CORRECT USE OF THE CAR
182
Tyres
Check the pressure of the tyres routinely at
an interval of no more than 4 weeks: if the
pressure is too low consumption levels in-
crease as resistance to rolling is higher. It
should be underscored that in these condi-
tions tyre wear increases and vehicle per-
formance is lower, therefore also its safety.
Useless loads
Never travel with an overload in the boot.
The weight of the vehicle (especially in ur-
ban traffic), and its geometry heavily affect
consumption levels and stability.
Luggage/ski racks
Remove the luggage rack or ski rack from
the roof as soon as they are no longer used.
These accessories lower air penetration and
adversely affect consumption levels. When
needing to carry particularly voluminous ob-
jects, preferably use a trailer.Electric services
Use electric devices only for the amount of
time needed. Rearscreen heating, addition-
al headlights, windscreen wipers and heater
fan need a considerable amount of energy
therefore, increasing the requirement of cur-
rent increases fuel consumption (up to
+25% in the urban cycle).
Climate control system
The climate control system is a further load
bearing heavily on the engine inducing high-
er consumption levels (up to +20% on av-
erage). Outside temperature permitting,
preferably use the air vents.
Aerodynamic items
The use of non-certified aerodynamic items
may adversely affect air drag and con-
sumption levels.DRIVING STYLE
Starting
Do not warm the engine with the car at a
standstill or at idle or high speed: under
these conditions the engine warms up much
more slowly, increasing electrical consump-
tion and emissions. It is therefore advisable
to move off immediately, slowly, avoiding
high speeds. This way the engine will warm
faster.
Pointless manoeuvres
Avoid accelerating when waiting at traffic
lights or before switching off the engine. This
and also double declutching is absolutely
pointless on modern cars and also increase
consumption and pollution.
Gear shifting
As soon as the conditions of the traffic and
road allow, use a higher gear. Using a low
gear to obtain brilliant performance increases
consumption. In the same way improper use
of a high gear increases consumption, emis-
sions and engine wear.

IN AN EMERGENCY
192
IT IS NECESSARY
TO KNOW THAT:
The sealer included in the quick repairing
kit, good for temperatures between –30°C
e +80°C, is not adequate for permanent fix-
ing.
The liquid inside the tyre can be easily re-
moved with water.
The sealer has no expire date.
It is not possible to fix
cracks on the tyre sides
and permanent sealing of cracks on
the tread within 25 mm from the
tyre side is not guaranteed.
WARNING
Do not use the quick re-
pairing kit if the tyre is
damaged due to driving with the
wheel flattened. That it is why it
is necessary to check accurately the
tyre sides.
WARNING
Do not operate the com-
pressor for more than 20
minutes: risk of overheating!
WARNING
In case of damages to the
wheel rim (the deformation
is such that there is an air leakage)
or the tyre outside the limit areas
previously indicated, fixing is not
possible. Do not remove foreign
bodies (screws or nails) which have
penetrated the tyre.
WARNING
Warning! The bottle (C-fig.
12) contains propylene gly-
col. This substance is toxic: do not
swallow it and avoid contact with
the eyes, the skin and the clothes.
In case of contact, rinse with abun-
dant water. If any allergy reaction
should take place call a medical doc-
tor. Keep the bottle cylinder in the
appropriate compartment away
from heat and children.

Incorrect pressure causes abnormal tyre
wear (fig. 11):
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.

IMPORTANT
Where possible, avoid suddent 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 necessary contact Alfa Romeo Au-
thorised Services.
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
itself, the rim, suspensions and steering sys-
tem. 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 personnel, to see
if they can still be used.In the case of replacement, always fit new
tyres, avoiding those of dubious origin.
The
Alfa 147 GTAuses Tubeless
tyres. Never use an inner tube with these
tyres.
If a tyre is changed, also change the infla-
tion valve.
To allow even wear between the front and
rear tyres it is advisable to change over every
10-15 thousand kilometres, keeping them
on the same side of the car so as not to re-
verse the direction of rotation (fig. 12).

Excessively low pressure
causes overheating of the
tyre with the possibility of serious
damage to it.

WINDSCREEN/
REARSCREEN WIPERS
BLADES
Periodically 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
rearscreen wipers on dry glass.
RUBBER HOSES
As 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 the prolonged lack of fluid in
the system may cause hardening and crack-
ing of the hoses, with possible leaks. Care-
ful 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 involving
temperatures exceeding
150°C should be avoided since
wheel mechanical characteristics
could be impaired.

ADVICE FOR PRESERVING
THE BODYWORK
Paint
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 “Body paint identi-
fication plate” in the “Technical Specifica-
tions” 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.Do not wash the vehicle 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.
IMPORTANTBird droppings must be
washed off immediately and thoroughly as
the acid they contain is particularly aggres-
sive.
Windows
Use specific products to clean the windows.
Use clean cloths to avoid scratching or al-
tering 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. 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 vehicle 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 chamois leather.
When drying, take particular care with the
less visible parts like door surrounds, bon-
net and around the headlights where wa-
ter may stagnate. The vehicle should not be
taken to a closed area immediately, but left
in the open so that residual water can evap-
orate.
