Every once in a while mine disapears. I am not sure why but like Dave67 mentioned just hit the + or - on the shifter and it comes back. I swear its after my wife drives it, but she says that she doesnt mess with anything...

Just found this thread. Saved my from insanity as I tried to figure out where my light went occasionally, and then what I had done to get it back. Here I was thinking I had a short somewhere as I fumbled around with shifter and the gear lights returned. LOL
Learned this lesson when shifting manually without selecting "M" first with the transmission lever. Interestingly, the + and - rocker on the shift lever will also shift the transmission manually without moving the transmission lever into M first. The gear indicator goes blank when pressing + while in 6 and returns when pressing - .
I use the manual shift feature often to hold in 5 when driving curvy roads. The Tow Haul button holds shift points longer and provides aggressive downshifts when braking. Very useful up and down grades, but took some getting used to.

I think you will find if you check your manual, you are not "shifting" the transmission with that button when you are in drive, but are instead 'removing' higher level gears from the transmission's automatic selection. If you sit at idle in drive and press "-" once, you convert the transmission into a 5 speed. Press it again, and its a 4 speed. You'll see the display change. If you are driving and in 6th gear, pressing the "-" will 'remove' 6th gear from the display, and the trans will of course downshift into it's now highest gear, 5th. Press "-" again, and you'll downshift into 4th because you just "removed" 5th gear. Pressing the "+" button adds the gears back for automatic selection. A really neat feature!
