Why does the interior light of the G-Class not turn off after locking the car?
3 Answers
The reasons why the interior light of the G-Class does not turn off after locking the car are as follows: Headlight delay function is activated: The headlight delay function means that after turning off the engine, the system keeps the headlights on for an additional minute to provide external lighting for the owner after exiting the vehicle. This delay function serves as illumination. Short circuit in the wiring: If the interior light remains on continuously, it could also be due to wiring issues. It is advisable to visit a repair shop or an authorized dealership for inspection and repair. Deactivating the delay function: The headlight delay function is particularly convenient in areas without streetlights. It is important to note that to use this function, the headlights must be in AUTO mode. If you wish to deactivate it, you can do so through the vehicle's onboard computer.
I've encountered the issue of interior lights not turning off after locking the car quite a few times. It's usually caused by doors not being closed tightly enough for the sensors to respond, or minor control module malfunctions. The door control switches located in the door frame corners are prone to failure due to dirt accumulation or aging - you'll need to check all doors including the trunk are fully closed. If lights remain on after proper closure, try shortening the light delay time in dashboard settings (e.g. reducing from 10 seconds to 5 seconds). Otherwise, it might be a stuck relay or issues caused by unstable/overcharged battery voltage. Address this promptly to avoid complete battery drainage overnight which could leave you stranded in the morning. While checking fuse boxes for blown fuses is an option, visiting an authorized repair shop for diagnostic scans is safer. Some vehicles have sensitive electrical systems where DIY repairs may cause errors - leaving it to technicians is more reliable. Developing good light-checking habits when parking can prevent most issues.
I used to make this mistake too when driving. After locking the car, the lights were still on and I thought the car was broken, only to find out that the rear door opened with just a light touch. If the door isn't closed properly, the sensor won't work and the lights stay on. First, make sure all doors, including the hood and trunk, are tightly closed and listen for the sound. Then try adjusting the car's settings, like shortening the lighting delay option in the menu. If that doesn't work, the switch might be broken or the wiring oxidized, causing poor contact. The battery can be drained, and if it's severely depleted, the car won't start, requiring a tow truck, which is a headache. It's recommended not to stubbornly try to fix it yourself unless you know how to safely use a multimeter to measure voltage. Get the door sensors and control box checked at a repair shop in time to avoid future troubles. Develop the good habit of checking the lights a couple of times after locking the car to save trouble and battery.
