XUseasuitablet ouch-up stick, e.g. MB Touch-
Up Stick,tor epair slight damage to the paint-
work quickly and provisionally.
Mattef inish 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:
Rstrong rubbing of the paintwork with
unsuitablem aterials
Rfrequent use of automatic car washes
Rwashing the vehicle in direct sunlight
!Never use paint cleaner, buffing or polishing
products, or gloss preserver, e.g. wax, for the
purpose of paintwork care. These products
are only suitablef or high-gloss surfaces. Their
use on vehicles with matte paintwork leads to considerable surface damage or, more spe-
cifically,tos hiny, spotted areas.
Alwaysh ave paintwork repairs carried out at a
qualified specialist workshop.
!Do not use wash programs with ahot wax
treatment under any circumstances.
Observe these notes if your vehicle has aclear
matte finish. This will help you to avoid damage to the paintwork due to incorrect treatment.
These notes also apply to light alloy wheels with
ac lear matte finish.
