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.
When taking long trips with my kids, I often need to take a short nap in the car with the air conditioning on. My biggest concern is ventilation, so I leave a small gap in the window to allow fresh air in and prevent any risk of poisoning. The temperature should be set to a moderate level to ensure the kids don’t get too cold or overheat—around 24°C is usually comfortable. It’s also crucial to check that the doors are locked to avoid any unwanted disturbances while sleeping. I always make it a habit to check the position of the car’s exhaust pipe and park in open areas like roadside parking spots, away from dust and pollution sources. In terms of fuel consumption, idling for too long can be a burden, so I limit my naps to under half an hour to save on fuel and protect the engine. Additionally, using recirculation mode can save energy, but I avoid keeping it on for too long to prevent CO2 buildup. As a parent, safety always comes first—a short nap can help recharge, but I never overdo it.
As a young driver, when I occasionally feel tired, I just turn on the air conditioning in the car and take a short nap. The automatic air conditioning is very convenient—just press a button and set the temperature, and it automatically adjusts the airflow, saving the hassle of manual adjustments. Always leave the windows slightly open to ensure air circulation and prevent poisoning. Park in well-ventilated outdoor spots like parking lot corners, away from tall buildings that block airflow. Fuel consumption will increase, so I usually limit naps to 20 minutes and use the APP's timer function to shut it off, which is efficient and energy-saving. Set the temperature to a comfortable level around 20°C to avoid wasting fuel. Always lock the car to prevent theft. Additional reminder: don’t push it if the engine overheats. This method is practical during commutes, but don’t overuse it.
