LaTeX.org

I solved it.

I had to change the default names of Babel package, in this case, the brazilian captions:

\addto\captionsbrazil{
\renewcommand{\chapterautorefname}{Seção}
\renewcommand{\sectionautorefname}{Seção}
\renewcommand{\subsectionautorefname}{Seção}
}

So, the Chapter, Section and ...

I want do redefine Section and Subsection in autoref names the same way
do with Chapter names.

How i do that?
