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.

CORRECT USE OF THE CAR
171
Never push, tow or coast
start the car. This could
cause fuel to flow into the
catalyst damaging it irreversibly.
Remember that the en-
gine brake and power
steering are not opera-
tional until the engine is started,
therefore, much greater effort than
usual is needed on the brake ped-
al and steering wheel. For cars with turbocharg-
er in particular, but for all
cars in general, sharp ac-
celerating should be avoided before
switching the engine off.
A “kick” on the accelerator
serves no purpose, consumes fuel
pointlessly and may cause serious
damage to the turbocharger im-
peller bearings.
EMERGENCY STARTING
If the Alfa Romeo CODE system does not
recognise the code transmitted by the igni-
tion key (warning light
Yon the instru-
ment cluster glowing on steadily) emer-
gency starting may be carried out using the
code of the CODE card.
For the correct procedure see the chapter
“In an emergency”.
IMPORTANTIf the engine turns off with
the car on the move, the next time it is start-
ed, the Alfa Romeo CODE warning light may
turn on(
Y). In this case, check that switch-
ing off and starting the engine again with
the car stationary, the warning light stays
off. If not, contact Alfa Romeo Authorised
Services.
ENGINE 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.
IMPORTANTAfter a tiring journey it is
advisable to let the engine “get its breath
back” allowing it to idle a while to lower the
temperature in the engine compartment.

CORRECT USE OF THE CAR
172
Never leave children un-
attended in the car. Al-
ways remove the ignition
key when leaving the car and take
it with you.To avoid useless con-
sumption of power and
possible draining of the
battery, never leave the ignition
key in the MAR position when the
engine is not running.
PARKING
When the car is parked, proceed as fol-
lows:
– Switch off the engine.
– Engage the handbrake.
– Engage first gear if the car is faced up-
hill or reverse if the car is facing downhill.
– Turn the front wheels so that the car will
immediately come to a halt if the handbrake
slips.
REDUCING
RUNNING COSTS
AND ENVIRONMENT
POLLUTION
By following a few simple guidelines, it
is possible to save car running costs and re-
duce harmful emissions.
GENERAL CONSIDERATIONS
Car maintenance
To take care of the car maintenance have
the checks and adjustments carried out in
accordance with the “Scheduled Mainte-
nance Programme”.
Tyres
Check the pressure of the tyres routinely
at an interval of no more than 4 weeks: if
the pressure is too low consumption levels
increase as resistance to rolling is higher.
Useless loads
Never travel with an overload in the boot.
The weight of the car (especially in urban
traffic), and its geometry heavily affect con-
sumption levels and stability.Electric services
Use electric devices only for the amount of
time needed. Rearscreen heating, addition-
al headlights, windscreen wipers and heater
fan need a considerable amount of energy,
therefore increasing the requirement of cur-
rent increases fuel consumption (up to
+25% in the urban cycle).
Climate control system
The climate control system is a further load
bearing heavily on the engine inducing high-
er consumption levels(up to +20% on av-
erage). Outside temperature permitting,
preferably use the air vents.
Aerodynamic items
The use of non-certified aerodynamic items
may adversely affect air drag and con-
sumption levels.

CORRECT USE OF THE CAR
177
It is necessary therefore to limit their use
to the purposes for which they are certified.
IMPORTANTWhen winter tyres are
used with a maximum speed index below
the one that can be reached by the car (in-
creased by 5%), place a notice in the pas-
senger’s compartment, plainly in the driver’s
view, which states the maximum permissi-
ble speed of the winter tyres (as per EC Di-
rective).
Fit the same type of tyre on all four wheels
(brand and profile) to ensure higher driving
safety when braking and good handling.
Remember that it is inappropriate to
change the direction of rotation of tyres.WINTER TYRES
These tyres are specially designed for dri-
ving on snow and ice, to be fitted in re-
placement of those fitted on the car.
Use winter tyres of the same size as nor-
mal tyres provided on the car.
Alfa Romeo Authorised Services will be
pleased to advise you on the choice of the
tyre most suited to the use the Customer in-
tends to make of it.
For the type of tyre to be used, inflation
pressures and specifications of winter tyres,
follow the instructions given in the “Tech-
nical Specifications” chapter.
The winter features of these tyres are re-
duced considerably when the tread depth
is below 4 mm. In this case, they should be
replaced.
Due to the winter features, under normal
conditions of use or long motorway jour-
neys, the performance of these tyres is low-
er than that of normal tyres.
SNOW CHAINS
Use of snow chains should be in compli-
ance with local regulations.
For 1.8 T. SPARK, 2.0 JTS and 1.9
JTD versions, tyre 195/60 R15 can be
fitted with chains (use snow chains with re-
duced size with max protrusion beyond the
tyre profile of 12 mm). Tyres 205/60 R15
- 205/55 R16 - 205/55 ZR16 - 215/45
R17 - 215/45 ZR17 - 225/40 ZR18 can-
not be fitted with snow chains.
For 3.2
V6version, only use spider type
chains on tyres 215/45 R17” and
215/45 ZR 17”. Tyres 225/45 ZR17 -
225/40 ZR18 cannot be fitted with snow
chains.
Lineaccessori Alfa Romeo provides SPIKES
SPIDER COMPACT chains (model: 17003
compact) with 9 spikes, 16 mm adjustable
length and 17 inch wheel cap adapter.
Snow chains should only be applied to the
drive wheels (front).
Before purchasing or using snow chains,
you are recommended to contact Alfa
Romeo Authorised Services.
Check the tensions of the chain after the
first few metres have been driven.

CORRECT USE OF THE CAR
178
Keep your speed
down when snow
chains are fitted.
Do not exceed 50 km/h. Avoid
potholes, steps and pavements and
avoid also to drive for long dis-
tances on roads not covered with
snow to prevent damaging the car
and the roadbed.
CAR INACTIVITY
If the car is to be left inactive for long pe-
riods, the following precautions should be
noted:
– House the car under cover in a dry and
possibly ventilated place.
– Engage a gear.
– Check that the handbrake is not en-
gaged.
– Clean and protect the paintwork by pro-
tective wax.
– Clean and protect the metal polished
parts with marketed products.
– Cover the rubber windscreen and
rearscreen wiper blades with talcum powder
and raise them off the glass.
– Open the windows slightly.
– Inflate the tyres to a pressure of 0.5 bars
above normal. If possible rest the tyres on
wooden planks and periodically check the
pressure.
– Do not turn on the electronic alarm sys-
tem.– Disconnect the battery negative termi-
nal from the battery and check the battery
charge. This check should be repeated
every three months during stowage.
Charge the battery if the indicator (where
provided) shows a dark colour in the central
green area.
– Do not empty the engine cooling sys-
tem.
– Cover the car with a fabric or perforat-
ed plastic cover. Do not use compact plas-
tic covers which prevent the humidity on the
surface of the car from evaporating. Snow chains cannot be
fitted to the space-saver
spare wheel. So, if a front
(drive) wheel is punctured and
chains are needed, a rear wheel
should be fitted to the front of the
car (adjust tyre pressure to the
specified value as soon as possi-
ble) and the space-saver spare
wheel should be fitted to the rear.
This way with two normal drive
wheels, snow chains can be fitted
to them to solve an emergency.
Deactivate the ASR sys-
tem when snow chains are
fitted. Press the ASR-OFF
button, button led turned on.
