What does it mean when a person is holding a ball on the car?

[LaLillian]

A person holding a ball indicates a fault in the safety system. The car's safety system is mainly divided into two aspects: active safety systems and passive safety systems. The airbag is a passive protection device in the vehicle. In the event of a collision, it prevents the occupants from colliding with the vehicle's internal components, thereby avoiding serious injuries. The airbag works in conjunction with the seatbelt to provide more effective anti-collision protection for the occupants. Solution for the airbag warning light: If you want the airbag light to turn off, simply rotate the car key to the 'on' position. If the airbag warning light flashes for 5 seconds and then stays on while the vehicle is running, it indicates a fault in the airbag system. The owner should promptly take the vehicle to a 4S shop for inspection and repair. Airbag precautions: Use with seatbelts: From a design perspective, seatbelts not only provide protection but also control the speed of the occupant's body during the early stages of a collision, ensuring that the occupant contacts the airbag at the right moment and position to minimize the impact force generated by the airbag. Avoid placing items near the airbag: The airbag deploys with tremendous force, reaching an instantaneous speed of 250 km/h to 350 km/h and an impact force of 150-200 kg. Placing items near it can cause secondary injuries when the airbag deploys. Avoid accidental impacts and modifications: On one hand, avoid strong impacts or vibrations that could trigger the airbag sensor abnormally. On the other hand, be cautious during modifications. Accidentally altering the airbag system wiring may render the airbag ineffective. Another consideration is the installation of seat covers, which can affect the deployment of side airbags. Seat and posture adjustment: The danger zone for the driver's airbag is within 5 to 8 cm in front of the inflation system. Therefore, maintaining a distance of 25 cm from the driver's airbag ensures safety. This distance should be measured from the center of the steering wheel to the sternum. Additionally, since the airbag inflates at speeds up to 320 km/h, incorrect seating posture during a collision can cause severe injuries. Do not let children sit in the front passenger seat: While airbags and three-point seatbelts provide optimal protection for adults, they can be disastrous for children. During a collision, the seatbelt's pull may cause chest fractures in children, and the deploying airbag could lead to suffocation, which can be fatal. Therefore, it is safer to place children in a rear-facing child safety seat. Airbags have an expiration date: Due to manufacturers' secrecy regarding airbag technology and the lack of related standards, many believe that the lifespan of a car aligns with the design life of its airbags. However, this is not the case. Airbags may not be reliable after 8-10 years of use, so it is recommended to perform maintenance every 10,000 to 20,000 km. If the airbag warning light continues to flash or stays on for 6-8 seconds after starting the vehicle, it should be inspected at a 4S shop as soon as possible.
