Reviewing your album and noticed your remote for engine start is not the same as in the Accessories guide, see below Your Key And here is a pic of the Rear bumper applique
+1. I'm assuming it's a function of which model you are buying. The AC button is for the IV. FYI, I have no idea why they put that little sticker by the panic button, since you only use the lock button to start the car (2 quick presses, and then a 3rd press for 3 seconds). You press the unlock button to stop it. oh, and I've decided to live with the black bumper, but thanks for the pic anyway.
