Up Stick ,tor epair slight damage to the paint-
work quickly and provisionally.
Matt ef 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: R
strong rubbing of the paintwork with
unsuitabl em aterialsR
frequent use of automatic car washes R
washing 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 suitabl ef or high-gloss surfaces. Their
use on vehicles with matte paintwork leads to
considerable surface damage or, more spe-
cifically ,tos hiny, spotted areas.
Alway sh ave paintwork repairs carried out at a
qualified specialist workshop.
! Do not use wash programs with ah ot wax
treatment under any circumstances.
Observe these notes if your vehicle has ac lear
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.
The vehicle should ideally be washed by hand
using as oft sponge, car shampoo and plenty of
water.
Use only insect remover and car shampoo from
the range of approved Mercedes-Benz care
products.
