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.
The devices used to reduce diesel fuel en-
gine emissions are:
– oxidising catalyst;
– exhaust gas re-circulation system
(E. G. R.). Do not go near the fuel
filler with naked flames or
lit cigarettes: danger of
fire. Avoid going too near the fuel
filler with your face, to avoid in-
haling harmful vapours.
In the case of need, only
replace the fuel cap with
another genuine one, or the
efficiency of the fuel vapour re-
covery system could be adversely
affected.
Should it be not possible to open the fuel
flap electrically, use the special cable in the
boot (A-fig. 166) to open it manually.
Due to the high tempera-
tures reached during oper-
ation of the catalytic si-
lencer the vehicle should not be
parked over inflammable materials
(grass, dry leaves, pine needles,
etc.).

IMPORTANTThe sealing of the tank
may cause light pressurising. A little breath-
ing off, while slackening the cap is ab-
solutely normal.
After refuelling, turn the cap clockwise and
close the flap.
IMPORTANTFor your safety, before
starting the engine, also make sure that the
fuel nozzle is correctly inserted in the fuel
distributor.

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.
