Mercedes-Benz tests genuine parts as well as

been specifically approved for your vehicle for
their reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benz is
unable to assess other parts. Therefore,
Mercedes-Benz accepts no responsibility for
the use of such parts in Mercedes-Benz
vehicles. This is also the case, even if they
have been independently or officially
approved. The use of non-approved parts
could affect your vehicle's operating safety.
Genuine Mercedes-Benz parts, approved
conversion parts and accessories are
available from any authorized Mercedes-Benz
Center. Here, you will receive advice about
permissible technical modifications, and the
parts will be professionally installed. Operator's Manual
