Engine Oils
Engine oils are specifically tested for their suitability in our engines. Therefore, use only engine oils recommended by
Mercedes-Benz. Information on recommended brands is av ailable at your authorized Mercedes-Benz dealer. Please
follow service Booklet recommendations for scheduled oil ch anges. Failure to do so could result in engine damage
not covered by the Mercedes-Benz Limited Warranty.
Engine Oil Additives
Do not blend oil additives with engine oil. They may be harmful to the engine operation. Damage or malfunctions
resulting from blending oil additives are not covered by the Mercedes-Benz Limited Warranty.
Air Conditioner Refrigerant
R-134a (HFC) refrigerant and special PAG lubricating oil is used in the air conditioner system. Never use R-12 (CFC)
or mineral based lubricating oil, otherwise damage to the system will occur.
Brake Fluid
During vehicle operation, the boiling poin t of the brake fluid is continuously reduced through the absorption of
moisture from the atmosphere. Under extremely hard operati ng conditions, this moisture content can lead to the
formation of bubbles in the system thus reducing the syste m's efficiency. The brake fluid must therefore be replaced
every two years, preferably in the spring. It is recomm ended to use only brake fluid approved by Mercedes- Benz.
Your authorized Mercedes Benz dealer will provide you with additional information.
