一、嚴守保養周期，別讓愛車 “帶病上崗”

　　1、 Strictly adhere to the maintenance cycle and do not let your car go to work with illness

　　奔馳官方建議，新車首次保養在行駛 10000 公里時進行，之后每 20000 公里需進行一次常規保養。但這只是個基礎參考，在濟南這種交通狀況復雜、氣候多變的城市，如果經常遭遇擁堵路況，車輛頻繁啟停，發動機負荷加重，保養周期就應適當縮短；要是常在高溫天氣下行車，零部件受熱老化加快，也得提前安排保養。舉例來說，若車輛在夏天頻繁往返于市區與城郊，走走停停，實際行駛 15000 公里左右就該送去保養了，不然發動機內部積攢的雜質和磨損的碎屑，會像 “定時炸彈”，影響發動機性能，嚴重時甚至造成故障。

　　Mercedes Benz officials suggest that the first maintenance of the new car should be carried out after driving 10000 kilometers, and regular maintenance should be performed every 20000 kilometers thereafter. But this is just a basic reference. In a city like Jinan with complex traffic conditions and variable climate, if you frequently encounter congested road conditions, frequent starting and stopping of vehicles, and increased engine load, the maintenance cycle should be appropriately shortened; If you often drive in high temperature weather, the aging of components will accelerate due to heat, and maintenance needs to be arranged in advance. For example, if a vehicle frequently travels back and forth between urban and suburban areas in summer, stopping and starting, and actually travels about 15000 kilometers, it should be sent for maintenance. Otherwise, the impurities and wear debris accumulated inside the engine will act like a "time bomb", affecting engine performance and even causing malfunctions in severe cases.

　　二、精準把握保養項目，拒絕 “過度保養”

　　2、 Accurately grasp maintenance items and refuse 'excessive maintenance'

　　1. 機油與機油濾清器：發動機的 “保護神”

　　1. Engine oil and oil filter: the "protector" of the engine

　　每次保養，更換機油和機油濾清器是重中之重。奔馳發動機工藝精密，對機油品質要求極高，必須選用符合奔馳規格的全合成機油，像美孚 1 號金裝系列、嘉實多極護專享等，才能在高溫、高壓環境下，為發動機提供持久、穩定的潤滑，減少磨損。機油濾清器也別忽視，它負責過濾機油中的雜質，劣質濾清器過濾效果差，雜質進入發動機，會加劇零部件磨損。更換周期基本與機油同步，每 10000 公里左右就得換，確保機油始終 “干干凈凈”，讓發動機 “暢快呼吸”。

　　Every maintenance, changing the oil and oil filter is of utmost importance. Mercedes Benz engines have precise craftsmanship and extremely high requirements for oil quality. It is necessary to use fully synthetic engine oil that meets Mercedes Benz specifications, such as Mobil 1 Gold Series and Jia Shi Duo Extreme Protection Exclusive, in order to provide long-lasting and stable lubrication for the engine in high temperature and high pressure environments, reducing wear and tear. Don't ignore the oil filter, it is responsible for filtering impurities in the engine oil. Poor quality filters have poor filtering effects, and impurities entering the engine can exacerbate component wear. The replacement cycle is basically synchronized with the engine oil, which needs to be changed every 10000 kilometers to ensure that the engine oil is always "clean" and allows the engine to breathe freely.

　　2. 空氣濾清器：發動機的 “口罩”

　　2. Air filter: the "mask" of the engine

　　空氣濾清器就像發動機的 “口罩”，在濟南這樣灰塵、柳絮時有飛揚的城市，臟污的空氣濾清器會嚴重影響發動機進氣量，導致燃燒不充分，動力下降，油耗飆升。正常情況下，每 10000 公里左右就得檢查，若臟污嚴重，就得及時更換。比如春天柳絮漫天時，空氣濾清器很容易被柳絮堵塞，要是發現車輛加速無力、尾氣排放變濃，大概率就是空氣濾清器該換了。

　　The air filter is like the "mask" of the engine. In a city like Jinan where dust and willow catkins often fly, a dirty air filter can seriously affect the engine's intake, leading to insufficient combustion, decreased power, and soaring fuel consumption. Under normal circumstances, it is necessary to check every 10000 kilometers, and if the dirt is severe, it needs to be replaced in a timely manner. For example, when willow catkins fill the air in spring, the air filter is easily clogged by willow catkins. If you find that the vehicle accelerates weakly and the exhaust emissions become heavier, it is highly likely that the air filter needs to be replaced.

