When washing the car in the hot sun, the convex lens effect formed by water droplets will cause local high temperature on the upper layer of the car paint. After a long time, the car paint will lose its luster. If waxing at this time, it is also easy to cause uneven body color. Therefore, the car washing and waxing are carried out under the condition of shelter. If not, Mercedes Benz maintenance is recommended to be carried out in the morning and evening on cloudy or sunny days. The owner should understand the following correct maintenance knowledge.

進口輪胎--不適用

Imported tyres - not applicable

有些人買輪胎特別喜歡強調“進口”。國外推的新款輪胎對國內的用戶來說有一個致命的缺陷就是不適用。歐洲平整的路面與北京二環、三環的路況有較大區別，適合歐洲路況的輪胎在北京就難有上佳表現，特別是胎側的耐沖擊力方面顯然有些水土不服，就如同穿意大利皮鞋走石子路一般，胎側起包在所難免。一些國外品牌的輪胎在國內合資生產后，都根據國內道路狀況在輪胎側面增加了一層簾子布，從而大大增強了胎側的抗沖擊力，合資生產的輪胎從性能上講完全能夠替代進口貨。

Some people like to emphasize "import" when buying tires. The new tires launched abroad have a fatal defect for domestic users, that is, they are not applicable. The flat road surface in Europe is quite different from the road conditions of the second ring road and the Third Ring Road in Beijing. It is difficult for tires suitable for European road conditions to have a good performance in Beijing. In particular, the impact resistance of the sidewall is obviously acclimatized. Just like wearing Italian leather shoes on gravel roads, it is inevitable to pack the sidewall. After the domestic joint venture production of some foreign brand tires, a layer of cord fabric is added on the tire side according to the domestic road conditions, which greatly enhances the impact resistance of the sidewall. The tires produced by the joint venture can completely replace the imported goods in terms of performance.

新蓄電池不充電--縮短壽命

The new battery is not charged -- shortening the service life

蓄電池的充電稱為初次充電，初次充電對蓄電池的使用壽命有的影響。若不充電，即加“水”直接使用，蓄電池的容量不高，壽命將縮短；若直接充電，也會縮短壽命。通常蓄電池的初次充電是在加注完電解液后，用小電流充電大約1小時左右即可安裝使用。

The charging of the battery is called the initial charging, which has an impact on the service life of the battery. If you do not charge, that is, add "water" for direct use, the capacity of the battery is not high and the service life will be shortened; If directly charged, it will also shorten the service life. Generally, the initial charging of the battery is after filling the electrolyte, and it can be installed and used after charging with a small current for about 1 hour.

車內設備隨意加--影響行車安全

Random addition of equipment in the vehicle -- affecting driving safety

南城奔馳改裝廠表示私人轎車是車主移動的家，追求乘用舒適和豪華無可厚非，但一些車主自己動手在車內加裝各種設備，這種改裝，如果處理不妥當，對汽車性能及操縱的方便和可靠性往往帶來不利影響，易留下后遺癥或影響行車安全。

Nancheng Benz Refitting Factory said that private cars are the mobile home of car owners, and it is understandable to pursue riding comfort and luxury. However, some car owners install various equipment in the car by themselves. If this refitting is not handled properly, it often has an adverse impact on the performance, convenience and reliability of vehicle operation, and is easy to leave sequelae or affect driving safety.

水箱“開鍋”速加水--氣缸開裂

Water tank "boiling" quick water filling - cylinder cracking

天氣熱的時候，有的司機一看見水箱出現“開鍋”現象，就擔心發動機溫度再升高，立即熄火加水。這種做法是錯誤的，它極可能造成氣缸蓋因為突然受冷而出現開裂現象。如果碰見水箱“開鍋”，一般正確的方法是：立即停車，讓發動機保持怠速空轉繼續散熱；同時打開發動機罩，提高散熱速度。待冷卻水溫度降低后，再將發動機熄火。此時如果冷卻水數量不足時，應緩緩添加，以防氣缸蓋因驟然受冷而出現開裂。

When the weather is hot, as soon as some drivers see the "boiling" phenomenon in the water tank, they are worried that the engine temperature will rise again, and immediately turn off the engine and add water. This practice is wrong. It is very likely to cause the cylinder head to crack due to sudden cold. If the water tank "boils", the general correct method is to stop immediately and let the engine idle to continue heat dissipation; At the same time, open the hood to improve the heat dissipation speed. Turn off the engine after the cooling water temperature decreases. At this time, if the amount of cooling water is insufficient, add it slowly to prevent the cylinder head from cracking due to sudden cooling.

長期不用車或短途用車--機件受損

Vehicles not used for a long time or short distance vehicles -- parts damaged

有的人雖然成為了有車族，但平時“不舍得”開車，寮步奔馳汽修廠認為只有放假時才開車出去玩，其實這樣的用車方式是很傷車的。引擎與變速箱等傳動機件表面會因常處于與空氣直接接觸的狀態而生銹，電瓶也會因為長期的自然放電影響到使用壽命。

Although some people have become car owners, they are usually "unwilling" to drive. Liaobu Mercedes Benz garage believes that they only drive out during holidays. In fact, this way of driving is very harmful to the car. The surface of transmission parts such as engine and gearbox will rust due to direct contact with air, and the service life of battery will be affected by long-term natural discharge.

好的方法是每隔幾天就跑一次車，跑個三四十分鐘。另外，總是短途用車也會傷車，車隨時在動但都開不遠，是傷車的重要原因。車上機件在發動機啟動至穩定階段之間磨損嚴重，發動一次車電瓶所消耗的電力也大約要行駛20分鐘才能補足，這樣的用車習慣很容易使車子提早出毛病。

A good way is to run the car every few days for 30 or 40 minutes. In addition, always using short distance vehicles will also hurt the car. The car is moving at any time, but it can't drive far, which is an important reason for hurting the car. The engine parts on the car are seriously worn between the engine start and the stable stage. The power consumed by the battery to start the car takes about 20 minutes to make up. Such a habit of using the car is easy to make the car go wrong early.

洗車像洗澡--害空調

Washing the car is like taking a bath -- damaging the air conditioner

遇上天氣氣溫升高，灰塵加大，車身容易臟，車主洗車的頻率也開始上升，很多車主在洗車時也希望像給自己洗澡一樣弄得徹底。但這里要注意的是，一定要保持汽車空調外表的干爽，如果汽車空調不小心被弄濕，會影響到汽車空調的壽命。

In case of weather, the temperature rises, the dust increases, and the car body is easy to get dirty. The frequency of car owners' car washing also begins to rise. Many car owners hope to wash the car as thoroughly as they bathe themselves. However, it should be noted that the appearance of the car air conditioner must be kept dry. If the car air conditioner is accidentally wet, it will affect the service life of the car air conditioner.
