在高端汽車領(lǐng)域，奔馳以精密工程與卓越性能著稱，其保養(yǎng)維護(hù)需建立科學(xué)化、精細(xì)化的養(yǎng)護(hù)體系。從機(jī)械系統(tǒng)到電子模塊，從常規(guī)保養(yǎng)到深度養(yǎng)護(hù)，車主需掌握六大核心維度，確保車輛始終處于最佳狀態(tài)。

　　In the high-end automotive field, Mercedes Benz is known for its precision engineering and excellent performance, and its maintenance requires the establishment of a scientific and refined maintenance system. From mechanical systems to electronic modules, from routine maintenance to deep maintenance, car owners need to master six core dimensions to ensure that their vehicles are always in optimal condition.

　　一、養(yǎng)護(hù)周期的精準(zhǔn)把控

　　1、 Accurate control of maintenance cycle

　　奔馳官方保養(yǎng)手冊(cè)將保養(yǎng)周期分為A保、B保兩大類：

　　The official maintenance manual of Mercedes Benz divides the maintenance cycle into two categories: A maintenance and B maintenance:

　　A保（基礎(chǔ)保養(yǎng)）

　　A Guarantee (Basic Maintenance)

　　每行駛1萬(wàn)公里或12個(gè)月進(jìn)行，核心項(xiàng)目包括機(jī)油機(jī)濾更換、全車油液檢查、輪胎氣壓校正等。采用低粘度全合成機(jī)油，可提升燃油經(jīng)濟(jì)性3%-5%。

　　Every 10000 kilometers or 12 months of driving, the core projects include oil filter replacement, full vehicle oil inspection, tire pressure correction, etc. Using low viscosity fully synthetic engine oil can improve fuel economy by 3% -5%.

　　B保（深度保養(yǎng)）

　　B Guarantee (Deep Maintenance)

　　每行駛2萬(wàn)公里或24個(gè)月實(shí)施，涵蓋空氣濾清器、空調(diào)濾清器、剎車油、火花塞等18項(xiàng)檢測(cè)更換。在渦輪增壓車型中，需額外進(jìn)行中冷器清潔與增壓管路檢查。

　　Implemented every 20000 kilometers or 24 months, covering 18 tests and replacements such as air filters, air conditioning filters, brake oil, spark plugs, etc. In turbocharged models, additional cleaning of the intercooler and inspection of the boost pipeline are required.

　　二、關(guān)鍵系統(tǒng)的專項(xiàng)養(yǎng)護(hù)

　　2、 Special maintenance of critical systems

　　對(duì)核心部件實(shí)施預(yù)防性維護(hù)，可延長(zhǎng)使用壽命：

　　Implementing preventive maintenance on core components can extend their service life:

　　動(dòng)力總成養(yǎng)護(hù)

　　Powertrain maintenance

　　采用縱置布局的發(fā)動(dòng)機(jī)，需每3萬(wàn)公里進(jìn)行缸內(nèi)積碳清洗。使用核桃砂物理清洗技術(shù)，避免化學(xué)清洗劑對(duì)氧傳感器的腐蝕，恢復(fù)發(fā)動(dòng)機(jī)壓縮比至設(shè)計(jì)值±2%。

　　The 9-speed automatic transmission requires the replacement of specialized oil every 60000 kilometers, using an equal amount exchange method to ensure accurate oil filling to ± 0.2L. For four-wheel drive models, it is necessary to check the transfer case oil level and the integrity of the transmission shaft dust cover.

　　底盤系統(tǒng)調(diào)校

　　Chassis system calibration

　　每行駛4萬(wàn)公里進(jìn)行四輪定位參數(shù)校準(zhǔn)，重點(diǎn)調(diào)整前束角與外傾角。對(duì)配備空氣懸架的車型，需使用專用診斷儀進(jìn)行高度傳感器校準(zhǔn)，誤差控制在±1mm以內(nèi)。

　　Perform four-wheel alignment parameter calibration every 40000 kilometers, with a focus on adjusting the toe angle and camber angle. For vehicles equipped with air suspension, a dedicated diagnostic instrument is required for height sensor calibration, with an error controlled within ± 1mm.

