Maintenance and Care
• 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.
Useful Advice to Keep the
Bodywork in Good Condition
Paint
The paintwork does not only have an
aesthetic function but also protects
the underlying 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
function particular difficulties, even on
metallic and matte finishes.
For all paint touch-ups, use only
original products indicated on the
plate applied on the lower left side of
the hood.

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 boot
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
