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”).
Maintenance and Care

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 section “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.

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 vehiclethoroughly.
• 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
the Authorized 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:
The Authorized Maserati Dealer can
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.

• The tire inflation pressure value are
also indicated on the driver's side at
the base of the rear door pillar.
WARNING!
• Improperly inflated tires are
dangerous and can cause collisions.
• Under-inflation increases tire flexing
and can result in tire overheating
and failure.
• Over-inflation reduces a tire's ability
to cushion shock. Objects on the
road and potholes can cause damage
that result in tire failure.
• Over-inflated or under-inflated tires can affect vehicle handling and can
fail suddenly, resulting in loss of
vehicle control.
• Unequal tire pressures can cause
steering problems. You could lose
control of your vehicle.
• Unequal tire pressures from one side
of the vehicle to the other can cause
the vehicle to drift to the right or
left.
• Always drive with each tire inflated
to the recommended cold tire
inflation pressure.
