Lubricant additives ! Do not mix any lubricant additives with the engine oil. This could damage the engine. Damage resulting from the use of such lubricant additives in the engine oil is not covered by the Mercedes-Benz Limited Warranty. Engine oil viscosity Viscosity describes the flow characteristics of a fluid. If an engine oil has a high viscosity, this means that it is thick; a low viscosity means that it is thin. Using the table below, make sure that the SAE classification (viscosity) is sufficient for the temperatures at which the vehicle is operated. The low temperature characteristics of engine oils can deteriorate significantly, e.g by aging, soot and fuel deposits. It is therefore recommended that you carry out oil changes regularly using an approved engine oil with the appropriate SAE classification. Refrigerant of the air-conditioning system The air-conditioning system is filled with R134a refrigerant and a special PAG lubricant. ! Never use refrigerant R 12 (CFC) or mineral lubricants. Otherwise, you could damage the air-conditioning system. Brake fluid G Warning! The brake fluid constantly absorbs moisture from the air; this lowers its boiling point. If the boiling point of the brake fluid is too low, vapor pockets may form in the brake system when the brakes are applied hard (e.g. when driving downhill). This would impair braking efficiency. You should have the brake fluid renewed at regular intervals. The brake fluid change intervals can be found in the Service Booklet. Technical data Only use brake fluid approved by MercedesBenz. Information about approved brake fluids can be obtained from any authorized Mercedes-Benz Center. 36 BlueEFFICIENCY. 37 Restriction: only SAE 0W-40 engine oils may be used.
