Maintenance and Care
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 trunk compartment
(see chapter "Tool Kit" section "In an
Emergency") and remove the battery
cover.
• 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
280
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.
Maintaining Battery Charge
If you perform short daily trips
(approximately 10 miles/16 km), which
correspond to an annual total of 4000
miles/6000 km, or when the vehicle is
not going to be used for one week or
more, Maserati recommends connecting
the vehicle to a battery charger, to save
you the trouble of having to recharge the
battery. The battery charger will keep
the battery charged properly and at the
correct voltage levels required by the
systems and devices in the vehicle.
Before using the battery charger,
carefully follow the instructions
provided.
If you do not use a battery charger to
prevent the battery from going flat
when you are not going to use the
vehicle for long periods of time, you
need to check and recharge the battery
at least once every three weeks. Make
this check if you perform short daily
trips (approximately 10 mi/16 km)
which correspond to an annual total
of 4000 miles/6000 km. Please note
that allowing the battery to go flat
repeatedly can cause premature wear on
the internal cells and greatly reduce their
life, leading to problems with the ignition
system and other electrical/electronic
systems.
