What is the LL mark on my engine oil dipstick for a 2010 Tribeca?

Photo did not load with question so it is attached here.

I don't know but it looks like a quart and a half low , LL may be liter low ? ?

I suspect it is the "Low Level" indication mark and you need to add oil to raise it to the "Operating Range" mark aove it.

I "suspected" it means Low Level but was hoping more actually have the same markings or at least a mention of such in their owner manuals. Guess it remains a Subaru mystery?
