Performance of the
VDC system, in terms
of active safety should not in-
duce the driver to take point-
less and unnecessary risks.
The style of driving must in
any case always be adapted to
the conditions of the road sur-
face, visibility an traffic. Road
safety is always the driver’s
responsibility.
WARNING
During the use of the
space-saver spare
wheel (where provided), the
VDC system carries on work-
ing. However, you must re-
mind that the space-saver
spare wheel has dimensions
smaller than the standard tyre
and therefore its grip is re-
duced as to the other car tyres.
WARNING
For correct operation of
the VDC system, the
tyres must absolutely be of
the same brand and type on all
wheels, in perfect conditions
and, above all, of type, brand
and size specified.
WARNING
HILL HOLDER SYSTEM
(where provided)
This system is an integral part of the VDC
system and it is provided to facilitate
starting on slopes:
❒uphill: car at a standstill on a road
with a gradient higher than 6%, en-
gine running, clutch and brake ped-
al depressed, gearbox to neutral or
engaged gear other than reverse;
❒downhill: car at a standstill on a road
with a gradient higher than 6%, en-
gine running, clutch and brake ped-
al depressed and reverse gear en-
gaged.
At pickup the VDC system control unit
will keep brake force on wheels until
reaching the torque suitable for starting,
or in any case for about 1 second in or-
der to pass easily from the brake pedal
to the accelerator pedal.

CORRECT USE
OF THE CARTo engage reverse Rfrom neutral, raise
ringA-fig. 3under the knob and at
the same time move the gearshift lever
leftwards and then forward. After en-
gaging reverse release the ring. To shift
from reverse to another gear it is not
necessary to raise the ring.
IMPORTANT The car can only be put
into reverse gear when it has stopped
moving completely. With the engine run-
ning, before engaging the reverse, wait
at least 3 seconds with the clutch ped-
al fully down to prevent damage and
grating of the gears.
A0E0151mfig. 3
To change gears prop-
erly you must push the
clutch pedal fully down. It is
therefore essential that there
is nothing under the pedals:
make sure mats are lying flat
and do not get in the way of
the pedals.
WARNING
Do not drive with your
hand resting on the gear
lever as the force ex-
erted, even if slight, could lead
over time to premature wear on
the gearbox internal compo-
nents.
USING THE
GEARBOX
The car is fitted with 6-gear manual
gearbox. Gear positions are shown on
the gearshift lever knob.
Always press down the clutch pedal
when shifting gears. To engage the 6
th
gear, move the gearshift lever pressing
slightly rightwards to prevent engaging
the 4
thgear accidentally.

USE OF THE CAR
UNDER HEAVY
CONDITIONS
Should prevailing use of the car be un-
der one of the following specially heavy
conditions:
❒ trailer or caravan towing;
❒ dusty roads;
❒ short distances (less than 7-8 km)
and repeated with external temper-
atures below zero;
❒ frequently idling engines or long dis-
tance low speed driving (e.g.: door-
to-door deliveries) or in case of a long
term inactivity;
❒ urban routes;
carry out checks more frequently than
required on Service Schedule:
❒ check front disk brake pad conditions
and wear;
❒ check cleanness of bonnet and boot
locks and lever cleanness and lubri-
cation;
❒ sight inspect the conditions of: en-
gine, gearbox, transmission, pipes
and hoses (exhaust - fuel - brakes),
rubber parts (boots, sleeves, bushes,
etc.);
❒ check battery charge and fluid level
(electrolyte);
❒ visual check on various drive belt con-
ditions;
❒ change engine oil and oil filter, if re-
quired;
❒ check and replace pollen filter, if re-
quired;
❒ check and replace air cleaner, if re-
quired.
PERIODICAL CHECKS
Every 1,000 km or before long jour-
neys, check and top up if required:
❒engine coolant fluid level;
❒brake fluid level;
❒windscreen washer fluid level;
❒ tyre pressure and conditions.
❒ check light system operation (head-
lights, direction indicators, hazard
lights, etc.);
❒ check windscreen wiper/washer op-
eration and windscreen/rear window
blade position/wear;
Every 3,000 km check and top up if re-
quired: engine oil level.
You are recommended to use FL Se-
leniaproducts, designed and produced
specifically for Alfa Romeo cars (see
table “Capacities” in section “Techni-
cal specifications”).

IMPORTANTIn the event of difficult disengagement, due to significant difference of grip between front and rear axle, do
not insist with heavy accelerations: it is actually more effective an attempt of disengagement at medium slow engine rpm,
with pauses of a few seconds if several attempts are necessary.
