do when the
steering wheel is turned.
The control unit processes the information
received from the sensors and therefore able
to know the position of the car instant by in-
stant and compare it with the course the dri-
ver would like to follow. In the event of a
discrepancy, in a fraction of a second the
control unit chooses and commands the
most suitable intervention to bring the car
immediately back to the required course:
braking one or more wheels at different in-
tensity and, if necessary, reducing the pow-
er transmitted by the engine.
The corrective actions are modified and
controlled continuously in seeking the course
required by the driver.
The action of the VDC system considerably
enhances the active safety of the car in very
critical situations and it is particularly help-
ful when the grip conditions of the road sur-
face change.CUTTING IN
OF THE VDC SYSTEM
The cutting in of the VDC system is indi-
cated by the flashing of the
áwarning light
on the instrument cluster, to inform the dri-
ver that the car is in critical conditions of sta-
bility and grip.
VDC system failure warning
In the event of a failure the VDC system
disengages automatically and the
áwarn-
ing light on the instrument cluster turns on
glowing steadily, together with the message
on the reconfigurable multifunction display.
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 Authorised Services as soon
as possible.
For the VDC system to
work correctly, the tyres
must be of the same brand and
type on all wheels, in perfect con-
ditions and above all of the speci-
fied type, brand and size.
WARNING

IMPORTANTWhen travelling on snow
with snow chains, it may be helpful to turn
the ASR device off: in fact, in these condi-
tions, slipping of the driving wheels when
moving off makes it possible to obtain bet-
ter drive.
ASR system failure warning
Should a defect arise, the ASR system is
automatically disconnected and the re-con-
figurable multifunction display informs user
about this condition by displaying a dedi-
cated message.
In the event of an ASR system operating
failure, the car behaves in the same way
as a car that is not fitted with this system:
in any case, it is advisable to contact Alfa
Romeo Authorised Services as soon as pos-
sible.
EOBD SYSTEM
The EOBD system (European On Board Di-
agnosis) installed on the car meets Directive
98/69/CE (EURO 3).
This system allows continuous diagnosis
of the components on the car correlated with
emissions; it also alerts the driver, by turn-
ing on the warning light
U(on some ver-
sions together with the message + symbol
on the reconfigurable multifunction display)
on the instrument panel when these com-
ponents are no longer in peak conditions.
The objective is:
– to keep system efficiency under control;
– warn when a fault causes emission lev-
els to increase over the threshold established
by European law;
– warn of the need to replace deteriorat-
ed components.
The system also has a diagnostic connec-
tor that can be interfaced with appropriate
tools, which makes it possible to read the
error codes stored in the control unit, to-
gether with a series of specific parameters
for engine operation and diagnosis.If, turning the ignition key
to MAR, the warning light
Udoes not turn on or if,
while travelling it turns on glow-
ing steadily or flashing together
with the message + symbol on the
reconfigurable multifunction dis-
play, contact Alfa Romeo Autho-
rised Services as soon as possible.
IMPORTANTAfter eliminating the in-
convenience, to check the system com-
pletely, Alfa Romeo Authorised Services are
obliged to run a bench test and, if necessary
road tests which may also call for a long jour-
ney.For correct operation of the
ASR system the tyres must
absolutely be of the same brand
and type on all wheels, in perfect
conditions and, above all, of the
specified type, brand and size.

various radio functions (e.g. storing stations)
before starting to drive.
Reception conditions
Reception conditions change constantly
when driving. Reception may be disturbed
by the presence of mountains, buildings or
bridges particularly when far away from the
station being listened to.
IMPORTANTWhen receiving traffic in-
formation, the volume may be higher than
normal.Care and maintenance
The radio structure ensures long operation
with no need for particular maintenance.
In the event of a fault, contact Authorised
Alfa Romeo Services.
To clean the front panel only use a soft,
antistatic cloth. Cleaning and polishing prod-
ucts might spoil the surface.
Compact Disc
Remember that dirt, marks or distortion on
Compact Discs can cause skipping and poor
sound quality. For top performance condi-
tions, we give the following advice:
– Only use Compact Discs which have the
following brand:
– Carefully clean all Compact Disc of fin-
gerprints and dust using a soft cloth. Sup-
port Compact Discs from the outer circum-
ference and clean from the centre outwards.
INTRODUCTION

STARTING PROCEDURE
IMPORTANTIt is important never to
press the accelerator before 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
gears.
4) Ensure that the electric systems and de-
vices, especially if they absorb high quanti-
ties of energy (e.g. heated rearscreen) are
switched off.
5) Turn the ignition key to the AV Vpo-
sition and release it as soon as the engine
starts.
6) If the engine does not start, return the
key to STOPthen repeat the procedure.
IMPORTANTIf it is difficult to start the
engine do not insist with extended attempts
which may damage the catalyst, but con-
tact Alfa Romeo Authorised Services. The ignition switch is fitted with a safety
device which obliges the driver to return the
key to the STOPposition before repeat-
ing the starting operation if the engine does
not start immediately.
Similarly, when the engine is running, the
device prevents the key being moved from
theMARto the AV Vposition.
STARTING
THE ENGINE
IMPORTANTThe car is fitted with an
electronic engine lock device. If the engine
fails to start, see “The Alfa Romeo CODE sys-
tem”.

We recommend that dur-
ing the initial period you do
not drive to full vehicle
performance (for example exces-
sive acceleration, long journeys at
top speed, hard braking etc.).When the engine is
switched off never leave
the ignition key in the MAR
position to prevent pointless cur-
rent absorption from draining the
battery.
Running the engine in con-
fined areas is extremely
dangerous. The engines consumes
oxygen and produces carbon
monoxide which is a highly toxic
and lethal gas.
