VDC SYSTEM
(Vehicle Dynamics
Control)
The VDC system is an electronic system
controlling the car stability in the event
of tyre grip loss.
The VDC system is therefore particular-
ly useful when grip conditions of the
road surfaces changes.
VDC SYSTEM
INTERVENTION
It is indicated by the blinking of the
warning light
áon the instrument pan-
el, to inform the driver that the car is
in critical stability and grip conditions.
TURNING THE VDC SYSTEM
ON/OFF
The VDC system is automatically acti-
vated when the engine is started. When
travelling, to turn the VDC off press the
ASR/ VDC button on the central console
for 2 seconds fig. 85. Turning off the
VDC will also turn off the ASR. Both func-
tions can be reactivated by pressing the
ASR/VDC button.VDC system deactivation is indicated
by the dedicated message on the dis-
play.
If the VDC has been turned off when
travelling, at next engine start-up it will
turn on again automatically.
A0F0026mfig. 85

The action of the ASR is particularly help-
ful in the following circumstances:
❒slipping of the inner wheel due to
the effect of dynamic load changes
or excessive acceleration;
❒too much power transmitted to the
wheels also in relation to the condi-
tions of the road surface;
❒acceleration on slippery, snowy or
frozen surfaces;
❒in the case of loss of grip on a wet
surface (aquaplaning). This time elapsing without starting, the
system will deactivate automatically by
releasing gradually the brake force.
At releasing, the typical brake disen-
gagement noise indicating that the car
is going to move will be heard.
Failure warnings
System failure is indicated by the dedi-
cated message on the display (see sec-
tion “Warning lights and messages”).
IMPORTANT The Hill Holder system
is not a parking brake. Never get out
of the car without engaging the hand-
brake, switching the engine off and en-
gaging the first gear.

CORRECT USE
OF THE CAR
The performance of the
system, in terms of ac-
tive safety should not induce
the driver to take pointless
and unnecessary risks. The
style of driving must in any
case always be adapted to the
conditions of the road surface,
visibility an traffic. Road safe-
ty is always the driver’s re-
sponsibility.
WARNING
ASR SYSTEM
(AntiSlip Regulation)
This system is an integral part of the VDC
system, it controls car drive and cuts in
automatically every time one or both dri-
ving wheels slip.
According to slipping conditions, two dif-
ferent control systems are activated:
❒if slipping involves both driving
wheels, the ASR function intervenes
reducing the power transmitted by
the engine;
❒if slipping involves only one driving
wheel, the ASR system cuts in au-
tomatically braking the wheel that is
slipping.

Switching the ASR system
on/off
The ASR system switches on automati-
cally each time the instrument panel is
turned on.
When travelling the ASR can be
switched off by pressing briefly the
ASR/VDC button on the central console.
When the ASR is switched off this is
shown by the lighting up of the
ASR/VDC button led and by symbol
V
on the display.
If the ASR is switched off when travel-
ling, it will turn on again automatically
the next time the engine is started.
When travelling on snowy roads with
snow chains, it may be helpful to turn
the ASR off: in fact, in these conditions,
slipping of the driving wheels when mov-
ing off makes it possible to obtain bet-
ter drive.MSR system (engine braking
torque control)
It is an integral part of the ASR system
that in case of sudden gear shifting, cuts
in providing torque to the engine thus
preventing excessive driving wheel dri-
ve that, specially in poor grip conditions,
can lead to loss of stability.
For correct operation of
the ASR system, all
tyres must absolutely be of
the same brand, size and type,
in normal conditions of use and
at the pressure values speci-
fied in paragraph “Wheels” in
section “Technical Specifica-
tions”).
WARNING
Failure warnings
In the event of malfunctioning, the ASR
system is automatically disconnected
and symbol
Vwill be displayed. In this
case contact Alfa Romeo Authorized Ser-
vices as soon as possible.

SOUND SYSTEM
The car is fitted with sound system with
CD or MP3 CD player (where provided).
As concerns sound system operation, re-
fer to the Supplement attached to this
Owner’s Manual.
EOBD SYSTEM
The EOBD system (European On Board
Diagnosis) allows continuous diagnosis
of the components of the car correlat-
ed with emissions.
It also alerts the driver, by turning on the
warning light
Uon the instrument pan-
el (together with the message on the
display) (see section “Warning lights
and messages”), when these compo-
nents are no longer in peak conditions.
The objective is:
❒to keep system efficiency under con-
trol;
❒to warn when a fault causes emis-
sion levels to increase;
❒to warn of the need to replace de-
teriorated components.
The system also has a diagnostic con-
nector that can be interfaced with ap-
propriate tools, which makes it possible
to read the error codes stored in the con-
trol unit, together with a series of spe-
cific parameters for engine operation
and diagnosis.
If when fitting the key
into the ignition device,
the warning light
U
does not turn on or if, while
travelling it turns on glowing
steadily or flashing, contact Al-
fa Romeo Authorized Services
as soon as possible. Warning
light
Uoperation can be
checked by means of special
equipment by traffic agents. Al-
ways comply with the traffic
regulations in force in the coun-
try where you are travelling.
This check can also be carried out by the
traffic police.
IMPORTANTAfter eliminating the
inconvenience, to check the system
completely, Alfa Romeo Authorized Ser-
vices are obliged to run a bench test
and, if necessary, road tests which may
also call for a long journey.

