沃爾沃全系車型四萬公里的保養項目包括：機油、機濾、空濾、空調濾、汽濾、火花塞、剎車油。清洗節氣門。

　　The maintenance items for 40000 kilometers of all Volvo models include: engine oil, oil filter, air filter, air conditioning filter, steam filter, spark plug, and brake oil. Clean the throttle valve.

　　1、更換機油和機濾。

　　1. Replace the oil and oil filter.

　　常規保養就是經常說的小保（機油 機濾）一般是8000-10000公里做一次或半年做一次。建議：如果車的公里數10萬以上或更高公里數，建議6000-8000公里做一次常規保養。

　　Regular maintenance is commonly referred to as minor maintenance (oil filter), which is usually done every 8000 to 10000 kilometers or every six months. Suggestion: If the mileage of the car is over 100000 kilometers or higher, it is recommended to perform routine maintenance between 6000 and 8000 kilometers.

　　2、更換空濾。

　　2. Replace the air filter.

　　空濾就是空氣濾清器，它會過濾掉進入發動機內的灰塵，類似發動機的口罩。空濾材料為濾紙，為了增加空氣的通過面，大多數濾芯加工時會做成有很多細小的褶皺，如果過濾不佳會增加油耗，更糟糕的是對渦輪增壓器有一定損傷。建議每兩萬公里更換一個。

　　An air filter is an air filter that filters out dust that enters the engine, similar to an engine mask. The air filter material is filter paper. In order to increase the airflow, most filter elements are processed with many small wrinkles. If the filtration is not good, it will increase fuel consumption, and worse, it will cause certain damage to the turbocharger. Suggest replacing it every 20000 kilometers.

　　3、跟換空調格。

　　3. Replace the air conditioning unit.

　　空調格一般都是含活性炭材料，它可以吸收空氣中的有害物質，主要過濾凈化車內空氣，尤其在夏天和冬天開空調車內味道重，建議深度清洗空調系統和更換空調格（兩者缺一不可），建議每兩萬公里更換或季節交替時更換一個。

　　Air conditioning grids are generally made of activated carbon materials, which can absorb harmful substances in the air and mainly filter and purify the air inside the car. Especially in summer and winter, when air conditioning is turned on, the smell inside the car is strong. It is recommended to thoroughly clean the air conditioning system and replace the air conditioning grid (both are indispensable). It is recommended to replace it every 20000 kilometers or at seasonal intervals.

　　4、更換汽濾。

　　4. Replace the steam filter.

　　汽濾主要是起過濾汽油的作用，一般開車時有過油不順感覺，很可能就是汽濾的油孔被油泥堵塞。沃爾沃廠家一般建議每2萬公里更換一個。

　　The main function of the car filter is to filter gasoline. Generally, when driving, there is a feeling of poor oil flow, which is likely due to the oil hole of the car filter being blocked by sludge. Volvo manufacturers generally recommend replacing one every 20000 kilometers.

　　5、更換火花塞。

　　5. Replace the spark plug.

　　沃爾沃全系車型大多數是用的鉑金火花塞。鉑金火花塞的特點就是使用時間長，耐用性高，如果出現跳火或漏電現象要及時更換，火花塞建議每四萬公里更換一次。

　　Most Volvo models across the range use platinum spark plugs. The characteristics of platinum spark plugs are long service life and high durability. If there is a spark or leakage phenomenon, it should be replaced in a timely manner. It is recommended to replace spark plugs every 40000 kilometers.

　　6、更換剎車油。

　　6. Replace the brake fluid.

　　剎車油對剎車系統至關重要，沃爾沃使用的是DOT4標號的剎車油。剎車油使用時間過長了會產生一定的含水量，剎車高溫會使水分蒸發汽化，會讓剎車油管形成氣阻，導致剎車遲鈍、滯后會使剎車距離變長甚至失靈等情況。建議沃友使用沃爾沃廠家指定的原廠原裝剎車油。廠家指導要求剎車油一般兩年或4萬公里更換一次。

　　Brake fluid is crucial to the braking system, and Volvo uses DOT4 grade brake fluid. Excessive use of brake fluid can result in a certain amount of water content. High temperatures in the brakes can cause the water to evaporate and vaporize, leading to air resistance in the brake oil pipes. This can result in brake sluggishness, lag, longer braking distances, and even failure. I suggest that you use the original brake fluid specified by the Volvo manufacturer. The manufacturer's guidance requires brake fluid to be replaced every two years or 40000 kilometers.

　　7、清洗節氣門。

　　7. Clean the throttle valve.

　　清洗節氣門是很有必要的，因為沒有被空濾過濾掉的灰塵都粘附著在節氣門周邊，遇到油氣就會形成油泥。時間長了就會變成厚厚的積碳。建議節氣門一般兩萬公里清洗一次。

　　It is necessary to clean the throttle valve because the dust that has not been filtered out by the air filter adheres to the periphery of the throttle valve, and when it encounters oil and gas, it will form sludge. Over time, it will turn into thick carbon deposits. It is recommended to clean the throttle valve every 20000 kilometers.
