Precautions for sleeping in a car with the air conditioning on include maintaining air circulation inside the car, turning on the external circulation mode, and regularly inspecting the exhaust pipe. Below are detailed explanations of these precautions: Maintain air circulation inside the car: If it's too hot and you need to turn on the air conditioning while sleeping in the car, it's important to regularly refresh the air inside. You can open several windows slightly, about two to three fingers' width, to ensure proper air circulation. Turn on the external circulation mode: Some drivers, due to the nature of their jobs, need to rest in their cars but may not always have a fixed location. Sometimes, they might even park in underground garages and rest inside the car. However, in confined spaces, carbon monoxide can easily accumulate. Therefore, when resting or sleeping in the car, always choose an open and spacious environment. Regularly inspect the exhaust pipe: Remember to check the exhaust pipe regularly. If carbon monoxide from the vehicle leaks into the car, it can easily lead to carbon monoxide poisoning. If the exhaust pipe is damaged, exhaust fumes are more likely to enter the car.
As a driver who has experienced several close calls, I always emphasize safety first when sleeping in the car with the AC on. Ventilation is crucial—never park in a garage or enclosed space, and always leave a window slightly open for airflow. Otherwise, carbon monoxide emissions from the engine can accumulate, leading to poisoning or even suffocation. I’ve personally witnessed a friend hospitalized due to this mistake. Additionally, it’s important to check the engine’s condition and ensure the exhaust pipe isn’t leaking. Prolonged idling also increases fuel consumption and wears out the car, so it’s best to set a timer or wake up every hour to adjust the temperature and avoid getting too cold. Keep the cabin temperature in a comfortable range—don’t set it too low to save battery. Finally, choose an open parking spot away from exhaust fumes and pedestrian areas, and lock the doors to minimize risks. While this method of resting is convenient, it carries significant dangers. I try to limit its use or opt for a safer place to nap. Nowadays, when camping, I bring a carbon monoxide detector for an extra layer of protection.
