Hello I will help you with your question,
This is the lamp mounted on the rear shelf and you don't have a spoiler?
If so press on the leading edge of the lens at the shelf to release the lock under the shelf. While pushing lift the lens cover off the shelf and you will have access to the bulb
Let me know if you have the spoiler and if you have further questions
Let me post a diagram for you
Combine both procedures to release the hooks from under the package tray to lift the lamp cover
Let me know if this works for you
