1、汽车润滑系统的深化保养

1. Deepening maintenance of automotive lubrication systems

润滑系统主要作用就是对汽车发动机的各个部件进行有效的润滑，以防过度磨损。在常规情况下，BMW每行驶10000km时就需清洗保养一次，在遇到发动机噪音过大，加速无力，水温过高时也需清洗保养一次。清洗发动机内部的油泥和其它积物，避免机油高温下的氧化稠化，减少发动机部件的磨损，延长发动机寿命，提高发动机动力。

The main function of the lubrication system is to effectively lubricate the various components of the car engine to prevent excessive wear. Under normal circumstances, BMW needs to be cleaned and maintained every 10000km, and also needs to be cleaned and maintained when encountering excessive engine noise, weak acceleration, and high water temperature. Clean the oil sludge and other deposits inside the engine to avoid oxidation and thickening of the engine oil under high temperatures, reduce wear on engine components, extend engine life, and improve engine power.

2、汽车燃油系统的清洗保养

2. Cleaning and Maintenance of Automotive Fuel Systems

常规情况下，汽车每行驶10000km-15000km时需清洗保养1次，或当你发觉引擎喘抖，迟滞和加速不良，冒黑烟，无力、费油时清洗保养1次。系统内部的胶质和积碳，防止有害的腐蚀发生，避免并制止密封件和水箱的渗漏，彻底更换旧的冷却液。

Under normal circumstances, a car needs to be cleaned and maintained once every 10000km-15000km, or once when you notice the engine shaking, lagging, poor acceleration, black smoke, weakness, and fuel consumption. Clean the internal resin and carbon deposits of the system to prevent harmful corrosion, prevent and stop leakage of seals and water tanks, and thoroughly replace the old coolant.

3、汽车冷却系统的清洗保养

3. Cleaning and maintenance of automotive cooling systems

一般情况下，汽车在冬夏换季时应清洗保养一次，正常行驶中每6个月8个月清洗保养一次，或者遇水温过高、漏水、开锅时清洗保养一次。导致发动机过热的痕迹和水垢，防止有害的腐蚀发生，避免并制止密封件和水箱的渗漏，彻底更换旧的冷却液。

In general, cars should be cleaned and maintained once during the winter and summer seasons. During normal driving, they should be cleaned and maintained every 6 to 8 months, or when encountering high water temperature, leakage, or boiling. Remove traces and scale that cause engine overheating, prevent harmful corrosion, prevent and stop leakage of seals and water tanks, and thoroughly replace old coolant.

4、汽车变速箱的清洗保养

4. Cleaning and Maintenance of Automobile Transmission

BMW变速箱油是免维护的，不过还是建议6-10万更换一次。

BMW transmission oil is maintenance free, but it is still recommended to replace it every 60000 to 100000 kilometers.

5、汽车动力转向系统的清洗保养

5. Cleaning and Maintenance of Automotive Power Steering System

汽车每行驶40000km-45000km清洗需保养一次，或遇转向困难系统渗漏，更换动力转向机配件后，也须清洗保养一次。系统中有害的油泥、漆膜，低温时的转向困难，制止并预防动力转向液的渗漏，转向噪音，彻底更换旧的制动转向液。

The car needs to be cleaned and maintained every 40000km-4500km, or in case of steering difficulties or system leakage, after replacing the power steering gear accessories, it also needs to be cleaned and maintained once. Remove harmful sludge and paint film from the system, eliminate steering difficulties at low temperatures, prevent and prevent power steering fluid leakage, eliminate steering noise, and thoroughly replace old brake steering fluid.

6、汽车制动系统的清洗保养

6. Cleaning and maintenance of automotive braking systems

汽车每行驶50000km清洗保养一次，或遇ABS反应过早，过慢时清洗保养一次。系统中有害的油泥漆膜，超高温或超低温时工作失灵的危险，有效防止制动液变质过期，彻底更换旧的制动液。

The car should be cleaned and maintained every 50000km, or if the ABS reaction is too early or too slow, it should be cleaned and maintained once. Remove harmful sludge and paint films from the system, eliminate the danger of failure in operation at ultra-high or ultra-low temperatures, effectively prevent brake fluid from deteriorating and expiring, and completely replace old brake fluid.
