Incorrect pressure causes abnormal tyre
wearfig. 15:
Anormal pressure: tread evenly worn.
Blow pressure: tread particularly worn
at the edges.
Chigh pressure: tread particularly worn
in the centre.
Tyres must be replaced when the tread
wears down to 1.6 mm. In any case,
comply with the laws in the country
where the car is being driven.
IMPORTANT NOTES
As far as possible, avoid sharp braking
and screech starts, etc. Be careful not to
hit the kerb, potholes or other obstacles
hard. Driving for long stretches over
bumpy roads can damage the tyres.
Periodically check that the tyres have no
cuts in the side wall, abnormal swelling
or irregular tyre wear. If any of these oc-
cur, have the car seen to at Alfa Romeo
Authorized Services.
Avoid overloading the car when travel-
ling: this may cause serious damage to
the wheels and tyres; if a tyre is punc-
tured, stop immediately and change it
to avoid damage to the tyre, the rim,
suspensions and steering system.
WHEELS AND TYRES
Check the pressure of each tyre, includ-
ing the space-saver spare wheel, every
four weeks and before long journeys:
pressure should be checked with the tyre
rested and cold.
For the correct tyre inflation pressure,
see “Wheels” in “Technical specifica-
tions” section.

Remember that road
holding depends also
on the correct tyre inflating
pressure.
WARNING
If the pressure is too
low the tyre overheats
and this can cause it serious
damage.
WARNING
Never submit alloy
rims to repainting
treatments requiring to use
temperatures exceeding
150°C since the mechanical
properties of the wheels could
be impaired.
WARNING
Do not cross switch the
tyres, moving them
from the right of the car to the
left and vice versa.
WARNINGTyres age even if they are not used
much. Cracks in the tread rubber are a
sign of ageing. 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 space-
saver spare wheel.
In the case of replacement, always fit
new tyres, avoiding those of dubious ori-
gin.
If a tyre is changed, also change the in-
flation valve; to allow even wear be-
tween the front and rear tyres, it is ad-
visable 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.

WINDSCREEN/REAR
SCREEN WIPERS
BLADES
Periodically clean the rubber part using
special products TUTELA PROFES-
SIONAL 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 fall below zero,
make sure that ice has not frozen the
rubber against glass. If necessary,
thaw using an antifreeze product;
❒ remove any snow from the glass: in
addition to protecting the blades, this
prevents effort on the motor and
overheating;
❒do not operate the windscreen wipers
on dry glass.
RUBBER HOSES
As far as the brake system and fuel rub-
ber hoses are concerned, carefully fol-
low the Service schedule in this section.
Indeed ozone, high temperatures and
prolonged lack of fluid in the system
may cause hardening and cracking of
the hoses, with possible leaks. Careful
control is therefore necessary.
Driving with worn
wiper blades is a seri-
ous hazard, because visibility
is reduced in bad weather.

SPRAY NOZZLES
If the jet of fluid is missing, firstly check
that there is fluid in the reservoir: see
“Checking fluid levels” in this section).
Then check that the nozzle holes are not
clogged, if necessary use a needle.
Fluid jets shall be directed at about 1/3
height from the window upper edge.
HEADLIGHT WASHERS
Regularly check that the spray jets are
intact and clean.
The headlight washers are automatical-
ly switched on when the windscreen
washer is operated and the dipped
beams are on.
Changing the windscreen
wiper blades fig. 16
How to remove the blade:
– raise the windscreen wiper arm A;
– turn the blade Bby 90° around pin
C, on the final section of the arm;
– remove the blade from the pin C.
How to refit the new blade:
– fit pin Cinto the hole in the middle
of the blade B;
– refit the arm with the blade on the
windscreen.

