2019 MASERATI GRANTURISMO CONVERTIBLE key battery

Towing a Disabled Vehicle
Proper towing or lifting equipment is
required to prevent damage to your
vehicle. Use only towing bars and
other equipment designed for the
purpose, following equipment
manufacturer’s instructions.
Safety chains are mandatory.
Except for the front threaded seat to
fix the supplied hook (see “Tool Kit”
chapter in this section), the vehicle is
not equipped with other connection
points for towing operations with tow
truck.
CAUTION!
Any improper maneuver and use of
unsuitable equipment for recovering
vehicle in an emergency from off road
location could seriously damage the
vehicle. Contact the Authorized
Maserati Dealer or anyone having
suitable equipment and the required
expertise to safely and properly carry
out any required operations.
Make sure you comply with local
towing
regulations.
• If the vehicle's battery is discharged ,
it is necessary to shift the automatic
transmission out of the P (Park) Position and release the parking
brake (see “ Transmission Manual
Release of P (Park) position” and
“Emergency Release of the Parking
Brake” in this section).
• If the vehicle battery is still charged ,
turn off the engine and disengage
the parking brake manually (if
automatically engaged) by using the
command at the side of the
transmission shift lever (see “Parking
Brake” chapter in section “Driving”).
Shift then manually the transmission
out of P (Park) as described in
“Transmission Manual Release of P
(Park) Position” chapter of this
section. If you need to use the
accessories (wipers, defrosters, etc.)
while being towed, the key in the
ignition switch must be turned in
MAR (ON) position, do not use the
ACC position.
Vehicle Towing Conditions
Maserati only allows vehicle towing
either on a flatbed or with all four
wheels off the ground.
If flatbed equipment is not available,
and the transmission is still operable,
the vehicle may be flat towed (with all
four wheels on the ground) under the
following conditions. • The shift lever must be in N (Neutral).
• The distance to be traveled must not
exceed 30 mi (50 km ).
• The towing speed must not exceed 30 mph (50 km/h).
If the transmission is not operable, or
the vehicle must be towed faster than
30 mph (50 km/h ) or farther than 30
mi (50 km) (for example on a
highway), tow with the rear driving
wheels off the ground and on a
platform of a rescue vehicle, or with
the rear wheels raised using a wheel
lift.
CAUTION!
If you have to tow the vehicle with 2
wheels raised, ensure that the key in
the ignition switch is in the STOP (OFF)
position. If this is not observed, when
the ESC is active, the ECU will store a
malfunction and the relative indicator
light
will illuminate on the
instrument cluster display. This
requires the intervention of an
Authorized Maserati Dealer to reset
the system.

quick coupling from the negative
pole (–) of the battery.
If the battery needs to be removed
from
its compartment, you must first
detach the terminal clamp from
negative pole (–) and then the other
terminal clamp from positive pole (+),
after removing the protective cover.
Battery poles are marked positive (+)
and negative (–) and are identified on
the battery case.
Remove the metal clamp indicated in
the picture and then remove the
battery from the trunk compartment.
To Reconnect the Battery
NOTE:
When the battery cables have been
disconnected and the trunk lid has
been locked, it is necessary to pull the
emergency release cable in order to
re-open it. To access the trunk and
operate the emergency release (see
“Open and Close the Trunk Lid”
chapter in section “Before Starting”).
CAUTION!
• It is essential when replacing the cables on the battery that the
positive cable is precisely attached to
the positive pole (+) and the
negative cable is attached to the
negative pole (–).
• Cable clamps should be tight on the terminal poles and free of corrosion.
After the battery has been
disconnected
and re-connected and
before starting the engine it is
necessary to proceed as follows:
• Unlock and lock the doors using the radio control buttons on the key.
• Unlock the trunk lid with the radio control button on the key and then
lock it manually. • Check the seats are working
correctly: in the event of
malfunction, carry out the
initialization operations described in
the chapter “Front Seats” of the
section “Understanding the Vehicle”.
• Initialize the climate control system by activating the compressor as
described in chapter "Air
Conditioning Controls" of the section
“Dashboard Instruments and
Controls”.
• Turn on the MTC+ and set the date and time (see “MTC+ Setting” in
section “Dashboard Instruments and
Controls”).
• Lift, release and lift again the lever located next the shift lever to
initialize the electric parking brakes.
In this way the
warning light
on the instrument cluster will turn
off.
CAUTION!
• Every time the battery is reconnected, wait at least 30 seconds
with the key in the ignition switch
turned to MAR (ON) position before
starting the engine, in order to allow
the electronic system that manages
the motor-driven throttles to run a

carbon monoxide which is strongly
toxic and potentially lethal.
WARNING!
California Proposition 65
Operating, servicing and maintaining
a passenger vehicle or off-road vehicle
can expose you to chemicals including
such as, engine exhaust, carbon
monoxide, phthalates and lead, that
which are know to the State of
California to cause cancer and birth
defects or other reproductive harm. To
minimize exposure, avoid breathing
exhaust, do not idle the engine except
as necessary, service your vehicle in a

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 the STOP (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 and that 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
