When driving on icy and snowy roads, it is important to make judgments in advance and reserve the braking distance. The reasons for reserving braking distance and the method of starting the car in extremely cold weather are as follows: Reasons for reserving braking distance: It should be noted that the braking distance of the vehicle will be extended. Icy and snowy roads are different from normal roads, which will reduce the friction of the vehicle tires and the adhesion will also become smaller. When driving on icy and snowy roads, it is necessary to make judgments in advance and reserve the braking distance. Method of starting the car in extremely cold weather: Depress the clutch in neutral gear, do not step on the accelerator, and start the engine instantly without igniting it. Each interval should be more than 10 seconds, and at least 3 times. The purpose is to start the lubrication system. After the engine is started, keep the clutch depressed in neutral gear and warm up the car at idle speed. After 1 minute, release the clutch. If the engine does not stay on, depress the clutch for a while longer. Until the engine stays on, release the clutch and continue to warm up the car at idle speed for 1-2 minutes.
