If the vehicle is stored for
long periods
If the vehicle is not used for
several months, take the following
precautions:
- Wash and dry the vehicle
thoroughly.
- Store the vehicle in a covered, dry
and, if possible, ventilated area.
- Select P (PARK), then turn the key
to position STOP (OFF) .
- Disconnect the battery (see
page 193).
- Check the battery charge condition.
This check should be performed
every three weeks while the vehicle
is stored. Recharge the battery if
the load-free voltage is below
12.5 V.
- Check that the electric parking
brake is not applied.
- Clean and protect the painted parts
applying protective waxes.
- Clean and protect polished metal
parts with specific products
available on the market.
- Talc the windshield wiper
blades and raise them from the
windshield.
- Cover the vehicle with a long cloth
in transpirating fabric (available at
your 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 7.25 psi (0.5 bar)
higher than the normally prescribed
one, and check it at regular
intervals.
The tire pressure must
be brought back to the
prescribed value before
reusing the vehicle.
- Do not drain the engine cooling
system.
Battery charge status
To avoid problems with ignition and/
or the electrical system in general
when you are driving, the battery
charge status is constantly maintained
and guaranteed by the vehicle’s
recharge circuit; the main component
of which is the alternator. This circuit
is only able to supply voltage to the
battery when the vehicle is traveling.
The warning light
(see page 66),
located on the instrument panel,
will indicate any malfunctions in
the recharge circuit (solid light) or
an insufficient battery charge status
(flashing).
The amount of voltage that is
supplied to the battery to maintain
the charge status also depends on
the amount of charge absorbed by
the systems used in the vehicle, for
example: the air conditioning system,
the lights, windshield wipers, the
audio system etc. In addition to this,
even the traffic conditions you are
driving in can influence the amount
of charge produced: if, for example,
you are traveling on the highway,
the alternator supplies more voltage
to the battery, while in heavy traffic,
where the vehicle is continually
stopping and starting, the alternator
provides less charge. This also applies
for the amount of electrical charge
stored in the battery to power other
electrical devices while the vehicle is
traveling.
The vehicle is fitted with advanced
electronic systems, such as, for
example, the anti-theft system and
various electronic control modules,
which consume power even when
the ignition switch is in the
STOP
position and the vehicle is not being
used. Therefore, it is fundamental
that the battery is properly charged to
ensure that the engine starts properly
and that all the electrical/electronic
systems in the vehicle work efficiently.
