Please follow Maintenance System recommendations for scheduled oil changes. Failure to do so could result in engine or emission control system damage not covered by the Mercedes-Benz Limited Warranty. Brake fluid Warning! G Engine oil additives ! Do not blend oil additives with engine oil. They may damage the engine. Damage or malfunctions resulting from blending oil additives are not covered by the Mercedes-Benz Limited Warranty.

During vehicle operation, the boiling point of the brake fluid is continuously reduced through the absorption of moisture from the atmosphere. Under extremely strenuous operating conditions, this moisture content can lead to the formation of bubbles in the system, thus reducing the system's efficiency. Therefore, the brake fluid must be replaced regularly. Refer to your vehicle's Maintenance Booklet for replacement interval. ! Never use R-12 (CFC) or mineral-based lubricating oil. Otherwise damage to the system will occur. Only brake fluid approved by Mercedes-Benz is recommended. Any authorized Mercedes-Benz Center will provide you with additional information. 450
