HEADLIGHT WASHERS(optional for versions/markets
where applicable)
Regularly check that the spray jets are in-
tact and clean fig. 28.
If it is necessary to direct the jet, contact
an Alfa Romeo Authorized Service.
BODYWORKPROTECTION FROM
ATMOSPHERIC AGENTSThe main causes of corrosion are:
– atmospheric pollution
– salty air and humidity (coastal areas, or
hot humid climates)
– seasonal environment conditions.
Not to be underestimated is also the abra-
sive action of wind-borne atmospheric dust
and sand and mud and gravel raised by oth-
er vehicles.
On your Alfa 156, Alfa Romeo has
implemented the best manufacturing tech-
nologies to effectively protect the bodywork
against corrosion.
These include:
– Painting products and systems which
give the car particular resistance to corrosion
and abrasion.
– Use of galvanised (or pretreated) steel
sheets, with high resistance to corrosion.
– Spraying the underbody, engine com-
partment, wheel arches and other parts with
highly protective wax products.
SPRAY JETS Make sure that the windscreen and head-
light (where applicable) washer jets deliv-
er a jet of fluid which is adequate and cor-
rectly directed.
If the spray devices are not working check
that the supply circuit is not blocked. If nec-
essary unblock the nozzles using a needle.

CAR MAINTENANCE
276
Detergents cause water
pollution. Therefore the en-
gine compartment should
be washed in areas equipped for
collecting and purifying the liquid
used in the washing process.
WARNINGThe vehicle should washed
with the engine cold and the ignition key at
STOP. After washing make sure that the
various protections (e.g. rubber caps and
various covers) have not been damaged or
removed. Do not wash the car after it has been left
in the sun or with the bonnet hot: this may
alter the shine of the paintwork.
Exterior plastic parts must be cleaned in
the same way as the rest of the vehicle.
Where possible, do not park under trees;
the resinous substance many species release
give the paint a dull appearance and in-
crease the possibility of triggering rust
processes.
WARNINGBird droppings must be
washed off immediately and thoroughly as
the acid they contain is particularly ag-
gressive.Windows
Use specific products to clean the windows.
Use clean cloths to avoid scratching or al-
tering the transparency of the glass.
WARNINGThe inside of the rearscreen
should be wiped gently with a cloth in the
direction of the filaments to avoid damag-
ing the heating device. Engine compartment
At the end of the winter the engine com-
partment should be carefully washed, with-
out directing the jet against electronic con-
trol units. Contact a specialised workshop to
have this done.

CURRENT SOCKET (optional for versions/markets
where applicable) (fig. 20)
This is on the left-hand side of the boot.
To use the socket, open the lid (A). The
socket is supplied with the ignition switch at
MARand can only be used with accessories
that absorb a maximum of 15A (power
180W).
OBJECTS RETAINER NET(optional for versions/markets
where applicable)
The net can be hooked in different posi-
tions (fig. 24-25-26-27) using hous-
ings (Aand B-fig. 21) provided in the
front part of the boot and housings (Cand
D-fig. 22) in the rear part. Do not connect acces-
sories with higher absorp-
tion to the socket. Pro-
longed current absorption might
drain the battery preventing the
engine from being started.

SPARK PLUGClean, intact spark plugs are determinant
with regard to engine efficiency and for re-
ducing the emission of pollutants.Spark plugs should be re-
placed at the intervals
specified in the Scheduled
Maintenance Programme. Only use
spark plugs of the specified type: if
the thermal capacity is inadequate
or if the envisaged life is not guar-
anteed inconveniences may ensue.BRAKESService brakes:
– front
– rearParking brake
If examined by an expert eye, the ap-
pearance of a spark plug is a sound clue
for locating a fault, even if not involving the
ignition system. Therefore if you are expe-
riencing any engine problems, it is impor-
tant to have the spark plugs checked by Al-
fa Romeo Authorized Services.
