CAUTION!
• To jump start a vehicle do not use a
portable battery, a booster pack or
any other booster source with a
system voltage greater than 14 Volts
or damage to the battery, starter
motor, alternator or electrical system
of the vehicle with the discharged
battery may occur.
• Do not use a battery charger for
emergency starting under any
circumstances. You could damage
the electronic systems, particularly
the control units managing the
ignition and fuel supply functions.
• If the battery is completely
discharged when the windows are
fully raised, open the door with the
utmost care; do not close the door
again until it is possible to lower the
window.
WARNING!
Always secure your vehicle by fully
applying the parking brake, before
activating the manual park release.
Activating the manual park release
could allow your vehicle to roll away if it is not secured by the parking
brake. Activating the manual park
release on an unsecured vehicle could
lead to serious injury or death for
those in or around the vehicle.
NOTE:
If
you need
to disconnect the battery
from the vehicle electrical system, see
“Maintenance — Free Battery” in
section “Maintenance and Care”).
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 known 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
information go to: www.P65Warnings.ca.gov/passenger-
vehicle
Battery Remote Posts Position For easier operation, remote battery
posts for jumpstarting are located in
the engine compartment while the
battery is stored in the trunk.
Open the engine hood (see “Hood
Operation” in section “Before
Starting”) the positive remote post (+)
and the negative remote post (-) are
easily recognizable by the icons
labeled on the integrated power
module.In an Emergency

• short, repeated journeys (less than
4–5 mi/7-8 km) at sub-zero outside
temperatures;
• engine often idling or driving long
distances at low speeds or long
periods of idleness;
you should perform the following
inspections more frequently than
recommended on the “Scheduled
Service Plan”:
• check front disc brake pad conditions
and wear;
• check cleanliness of hood and trunk
locks, cleanliness and lubrication of
linkage;
• visually inspect conditions of: engine,
transmission, pipes and hoses
(exhaust - fuel system - brakes) and
rubber elements (boots - sleeves -
bushes - etc.);
• check battery charge;
• visually inspect condition of the
accessory drive belts;
• check and, if necessary, change
engine oil and replace oil filter;
• check and, if necessary, replace
pollen filter of the A/C system;
• check and, if necessary, replace air
cleaner filter. CAUTION!
All maintenance operations for the
vehicle must be carried out by an
Authorized Maserati Dealer . For
routine and minor maintenance
operations which you can carry out
yourself, make sure that you have the
necessary experience and always use
suitable equipment, original Maserati
spare parts and the prescribed fluids.
Shall this not be the case, do not carry
any operation on your own and
contact an Authorized Maserati
Dealer .
On Board Diagnostic System Your vehicle is equipped with a
sophisticated on board diagnostic
system called OBD II. This system
monitors the performance of the
emissions, engine, and automatic
transmission control systems. When
these systems are operating properly,
your vehicle will provide excellent
performance and fuel economy, as
well as engine emissions suited to
current government regulations.
If any of these systems require service,
the OBD II system will turn on the
Malfunction Indicator Light
on the
instrument cluster display (refer to “Instrument Cluster” in section
“Dashboard Instruments and
Controls”). The system stores as well
diagnostic codes and other
information to assist your service
technician by performing repairs.
Although the vehicle will be driveable
and will not need towing, contact an
Authorized Maserati Dealer for service
as soon as possible.
CAUTION!
• Prolonged driving with the MIL
on could cause further damage to
the emissions control system. It could
also affect fuel economy and
driveability. The vehicle must be
serviced before any emissions tests
can be performed.
• If the MIL
is flashing while the
engine is running, severe catalytic
converter damage and power loss
will soon occur. Immediate service at
an Authorized Maserati Dealer is
required.
Emissions Inspection and
Maintenance Programs In some localities, it may be a legal
requirement to pass an inspection of
your vehicle's emissions control system.Maintenance and Care
