VEHICLE MAINTENANCE

Incorrect pressure causes abnormal tyre
wear:
(A): Normal pressure: tread evenly
worn.
(B): Low pressure: tread particularly
worn at the edges.
(C): High pressure: tread particularly
worn in the centre.
Tyres should be changed when the tread
thickness is reduced to 1,6 mm.
In any case follow local regulations.
You are also reminded that services with
high current absorption switched on by the
user, such as for example: baby bottle
warmers, vacuum cleaner, mobile phone,
mini fridge, etc., quicken the battery
draining processif they are turned on
with the engine off or running at idle
speed.
IMPORTANT When installing addi-
tional systems on the vehicle, bear in
mind that improper branches on connec-
tions of the vehicle wiring are dangerous,
particularly if safety devices are involved.
WHEELS AND TYRES
TYRE PRESSURE
Check the tyre pressure of every wheel,
including the spare, 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; for the correct tyre
inflation pressure, see “Wheels” in the
“Technical Specifications” chapter.

The maximum absorption of all the
accessories (standard and fitted after-
wards) should be 0,6 mA x Ah (of the bat-
tery), as shown in the following table:

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
Warrantly Booklet.

VEHICLE MAINTENANCE

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.
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.
IMPORTANTThe vehicle should be
washed with the engine cold and the igni-
tion key at STOP. After washing make sure
that the various protections (e.g. rubber
caps and various covers) have not been
damaged or removed. Windows
Use specific products to clean the win-
dows. Use clean cloths to avoid scratching
or altering the transparency of the glass.
IMPORTANTThe inside of the
rearscreen should be wiped gently with a
cloth in the direction of the filaments to
avoid damaging the heating device.
Front headlights
IMPORTANTDo not use aromatic sub-
stances (e.g. petroleum) or ketones (e.g.
acetone) to clean the front headlight plas-
tic transparents.
Never use inflammable
products like fuel oil ether
or rectified petrol for
cleaning inside the car. The elec-
trostatic charges generated when
rubbing to clean may cause fire.
INTERIOR FITTINGS
Periodically check that water is not
trapped under the mats (due to water drip-
ping off shoes, umbrellas, etc.) which
could cause oxidisation on the sheet metal.
CLEANING SEATS AND FABRIC
AND VELVET PARTS
– Use a soft brush or a vacuum cleaner
to remove dust. Velvet is cleaned better if
the brush is moistened.
– Rub the seat with a sponge moistened
with a solution of water and neutral deter-
gent.
