奔驰汽车作为高端车型，其保养需要兼顾性能维护与精密部件的呵护。在济南，奔驰汽车的保养项目涵盖多个系统，每个项目都针对车辆的不同部件，通过定期检查、更换和调整，确保车辆始终处于良好状态，延长使用寿命，保障行驶安全。

　　As a high-end model, Mercedes Benz requires a balance between performance maintenance and the care of precision components in its maintenance. In Jinan, Mercedes Benz's maintenance projects cover multiple systems, each targeting different components of the vehicle. Through regular inspection, replacement, and adjustment, the vehicle is always in good condition, extending its service life and ensuring driving safety.

　　发动机系统的保养是车辆性能的核心保障。机油和机油滤清器的更换是基础项目，奔驰车型通常建议每 1 万公里或 12 个月更换一次机油，具体需根据使用的机油类型（全合成或半合成）和驾驶习惯调整。更换机油时需同时更换机油滤清器，防止旧滤清器内的杂质污染新机油，影响润滑效果。空气滤清器和空调滤清器也需定期检查，济南春季多风沙，空气滤清器易积累灰尘，若堵塞会导致发动机进气不足，燃烧效率下降，建议每 2 万公里更换一次；空调滤清器则关系到车内空气质量，尤其在夏季使用空调频繁时，每 1.5 万公里需检查，必要时更换，避免灰尘、霉菌进入车内。此外，发动机的火花塞需根据材质更换，铱金火花塞可使用 6-8 万公里，更换时需注意拧紧力矩，确保密封良好，防止漏气影响动力输出。

　　The maintenance of the engine system is the core guarantee of vehicle performance. The replacement of oil and oil filter is a basic project, and Mercedes Benz models usually recommend changing the oil every 10000 kilometers or 12 months, depending on the type of oil used (fully synthetic or semi synthetic) and driving habits. When changing the engine oil, it is necessary to replace the oil filter at the same time to prevent impurities in the old filter from contaminating the new engine oil and affecting the lubrication effect. Air filters and air conditioning filters also need to be regularly inspected. Jinan is prone to sandstorms in spring, and air filters are prone to accumulate dust. If clogged, it can lead to insufficient engine intake and decreased combustion efficiency. It is recommended to replace them every 20000 kilometers; The air conditioning filter is related to the air quality inside the car, especially when the air conditioning is frequently used in summer. It needs to be checked every 15000 kilometers and replaced if necessary to avoid dust and mold entering the car. In addition, the spark plugs of the engine need to be replaced according to the material. Iridium spark plugs can be used for 60000 to 80000 kilometers. When replacing, attention should be paid to tightening torque to ensure good sealing and prevent air leakage from affecting power output.

　　底盘系统的保养直接影响行驶稳定性和舒适性。刹车片和刹车盘是重点检查对象，奔驰车型的刹车片磨损极限通常为 3 毫米，当厚度接近极限时需及时更换，同时检查刹车盘的磨损情况，若出现划痕或不平，需进行光盘处理或更换。刹车油具有吸水性，长期使用会导致沸点下降，影响刹车效果，建议每 2 年或 4 万公里更换一次，更换时需排空系统内的空气，确保刹车管路通畅。轮胎的保养包括胎压检查和磨损监测，济南夏季气温高，需定期调整胎压至标准值（通常在 2.2-2.5bar 之间），避免胎压过高导致爆胎；轮胎花纹深度低于 1.6 毫米时需更换，同时注意轮胎的磨损均匀性，若出现偏磨，需及时做四轮定位，调整前轮前束和外倾角，防止轮胎过早报废。

　　The maintenance of the chassis system directly affects driving stability and comfort. Brake pads and brake discs are the key inspection objects. The wear limit of brake pads for Mercedes Benz models is usually 3 millimeters. When the thickness approaches the limit, they need to be replaced in a timely manner. At the same time, the wear of brake discs should be checked. If scratches or unevenness occur, disc treatment or replacement should be carried out. Brake oil has water absorption properties, and long-term use can lead to a decrease in boiling point, affecting braking effectiveness. It is recommended to replace it every 2 years or 40000 kilometers, and the air in the system should be emptied during replacement to ensure smooth brake pipelines. Tire maintenance includes tire pressure inspection and wear monitoring. Due to the high temperature in Jinan during summer, it is necessary to regularly adjust tire pressure to the standard value (usually between 2.2-2.5 bar) to avoid tire blowouts caused by excessive tire pressure; When the tire tread depth is less than 1.6 millimeters, it needs to be replaced. At the same time, attention should be paid to the uniformity of tire wear. If there is uneven wear, it is necessary to perform four-wheel alignment in a timely manner, adjust the front wheel toe in and camber angle, and prevent premature tire scrapping.

