It's not the procedure I personally used as my cover was already becoming detached as well as one of the retaining pins on the windshield not being fully engaged with the frame. It should however give you a direction to start.
Those instructions are for the non-camera mirror cover. You have to remove the small cover at the base of the mirror first, then you can remove the bigger cover. Be prepared that the small cover retainers may break and that you'll have to buy a new one to snap back it.
I suspected that may have been the case, though the picture looks much like mine with the camera in place. However, I should have remembered that this is the book for the '12, which doesn't include the FCA camera that was introduced in the '13s (which I have). At some point my smaller cover was removed and broken. I suspect by the dealership when the PO had it in for "front camera service required". Unfortunately it appears they used a couple spots of super glue to reattach it, which I had to pry off when I had to reattach the framework to the mounting pins on the windshield after I bought it.
Follow what El Dobro suggested regarding the small cover for the rear view mirror to start. He reminded me that the documentation I posted is for the '12, which didn't have the camera. I know when I've removed my piece on my '13, with camera, same as yours. I had to separate the cover from the frame that attaches the whole assembly to the windshield. There are several tension clips around the edge. As I recall, using both hands, with the thumbs centered on the center of the panel, I was able to pull the edges away from the frame while applying gentle pressure to the center of the panel. Basically spreading the sides away from the frame. Certainly not a lot of force was needed, but enough to bend the plastic slightly. I'm sure there is a more "official" removal procedure, but that worked for me as I had to reattach one of the retaining pin points that attach the frame to the windshield that apparently didn't get put back into place properly when the camera was last serviced.
I removed mine. I followed a photo tutorial from this forum, but I can't find it now to link you to it. I agree with the comments about removing the small section first. As I recall, it basically boiled down to pulling each part straight down with enough force for them to unsnap.
And I also agree about some potential breakage at the snap points. Mine all went back together securely despite some minor invisible damage. Worst case is you have to buy a new cover, so not the end of the world. If only the small section is a problem, you can leave it off and nobody will ever see it is missing.
