Materials Added to Fuel
All gasoline sold in the United States is
required to contain effective
detergent additives. Use of additional
detergents or other additives is not
needed under normal conditions and
they would result in additional cost.
Therefore, you should not have to add
anything to the fuel.
Fuel System Warnings
WARNING!
Follow these guidelines to maintain
your vehicle's performance:
•
The use of leaded gasoline is
prohibited by Federal and Provincial
law. Using leaded gasoline can impair
engine performance and damage the
emissions control system.
• The use of fuel additives, which are
now being sold as octane enhancers,
is not recommended. Most of these
products contain high
concentrations of methanol. Fuel
system damage or vehicle
performance problems resulting
from the use of such fuels or
additives is not the responsibility of
Maserati. NOTE:
Intentional

tampering with the
emissions control system can result in
civil penalties civil penalties and could
void the vehicle warranty.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust
gases is deadly. Follow the
precautions below to prevent carbon
monoxide poisoning:
• Do not inhale exhaust gases. They
contain carbon monoxide, a
colorless and odorless gas, which
can kill. Never run the engine in a
closed area, such as a garage, and
never sit in a parked vehicle with
the engine running for an extended
period. If the vehicle is stopped in
an open area with the engine
running for more than a short
period, adjust the ventilation system
to force fresh, outside air into the

set of jumper cables and a battery of
another vehicle or by using a portable
battery booster. It is necessary to have
proper jumper cables in order to
connect the booster battery to the
remote posts of the discharged
battery. Booster cables have usually
positive and negative terminal clamps
and are identified by a different
sheath color (red = positive, black =
negative). Maserati provides on
request jumper cables created for its
models and content in a practical case.
NOTE:
The Authorized Maserati Dealer can
provide you with information about
the “Maserati Jumper Cables Kit”,
available in the “Genuine Accessories”
range.

done improperly so please follow the
procedures in this section carefully. NOTE:
When using a portable battery
booster pack, follow the battery
manufacturer’s operating instructions
and precautions.
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.
