recommended on the “Scheduled
Service Plan”:
• check front disc brake pad conditions
and 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

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 usesuitable equipment, originalMaserati
spare parts (or equivalent) and the
prescribed fluids. Shall this not be the
case, do not carry any operation on
your own and contact anAuthorized
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 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.

• Return the cap and dipstick to their
position and wait for a few minutes
to allow the oil to reach the oil pan.
• Check the level again.
After topping up, the
engine oil
level warning light may not go off for
some time while the system is
performing the necessary checks. This
is normal.
Engine Oil Filter Replacement
The engine oil filter should be
replaced with a new filter at every oil
change.
Contact anAuthorized Maserati
Dealerto perform this service.
Automatic Transmission Oil Check
Contact anAuthorized Maserati
Dealerfor the oil level check.
Power Steering Fluid Level Check
With the vehicle on a level ground
and the engine cold, check the fluid
level of the power steering reservoir.
• To carry out the check, unscrew the
cap, clean the dipstick with a dry and
clean cloth.
• Retighten the cap then unscrew it
again and check the level: it should
match the “MAX” notch marked on
the dipstick. In hot oil conditions,the level may even exceed the
“MAX” notch.
• If necessary, top up with fluid
making sure that it has the same
characteristics as the one already
used in the system (refer to
“Refillings” in section “Features and
Specifications”).
CAUTION!
Make sure that the power steering
fluid does not come in touch with the
engine hot parts as it is flammable.
Engine Air Filter Replacement
Contact anAuthorized Maserati
Dealerto have the air filters replaced.
Wiper Maintenance and Blades
Replacement
WARNING!
It is dangerous to operate or service
the wiper blades with the wipers in
an active position (right multifunction
lever in any position different than
“OFF”) and with the key in the
ignition switch in the MAR (ON)
position. The rain sensors may
suddenly activate the wipers.
Windshield Wiper Maintenance
Life expectancy of wiper blades varies
depending on the geographical area’s
weather conditions where the car is
used and frequency of use. Poor
performance of blades may be present
with chattering, marks, water lines or
wet spots. If any of these conditions
are present, clean the wiper blades or
replace if necessary.
Clean the rubber edges of the wiper
blades and the windshield periodically
with a sponge or soft cloth and a mild
nonabrasive cleaner. This will remove
accumulations of salt or road film.
Operation of the wipers on dry glass
for long periods may cause
deterioration of the wiper blades.

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
WARNING!
•Use only refrigerants and
compressor lubricants approved by
the manufacturer for your air
conditioning system. Some
refrigerants are flammable and can
explode, causing injuries. Other
unapproved refrigerants or
lubricants can cause the system to
fail, requiring costly repairs.
•The air conditioning system contains
refrigerant under high pressure. To
avoid risk of personal injury or
damage to the system, adding
refrigerant or any repair requiring
lines to be disconnected should be
done by an experienced technician.
Periodically remove any leaves and
insects that may build up and obstruct
the inlet of external air in the air
conditioning system through the grille
present underneath the rear part of
the hood.
To access the grille, lift the hood as
described in “Open and Close the
Hood” in section “Before Starting”.
A/C Air Filter Replacement
This filter performs mechanic/
electrostatic air filtering, provided
that windows and doors are perfectly
closed.
Have your filter replaced at least once
a year at anAuthorized Maserati
Dealer, preferably at the beginning of
the summer period.
If the vehicle is mainly used in the city
traffic, on highways or dusty roads, we
recommend that you replace the
filters more frequently than prescribed
in the "Scheduled Service Plan" of this
section.
CAUTION!
Failure to replace the filter may
considerably reduce the air
conditioning and heating system
efficiency.

Restarting the Vehicle
Before restarting the vehicle after a
long period of inactivity, we
recommend that you carry out the
following operations.
• Check the tires for pressure and for
any damages, cuts or cracks. If this is
the case, have them replaced.
• Do not dry-rub the external surface
of the vehicle.
• Visually inspect if there are any fluid
leaks (oil, brake and clutch fluid,
engine coolant etc.).
• Have the engine oil and filter
replaced.
• Check the fluid levels in the brake
system, as well as the engine coolant
level.
• Check the air filter and have them
replaced if necessary.
• Reconnect the battery after checking
the charge status (refer to
“Maintenance-Free Battery” in this
section) and perform the initializing
procedure if applicable.
• With the transmission in N (Neutral),
let the engine idle for several
minutes.WARNING!
The engine idle must be performed
outdoors. Exhaust gases contain
carbon monoxide which is strongly
toxic and potentially lethal.

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 theSTOP (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
