1. Replace the blackened bulb as soon as possible, and check the condition of fog lamp and brake lamp. It is easy to fog and frost in winter, and the visibility is low. Whether the fog lamp and high-level brake lamp work normally is also the guarantee of driving safety in winter.
2. If the destination of self driving tour is mostly frozen area, it's best to do a "beauty" for the whole body of the car nearby. Waxing in early winter is a good way to maintain car paint. In addition, the waxed car body is not easy to get wet, and the phenomenon of condensation and ice will not easily appear in the low-temperature area in winter.
3. When driving to Hunan or further north, we should also pay attention to the problem of glass water. Although the glass cleaning agent will be significantly reduced in winter, it can not be ignored. Some people use clean water and washing water instead in other seasons with large consumption, but those substitutes often freeze in winter, so they can't be used in winter, In the environment below zero degrees Celsius in winter, the antifreeze winter glass water should be replaced, or more simply, adding an appropriate proportion of alcohol into the glass water can achieve the purpose of reducing the freezing point and antifreeze.
