Here are the specific methods to set the interior light to turn on when the door opens: 1. Light assembly button: There is a light assembly button near the door that controls all interior lights. Press the interior light button to turn it on. 2. Function button: Next to the light assembly button, there is a function button. When it is off, it shows a yellow light, and the interior light will not turn on when the door opens. When it is on, it shows a blue light, and the interior light will turn on when the door opens. Below is extended information on the classification of car lights: 1. Headlights: Combined headlights are located at the front of the car, primarily serving the purpose of illumination and signaling. The light emitted by the headlights illuminates the road ahead, allowing the driver to drive safely at night. 2. Combined taillights: Combined taillights are located at the rear of the car, mainly serving the purpose of illumination and signaling. 3. Turn signals: Used to indicate to other road users that the car is turning left or right. Regulations require them to be amber in color. 4. License plate light: The license plate light mainly illuminates the license plate, making it identifiable at night.

I often share these kinds of tips in car enthusiast groups because helping others solve car-related problems gives me a sense of achievement. The feature where the light turns on when the door opens can usually be adjusted in most car models. The common method is to find the switch on the overhead control panel, which typically has three positions labeled: door-controlled, always on, and off. Try turning it to the door-controlled position. Some newer cars allow you to adjust this through the dashboard settings menu under the lighting options—select the door-triggered mode. Older cars might require checking if the relay is properly connected or installing an adapter. The battery condition can also affect this function, so ensure the system has stable power. Bulb lifespan and switch aging are common issues, so regular cleaning and rust prevention are advised. If the light doesn’t turn on after adjusting, it might be due to a blown fuse or wiring fault, requiring simple troubleshooting. Before attempting any fixes, refer to the owner’s manual or look up a guide for your specific car model online to save time and effort.
