PROGRAMMEAn annual inspection programme
has been established for cars thet
cover less than 20,000 km (e.g.
10,000 km). It consists of the fol-
lowing:
– Check tyre conditions/wear and adjust
pressure if required (including the compact
spare wheel)
– Check lighting system operation (head-
lights, direction indicators, hazard lights,
boot lights, passenger compartment lights,
glovebox light, warning lights of instrument
panel, etc.)
– Check windscreen and rear-screen
wiper/washer operation, adjust nozzles
– Check windscreen/rear-screen blade po-
sition/wear
– Check condition and wear of the front
brake pad
– Check for bonnet and boot lock clean-
ness, lever cleanness and lubrication– Visually check the following: engine,
gearbox, transmission, piping (exhaust - fu-
el - brakes) rubber components (casings -
sleeves - bushings, etc..), brake and fuel
hoses
– Check battery charge condition
– Visually check the condition of the belts
and various controls
– Check and top up if necessary, the flu-
id levels (coolant, brake fluid, windscreen
washer fluid, battery, etc.)
– Change engine oil
– Replace engine oil filter

WARNING
Engine oil
Should prevailing use of the car be under
one of the following specially heavy condi-
tions:
– trailer or caravan towing
– dusty roads
– short distances (less than 7-8 km) re-
peated and with external temperatures be-
low zero.
– frequently idling engines or long distance
low speed driving (e.g. taxis or door-to-door
deliveries) or in case of a long term inac-
tivity.
Replace engine oil more frequently than
required on
SERVICE SCHEDULE
.WARNING
Fuel oil filter
The variety of the degree of purity of the
fuel oil in commerce may make it necessary
to change the fuel oil filter more frequently
than stated in the Scheduled Maintenance
Programme. If the engine is “sobbing” it
is a sign that the filter needs changing.WARNING
Air cleaner
Using the car on dusty roads, change the
air cleaner more frequently than stated in
the Scheduled Maintenance Programme.
For any doubts about the intervals be-
tween engine oil and air cleaner changes
in relation to how the car is used, contact
Alfa Romeo Authorized Services.

In the case of replacement, always fit new
tyres, avoiding those of dubious origin.
Alfa 156uses Tubeless tyres. Never
use an inner tube with these tyres.
If a tyre is changed, also change the in-
flation valve
To allow even wear between the front and
rear tyres, it is advisable to change them
over every 10-15 thousand kilometres,
keeping them on the same side of the car
so as to not reverse the direction of rotation
(fig. 26).
RUBBER HOSESAs far as the brake system and fuel sup-
ply rubber hoses are concerned, carefully fol-
low the Scheduled Maintenance Programme
of this chapter. Indeed ozone, high tem-
peratures and prolonged lack of fluid in the
system may cause hardening and cracking
of the hoses, with possible leaks. Careful
control is therefore necessary.
Do not cross switch the
tyres, moving them from
the right of the car to the left and
vice versa.
WARNING
Alloy rim painting involv-
ing temperatures exceed-
ing 150°C should be avoided since
wheel mechanical characteristics
could be impaired.

INTERIOR PLASTIC PARTSFor routine cleaning of interior plastic parts
use a soft cloth moistened with water and
neutral soap. Remove grease or persisting
stains using appropriate solvent-free prod-
ucts designed to preserve appearance and
colour of plastic components.
IMPORTANTNever use spirit or petro-
leum to clean the instrument panel or oth-
er plastic parts.
INTERIOR FITTINGSPeriodically check that water is not trapped
under the mats (due to water dripping off
shoes, umbrellas, etc.) which could cause
oxidisation of the sheet metal.
CLEANING SEATS AND FABRIC
AND VELVET PARTS – Use a soft brush or vacuum cleaner to
remove dust. Velvet is cleaned better if the
brush is moistened.
– Rub the seats with a sponge moistened
with a solution of water and neutral deter-
gent. CLEANING LEATHER SEATS– Remove dried on dirt with a lightly
moistened chamois leather or cloth with-
out pressing too hard.
– Remove liquid or grease stains with a
dry absorbent cloth without rubbing. Then
wipe with a soft cloth or chamois leather
with water and neutral soap. If the stain per-
sists, use specific products, carefully follow-
ing the instructions for use
WARNINGNever use spirit or alcohol-
based products.
Never use inflammable
products like fuel oil ether
or rectified petrol for cleaning in-
side the car. The electrostatic dis-
charges generated when rubbing to
clean may cause fire.
WARNING
Do not keep aerosol cans in
the car. There is the risk
they might explode. Aerosol cans
must never be exposed to a tem-
perature above 50°C. The temper-
ature inside the car might go well
beyond that figure when exposed
to the sun’s rays.

ODDMENTS COMPARTMENT (fig. 18-19)
On the sides of the boot there are two re-
cesses closed by a lid.
To open the cover, press button (A) and
turn it downwards. As optional for ver-
sions/markets where applicable, the odd-
ment compartment on the left-hand side can
be provided with CD-Changer.
When using the boot, nev-
er exceed the maximum
permissible loads given in the
“Technical specifications” chapter.
Also make sure that the items con-
tained in the boot are firmly se-
cured, to prevent them being
thrown forward and harming the
passengers in the event of abrupt
braking.
WARNING
Heavy luggage without
restraints could cause se-
rious harm to the passengers in an
accident.
WARNING
If you want to carry fuel in
a reserve can, you should
comply with legal regulations, on-
ly using a certified can suitably fas-
tened to the load retainer rings at
the corner of the boot. However,
remember that this increases the
risk of fire in the event of an acci-
dent.
