Maintenance and Care

NOTE:
•We recommend fitting winter tires
on the vehicle at temperatures 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 withwax 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 inside the hood.

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'stransparent 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 anAuthorized
Maserati Dealerwhich has the
required specific products.
Parts in Premium Quality Wood
Remove any dirt with a buckskin
leather or damp cloth.
NOTE:
TheAuthorized Maserati Dealercan
provide you with any information
about the Maserati approved “Car
Care” products, available in the
“Genuine Accessories” range.
WARNING!
California Proposition 65

a passenger vehicle or off-road vehicle
can expose you to chemicals including
such as, engine exhaust, carbonmonoxide, 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

Vehicle Stored for Long
Periods
If the vehicle is going to be stored for
over a month, follow the below
precautions:
• Wash and dry the vehicle
thoroughly.
• Store the vehicle in a covered, dry
and, if possible, ventilated area.
• Select P (Park) and turn off the
engine.
• Turn the key in the ignition switch in
STOP (OFF)position.
• Disconnect the battery (refer
“Maintenance-Free Battery” in this
section) or connect a battery charger
(refer to paragraph “Maintaining
Battery Charge” of chapter “Battery
Statement” in this section).
• Check the battery charge status.
During parking, this check must be
carried out every three weeks.
Recharge the battery if the open
circuit voltage is lower than 12.2 V.
• Check that the parking brake is NOT
engaged.
• Do not empty the engine cooling
system.
• Clean and protect the painted parts
applying protective wax.• Clean and protect polished metal
parts with special products available
on the market.
• Talc the windshield wiper blades and
raise them from the windshield.
• Cover the vehicle with a long cloth
in breathable fabric (available from
theAuthorized Maserati Dealer). Do
not use thick plastic sheets, which do
not allow the humidity on the
vehicle surface to evaporate.
• Inflate the tires up to a pressure
which must be 1 bar (14.5 psi) higher
than the normally prescribed one,
and check it at regular intervals.
NOTE:
TheAuthorized Maserati Dealercan
provide you with any information
about the available “Indoor and
Outdoor Car Covers”, available in the
“Genuine Accessories” range.
WARNING!
The tire pressure must be brought
back to the prescribed value before
reusing the vehicle (see “Tire Inflation
Pressure” in section “Features and
Specifications”).
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.
