Schedule of current maintenance (Mercedes-Benz S-Class W140)

Contents: Engine oil change and related work ↡ Additional works ↡

The suggested recommendations assume that the vehicle is serviced by the owner himself, as opposed to work performed at a Mercedes-Benz dealership service station. Although this schedule is based on the manufacturer's recommendations, the intervals between most of the procedures can be shortened at the owner's discretion, for example, checking and changing lubricants and fluids should be performed at intervals that ensure maximum engine or drive life. In addition, if the owner is interested in keeping the vehicle in maximum operating condition for possible resale, many procedures can be performed more frequently. We welcome such an initiative.

Initial servicing and inspection of a new vehicle must be performed at a representative service station of the company in order to fulfill the terms of the warranty obligation. Such inspection is free of charge.

Attention! Be careful when working in the engine compartment, the cooling system fan may continue to operate for about 30 seconds after the engine is turned off!

Warning! The electronic ignition system generates very high voltage! Be careful and take all necessary precautions when servicing any components of the system, including not only the main (ignition module, coil and high voltage wires), but also related ones, such as spark plug connectors, tachometer and other connected diagnostic equipment. Particular care should be taken when the engine is running, during its start-up, with the ignition on (key in position 2) and when turning the crankshaft manually. Persons with an implanted pacemaker should not be allowed to service ignition system components!
