WATER IN DIESEL
FUEL FILTER
(diesel versions)
Message + symbol are displayed when
travelling to indicate that there is water in
the diesel fuel filter.
DIESEL PARTICULATE
FILTER CLOGGED
(diesel versions)
(upon request for
versions/markets
where applicable)
Message + symbol are displayed when the
diesel particulate filter is clogged and the dri-
ving conditions do not enable to activate au-
tomatically the reclaiming procedure.
To enable the cleaning procedure, keep the
car running until the message + symbol turn
off. Glow plug warming failure
Message + symbol are displayed when
there is a failure in the glow plug warming
system. Contact Alfa Romeo Authorized Ser-
vices as soon as possible to have the fault
eliminated.

The presence of water in
the fuel circuit may cause
serious damage to the en-
tire injection system and cause ir-
regular engine operation. If mes-
sage + symbol are displayed on the
reconfigurable multifunction display
contact Alfa Romeo Authorized
Services as soon as possible to
have the system relieved. If the
above indications come on immedi-
ately after refuelling, water has
probably been poured into the
tank: turn the engine off immedi-
ately and contact Alfa Romeo Au-
thorized Services.

DIESEL ENGINES
If the outside temperature is very low, the
diesel thickens due to the formation of paraf-
fins and could clog the diesel fuel filter.
In order to avoid these problems, different
types of diesel are distributed according to
the season: summer type, winter type arc-
tic type (mountains/cold areas).
If refuelling with diesel fuel not suitable for
the current temperature, mix diesel fuel with
TUTELA DIESEL ARTadditive in the pro-
portions stated on the can, putting first the
antifreeze in the tank and then the diesel
fuel.
TUTELA DIESEL ARTshall be added to
diesel fuel before the due to cold take place.
Adding it later will be worthless. If driving or
parking the vehicle for a long period in cold
areas/mountains, refuel with the diesel fu-
el available at local filling stations. In this
situation you are also recommended to have
in the tank an amount of fuel 50% higher
than usable capacity.
REFUELLING
PETROL ENGINES
Use only unleaded petrol.
To prevent accidentally filling with leaded
petrol, the diameter of the fuel tank filler
is of such a size as not to accept the noz-
zle of this type of petrol.
The unleaded petrol octane number
(R.O.N.) used shall not be less than 95.
IMPORTANTAn inefficient catalyst
leads to harmful emission at the exhaust,
thus environment pollution.
IMPORTANTUnder no circumstances
should conventional leaded petrol be used,
as this would irreparably damage the cata-
lyst.Cars with diesel engines
must only be filled with
diesel fuel for motor vehi-
cles, in compliance with European
Specification EN590. The use of
other products or mixtures may ir-
reparably damage the engine with
invalidation of the warranty due to
the damage caused. In the event of
accidentally filling with another
type of fuel, do not start the en-
gine and empty the tank. If the en-
gine has been run even for only a
very short time, in addition to the
tank, it is also necessary to drain
out the whole fuel circuit.

The devices used to reduce diesel fuel en-
gine emissions are:
– oxidising catalyst;
– exhaust gas recirculation system (E. G. R.);
– diesel particulate filter (DPF). DPF (Diesel Particulate Filter)
(for versions/ markets where
applicable)
The Diesel Particulate Filter is a mechani-
cal filter, integral with the exhaust system,
that physically traps particulates present in
the exhaust gases of Diesel engines.
The diesel particular filter has been adopt-
ed to eliminate almost totally particulates in
compliance with current / future law regu-
lations.
During normal use of the car, the engine
control unit records a set of data (e.g.: trav-
el time, type of route, temperatures, etc.)
and it will then calculate how much partic-
ulates has been trapped by the filter.
Since this filter physically traps particulates,
it shall be cleaned (reclaimed) at regular in-
tervals by burning carbon particles.
ENVIRONMENTAL
PROTECTION
The devices used to reduce petrol engine
emissions are:
– trivalent catalytic converter (catalytic si-
lencer);
– Lambda sensors;
– anti-evaporation system.
If one or more spark plugs are discon-
nected, do not run the engine, even for a
test.During normal service the
catalyst and the diesel par-
ticulate filter (DPF) reach
high temperatures. Do not there-
fore park the car over inflammable
materials (grass, dry leaves, pine
needles, etc.): fire hazard.

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-
er fluid level
– tyre pressure and conditions.

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 Specifica-
tions” chapter).
ANNUAL INSPECTION
PROGRAMME
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.

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.
