Offered recommendations assume independent performance of procedures of service of the car it the owner unlike the works which are carried out at car repair shop of representation office of the Mercedes-Benz company. Though this schedule is made on the basis of manufacturer recommendations, intervals between the majority of procedures at the discretion of the owner of the car can be reduced, for example, check and replacement of greasings and liquids should be made with the intervals providing the maximum service life of the engine or a drive. Besides, if the owner of the car is interested in supporting it in a condition of the maximum readiness for operation on a case of the possible resale, many procedures can be carried out more often. Originators of the real Management can greet a similar initiative only.

Initial service and check of the new car should be made at car repair shop of representation office of the Mercedes-Benz company for the purpose of performance of conditions of guarantee certificates. This service is provided free of charge.
