What should I pay attention to when driving when the weather cools down?

Door switch, cooling spray, shading, closing skylight shading, opening external circulation for heat dissipation. 1. Open the passenger window, and then repeatedly open and close the driver's door to increase the mobility of the air, thus releasing the hot air inside the car. 2. Most spray ingredients are dry ice or alcohol. Shake well before use, and then spray on the car, which can achieve the purpose of rapid cooling in the car. Sunshades are very cheap, with a minimum price of several yuan. Fold it up when not in use and put it in the car after parking, so don't worry about increasing the fuel burden. If there is a skylight in the car, don't forget to close the sun visor before getting off to prevent direct sunlight. Some car owners like the leaking gap in the skylight to ventilate, but it is useless. If it rains, the water in the car will not be worth the loss. 5. Turn on the outdoor circulation, turn on the maximum air volume, and open all windows and skylights at the same time. Get on the bus after about 1-2 minutes.
