– Do not check for current in the cables by
short-circuiting the ends.
– If electric welding is to be carried out on
the body, remember to disconnect the elec-
tronic control units, or remove them if the
work involves high temperatures.ELECTRONIC
CONTROL UNITS
With normal use of the vehicle. no partic-
ular precautions need to be taken.
In the event of work on the electric system
or emergency starting, the instructions giv-
en below must absolutely be adhered to:
– Always switch off the engine before dis-
connecting the battery from the electric sys-
tem.
– If it is necessary to charge the battery,
always disconnect it from the electric sys-
tem.
– When starting in an emergency, only
use an auxiliary battery and not a battery
charger.
– Check that the bias is correct and that
the connections between the battery and
the electric system are in efficient conditions.
– Before disconnecting or connecting the
terminals of electronic units, ensure that the
ignition key is not in the MARposition.
WHEELS AND TYRES
TYRE PRESSURE
Check the tyre pressure of every wheel, in-
cluding the spare.
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. Should it become
necessary to restore the pressure with the
tyre hot, bear in mind that the pressure
should be +0.3 bar compared with the spec-
ified rating.
For the correct tyre inflation pressure, see
wheels in the “Technical Specifications”
chapter.
Alterations or repairs to
the electric system carried
out incorrectly and without taking
account of the specifications of the
system, may cause operating faults
with the risk of fire.
WARNING
Remember that vehicle
road holding also depends
on correct tyre inflation pressure.

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.

blade(fig. 13)
Instructions for removing the
windscreen wiper blade
Proceed as follows:
– raise the windscreen wiper arm (A);
– turn blade (B) 90° around pin (C), set
at the end of the arm;
– remove the blade from pin (C).Instructions for refitting the
windscreen wiper blade
To refit the blade proceed as follows:
– fit pin (C) into the hole located at the
middle of the blade (B);
– place the arm with the blade on the
windscreen.
Changing the rearscreen blade
(fig. 14)
– Raise the cover (A) and remove the arm
from the car, slackening the nut (B) that
fastens it to the pivot pin.
– Correctly position the new arm and firm-
ly tighten the nut.
– Lower the cover.

SPRAY JETS (fig. 15-16)
If the jet of fluid is inadequate, firstly check
that there is fluid in the reservoir: see
“Checking levels” in this chapter.
Then check that the nozzle holes are not
clogged, if necessary use a needle.
If necessary, direct the jet of fluid work-
ing on the adjustment screw (A).

Driving with worn wiper
blades is a serious hazard,
because visibility is reduced in bad
weather.

CLEANING LEATHER SEATS
– Remove dried on dirt with a lightly
moistened chamois leather or cloth with-
out pressing too hard.
– Remove liquid and 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.
IMPORTANTNever use alcohol. Make
sure that cleaning products do not contain
alcohol and alcohol derivatives even at low
strength.
INTERIOR PLASTIC PARTS
Use appropriate products designed to pre-
serve the appearance of components.
IMPORTANTNever use spirit or petro-
leum to clean the instrument cluster. 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 FITTINGS
Periodically check that water is not trapped
under the mats (due to water dripping off
shoes, umbrellas, etc.) which could cause ox-
idisation of the sheet metal.
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 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.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.
Never use inflammable
products like fuel oil ether
or rectified petrol for cleaning inside
the car. The electrostatic charges
generated when rubbing to clean
may cause fire.
WARNING
Do not keep aerosol cans in
the car. They might ex-
plode. Aerosol cans must never be
exposed to a temperature above
50°C. The temperature inside the
car exposed to the sun may go well
beyond that figure.

CONSUMPTION ACCORDING TO EEC 1999/100/ (litres x 100 km)
FUEL CONSUMPTION
The fuel consumption values shown in the
following tables were established during ho-
mologation tests prescribed in specific Eu-
ropean Directives.
The test conditions adopted include the fol-
lowing:
–an urban cycle: this includes cold
starting followed by simulation of a mixed
urban route;–an extraurban cycle: this includes
frequent accelerating in all gears, simulat-
ing normal extraurban use of the vehicle;
the speed varies between 0 and 120 kph;
–combined consumption: this is cal-
culated by considering a route consisting of
about 37% urban cycle and 63% extraur-
ban cycle.WARNING The type of route, traf-
fic conditions, weather conditions,
driving style, conditions of the ve-
hicle, trim level/equipment/ acces-
sories, vehicle load, presence of roof
rack, use of the climate control sys-
tem, other items that negatively af-
fect the aerodynamics of the vehi-
cle or wind resistance lead to dif-
ferent fuel consumption levels than
those measured by the above-men-
tioned procedures (see “Reducing
running costs and environment pol-
lution“ in the chapter “Correct use
of the car“).
