with the ignition system and other
electrical/electronic systems.
The Authorized Maserati Dealer is
available to advise you on how to
recharge you battery correctly and
give you useful information on battery
care and maintenance.
NOTE:
The Authorized Maserati Dealer can
provide you with any information
about the Maserati approved "Battery
Charger and Conditioner", available in
the Genuine Accessories range.
WARNING!
The process of charging or recharging
the battery produces hydrogen, a
dangerous gas that can explode and
cause serious injuries. When charging
or recharging the battery, follow the
recommended precautions at all times:
7
• always charge or recharge the
battery in a well-ventilated
environment;
• never charge or recharge a battery
that has frozen: it can explode due
to hydrogen trapped inside the ice
crystals;
286
• ensure that any sparks or open
flames are kept well away from the
battery while it is charging;
• before using a charger to charge or
maintain the battery charge status,
carefully follow the instructions
provided to ensure the charger is
connected to the battery safely and
correctly.
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. You can
consult the paragraph "Battery
Reconnection" in this chapter for
further information on this subject.
• With the transmission in N (Neutral),
let the engine idle for several
minutes.
WARNING!
The engine idle must be performed
outdoors. Exhaust gases contain
carbon monoxide which is strongly
toxic and potentially lethal.
