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.

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.

Use the Vehicle Tow Hook of
the Tool Kit
CAUTION!
The tow hook should only be used for
towing the car on flat roads. Do not
use the tow hook to remove the car
that is stuck on off road stretches.
The tow hook can also be used to tow
the
vehicle on the platform of a tow
truck.
It is necessary to inform the operators
of the rescue vehicle about the vehicle
minimum height to avoid, during its
loading, any contact of the lower ends
of the front or rear bumper with the
tow truck loading ramp.
The tow hook is contained in the tool
kit (see “Tool Kit” in this section) and
must be screwed in its seat accessible
behind the front grille, right-hand
side.
• Remove the protective cap by levering with the tip of a screwdriver
in the point shown in picture. • Carefully clean the threaded seat
before screwing the hook.
• Screw the tow hook into its seat for at least 11 turns.
NOTE:
Maximum work angle of towing cable
or bar: 15°.
Fuel Cut-out Inertia Switch
The vehicle is equipped with a safety
switch which activates in the event of
a collision, cutting off the fuel supply
and consequently causing the engine
to stop. It also prevents fuel spreading
if the fuel lines are damaged during
the accident.
Activation of the safety switch is
signaled by the illumination of the
warning light on the instrument
cluster display.
The switch is positioned underneath
the driver seat.
In order to operate the inertia switch,
lift the seat in the highest position.
WARNING!
After a collision, if you smell fuel or
note any leakage from the fuel supply
system, do not reactivate the switch
in order to prevent any fire risks.
The activation of the inertia switch
causes
all the doors and the trunk lid
to unlock, the lighting of the internal
domelight and the hazard warning
flashers.

Scheduled Maintenance
(Service) Indicator
When the deadlines for maintenance
Scheduled Maintenance services are
approaching, a message on the
instrument cluster display indicates
that service is due. The deadline may
be expressed in miles/Km or days,
whichever comes first.
The message is displayed only once,
upon activating the instrument cluster,
at decreasing intervals expressed in
mi/km (100, 50...... 1800, 1600,) or in
days (27, 24, ....... 6, 3), accompanied

Once the set limit in kilometers or the
expiry date is reached, every time the
instrument cluster is turned on
thereafter, the message “Service
coupon expired” will be displayed.Selecting the function “Service” in the
“Trip” menu of the MTC+, you can
display the next service deadline (see
“Onboard Computer (Trip)” in section
"Driving"). The residual mileage left
to the service deadline is always
indicated. The days remaining before
the scheduled service date instead, are
only indicated starting from the 511th
day (approximately 17 months).
NOTE:
Every time the battery is disconnected,
the date and time must be set (see
"MTC+ Settings" in section
"Dashboard Instruments and
Controls").

system updates the indication
“Scheduled service within... days”
automatically entering a later date
considering the maximum number of
days allowable for the next service
coupon.
