Level Checks ENVIRONMENTAL!
• The engine oils and fluids used
contain substances that are
dangerous to the environment. For
replacement you are advised to
contact the 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 of
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. 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 bottle 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 bottle on the left
side of the engine compartment
should be between the ranges
indicated on the bottle and inside the
filler neck. • 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 bottle.
• If frequent engine coolant
(antifreeze) additions are required,
or if the level in the coolant recoveryMaintenance and Care

NOTE:
The Authorized Maserati Dealer can
provide you with information about
the Maserati recommended
“Windshield Washer Fluid” with
antifreeze, available in the “Genuine
Accessories” catalog.
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.
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 known 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:

Engine Oil Level Check
T
o assure proper lubrication of your
vehicle's engine, the engine oil must
be maintained at the correct level.
If the
warning light illuminates
and the related message of low oil
level displays, or during scheduled
services (see “Scheduled Maintenance
Service” in this section) it is necessary
to check the engine oil level.
The best time to check the engine oil
level is about five minutes after a fully
warmed up engine is shut off or
before starting the engine after it has
sat overnight. In both cases the vehicle
should be parked on level ground to
improve the accuracy of the oil level
readings. CAUTION!
• Do not top up with oil with different
characteristics than the engine one
(refer to “Refillings” in section
“Features and Specifications”).
• Overfilling or underfilling the oil pan
will cause aeration or loss of oil
pressure. This could damage your
engine.
• Do not add any supplemental
materials to the engine oil. Engine
oil is an engineered product, and its
performance may be impaired by
supplemental additives.
• Remove the inspection cover on the
right
engine bank (3.8
V8 Engines, in
picture GTS Version).
• Remove the dipstick and clean it
with a dry and clean cloth. 3.8 V8 EnginesMaintenance and Care

• Re-insert the dipstick completely and
remove: the oil level should maintain
between the “MIN” and “MAX”
reference ranges (SAFE range). • If a refilling is necessary: unscrew the
filler neck cap.
• Adding 1.6 Quarter /1.4 Liters (3.8 V8
Engines) or 1 Quart /1 Liter (3.0 V6
Engines) of oil when the level is at
the bottom of the SAFE range will
result in the level being at the top of
the SAFE range.
• 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.
Engine Oil Filter Replacement
The engine oil filter should be
replaced with a new filter at every oil
change.

Dealer to perform this service.

Wiper Maintenance and Blades
Replacement Windshield Wiper Arms Lifting
When the windshield wiper arms are
in rest position it is not possible to
check or replace the blades as they
remain under the engine hood.
To service the blades it is necessary to
move the wiper arms in “Service”
position (see chapter “Wipers and
Washers” in section “Understanding
the Vehicle”). In this way it is possible
to lift the arms for cleaning or
replacing the wiper blades.
WARNING!
It is dangerous to operate or service
the wiper blades with the windshield
wipers in an active position (any
position different from “OFF”) and
with the ignition switch in the RUN
position. The rain sensors may
suddenly activate the wipers. Always use the “Service” position for any
intervention on the windshield wiper
blades.
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 on the glass,
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/rear
window glasses 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.
Always use washer fluid when using
the wipers to remove salt or dirt from
a dry windshield.
Avoid using the wiper blades to
remove frost or ice from the
windshield. Keep the blade rubber out
of contact with petroleum products
such as engine oil, gasoline, etc.
Spray nozzles If the jet does not work, first check
that there is fluid in the tank (see
paragraph “Level checks” in this
section) then check that the nozzles
are not clogged.
Windshield Wiper Blades Replacement
• Move the wiper arms into “Service”
position, (see chapter “Windshield
Wipers and Washers” in section
“Understanding the Vehicle”) and lift
them.
• Press the indicated button, slip off
the blade support from the arm and
replace it.
• Return the blade to its original
position on the windshield.
• Turn the multifunction lever to one
of the automatic settings (see
chapter “Windshield Wipers and
Washers” in section “Understanding
the Vehicle”) and move the ignitionMaintenance and Care

water for too long directly on the
module.
