I only see one thread on removing a wheel cover in Gen III section, so here it goes... I removed a plastic wheel cover for practice and easier access to check wheel nuts at 76 ftlb (listed as something to check in owner's manual). Also plan on keeping wheel covers at home before it goes in for tire rotation maintenance. Do as manual says - use the wheel nut wrench with the pry tool, use a rag to protect wheel. You will need pull the cover nearby with other hand as you pry and it will pop off. Before I thought it was ok to remove without the pry tool, just yank, but don't try that. I think it will result in breaking a wheel cover. It's possible to get the 21mm socket through the cover holes, but it's a real tight fit. Little grease will help.
