What does it mean when the vehicle's SOS light is on?

When the vehicle's SOS light is on, it refers to the onboard self-rescue system, which is an emergency system designed to quickly seek rescue assistance in the event of an accident. The onboard self-rescue system consists of a DC motor, a worm gear reducer, a U-shaped bracket, a winch drum, a hook, a steel cable, a cigarette lighter plug, a switch, and an anchor hook. The structure of the onboard self-rescue system involves connecting the winch drum to a fixed worm gear reducer, with the DC motor mounted on the reducer's housing. The current input of the DC motor is connected to the cigarette lighter via a wire switch, a fixed hook is installed on the back of the U-shaped bracket, and the steel cable is wound around the winch drum with one end attached to the anchor hook.

Recently, the SOS light in my car suddenly turned on, which made me quite nervous. This light usually indicates an issue with the vehicle's emergency assistance system, possibly a malfunction in the eCall service or a failure in the safety module. Common causes include a weak battery, loose antenna connection, or a faulty sensor. The exact cause needs to be checked against the vehicle's manual. If this happens while driving, I recommend staying calm, pulling over safely, and trying to restart the car by turning off the power to see if the issue resolves. If not, it's best to visit a 4S shop or consult a professional mechanic for diagnosis, as the system involves communication functions. In case of a real emergency, failure to call for help could be a serious problem. Regular vehicle maintenance is crucial—check the battery and wiring periodically, avoid water ingress during rainy days to prevent short circuits, and always prioritize preventive measures over post-incident panic. Safe driving should always come first.

When the SOS light in the vehicle comes on, it generally indicates a malfunction in the built-in emergency alarm system. Possible causes include unstable battery voltage, broken antenna wiring, or a faulty control module. From a repair perspective, first open the hood to check if any fuses are blown, then use a multimeter to test the circuit continuity. If you're not confident in your DIY skills, it's best not to delay and take the car directly to a workshop for inspection to prevent minor issues from escalating into major safety hazards. As a side note, most new cars now come with such smart systems. In daily use, avoid sudden acceleration or long-distance rough driving, which can damage fragile components. Learning some basic maintenance skills can save a lot of hassle. From my years of driving experience, addressing these issues promptly ensures both safety and cost savings.

Never ignore the SOS light as it directly indicates a failure in the vehicle's emergency call function. This means pressing the button may not send a distress signal during accidents or emergencies. Common root causes include poor SIM card slot contact or insufficient power supply. It's advised to pull over immediately, check the user manual for error codes, and seek professional repair if unresolved. Don't dismiss it as a minor issue – it's a matter of life safety. All drivers should regularly test the system to ensure proper functionality.
