Mercedes-Benz W123 Instrucciones de Servicio Manual | PDF

Owner's manual for the six-cylinder petrol versions of the Mercedes-Benz W123 Series.

Introduced as the successor to the W114 and W115 sedans, the 123 Series opened a new chapter among Mercedes-Benz mid-size cars and became one of the brand's most recognizable model families. Its robust construction, ride comfort and emphasis on safety helped establish it as a direct predecessor to today's E-Class.

The range was later expanded with the C123 coupé, which retained the sedan's technical foundation while combining it with a two-door body, a shorter wheelbase and more sporting proportions. This manual covers versions of both body styles powered by the 2.8-liter M110 engine with either carburetion or fuel injection.

The instructions explain the operation of the controls, instruments and comfort equipment. They also cover starting, transmission operation, driving under different conditions and the checks needed to care for the vehicle correctly.

Operation and equipment

• Dashboard and instrument cluster.
• Keys, doors, central locking and child safety locks.
• Seats, head restraints, armrests and safety belts.
• Lights, headlamp-range adjustment and headlamp cleaning system.
• Cruise control and driving controls.
• Heating, ventilation and air conditioning.
• Sliding roof, electric windows and radio.
• Mirrors, sun visors, interior lights and heated rear window.

The cover, contents list and technical tables specifically identify all four versions, helping customers confirm that the manual matches the model and body style they are looking for before purchasing.

Driving and operation

The manual explains how to open the hood, perform regular checks, use the parking brake and start and stop the engine. It also contains instructions for operating the manual and automatic transmissions.

Safe-driving sections cover brake wear, essential fluid levels and warning indicators, fuel and engine-oil consumption, the initial driving period, winter operation, snow chains and traveling abroad.

Maintenance and vehicle care

The document describes the Mercedes-Benz maintenance system and the operations required under difficult service conditions. It covers engine oil and filter changes, automatic-transmission maintenance and recommendations for cleaning and preserving the vehicle.

Practical checks and troubleshooting

The instructions show how to change a wheel, check tire pressures and inspect the engine-oil, coolant and automatic-transmission fluid levels. They also cover the battery, fuses, spark plugs and bulb replacement.

Additional sections explain emergency operation of the sliding roof, emergency release of the fuel-filler flap, jump-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.

Technical data and service products

The final section provides separate specifications for carbureted and fuel-injected versions, vehicle identification information, filling capacities and recommendations for engine oils, fuels, brake fluid and coolant.
