ABS
(on request for versions/markets
where applicable)
The car is fitted with an ABS braking sys-
tem, which prevents the wheels from lock-
ing when braking, makes full use of the grip
and within the limits of the grip available,
keeps the car controllable also in emergency
braking.
When braking a slight pulsing accompa-
nied by noise may be felt on the brake ped-
al due to the action of the ABS system.
This should not be interpreted as a brak-
ing malfunction. It is the signal to the driver
that the ABS has come into action: it is the
warning that the car is travelling at the lim-
it of its grip and therefore the speed should
be adapted to the type of road.
The ABS system is an additional part of the
base braking system; in the event of a fail-
ure it is disabled, leaving the braking sys-
tem in the same conditions as a car without
ABS.
In the case of a failure, the anti-lock action
is no longer present, the braking capacity of
the car is not adversely affected at all. The ABS better exploits
the grip available, but can-
not increase it; caution is
therefore necessary on slippery
surfaces, without taking unneces-
sary risks.
If the ABS cuts in it means
that the limit of the grip is
being reached between the
tyre and the road surface: it is
therefore necessary to slow down
to adapt driving to the grip avail-
able.
In the event of a system
failure, with the turning on
of the
>warning light on
the instrument cluster, have the car
checked immediately by Alfa
Romeo Authorised Services, to be
able to have the system restored
to fully efficient conditions.
If you have never previously used cars fit-
ted with ABS, it is advisable to practice a lit-
tle on a slippery surface, naturally in safe-
ty conditions and in accordance with the lo-
cal Highway Code; you are also advised to
read the following instructions carefully.
The advantage of the ABS over a conven-
tional system is that it makes it possible to ob-
tain the highest degree of handling also when
braking completely under limited grip condi-
tions, preventing the wheels from locking.
However, with the ABS do not expect the
braking distance to always shorten: for ex-
ample, on soft surfaces like gravel or fresh
snow or a slippery surface, the space might
increase.
To better exploit the possibilities of the an-
ti-lock system in the case of need, the ad-
vice given below should be followed.

Always take due care when braking on
bends, even with the help of the ABS.
The most important advice of all, howev-
er, is this:
When the ABS cuts in, and
you feel the pulsing on the
pedal, do not lighten the
pressure, but keep the pedal firm-
ly pressed with no fear; this way
you will stop in the least space
possible, compatibly with the con-
ditions of the road surface.
Following these instructions you will be
in the best braking condition under all cir-
cumstances.
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. The car is fitted with an
electronic braking distribu-
tor (EBD). If the
>andx
warning lights turn on simultane-
ously with the engine running, this
indicates an EBD system failure; in
this case with sharp braking the
rear wheels might lock too early,
with the possibility of skidding. Dri-
ving extremely carefully, go to the
nearest Alfa Romeo Authorised Ser-
vice to have the system checked.
The turning on of only the
>warning light with the
engine running normally in-
dicates a fault to the ABS system
only. In this case the braking sys-
tem is still efficient, though with-
out the aid of the anti-lock device.
Under these conditions perfor-
mance of the EBD system may be
reduced. In this case too, you are
advised to go immediately to the
nearest Alfa Romeo Authorised
Service to have the system checked
over, driving in such a way as to
avoid sharp braking.
If the low brake fluid lev-
el
xwarning light turns
on, stop the car immedi-
ately and contact the nearest Alfa
Romeo Authorised Service. Any
loss of fluid from the hydraulic sys-
tem will negatively affect the op-
eration of the braking system be it
of the conventional type or of the
type with ABS.
If the compact spare
wheel is used, operation of
the ABS system is cut off
and the
>warning light on the in-
strument cluster turns on.
IMPORTANTIf the battery is run down
the
>andxwarning lights might turn on
when starting the engine and go off after
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.

