To turn off the constantly lit SOS light in a car, simply press the corresponding light button back to its original position, or press the hang-up button on the steering wheel. The SOS system in a car is an onboard self-rescue system designed to quickly seek emergency assistance when the vehicle experiences a malfunction, is involved in an accident, or encounters dangerous and sudden situations. The structure of the onboard self-rescue system includes a winch drum connected to a fixed worm gear reducer, with a 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 U-shaped bracket has a fixed hook installed on its back, and a steel cable is wound around the winch drum, with one end of the cable tied to an anchor hook.

I've encountered a similar issue before. The SOS light in my car stayed on inexplicably, and I later found out it could be due to a software bug in the vehicle's system or unstable battery voltage triggering protection. The first step is to find a safe place to park, turn off the engine, and wait a few minutes before restarting. Sometimes this can resolve temporary software glitches. The manual shows the location of the reset button—try that. If the light remains on, you might need to check via the mobile app or the car's screen to see if the emergency service subscription has expired, as many modern cars rely on subscriptions for SOS functionality. If the problem persists, it's essential to visit a 4S shop or a professional repair station to diagnose the error codes with specialized equipment. Avoid forcibly turning it off to prevent false alarms, which could waste resources and disrupt normal use. Regularly updating the system version can help prevent such issues.

I've been driving for over a decade. If the SOS light stays on continuously, you need to be cautious - it could be a system misjudging an emergency or hardware issues like a short circuit. My advice is to immediately pull over, turn off the engine, and check the user manual for reset procedures. If that doesn't help, contact your dealer right away - don't delay too long to avoid battery drain or accidental emergency calls. From personal experience, common causes include dusty sensors or maintenance oversights. I recommend cleaning the roof antenna area during every car wash and checking in-vehicle network stability during seasonal changes to prevent minor issues from becoming major repairs that compromise driving safety.

As an ordinary car owner encountering a constantly lit SOS light, here's a straightforward solution: After parking and turning off the engine, wait for ten minutes before restarting the car. Most systems will perform a self-check and reset, turning off the light. If that doesn't work, try using the control buttons on the steering wheel to force it off or refer to the manual to locate and reseat the fuse. If the issue persists, simply drive to a nearby repair shop where they can fix it in minutes at a minimal cost—far better than attempting disassembly. To prevent false triggers, remember not to place items that might press the SOS button. Prioritize convenience, simplicity, and safety above all.
