120IN AN EMERGENCY
If the battery is flat, you can use an-
other battery to start the engine. Its
capacity must be the same or slightly
greater than the flat battery.
Proceed as follows fig. 1:
1) Connect positive terminals (+) of
the two batteries with a jump lead.
2)With a second lead, connect the
negative terminal (–) of the auxiliary
battery and to an earthing point E
on
the engine or the gearbox of the ve-
hicle to be started.
IMPORTANTDo not directly
connect the two negative terminals:
sparks could ignite the flammable gas
from the battery. If the other battery
is fitted in a vehicle, prevent acciden-
tal contacts between the metal parts
of the two vehicles.
3) Start the engine.
4)When the engine has been start-
ed, remove the leads reversing the or-
der above.If the engine fails to start after a few
attempts, do not keep turning the key
but have the vehicle seen to at a Fiat
Dealership.
JUMP STARTING

Do not carry out this
procedure if you lack ex-
perience; if it is not done
correctly it can cause very in-
tense electrical discharges. In ad-
dition, the fluid contained in the
battery is poisonous and corro-
sive. Avoid contact with skin and
eyes. You are also advised not to
put naked flames or lighted cig-
arettes near the battery and not
to cause sparks.
Under no circumstances
should a battery charger
be used to start the en-
gine: it could damage the elec-
tronic systems and in particular
the ignition and injection control
units.
166VEHICLE MAINTENANCE
ELECTRONIC
CONTROL UNITS
When the vehicle is being used nor-
mally, special measures are not neces-
sary.
The following instructions must be
followed very carefully, however, if
you work on the electrical system or
in cases where emergency starting is
necessary:
– 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. The modern battery chargers
can discharge voltage up to 20V.
– Never perform emergency start-
ups with a battery charger. Always use
an auxiliary battery.
– Be particularly careful when con-
necting the battery to the electrical
system. Ensure the battery posts are
connected up to the right leads (the Battery Maximum
admitted
stand-by intake
40 Ah 24 mA
50 Ah 30 mA
60 Ah 36 mApolarity is correct) and check that the
connection has been made properly.
– 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 vehi-
cle body. Remove the units if temper-
atures exceed 80°C (special opera-
tions on the bodywork, etc.).
IMPORTANTIf the sound system
or alarm systems are not installed cor-
rectly, 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.
The total intake of these systems
(factory and after-market) must be less
than 0.6 mA x Ah (of the battery) as
shown in the following table:
