Mercedes-Benz 300D 2.5 1990 Owner's Manual page 20

Kindly observe the following in your own best interests:
We recommend using MERCEDES-BENZ original parts as
well as conversion parts and accessories explicitly approved
by us for your vehicle model.
We have subjected these parts to a special test in which
their reliability, safety and their special suitability for
MERCEDES-BENZ vehicles have been determined.
We are unable to make an assessment for other products
and therefore cannot be held responsible for them, even if in
individual cases an official approval or authorization by
governmental or approval agencies should exist.
MERCEDES-BENZ original parts as well as conversion
parts and accessories approved by us are available at your
MERCEDES-BENZ service station where you will receive
comprehensive information, also on permissible technical
modifications, and where expert installation will be per­
formed.
