GETTING TO KNOW YOUR CAR
178
Braking on corners always requires the ut-
most caution, even with the help of the ABS.
The most important piece of advice, how-
ever, is the following:Following these instructions you will be
in a condition to obtain peak braking per-
formance at all times.
WARNINGCars fitted with ABS must
only be fitted with wheel rims, tyres and
brake linings of the type and brand approved
by the Manufacturer.
The braking system is completed by the
electronic control braking distribution system
called EBD(Electronic Braking Force Dis-
tributor) which distributes the braking action
through the ABSsystem control unit and
sensors.
In the event of a system
fault, with lighting up of
the
>
warning light on the instru-
ment cluster (together with the
message + symbol shown by the
display), have the vehicle checked
immediately by Alfa Romeo Au-
thorized Services, driving slowly
to be able to regain full system
performance.
WARNING
When the ABS cuts in and
you feel the pedal pulse, do
not reduce the pressure, but keep
the brake pedal firmly pressed
with no fear; this way you will
stop in the shortest possible space,
compatibly with the conditions of
the road surface.
WARNING
The car is fitted with an
electronic brake distributor
(EBD). If the
>
and
x
warning
lights, where required, come on at
the same time (together with the
message + symbol shown by the
display) when the engine is run-
ning, there is an EBD system fault;
in this case, violent braking may
lock the rear wheels too early, with
the possibility of skidding. Drive
extremely carefully to the nearest
Alfa Romeo Authorized Services to
have the system checked over.
WARNING
In order to be able to exploit as far as pos-
sible the possibility of the antilock system
in the case of need, it is wise to follow a few
pieces of advice:
The ABS exploits the avail-
able grip in full, but it can-
not increase it; therefore, caution
is required on slippery surfaces,
without running unnecessary risks.
WARNING
If the ABS cuts in, it means
that the grip limit between
the tyres and the road surface has
been reached: it is necessary to
slow down and adapt driving to
the grip available.
WARNING

If the
x
low brake fluid
warning light comes on (to-
gether with the message + symbol
shown by the display), stop the car
immediately and contact the near-
est Alfa Romeo Authorized Ser-
vices. Indeed, any leak of fluid
from the hydraulic system com-
promises the effectiveness of both
the conventional brake system and
the system with antilock system.
WARNING
The turning on of the
>
warning light (together
with the message + symbol shown
by the display) with the engine
running normally indicates an ABS
system fault. In this case the brak-
ing system preserves its effec-
tiveness, without however making
use of the antilock device. Under
these circumstances, the EBD sys-
tem may fail to give top perfor-
mance. In this case, too, you are
recommended to contact Alfa
Romeo Authorized Services imme-
diately, driving in such a way as to
avoid abrupt braking, to have the
system checked.
WARNING
VDC AND ASR
SYSTEMS(where required)VDC SYSTEM (VEHICLE
DYNAMICS CONTROL):
GENERALThe VDC is an electronic vehicle stability
control system which, acting on the torque
and braking the wheels in a differentiated
manner, helps to bring the car back to the
correct course in the event of loss of grip.
While travelling the car is subjected to lat-
eral and longitudinal forces that may be
controlled by the driver up to when the
tyres offer adequate road-holding; when
this falls below the minimum level, the car
starts to deviate from the course required
by the driver.
Above all on rough surfaces (such as cob-
bles, or due to the presence of water, ice
or soil), changes in speed (when accelerat-
ing or braking) and/or course (bends or the
need to avoid obstacles) can cause the tyres
to lose grip.When the sensors detect the conditions
that would lead to skidding, the VDC system
acts on the engine and brakes generating
a stabilising torque.
The system performance
levels, in terms of active
safety, should not induce the dri-
ver to run pointless and unjustified
risks. Driving conduct should al-
ways be suited to the conditions of
the road surface, vision and traf-
fic. The responsibility for road
safety is always and anyway the
vehicle driver’s concern.
The VDC system helps the driver
to keep control of the car in the
event of loss of tyre grip.
The forces induced by the VDC sys-
tem to control the lack of stability
of the car always and anyway de-
pend on the grip between the tyre
and the road surface.

