The hot weather is coming, and this safe driving cheat is collected by car owners.

First, pay attention to the high water temperature to prevent "boiling"

Pay attention to the water thermometer of the car in hot weather. This water thermometer is on our dashboard, which has two display modes, one is digital water thermometer, and the other is water temperature alarm lamp. The normal temperature range of water thermometer is 80- 100℃. Generally, when we drive, the water temperature is 90℃.

Once the water temperature meter exceeds 100℃, the water temperature alarm light will light up. At this time, you should immediately drive to the shade and let the car stop to have a rest to prevent the phenomenon of "boiling". You know, "boiling pot" is very harmful to cars. If the water temperature is kept at a high temperature, the cylinder head and cylinder will be deformed or even damaged, and the piston seal is not good, which is easy to cause cylinder pulling, which is immeasurable damage to the automobile engine.

Avoid "boiling the pot" if you can avoid it, and don't panic if you can. Stop immediately after "boiling", but don't turn off the engine and let the car run at idle speed. The cooling system will stop working because of flameout.

We can open the hood to let the car cool down naturally. At this time, don't open the lid of the kettle, because the coolant is easy to spray out when it is "boiling", and it will be burned if you are not careful.

Second, don't drive in slippers to cool down.

In hot weather, many people, both men and women, wear slippers. One is cool and the other is beautiful. But as a driver, it is not appropriate to wear slippers to drive. When driving with slippers, it is easy for slippers not to follow their feet when stepping on the accelerator or braking, and it is easy to cause traffic accidents if the braking time is delayed.

Third, don't drive with dark sunglasses.

In the scorching sun, many people wear sunglasses to avoid direct sunlight. The driver thinks it's ok to wear sunglasses, but you can't wear dark sunglasses. A light polarizer is more suitable. Because wearing dark sunglasses will delay the time that glasses will affect the transmission to the brain, it is easy to cause speed perception distortion.

Fourth, check the tire pressure regularly and pre-explode the tire.

Everyone should know the principle of thermal expansion and contraction, and the air pressure in automobile tires will also increase with the increase of temperature. Especially at high speed, the tread temperature is very high. The normal tire pressure of a car is generally between 2.3 and 2.8 bar. The tire pressure is too high, which can easily lead to a puncture. When driving at high speed, the danger of puncture is quite great, otherwise the car will be destroyed and people will die.

So I suggest you install a tire pressure monitor on your car. It would be great to buy an original car. Always check whether the tire pressure is within the normal range. If the tire pressure exceeds the normal range, stop immediately to reduce the tire temperature, thus reducing the tire pressure.

Five, to prevent automobile spontaneous combustion

High temperature in summer also easily leads to spontaneous combustion. Not only fuel cars, but also electric cars. How to prevent auto-ignition? In fact, it is very simple, as long as you pay attention to maintenance at ordinary times. Check the oil circuit and circuit of the car to see if there is oil leakage and the circuit is aging.

At the same time, do not place inflammable and explosive articles in the car. Lighters must not be put in the car, and liquid perfumes are best not put in the car, because most liquid perfumes contain alcohol. There are also some sunglasses, water bottles and other things that are easy to cause light convergence. Don't put them out of the sunlight.

The above are some safe driving skills in hot weather, and car owners must pay attention. In summer, people spend a lot of energy and sweat a lot, and it is often easy to feel sleepy when sitting down, but car owners should remember not to feel sleepy when driving and try to refresh themselves.
