GSTRANCE

So, everybody may already know this, and I could just be an idiot, but I was waiting in my car('00 GS400) for a friend , and while doing so, I was fiddling with the **** to control the position of the steering wheel.It was at its lowest point and I kept clicking the switch down for some strange reason, after about 5 or 6 clicks the wheel moved down and extra few centimeters.I thought this was just a freak occurance so I tried it on my friend LX470 and the same thing happened, whats the deal with this, anyone know?