　　三、電子系統(tǒng)的深度檢測(cè)

　　3、 Deep detection of electronic systems

　　現(xiàn)代奔馳車型搭載30余個(gè)電子控制單元，需定期進(jìn)行軟件更新與硬件檢測(cè)：

　　Modern Mercedes Benz models are equipped with over 30 electronic control units, which require regular software updates and hardware testing

　　診斷儀全掃描

　　五、特殊工況的應(yīng)對(duì)策略

　　5、 Response strategies for special working conditions

　　針對(duì)不同使用場(chǎng)景，制定專項(xiàng)養(yǎng)護(hù)方案：

　　Develop specialized maintenance plans for different usage scenarios:

　　高溫環(huán)境養(yǎng)護(hù)

　　High temperature environment maintenance

　　在環(huán)境溫度>35℃時(shí)，需加強(qiáng)冷卻系統(tǒng)檢測(cè)。每2萬(wàn)公里更換冷卻液，確保冰點(diǎn)<-35℃，沸點(diǎn)>135℃，防止發(fā)動(dòng)機(jī)開鍋。

　　When the ambient temperature is above 35 ℃, it is necessary to strengthen the detection of the cooling system. Replace the coolant every 20000 kilometers to ensure that the freezing point is below -35 ℃ and the boiling point is above 135 ℃, in order to prevent the engine from boiling.

　　低溫環(huán)境啟動(dòng)

　　Low temperature environment startup

　　在環(huán)境溫度<5℃時(shí)，需使用電加熱機(jī)油濾清器，預(yù)熱機(jī)油至40℃以上再啟動(dòng)，降低冷啟動(dòng)磨損60%。對(duì)柴油車型，需安裝進(jìn)氣預(yù)熱格柵。

　　When the ambient temperature is below 5 ℃, an electrically heated oil filter should be used to preheat the oil to above 40 ℃ before starting, reducing cold start wear by 60%. For diesel models, it is necessary to install an intake preheating grille.

　　涉水行駛處理

　　Handling of driving through water

　　通過積水路段后，需立即檢查空氣濾清器濕度。如發(fā)現(xiàn)進(jìn)水，需更換濾清器并對(duì)發(fā)動(dòng)機(jī)艙進(jìn)行干燥處理，防止電子模塊腐蝕。

　　After passing through the flooded section, it is necessary to immediately check the humidity of the air filter. If water is found to have entered, the filter should be replaced and the engine compartment should be dried to prevent corrosion of the electronic module.

　　六、養(yǎng)護(hù)質(zhì)量的溯源管理

　　6、 Traceability management of maintenance quality

　　建立數(shù)字化養(yǎng)護(hù)檔案，實(shí)現(xiàn)全生命周期追溯：

　　Establish digital maintenance records to achieve full lifecycle traceability:

　　電子健康檔案

　　Electronic health records

　　通過Mercedes me APP，可查看歷史保養(yǎng)記錄、維修診斷報(bào)告、零件溯源信息。對(duì)更換的每個(gè)零件，可掃描二維碼查詢生產(chǎn)批次與質(zhì)檢報(bào)告。

　　Through the Mercedes me app, users can view historical maintenance records, repair diagnostic reports, and parts traceability information. For each replaced part, the production batch and quality inspection report can be queried by scanning the QR code.

　　養(yǎng)護(hù)過程監(jiān)控

　　Monitoring of maintenance process

　　在授權(quán)服務(wù)中心，關(guān)鍵保養(yǎng)工序需通過視頻記錄存檔。如機(jī)油加注量、螺栓緊固扭矩等參數(shù)，可隨時(shí)調(diào)取復(fù)查。

　　At the authorized service center, critical maintenance procedures need to be recorded and archived through video. Parameters such as oil filling amount and bolt tightening torque can be retrieved and rechecked at any time.

　　質(zhì)量反饋機(jī)制

　　Quality feedback mechanism

　　保養(yǎng)后72小時(shí)內(nèi)，客服中心進(jìn)行滿意度回訪。如發(fā)現(xiàn)養(yǎng)護(hù)質(zhì)量問題，啟動(dòng)快速響應(yīng)流程，48小時(shí)內(nèi)完成整改并復(fù)檢。
