VDC SYSTEM
(Vehicle Dynamics Control)
The VDC is an electronic system that con-
trols vehicle stability, intervening on the dri-
ving torque and braking the wheels in a dif-
ferentiated manner, in the lack of grip, it
helps to bring the car back to the correct
direction.
When travelling the car is subjected to lat-
eral and longitudinal forces which can be
controlled by the driver as long as the tyres
offer adequate roadholding; when this falls
below the minimum level, the car begins
to divert from the course required by the dri-
ver.
Especially when travelling on an uneven
surface (such as paving, or due to the pres-
ence of water, ice or soil), changes in speed
(acceleration or braking) and/or course
(bends or the need to avoid obstacles) may
cause the tyres to lose grip.
When the sensors detect the conditions
that would lead to skidding, the VDC system
intervenes on the engine and on the brakes
producing a stabilising torque.
HOW THE VDC
SYSTEM WORKS
The VDC system is engaged automatical-
ly when the car is started and cannot be
switched off.
The basic components of the VDC system
are:
– an electronic control unit that process-
es the signals received from the various sen-
sors and brings about the most appropriate
strategy;
– a sensor that detects the position of the
steering wheel;
– four sensors that detect the turning
speed of each wheel;
– a sensor that detects rotation of the car
around its vertical axis;
– a sensor that detects lateral acceleration
(centrifugal force).
The heart of the VDC system is the VDC
control unit, which with the data supplied
by the sensors installed on the car calculates
the centrifugal forces generated when the
car is cornering. The yawing sensor, which
originates from the aeronautical industry, de-
tects the rotations of the car around its own
vertical axis. The centrifugal forces gener-
ated when the car is cornering are detect-
ed by a highly sensitive lateral acceleration
sensor. The VDC system helps the driver to keep
the car under control in the event of a loss
of tyre grip.
The forced induced by the VDC system to
control the loss of vehicle stability always
depend on the grip between the tyre and
the road surface.
The performance of the
system, in terms of active
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, vis-
ibility and traffic. The responsibil-
ity for road safety is always and
in any case the driver’s.

SAFE DRIVING
In designing your Alfa 147 GTA, Al-
fa Romeo has worked thoroughly to achieve
a vehicle able to offer top levels of safety to
its passengers. However, the behaviour of
the driver is still a decisive factor for road
safety.
Below you will find a few simple rules for
travelling safely under different conditions.
You are certainly familiar with many of them
but it is still helpful to read them all care-
fully.
BEFORE DRIVING OFF
– Make sure the lights and headlights are
working properly.
– Adjust the seat, steering wheel and rear-
view mirrors, in order to obtain a correct po-
sition for driving.
– Carefully adjust the headrests so that
the head and not the neck rests on them.
Check that nothing (mats etc.) can get un-
der the foot pedals.– Make sure that any child restraint sys-
tems (seats, cradles, etc.) are correctly fas-
tened on the rear seat.
– Place any objects in the boot with care
to prevent abrupt braking from throwing
them forwards.
– Avoid heavy meals before a journey. A
light meal will help to keep reflexes ready.
Above all avoid alcohol.
Routinely remember to check:
– tyre pressure and conditions;
– engine oil level;
– engine coolant fluid level and system
conditions;
– brake fluid level;
– power steering oil level;
– windscreen washer fluid level.
WHEN TRAVELLING
– The first rule for safe driving is care.
– Care also means being able to predict
the actions of other road users.
– Strictly respect the traffic regulations in
all countries, especially the speed limits.
– Ensure that both yourself and your pas-
sengers are wearing their seat belts, that
children are carried with the appropriate
seats and that any animals are in appropri-
ate compartments.
– Long distances should be tackled in good
health.
Driving under the influence
of drugs and/or some
medicines is highly dangerous for
oneself and for others.

USEFUL ACCESSORIES
Independently of current regulations, we
suggest you keep the following on board
(fig. 2):
– first aid kit containing non-alcoholic dis-
infectant, sterile gauzes, gauze roll, plas-
ters, etc.;
– electric torch;
– rounded scissors;
– work gloves.

– Disconnect the battery negative termi-
nal (–) from the battery and check the bat-
tery charge. This check should be repeated
once a month during stowage. Charge the
battery if the loadless voltage is below
12.5V.
– Do not empty the engine cooling sys-
tem.
– Cover the vehicle with a fabric or per-
forated plastic cover. Do not use compact
plastic covers which prevent the humidity on
the surface of the vehicle from evaporating.
USING AGAIN
Before using the car again after a pro-
longed period of inactivity, the following op-
erations are recommended:
– Do not dust the outside of the car.
– Check for leaks of fluids (oil, brake and
clutch fluid, engine coolant fluid, etc.).
– Change the engine oil and filter.
– Check the level of brake and clutch flu-
id engine coolant fluid.– Check the air cleaner and change it if
necessary.
– Check the tyre pressure and the tyres
for signs of damage, cuts or cracks. In this
case they need to be changed.
– Check the conditions of the engine belts.
– Re-connect the battery negative termi-
nal (–) after checking the battery charge.
– With the gears in neutral, start the en-
gine and let it idle a few minutes, pressing
the clutch pedal repeatedly.
This operation must be car-
ried out in the open.
Exhaust gas contains carbon
monoxide which highly toxic and
lethal.

IMPORTANT
Engine oil
Should prevailing use of the car be under
one of the following specially heavy condi-
tions:
– trailer or caravan towing
– dusty roads
– frequently idling engines or long distance
low speed driving or in case of a long term
inactivity
– short distances (less than 7-8 km) re-
peated and with external temperatures be-
low zero replace engine oil more frequent-
ly than required on Service Schedule.
IMPORTANT
Air cleaner
Using the car on dusty roads change the
air cleaner more frequently than specified in
the Scheduled Maintenance Programme.
For any doubts concerning the intervals be-
tween engine oil and air cleaner replacement
in relation to how the vehicle is used, con-
tact Alfa Romeo Authorised Services.IMPORTANT
Battery
It is advisable to check the battery charge,
preferably at the onset of winter, to prevent
the possibility of the electrolyte freezing.
This check should be carried out more fre-
quently if the car is used mainly for short
trips, or if it is fitted with accessories that
permanently absorb electricity even with the
ignition key removed, especially in the case
of after market accessories.
If the vehicle is used in hot climates or par-
ticularly harsh conditions it is wise to check
the level of the battery fluid (electrolyte)
more frequently than specified in the Sched-
uled Maintenance Programme.Vehicle maintenance should
be entrusted to Alfa Romeo
Authorised Services. For
routine and minor maintenance op-
erations you wish to carry out your-
self, always make sure you have the
proper equipment, genuine Alfa
Romeo spares and the necessary flu-
ids;do not however carry out these
operations if you have no experi-
ence.IMPORTANT
Pollen filter
If the vehicle is used frequently in dusty or
heavily polluted environments it is advisable
to replace the filtering element more fre-
quently; in particular it should be replaced
if a reduction of the amount of air admitted
to the passenger compartment is noted.
