How to open car windows without starting the engine?

[OQuinn]

To open car windows without starting the engine, you can simply turn the key to the ON position. At this time, the car is only powered on but not ignited. Some car models allow window operation using the remote key. When the vehicle is not started, press and hold the unlock button on the car key for 2 to 3 seconds, and the windows will automatically roll down (including the sunroof). Similarly, pressing and holding the lock button will make the windows roll up automatically. Opening a single side window while driving can provide ventilation, especially when smoking inside the car - opening one window allows smoke to dissipate quickly. However, it's recommended not to smoke while driving as it may interfere with normal driving operations. If there are odors inside the car, opening three windows simultaneously can help eliminate them quickly because this method creates abnormal air circulation with clear directional movement. Opening windows diagonally opposite each other while driving can reduce interior noise while maintaining good ventilation without affecting normal driving.