The stabilising action of the 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 each wheel. These signals
allow 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 is
able to know the position of the car instant
by instant and compares it with the course
the driver 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 system considerably en-
hances 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. For the VDC system to
work correctly, the tyres
must be of the same brand
and type on all wheels, in perfect
conditions and above all of the
specified type, brand and size. CUTTING IN
OF THE VDC SYSTEM
The cutting in of the system is indicated by
the flashing of the áwarning light on the
instrument cluster, to inform the driver that
the car is in critical conditions of stability and
grip.
VDC system failure warning
In the event of a failure the system dis-
engages automatically and the
áwarning
light on the instrument cluster turns on glow-
ing steadily, together with the message on
the reconfigurable multifunction display.
In the event of an system failure the car
behaves like a car not fitted with this sys-
tem: in any case it is advisable to contact
Alfa Romeo Authorised Services as soon as
possible.During use of the compact
spare wheel, the VDC sys-
tem continues working. It
should be borne in mind that the
spare wheel is smaller than a nor-
mal tyre, therefore its grip is low-
er than that of the other tyres of
the car.

SWITCHING ON
THE ASR FUNCTION
The ASR function switches on automati-
cally each time the engine is started.
When travelling the ASR can be switched
off and on again pressing switch (A-fig.
151).
When the function is turned off, the in-
strument panel warning light
Vturns on.
If the function is switched off when trav-
elling, it will turn on again automatically the
next time the engine is started.

ASR SYSTEM
(Antislip Regulation)
(on request for versions/
markets where applicable)
The ASR function controls the car drive and
cuts in automatically every time one or both
driving wheels slip.
In slipping conditions, tow different control
systems are activated:
1) if slipping involves both driving wheels,
being caused by excessive power transmit-
ted, the ASR device cuts in reducing the pow-
er transmitted by the engine.
2) if slipping involves only one driving
wheel, the ASR system cuts in automatical-
ly braking the wheel that is slipping, with
an effect similar to that of a self-locking dif-
ferential.The performance of the
system in terms of active
safety should not induce
the driver to take pointless and un-
necessary risks. The style of dri-
ving must in any case be adapted
to the conditions of the road sur-
face, visibility and traffic. Road
surface is always the driver’s re-
sponsibility.
The action of the ASR is particularly help-
ful in the following circumstances:
– slipping of the inner wheel on a bend,
due to the effect of dynamic load changes
or excessive acceleration.
– too much power transmitted to the
wheels also in relation to the conditions of
the road safety.
– acceleration on slippery, snowy or frozen
surfaces.
– in the case of loss of grip on a wet sur-
face (aquaplaning).

ASR system
failure indications
In the event of a fault, the ASR system
switches off automatically and the
Vwarn-
ing light on the instrument cluster turns on,
together with the message on the reconfig-
urable multifunction display.
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.MSR SYSTEM (engine braking
torque control)
The car is fitted with a special system, in-
tegral with the ASR system, that in case of
sudden gear shifting, cuts in providing torque
to the engine thus preventing excessive dri-
ving wheel drive that, specially in poor grip
conditions, can lead to loss of stability. During use of the compact
spare wheel, the ASR func-
tion is cut off and the
V
warning light on the instrument
cluster turns on glowing steadily
together with the message on the
reconfigurable multifunction dis-
play.
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 type, brand and size specified.
IMPORTANTWhen travelling on snowy
roads with snow chains, it may be helpful
to turn the ASR off: in fact, in these condi-
tions, slipping of the driving wheels when
moving off makes it possible to obtain bet-
ter drive.

EOBD SYSTEM
(upon request for versions/
markets where applicable)
The EOBD system (European On Board Di-
agnosis) allows continuous diagnosis of the
components of the car correlated with emis-
sions.
It also alerts the driver, by turning on the
warning light
Uon the instrument panel
(on certain versions together with message
+ symbol on the reconfigurable multifunc-
tion display), when these components are
no longer in peak conditions.
The objective is:
– to keep the system efficiency under con-
trol;
– to warn when a fault causes emissions
levels to increase;
– to warn of the need to replace deterio-
rated 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. This
check can also be carried out by the traffic
police.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.
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 (on some
versions together with the mes-
sage + symbol on the reconfig-
urable multifunction display), con-
tact Alfa Romeo Authorised Ser-
vices as soon as possible.

