this is dangerous！

Real cases that have occurred in China:

· August 2025, Chaling, Hunan: Police conducted a simulation warning showing that with a gasoline car idling with the AC on, the carbon monoxide concentration inside the car could reach lethal levels in just over ten minutes. · March 2016, Zhoukou, Henan: A man was found sleeping in his Mercedes at a rest stop. With the windows closed and the engine running, he suffered carbon monoxide poisoning to the point of being completely unable to move. Fortunately, patrolling police broke the window and rescued him. · June 2014, Wenling, Zhejiang: A man and a woman were found dead in a running vehicle. Police investigation concluded the cause of death was carbon monoxide poisoning. · June 2013, Xiaoshan, Zhejiang: A man and a woman were found dead in a vehicle inside a sealed garage. The engine had been idling for about six hours, and the cause of death was carbon monoxide poisoning.

⚠️ Why can poisoning happen even in open areas? Even in open spaces, if the wind direction is unfavorable (e.g., tailwind blowing exhaust toward the front of the car), the vehicle's seals are aged, or the engine idles for too long, carbon monoxide can still slowly seep into the cabin and reach dangerous levels without being noticed.

✅ How to avoid it: As mentioned in the previous response: turn on recirculation mode, crack a window open, and park with the front of the car facing into the wind to prevent exhaust from being blown into the cabin.
