What should you pay attention to when driving in a rainy day?

In recent days, heavy rainfall throughout the country has caused secondary disasters such as floods and floods. Severe urban floods have occurred in Wuhan, and floods around the city have affected both the vehicles and people. Especially in the rainy weather, there are many places to pay attention when the vehicle travels. The driver's friends will learn about some of the techniques and places that should be noticed during the rainy days to ensure the safety of the car.

First, rainy days driving considerations

According to the International Driving Safety Survey, traffic accidents in rainy days are about five times higher than usual. Drivers must be vigilant when driving in rainy weather.

1. If the wading depth exceeds the front bumper, caution should be exercised when driving. If it is found that the air filter is wet or influent during the inspection, it should be stopped and checked to avoid engine water.

2, if the wading depth exceeds the engine compartment cover, it is recommended not to drive, immediately stop and stop. Otherwise it is easy to have a "valve top". If you turn off the fire when you pass water, do not try to start the fire again.

3, do not go through the ditch and puddle at high speed. This will cause splashes, which will increase the depth of actual wading, and will easily lead to engine flooding.

4, do not see left water to avoid the right side of the water. It is a common problem for the average person to see the water flash, or to put on the brakes to slow down. In fact both methods are very dangerous. Left-right and left-right avoiding the driver can easily misunderstand and cause accidents.

5, to maintain a sufficient safety distance. Since the braking distance of a car will increase due to rain, a certain safety distance should be maintained when driving.

6, wiper is best changed every year. If the wiper's ability to sweep water drops, it will be difficult to observe the road conditions during rainy days. Especially when driving at high speeds, the wiper blade floats upward and the ability to sweep water is even worse. In addition, the rain in the rain, no scraping rain will produce a variety of reflected light in the light, so that the front of the vision is extremely vague and easy to cause accidents.

7, to the car glass wax. If the glass cleaner contains some wax, it can form a wax film on the glass surface after use, the wiper will sweep the water thoroughly, and it can also protect the glass.

8. Regularly check whether the waterproof tank drainage at the front windshield is smooth. Avoid water in the engine caused by water in rainy days and prevent short circuit in the onboard computer. FAW series models of computers in the water tank.

9, regular inspection of tire wear and timely replacement. Excessive wear of the tires makes it easier to form a film of water between the tread and the surface of the water, causing car deviation, tail flicking, and extended braking distances.

10, see more and watch more. Many car mirrors do not have automatic heating function. The raindrops that accumulate on the exterior mirrors during rainy days are likely to cause blind spots on the driver's line of sight. In addition to promptly cleaning the exterior mirrors, drivers must pay more attention when they are in line.

11, night rain, cloudy driving, timely opening night driving lights. Traffic visibility at night is poor. In order to prevent rear-end rear-end collisions, nighttime driving lights should be turned on. In addition, on cloudy days, heavy rain and fog, and poor visibility, rain lights should also be turned on at night.

12. Pay attention to the drainage system when installing the sunroof. Skylight leakage is a very annoying thing, but the sunroof drainage system is sealed on the roof, so it is not easy to check. Generally the skylight's drainage pipe will be thrown to the C- pillar position, and sometimes it will be placed on the B- pillar position. When installing the sunroof, we must pay attention to the regular and unobstructed drainage system installation, otherwise we can only enjoy the “rainy weather” time in rainy days.

13. Do not turn off the engine when parking in rainy weather. Although there is a hood to prevent rain, it is inevitable that there will be gaps and splashes of water splashing on the ground, causing the engine to fail to start after rain.

14. Do not reduce tire pressure by driving on rainy days. According to some experience, some air in the tires is let off before driving in rainy weather to flatten the tires to increase the contact surface, increase friction and prevent slicks. However, this approach is not desirable. The method of reducing the gas in the tire to increase the coefficient of friction is very limited. When a car brakes in the rain, the most important thing is to have enough pressure to drain the rain between the tire and the road, so as to stop the car. The tire contact area becomes larger, the pressure per unit area on the ground decreases, and the braking force decreases, and the rainwater between the tire and the ground cannot be quickly discharged, resulting in a longer gliding distance.

15, road sand more easily slippery. At the beginning of the rain, especially after drizzling, road dust and sand have not yet been completely washed. Sand that has absorbed moisture becomes clay, and it is very easy to slide the tire. After a while under the rain, the sand is completely washed away and the road conditions will be better.

16, for the unknown depth of the road, get off or wait. The depth of water exceeds the exhaust pipe, and it is easy to cause a car to be extinguished. The water depth exceeds the bumper, and it is easy to infiltrate from the air filter and the air inlet. For roads with unknown depths, it is best to get off the car or wait, so as not to cause the engine to enter the water and extinguish the flames.

17, for the window fog can open the cold wind choose to blow the glass stalls, open the outer loop for the filter will cause moisture absorption, resulting in air conditioning odor.

18, the market sells 'rain enemy' and other products can play against the outside of the glass to prevent fogging effect, but I test 'cleaning spirit' have a better effect, even before the rain with a paper towel stained washing spirit evenly applied mirror , triangular window, you can not worry about fogging. This method is a one-time, after the rain should continue to smear, it is best to find a container to drink a little in the car back.

19, even after the wading drive should be stepped on the brakes, so that the draught in the draught tray to dry out, or the disk body rust or because of water to reduce braking capacity.

Second, rainy days misunderstanding

1, the cart is not easily flooded

This is a misunderstanding. Just last week, a Q7 was flooded after the owner sent nine friends. Zhang Ye reminded his friends that the car's displacement was large and the water intake was large. It was not that the car wouldn't be flooded. It was a good idea to drive in a rainy day.

2, bought wading insurance is not afraid of being flooded

The wading insurance is not what you imagine. The major insurance company’s wading insurance clearly stipulates that if the engine is turned off after the flame is turned off, the engine water is no longer covered by the insurance coverage. Generally, it also costs a few hundred dollars. Cleaning fee. So, if into the water, never stop ignition, because the engine is the heart of the vehicle, repair or replace costly, generally it takes 4 to replace, more than 50,000 yuan.

3, increase the rapid passage of throttle

Many people think that driving too low a part of the road, the most fearful is the exhaust pipe into the water, so we must increase the speed of the throttle. "In fact, this view is a serious misunderstanding." Experts said that in general, the exhaust pipe will not enter the water, a video on the Internet shows that even if the water overflows the exhaust pipe, it will not affect the car. Start and drive.

The real cause of flameout is the intake of the engine air inlet. Generally speaking, the air inlet is in the front position and can be seen by opening the lid of the engine. According to different models, the location of the air intake is also different, the general air intake of German cars is located above the bumper, and many Japanese car air intakes are level with the bumper, if the throttle is quickly adopted in the wrong way, The resulting wave pushes back and it is very likely that the air inlet located at the front of the vehicle will be “drowning”, causing the engine to stall. The correct way to start is to pass slowly as low as possible, which is what people usually call "swift walking."

Third, the rain seven tips

1 , check the wiper, tire wear before going out.

2. Use brakes with caution on rainy days, especially when going downhill.

3 , rain and fog, open the front and rear fog lights in time.

4 , control the speed, do not make a sharp turn.

5 , driving in the rain, should always pay attention to the speed and direction of the car ahead, keep the safety car distance.

6 , vehicle wading must first explore the actual situation.

7 , slow down, pay attention to avoid pedestrians.
