Gather necessary tools and ensure the vehicle is parked safely.
Disconnect the 12V battery for safety before working on electrical components.

Locate the door sensors on each door.
Check for any debris or damage that could prevent the sensors from detecting when the door is closed.
Clean or realign sensors as necessary.

Navigate to the "Controls" menu and select "Lights."
Verify that the "Interior Lights" setting is configured to turn off when the doors are closed.

4. Test Interior Light Switch

Locate the interior light switch, usually found on the overhead console.
Ensure the switch is not in the "On" position; if it is, switch it to "Auto" or "Off."
If the switch is malfunctioning, consider replacing it.

Press and hold both scroll wheels on the steering wheel until the touchscreen resets.
Wait for the system to reboot and check if the interior lights turn off as expected.
