2019 MASERATI GRANTURISMO CONVERTIBLE maintenance schedule

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.
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

o assure proper lubrication of your
vehicle's engine, the engine oil must
be maintained at the correct level. If

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 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, other
than leak detection dyes. Engine oil
is an engineered product, and its
performance may be impaired by
supplemental additives.

• Start the vehicle and warm it up until the
temperature stabilizes.
• Turn off the engine, remove the filler neck cap and wait 5 minutes to allow
the oil to flow into the oil pan. • Remove the dipstick and clean it with
a dry and clean cloth.
• 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, adding 0.4 US gallons (1,5 liters ) 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.
Maintenance and Care

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.

Wheels Maintenance
Tires Maintenance
CAUTION!
To obtain the best performances and
the longest mileage from the tires,
take the following precautions during
the first 310 mi (500 km):
• do not drive at the vehicle’s maximum speed;
• drive at low speed on curves;
• avoid sudden steering;
• avoid sudden braking;
• avoid sudden acceleration;
• do not drive at high speeds for too long.
The tires inflation pressure must
correspond
to the prescribed values
(see the chapter “Tire Inflation
Pressure” in section “Features and
Specifications”) and should be
checked only when the tires have
cooled down. In fact, the pressure
increases as the tire temperature
progressively increases.
Never reduce the pressure if tires are
hot (see “Tires – General Information”
chapter in section “Driving”).

Interior Maintenance and
Care
Interior trim should be cleaned
starting with a damp cloth. Do not use
harsh cleaners.
The leather upholstery can be best
preserved by regular cleaning with a
damp soft cloth. Small particles of dirt
can act as an abrasive and damage the
leather upholstery and should be
removed promptly with a damp cloth.
Stubborn soils stains can be removed
easily with a soft cloth and
appropriate products. Avoid soaking
the leather upholstery with any liquid.
Please do not use polishes, oils,
cleaning fluids, solvents, detergents, or
ammonia-based cleaners to clean your
leather upholstery.
Application of a leather conditioner is
not required to maintain the original
condition.
Check at regular intervals that there is
no water trapped under the mats (due
to drips off shoes, umbrellas etc.)
which may cause the metal parts to
oxidize.
CAUTION!
Do not use alcohol, petrol or solvents
to clean the instrument cluster's transparent dome, the MTC+ display,
the analog clock and the leather
upholstery. We recommended the use
of “Car Care” products approved by
Maserati for the maintenance and care
of the interior.
Leather Upholstery Treatment
Have the leather upholstery only
treated, as provided in the Scheduled
Service Plan, by an
Authorized
Maserati Dealer which has the
required specific products.
Parts in Premium Quality Wood
Remove any dirt with a buckskin
leather or damp cloth.
NOTE:
The Authorized Maserati Dealer can
provide you with any information
about the Maserati approved “Car
Care” products, available in the
“Genuine Accessories” range.