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 of plastic parts, with a pro-
tective function, in the more exposed
points: underdoor, inner fender parts,
edges, etc.;
❒Use of “open” boxed sections to pre-
vent condensation and pockets of
moisture from triggering rust inside.
BODY AND UNDERBODY
WARRANTY
Your car is covered by warranty against
perforation due to rust of any original el-
ement of the structure or body. For the
general terms of this warranty, refer to
the Alfa Romeo Warranty booklet.
BODYWORK
PROTECTION FROM
ATMOSPHERIC AGENTS
The main causes of corrosion are the fol-
lowing:
❒atmospheric pollution;
❒salty air and humidity (coastal areas,
or hot humid climates);
❒ seasonal environment conditions.
Not to be underestimated is also the
abrasive action of wind-borne atmos-
pheric dust and sand and mud and grav-
el raised by other cars.
On your car, Alfa Romeo implemented
the best manufacturing technologies to
effectively protect the bodywork against
corrosion.

Exterior plastic parts must be cleaned in
the same way as the rest of the car.
Where possible, do not park under trees;
the resinous substance many species re-
lease give the paint a dull appearance
and increase the possibility of triggering
rust processes.
IMPORTANTBird droppings must be
washed off immediately and thorough-
ly as the acid they contain is particular-
ly aggressive.

To wash the car correctly proceed as fol-
lows:
❒remove the aerial from the roof to
prevent damage to it if the car is
washed in an automatic system;
❒wash the body using a low pressure
jet of water;
❒wipe a sponge with a slightly soapy
solution over the bodywork, fre-
quently rinsing with the sponge;
❒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 wa-
ter can evaporate.
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.
ADVICE FOR PRESERVING
THE BODYWORK
Paint
Paintwork does not only serve an
aestethic purpose, but also protects the
underlying sheet metal.
In the case of deep scrapes or scores,
you are advised to have the necessary
touching up carried out immediately to
avoid the formation of rust. Use only
original paint products for touching up
(see “Bodywork paint identification
plate” in section “Technical specifica-
tion”).
Normal paint maintenance consists in
washing at intervals depending on the
conditions and environment of use. For
example, in highly polluted areas, or if
the roads are sprayed with salt, it is wise
to wash the car more frequently.
Detergents cause water
pollution. Therefore the
car should be washed
in areas equipped for collecting
and purifying the liquid used in
the washing process.

Front headlights
Front headlights shall be washed with
soft cloth moistened with water and car
detergent.
IMPORTANT Cleaning headlight lens-
es with a dry cloth will damage the
headlights with lack of performance as
a consequence. Solvents mat the lens-
es with lack of performance as a con-
sequence.
IMPORTANT When washing the front
headlights with a water monitor noz-
zle keep at least 2 cm away from the
lenses. Windows
Use specific window cleaner products. Use
also clean cloths to avoid scratching the
glass or damaging the transparency.
IMPORTANTThe inside of the
rearscreen should be wiped gently with
a cloth in the direction of the filaments
to avoid damaging the heating device.Engine compartment
At the end of the winter the engine com-
partment should be carefully washed,
without directing the jet against electronic
control units. Contact a specialised work-
shop to have this done.
IMPORTANT The car should be
washed with the engine cold and the key
removed from the ignition device. After
washing make sure that the various pro-
tections (e.g. rubber caps and various cov-
ers) have not been damaged or removed.

If the stain persists, use specific prod-
ucts, carefully following the instructions
for use.
IMPORTANTNever use spirit or al-
cohol-based products.
INTERIOR PLASTIC PARTS
Clean plastic parts with a cloth
mositened with water and non-abrasive
neutral detergent. To remove grease or
hard stains, use appropriate products de-
signed to preserve the appearance of
components.
IMPORTANTNever use spirit or pe-
troleum to clean the instrument panel
or other plastic parts.
INTERIORS
Periodically 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 de-
tergent.
CLEANING LEATHER SEATS
Remove dried on dirt with lightly moist-
ened chamois leather or cloth without
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.
Never use flammable
products like oil ether
or rectified petrol for cleaning
car interiors. Electrostatic dis-
charges generated by rubbing
during cleaning operations
could cause fire.
WARNING
Do not keep aerosol
cans in the car: they
might explode. Aerosol cans
must never be exposed to a
temperature above 50°C. The
temperature inside the car ex-
posed to the sun may go well
beyond that figure.
