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
stservice
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
thservice, maintenance
must be restarted with the operations
scheduled for the 1
st,2ndand 3rd
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 wholeAuthorized
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 Dealerof 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 shorttrips 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.

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.

Onboard Diagnostic System
Your vehicle is equipped with a
sophisticated onboard diagnostic
system. This system monitors the
performance of the emissions, engine,
and automatic transmission control
systems. When these systems are
operating properly, your vehicle will
provide excellent performance and
fuel economy, as well as engine
emissions suited to current
government regulations.
If any of these systems require service,
the system will turn on the
Malfunction Indicator Light on the
instrument cluster display (refer to
“Instrument Cluster” in section
“Dashboard Instruments and
Controls”). The system stores as well
diagnostic codes and other
information to assist your service
technician by performing repairs.
Although the vehicle will be driveable
and will not need towing, contact anAuthorized Maserati Dealerfor service
as soon as possible.
CAUTION!
• Prolonged driving with the
MIL
on could cause further damage to
the emissions control system. It could
also affect fuel economy and
drivability. The vehicle must be
serviced before any emissions tests
can be performed.
•Ifthe
MIL is flashing while the
engine is running, severe catalytic
converter damage and power loss
will soon occur. Immediate service at
theAuthorized Maserati Dealeris
required.
Spare Parts
Use of genuine parts for normal or
scheduled maintenance and repairs is
highly recommended to ensure
excellent performance.
Damage or failures caused by
non-genuine spare parts used for
maintenance and repairs will not be
covered by the manufacturer's
warranty.