　　3. 制動系統：行車安全的 “命門”

　　3. Braking system: the "lifeline" of driving safety

　　制動系統關乎行車安全，來不得半點馬虎。保養時，要仔細檢查制動盤、剎車片磨損情況，正常剎車片厚度在 10 毫米左右，當磨損到 3 毫米以下，就得立即更換。制動液也得定期檢查、更換，一般每兩年一換，因為制動液有吸水性，時間長了含水量增加，沸點降低，高溫下容易產生氣阻，導致剎車失靈。另外，濟南冬季有時會下雪，路面濕滑，對制動系統要求更高，冬季來臨前，更要著重檢查制動系統狀態，確保關鍵時刻能剎得住車。

　　The braking system is crucial to driving safety and cannot be taken lightly. During maintenance, it is necessary to carefully inspect the wear of the brake discs and brake pads. The normal thickness of the brake pads is around 10 millimeters, but when the wear drops below 3 millimeters, they must be replaced immediately. Brake fluid also needs to be checked and replaced regularly, usually every two years, because brake fluid has water absorption properties. Over time, the water content increases, the boiling point decreases, and air resistance is easily generated at high temperatures, leading to brake failure. In addition, sometimes it snows in winter in Jinan, and the road surface is wet and slippery, which requires higher requirements for the braking system. Before the arrival of winter, it is even more important to check the status of the braking system to ensure that the vehicle can be stopped at critical moments.

　　4. 火花塞：發動機的 “點火器”

　　4. Spark plug: the "igniter" of the engine

　　火花塞的作用是點燃混合氣，為發動機提供動力。奔馳火花塞的更換周期因車型而異，普通車型每 60000 公里左右更換，缸內直噴車型則每 40000 公里左右就得換。要是火花塞老化、積碳，點火能量不足，發動機就會出現抖動、加速無力、油耗增加等問題，嚴重影響駕駛體驗，還可能損傷發動機，所以到了更換周期，千萬別拖延。

　　The function of a spark plug is to ignite the mixture and provide power to the engine. The replacement cycle of Mercedes Benz spark plugs varies depending on the vehicle model. For regular models, they need to be replaced every 60000 kilometers, while for direct injection models, they need to be replaced every 40000 kilometers. If the spark plug ages, accumulates carbon, and the ignition energy is insufficient, the engine will experience problems such as shaking, weak acceleration, and increased fuel consumption, which seriously affect the driving experience and may even damage the engine. Therefore, do not delay the replacement cycle.

　　5. 燃油濾清器：燃油系統的 “凈化器”

　　5. Fuel filter: the "purifier" of the fuel system

　　燃油濾清器負責過濾燃油中的雜質，保證燃油純凈，防止噴油嘴堵塞、油泵磨損。在國內油品參差不齊的情況下，奔馳車的燃油濾清器尤為重要，建議每 20000 公里更換一次，讓燃油系統始終處于最佳工作狀態，確保發動機穩定運行。

　　The fuel filter is responsible for filtering impurities in the fuel, ensuring fuel purity, and preventing nozzle blockage and pump wear. In the case of uneven oil quality in China, the fuel filter of Mercedes Benz cars is particularly important. It is recommended to replace it every 20000 kilometers to keep the fuel system in the best working condition and ensure stable engine operation.

　　6. 懸掛系統：駕乘舒適的 “保障”

　　6. Suspension system: a "guarantee" for comfortable driving and riding

　　濟南的道路難免有坑洼、減速帶，頻繁沖擊下，奔馳車的懸掛系統容易受損。保養時，要檢查懸掛系統的連接件、減震器是否松動、漏油，膠套是否老化。要是減震器漏油，車輛行駛時就會顛簸感加劇，過減速帶時震動明顯，不僅影響駕乘舒適性，還會影響車輛操控性，此時就得及時更換減震器，恢復懸掛系統的正常性能。

　　The roads in Jinan are inevitably bumpy and have speed bumps, which can easily damage the suspension system of Mercedes Benz cars under frequent impacts. During maintenance, it is necessary to check whether the connecting parts and shock absorbers of the suspension system are loose or leaking oil, and whether the rubber sleeve is aging. If the shock absorber leaks oil, the vehicle will experience increased jolting and noticeable vibrations when passing speed bumps, which not only affects driving comfort but also vehicle handling. At this time, it is necessary to replace the shock absorber in a timely manner to restore the normal performance of the suspension system.

　　7. 輪胎：行車安全的 “基石”

　　7. Tires: the cornerstone of driving safety

　　輪胎是車輛與地面唯一的接觸點，安全至關重要。在濟南，夏天高溫，冬天寒冷，輪胎受溫度影響較大。要定期檢查輪胎氣壓，一般標準氣壓在油箱蓋內側有標注，氣壓過高或過低，都會影響輪胎使用壽命和行車安全。同時，查看輪胎花紋磨損情況，花紋深度低于 1.6 毫米時，輪胎排水性能變差，雨天行車容易打滑，就得考慮更換輪胎。另外，每 10000 公里左右建議進行一次輪胎換位，讓輪胎磨損更均勻，延長使用壽命。

　　Tires are the only point of contact between a vehicle and the ground, and safety is crucial. In Jinan, it is hot in summer and cold in winter, and tires are greatly affected by temperature. Regularly check the tire pressure. The standard pressure is usually marked on the inside of the fuel tank cap. If the pressure is too high or too low, it will affect the service life of the tires and driving safety. At the same time, check the wear of tire tread patterns. When the tread depth is less than 1.6 millimeters, the tire drainage performance deteriorates, and it is easy to slip when driving on rainy days. Therefore, it is necessary to consider replacing the tire. Additionally, it is recommended to rotate the tires every 10000 kilometers to ensure even wear and extend their lifespan.
