ADDITIONAL
OPERATIONS
Every 1000 kmor before long journeys,
check and if necessary top up:
– engine coolant fluid level
– brake/hydraulic clutch control fluid level
– power steering fluid level
– windscreen washer and headlamp wash-

The use of FL Seleniaproducts is rec-
ommended which have been designed and
made expressly for Alfa Romeo cars (see
“Refuelling” in the “Technical Specifica-

For cars with an annual mileage
of below 20,000 km (for example
about 10,000 km) the following
yearly inspection programme is ad-
vised:
– Check tyre conditions/wear and if nec-
essary 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 windscreen blade position/wear
– Check front disk brake pad conditions
and wear
– Check cleanness of bonnet and boot
locks, and lever cleanness and lubrication.– Sight check for conditions of: engine,
gearbox, transmission, pipes (exhaust - fu-
el supply - brakes), rubber parts (boots -
sleeves - bushes etc..), brake and fuel sup-
ply system hoses
– Check battery charge
– Sight check for conditions of various dri-
ve belts
– Check and if necessary top up fluid lev-
els (engine coolant, brakes, windscreen
washer, battery etc. )
– Change engine oil and oil filter
– Change pollen filter.

IMPORTANT
Engine oil
Should prevailing use of the car be under
one of the following specially heavy condi-
tions:
– trailer or caravan towing
– dusty roads
– short distances (less than 7-8 km) re-
peated and with external temperatures be-
low zero
– frequently idling engines or long distance
low speed driving or in case of a long term
inactivity
replace engine oil more frequently than re-
quired on the Scheduled Maintenance Pro-
gramme.IMPORTANT
Diesel filter
The variety of the degree of purity of the
fuel oil in commerce may make it necessary
to change the fuel oil filter more frequently
than stated in the Scheduled Maintenance
Programme. If the engine is “sobbing” it
is a sign that 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 be-
tween the engine oil and air cleaner re-
placement in relation to how the car is used,
contact Alfa Romeo Authorised Services.

DIESEL FUEL FILTER
(diesel versions)
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 en-
gine. If the warning message +
symbol are shown on the recon-
figurable multifunction display con-
tact Alfa Romeo Authorized Ser-
vices as soon as possible to have
the system relieved. If warning in-
dications turn on after refuelling,
water has probably been poured
into the tank: turn the engine off
immediately and contact Alfa
Romeo Authorized Services.
AIR CLEANER
The air cleaner is connected to the tem-
perature and air flow sensors which send
to the control unit the electric signals need-
ed for correct operation of the injection and
ignition system.
It must therefore always be in perfect con-
ditions, to ensure correct operation of the
engine, low consumption and exhaust emis-
sion levels.
If the operations concern-
ing cleaner replacement de-
scribed below are not car-
ried out correctly and with the due
precautions, they may compromise
the travelling safety of the car. You
are recommended to have this op-
eration 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 Main-
tenance Schedule.
Any attempt to clean the
cleaner may damage it,
leading to serious engine
damage.

CAR MAINTENANCE

Alloy rim painting involv-
ing temperatures exceed-
ing 150 °C should be
avoided since wheel mechanical
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 car road
holding also depends on
correct tyre inflation pres-
sure.
RUBBER HOSES
As far as the brake system and fuel sup-
ply rubber hoses are concerned, carefully fol-
low the Scheduled Maintenance Pro-
gramme. Indeed, ozone, high temperatures
and the prolonged lack of fluid in the sys-
tem may cause hardening and cracking of
the hoses, with possible leaks. Careful con-
trol is therefore necessary.
IMPORTANT NOTES
– Where possible, avoid sudden braking,
tyre squealing starts, violent bumps against
kerbs, potholes or obstacles of various kinds.
Prolonged driving on rough roads may dam-
age the tyres;
– Routinely check the tyres for cuts on the
sides, swellings or uneven tread wear. If nec-
essary contact Alfa Romeo Authorised Ser-
vices;
– Avoid overloading the car when travel-
ling: this may cause serious damage to the
wheels and tyres;
– If a tyre is punctured, stop immediate-
ly and change it to avoid damage to the tyre
itself, the rim, suspensions and steering sys-
tem;
– 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 car for over 6 years, they should be
checked by specialised personnel, 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, with-
out directing the jet against electronic con-
trol units. Contact a specialised workshop 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 car should be washed
with the engine cold and the ignition 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 windows.
Use clean cloths to avoid scratching or al-
tering 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 clean-
ing inside the car. The electrostat-
ic charges generated when rubbing
to clean may cause fire.
INTERIOR FITTINGS
Periodically check that water is not trapped
under the mats (due to water dripping 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.
