Well, I ask you to respect the order of the interventions such and which one I mention them, to avoid damaging some component or scratches the paint of the front fins.
1.- Disconnect the battery from the positive pole (optional)
2.- Open the motor capo
3.- Disassemble the screws that hold the bumper from the top.
4.- Disassemble the fenders
5.- At the bottom of the bumper are two tongues that hold it from the front, disassemble the screws (Torx Punta).
Finally you attach an image so that you have an idea of the place where the screws that hold it towards the fins go.
I hope my information helps you something.
