Battery Statement
Battery Statement Status of
Charge
To avoid problems with ignition and/or
the electrical system in general when
you are driving, the battery charge
status is constantly maintained and
guaranteed by the vehicle's recharge
circuit; the main component of which
is the alternator. This circuit is only
able to supply voltage to the battery
when the vehicle is traveling.
The
warning light on the
instrument cluster (see “Instrument
Cluster” in section “Dashboard
Instruments and Controls”), will
indicate any malfunctions in the
recharge circuit or an insufficient
battery charge status (flashing).
The vehicle is fitted with advanced
electronic systems, such as, for
example, the alarm system and various
electronic control modules, which
consume power even when the key in
the ignition switch is in theSTOP (OFF)
position and the vehicle is not being
used.
Therefore, it is fundamental that the
battery is properly charged to ensure
that the engine starts properly andthat all the electrical/electronic systems
in the vehicle work efficiently.
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 (see
“Battery Charge Maintainer
Operation” in this chapter).
The battery charge maintainer 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 charge
maintainer, carefully follow the
instructions provided.
If you do not use a battery charge
maintainer to prevent the battery
from going dead 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
Maintenance and Care

270

miles/6000 km. Please note that
allowing the battery to go dead
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.
TheAuthorized Maserati Dealeris
available to advise you on how to
recharge your battery correctly and
give you useful information on battery
care and maintenance.
NOTE:
TheAuthorized Maserati Dealercan
provide you with any information
about the Maserati approved “Battery
Charger and Conditioner”, available in
the “Genuine Accessories” range.
WARNING!
The process of charging or recharging
the battery produces hydrogen, a
dangerous gas that can explode and
cause serious injuries. When charging
or recharging the battery, follow the
recommended precautions at all
times:
•always charge or recharge the
battery in a well-ventilated
environment;•never charge or recharge a battery
that has frozen: it can explode due
to hydrogen trapped inside the ice
crystals;
•ensure that any sparks or open
flames are nowhere near 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.
Battery Charge Maintainer
Operation
Charge Maintainer Socket
Charge maintainer socket is located
inside the trunk compartment, on the
right-hand side.NOTE:
TheAuthorized Maserati Dealercan
give you all details concerning the
battery charge maintainer, available
from the "Genuine Accessories" range
with four types of socket, and its use.
Instructions for Use
First connect the battery charge
maintainer to vehicle socket: this
trigger the “Active” stage and the
maintainer can stay connected to
vehicle for a few months with no
problem.

WARNING!
Set the battery maintainer in view,
away from any heat source and out of
reach of children.
Battery charge maintaining process
can be stopped at any time by
disconnecting the power cable from
the mains.
Always disconnect the power cable
mains end first and then remove it
from vehicle socket.
The battery maintainer features three
LED identified by the following
symbols:
: error light;
: active stage light: indication;
: maintaining light: charge
maintenance.When LED
is steady on: it indicates
a fault of the vehicle electric system or
battery.
When LED
is steady on: it indicates
that maintainer is in “Active” stage. At
this stage the battery is brought from
a poor charge level to an excellent
charge level.
When LED
is steady on: it indicates
that the battery is fully charged and
maintainer is in “Passive” stage. At this
stage the device keeps battery charged
to an excellent level.
When LED
and LEDare
alternatively blinking:
• if they blink a few times per second,
probably the battery is sulfated;
• if blinking continues for over 60
minutes, the battery must be
replaced;
• if they blink with an interval of a few
minutes, it means that the
percentage of battery self-discharge
is considerable and it might be
necessary to replace it.
When no light is on, you might find
the following scenarios:
• maintainer cables are disconnected;
• the battery is not duly connected to
vehicle system;
• the battery is faulty;• battery voltage is insufficient or
simply there is no power at the mains
socket.
Check maintainer connections (to
mains and vehicle socket) and power
availability at the mains socket; if LED
or LEDfor “Active” or
“Passive” stage does not turn on
within a few seconds from proper
maintainer connection, contact an
Authorized Maserati Dealerto have
vehicle electrical system inspected.
Precautions and Warnings
