Car eand treatment of matt paintwo rkIf
your vehicle has aclear mat tfinish, observe
the followin ginstructions in order to avoid
damage to the paintwork due to incorrect
care.
These notes also appl ytolight alloy wheels
with aclear mat tfinish.
! Neve rpolish the vehicle or the light alloy
wheels. Polishing makes the paintwork
shiny. !
The following ma ycause the paint to
become shiny and thus reduce the matt
effect:
R Vigorous rubbing with unsuitable mate-
rials.
R Frequent use of car washes.
R Washing the vehicle in direct sunlight.
! Never use paint cleaner, buffing or pol-
ishing products, or glos spreserver, e.g.
wax .These product sare onl ysuitable for
high-glos ssurfaces. Thei ruse on vehicles
wit hm att finish leads to considerable sur-
face damage (shiny, spotted areas).
Always have paintwork repairs performed
at aq ualified specialist workshop, e.g. a
Mercedes-Benz Servic eCentre.
! Do not use wash programs with ahot wax
treatment under any circumstances.
