When resting inside a vehicle, it is important to be mindful of the following points:
1：Ensuring sufficient ventilation is crucial. Avoid keeping the car completely sealed; allowing air to circulate is vital.
2：Carefully choose a parking spot. Avoid parking in cramped or poorly ventilated areas and try to park in locations where oxygen supply is adequate.
3：Use the air conditioning wisely. For short naps, you can turn on the air conditioner and use the internal circulation mode to ensure basic ventilation; however, be cautious when sleeping for long periods to prevent carbon monoxide poisoning.
4：Before sleeping, slightly open the windows to allow air exchange between the inside and outside of the vehicle. This step is very important for maintaining air quality.
5：For safety reasons, be mindful when selecting a parking spot. Avoid parking in unsafe areas, especially in poorly ventilated places like underground garages, and protect personal valuables.
