VDC SYSTEM
(Vehicle Dynamics Control)
This is an electronic system that controls vehicle stability in the
event of tyre grip loss, helping maintain directional control. The sys-
tem is capable of recognising potentially dangerous situations in
terms of the stability and intervenes automatically on the brakes
in a differentiated manner for the four wheels in order to provide
a stabilizing torque.
The VDC, in turn, includes the following systems:
❍Hill Holder
❍ASR
❍Brake Assist
❍MSR
❍CBC
❍“ELECTRONIC Q2” (“E-Q2”)
❍DST
❍RAB
SYSTEM INTERVENTION
This is signalled by warning lightáblinking on the instrument
panel to inform the driver that stability and grip conditions are
critical.
SYSTEM ACTIVATION
The VDC system switches on automatically each time the engine
is started and cannot be switched off.
HILL HOLDER SYSTEM
This system is an integral part of the VDC system and it is provided
to facilitate starting on slopes.
It is activated automatically in the following instances:
❍uphill: car standing on a road with a gradient of more than 5%,
engine on, brake pedals pressed and gearbox in neutral or gear
(other than reverse) engaged;
❍downhill: car at a standstill on a road with a gradient higher
than 5%, engine running, brake pedal pressed and reverse gear
engaged.
When setting off the VDC system control unit maintains the brak-
ing pressure at the wheels until the engine torque required for de-
parture is reached or for approximately 2 seconds, allowing your
right foot to be moved easily from the brake pedal to the acceler-
ator.
If the car does not start off after this time, the system will deacti-
vate automatically by gradually releasing the brake force. A noise
may be heard: this means that the car is about to start moving.
IMPORTANT the Hill Holder system should not be used as a hand-
brake. Do not leave the vehicle without having engaged the hand-
brake, switched off the engine and engaged a gear.

“ELECTRONIC Q2” SYSTEM (“E-Q2”)
The “Electronic Q2” system uses the braking system to create an
effect similar to a limited slip differential.
The front braking circuit, when accelerating around a corner, acts
on the inside wheel to increase the drive to the outside wheel (in-
creased load), dynamically and continuously distributing the torque
between the front drive wheels according to driving and road con-
ditions.
The system, combined with Mc Pherson front suspension, allows
particularly effective, sporty driving.
DST SYSTEM (Dynamic Steering Torque)
This function integrates Dual Pinion active steering into the opera-
tion of VDC. For particular manoeuvres, VDC controls the steering
to actuate a steering torque and assist the driver in the best pos-
sible way. The system operates the brakes and steering in a coor-
dinated manner to increase the suspension and safety level of the
car as a whole. The steering provides addition torque on the steer-
ing wheel.
RAB SYSTEM (Ready Alert Brake)
(“Dynamic” mode only)
By pre-approaching the brake pads (front and rear) after rapid ac-
celerator release, this function provides prompter braking and re-
duces stopping distance.
BRAKE ASSIST
(emergency braking assistance)
The system, which cannot be turned off, recognises emergency
braking (on the basis of the brake pedal operating speed) and
speeding up the response of the braking system. The Brake
Assist function is deactivated in the event of VDC system fault.
MSR SYSTEM
(Motor Schleppmoment Regelung)
This system is an integral part of the ABS, that intervenes, if there
is a sudden change to a lower gear, restoring torque to the engine,
thereby preventing excessive drive at the drive wheels which, es-
pecially in poor grip conditions, could lead to a loss in stability.
CBC SYSTEM (Cornering Braking Control)
This system improves the distribution of the braking pressure at the
four wheels (to fully exploit the grip available on the ground) when
braking round bends when the ABS intervenes. This improves stop-
ping distances and above all vehicle stability when cornering.

Contact Alfa Romeo Authorized Services should the
fuse blow again.
Never replace a blown fuse with metallic wires or
other material.
Never replace a fuse with another of higher am-
perage: FIRE RISK.
If a general protection fuse (MEGA-FUSE, MIDI-
FUSE, MAXI-FUSE) blows, contact Alfa Romeo
Authorized Services.
Remove the key from the ignition switch and switch
off all loads before replacing a fuse.
Contact Alfa Romeo Authorized Services if a safe-
ty system (air bags, brakes), engine system (en-
gine, gearbox) or steering system general pro-
tection fuse blows.

REGULAR CHECKS
Every 1,000 km or before long journeys, check and top up the fol-
lowing if necessary:
❍engine coolant level, brake fluid and windscreen washer fluid
❍tyre pressure and condition;
❍operation of lighting system (headlights, direction indicators,
hazard lights, etc.);
❍operation of the windscreen wiper/washer system, position
and wear of windscreen/rear window wiper blades;
Check and top up, if required, the engine oil level every 3,000 km.
We recommend the use of PETRONAS LUBRICANTS, designed and
produced specifically for Alfa Romeo cars (see “Capacities” table
in the “Technical Specifications” chapter).
DEMANDING USE OF THE CAR
If you use the car mainly under one of the following conditions:
❍trailer or caravan towing;
❍dusty roads;
❍short (less than 7-8 km) and repeated journeys in sub-zero
temperatures;
❍frequent engine idling, travelling long distances at low speeds
or long term inactivity;
❍in cities;
perform the following inspections more frequently than shown on
the Scheduled Servicing Plan:
❍check front disc brake pad condition and wear;
❍check cleanliness of bonnet and boot locks, as well as cleanli-
ness and lubrication of linkages;
❍visually inspect the conditions of: engine, gearbox, transmis-
sion, pipes and tubes (exhaust - fuel - brakes), rubber parts
(boots, sleeves, bushes, etc.);
❍check battery charge and liquid level (electrolyte);
❍visually inspect the condition of auxiliary drive belts;
❍check and if necessary change engine oil and oil filter;
❍check pollen filter and replace it, if required;
❍check air filter and replace, if required.
