WARNING!
California Proposition 65
Operating, servicing and maintaining
a passenger vehicle or off-road vehicle
can expose you to chemicals including
such as, engine exhaust, carbon
monoxide, phthalates and lead, that
which are know to the State of
California to cause cancer and birth
defects or other reproductive harm. To
minimize exposure, avoid breathing
exhaust, do not idle the engine except
as necessary, service your vehicle in a
well-ventilated area and wear gloves
or wash your hands frequently when
servicing your vehicle. For more

Useful Advice to Extend
Battery Life
When parking the vehicle, make sure
that the doors, front, rear lids and
flaps are properly closed. All interior
lights should be off.
When the engine is turned off, do not
keep the connected devices switched
on for a long time (such as radio,
hazard warning flashers, fan, etc.).
CAUTION!
If the battery charge remains below
50% for a long period of time, it will
be damaged due to sulfation; its
performance and starting power will
be reduced and it will be more subject
to freezing (this can happen even at
14°F/-10°C).
We recommend you to have the
battery charge condition checked,
preferably at the beginning of the
cold season, to prevent the electrolyte
from freezing.
This check should be carried out more
frequently if the vehicle is used mainly
for short trips or if it is equipped with
power absorbing devices that remain
permanently on even when the
ignition switch is off. This appliesabove all if these devices have been
retrofitted ("Aftermarket" services).
If the vehicle is not used for long
periods of time, please see “Vehicle
Stored for Long Periods” in this
section.
Battery Recharge
WARNING!
The process of charging or recharging
the battery produces hydrogen, a
flammable gas that can explode and
cause serious injuries. When charging
or recharging the battery, follow the
recommended precautions at all
times.
•Before using a charger device
always check that this tool is
suitable for the installed battery,
with constant voltage (lower than
14.8 V) and low amperage
(maximum limit 15 A).
•Recharge the battery in a
well-ventilated environment.
•Never charge or recharge a frozen
battery: it can explode due to
hydrogen trapped inside the ice
crystals.
•Ensure that any sparks or open

Fuse Replacement
Used Fuses Characteristics
When an electrical device is not
functioning, check that the
corresponding fuse is in proper
working order (intact).
AFuse intact
BFuse blown
Replace the faulty fuse with a new
one featuring the same rating, by
using appropriate forceps.The color identifies the value of the
fuses in amperes which is also
reported on them.
The vehicle is endowed with mini- and
maxi-fuses.
The table shows the match between
color and amperage of mini and maxi
fuses.

CAUTION!
• Never replace a blown fuse with
anything other than a new and
suitable fuse (same rating).
• After replacing a fuse, if the fault
recurs, contact anAuthorized
Maserati Dealer.
Position of Fuses
The fuses are located in three parts of
the vehicle, namely:
• On the right hand side of the engine
compartment.
• Behind the glove compartment, to
the left of the steering wheel.
• In the trunk compartment next to
the battery.

• Refit the domelight inserting first the
electrical connector side and then
pressing the other side until it is
firmly secured in place.
Courtesy Mirror Light
To replace the bulb (12V - 5W
“torpedo” type):
• Remove the fixing frame from the
sun visor by levering it out gently at
points indicated in picture.
• Replace the bulb located on the back
of the mirror frame.
• Refit the fixing frame by pressing it
on the sun visor.
Trunk Compartment Light
To replace the bulb (W5W) inside the
trunk compartment, proceed as
follows after trunk lid opening.• Remove the light fixing frame by
levering it out gently at the indicated
point with a screwdriver.
• Raise the lens cover.
• Replace the pressure-fitted bulb.
• Refit the lens cover, inserting first the
electrical connector side and then
pressing on the other side.
A/C System Maintenance
For the best performance, the air
conditioning system should be checked
and serviced by anAuthorized
Maserati Dealerat the beginning of
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.

vehicleVehicle Stored for Long
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.WARNING!
The engine idle must be performed
outdoors. Exhaust gases contain
carbon monoxide which is strongly
toxic and potentially lethal.

Battery Statement
Battery Statement Status of
Charge
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 on the
instrument cluster (see “Instrument
Cluster” in section “Dashboard
Instruments and Controls”), will
indicate any malfunctions in the
recharge circuit or an insufficient
battery charge status (flashing).
The vehicle is fitted with advanced
electronic systems, such as, for
example, the alarm system and various
electronic control modules, which
consume power even when the key in
the ignition switch is in theSTOP (OFF)
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
