What is the reason for reminding "Please check the airbag" when Chuanqi gs4 is driving?

Poor contact of harness or collision sensor.

Airbags are installed at the front (front row and co-pilot position), side (front row and rear row) and roof of the car. The auxiliary inflatable restraint system (SRS) is printed on the outside of the container with airbag system, which literally translates as "SRS" in Chinese.

The airbag consists of three parts; The first is the airbag itself, which is made of fine nylon fiber and folded in the steering wheel or dashboard; Then there is the sensor that tells the airbag to inflate, and the sensor can detect the impact force equivalent to 16-24 km/h; Finally, the inflation system, the airbag is actually inflated by a system similar to the solid rocket booster. Sodium azide (NaN3) and potassium nitrate (KNO3) react rapidly to generate a large amount of hot nitrogen, which inflates the airbag and rushes out of the steering wheel or dashboard when the airbag inflates.

Airbag is the auxiliary protective equipment of airbag system, which is made of special fabric nylon, lined with rubber and filled with harmless nitrogen when working. In the event of a collision, it takes about 0.03 seconds for the airbag to inflate. The very fast inflation speed ensures that the airbag can be in place in time when the passenger's body is bound by the seat belt and his head is still moving forward. When the head touches the airbag, the airbag begins to exhaust through the pores on the surface of the airbag. The gas is discharged at a certain speed, which ensures that all parts of the human body slow down. Because the speed of airbag inflation can be as high as 320 km/h, if people sit incorrectly during collision, it will bring serious harm to people.
