Owner's manual specifically covering the diesel-powered versions of the Mercedes-Benz W115 Series.
Introduced in 1968, the W115 formed part of the generation of Mercedes-Benz sedans known as the “Stroke Eight.” Regarded as a predecessor to today's E-Class, the series became known for its durable construction, functional design and range of engines focused on reliability and economical operation.
The development of this diesel family included the four-cylinder OM 616 and the five-cylinder OM 617. The latter represented an important advance in Mercedes-Benz diesel passenger-car history and is identified as the 300 D in this documentation.
The manual explains the operation of the vehicle's controls, instruments and equipment. It also provides instructions for starting and stopping each engine, using the transmissions, driving safely and performing the checks needed to care for the vehicle.
The cover, starting instructions and technical tables specifically identify both versions, helping customers confirm that the manual matches the model they are looking for before purchasing.
The document describes the Mercedes-Benz maintenance system and the operations recommended for severe operating conditions. It includes information about engine oil changes, oil-filter servicing and automatic-transmission maintenance.
It also explains vehicle cleaning and preservation, care for different surfaces and routine checks involving the wheels, tires and fuel system.
The manual explains how to check the engine oil, coolant and automatic-transmission fluid. It also covers fuses, the battery, bulb replacement and emergency operation of the electric sliding roof.
Additional sections describe bleeding the fuel system, manually turning off the five-cylinder engine, using the high-altitude correction device, emergency starting and towing the vehicle.
These instructions are useful for answering routine questions and recognizing possible problems, but they do not replace the repair, disassembly or adjustment procedures found in a workshop manual.
The technical section provides separate specifications for each version, vehicle identification data, filling capacities and recommendations for engine oils, diesel fuel, brake fluid, coolant and antifreeze.
This contents list presents the operating instructions, driving guidance, maintenance information and technical data included in the Mercedes-Benz W115 Owner's Manual.
Section titles are retained in the manual's original language to preserve its organization and technical terminology.
