机油与机油滤清器更换​

Oil and oil filter replacement

机油如同汽车发动机的 “血液”，定期更换至关重要。奔驰车型通常建议每 10000 公里或 1 年（以先到者为准）更换机油。在济南的气候条件下，若车辆经常在拥堵市区行驶，发动机长时间处于高温高负荷状态，机油劣化速度加快，可适当缩短更换周期至 8000 公里左右。更换机油时，必须同时更换机油滤清器，以过滤机油中的杂质，防止其进入发动机内部造成磨损。奔驰原厂机油滤清器采用优质滤纸，过滤精度高，能有效拦截微小颗粒，确保机油清洁。例如，在奔驰 C 级保养中，使用符合奔驰认证标准的全合成机油，能显著提升发动机性能，降低噪音与振动。​

Engine oil is like the "blood" of a car engine, and regular replacement is crucial. Mercedes Benz models usually recommend changing the oil every 10000 kilometers or 1 year (whichever comes first). In the climate conditions of Jinan, if vehicles often drive in congested urban areas and the engine is in a high-temperature and high load state for a long time, the deterioration rate of the oil will accelerate, and the replacement cycle can be appropriately shortened to about 8000 kilometers. When changing the engine oil, the oil filter must be replaced at the same time to filter out impurities in the oil and prevent them from entering the engine interior and causing wear. The Mercedes Benz original oil filter uses high-quality filter paper with high filtration accuracy, which can effectively intercept small particles and ensure the cleanliness of the oil. For example, in Mercedes Benz C-Class maintenance, using fully synthetic engine oil that meets Mercedes Benz certification standards can significantly improve engine performance, reduce noise and vibration. ​

空气滤清器与空调滤清器清洁 / 更换​

Cleaning/replacement of air filter and air conditioning filter

空气滤清器负责过滤进入发动机的空气，若其堵塞，会使发动机进气量不足，导致燃烧不充分，动力减弱，油耗上升。在济南这样空气质量时有变化的城市，建议每 15000 公里检查空气滤清器，若较脏则及时更换。空调滤清器则关乎车内空气质量，它能过滤空气中的灰尘、花粉、异味及有害颗粒等。尤其在花粉季或雾霾天气较多的时节，更要关注空调滤清器状态，一般每 10000 公里或根据实际使用情况进行清洁或更换。奔驰原厂空调滤清器具备高效的过滤能力，部分还带有活性炭层，可有效吸附异味与有害气体，为车内营造清新舒适的环境。比如在花粉季来临前，及时更换空调滤清器，能避免花粉进入车内，让车内乘客免受过敏困扰。​

The air filter is responsible for filtering the air entering the engine. If it is clogged, it will cause insufficient intake of air into the engine, resulting in incomplete combustion, reduced power, and increased fuel consumption. In a city like Jinan where air quality changes from time to time, it is recommended to check the air filter every 15000 kilometers and replace it promptly if it is dirty. The air conditioning filter is related to the air quality inside the car. It can filter out dust, pollen, odors, and harmful particles in the air. Especially during the pollen season or when there is a lot of haze, it is important to pay attention to the condition of the air conditioning filter. Generally, it should be cleaned or replaced every 10000 kilometers or according to actual usage. Mercedes Benz's original air conditioning filters have efficient filtering capabilities, and some even have activated carbon layers that can effectively absorb odors and harmful gases, creating a fresh and comfortable environment inside the car. For example, replacing the air conditioning filter in a timely manner before the pollen season can prevent pollen from entering the car and protect passengers from allergies. ​

轮胎检查与换位​

Tire inspection and rotation

轮胎是汽车与地面接触的唯一部件，其状态直接影响行车安全。在济南，道路状况多样，定期检查轮胎至关重要。每次保养时，需检查轮胎花纹深度，一般花纹深度低于 1.6 毫米时就需更换轮胎。同时，要检查轮胎气压是否正常，奔驰车辆的轮胎气压标准通常标注在车门边框或车辆使用手册上。此外，为使轮胎磨损均匀，延长使用寿命，建议每 10000 - 15000 公里进行一次轮胎换位，前后轮交叉换位是常见方式。例如，在对奔驰 E 级进行保养时，通过专业的轮胎检测设备，能精准测量轮胎气压与花纹深度，确保轮胎处于良好状态。

Tires are the only components of a car that come into contact with the ground, and their condition directly affects driving safety. In Jinan, the road conditions are diverse, and regular tire inspections are crucial. During each maintenance, it is necessary to check the depth of the tire tread pattern. Generally, if the tread depth is less than 1.6 millimeters, the tire needs to be replaced. At the same time, it is necessary to check whether the tire pressure is normal. The tire pressure standard for Mercedes Benz vehicles is usually marked on the door frame or vehicle manual. In addition, to ensure even tire wear and extend service life, it is recommended to perform tire rotation every 10000-15000 kilometers, with front and rear wheel cross rotation being a common method. For example, during maintenance of the Mercedes Benz E-Class, professional tire inspection equipment can accurately measure tire pressure and tread depth to ensure that the tires are in good condition.
