Air conditioning system
During the winter, the air conditioning
system should be operated at least
once a month for about 10 minutes.
Before the summer season, have the
system checked by your local
Authorized Maserati Dealer.
WARNING: The system uses R134a type
coolant that, in the event of accidental
leakage, is not harmful for the
environment. Under no circumstances
should you use R12 coolant that, in
addition to being incompatible with
the system components, contains
chloroflurocarbons (CFCs).
Bodywork
Protection from atmospheric
agents
The main causes of corrosion are:
– atmospheric pollution
– salt and humidity in the atmosphere
(marine areas or a damp climate)
– seasonal environmental conditions.
– salt used to remove snow/ice from
roads.
The abrasive action of wind-carried
atmospheric dust and sand, mud and
stones should not be underestimated.
On your vehicle, MASERATI has
adopted technological solutions to
help protect the bodywork from
corrosion.
The main measures are:
– Paint products and systems that give
the vehicle particular resistance to
corrosion and abrasion.
– Use of galvanized (or pre-treated)
sheet metal which is highly resistant
to corrosion in the most exposed
parts.
– Spraying of the underbody, engine
compartment, insides of wheel
housings, and other structures with
wax products having high protective
power.
– Spraying of plastic materials, with a
protective function, in the most
exposed points: underneath the
doors, inside part of the fenders,
edges, etc.
– Use of ventilated box sections,
coated with protective wax
products, to avoid condensation and
trapped water which could
encourage the formation of internal
rust.
Advice for keeping the
bodywork in good condition
Paint
The paintwork does not only have an
aesthetic function but also serves to
help protect the sheet metal. In the
event of abrasions or deep scratches,
we recommend to have the necessary
touch-ups made immediately, to avoid
any rust formation.
Touch-ups do not feature particular
difficulties, even on metallic finishes.
For all paint touch-ups, use only
original products indicated on the
label applied on the engine
compartment lid.
