PROTECTIVE SHIELD UNDER
ENGINE
The car is fitted with a protective shield
under the engine.
IMPORTANTWhen changing the en-
gine oil and filter, checking and changing
the gearbox and differential oil, this pro-
tection should be removed. This operation
should be carried out by Alfa Romeo Au-
thorized Services.
CHECKING ENGINE OIL LEVEL
Fig. 3:3.2 V6 24V version
Fig. 4:JTD 20V Multijet version
The engine oil level should be checked
when the vehicle is standing on a level
surface a few minutes (about 5) after the
engine has been switched off.
Remove the dipstick (A), clean it, then
re-insert it completely, remove it once again
and check that the level is between the
MIN and MAX marks on the dipstick.The interval between the MIN and MAX
marks corresponds to approximately 1
litre of oil.
Max. engine oil consumption is usually
400 grams every 1000 km.
When the car is new, the engine needs
to run in, therefore the engine oil con-
sumption can only be considered sta-
bilised after the first 5000-6000 km.

Any attempt to clean
the air cleaner may
cause serious engine
damage.
If they are not carried
out correctly and with
the due precautions, the
operations involving cleaner re-
placement described herein may
compromise the safety of the
car. This operation should be car-
ried out by Alfa Romeo Autho-
rized Services.
AIR CLEANER
The air cleaner is connected to the tem-
perature and air flow sensors which send
the electrical signals needed for correct
operation of the injection and ignition sys-
tem to the control unit.
It must therefore always be in perfect
conditions to ensure correct operation of
the engine, low consumption and exhaust
emission levels.When the car is habitu-
ally driven in dusty ar-
eas, the cleaner should
be changed at shorter intervals
than those given in the Pro-
grammed Maintenance Schedule.
IMPORTANT When topping up use
the special detergents available in the
shops ensuring that they contain antis-
cale and antifreeze properties.
If in doubt contact Alfa Romeo Autho-
rized Services who will be able to recom-
mend the most suitable products.
Do not travel with the
windscreen washer
reservoir empty: the action of the
windscreen washer is fundamental
for improving vision.