If a failure is indicated, stop the car, turn
the engine off and then clean the sen-
sors. Make sure to be far from possible
ultrasound sources (e.g.: truck pneu-
matic brakes or pneumatic hammers).
If failure cause has been eliminated the
system will resume regular operation
and message + symbol on the display
will turn off.
If the warning light stays on, contact Al-
fa Romeo Authorized Services to have
the system inspected, although the sys-
tem keeps on working. If the failure de-
tected does not impair system operation,
the system keeps on working and fail-
ure is stored in order to be then detect-
ed by Alfa Romeo Authorized Services
at next inspection.GENERAL WARNINGS
When parking, take the utmost care to
obstacles that may be set above or un-
der the sensors. Objects set close to the
car, under certain circumstances are not
detected and could therefore cause dam-
ages to the car or be damaged.
Indications sent by the sensors can be
altered by dirt, snow or ice deposited on
the sensors or by ultrasound systems
(e.g.: truck pneumatic brakes or pneu-
matic hammers) set nearby the car.
TOWING TRAILERS
Sensors are reactivated automatically
when removing the trailer cable plug.
FAILURE INDICATIONS
The system control unit checks every
system component each time the key is
fitted into the ignition device. Sensors
and relevant electrical connections are
then constantly monitored during sys-
tem operation.
Sensor failure is indicated by message
+ symbol on the display (see section
“Warning lights and messages”).
Sensors operation is de-
activated automatically
when the trailer electric
cable plug is fitted into the car
tow hook socket.

DIESEL ENGINES
If the outside temperature is very low,
the diesel thickens due to the formation
of paraffin and could clog the diesel fu-
el filter.
In order to avoid these problems, dif-
ferent types of diesel are distributed ac-
cording to the season: summer type,
winter type arctic type (mountains/cold
areas).
If refuelling with diesel fuel not suitable
for the current temperature, mix diesel
fuel with DIESEL MIXadditive in the
proportions stated on the can, putting
first the antifreeze in the tank and then
the diesel fuel.
DIESEL MIXshall be added to diesel
fuel before the due to cold take place.
Adding it later will be worthless.
AT THE FILLING
STATION
PETROL ENGINES
Use only unleaded petrol. To prevent er-
rors, the diameter of the fuel tank filler
is too small to introduce a lead petrol
pump filler. Use petrol with a rated oc-
tane number (R.O.N.) not lower than
95.
IMPORTANTAn inefficient catalyst
leads to harmful exhaust emissions, thus
contributing to air pollution.
IMPORTANT Never use leaded
petrol, even in small amount or in an
emergency, as this would damage the
catalyst beyond repair.
The car must only be
filled with diesel fuel for
motor vehicles, in com-
pliance with European Standard
EN590. The use of other prod-
ucts or mixtures may irrepara-
bly damage the engine with in-
validation of the warranty due
to the damage caused. In the
event of accidentally filling with
another type of fuel, do not
start the engine and empty the
tank. If the engine has been run
even for only a very short time,
in addition to the tank, it is al-
so necessary to drain out the
whole fuel circuit.

FUEL FILLER CAP
The fuel tank lid can only be opened
with doors unlocked and engine
switched off.
To open the fuel filler cap, operate as
shown by the arrow infig. 87.
The fuel filler cap A-fig. 88 is fitted
with an antiloss device Bwhich fastens
it to the flap Cso it cannot be mislaid.
A0F0159mfig. 87A0F0160mfig. 88
Do not put naked
flames or lighted ciga-
rettes near the fuel filler hole
as there is danger of fire. Do
not bend too close to the hole
either so as not to breathe in
harmful vapours.
WARNING
When refuelling, position the cap on the
device inside the flap as shown in the
figure.
IMPORTANTThe sealing of the tank
may cause light pressurising in the tank.
A little breathing off, while slackening
the cap, is absolutely normal.

The devices for curtailing diesel fuel en-
gine emissions are the following:
❒oxidising catalytic converter;
❒exhaust gas recirculation system
(E.G.R.);
❒diesel particulate filter (DPF).
PROTECTING THE
ENVIRONMENT
The devices for curtailing petrol engine
emissions are the following:
❒three-way catalytic converter;
❒Lambda sensors;
❒fuel evaporation system.
In addition, do not let the engine run,
even for a test, with one or more spark
plugs disconnected.
During normal service
the diesel particulate
filter (DPF) reaches high tem-
peratures. Do not therefore
park the car over inflammable
materials (grass, dry leaves,
pine needles, etc.): fire hazard.
