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.

Level Checks
ENVIRONMENTAL!
• The engine oils and fluids used
contain substances that are
dangerous for the environment. For
replacement you are advised to
contact an Authorized Maserati
Dealer, where all the necessary
equipment is available to dispose of
the used oil and fluids in compliance
with the regulations in force and in
an environment-friendly manner.
• All equipment used for fluids
replacement (gloves, cloths,
containers, etc) must be disposed in
compliance with the regulations in
force.
Engine Coolant Level Check
Your vehicle has been equipped with
an improved engine coolant
(antifreeze) that offers high protection
against corrosion, freezing and allows
extended maintenance intervals. To
prevent reducing extended
maintenance periods, it is important to
use original engine coolant
(antifreeze) when adding coolant
throughout the life of your vehicle.
Maintenance and Care
7
240

When adding engine coolant
(antifreeze) use pure water only, such
as distilled or deionized water when
mixing the water/engine coolant
(antifreeze) solution. The use of
impure water will reduce the amount
of corrosion protection in the engine
cooling system.
• Mix a minimum solution of 50%engine coolant (antifreeze) and
distilled water. Use higher
concentrations (do not exceed 70%)
if temperatures below -35°F (-37°C)
are forecast.
Please note that it is the owner's
responsibility to maintain the proper
level of protection against freezing
according to the temperatures
occurring in the circulation area of the
vehicle.
The coolant tank provides a quick
visual method to determine that the
coolant level is adequate. As long as
the engine operating temperature is
satisfactory, the coolant bottle only
needs to be checked once a month.
With the engine off and cold, the level
of the coolant in the tank on the right
side of the engine compartment
should be between the MIN or MAX
reference notches indicated on the
tank. • When additional engine coolant
(antifreeze) is needed to maintain
the proper level, it should be added
to the coolant bottle after removing
the cap. Do not overfill.
• Once the desired level is reached, reassemble and firmly close cap of
the tank.
• If frequent engine coolant (antifreeze) additions are required,
or if the level in the coolant recovery
tank does not drop when the engine
cools, the cooling system should be
pressure-tested for leaks by a Service
Center
• Keep the front of the radiator and the condenser clean.
WARNING!
• Never add engine coolant
(antifreeze) when the engine is hot. Do not loosen or remove the cap of
the engine coolant bottle to cool a
hot engine. Heat causes pressure to
build up in the cooling system. To
prevent scalding or injury, do not
remove the pressure cap while the
system is hot or under pressure.
• When adding coolant do not use a
pressure cap other than the one
specified for your vehicle. Personal
injury or engine damage may result.

Brake Fluid Level Check
Check

the fluid level immediately if
the brake system
red warning
light and the related message turn on
indicating a low level of brake fluid.
• Clean the brake fluid reservoir area around the cap before removing it.
• Add fluid to bring the level up to the “MAX” mark on the side of the
master cylinder reservoir. Use only
manufacturer's recommended brake
fluid (see “Refillings” in section
"Features and Specifications").
• Once the correct level is reached, firmly close the cap.
The brake pads wear could cause the
fluid level to fall. However, low fluid
level may be caused by a leak and a requires accurate checkup of the
braking system.
CAUTION!
The symbol
on the tank cap
identifies the synthetic type of brake
fluid, distinguishing it from the
mineral type. Using mineral fluids
damages the special rubber linings of
the brake system irreparably.

WARNING!
• To avoid contamination from foreign
materials or moisture, use only new
brake fluid or fluid that has been in
a tightly closed container. Keep the
master cylinder reservoir cap secured
at all times. Brake fluid in an open
container absorbs moisture from the
air resulting in a lower boiling point.
This may cause it to boil
unexpectedly during hard or
prolonged braking, resulting in
sudden brake failure. This could
result in an accident.
• Overfilling the brake fluid reservoir
can result in spilling brake fluid on
hot engine parts, causing the brake
fluid to catch fire. Brake fluid can
also damage painted and vinyl
surfaces, make sure it does not spill
over these surfaces.
• Do not allow petroleum based fluid
to contaminate the brake fluid.
Brake seal components could be
damaged, causing partial or
complete brake failure. This could
result in an accident.
