Our '07 Journey has like switches in the same places as yours. Our owners manual says they are a convenience, should you desire to operate and observe at the same time.
Way back when, having an inquiring mind, I leveled and stored from each of the stations. They leveled/stored as advertised. However, ours does not allow for discrete adjustment of individual jack pairs. Given that, they have no utility for me and since remain unused.
Although my levelers are are tweaked to spec -- by myself, and once by a "professional", I prefer to ignore the auto level function. I believe it over extends the jacks. My experience has been that the system keeps looking for "perfect", and in so doing gradually over extends. My conceit is that I level faster from the driver's station, and with minimal jack extension, by observing the panel lights and adjusting pairs until my bubble level is satisfied. (And, I have all four jacks at least kissing the dirt.)
Enjoy your Adventurer! Try all the systems! We are all different, you may find that, contrary to our response above, that you find utility in those extra leveling stations.
