Maintenance and Care
CAUTION!
• Every time the battery is
reconnected, wait at least 30 seconds
with the ignition device turned to
RUN before starting the engine, in
order to allow the electronic system
that manages the motor-driven
throttles to run a self-learning cycle.
At the same time, you can run the
date and time set up procedure for
the MIA.
• Every time the battery is reconnected
the warning lights
flash for about 10 seconds then go
off.
Useful Advice to Extend
Battery Life
When parking the vehicle, make sure
that the doors, front, rear lids and
flaps are properly closed. All interior
lights should be off.
When the engine is turned off, do not
keep the connected devices switched
on for a long time (such as radio,
hazard warning lights, fan, etc.).

CAUTION!
If the battery charge remains below
50% for a long period of time, it will
be damaged due to sulfation; its
performance and starting power will
be reduced and it will be more subject
to freezing (this can happen even at
-10°C/14°F).
We recommend you to have the
battery charge condition checked,
preferably at the beginning of the cold
season, to prevent the electrolyte from
and
freezing.
This check should be carried out 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 when
the ignition device is off. This applies
above all if these devices have been
retrofitted ("Aftermarket" services). If
the vehicle is not used for long periods
of time, please see "Vehicle Stored for
Long Periods" in this section
Battery Recharge
WARNING!
The process of charging or recharging
the battery produces hydrogen, a
flammable gas that can explode and
cause serious injuries. When charging
or recharging the battery, follow the
recommended precautions at all times.
• Before using a charger device always
check that this tool is suitable for
the installed battery, with constant
voltage (lower than 14.8 V) and low
amperage (maximum limit 15 A).
• Recharge the battery in a well-
ventilated environment.
• Never charge or recharge a frozen
battery: it can explode due to
hydrogen trapped inside the ice
crystals.
• Ensure that any sparks or open
flames are kept well away from the
battery while it is charging.
• Before using a charger to charge or
maintain the battery charge status,
carefully follow the instructions
provided to ensure the charger is
connected to the battery safely and
correctly.
Is possible to recharge the battery
without disconnecting the cables of
the vehicle electrical system.
