What does it mean when the preventive safety system stops working?

Preventive safety system stop working means that the vehicle's airbags, active head restraints and pre-tensioned seat belts will all stop functioning. Below is relevant information about the preventive safety system: 1. Function: During emergency braking, the enhanced brake assist system quickly calculates the required braking force for the current situation. During emergency avoidance maneuvers, the electronic stability program rapidly stabilizes the vehicle to reduce the risk of skidding. 2. Definition: When encountering dangerous situations such as severe oversteer, understeer, sudden steering movements, panic braking or emergency braking, this system can take preemptive measures including automatically closing the sunroof and side windows, tightening seat belts and adjusting power seats to a more appropriate position.
Seeing the warning message 'Preventive Safety System Inoperative' pop up on the dashboard means that the vehicle's active protection functions, such as collision warning or automatic braking systems, have stopped working. This usually occurs when sensors are obscured by dust or mud, due to electrical circuit malfunctions, or software bugs. With years of driving experience, I know this issue should never be taken lightly—these systems are designed to prevent emergencies, and if they fail, they won’t alert or intervene in dangerous situations, significantly increasing safety risks. Common causes also include loose wiring from rough roads or unstable battery voltage. It's recommended to visit a professional repair shop immediately for diagnosis—they can use computer diagnostics to identify the root cause, and in most cases, cleaning the sensors or updating the software will resolve the issue. Regularly paying attention to cleaning the radar areas during car washes can help prevent such problems in the first place.
The preventive safety system malfunctioning really gave me a scare, as it means the vehicle loses those accident-preventing capabilities, like when the car ahead suddenly brakes at high speed—no warning could spell big trouble. The issue might stem from rainwater seeping into the sensors or aging electronic control units. Ignoring the warning would drastically increase accident risks during night driving or in harsh weather—the system meant to save lives now does nothing. My approach is to immediately pull over and check if the dashboard shows a red warning light. If cleaning it myself doesn’t help, I’ll contact the 4S shop for repairs. Safety first—don’t risk big to save small. Regularly monitoring your car’s condition is always wise.
