Hi Stasey - congratulations on your new Pilot purchase and welcome to the forum!
If you are enquiring how to access the under-floor storage area in the rear cargo area, move any floor mats that may be present to expose the cargo lid. Then pull the handle to open the cargo floor lid.

 

Youtube has some video demonstrations on how the cargo lid works.
Search for "Honda Pilot 2016 cargo"

*It tells me I can't post links.*

Hope that helps.

Here are a few videos. I don't know whose voice sounds mildly creepier, the second one or the third.
