WHEELS AND TYRESTYRES PRESSURECheck the pressure of each tyre, includ-
ing the compact spare wheel, every two
weeks and before a long journey.
The pressure should be checked with the
tyre rested and cold.
It is normal for the pressure to increase
when the car is in use. If you have to check
or restore the pressure when the tyres are
hot, bear in mind that the pressure should
be +0.3 bar compare with the specified rat-
ing.
For the correct tyre inflation pressure, see
“Wheels” in the “Technical specifications”
chapter.Incorrect pressure causes abnormal tyre
wear fig. 25:
A- Normal pressure: tread evenly worn.
B- Low pressure: tread particularly worn
at the edges.
C- High pressure: tread particularly worn
in the centre.

WARNINGS
Where possible, avoid sudden braking, tyre
squealing starts, etc.
Particularly avoid violent bumps against
kerbs, potholes or obstacles of various kinds.
Prolonged driving on rough roads may dam-
age the tyres.
Routinely check the tyres for cuts on the
sides, swellings or uneven tread wear. If nec-
essary contact Alfa Romeo Authorized Ser-
vices.
Avoid overloading the vehicle when trav-
elling: this may cause serious damage to the
wheels and tyres.
If a tyre is punctured, stop immediately
and change it to avoid damage to the tyre,
the rim, suspensions and steering system.
Tyres age even if they are not used much.
Cracks in the tread rubber are a sign of ag-
ing. In any case, if the tyres have been on
the car for over 6 years, they should be
checked by specialised personnel, to see if
they can still be used. Also remember to
check the spare wheel.
Remember that car road
holding also depends on
correct tyre inflation pressure.
WARNING
Excessively low pressure
causes overheating of the
tyre with the possibility of serious
damage to it.
WARNING
Tyres should be changed when the tread
thickness is reduced to 1.6 mm. In any case
follow local regulations.

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.

Proceed as follows:
– Raise the windscreen wiper arm and po-
sition the blade so that it forms an angle
of 90° with the arm.
– Press tab (B) of the coupling spring and
remove the blade to be replaced from the
arm (A).
– When the spring is released from the
curved top of the arm, move the blade to al-
low the arm to be withdrawn through the slot.
– Insert a new blade passing it through the
curved top of the arm (A) through the slot.
– Lift the blade to clamp tab (B) of the cou-
pling spring with the curved top of the arm.
– Lower the windscreen wiper arm.
WARNINGThe blades may differ ac-
cording to the versions. In any case, follow
the instructions provided in the packs avail-
able as spares from Alfa Romeo Authorized
Services. Changing the windscreen wiper
blade (fig. 27)
WARNINGThe blade on driver’s side
is fitted with a spoiler that improves adhe-
sion between the blade and the windscreen.
To prevent improper fitting, before changing
the blade, check the spoiler direction of the
blade to be replaced, then fit the new blade
following the same spoiler direction.

WINDSCREEN/REAR
SCREEN WIPERSBLADESPeriodically clean the rubber part using spe-
cial products TUTELA PROFESSIONAL
SC 35is recommended.
If the rubber blades are bent or worn they
should be replaced. In any case they should
be changed once a year.
A few simple notions can reduce the pos-
sibility of damage to the blades:
– If the temperature falls below zero,
make sure that ice has not frozen the rub-
ber against the glass. If necessary, thaw us-
ing an antifreeze product.
– Remove any snow from the glass: in ad-
dition to protecting the blades, this prevents
effort on the motor and overheating.
– Do not operate the windscreen and rear
window wipers on dry glass.
Driving with worn wiper
blades is a serious hazard,
because visibility is reduced in bad
weather.

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.

RECOMMENDATIONS
TO PRESERVE THE BODYWORKPaint
The paintwork does not only serve an aes-
thetic purpose but also protects the under-
lying sheet metal.
In the case of deep scrapes or scores, you
are advised to have the necessary touch-
ing up carried out immediately to avoid the
formation of rust.
Only original products should be used for
touching up paint (see “Bodywork paint
identification label” in the “Technical spec-
ifications” chapter).
Normal paint maintenance consists in
washing at intervals depending on the con-
ditions and environment of use. For exam-
ple, in highly polluted areas, or if the roads
are sprayed with salt, it is wise to wash the
car more frequently.
Detersives pollute water.
The car should therefore be
washed in areas equipped
for the collection and purification
of the liquid used in the washing
process.
To correctly wash the car:
1)Remove the aerial from the roof to pre-
vent damage to it if the car is washed in
an automatic system.
2)Spray the body with a low pressure
jet of water.
3)Pass a sponge moistened with a light
detergent solution, rinsing the sponge fre-
quently.
4)Rinse well with water and dry with a
jet of air or a chamois leather.
When drying, take particular care with the
less visible parts like door surrounds, bonnet
and around the headlights where water may
stagnate. The car should not be taken to a
closed area immediately, but left in the open
so that residual water can evaporate. – Spraying of plastic parts, with a pro-
tective function, in the more exposed
points: underdoor, inner wheel arch linings,
edges, etc.
– Use of “open” boxed sections to pre-
vent condensation and pockets of moisture
from triggering rust inside.
VEHICLE EXTERIOR AND
UNDERBODY WARRANTYThe Alfa 156is guaranteed against
perforation due to rust of any original ele-
ment of the structure or body. For the gen-
eral terms of this warranty, refer to the War-
ranty Booklet.

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.

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.