ASR FUNCTION (ANTISLIP
REGULATION): GENERALThe ASR system integrates the VDC sys-
tem controlling the vehicle drive and com-
ing into operation automatically each time
one or both driving wheels skid.
Two different control systems are activated,
depending on the skidding conditions:
– If skidding concerns both driving wheels,
because it is caused by the excessive power
transmitted, the ASR system cuts in reduc-
ing the power transmitted by the engine.
– If skidding concerns only one driving
wheel, the ASR system cuts in automatically
braking the skidding wheel, with an effect
similar to that of a self-locking differential.The action of the ASR system is particularly
helpful under the following conditions:
– Skidding of the inner wheel on a bend,
due to the effect of the dynamic changes of
the load or over-accelerating.
– Excessive power transmitted to the
wheels, also in relation to the conditions of
the road surface.
– Acceleration on slippery, snowy or icy
surfaces.
– In the case of loss of grip on a wet sur-
face (aquaplaning).
CUTTING IN OF THE VDC
SYSTEMThe cutting in of the VDC system is indi-
cated by the flashing of the warning lightá
on the instrument cluster, to inform the
driver that the car is in critical conditions of
stability and grip.
TURNING ON THE ASR
FUNCTIONThe ASR function turns on automatically
each time the engine is started.
When travelling it is possible to switch the
system off and on again pressing the switch
(A-fig. 171
) on the centre console.
Function disconnection is shown by the led
on the ASR button being turned on. If the
function is turned off while travelling, it will
turn on again automatically the next time
the engine is started.
WARNING When driving on snow, with
snow chains fitted, if may be helpful to switch
off the ASR function: in these conditions in
fact, skidding of the driving wheels when
moving off helps to obtain better traction.

CORRECT USE OF THE CAR
189
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.

DRIVING ON SNOW AND ICEHere are few suggestions for driving in
these conditions:
– Keep your speed down.
– On a snowy road, fit winter tyres or
snow chains; see the related paragraphs in
this section.
– Use exhaust brake where possible and
avoid abrupt braking.
– Avoid abrupt acceleration and changes
of direction.
– During cold weather even apparently dry
roads may be covered with occasional
patches of ice. Pay great attention therefore
when driving on roads which are in the
shade, or where rocks or trees line the road
and on which ice may persist.
– Keep further back from the vehicle in
front.
DRIVING WITH ABSThe ABS is a part of the braking system
which essentially offers two advantages:
1)It prevents wheel lock-up and conse-
quent skidding in emergency stops, partic-
ularly when the road does not offer much
grip;
2)It makes it possible to brake and steer
at the same time so you can avoid unex-
pected obstacles and direct the car where
you want while braking. The extent to which
this can be done will depend on the physi-
cal limits of the tyre’s sideways grip.
To make the most of the ABS:
– In emergency braking or when grip is
low, a slight pulsing can be felt on the brake
pedal: this means that the ABS has come
into action. Do not release the pedal, but
continue pressing it to give continuity to the
braking action.
– The ABS prevents the wheels from lock-
ing but it does not increase the physical lim-
its of grip between the asphalt and the road.
Therefore, also with a car fitted with ABS,
keep within a safety distance from the ve-
hicle in front and limit speed when ap-
proaching bends.
The ABS serves to increase car controlla-
bilty not to go faster.
REDUCING RUNNING
COSTS AND
ENVIRONMENT
POLLUTIONSome suggestions which may help you to
keep the running costs of your vehicle down
and lower the amount of toxic emissions re-
leased into the atmosphere are given below.GENERAL CONSIDERATIONSVehicle maintenance
The overalll state of the vehicle is an im-
portant factor which has a marked influence
over fuel consumption and driving comfort
and on the life span of your vehicle. For this
reason care should be taken to maintain
your vehicle by carrying out the necessary
checks and regulations in accordance with
specifications given in the “Scheduled Main-
tenance Programme” (see sections... spark
plugs, air cleaner, timing).
