WHEELS
AND TYRES
TYRES PRESSURE
Every two weeks and before long
journeys, check the pressure of each
tyre including the spare.
The pressure must be checked when
the tyre is rested and cold.
It is normal for the pressure to rise
when you are driving. If you have to
check or restore the pressure when
the tyres are warm remember that the
pressure value must be 0.3 bar above
the specified value.
SPARK PLUGS
The cleanness and soundness of the
spark plugs fig. 9are very important
for keeping the engine efficient and
polluting emissions down.
The appearance of the spark plug, if
examined by an expert eye, is a good
way of pin-pointing a malfunction even
if it has nothing to do with the ignition
system. Therefore, if the engine has
problems, it is important to have the
spark plugs checked at a Fiat Deal-
ership.The spark plugs must be
changed at the times
specified in the Service
Schedule. Only use the type of
plugs indicated: if the heat ratio
is less than required or the life
specified is not guaranteed, prob-
lems can arise.

Wrong pressure causes uneven wear
of the tyresfig. 10:
A- Correct pressure: tyre wears
evenly.
B- Underinflated tyre: shoulder
tread wear.
C- Overinflated tyre: centre tread
wear.If you get a flat tyre, stop immediately
and change it so as not to damage the
tyre, the wheel, the suspension and
the steering.
Tyres age even if they are not used
very much. Cracking of the tread rub-
ber and the side-walls are a sign of this
ageing. In any case, if the tyres have
been fitted for more than six years
they should be examined by an expert
who can judge whether they are still
fit for use. Remember to check the
spare tyre particularly carefully too.
If a replacement is necessary, always
use new tyres and avoid using ones the
origin of which you are not certain
about.
The Fiat barchetta uses Tubeless
tyres. Under no circumstances use an
inner tube with these tyres.
If you replace a tyre it is a good idea
to change the inflation valve, too. Tyres must be replaced when the
tread wears down to 1.6 mm. Comply
with the laws in the country where the
car is being driven.
IMPORTANT
As far as possible avoid sharp brak-
ing and screech starts.
Be careful not to hit the pavement,
potholes or other obstacles hard. Dri-
ving 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 occur, have the car seen to at
a Fiat Dealership.
Avoid travelling with an overloaded
car: this can seriously damage wheels
or tyres.

If the pressure is too low
the tyre overheats and this
can cause it serious damage.

RUBBER TUBING
Follow the Service Schedule careful-
ly in the case of the braking, power
steering and fuel supply systems' rub-
ber hoses. Ozone, high temperatures
and long absence of liquid in the sys-
tem can in fact cause the hardening
and cracking of the hoses with possi-
ble losses of fluid. A careful check is
therefore essential.
WINDSCREEN
WIPER
BLADES
Periodically clean the rubber part
with suitable liquid; TUTELA PRO-
FESSIONAL SC 35is recommend-
ed.
Change the blades if the rubber edge
is warped or worn out. You should in
any case change them approximately
once a year. To ensure the front and rear tyres all
wear evenly, you are advised to change
the tyres over every 10-15 thousand
kilometres (6-10 thousand miles)
keeping them on the same side of the
car so as not to reverse the direction
of rotation.
Do not change the tyres
over in criss-cross fashion
by moving a tyre from the left hand
side of the car to the right and vice
versa.
WARNING
Travelling with worn wiper
blades is dangerous be-
cause it reduces visibility in bad
weather.
