FUEL CAP
The fuel cap (C-fig. 164) is electrically
controlled. To open it, press button (D-
fig. 165); the flap can be opened only
when the engine is off.
The fuel cap (A-fig. 164), accessible af-
ter opening the lid (C), is fitted with a catch
to prevent losing it (B) which fastens it to the
lid.
When refuelling, hook the cap to the de-
vice on the inner flap, as illustrated.
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.
IMPORTANT An inefficient catalyst
leads to harmful emission at the exhaust,
thus environment pollution.
IMPORTANTNever put leaded petrol,
even in small quantity, in the tank, even if
it is an emergency. This would irreversibly
damage the exhaust gas catalyst.
JTD ENGINES
At low temperatures the degree of fluidi-
ty of fuel oil may become insufficient due to
the formation of paraffins leading to mal-
functioning of the fuel system.
Therefore, to avoid inconveniences, sum-
mer and winter fuel oils are normally dis-
tributed depending on the season.
In the event the car is filled with fuel oil
unsuitable for the using temperature, mix
it with DIESEL MIX additive in the propor-
tions stated on the can, firstly putting the
antifreeze in the tank and then the fuel oil.
The vehicle must only be
filled with fuel oil for mo-
tor vehicles, in compliance
with European Specification
EN590. The use of other products
or mixtures may irreparably dam-
age the engine with invalidation of
the warranty due to the damage
caused. In the event of accidental-
ly filling with another type of fuel,
do not start the engine and empty
the tank. If the engine has been run
even for only a very short time, in
addition to the tank, it is also nec-
essary to empty the whole supply
circuit.

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.

CHECKING LEVELS
Never smoke while

sent, with the risk of fire.
When topping up take
care not to confuse the
various types of fluids:
they are incompatible with one
another and could seriously dam-
age the vehicle.fig. 1 - 1.8 T. SPARK version

ENGINE OIL (fig. 4-4a-5-6)
The engine oil should be checked with
the vehicle on a level surface a few min-
utes (about 5) after the engine has been
switched off.
Remove the dipstick (A), clean it, put it
back in completely, remove it and check
that the level is within the MINand
MAXmarks on the dipstick. The interval
between the MINandMAXmarks cor-
respond to about one litre of oil.When the engine is hot,
take care when working
inside the engine com-
partment to avoid burns.
Remember that when the engine
is hot, the fan may cut in: danger
of injury.
Do not add oil with spec-
ifications (classification,
viscosity) other than
those of the oil already in the
engine.

If the oil level is near or even below the
MINmark, add oil through the filter neck
(B), until reaching the MAXmark.
IMPORTANTIf a routine check
reveals that the level is above the MAX
mark, contact Alfa Romeo Authorised
Services to have the correct level restored.
IMPORTANTAfter topping up the oil,
before checking the level again, run the
engine a few seconds and wait for a few
minutes ater stopping it.

Used engine oil and filter
contain harmful sub-
stances for the environ-
ment. Contact Alfa Romeo
Authorised Services to have the
oil and the filter changed, as they
are equipped to dispose of the
waste oil and filters respecting
nature and the law.
SELESPEED TRANSMISSION
OIL
(fig. 7)
The Selespeed transmission oil should be
checked with the vehicle on a level sur-
face and with the engine stopped and
cold.
To check the level, proceed as follows:
– turn the ignition key to MAR;
– disconnect the breather tube and
remove the cap (A) checking that the
level corresponds with the MAXmark on
the dipstick integrated with the cap;
– if the oil is below the MAXmark, top
up to reach the correct level;Do not add oil with spec-
ifications other than that
already in the gearbox.
fig. 7
A0A0197b
Used gearbox oil con-
tains dangerous sub-
stances for the environ-
ment. For changing the oil we
advise contacting Alfa Romeo
Authorised Services who are
equipped for disposing of used oil
respecting nature and the law.
Be very careful working
inside the engine com-
partment if the engine is
hot: danger of burns. Remember
that the fan may cut in if the
engine is very hot: danger of
injury.
Engine oil consumption
Max engine oil consumption is usually
400 grams every 1000 km.
During the initial period of use the
engine settles, therefore engine oil con-
sumption may be considered stabilised
only after the first 5000 ÷ 6000 km.
IMPORTANTEngine oil consumption
depends on the way of driving and the
conditions of use of the vehicle.– after refitting the cap, insert the
breather tube firmly on the housing on the
cap and turn the ignition key to STOP.
