Welcome to the GLA forum. IIRC, Collision Prevention System Assist Plus is part of the Distronic system. However, if I'm not mistaken there is still a standard collision prevention system operating, which is what might be confusing. Guessing the Plus system doesn't activate because you have don't have Distronic.
MB seems to do that with other things. For example, my early 2016 production model (September 2015) has the menu options and jacks to activate Apple CarPlay and Android Auto, yet the wiring and connectivity for it wasn't available until production after 1 December 2015 as a special order option.
Recommend you verify with a MB service facility to be sure. Otherwise, there's probably an issue that needs attention. Please let us know what you learn.