Care and maintenance
The radio structure ensures long operation
with no need for particular maintenance.
In the event of a fault, contact Alfa Romeo
Authorized 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 Disc can cause skipping. To obtain
optimum playing conditions we give the fol-
lowing advice:
– Only use Compact Discs which have the
following brand:
– Carefully clean all Compact Discs of fin-
gerprints and dust using a soft cloth. Sup-
port Compact Discs from the outer circum-
ference and clean from the centre outwards;
– Never use chemical products for clean-
ing (e.g.: spray cans, antistatic or thinners)
as they might damage the surface of Com-
pact Discs;
– After use, put Compact Discs back in
their container, to avoid marks or scratches
that may cause skipping when playing;
– Do not expose Compact Discs to direct
sunlight, high temperatures or damp for pro-
longed lengths of time to prevent them from
bending;
– Do not stick labels or write on the record-
ed surface of Compact Discs. Too high a volume when
driving can put the driver’s
life at risk and that of oth-
er people. Therefore the volume
should always be adjusted in such
a way that it is always possible to
hear the noises of the surrounding
environment (e.g.: horns, ambu-
lance, police sirens, etc.).

IMPORTANTThe sealing of the tank
may cause light pressurising in the tank. A
little breathing off, while slackening the cap,
is absolutely normal.
After refuelling, turn the cap clockwise and
close the flap.
IMPORTANTFor your safety, make sure
that the fuelling pump nozzle is inserted cor-
rectly into the housing, before starting the
engine.Should it be not possible to open the fuel
flap electrically, use the special cable in the
boot (A-fig. 156) to open it manually. FUEL CAP
The fuel cap (C-fig. 154) is electrically
controlled. To open it, press button (D-fig.
155); the flap can be opened only when
the engine is off.
The fuel cap (A-fig. 154), accessible af-
ter opening the lid (C), is fitted with a catch
to prevent losing it (B) which fastens it to
the lid.
When refuelling, hook the cap to the de-
vice on the inner flap, as illustrated.
Do not put naked flames
or lighted cigarettes near
the fuel filler hole as there
is a danger of fire. Do not bend too
close to the hole either so as not to
breathe in harmful vapours.
If required, replace the fu-
el cap only with a genuine
new one to prevent im-
pairing the petrol vapour system.

Diesel Particulate Filter clogged
When the diesel particulate filter is
clogged, the display shows symbol
h
+ message. In this event keep the engine
running until symbol
hand message
turn off. Reclaiming procedure is controlled auto-
matically by the engine control unit accord-
ing to the filter conditions and the conditions
of use of the car. During reclaiming the fol-
lowing phenomena could take place: idling
slight increase, fan activation, slight smoke
increase, high exhaust temperatures.
These situations shall not be considered as
faults and they do not affect car perfor-
mance and environment.

STARTING PROCEDURE
FOR JTD VERSIONS
1) Make sure the handbrake is engaged.
2) Set the gearshift lever to neutral.
3) Turn the ignition key to MAR. The re-
configurable multifunction display will show
the
mwarning light.
4) Wait for the
mto turn off, which
takes place sooner, the warmer the engine.
With the engine very warm the light might
stay on for such a short time as to pass un-
noticed.
5) Fully depress the clutch pedal.
6) Turn the ignition key to AV Vas soon
as the
mwarning light has gone out.
Waiting too long, makes the warming work
of the glow plugs useless.IMPORTANTThe electric devices that
absorb a high amount of energy (climate
control, rearscreen heating, etc.) are cut off
automatically during starting.
If the engine does not start at the first at-
tempt, move the ignition key to STOPbe-
fore repeating starting.
If starting is difficult (with the Alfa Romeo
CODE system working properly), do not in-
sist with prolonged attempts.
Only use an auxiliary battery if the cause
is due to low battery charge. Never use a
battery charger to start the engine.
WARMING THE ENGINE
– Drive off slowly, at medium revs with-
out accelerating abruptly.
– Do not drive at full performance for the
initial kilometres of the journey. Wait until
the engine coolant temperature reaches 50-
60 °C.
