Maintenance and Care
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: 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
8
connected to the battery safely and
correctly.
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 boot compartment
(see chapter "Tool Kit" section "In an
Emergency") and remove the storage
box.
• 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 a 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 in 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.
• Turn the charger on and follow the
instructions on its user manual to
completely recharge the battery.
• When the battery is recharged,
turn off the battery charger before
disconnecting it from the battery.
• Disconnect first the terminal clamp
of the charger black cable from the
battery and then the terminal clamp
of the red cable.
• Reassemble the protection cover
on the battery positive post and
the other parts removed for this
operation.
