Diff lock with MTS?

On page 307 of owner’s manual it says if the rear diff is locked, both ABS and Multi Terrain ABS will not operate? I have operated rear diff lock with MTS and seen others do it in various UTUBE videos. Is this a typo ? Has anyone used rear diff lock with MTS before?

 

This post on another forum says you can use both together with some caveats:

 

Is this your manual?

 

Yes, I referenced it in the first post. That’s why I have the question. I have driven my ORP with MTS on and rear diff locked. But the manual implies the MTS ABS won’t work. I don’t see how MTS works with no ABS?
