The movie "the wandering earth" tells us "there are millions of roads and the first safety". In order to ensure the safety of driving in rainy days, the first task is not to improve various driving skills or learn experience, but not to fight unprepared battles.

There is an old saying in China: "is it a blessing or a disaster, it is a disaster to hide from". Many times, even if we know that the weather is not good, the planned schedule can not be changed, and we can only set out hard.

But that doesn't mean we have nothing to do. For example, in recent years, many e-commerce platforms began to sell the products called rain enemy, which is a good weapon for us to prepare in advance.

When driving school, the coach will tell us "go sand fast, slow over water", the latter three words are the core of wading in rainy days, but not comprehensive.

If it is confirmed that it can pass, the "slow over water" formula mentioned above should be applied. The core point of attention is not only slow, but also observation of water level. Because of the threat of water to cars, it can be classified as follows:

1. Serious damage: that is, the water level exceeds the height of the air inlet, the engine will almost certainly be damaged and "put the pick" immediately!

2. Serious damage may occur: when the water level exceeds the exhaust position, serious damage may also be caused in case of improper operation.

3. Slight damage may occur: when the water level is not over the chassis, but obviously lower than the exhaust position, there is a probability of damaging the driving mechanism or causing "chronic problems". After all, the corrosion of chassis structure parts such as rubber sleeve is also not acceptable.

The summary is to avoid entering the pool where the water level is higher than the lower side as possible. If it is not necessary to walk, the air inlet height of the vehicle shall be taken as the reference standard and the operation shall be cautious.

In addition, more and more new cars are equipped with the automatic engine start and stop function today. We need to turn off the function before wading. This is because if the vehicle is stopped by the driver during driving, the automatic start and stop system will think that the vehicle is stopped in a short time and the engine will be extinguished automatically.

In short, no matter which situation causes the engine to shut down, it is strictly forbidden to start the engine directly after flameout. First, it is not difficult to check whether the intake system of the engine is in water, and the method is not too difficult, that is, check whether the air filter is overflowed by water.

If it is wet or water traces are found in the intake manifold, there is a possibility of water intake. Although the engine is not necessarily damaged, we suggest you do not start the engine at this time and find the trailer rescue at ease.
