Airbags also have a "preservation period"

In fact, some things used inside the car have a "preservation period".For exampleairbag. Theoretically, the design life of the airbag is the same as the life of the vehicle, but the actual life is not that long. Even if the airbag does not detonate after 8 to 10 years of use, the quality is difficult to guarantee. After every 10,000 to 20,000 kilometers, you should go to the 4S shop to check the airbag and its accessories. Things like airbags that can save lives in a crisis, don't let them become a decoration.

The wiring length of the car is up to 1kilometer!

What annoys the repairman most is the wiring problem. Because the wiring length inside the car is really long! The internal wiring of a car is as complicated as the structure of the human body.

So the biggest headache for repairmen is the wiring problem.

Although the safety measures at gas stations are now in place, smoking is not allowed, and there are static elimination devices when self-service refueling. But having defensive protection measures does not mean that it must be very safe when refueling.In fact, the fuel gun is very easy to introduce stray current into the cartank, Which may increase the molecular motion of unstable gasoline, which may cause safety hazards such as fires and explosions.

Jump off the car in an emergency, never jump forward

In an emergency, if you jump out in the direction of the car, you are dead! When the car jumped, due to the law of inertia, it accelerated forward with the speed of the car, and then fell to the ground severely. Therefore, if you jump forward, your body will lean back when you hit the ground, the risk of hitting the back of the head is greater, and the death rate is very high. No one wants to have an accident while riding a car, but if you have to, you must remember this when you have to jump off the car.
