Supplemental restraint systems (SRS), commonly known as airbags, along with seatbelts, are crucial safety features in BMW vehicles. A malfunction within this system can range from a faulty sensor preventing deployment in a collision to inadvertent deployment. Such issues can stem from various factors including damaged wiring, faulty control modules, or deployed crash sensors after a minor incident. For example, a malfunctioning seatbelt pretensioner might not properly restrain an occupant during a crash.
Proper function of these safety features is paramount for occupant protection in the event of an accident. These systems are designed to mitigate injuries by reducing the force of impact on vehicle occupants. Historically, automotive safety has evolved significantly, with restraint systems becoming increasingly sophisticated. These advancements have played a vital role in reducing traffic fatalities and serious injuries. Regular maintenance and prompt attention to any warning lights related to the SRS are essential for ensuring their effectiveness.
