汽车头一次保养须在汽车行驶5000公里以内或半年以内，这两个标准以先到为主。一般情况下，汽车行驶4000—5000公里之间是给比较适合做汽车保养的，就是为了新发动机的磨合期间适应各个部件适应能力，磨合期间时速达到120km以下即可。
The first maintenance of the car must be within 5000 kilometers or half a year. The two standards are based on the first come first. In general, the vehicle running between 4000-5000 kilometers is suitable for vehicle maintenance, which is to adapt to the adaptability of various components during the running in period of the new engine, and the speed can be less than 120km per hour during the running in period.

小保养要求每隔5000公里或者是半年就要进行一次。
Minor maintenance is required every 5000 kilometers or half a year.
小保养需要做什么？
What do I need to do for minor maintenance?
小保养一般是指汽车行驶一定距离后，为保障车辆性能而在厂商规定的时间或里程做的常规保养项目。主要包括更换机油和机油滤清器。
Minor maintenance generally refers to the routine maintenance items done at the time or mileage specified by the manufacturer to ensure the vehicle performance after driving a certain distance. It mainly includes changing oil and oil filter.
1、更换机油
1. Change the oil
更换机油是每次保养一定要做的项目。机油能对发动机起到润滑减磨、辅助冷却降温、密封防漏、防锈防蚀、减震缓冲等作用，不过在发动机内高温、高压的恶劣环境下，机油保质期会大幅缩短，性能大幅下降，久而久之对发动机起不到保护所用。
Changing engine oil is a must for every maintenance. The engine oil can play the role of lubrication and wear reduction, auxiliary cooling and cooling, sealing and leakage prevention, rust prevention and corrosion prevention, shock absorption and buffer for the engine. However, under the harsh environment of high temperature and high pressure in the engine, the shelf life of the engine oil will be greatly shortened and the performance will be greatly reduced, which will not protect the engine over time.
2、更换机油滤芯
2. Replace the oil filter element
更换机油滤芯是在更换机油同时进行的，机油滤芯就好比人类的“肾脏”，滤除机油中的杂物、胶质和水分，向各润滑部位输送清洁的机油，时间久了也容易出现堵塞的情况。
The replacement of engine oil filter element is carried out simultaneously with the replacement of engine oil. The engine oil filter element is like human's "kidney". It filters out the sundries, colloids and moisture in the engine oil and delivers clean engine oil to all lubricating parts. It is also easy to be blocked after a long time.
03. 大保养
03. Major maintenance
大保养的时间：
Time of major maintenance:
大保养一般的建议时间是2万公里或者是2年进行一次。
The general recommended time for major maintenance is 20000 km or once every two years.
大保养需要做什么？：
What needs to be done for major maintenance
大保养是在小保养的基础上，除了更换机油和三滤（机油滤芯、空气滤芯和空调滤芯）以外，还会增加其他保养项目，比如更换火花塞、清洗油路等等。
Major maintenance is based on minor maintenance. In addition to replacing the engine oil and three filters (engine oil filter element, air filter element and air conditioning filter element), other maintenance items will be added, such as replacing the spark plug, cleaning the oil circuit, etc.
1、更换空气滤芯
1. Replace the air filter element
空气滤芯主要是阻隔发动机在进气过程中吸入的粉尘和颗粒，如果滤芯长期不清洁就会导致发动机内吸入灰尘，造成汽缸壁非正常磨损，所以更换空气滤芯是大保养中非常必要的。
The air filter element is mainly used to block the dust and particles inhaled by the engine during air intake. If the filter element is not cleaned for a long time, it will lead to dust inhalation in the engine and abnormal wear of cylinder wall. Therefore, it is very necessary to replace the air filter element in major maintenance.
2、更换空调滤芯
2. Replace the A / C filter element
空调滤芯的作用类似空气滤芯，只不过区别是清洁干净后的空气输送到车内，也就是说对于驾乘人员的乘车环境非常重要。长时间不清洁或更换空调滤芯，不仅使汽车空调受污染，冷却系统性能降低，而且影响驾乘人员的身体安全。
The function of the air conditioning filter element is similar to that of the air filter element, except that the clean air is delivered to the vehicle, that is, it is very important for the driving environment of drivers and passengers. Not cleaning or replacing the air conditioning filter element for a long time not only pollutes the automobile air conditioner and reduces the performance of the cooling system, but also affects the physical safety of drivers and passengers.
3、更换火花塞
3. Replace the spark plug
火花塞为易损件，普通的汽车火花塞更换周期大概在30000公里左右。根据火花塞材质的不同，其更换里程也有差异：普通铜芯火花塞更换里程；3万公里；钇金火花塞更换里程：5万公里；铂金火花塞更换里程：5万公里。
Spark plugs are vulnerable parts. The replacement cycle of ordinary automobile spark plugs is about 30000 kilometers. According to the different materials of spark plugs, the replacement mileage is also different: the replacement mileage of ordinary copper core spark plugs; 30000 km; Replacement mileage of yttrium gold spark plug: 50000 km; Replacement mileage of platinum spark plug: 50000 km.
