natural product and is therefore subject to
a natural aging process. Leather

or high temperature by showing wrinkles
for example.
Wipe leather upholstery with a damp
cloth and dry thoroughly or clean with
Mercedes-Benz approved Leather

perforated leather as its underside should
not become wet.Wood trims
