  7. Don't be negligent! The...

[YesAuto Use Car Collection] It’s raining heavily in Beijing again. I think many of my friends have received various WeChat and text messages forwarded by car dealers and friends: the start-stop function is turned off in heavy rain. In fact, this issue has been controversial since the popularization of the automatic stop function. Should it be turned off?

1. Misunderstanding: It doesn't matter just flooding the exhaust pipe

Many people are afraid to use the start-stop function because they are afraid that someone will flood the exhaust pipe and pour water back into the engine and cause losses. In fact, friends who have this idea can rest assured that the exhaust pipe is underwater, whether it is driving or idling. There is no problem if the engine is turned off and re-ignited. Whether the engine is damaged depends on whether the water level exceeds the position of the engine's air intake, which is the most deadly. “do you know? Wading and flameout has nothing to do with water in the exhaust pipe” The video below shows an SUV draining water just after wading.

2. The battery can also work if it is soaked

First of all, those who gave this suggestion were true friends! Because the engine is wading in the water, if the water surface exceeds the position of the air intake, the engine will be submerged due to the ingress of water, but the battery can still work at this time, if you see a lot of soaking in the water The car's lights are still on?

3. It is also possible to start and stop after flooding!

When the battery works, some electrical appliances can work unless it has been short-circuited, so the start-stop system will still give you a “surprise” when the engine is flooded. For example, a driver is in the process of passing water on the road. I stepped on the brake and the water just passed the air intake. At this time, when the brake is lifted, the engine restarts, which is equivalent to ignition in the water. You may say that the ignition will not fire. The result is the same for the ignition, but for the loss It's different.

4. The “secondary ignition” function of being started and stopped is also costly

Everyone has heard of the term “secondary ignition”, which means that the vehicle is submerged under water, and then turn the key to ignite again under water. If you are in the wading insurance, no ignition and secondary ignition The corresponding is that claims can be settled and not necessarily claims can be settled. PS: The wading insurance only cares about the losses caused by the engine flooding, regardless of other losses of the vehicle. “Click here for details”.

Therefore, please include all kinds of SMS and WeChat suggestions. In the case of heavy rain or may pass through the watery road, please turn off the start-stop system, and every time, because this function is generally turned on by default after the vehicle is started.

But having said that, the state of wading + water level exceeding the air inlet + start and stop work at the same time is indeed too coincidental. The probability of occurrence is very small, but it is likely to happen, so everyone does not need to panic. Let's do it. It is possible to reduce unnecessary losses and just close the start and stop, without being overly entangled.

If the car is still stranded in the end, please do not stay in the car, evacuate to a safe area as soon as possible, call the police and wait for rescue. It is also recommended that you pay attention to the recent weather. If there is a lot of precipitation the next day, arrange a reasonable trip to avoid unnecessary losses and hurt.
