Let's take a look at some interesting and practical car knowledge.
1. The airbag in a car has a life span of 10 years at most, no matter it is used or used, and it must be replaced when it expires, otherwise it will fail!
2. During thunderstorms, gas stations generally will not refuel the drivers, because the air will contain electric particles, which can easily cause fires and explosions!
3. The brakes in the car are designed to be higher than the throttle, in order to avoid allowing the driver's friends to confuse the brake and the throttle when driving, causing a major traffic accident!
4. When the car needs to jump to escape during an emergency during driving, jumping backward can offset a certain speed, and the impact force will be less when it hits the ground!
5. In summer, you should always disinfect the compartment, because sneezing in the compartment or touching the seat, armrests, etc. will leave a lot of bacteria. If the air is not circulating, it will become a breeding ground for bacteria!
6. The glass water used for car cleaning windshield is blue. At this time, because the manufacturer wants to remind the car owner that this is a toxic liquid, pay attention to safety when using it!
7. Some cars are also equipped with a switch in the trunk. This is for people in the car to put down the rear seats and escape from the trunk in the event of a traffic accident!
8. The seat belt in the car can actually be adjusted up and down. Some friends always feel uncomfortable wearing the seat belt when riding in the car. It is caused by the height position not being adjusted properly!

How long will the new car be maintained and the precautions for the running-in period
How long does it take to maintain a new car? This problem is very simple. New cars are usually maintained within 3 months or 5,000 kilometers. The specific time varies slightly between different brands and models. It is recommended that car owners can also consult with 4S points to confirm. The following will introduce the "car running-in precautions" for netizens. .

　　 1. Avoid overloading

　　 The load of the car during the running-in period cannot exceed 75% of the rated load. The new car should be less than the specified load and number of people when it is loaded, and it should not be overloaded. Overloading will increase the burden on the engine, transmission, transmission system, suspension system and other components and accelerate wear. Generally speaking, domestic cars cannot exceed 75% of the rated load, and imported cars cannot exceed 90% of the rated load. In addition, in order to reduce the load on the body and power system, a relatively flat road surface should be selected to avoid vibration, collision or emergency braking.
2. Do not drive at high speed

　　 There is a speed limit during the running-in period of the new car. Generally speaking, domestic cars are within 40~70 km/h, and imported cars are generally within 100 km/h. Ensure that the engine speed and vehicle speed work at a medium speed. Under normal circumstances, the engine speed should be 2000~4000 rpm during the running-in period; avoid running long distances. If the car runs long distances during the running-in period, the continuous working time of the engine will increase, which is easy to cause The parts are worn out. In addition, you should shift gears in time when driving to avoid driving at high gears and low speeds and low gears at high speeds. Generally speaking, the speed of each gear is controlled within 3/4 of the top speed; during the running-in period, the car should also pay attention not to make emergency braking as much as possible, and strive to achieve slow start and slow stop.
3. Use high-quality gasoline

　　The gasoline used in the new car during the running-in period should not be lower than the label specified by the manufacturer. Do not add anti-wear oil to avoid insufficient running-in when the mileage is enough. In addition, the correct adjustment of the ignition system and the fuel supply system can solve the changes in the vacuum fuel economizer caused by the installation of the speed limiter, and improve the economy of the running-in period. In addition, correct and reasonable driving also includes lightly depressing the clutch and accelerator pedal when starting. After starting, it should run at low speed, warm up to 50℃~60℃ and so on.
