for short trips or if it is equipped with
power-absorbing devices that remain
permanently on even when the
ignition switch 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
14.0 V) and low amperage
(maximum limit 15 A).
• Recharge the battery in a
well-ventilated environment.
• Never charge or recharge a frozen
battery. • 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.
It is possible to recharge the battery
without
disconnecting the
cables of
the vehicle electrical system.
• To access the battery lift the ground
coverage of the trunk compartment
and remove the access cover as
previously shown (see paragraph “To
Disconnect the Battery" in this
chapter).
• Remove the protection cover and
connect the terminal clamp of the
charger positive cable (typically in
red) to the positive post (+) of the
battery.
• Connect the terminal clamp of the
charger negative cable (typically in
black) to the nut located by the
negative post (-) on the battery,
indicated in the picture. The vehicle is equipped with an IBS
(Intelligent Battery Sensor) sensor able
to measure charging and discharging
currents and to calculate the state of
charge and state of health of the
battery. This sensor is located at the
negative post (-) of the battery.
For a successful charge/recharge
operation, the charging current must
flow through the IBS sensor as shown
in the picture.Maintenance and Care

compartment, do not direct the
water for too long directly on the module.
