The service life of airbags is generally about 10 years. Usually I don't know much about the use and maintenance of airbags. I'm afraid in case of an accident, it can't play the role of safety protection.
Airbags need regular maintenance
It is understood that at present, the maintenance of airbags requires computer testing when driving about 30000 km, which is often referred to as "major maintenance" by 4S stores.
Li manager, an expert in chain maintenance of Huasheng Benz, BMW and Audi, said that when driving normally, the driver should pay attention to the airbag warning light on the dashboard. Under normal circumstances, when the ignition switch is turned to "ACC" or "on" position, the warning light will be on for a few seconds, and it will go out after self inspection. If the warning lamp is on for a long time, it indicates that there is a fault in the air bag system, which should be repaired. Otherwise, the airbag may not work or eject by mistake.
The maintenance of the air bag system is different from other systems of the vehicle. If the operation is wrong, the air bag may detonate accidentally, causing casualties. Different manufacturers use different sensors, inflator types and stages, detonating circuit layout, propellant and so on. Therefore, the maintenance personnel shall be equipped for the maintenance of the air bag system, and the maintenance shall be carried out in strict accordance with the provisions of the maintenance manual for each vehicle type.
Do not hang accessories on the rearview mirror
The first thing to remind you is that drivers and passengers must fasten their seatbelts. Without safety belt, air bag can not only protect passengers, but also hurt drivers and passengers.
Mercedes Benz repair expert master Luo said, do not knock or hit the airbag position. Moreover, because the damped airbags cannot protect the life safety of the driver and passengers at the critical moment, it is not necessary to wash the position of the airbags directly with water. When the car is equipped with front double airbags, do not let children sit in the front row or put the child seat in this position. As the impact force of air bag cannot be borne by children, it will cause harm to children.
Manager Li stressed that no ornaments should be hung on the front windshield and inside rearview mirror. When the airbag is ejected, the suspended accessories will crash and fly to the driver and passengers, causing unnecessary injury.
Do not place hard or sharp objects between the airbag and the driver or at the marked parts outside the airbag, otherwise, the strong impact force when opening the airbag will press it against the driver's body and cause serious injury.
