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.

Tire Inflation Pressure
Tire Pressure
Front and rear 220 kPa - 2,2 bar
-32psi
Spare wheel
(optional)350 kPa - 3,5 bar
-51psi
NOTE:
•For more information about the
pressure check methods, see “Tires –
General Information” in section
“Driving”.
•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 tirescan 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.
