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 efficiency checked by the
Maserati Service Network.
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 fluid that, in
addition to being incompatible with
the system components, contains
chloro-fluoro-carbons (CFCs).

Bodywork

Protection from atmospheric
agents
The main causes of corrosion are:
– atmospheric pollution
– salinity and humidity in the
atmosphere (marine areas or a damp
climate)
– seasonal environmental conditions.
– salt scattered on the roadbed to melt
ice and snow.
The abrasive action of wind-carried
atmospheric dust and sand, mud and
stones should not be underestimated.
On your vehicle, MASERATI has
adopted the best technological
solutions to 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 galvanised (or pre-treated)
metal sheets which are 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 mud guards,
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.
Advices for keeping the
bodywork in good condition
Paint
The paintwork does not only have an
aesthetic function but also serves to
protect the metal sheets. 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
plate applied on the engine
compartment lid.
