Deep tire pattern makes driving more stable. Long distance driving in winter must be a great test for tires. At this time, it is very necessary to check tires before traveling. The temperature is low in winter. According to the principle of thermal expansion and cold contraction, car owners should appropriately increase the inflation pressure of tires and reduce tire wear. In general, in cold winter, the inflation pressure is 10% ~ 15% higher than the standard. At the same time, pay attention to the state of the tire to see if there are bulges and scratches, pay attention to the wear degree of the tire, and replace it in time if any problems are found.   

　　In addition, it is also necessary to pay attention to the tire pattern wear indicator block (the indicator block is on the side of the tire and is generally marked by an outward arrow). If the tire is worn to this indicator block, it means that the tire has lost the conditions for use when it is slippery in winter and can only be used as a general spare tire.   

　　I don't know how many people will read the manual carefully when buying a car. Many young car owners don't even know how to turn on and off the lights. Don't go through the manual to find out how to use it when you need to use a certain function while driving.   

　　We should carefully check whether the front and rear lights, turn signals, horns, rear-view mirrors, windows, wipers and other components work normally, and eliminate hidden dangers in advance. In addition, we should pay attention to check the vehicle air conditioning system. In such a cold day, if there is something wrong with the on-board air conditioning, can you hold the steering wheel well? Therefore, before driving, be sure to check all systems of the vehicle to ensure normal operation on the way.   

　　Vehicle emergency response method

　　1. What should I do if I suddenly turn off the engine on the way?   

　　Let's not talk about the danger. If the vehicle suddenly stalls, turn on the right turn signal in time. When there are no other vehicles on the right, stop at the emergency stop as soon as possible and try to start the engine again. If it still cannot be started, turn on the double flashing light quickly, place a warning sign 100 meters behind the vehicle, and then leave the vehicle quickly.    

　　2. What if the brake fails suddenly?   

　　If there is enough distance from the vehicle in front, you can drive the vehicle into the emergency parking belt as soon as possible on the premise of ensuring the safety of the right side. If the vehicle is in manual gear, you can also shift the gear to low gear for engine braking. After stopping the vehicle, quickly turn on the double flashing light, place a warning sign 100 meters behind the vehicle, and then leave the vehicle for rescue.   

　　3. What if the tire leaks or bursts?   

　　Be sure to keep calm after a flat tire. The driver should try his best to keep the vehicle's direction stable, hold the steering wheel tightly, avoid turning the steering wheel to correct, and do not take emergency braking at the same time. What you need to do is slowly release the accelerator and gradually control the vehicle as you slow down.
