The reasons why it is bad to sleep in a parked car with the air conditioning on are: 1. It increases the production and retention of engine carbon deposits; 2. It is not conducive to effective heat dissipation, leading to high engine water temperature; 3. It places a greater load on the engine cooling system; 4. It reduces the service life of the engine; 5. It may cause carbon monoxide poisoning for the occupants. The method to turn on the air conditioning is: 1. Turn the knob in the air conditioning control area to cool or heat; 2. Press the AC button when cooling. The functions of the car air conditioning are: 1. To provide a comfortable environment for passengers and reduce travel fatigue; 2. To create good working conditions for the driver.
Once, I parked by the roadside and slept with the air conditioning on, which almost led to a disaster. The engine kept running, and the toxic carbon monoxide it emitted gradually accumulated in the enclosed cabin. When I woke up, I felt dizzy and nauseous, and after checking, I realized these were signs of poisoning—it was terrifying. In dangerous situations, it could be fatal, especially in poorly ventilated areas like parking lots or garages. So now I’ve developed a habit: no matter how tired I am, I turn off the engine before taking a nap. Safety first—don’t risk big losses for small gains. Health is more important than anything. Nowadays, I make sure to stop at rest areas or park near open windows for ventilation to protect myself. After all, being cautious about such things in life can save your life.
