Sleeping in a car with the air conditioning on can easily lead to carbon monoxide poisoning. Especially during hot summer weather, when the air conditioning is on and the car windows and doors are closed, the air inside the car cannot circulate. If carbon monoxide from the engine leaks into the car, it will gradually accumulate and increase in concentration, leading to poisoning. Precautions for sleeping in a car with the air conditioning on: 1. Pay attention to the surrounding environment: When sleeping in a car with the air conditioning on, it is advisable to be mindful of the surroundings. That is, when parking, you must carefully observe the environment. It is recommended not to park in dangerous places, such as areas prone to geological disasters, under large trees, or by the roadside, as these locations can easily trigger safety accidents, especially during extreme weather conditions, where secondary disasters may occur. 2. Remember to open the windows: When sleeping in a car with the air conditioning on, it is advisable to open the windows. Because the space inside the car is small, the concentration of carbon monoxide can become very high. If you sleep in the car with the air conditioning on without opening the windows for ventilation, the air inside the car will not circulate well, and the high concentration of carbon monoxide can easily lead to poisoning, causing severe and even irreversible consequences.

Finally, the warning light on the dashboard will turn off, indicating the tire pressure reset is complete. Tire pressure reset is an operation performed on the tire pressure monitoring system to reset it after resolving tire pressure faults. Abnormal tire pressure warning lights generally occur due to the following 3 reasons: Abnormal tire pressure: Typically, the system will alert when pressure is below 1.8bar or above 3.0bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure reset is not performed promptly, the tire pressure monitoring system will still record the original data, causing the tire pressure warning light to illuminate. Simply performing a tire pressure reset will resolve this. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is directly installed inside the tire and connected to the tire inflation valve. If the tire is impacted while driving, damaging the sensor, it can also trigger the tire pressure warning light. For sensor damage issues, the only solution is to replace it with a new component.
