在济南，奔驰车主们对爱车呵护备至，而合理的保养项目则是维持奔驰卓越性能的关键。奔驰汽车的保养项目丰富且精细，如同为爱车量身定制的 “健康套餐”，每一项都关乎车辆的状态与寿命。

　　In Jinan, Mercedes Benz owners take great care of their cars, and reasonable maintenance projects are the key to maintaining Mercedes Benz's excellent performance. Mercedes Benz's maintenance program is rich and detailed, like a tailor-made "health package" for your beloved car, each item is related to the condition and lifespan of the vehicle.

　　基础保养中，机油与机油滤清器更换是核心环节。机油堪称发动机的 “血液”，在发动机运转时，发挥着润滑、冷却、清洁和防锈等重要作用。奔驰发动机对机油品质要求严苛，高品质的合成机油能在高温、高压等极端工况下，依然保持良好的流动性和润滑性，有效减少发动机内部部件的磨损。随着发动机持续工作，机油会混入金属碎屑、灰尘等杂质，性能逐渐下降，机油滤清器也会因过滤杂质而堵塞，所以按照规定周期更换机油与机滤极为重要。通常，济南的奔驰车若使用普通机油，建议每 1 万公里或 1 年更换一次；若选用高品质全合成机油，更换周期可适当延长至 1.5 万公里，但具体还需结合车辆实际使用频率与工况来确定。

　　In basic maintenance, the replacement of engine oil and oil filter is the core link. Engine oil can be called the "blood" of the engine, playing important roles in lubrication, cooling, cleaning, and rust prevention during engine operation. Mercedes Benz engines have strict requirements for the quality of engine oil. High quality synthetic engine oil can maintain good fluidity and lubricity under extreme working conditions such as high temperature and high pressure, effectively reducing the wear of internal engine components. As the engine continues to operate, the oil will mix with metal debris, dust, and other impurities, leading to a gradual decline in performance. The oil filter will also become clogged due to filtering impurities, so it is extremely important to replace the oil and filter according to the prescribed cycle. Usually, if Mercedes Benz cars in Jinan use regular engine oil, it is recommended to replace it every 10000 kilometers or 1 year; If high-quality fully synthetic engine oil is selected, the replacement cycle can be appropriately extended to 15000 kilometers, but the specific needs to be determined based on the actual frequency and working conditions of the vehicle.

　　空气滤清器的保养同样不可忽视。它如同发动机的 “口罩”，负责过滤进入发动机的空气，防止灰尘、沙粒等杂质进入气缸。在济南，若车辆经常行驶在路况复杂、灰尘较多的区域，空气滤清器更容易变脏。脏污的空气滤清器会阻碍空气流通，导致发动机进气量不足，进而影响燃烧效率，使车辆动力下降、油耗增加。一般情况下，空气滤清器每 2 万公里或 2 年需更换一次，不过在恶劣环境下使用的车辆，应适当缩短更换周期。定期清洁或更换空气滤清器，能让发动机始终 “呼吸” 到清洁的空气，维持良好的工作状态。

　　The maintenance of air filters cannot be ignored. It is like the "mask" of the engine, responsible for filtering the air entering the engine and preventing impurities such as dust and sand from entering the cylinder. In Jinan, if vehicles frequently travel in areas with complex road conditions and high levels of dust, the air filter is more likely to become dirty. A dirty air filter can hinder air circulation, resulting in insufficient engine intake, which in turn affects combustion efficiency, reduces vehicle power, and increases fuel consumption. In general, the air filter needs to be replaced every 20000 kilometers or 2 years, but for vehicles used in harsh environments, the replacement cycle should be appropriately shortened. Regularly cleaning or replacing the air filter can keep the engine breathing clean air and maintaining good working condition.

