冬季是再次使用暖空氣的季節(jié)。加熱系統(tǒng)長時(shí)間停機(jī)會(huì)出現(xiàn)故障，所以首先要檢查是否有熱風(fēng)，風(fēng)扇運(yùn)轉(zhuǎn)是否有異響，風(fēng)道是否通暢。有時(shí)暖風(fēng)水管中的防凍液長時(shí)間不流動(dòng)，冷凝堵塞循環(huán)管道。雖然不影響行車，但是維護(hù)起來很麻煩。如有問題，必須及時(shí)到4S店維修。

Winter is the season when warm air is used again. If the heating system is shut down for a long time, it will fail. Therefore, first of all, check whether there is hot air, whether the fan makes abnormal noise and whether the air duct is smooth. Sometimes the antifreeze in the heating water pipe does not flow for a long time, and the circulating pipe is blocked by condensation. Although it does not affect the driving, it is troublesome to maintain. If there is a problem, it must be repaired in the 4S store in time.

需要檢查防凍液。防凍液的用量必須適當(dāng)。維修技師建議每兩年更換一次防凍液，但混合（尤其是夏季加水）的防凍液必須每年更換一次。注意不同品牌和型號的產(chǎn)品不能混用，其次是機(jī)油。冬季對汽車油的潤滑要求更高。如果在夏季使用機(jī)油，則必須更換。應(yīng)更換以確保發(fā)動(dòng)機(jī)平穩(wěn)啟動(dòng)。

Antifreeze needs to be checked. The amount of antifreeze must be appropriate. The service technician recommends that the antifreeze be replaced every two years, but the antifreeze mixed (especially in summer) must be replaced every year. Note that products of different brands and models should not be mixed, followed by engine oil. In winter, the lubrication requirements for automobile oil are higher. If the oil is used in summer, it must be replaced. It should be replaced to ensure that the engine starts smoothly.

雖然冬季玻璃清洗的使用會(huì)明顯減少，但也不容忽視。有些人在其他消耗量大的季節(jié)用清水和清水代替，但這些替代品在冬天經(jīng)常結(jié)冰，所以不能在冬天使用。在零攝氏度以下的環(huán)境下，應(yīng)更換防凍劑冬季玻璃水，或者更簡單的說，在玻璃水中加入適量的酒精，即可達(dá)到降低冰點(diǎn)和防凍的目的。

Although the use of glass cleaning in winter will be significantly reduced, it can not be ignored. Some people use clean water and clean water in other seasons with high consumption, but these substitutes often freeze in winter, so they cannot be used in winter. In the environment below zero degrees Celsius, the antifreeze should be replaced with winter glass water, or more simply, an appropriate amount of alcohol should be added to the glass water to achieve the purpose of reducing the freezing point and antifreezing.

入冬前，為寶馬汽車全身做個(gè)“美容”。由于天氣寒冷，入冬后刷車的次數(shù)會(huì)減少，所以在初冬打蠟是保養(yǎng)車漆的好方法。此外，打蠟的車身不易受潮，冬天也不易凝結(jié)成冰。

Before winter, do a "hairdressing" for BMW. Due to the cold weather, the number of car painting will be reduced after winter, so waxing in early winter is a good way to maintain car paint. In addition, the waxed car body is not easily affected by moisture, and it is not easy to condense into ice in winter.

電池怕低溫，低溫環(huán)境下的電池容量比常溫下低很多。因此，在寒冷季節(jié)到來之前，應(yīng)補(bǔ)充電池的電解液，并調(diào)整電解液的比重。同時(shí)，清潔蓄電池的接線柱，并涂上專用油脂進(jìn)行保護(hù)，以確?？煽繂?dòng)，延長蓄電池壽命。如果車輛在露天或冷藏庫中停放數(shù)周，則應(yīng)將電池取出并存放在較溫暖的房間中，以防止因凍結(jié)而損壞電池。

The battery is afraid of low temperature. The battery capacity under low temperature environment is much lower than that under normal temperature. Therefore, before the cold season, the electrolyte of the battery should be supplemented and the specific gravity of the electrolyte should be adjusted. At the same time, clean the terminals of the battery and apply special grease for protection to ensure reliable startup and prolong the service life of the battery. If the vehicle is parked in the open air or cold storage for several weeks, the battery shall be taken out and stored in a warmer room to prevent damage to the battery due to freezing.

冬季輪胎橡膠變得更硬且相對脆，并且摩擦系數(shù)降低。胎壓不宜過高，但也不宜過低。車外溫度低，輪胎氣壓過低。嚴(yán)重的軟胎會(huì)加速老化。冬季要經(jīng)常清理胎紋中的夾雜物，盡量避免使用多次修復(fù)過的輪胎，更換磨損較大、不同品牌、不同花紋的輪胎。輪胎內(nèi)外的磨損情況大不相同。為確保安全，減少磨損，應(yīng)定期更換輪胎。

In winter, the tire rubber becomes harder and relatively brittle, and the coefficient of friction decreases. The tire pressure should not be too high, but not too low. The outside temperature is low, and the tire pressure is too low. Severe soft tires will accelerate aging. In winter, the inclusions in the tread shall be cleaned frequently. Try to avoid using the repaired tires for many times, and replace the tires with large wear, different brands and different patterns. The wear conditions inside and outside the tire are very different. To ensure safety and reduce wear, tyres should be replaced regularly.

濟(jì)南寶馬汽車專修人員提醒您，冬天可以換高檔汽油。由于冬季汽車環(huán)境溫度較低，使用高標(biāo)號汽油燃點(diǎn)更高，點(diǎn)火能力更強(qiáng)。更多關(guān)于汽車維護(hù)或者養(yǎng)護(hù)的知識了解，您可以關(guān)注我們網(wǎng)站www.nhakhoathuduc.net獲取到！

Jinan BMW special repair personnel remind you that you can change to high-grade gasoline in winter. Due to the low ambient temperature of vehicles in winter, the ignition point and ignition ability of high-grade gasoline are higher.
