“Trip” menu of the MTC+, you can
display the next service deadline (see
“Onboard Computer (Trip)” in section

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

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
well-ventilated area and wear gloves
or wash your hands frequently when
servicing your vehicle. For more
information go to:
www.P65Warnings.ca.gov/passenger-
vehicle
Heavy-Duty Vehicle Use
If the car is mainly used under one of
the following conditions:
• dusty roads;
• short, repeated journeys (less than
4-5 mi/7-8 km) at sub-zero outside
temperatures;
• engine often idling or driving long distances at low speeds or long
periods of idleness;
Maintenance and Care

you should perform the following
inspections more frequently than
recommended on the “Scheduled
Service Plan”:
• check front disc brake pad conditionsand wear;
• check cleanliness of hood and trunk locks, cleanliness and lubrication of
linkage;
• visually inspect conditions of: engine, transmission, pipes and hoses
(exhaust - fuel system - brakes) and
rubber elements (trunks - sleeves -
bushes - etc.);
• check battery charge;
• visually inspect condition of the accessory drive belts;
• check and, if necessary, change engine oil and replace oil filter;
• check and, if necessary, replace pollen filter of the A/C system;
• check and, if necessary, replace air cleaner filter.
CAUTION!
All maintenance operations for the
vehicle must be carried out by the
Authorized Maserati Dealer . For
routine and minor maintenance
operations which you can carry out yourself, make sure that you have the
necessary experience and always use
suitable equipment, original
Maserati
spare parts (or equivalent) and the
prescribed fluids. Shall this not be the
case, do not carry any operation on
your own and contact an Authorized
Maserati Dealer.
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 an
Authorized Maserati Dealer
for 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
the Authorized Maserati Dealer is
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.

Maintenance Procedures
The following pages contain the
“required” maintenance standards
determined by Maserati engineers.
Besides those maintenance items
specified in the “Scheduled Service
Plan”, there are other components
which may require service or
replacement in the future.
To perform most of the services, it is
necessary to open the hood (see
“Open and Close the Hood” in section
“Before Starting”).
The following images show the
position of all components involved in
the maintenance service.
CAUTION!
• Failure to properly maintain your vehicle or perform repairs and
service when necessary could result
in more costly repairs, damage to
other components or negatively
impact vehicle performance.
Immediately have potential
malfunctions examined by an
Authorized Maserati Dealer or a
qualified repair center.
• Your vehicle has been equipped with improved fluids that protect the
performance and durability of your vehicle and also allow extended
maintenance intervals. Do not use
chemical flushes for washing as the
chemicals can damage your engine,
transmission, power steering or air
conditioning. Such damages are not
covered by the New Vehicle Limited
Warranty. If a flush is needed
because of component malfunction,
use only a specific product for the
flushing procedure.

Adding Windshield/Headlight Washer
Fluid
The reservoir on the left side of the
engine compartment contains the
fluid to wash the windshield and
headlights.
During scheduled services or when the
message of low level of the washer
fluid appears together with the
related telltale add more fluid as
soon as possible.
The fluid reservoir may contain nearly
1.58 US gallons (6 liters) of
windshield/headlight washer fluid.
• Remove the reservoir cap in the engine compartment and lift the
filler neck extension.
• Fill the reservoir with windshield washer solvent (refer to “Refillings”
in section "Features and
Specifications") and operate the system for a few seconds to flush out
the residual water.
• When refilling the washer fluid reservoir, apply some washer fluid to
a cloth or towel and wipe the wiper
blades clean. This will help blade
performance.
To prevent freeze-up of your
windshield washer system in cold
weather, select a solution or mixture
that meets or exceeds the
temperature range of your climate.
This rating information can be found
on most washer fluid containers.
NOTE:
The Authorized Maserati Dealer can
provide you with information about
the “Maserati recommended
Windshield Washer Fluid” with
antifreeze, available in the “Genuine
Accessories” range.
WARNING!
• Commercially available windshield
washer solvents are flammable.
They could ignite and burn you.
Care must be exercised when filling
or when working around the
windshield/headlight washer
system. •
Do not drive with the windshield/
headlight washer reservoir empty:
the action of the washer is essential
for improving visibility when
driving.
