Gently pull out on the rear edge of the wheel arch protector (A) to release the hooks (B).
Start the bottom to the middle of the wheel arch, pry the clip portions of the wheel arch protector up with a trim tool to detach the clips (C, D).
NOTE: Take care not to damage paint around a clip hole in the rear outside panel during clip removal. If paint is damaged, repair it with touch-up paint to ensure corrosion protection.
