VEHICLE MAINTENANCE

Alloy rim painting
involving temperatures
exceeding 150 °C should
be avoided since wheel mechani-
cal characteristics could be
impaired.Do not cross switch the
tyres, moving them from
the right of the car to the
left and vice versa.Excessive low pressure
causes overheating of the
tyre with the possibility
of serious damage to it.Remember that vehicle
road holding also depends
on correct tyre inflation
pressure.
RUBBER HOSES
As far as the brake system and fuel sup-
ply rubber hoses are concerned, carefully
follow the Scheduled Maintenance
Programme. Indeed, ozone, high temper-
atures and the prolonged lack of fluid in
the system may cause hardening and
cracking of the hoses, with possible leaks.
Careful control is therefore necessary. IMPORTANTS
– Where possible, avoid sudden brak-
ing, tyre squealing starts, violent bumps
against kerbs, potholes or obstacles of var-
ious kinds. Prolonged driving on rough
roads may damage the tyres;
– Routinely check the tyres for cuts on
the sides, swellings or uneven tread wear.
If necessary contact Alfa Romeo
Authorised Services;
– Avoid overloading the vehicle when
travelling: this may cause serious damage
to the wheels and tyres;
– If a tyre is punctured, stop immedi-
ately and change it to avoid damage to
the tyre itself, the rim, suspensions and
steering system;
– Tyres age even if they are not used
much. Cracks in the tread rubber are a
sign of aging. In any case, if the tyres
have been on the vehicle for over 6 years,
they should be checked by specialised per-
sonnel, to see if they can still be used.
Also remember to check the compact
spare wheel;
– In case of replacement, always fit new
tyres, avoiding those of dubious origin;

HEADLIGHT WASHERS
(fig.17)
Regularly check that the spray jets are
intact and clean.
If it is necessary to direct the jet, contact
an Alfa Romeo Authorised Service
BODYWORK
PROTECTION FROM
ATMOSPHERIC AGENTS
The 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
abrasive action of wind-borne atmospheric
dust and sand and mud and gravel raised
by other vehicles.
On your car Alfa Romeo has implement-
ed the best manufacturing technologies to
effectively protect the bodywork against
corrosion.
fig. 17
A0A0704b
These include:
– Painting products and systems which
give the vehicle particular resistance to
corrosion and abrasion.
– Use of galvanised (or pretreated)
steel sheets, with high resistance to corro-
sion.
– Spraying of the underbody, engine
compartment, wheel arches and other
parts with highly protective wax products.
– Spraying of plastic parts, with a pro-
tective function, in the more exposed
points: underdoor, inner wheel arch lin-
ings, etc.
– Use of “open” boxed sections to pre-
vent condensation and pockets of mois-
ture from triggering rust inside.
VEHICLE EXTERIOR AND
UNDERBODY WARRANTY
Alfa GTis guaranteed against perfo-
ration due to rust of any original element
of the structure or body. For the general
terms of this warranty, refer to the
