After the Spring Equinox, the Qingming Festival is getting closer and closer. Most of the poems related to Qingming Festival are related to rain, such as the poems "Rain pours during Qingming Festival", "Rain comes from the spring equinox to Qingming", "Shanjia is most afraid of Qingming rain"... It can be seen that there is no shortage of rain in this season. The southern region where the car buyer is located is frequently disturbed by strong convective weather, and yellow warning signals for thunderstorms and strong winds have been hung in many places in Guangdong.
After several rounds of thunderstorms, the roads in many cities in Guangdong have become a "swamp", and many vehicles are like "boats in the water", which is really a worry for the driver friends. In fact, "flooded streets" occur across the country every rainy season. When encountering water-related roads, how to pass smoothly and safely is an issue that many car owners need to pay attention to.
Before wading in water, you should stop and observe first
On rainy days, if there is water on the road, it will often cover up the potholes on the road. The dangers of the intake and exhaust pipes, the tires may also be punctured by foreign objects in the pit, or even fall into the sewer where the manhole cover is missing. Therefore, when car owners pass by roads with water overflowing such as stagnant water or tunnels, they must stop and observe the road conditions.
First of all, we need to have a preliminary understanding of the wading section ahead and determine the approximate depth of the water. The simplest way is that the water depth cannot exceed the height of the exhaust pipe. If it exceeds, it is recommended not to do so. "Test the risk with a car"; secondly, we also need to pay attention to whether there is mud or other obstacles under the water to prevent us from being injured while driving through the water. Of course, if a car similar to your own model passes safely, your own car can pass boldly.
Before you start driving, it is best to turn off the automatic start-stop function of the car. Otherwise, if you suddenly stop on a wading section to judge the road conditions ahead, the start-stop function will be activated and the engine will stall. When the water level is just below the air inlet, as long as you step on the accelerator or release the brake, or even move the steering wheel, the engine will restart, and water will be sucked into the cylinder through the air inlet, causing damage.
When wading? You should pay more attention to skills
If you are ready to walk in the water, don’t think about rushing forward like sailing a boat. You must follow the "walk quickly through the sand and walk slowly" "Water" principle, because on roads with relatively deep water, if the vehicle speed is too fast, the water waves rolled up will be pushed into the engine compartment, enter the air filter and cause it to become blocked, etc., causing unnecessary damage to the vehicle. The correct way to wade through water: slow down the vehicle speed, then switch to a low gear, lightly step on the accelerator without letting go, and pass through the standing water at a steady and slow speed (less than 20km/h).
When driving in stagnant water, do not step on the brake pedal or turn the steering wheel sharply, because the grip of the wheels will decrease sharply as the vehicle speed increases. If you operate too hard, "flooding" will easily occur. slip". When driving on rainy days, use a "point brake" method to depress the brake pedal, and apply the brake pedal continuously to make the braking force output smooth and even to avoid wheel locking. It should also be noted that when wading in water, try not to use electronic equipment such as air conditioners, because the electronic fan will rotate when the air conditioner is turned on, which may stir up water and flow into the engine compartment.
If your car is unfortunately submerged in floods, you need to stay calm and turn off the ignition immediately, and report the risk to the insurance company. If possible, you can push the car to a safe place with little water accumulation. If it cannot be pushed, contact rescuers directly. Do not try to start the engine again, as this will cause great damage to the engine.
If the car has overflowed the threshold, do not open the door and get out of the car, otherwise water will immediately enter the car, causing damage to the electrical appliances in the car. You can ask the surrounding people to help push the car to a shallow water area before considering again. Open the door and get off. If the rain keeps falling and the water continues to deepen, consider escaping the scene as soon as possible, with safety first.
After wading? Check carefully to develop good habits
After wading, we will also check the vehicle in several aspects.
First of all, after leaving the wading section, you have to drive at a low speed for a certain distance. During this period, remember to apply the brakes a few times, so that the friction between the brake pads and the brake disc can evaporate the accumulated water attached to them. Let it return to optimal braking performance as quickly as possible. Secondly, you should also check the chassis to see if there are various floating grass, ropes, and plastic bags rolled into the vehicle transmission shaft. You can also tap the engine floor to determine whether there are any debris. If these debris are allowed to hide in the car, these substances will spontaneously ignite when they are dry.
In addition, you should also check whether the bumpers, wheels, etc. of your car have been damaged while driving through water. After all, we cannot see obstacles in the water. If you are still worried about the hidden dangers of the vehicle, , then it is recommended to go to the 4S store for testing as soon as possible.
It is best to simply rinse the car body as a habit after the rain stops. Because rain contains acidic components, if it remains for too long, it will corrode the car paint. Therefore, after rainy days, simply wash the roof, hood, body and other parts of the car with tap water. After all, every time a vehicle wades into water, it is a potential source of harm to the vehicle.
Generally speaking, except for professional off-road vehicles, the water-wading capabilities of family cars are relatively limited. Therefore, when facing water-wading roads, you should try to avoid it if you can. If it is really unavoidable, you should do it. Remember these tips from car buyers. Finally, I hope that all cyclists will be civilized and well-educated, and not drive too fast on rainy days to avoid splashing water on pedestrians.
