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 available at your
authorized Mercedes-Benz dealer. Please follow service Booklet recommendations for scheduled oil
changes. 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 point of the brake fluid is continuously reduced through the
absorption of moisture from the atmosphere. Under extremely hard operating conditions, this
moisture content can lead to the formation of bubbles in the system thus reducing the system's
efficiency.
The brake fluid must therefore be replaced every two years, preferably in the spring. It is
recommended to use only brake fluid approved by Mercedes- Benz. Your authorized Mercedes-
Benz dealer will provide you with additional information.
