surface, use the paint care products
recommended and approved by Mercedes-
Benz.T his is the case approximately every
three to five months, depending on the
climate conditions and the care product used.
If the dirt has penetrated the paint surface or
if the paintwork has become dull, then the
paintwork should be cleaned. For cleaning,
please use the paint cleaner recommend and
approved by Mercedes Benz.
Do not use these care products in the sun or
on the hood while the hood is hot.
Matte finish care !
Never polish the vehicle or the light alloy
wheels. Polishing causes the finish to
shine.
! The following may cause the paint to
become shiny and thus reduce the matte
effect:
R Vigorous rubbing with unsuitable
materials.
R Frequent use of car washes.
R Washing the vehicle in direct sunlight.
! Never use paint cleaner, buffing or
polishing products, or gloss preserver, e.g.
wax. These products are only suitable for
high-gloss surfaces. Their use on vehicles
with matte finish leads to considerable
surface damage (shiny, spotted areas).
Always have paintwork repairs carried out
at a qualified specialist workshop.
! Do not use wash programs with a hot wax
treatment under any circumstances.
Observe these notes if your vehicle has a
clear matte finish. This will help you to avoid
damage to the paintwork due to incorrect
treatment. Care
