2006 Alfa Romeo 156 service schedule

CAR MAINTENANCE
253
Car maintenance should be
entrusted to Alfa Romeo
Authorized Services. For
routine and minor maintenance op-
erations you wish to carry out
yourself, always make sure you
have the proper equipment, genuine
Alfa Romeo spare parts and the
necessary fluids; do not however
carry out these operations if you
have no experience.
WARNING
Pollen filter
If the car is used frequently in dusty or
heavily polluted environments it is advisable
to replace the filtering element more fre-
quently; in particular it should be replaced if
a reduction of the amount of air admitted to
the passenger compartment is noted. WARNING
Battery
You are recommended to have the battery
charge conditions checked, preferably at the
onset of winter, to avoid the possibility of
freezing the electrolyte.
This check should be carried out more fre-
quently if the car is used prevailingly for
short journeys, or if it is fitted with services
that absorb high amounts of current per-
manently with the ignition key off, especially
if installed in the after market.
In the case of use of the car in hot climates
or particularly harsh conditions, it is wise
to check the level of the battery fluid (elec-
trolyte) at more frequent intervals than stat-
ed in the Scheduled Maintenance Pro-
gramme.

DIESEL FILTERDRAINING CONDENSATION
WATER
Water in the supply circuit
can seriously damage the
whole injection system and
cause malfunctions to engine oper-
ation. Should the warning lamp
c
turn on, available for the provid-
ed versions/markets, contact as
soon as possible the Alfa Romeo
Authorised Service for drainage op-
erations.
When the car is habitual-
ly driven in dusty areas,
the cleaner should be
changed at shorter intervals than
those given in the Programmed
Maintenance Schedule.Any attempt to clean the
air cleaner may cause se-
rious engine damage.
AIR FILTERThe air cleaner is connected to the tem-
perature and air flow sensors which send the
electrical signals needed for correct opera-
tion of the injection and ignition system to
the control unit.
It must therefore always be in perfect con-
ditions to ensure correct operation of the en-
gine, low consumption and exhaust emis-
sion levels.
If they are not carried out
correctly and with the due
precautions, the operations
involving cleaner replacement de-
scribed herein may compromise the
safety of the car.
This operation should be carried
out by Alfa Romeo Authorized Ser-
vices.

BATTERYThe battery is of the “Limited Mainte-
nance” type and is fitted with an optical in-
dicator (A-fig. 23) for checking the elec-
trolyte level and charge.
Under normal conditions of use the elec-
trolyte does not need topping up with dis-
tilled water. To make sure that it is in effi-
cient conditions, at routine intervals check
the indicator on the battery cover which
should be dark in colour with a green cen-
tral area.
If the indicator is a bright light colour, or
dark without the green central area, contact
Alfa Romeo Authorized Services.Batteries contain sub-
stances that are very
harmful for the environ-
ment. You are advised to have the
battery changed at Alfa Romeo
Authorized Services, which are
properly equipped for disposing of
used batteries respecting nature
and the law.
POLLEN FILTER This has mechanical/electrostatic air fil-
tering actions, provided that the windows
and doors are shut.
Have the pollen filter checked once a year
by Alfa Romeo Authorized Services, prefer-
ably at the onset of summer.
If the car is mainly used in dusty or heav-
ily polluted areas, the filter should be
changed at more frequent intervals than
specified in the Scheduled Maintenance Pro-
gramme.
WARNINGThe failure to replace the fil-
ter can considerably reduce the effectiveness
of the climate control system.
fig. 23
A0B0147m
The liquid in the battery is
poisonous and corrosive.
Avoid contact with eyes and skin.
Do not bring naked flames or pos-
sible sources of sparks near to the
battery: risk of fire and explosion.

USEFUL HINTS TO EXTEND
THE LIFE OF YOUR BATTERYTo avoid quickly draining the battery and
to preserve its operating conditions over the
course of time, carefully follow the instruc-
tions below:
– The terminals must always be tightened.
– As far as possible, avoid keeping ser-
vices on for a long time with the engine
stopped (radio, hazard lights, parking lights,
etc.).
– When leaving the car parked in a
garage, make sure that the doors, bonnet,
boot and interior lids are properly shut to
prevent lights from staying on.
– Before doing any work on the electric
system, disconnect the battery negative ter-
minal.– If after purchasing the car, you wish to
install electrical accessories which need a
permanent electrical supply (alarm, hands-
free phone, radio-navigator with satellite an-
ti-theft function, etc.) contact Alfa Romeo
Authorized Services whose qualified per-
sonnel, in addition to suggesting the most
suitable devices from Lineaccessori Alfa
Romeo will be able to evaluate the total
electrical absorption, checking whether the
car’s electric system is able to support the
load required or whether a battery with high-
er capacity is necessary. In fact, these de-
vices continue to absorb current with the
ignition key off (car parked, engine off) and
may gradually drain the battery.
REPLACING THE BATTERYIf required, replace the battery with a gen-
uine spare part having the same specifica-
tions. If a battery with different specifica-
tions is fitted, the service intervals given in
the Programmed Maintenance Schedule in
this section will no longer be valid. Refer
to the instructions provided by the battery
manufacturer.

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.
