所謂三分開七分養，汽車的養護實際上是一個很重要的過程，所以各位車主要認真對待，那么您知道汽車養護的“四保”具體內容是什么嗎？在此展開講講。
The so-called three separate seven, car maintenance is actually a very important process, so you car mainly seriously, then you know the car maintenance of the “four” specific content is what? Let me expand on that.
1保
又稱首保，首保是免費的，不管去哪個相同品牌的4S店都可以做。首保一般情況下會更換下機油機濾，同時對各個部位螺絲進行簡單檢查，以及對底盤、燈光、輪胎進行簡單檢查，這就是首保的一些內容。
1 keep
Also known as the first warranty, the first warranty is free, no matter which 4S shop of the same brand can do. Under normal circumstances, the first warranty will replace the oil machine filter, and at the same time, a simple check of the screws in each part, as well as a simple check of the chassis, lights, tires, this is the first warranty some of the content.
2保
與保養間隔5000公里或6個月后，如果更換的是全合成機油，公里數及時間上可以延后。在2保時，車輛的性能我們已經熟悉，車輛的各個功能及性能也穩定下來。
在2保時涉及到的保養項目并不復雜，是機油機濾、空濾空調濾的更換，同時對車輛各個系統進行檢查，比如胎壓、燈光、剎車轉向、發動機艙各個油水的檢查。
2 bao
With the first maintenance interval of 5000 km or 6 months, if the replacement of synthetic oil, the mileage and time can be delayed. At the time of 2 warranty, we have been familiar with the performance of the vehicle, and the various functions and performance of the vehicle have been stabilized.
The maintenance items involved in the 2 warranty are not complicated, focusing on the replacement of oil machine filter, air filter and air conditioning filter, and checking each system of the vehicle, such as tire pressure, lighting, brake steering, engine room oil and water inspection.
3保
一般情況下公里數在1.5萬公里左右，3保與2保做的內容相同，只需要常規保養即可，機油機濾的更換，胎壓、燈光、底盤的檢查，如果車主感覺車輛有問題或者小毛病以及異響等可以提出來，讓維修技師檢查下。
需要注意這個時候車主開車會有一種盲目自信，認為自己的駕駛技術已經非常好，對車輛已經非常熟悉，在開車時不會像剛開車時那么謹慎，此時開車在路上反而會更危險，一定要時刻謹記安全駕駛，不要路怒也不要激烈駕駛。
3 keep
Under normal circumstances, the mileage is about 15,000 kilometers, 3 and 2 do the same content, only need routine maintenance, oil filter replacement, tire pressure, light, chassis inspection, if the owner feels the vehicle has problems or small problems and abnormal sound can be put forward, let the maintenance technician check.
It should be noted that at this time, the owner of the car will have a kind of blind confidence when driving, thinking that his driving skills have been very good, and he is very familiar with the vehicle. When driving, he will not be as cautious as when he just started driving. Driving on the road at this time will be more dangerous.
4保
若按時間節點去算，車已經開了兩年，此時車已經不是新車，車主駕駛技術已經相對成熟穩定，同時對于車輛保養的一些知識也更加了解。
濟南沃爾沃汽車養護人員日認為，對于4保需要做的內容還是很簡單，機油、機濾、空濾、空調濾的更換，以及燃油濾芯的更換，檢查下防凍液、剎車油、變速箱油的品質、檢查下輪胎磨損程度、剎車片磨損程度等一些常規的檢查。
4 keep
According to the time node, the car has been driven for two years. At this time, the car is no longer a new car, and the driver has relatively mature and stable driving skills, and has a better understanding of some knowledge of vehicle maintenance.
Jinan Volvo car maintenance personnel, think for 4 cover the content of the need to do is very simple, oil filter, air filter, air conditioning, machine filter replacement, as well as the fuel filter replacement, check antifreeze, brake fluid, the quality of the transmission oil, check tyre wear and brake pads wear degree, etc. Some routine check.
In fact, “four guarantee” is routine maintenance, so it takes some energy to maintain the car to be safe on the road, maintain the car to ensure the safety of themselves and others, more content to the website www.nanofluidizer.com.
