When you first put the shifter to the M (manual) position at highway speed, the DIC simply shows S for Sport mode, no downshift occurs as with my 350Z. As soon as you downshift, it displays S5, S4, etc., but will only drop to 2nd gear, unless you hit the "-" tapshift button when stopped. The manual says, "A 1st gear start can be selected by using the Tap Shift controls on V8 models." See section 8 page 29.
