SEAT BELTS
USING THE SEAT BELTS
The belt should be worn keeping the
chest straight and rested against the seat
back.
To fasten the seat belts: hold the
tongue (A-fig. 35) and insert it into the
buckle (B), until hearing the locking click.
At removal, if it jams, let it rewind for a
short stretch, then pull it out again without
jerking.To unfasten the seat belts:press
button (C-fig. 35). Guide the seat belt
with your hand while it is rewinding, to
prevent it from twisting. Through the reel,
the belt automatically adapts to the body
of the passenger wearing it, allowing free-
dom 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
webbing coming out when it is jerked or if
the car brakes sharply, in a collision or
when cornering at high speed.

IMPORTANTAfter control unit power
disconnection (battery replacement or dis-
connection and replacement of power win-
dow control unit protection fuses), the pow-
er window automatism shall be restored.
Proceed as follows with doors closed:
1.open the driver's window completely
keepingthe button pressedfor at least
3 seconds after window opening (window
lower stop);
2.close the driver's window completely
keepingthe button pressedfor at least
3 seconds after window closing (window up-
per stop);
3.repeat the same procedure (point 1 and
2) also for the front passenger's window;
4.check for proper initialisation by oper-
ating the windows automatically.

VDC SYSTEM
(Vehicle Dynamics Control)
(upon request for
versions/markets where
provided)
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 wheels;
– 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- 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 always be
adapted to the conditions of the
road surface, visibility and traffic.
The responsibility for road safety
is always and in any case the dri-
ver’s.
The VDC system helps the driver to keep
the car under control in the event of a loss
of tyre grip.
The forces induced by the VDC system to
control the loss of vehicle stability always
depend on the grip between the tyre and
the road surface.

ADDITIONAL
OPERATIONS
Every 1000 kmor before long jour-
neys, check and if necessary top up:
– engine coolant fluid level
– brake/hydraulic clutch control fluid
level
– power steering fluid level
– windscreen and headlamp washer
fluid level
– tyre pressure and conditions.
Every 3000 kmcheck and if necessary
top up the engine oil level.
The use of FL Seleniaproducts is rec-
ommended which have been designed
and made expressly for Alfa Romeo cars
(see “Refuelling” in the “Technical
Specifications” chapter).
ANNUAL INSPECTION
PROGRAMME
For cars with an annual mileage
of below 20,000 km (for exam-
ple about 10,000 km) the follow-
ing yearly inspection programme
is advised:
– Check tyre conditions/wear and if
necessary adjust the pressure (including
spare wheel)
– Check operation of lighting system
(headlights, direction indicators, hazard
warning lights, boot, passenger compart-
ment, glovebox lights, warning lights,
etc.)
– Check operation of windscreen wiper
system, spray jet adjustment
– Check position/wear of windscreen
– Check front disk brake pad conditions
and wear– Sight check for conditions of: engine,
gearbox, transmission, pipes (exhaust -
fuel supply - brakes), rubber parts (boots
- sleeves - bushes etc..), brake and fuel
supply system hoses
– Check for bonnet and boot lock clean-
ness, lever cleanness and lubrication
– Check battery charge
– Sight check for conditions of various
drive belts
– Check and if necessary top up fluid
levels (engine coolant, brakes, wind-
screen washer, battery etc. )
– Change engine oil and engine oil filter
– Change pollen filter.
