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.
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
Maintenance and Care

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
WARNING!
•Use only refrigerants and
compressor lubricants approved by
the manufacturer for your air
conditioning system. Some
refrigerants are flammable and can
explode, causing injuries. Other
unapproved refrigerants or
lubricants can cause the system to
fail, requiring costly repairs.
•The air conditioning system contains
refrigerant under high pressure. To
avoid risk of personal injury or
damage to the system, adding
refrigerant or any repair requiring
lines to be disconnected should be
done by an experienced technician.
Periodically remove any leaves and
insects that may build up and obstruct
the inlet of external air in the air
conditioning system through the grille
present underneath the rear part of
the hood.
To access the grille, lift the hood as
described in “Open and Close the
Hood” in section “Before Starting”.
A/C Air Filter Replacement
This filter performs mechanic/
electrostatic air filtering, provided
that windows and doors are perfectly
closed.
Have your filter replaced at least once
a year at anAuthorized Maserati
Dealer, preferably at the beginning of
the summer period.
If the vehicle is mainly used in the city
traffic, on highways or dusty roads, we
recommend that you replace the
filters more frequently than prescribed
in the "Scheduled Service Plan" of this
section.
CAUTION!
Failure to replace the filter may
considerably reduce the air
conditioning and heating system
efficiency.
