A/C System Maintenance For the best performance, the air
conditioning system should be
checked and serviced by an
Authorized Maserati Dealer at the
beginning of the warm season.
This service should include cleaning of
the condenser, check of the drive belt
tension and a performance test.
During the winter, the air conditioning
system should be operated at least
once a month for about 10 minutes.
CAUTION!
Do not use chemical flushes in your air
conditioning system as the chemicals
can damage your air conditioning
components. Such damage is not
covered by the New Vehicle Limited
Warranty.
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:
www.P65Warnings.ca.gov/passenger-
vehicle
WARNING!
• Use only refrigerants and
compressor lubricants approved by
the manufacturer for your air
conditioning system. Some
unapproved 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 Authorized Maserati Dealer.
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 “Hood Operation” in
section “Before Starting”.Maintenance and Care

“Driving”). The thinner is the tread,
the greater is the risk of skidding.
• Drive carefully on wet roads to
decrease the risk of aquaplaning.
Winter Tires
These tires are specially
designed for
driving on snow and ice and are fitted
to replace the ones supplied with the
vehicle.
The specific features of the winter
tires lead to lower performance under
normal environmental conditions or
on long highway trips, compared to
the standard tires.
Therefore, their use should be limited
to the situations and performance for
which they have been type-approved.
The Authorized Maserati Dealer can
provide all necessary information
about fitting winter tires on the
vehicle.
NOTE:
• We recommend fitting winter tires
on the vehicle at temperatures
below 45 °F (7°C) since the driving
performance of summer tires is
reduced at low temperatures.
Summer tires may be permanently
damaged at extremely low
temperatures.
• Comply with all state and local laws governing snow tire and tread depth
requirements.
Wheel Rims Maintenance All wheel trims should be cleaned
regularly with a mild soap and water.
To remove heavy soil and/or excessive
brake dust, use a nonabrasive,
non-acidic cleaner.
Do not use scouring pads, steel wool,
a bristle brush, or metal polishes.
Do not use oven cleaner that may
affect and damage the brake calipers.
Avoid automatic car washes that use
acidic solutions or harsh brushes that
may damage the wheel rim protective
finish.Bodywork Maintenance
and Care Protection from Atmospheric
Agents The main causes of corrosion are:
• atmospheric pollution;
• salinity and humidity in the
atmosphere (marine areas or a damp
climate);
• seasonal environmental conditions;
• salt scattered on the roadbed to
melt ice and snow.
The abrasive action of wind-carried
atmospheric dust and sand, mud and
stones should not be underestimated.
On this vehicle, Maserati has adopted
the best technological solutions to
protect the bodywork from corrosion.
The main measures are:
• paint products and systems that give
the vehicle particular resistance to
corrosion and abrasion;
• use of galvanized (or pre-treated)
metal sheets which are highly
resistant to corrosion in the most
exposed parts;
• spraying of the underbody, engine
compartment, insides of wheel
housings, and other structures withMaintenance and Care
7
397

wax products having high protective
power;
• spraying of plastic materials, with a
protective function, in the most
exposed points: underneath the
doors, inside part of the mud guards,
edges, etc.;
• use of ventilated box sections, coated
with protective wax products, to
avoid condensation and trapped
water which could encourage the
formation of internal rust.
Useful Advice to Keep the
Bodywork in Good Condition Paint
The paintwork does not only have an
aesthetic function but also protects the
underlying metal sheets. In the event
of abrasions or deep scratches, we
recommend to have the necessary
touch-ups made immediately, to avoid
any rust formation. Touch-ups do not
feature particular difficulties, even on
metallic finishes.
For all paint touch-ups, use only
original products indicated on the
plate applied on the lower left side of
the hood. Normal paint maintenance consists in
washing, the frequency of which
depends on the conditions of use and
of the environment. For example, if
driving the vehicle in areas where
there is high atmospheric pollution or
the roads are spread with anti-freeze
salt, it is advisable to wash the vehicle
more frequently.
ENVIRONMENTAL!
Detergents pollute water. Therefore
the vehicle should be washed in areas
equipped for the collection and
purification of the fluids used for
washing. NOTE:
The use of alcohol-based products for
cleaning the metal surfaces in the
engine compartment and/or the trunk
may deteriorate the protective paint. It
is recommended to use water-based
products.
Car Wash
For correct washing:
• wet the bodywork with a low
pressure water jet;
• pass a sponge with a light detergent
solution over the bodywork,
frequently rinsing the sponge;
• rinse well with water and dry with an
air jet or chamois leather.
When drying, take particular care with
the parts that are less visible, such as
the door, liftgate and lid bays,
headlight edges, in which water can
be trapped more easily.
You are recommended not to take the
vehicle immediately into an enclosed
environment, but leave it in the open
air so as to allow the water to
evaporate.
Do not wash the vehicle after it has
been left in the sun or when the hood
is hot: the paint gloss could be
affected.Maintenance and Care
7

any other equipment such as
brushes, steel wool, abrasives or any
other equipment for cleaning.
• After cleaning, please rinse the
aluminum trim with a lot of clear
water.
• While cleaning in the car, please
make sure that the moldings and
aluminum trims only get in contact
with soft brushes or textiles.
Engine Compartment
At the end of each winter season,
carefully wash the engine
compartment, remembering to avoid
directing the jet of water for too long
on the electric parts.
To perform this operation, you must
contact an Authorized Maserati
Dealer .
Pre-Short Drop Function When in a car wash, if the driver keeps
the RKE Transmitter in his/her pocket,
or in any place outside the vehicle
within 3.3 ft (1 m) distance, the front
windows will perform a pre-short
drop. This is a shorter drop compared
to the normal short drop performed by
the “Passive Entry” function when you
grab the door handle to enter the
vehicle. In order to prevent water from
entering the vehicle between the
upper edge of the glass window and
the door outline on the bodywork,
while the car is being washed, it is
advisable to disable the “Passive
Entry” from the MTC+ System, for
further information refer to chapter
“MTC+ Settings” in section
“Dashboard Instruments and controls”.
When deactivating the “Passive Entry”,
also the “Pre-Short Drop” function will
be disabled.
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 solventsMaintenance and Care

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 damp cloth.
