battery MASERATI GRANTURISMO CONVERTIBLE 2019 Owner's Guide

NOTE:
After an emergency staring, you
should contact anAuthorized
Maserati Dealer as the emergency
starting procedure will have to be
carried out every time you want to
start the engine.Auxiliary Jump-Start
Procedure
If your vehicle has a discharged
battery it can be jump-started using a
set of jumper cables and a battery of
another vehicle or by using a portable
battery booster. It is necessary to have
proper jumper cables in order to
connect the booster battery to the
remote posts of the discharged
battery. Booster cables have usually
positive and negative terminal clamps
and are identified by a different
sheath color (red = positive, black =
negative). Maserati provides on
request jumper cables created for its
models and content in a practical case.
NOTE:
The Authorized Maserati Dealer can
provide you with information about
the “Maserati Jumper Cables Kit”,
available in the “Genuine Accessories”
range.
Jump-starting can be dangerous if
done improperly so please follow the
procedures in this section carefully. NOTE:
When using a portable battery
booster pack, follow the battery
manufacturer’s operating instructions
and precautions.
CAUTION!
• To jump start a vehicle do not use a portable battery, a booster pack or
any other booster source with a
system voltage greater than 14 Volts
or damage to the battery, starter
motor, alternator or electrical system
of the vehicle with the discharged
battery may occur.
• Do not use a battery charger for emergency starting under any
circumstances. You could damage
the electronic systems, particularly
the control units managing the
ignition and fuel supply functions.
• If the battery is completely discharged when the windows are
fully raised, open the door with the
utmost care; do not close the door
again until it is possible to lower the
window.

WARNING!
• Using booster packs that have not
been checked, which could therefore
release a too high charging voltage
(higher than 14 V), in extreme
environmental conditions (for
example: closed areas or without
proper ventilation and temperatures
higher than 122°F/50°C or lower
than -4°F/-20°C) create the right
conditions for ignition which could
then cause the battery to explode.
Therefore you shall always perform
jump-starting operations using the
adequate tools and in the best
environmental conditions, taking all
necessary precautions.
• Do not attempt jump-starting if the
discharged battery is frozen. It could
rupture or explode during jump start
and cause personal injury.
• Do not carry out this procedure if
you have not done it before:
incorrect maneuvers can originate
high electrical discharges and even
cause the battery to explode.
• To avoid the risk of explosion or fire,
do not approach the battery with open flames or cigarettes that could
generate sparks.
NOTE:
If
you need to disconnect the battery
from the vehicle electrical system, see
“Maintenance - Free Battery” in
section “Maintenance and Care”).
Access the Battery
The battery is stored in the trunk.
• Open the trunk lid (see “Open and Close the Trunk Lid” in section
“Before Starting”).
• Remove any luggage from the trunk compartment.
• Remove the floor panel from the trunk compartment.
• Remove the inside covering panel from the battery compartment. Remove the cover from the right side
of the battery which protects the
positive pole.
Jump-Start Procedure
WARNING!
• The battery is secured to the vehicle
with a metal clamp (indicated in the
picture), so be extremely careful not
to let the clips on the end of the
cables come into contact with it.
• Remove any metal jewelry such as
watch bands or bracelets that might
make an inadvertent electrical
contact. You could be seriously
injured.
• Do not allow the vehicles involved in
the jump-starting operation to touch
each other as this could establish a
ground connection and cause
personal injury.
• Turn off the heater, radio, and all unnecessary
electrical accessories.
• Set the parking brake, shift the automatic transmission into P (Park)
and turn the key in the ignition
switch to STOP (OFF) position.
• If using another vehicle to jump start the battery, park the vehicle within

the jumper cables reach and set the
parking brake and make sure the
ignition is off.
• Connect one terminal clamp of the positive jumper cable to the positive
(+) pole of the discharged battery.
• Connect the opposite terminal clamp of the positive (+) jumper cable to
the positive (+) pole of the booster
battery.
• Connect one terminal clamp of the negative jumper cable to the
negative (–) pole of the booster
battery.
• Connect the opposite terminal clamp of the negative (–) jumper cable to
the negative (–) pole of the
discharged battery.
• Start the engine in the vehicle that has the booster battery, let the
engine idle a few minutes, and then
start the engine in the vehicle with the discharged battery. If using a
portable battery booster, wait a few
seconds after connecting the cables,
before starting the booster vehicle.
Once the engine is started, remove the
jumper cables in the reverse sequence.
• Disconnect the terminal clamp of the negative (–) jumper cable from the
negative (–) pole of the discharged
battery.
• Disconnect the opposite terminal clamp of the negative jumper cable
from the negative (–) pole of the
booster battery.
• Disconnect the terminal clamp of the positive (+) jumper cable from the
positive (+) pole of the booster
battery.
• Disconnect the terminal clamp of the positive jumper cable from the
positive (+) pole of the discharged
battery.
• After starting the engine of the vehicle with a discharged battery,
avoid turning it off immediately
because the engine running can help
recharge the battery if the latter is
not broken and if the charging
system is not faulty. NOTE:
If frequent jump-starting is required
to start your vehicle you should have
the battery and charging system
inspected at an
Authorized Maserati
Dealer.

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 flashers, 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
14°F/-10°C).
We recommend you to have the
battery
charge condition checked,
preferably at the beginning of the
cold season, to prevent the electrolyte
from 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 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
14.8 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
