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 .

vehicle 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.

• 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. WARNING!

Scheduled Maintenance
Service Correct maintenance is clearly the best
way to guarantee vehicle performance
and safety features, ensure respect for
the environment and low operating
costs.
NOTE:
Also remember that the scrupulous
observance of the maintenance
procedures is essential for keeping
your vehicle operating properly. Not
adhering to the “Scheduled Service
Plan” can impact your vehicle’s
warranty.
Interval Running Coupons Maserati has therefore provided for a
series of checks and maintenance
operations involving the 1 st
service
when the vehicle mileage reaches
12500 mi (20000 km) or after 2 years of
the vehicle's life, and subsequently
every 12500 mi (20000 km) or every 2
years.
After the 12 th
service, maintenance
must be restarted with the operations
scheduled for the 1 st
,2 nd
and 3 rd
service. CAUTION!
The Scheduled Maintenance services
are prescribed by the Manufacturer.
Failure to have the services carried out
can affect your warranty.
The Scheduled Maintenance service is
provided
by the whole Authorized
Maserati Dealer . In the event that,
when a service is performed, further
replacements or repairs are found to
be necessary in addition to the
scheduled operations, these can be
carried out only with the specific
consent of the Customer.
CAUTION!
You are advised to notify the
Authorized Maserati Dealer of any
minor operating problem, without
waiting for the next scheduled service.
NOTE:
• Change
your vehicle's oil if it has
been 2 years since your last oil
change.
• Change your engine oil more often if
you drive your vehicle off-road for an
extended period of time or short trips without reaching operation
temperature.
• Under no circumstances should oil
change intervals exceed 12500 mi
(20000 km) or at least after 2 years.
CAUTION!
Failure to perform the required
maintenance items may result in
damage to the vehicle.
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
by the
specific symbol.Maintenance and Care

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"). CAUTION!
• Failure to reset the system may cause
it to malfunction and indicate wrong
maintenance service intervals.
• If you incorrectly set a date earlier
than the last service coupon, the
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.Maintenance and Care

Scheduled Service Plan The Scheduled Maintenance services
listed in this chapter must be done
within the times or mileages specified
to protect your vehicle warranty and
ensure the best vehicle performance
and reliability.
More frequent maintenance may be
needed for vehicles in severe operating conditions, such as dusty
areas and very short trip driving.
Inspection and service should also be
done anytime a malfunction is
suspected.
Maserati recommends that these
maintenance intervals be performed at
the Authorized Maserati Dealer . The technicians at your dealership know
your vehicle best, and have access to
factory-approved information,
genuine Maserati parts, and specially
designed electronic and mechanical
tools that can help prevent future
costly repairs.
