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.

IMPORTANT
Engine oil
Should prevailing use of the car be under
one of the following specially heavy con-
ditions:
– trailer or caravan towing
– dusty roads
– short distances (less than 7-8 km)
repeated and with external temperatures
below zero
– frequently idling engines or long dis-
tance low speed driving or in case of a
long term inactivity
replace engine oil more frequently than
required on Service Schedule.IMPORTANT
Diesel filter
The different grades of purity in diesel
fuel normally available might make it nec-
essary to replace the filter more frequent-
ly than indicated in the Service Schedule.
If the engine misfires it shows the filter
needs changing.IMPORTANT
Air cleaner
Using the car on dusty roads change the
air cleaner more frequently than specified
in the Schedule Maintenance Programme.
For any doubts concerning the intervals
between the engine oil and air cleaner
replacement in relation to how the vehicle
is used, contact Alfa Romeo Authorised
Services.

DIESEL FUEL FILTER
(JTD16Vversions)
DRAINING CONDENSATION
WATER
The presence of water in
the supply circuit may
cause serious damage to
the entire injection system and
cause irregular running of the
engine. If the
cwarning light
turns on together with the mes-
sage on the reconfigurable multi-
function display, contact Alfa
Romeo Authorised Services as
soon as possible to have the sys-
tem relieved.
AIR CLEANER
The air cleaner is connected to the tem-
perature and air flow sensors which send
to the control unit the electric signals
needed for correct operation of the injec-
tion and ignition system.
It must therefore always be in perfect
conditions, to ensure correct operation of
the engine, low consumption and exhaust
emission levels.
If the operations con-
cerning cleaner replace-
ment described below are
not carried out correctly and with
the due precautions, they may
compromise the travelling safety
of the vehicle. You are recom-
mended to have this operation
carried out by Alfa Romeo
Authorised Services.
If the car is habitually
used in dusty areas, the
cleaner should be replaced
at shorter intervals than those
specified in the Programmed
Maintenance Schedule.
Any attempt to clean the
cleaner may damage it,
leading to serious engine
damage.

VEHICLE MAINTENANCE

Alloy rim painting
involving temperatures
exceeding 150 °C should
be avoided since wheel mechani-
cal characteristics could be
impaired.Do not cross switch the
tyres, moving them from
the right of the car to the
left and vice versa.Excessive low pressure
causes overheating of the
tyre with the possibility
of serious damage to it.Remember that vehicle
road holding also depends
on correct tyre inflation
pressure.
RUBBER HOSES
As far as the brake system and fuel sup-
ply rubber hoses are concerned, carefully
follow the Scheduled Maintenance
Programme. Indeed, ozone, high temper-
atures and the prolonged lack of fluid in
the system may cause hardening and
cracking of the hoses, with possible leaks.
Careful control is therefore necessary. IMPORTANTS
– Where possible, avoid sudden brak-
ing, tyre squealing starts, violent bumps
against kerbs, potholes or obstacles of var-
ious kinds. Prolonged driving on rough
roads may damage the tyres;
– Routinely check the tyres for cuts on
the sides, swellings or uneven tread wear.
If necessary contact Alfa Romeo
Authorised Services;
– Avoid overloading the vehicle when
travelling: this may cause serious damage
to the wheels and tyres;
– If a tyre is punctured, stop immedi-
ately and change it to avoid damage to
the tyre itself, the rim, suspensions and
steering system;
– Tyres age even if they are not used
much. Cracks in the tread rubber are a
sign of aging. In any case, if the tyres
have been on the vehicle for over 6 years,
they should be checked by specialised per-
sonnel, to see if they can still be used.
Also remember to check the compact
spare wheel;
– In case of replacement, always fit new
tyres, avoiding those of dubious origin;

Engine compartment
At the end of the winter the engine com-
partment should be carefully washed,
without directing the jet against electronic
control units. Contact a specialised work-
shop to have this done.
Detergents cause water
pollution. Therefore the en-
gine compartment should
be washed in areas equipped for
collecting and purifying the liquid
used in the washing process.
IMPORTANTThe vehicle should be
washed with the engine cold and the igni-
tion key at STOP. After washing make sure
that the various protections (e.g. rubber
caps and various covers) have not been
damaged or removed. Windows
Use specific products to clean the win-
dows. Use clean cloths to avoid scratching
or altering the transparency of the glass.
IMPORTANTThe inside of the
rearscreen should be wiped gently with a
cloth in the direction of the filaments to
avoid damaging the heating device.
Front headlights
IMPORTANTDo not use aromatic sub-
stances (e.g. petroleum) or ketones (e.g.
acetone) to clean the front headlight plas-
tic transparents.
Never use inflammable
products like fuel oil ether
or rectified petrol for
cleaning inside the car. The elec-
trostatic charges generated when
rubbing to clean may cause fire.
INTERIOR FITTINGS
Periodically check that water is not
trapped under the mats (due to water drip-
ping off shoes, umbrellas, etc.) which
could cause oxidisation on the sheet metal.
CLEANING SEATS AND FABRIC
AND VELVET PARTS
– Use a soft brush or a vacuum cleaner
to remove dust. Velvet is cleaned better if
the brush is moistened.
– Rub the seat with a sponge moistened
with a solution of water and neutral deter-
gent.
