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

c warning light turns

on (or, on some versions, symbol +
message are shown on the recon-
figurable multifunction display)
contact Alfa Romeo Authorised
Services as soon as possible to
have the system relieved. If the
same warning appears immediate-
ly after refuelling, some water
could have been introduced in the
reservoir: in this case turn off the
engine immediately and contact Al-
fa Romeo Authorised 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.