　　电气系统的保养关乎车辆功能的正常运转。蓄电池的使用寿命通常为 3-5 年，需定期检查电量和电极桩头，若桩头出现氧化，可用热水冲洗后涂抹凡士林，防止腐蚀。济南冬季寒冷，蓄电池容量会有所下降，进入冬季前需检测电量，避免因电量不足导致启动困难。车辆的灯光系统也需全面检查，包括大灯、转向灯、刹车灯、倒车灯等，确保灯光亮度充足、闪烁频率正常，若发现灯泡损坏，需及时更换同型号灯泡，尤其奔驰车型的 LED 大灯，更换时需注意线路连接，避免短路。此外，雨刮器的保养不可忽视，每 6 个月需检查雨刮片的磨损情况，若出现刮水不清或异响，需及时更换，同时定期添加玻璃水，尤其是冬季需使用防冻型玻璃水，防止结冰损坏水壶。

　　The maintenance of electrical systems is related to the normal operation of vehicle functions. The service life of batteries is usually 3-5 years. It is necessary to regularly check the battery level and electrode tips. If the tips oxidize, they can be rinsed with hot water and coated with Vaseline to prevent corrosion. Jinan is cold in winter, and the battery capacity may decrease. Before entering winter, it is necessary to check the battery level to avoid difficulties in starting due to insufficient power. The vehicle's lighting system also needs to be thoroughly inspected, including headlights, turn signals, brake lights, reverse lights, etc., to ensure sufficient brightness and normal flashing frequency. If damaged bulbs are found, they should be replaced with bulbs of the same model in a timely manner, especially the LED headlights of Mercedes Benz models. When replacing, attention should be paid to the wiring connection to avoid short circuits. In addition, the maintenance of wipers cannot be ignored. The wear of wiper blades should be checked every 6 months. If there is unclear wiping or abnormal noise, it should be replaced in a timely manner. At the same time, glass water should be added regularly, especially in winter, antifreeze glass water should be used to prevent freezing and damage to the kettle.

　　车身和内饰的保养能保持车辆的美观和使用舒适度。车身漆面的保养包括定期清洗和打蜡，济南夏季紫外线强，雨水含酸性物质，长期不保养会导致漆面氧化、褪色，建议每 3 个月打一次蜡，形成保护膜，隔绝外界侵蚀。车门密封条若出现老化、开裂，会导致隔音效果下降和雨水渗漏，需定期涂抹密封条养护剂，保持弹性。内饰方面，真皮座椅需使用专用清洁剂清洁，避免使用碱性强的洗涤剂导致皮质变硬；中控台和仪表盘可使用内饰蜡擦拭，防止塑料件老化开裂。此外，后备箱和车门储物格内的排水孔需定期疏通，济南雨季多雨，若排水孔堵塞会导致积水，损坏车内电器元件。

　　The maintenance of the body and interior can maintain the beauty and comfort of the vehicle. The maintenance of the car's paint surface includes regular cleaning and waxing. In Jinan, the summer UV rays are strong, and rainwater contains acidic substances. Long term neglect of maintenance can cause the paint surface to oxidize and fade. It is recommended to apply wax every 3 months to form a protective film and isolate external erosion. If the door sealing strip ages or cracks, it will lead to a decrease in sound insulation effect and rainwater leakage. It is necessary to regularly apply sealing strip maintenance agent to maintain elasticity. In terms of interior, leather seats need to be cleaned with specialized cleaning agents to avoid using alkaline detergents that can cause the leather to harden; The center console and dashboard can be wiped with interior wax to prevent plastic parts from aging and cracking. In addition, the drainage holes in the trunk and door storage compartments need to be regularly unblocked. During the rainy season in Jinan, if the drainage holes are blocked, it will cause water accumulation and damage to the electrical components inside the car.
