The rear seat is fitted with inertial seat belts
with three anchor points with reel for the
side seats and for the centre seat (fig. 36).
Through the reel, the belt automatically
adapts to the body of the passenger wear-
ing it, allowing freedom of movement.
When the car is parked on a steep slope
the reel mechanism may block; this is nor-
mal. The reel mechanism prevents the web-
bing coming out when it is jerked or if the
car brakes sharply, in a collision or when cor-
nering at high speed.To unfasten the seat belts, press button
(C). Guide the seat belt with your hand while
it is rewinding, to prevent it from twisting.

When the seat back is cou-
pled properly, the “red
band” (B) next to the seat back
levers (A) disappears. The “red
band” actually indicates improper
seat back coupling (fig. 36a). When
resetting it in proper position,
make sure to hear the locking click.
WARNING
After tilting, when reset-
ting the rear seat in
straight position, take care to repo-
sition the seat belt properly to
have it ready for use.
WARNING
Make sure the seat back is
correctly hooked on both
sides (not visible “red bands” (B))
to prevent seat back being thrown
forwards and injuring passengers
should you brake sharply.

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.
WARNING

CORRECT USE OF THE CAR
179
– Do not drive for long periods without a
break. During breaks get out of the vehicle
and move around a bit to shake off the
drowsiness.
– Make sure the air in the passenger com-
partment is changed constantly.
– Never coast the vehicle downhill with
the engine switched off: this eliminates the
engine braking and power steering effect
thus requiring a greater effort on the pedal
and steering wheel.
NIGHT DRIVING
Here are some suggestions for night dri-
ving.
– Drive with particular care: night driving
involves a greater degree of concentration.
– Reduce speed, especially on unlit roads.
– At the first signs of drowsiness stop the
car: continuing the journey is dangerous for
yourself and others. Continue driving only
after sufficient rest.
– Maintain a greater distance from the ve-
hicle in front than in the day: it is more dif-
ficult to judge the speed of a vehicle when
only the lights can be seen.
– Ensure that the headlights are correctly
aimed: if they are too low, visibility is re-
duced and eyesight is tired. If they are too
high they may cause disturbance to other
road users.
– Use the main beams only outside built-
up areas and only when you are certain that
other drivers are not disturbed by their use.
– When meeting oncoming vehicles,
switch off the main beams and drive with
the dipped-beam headlights on.
– Keep the headlights and light units
clean.
– Outside built-up areas take care of ani-
mal crossings.Always fasten the front and
rear seat belts including
those of any children’s seat. Trav-
elling without seat belts increases
the risks of serious injury or even
death in the event of an accident.
WARNING
Take car when fitting addi-
tional spoilers, alloy wheels
and wheel caps: they might reduce
ventilation of the brakes, thus their
efficiency, during abrupt and re-
peated braking, or long downhill
slopes.
WARNING
Never drive with objects
on the floor in front of the
driver’s seat: they might get stuck
under the pedals making it impos-
sible to accelerate or brake.
WARNING
Make sure any mats are
appropriate in size: even a
slight inconvenience to the braking
system may require a higher ped-
al stroke than normal.
WARNING
Water, ice and salt on the
roads may deposit on the
brake disks, reducing the effec-
tiveness of the brakes the first
time they are used.
WARNING

CORRECT USE OF THE CAR
180
DRIVING WITH RAIN
Rain and wet roads can be dangerous.
If the road is wet, the traction between
wheel and asphalt is greatly reduced, thus
increasing the stopping distance and de-
creasing road holding.
Here are a few suggestions in the case of
rain:
– Reduce speed and keep further back
from the vehicle in front.
– Heavy rain also reduces visibility. In
these cases, turn on the headlights even dur-
ing the day to make yourself more visible
to others.
– Do not drive over puddles at high speed
and hold the steering wheel firmly: you may
lose control of the car (aquaplaning).
– Position the ventilation controls for
demisting (as described in the chapter (“Get-
ting to know your car”), to prevent visibili-
ty from worsening.
– Routinely check the conditions of the
windscreen wiper blades.
DRIVING IN FOG
– If fog is very thick, avoid travelling
where possible. If travelling with mist,
ground fog or the possibility of fog banks:
– Drive at moderate speed.
– Also in the day turn on the dipped-beam
headlights, rear fog guards and front fog
lights. Do not use the main-beam headlights.
IMPORTANTIf visibility in some parts
improves, switch off the rear fog guards; the
intense light disturbs the occupants of ve-
hicles behind.
– Remember that fog also involves wet
asphalt, thus greater difficulty in all types of
manoeuvres and longer stopping distances.
– Keep well away from the vehicle in
front.
– Where possible avoid sudden changes
in speed.
– Possibly avoid overtaking other vehicles.
– If the vehicle is forced to stop (faults,
impossibility to continue due to poor visi-
bility, etc.), firstly try to pull off the road.
Then turn on the hazard warning lights and,
if possible the dipped-beam headlights.
Rhythmically sound the horn if you note an-
other car coming.
MOUNTAIN DRIVING
– When travelling down hill use the en-
gine braking by engaging lower gears to pre-
vent the brakes from overheating.
– Never coast down hill with the engine
off or in neutral and especially not with the
ignition key removed.
– Drive at a moderate speed and avoid
cutting corners.
– Remember that overtaking up hill is
slower and therefore requires a greater
length of clear road. If you are being over-
taken on a hill, move over to enable the oth-
er vehicle to pass in safety.

SPARK PLUGS
Clean, intact spark plugs are determinant
with regard to engine efficiency and for re-
ducing the emission of pollutants.Spark plugs should be re-
placed at the intervals
specified in the Scheduled
maintenance programme. Only use
spark plugs of the specified type:
if the thermal capacity is inade-
quate or if the envisaged life is not
guaranteed inconveniences may en-
sue.
BRAKES
Service brakes: – front
– rear
Parking brake
If examined by an expert eye, the ap-
pearance of a spark plug is a sound clue
for locating a fault, even if not involving the
ignition system. Therefore if you are expe-
riencing any engine problems, it is impor-
tant to have the spark plugs checked by Al-
fa Romeo Authorized Services.
