DEF GETTING LOW WARNING

[skw774]

I have run mine until no little green bars show, never got any kind of warning on the DIC. So i asked the lack of knowledge service advisor and he said that was correct I am to monitor the little green bars and add accordingly. My 2014 before some things fell off would lose it's mind if it got low. Am i missing something or all of these L5P trucks like this ?
