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!

WARNING!
• Use only refrigerants and
compressor lubricants approved by
the manufacturer for your air
conditioning system. Some
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 experienced technician. 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 an Authorized 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. WARNING!

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”). Insufficient tire inflating pressure can
cause tire overheating and possible
internal damage, which may even lead
to the tire destruction.
CAUTION!
After inspecting or adjusting the tire
pressure, always reinstall the valve
stem cap. This will prevent moisture
and dirt from entering the valve stem,
which could damage it.
Impacts with curbs, holes, and
obstacles
in the road, and prolonged
trips on rough roads can cause tire
damage which may not be visible to
the naked eye.
Check your tires regularly for any signs
of damage (e.g. scratches, cuts, cracks,
bulges, etc.). If sharp objects penetrate
the tires, they can cause structural
damage which is only visible when the
tire is removed.
In any case, any possible damage must
be inspected by an experienced tire
fitter, as it may seriously reduce the
tire life.
Remember that tires deteriorate with
time, even if used little or not at all.
Cracks in the tire tread and sides,
alongside possible bulging, are a sign
of deterioration. WARNING!
• Check the inflating pressure of the
tires when cold, at least every two
weeks and before long trips.
• Have the old tires inspected by an
experienced technician, to make sure
they can still be used safely. If the
same tire has been on your vehicle
for 4 or 5 years, have it inspected
anyway by an experienced
technician.
• Never fit tires of uncertain origin.
• “Directional” tires have an arrow on
their side showing the rolling
direction. To keep the best
performance when replacing a tire,
make sure that the rolling direction
corresponds to the one shown by
the arrow.
• During the tire life, the rolling
direction used for the first fitting
shall always be observed, also in
case of “nondirectional” tires.
• Check the depth of the tire tread at
regular intervals. The minimum
allowed value is 0.06 in (1,6 mm) at
that point the wear indicators on the
tire will be visible (see “Tires –
General Information” in sectionMaintenance and Care
7
254

“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 features of these tires are
significantly reduced in winter when
tread depth is less than 0.157 in (4
mm). In this case, they should be
replaced.
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 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
255

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 inside 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 plates in the engine
compartment and/or the trunk may
deteriorate the painted surface. It is
recommended to use water-based
products and neutral surfactants.
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 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
