Maintenance and Care

Normal paint maintenance consists in
washing, the frequency of which
depends on the conditions of use and
of the environment. For example, if
driving the vehicle in areas where
there is high atmospheric pollution or
the roads are spread with anti-freeze
salt, it is advisable to wash the vehicle
more frequently.
ENVIRONMENTAL!
Detergents pollute water. Therefore
the vehicle should be washed in areas
equipped for the collection and
purification of the fluids used for
washing.NOTE:
The use of alcohol-based products for
cleaning the metal plates in the engine
compartment and/or the trunk may
deteriorate the painted surface. It is
recommended to use water-based
products and neutral surfactants.
Car Wash
For correct washing:
• wet the bodywork with a low
pressure water jet;
• pass a sponge with a light detergent
solution over the bodywork,
frequently rinsing the sponge;
• rinse well with water and dry with an
air jet or chamois leather.
When drying, take particular care with
the parts that are less visible, such as
the door and lid bays, headlight edges,
in which water can be trapped more
easily.
You are recommended not to take the
vehicle immediately into an enclosed
environment, but leave it in the open
air so as to allow the water to
evaporate.
Do not wash the vehicle after it has
been left in the sun or when the hood
is hot: the paint gloss could be
affected.External plastic parts must be cleaned
with the same procedure followed for
the normal washing of the bodywork.
Avoid, as far as possible, parking the
vehicle under trees; the resinous
substances that very often drop from
the trees give the paint a dull
appearance and increase the possibility
of originating corrosive processes.
It is important that the drain holes in
the lower sides of the doors, rocker
panels, and trunk bottom be kept clear
and open.
CAUTION!
• Bird droppings must be washed off
immediately and thoroughly, since
their acidity is particularly corrosive.
• To provide better protection for the
paint, polish the vehicle at intervals
with a suitable product leaving a
protective film on the paint.
• If the vehicle is washed using
high-pressure water jets or cleaners,
it is important that the nozzle of the
jet be kept at a distance of at least
16 in (40 cm) from the bodywork to
avoid damaging it.
• If you are washing the vehicle with
roller brushes, you must protect the
edges of the rear, lateral brand

miles/6000 km. Please note that
allowing the battery to go dead
repeatedly can cause premature wear
on the internal cells and greatly
reduce their life, leading to problems
with the ignition system and other
electrical/electronic systems.

recommended precautions at all
times:
•always charge or recharge the
battery in a well-ventilated
environment;•never charge or recharge a battery
that has frozen: it can explode due
to hydrogen trapped inside the ice
crystals;
•ensure that any sparks or open
flames are nowhere near the battery
while it is charging;
•before using a charger to charge or
maintain the battery charge status,
carefully follow the instructions
provided to ensure the charger is
