IMPORTANT If the sound system
or car alarm systems are not installed
correctly, they can interfere with the
working of the electronic control
units.
Modifications or repairs
to the electrical system
carried out incorrectly
and without bearing the features
of the system in mind can cause
malfunctions with the risk of fire.

ELECTRONIC
CONTROL UNITS
When the car is being used normal-
ly, special measures are not necessary.
The following instructions must be
followed very carefully however, if you
work on the electrical system or
where emergency starting is neces-
sary:
– Never disconnect the battery from
the electrical system while the engine
is running.
– Disconnect the battery from the
electrical system if you are recharg-
ing it. Modern battery chargers can
discharge voltage up to 20 V.
– Never perform emergency star-
tups with a battery charger. Always
use an auxiliary battery (see “Startup
with auxiliary battery” in “In an emer-
gency” chapter).– Be particularly careful when con-
necting the battery to the electrical
system. Make sure that the polarity is
correct and the connection is efficient.
After reconnecting the battery, the in-
jection/ignition control unit will need
to readapt its internal parameters.
Therefore, the car’s performance may
change slightly during the first few kilo-
meters.
– Do not connect or disconnect the
terminals of the electronic units while
the ignition key is at
MAR.
– Do not check polarity through
sparking.
– Disconnect the electronic units if
you are electrically welding the car
body. Remove the units if tempera-
tures exceed 80°C (special operations
on the bodywork etc.).

SPARK PLUGS
The cleanness and soundness of the
spark plugs
fig. 19 are 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 pinpointing a problem even if it
has nothing to do with the ignition sys-
tem. Therefore, if the engine has prob-
lems, it is important to have the spark
plugs checked at a
Fiat Dealership.
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 spec-
ified is not guaranteed, problems
can arise.

WHEELS AND
TYRES
TYRE 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 to restore the pressure
when the tyres are warm, remember
that the pressure value must be 0.3
bar above the specified value.
Tyre pressure must be
correct to ensure good
road holding.

Detergents pollute wa-
ter. The car must there-
fore be washed in an area
equipped for the collection and
purification of the liquids used
while washing.
IMPORTANT
The engine com-
partment should be washed while the
engine is cold and with the ignition key
at
STOP. After washing make sure
that the various protections (e.g. rub-
ber boots and various guards) have
not been removed or damaged.
IMPORTANTTo prevent damage
to the electric heater element, wipe the
inside of the heated rear window gen-
tly in the same direction as the ele-
ments.
Engine compartment
At the end of each winter season,
carefully clean the engine compart-
ment. Have this done at a garage.
INTERIORS
Periodically check that water has not
collected under the mats (from dip-
ping shoes, umbrellas etc.) which could
cause the steel to rust
CLEANING SEATS AND
FABRIC COMPONENTS
– Remove dust with a soft brush or
vacuum cleaner.
– Brush the seats with a damp
sponge with water and a neutral soap.
Never use flammable
products (petroleum
ether or petrol) to clean
the inside of the car. Electro-
static charges generated by rub-
bing while cleaning could cause
fires.
Do not keep aerosol
cans in the car. There is
the risk they might ex-
plode. Aerosol cans must never
be exposed to a temperature
above 50°C; when the weather
starts to get hot the temperature
inside the car might go well be-
yond that figure.
PLASTIC PARTS INSIDE THE
CAR
Use special products designed not to
alter the appearance of the compo-
nents.
IMPORTANTDo not use alcohol
or petrol to clean the glass of the in-
strument panel.