　　空调滤清器关乎车内驾乘人员的健康与舒适体验。它能过滤进入车内的空气，阻挡灰尘、花粉、细菌以及有害气体等。在济南，季节更替时花粉较多，空气质量也会有所变化，此时空调滤清器的作用愈发凸显。若空调滤清器长时间未更换，不仅会使空调出风量变小、制冷制热效果变差，还可能滋生细菌，产生异味，影响车内空气质量。建议每 1 - 2 万公里或每年更换一次空调滤清器，对于车内有老人、小孩等易感人群，以及在雾霾天气频繁区域行驶的车辆，更要增加更换频率，为车内营造清新、健康的空气环境。

　　The air conditioning filter is related to the health and comfort experience of the occupants in the car. It can filter the air entering the car, blocking dust, pollen, bacteria, and harmful gases. In Jinan, when the seasons change, there is more pollen and the air quality also changes. At this time, the role of air conditioning filters becomes increasingly prominent. If the air conditioning filter is not replaced for a long time, not only will the air conditioning output decrease and the cooling and heating effects deteriorate, but it may also breed bacteria, produce odors, and affect the air quality inside the car. It is recommended to replace the air conditioning filter every 10000 to 20000 kilometers or annually. For vehicles with susceptible populations such as the elderly and children, as well as those driving in areas with frequent haze weather, the frequency of replacement should be increased to create a fresh and healthy air environment inside the car.

　　刹车系统是行车安全的关键保障，其保养至关重要。奔驰车的刹车系统性能卓越，但随着使用，刹车油会吸收空气中的水分，导致沸点降低，影响刹车性能。刹车盘与刹车片在频繁制动过程中也会逐渐磨损。济南的奔驰车主应定期检查刹车油液位与品质，每 2 年或 6 万公里更换刹车油，以确保刹车系统的可靠性。同时，每次保养时都要仔细检查刹车盘与刹车片的磨损情况，一般来说，刹车片的更换周期约为 3 - 6 万公里，刹车盘的更换周期相对较长，约为 6 - 12 万公里，但具体需依据实际驾驶习惯与路况而定。一旦发现刹车盘磨损严重、刹车片厚度不足，应及时更换，避免因刹车问题引发安全事故。

　　The braking system is a key guarantee for driving safety, and its maintenance is crucial. The braking system of Mercedes Benz cars has excellent performance, but with use, the brake fluid will absorb moisture from the air, causing a decrease in boiling point and affecting braking performance. The brake disc and brake pads will gradually wear out during frequent braking. Mercedes Benz owners in Jinan should regularly check the brake fluid level and quality, and replace the brake fluid every 2 years or 60000 kilometers to ensure the reliability of the brake system. At the same time, it is necessary to carefully check the wear of the brake discs and brake pads during each maintenance. Generally speaking, the replacement cycle of brake pads is about 30000 to 60000 kilometers, and the replacement cycle of brake discs is relatively long, about 60000 to 120000 kilometers, but it depends on actual driving habits and road conditions. Once severe wear of the brake disc and insufficient thickness of the brake pads are found, they should be replaced in a timely manner to avoid safety accidents caused by braking problems.

　　此外，火花塞、变速箱油、轮胎等部件的保养也不容忽视。火花塞负责点燃发动机内的混合气，使用一段时间后，电极会磨损，点火性能下降，可能导致发动机抖动、加速无力、油耗增加等问题。不同车型的火花塞更换周期有所差异，一般为 2 - 6 万公里。变速箱油起到润滑、冷却和传递动力的作用，自动变速箱油通常每 4 - 6 万公里更换，手动变速箱油更换周期相对较长，约为 6 - 10 万公里。轮胎作为车辆与地面接触的唯一部件，关乎行车安全，要定期检查轮胎气压、磨损情况，每 6 - 8 万公里考虑更换轮胎，并定期进行轮胎换位，使轮胎磨损均匀，延长使用寿命。

　　In addition, the maintenance of components such as spark plugs, transmission oil, and tires cannot be ignored. Spark plugs are responsible for igniting the mixture inside the engine. After a period of use, the electrodes will wear out and the ignition performance will decrease, which may lead to engine shaking, weak acceleration, increased fuel consumption, and other problems. The replacement cycle of spark plugs varies among different vehicle models, generally ranging from 20000 to 60000 kilometers. Transmission oil plays a role in lubrication, cooling, and power transmission. Automatic transmission oil is usually replaced every 40000 to 60000 kilometers, while manual transmission oil has a relatively long replacement cycle, about 60000 to 100000 kilometers. As the only component that comes into contact with the ground, tires are crucial for driving safety. It is necessary to regularly check tire pressure and wear, consider replacing tires every 60000 to 80000 kilometers, and regularly rotate tires to ensure even wear and extend their service life.
