[EightmanVT]

I don't think it is supposed to show up but I may be incorrect. I had it in Auto during our 1' of snow last week and it never displayed "4WD" but it did indicate "Slip" a few times but it performed like a champ.

As you probably know...but others may not...the "Slip" indication is normal. It occurs when traction is lost and power is being direct to other wheels....

The only thing I don't like about it...is that it reduces power too much...rather than transfer existing desired power .... it can bog you down a bit...till you let off the gas.....

Try it out in the snow... and then turn VDC off...much more fun to drive that way....
