Should You Leave a Small Gap in the Car Window When Parking for a Long Time?
2 Answers
It is generally not recommended to leave a gap in the car window when parking for a long time, as it may attract thieves and lead to the theft of items inside the vehicle. Here are some reasons why people might consider leaving a small gap in the window: 1. Lowering the interior temperature: Studies show that leaving the window slightly open can reduce the interior temperature by 20-30 degrees Celsius compared to a completely sealed car when parked under the sun. 2. Reducing interior odors: Many cars have strong interior odors, especially when exposed to sunlight. Leather and other interior materials can release harmful gases, including formaldehyde and benzene, under high temperatures. If the windows are completely closed, entering the car may expose you to these odors immediately. However, leaving a small gap in the window allows air circulation, which can help alleviate this issue.
When I park for over a week, I sometimes leave a small window gap for ventilation to prevent odors and moisture buildup inside the car. But this depends on the situation: it’s acceptable in secure neighborhoods or garages, though too large a gap may attract dust or animals. The key is controlling the size—about half a centimeter is enough. Never do this during rain or snow, as water seepage could corrode electronics or soak the carpets. Additionally, high interior temperatures accelerate plastic aging, and a small gap helps dissipate heat. If security is a concern, I recommend using window rain guards or activated charcoal packs inside the car—they allow airflow without exposing the interior. Remember to check regularly and don’t overlook theft risks.
