Electronic Control Units

No special precautions are required for
the normal use of the car.
In case of repairs to the electrical
system or in an emergency starting, the
following instructions must be strictly
followed:
– Never disconnect the battery from
the electrical system when the
engine is running.
– Disconnect the battery from the
electrical system when recharging it.
WARNING When disconnecting the
battery, first detach the negative pole
terminal (-) and then the positive pole
one (+). When reconnecting the
battery, first attach the positive pole
(+) and then the negative one (-).
– Never carry out the emergency
starting procedure using a battery
charger: always use an auxiliary
battery.
– Take special care when connecting
the battery to the electrical system,
checking both for correct polarity
and for the connection efficiency.
– Never connect or disconnect the
Electronic Control Units terminals
when the ignition key is in the MAR
position.
– Do not check the electric polarities
through sparking.
– Disconnect the Electronic Control
Units when carrying out electric
weldings on the body. Remove them
if the temperature is over 80 °C
(special interventions on the
bodywork, etc.).
WARNING Incorrect installation or
modifications to the audio and alarm
systems may interfere with the proper
operation of the Electronic Control
Units.
WARNING Changes or repairs to the
electrical system carried out in an
incorrect manner or without taking
into account the technical
specifications of the system may cause
operating anomalies with the risk of
fire.

Spark plugs

It is essential that the spark plugs are
sound and clean for the engine to
work efficiently and to ensure that
polluting emissions are kept to a
minimum level.
WARNING The spark plugs must be
changed at the intervals specified in
the Scheduled Maintenance plan. Only
use the prescribed spark plugs: faults
may arise if the heat rating is
unsuitable, or if the specified duration
is not guaranteed.
