MAINTENANCE
WARNING: If the battery charge remains
below 50% for a long period of time, it will be
damaged due to sulphating: this will reduce its
performance and starting power and the battery
will be more subject to freezing (this can happen
even at -10°C).We recommend that you have the battery charge
condition checked, preferably at the beginning of
the cold season, to prevent the electrolyte from
freezing.
This check should be performed more frequently
if the vehicle is used mainly for short trips or if it
is equipped with power absorbing devices that
remain permanently on even if when the ignition
key is removed. This applies above all if these
devices have been fitted “after market”.
If the vehicle is not used for long periods of time,
please refer to chapter “If the vehicle is laid up
for long periods”, in this section.WARNING: If additional systems have to be
fitted in the vehicle, there is the risk of creating
dangerous branches on the electric wiring, in
particular if the safety devices are involved.
ELECTRONIC
CONTROL UNITSNo special precautions are required for the
normal use of the vehicle.
In the event 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 (see page 168
“If the battery is fl at”). WARNING: When the battery is disconnected,
you must first detach the negative pole terminal
(–) and then the positive pole one (+).
WARNING: The battery is secured inside the
vehicle by means of a metal box, therefore, be
extremely careful not to let the battery charger
clips come into contact with it.WARNING: When the battery is reconnected,
you must first attach the positive pole (+),
remembering to cover it with the cap provided,
and then the negative one (–).
- Never perform 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 that polarity is correct and that the
connection is properly working.
- Do not connect or disconnect the terminals
of the ECUs when the ignition key is at
MAR.
- Do not check the electric polarities through
sparking.
- Disconnect the ECUs in the event of
electrical welding on the vehicle body.
Remove them if the temperature is
over 80°C (special interventions on the
bodywork, etc.).
