2017 freightliner cascadia what are these buttons for (picture)

Have u tried pressing them to see what happens.

 

Those aren't standard buttons from Freightliner. Unless someone here just happens to recognize them, your carrier would probably have the best answer.

 

Maybe they added a axle lock since it’s only a 2 way from factory red button lights up light below it??

 

Red button is, was for Military loads, ammo, DoD loads.
Panic button, as some loads have an unmarked government vehicle close.
It’s gets attention.
Sometimes they disconnect them if sold.

You’ll have to pull dash and unhook it.

 

Dude just push them and see what happens
