When I put my jeep commander on drive the letter D turn into a number 4 why

D is your final drive & 4th high gear. When in D your trans shifts automatically 1 thru 4. When the gear selector is in 1, 2, or 3, it stays in that gear & does not shift automatically. Like for mud & snow, off-roading, hillclimb, or steep desent.

is it in tow haul mode
