在济南驾驶奔驰，想要长久保持卓越性能，精心保养必不可少。奔驰的保养涵盖核心系统到细节部件，每一项都直接影响车辆的性能、安全与寿命。

　　To maintain excellent performance for a long time while driving a Mercedes Benz in Jinan, careful maintenance is essential. Mercedes Benz maintenance covers core systems to detailed components, each of which directly affects the performance, safety, and lifespan of the vehicle.

　　发动机：汽车的 “心脏” 养护

　　Engine: the "heart" maintenance of automobiles

　　发动机保养是关键。建议每 7500 - 10000 公里或 1 年，更换符合奔驰规格的全合成机油与机滤，充分润滑发动机，减少磨损。济南空气质量复杂，空气滤清器需每 15000 公里左右检查清洁，过脏即换，确保燃油充分燃烧。火花塞则依据发动机类型，在 3 - 6 万公里左右更换，维持稳定点火，保障动力输出。

　　Engine maintenance is crucial. It is recommended to replace the fully synthetic engine oil and filter that meet Mercedes Benz specifications every 7500-10000 kilometers or 1 year, fully lubricate the engine, and reduce wear. The air quality in Jinan is complex, and the air filter needs to be checked and cleaned every 15000 kilometers. If it is too dirty, it should be replaced to ensure that the fuel is fully burned. Spark plugs are replaced at around 30000 to 60000 kilometers depending on the engine type to maintain stable ignition and ensure power output.

　　制动系统：安全的 “坚固防线”

　　Braking System: A Secure 'Sturdy Line of Defense'

　　制动系统关乎行车安全。刹车片厚度小于 3 毫米时必须更换；刹车盘若出现明显划痕、变形，需及时修复或更换。制动液具有吸水性，每 2 年或 4 万公里需更换，避免因沸点降低影响制动效果，确保各种工况下刹车可靠。

　　The braking system is related to driving safety. When the thickness of the brake pad is less than 3 millimeters, it must be replaced; If there are obvious scratches or deformations on the brake disc, it should be repaired or replaced in a timely manner. Brake fluid has water absorption properties and needs to be replaced every 2 years or 40000 kilometers to avoid affecting the braking effect due to a decrease in boiling point and ensure reliable braking under various working conditions.

　　轮胎：平稳行驶的 “守护者”

　　Tires: the "guardians" of smooth driving

　　轮胎保养不容忽视。需定期检查气压，气压异常会影响轮胎寿命与行驶性能。观察花纹深度，小于 1.6 毫米时应更换；同时留意鼓包、裂缝等异常。每 10000 - 15000 公里进行轮胎换位，可让磨损更均匀，延长使用周期。

　　Tire maintenance cannot be ignored. Regularly check the air pressure, as abnormal air pressure can affect tire life and driving performance. Observe the depth of the pattern, and replace it if it is less than 1.6 millimeters; Also pay attention to abnormalities such as bulges and cracks. Changing tires every 10000-15000 kilometers can make wear more uniform and extend the service life.

　　空调系统：舒适驾乘的 “保障者”

　　Air conditioning system: the "guarantor" of comfortable driving and riding

　　空调系统影响驾乘舒适度。空调滤清器每年至少更换一次，若常处于空气质量差的环境，更换频率应增加。此外，还需定期清洁杀菌，清除内部细菌、异味，营造健康清新的车内空间。

　　The air conditioning system affects driving comfort. The air conditioning filter should be replaced at least once a year. If it is often in an environment with poor air quality, the frequency of replacement should be increased. In addition, regular cleaning and sterilization are necessary to remove internal bacteria and odors, creating a healthy and fresh interior space.

　　电气系统：车辆的 “神经维护”

　　Electrical System: "Neural Maintenance" of Vehicles

　　电气系统保养也很重要。电瓶每 2 年左右检查，4 - 5 年更换，防止车辆无法启动。同时，定期检查照明、中控、音响等电子设备，确保线路无松动、破损，功能正常。

　　Electrical system maintenance is also important. The battery should be checked every 2 years and replaced every 4-5 years to prevent the vehicle from failing to start. At the same time, regularly inspect electronic equipment such as lighting, central control, and audio to ensure that the wiring is not loose, damaged, and functioning properly.

　　底盘与悬挂：稳定行驶的 “根基”

　　Chassis and suspension: the foundation of stable driving

　　底盘与悬挂系统是车辆稳定行驶的关键。定期检查底盘部件磨损、松动情况，及时更换传动轴、球头、减震器等受损件。检查悬挂系统弹簧、减震器等部件，确保其正常缓冲路面颠簸。每 20000 公里或按需进行四轮定位，避免跑偏与轮胎偏磨，提升操控性与安全性。

　　The chassis and suspension system are the key to stable driving of vehicles. Regularly inspect the wear and looseness of chassis components, and promptly replace damaged parts such as transmission shafts, ball joints, shock absorbers, etc. Check the suspension system springs, shock absorbers, and other components to ensure that they properly cushion road bumps. Perform four-wheel alignment every 20000 kilometers or as needed to avoid deviation and tire wear, and improve handling and safety.
