The seat should have: front-up/down, back-up/down, seat bottom-
forward/back, seat back-forward/back. Usually the bottom controls get
"sticky"--the seat back control cable stretches and disengages from the
drive at the hinge.
The Volvo VST can reset the seat motor potentiometers (Pre-OBDII). To
set the memeory buttons adjust the seat to the position you desire and
hold the MEM button down while depressing 1, 2, or 3.
The goal when driving is to miss the maximum number of objects.
