冬季是再次使用暖空气的季节。加热系统长时间停机会出现故障，所以首先要检查是否有热风，风扇运转是否有异响，风道是否通畅。有时暖风水管中的防冻液长时间不流动，冷凝堵塞循环管道。虽然不影响行车，但是维护起来很麻烦。如有问题，必须及时到4S店维修。
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.
需要检查防冻液。防冻液的用量必须适当。维修技师建议每两年更换一次防冻液，但混合（尤其是夏季加水）的防冻液必须每年更换一次。注意不同品牌和型号的产品不能混用，其次是机油。冬季对汽车油的润滑要求更高。如果在夏季使用机油，则必须更换。应更换以确保发动机平稳启动。
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.
虽然冬季玻璃清洗的使用会明显减少，但也不容忽视。有些人在其他消耗量大的季节用清水和清水代替，但这些替代品在冬天经常结冰，所以不能在冬天使用。在零摄氏度以下的环境下，应更换防冻剂冬季玻璃水，或者更简单的说，在玻璃水中加入适量的酒精，即可达到降低冰点和防冻的目的。
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，为宝马汽车全身做个“美容”。由于天气寒冷，入冬后刷车的次数会减少，所以在初冬打蜡是保养车漆的好方法。此外，打蜡的车身不易受潮，冬天也不易凝结成冰。
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.
电池怕低温，低温环境下的电池容量比常温下低很多。因此，在寒冷季节到来之前，应补充电池的电解液，并调整电解液的比重。同时，清洁蓄电池的接线柱，并涂上专用油脂进行保护，以确保可靠启动，延长蓄电池寿命。如果车辆在露天或冷藏库中停放数周，则应将电池取出并存放在较温暖的房间中，以防止因冻结而损坏电池。
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.
冬季轮胎橡胶变得更硬且相对脆，并且摩擦系数降低。胎压不宜过高，但也不宜过低。车外温度低，轮胎气压过低。严重的软胎会加速老化。冬季要经常清理胎纹中的夹杂物，尽量避免使用多次修复过的轮胎，更换磨损较大、不同品牌、不同花纹的轮胎。轮胎内外的磨损情况大不相同。为确保安全，减少磨损，应定期更换轮胎。
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.
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.
