For safety, wait for that final beep, and the screen to tell you "Success", before approaching the 5th. The operation is usually quite quick, but there can be several seconds between adjustments that a rookie might confuse with it being done. Just wait for the beep. You will be an "expert" after the first auto leveling.
Edit: I was watching this
video on manually using the level system. I don't know if things have changed, but with my system on my '11, you don't have to go through the process of going to "manual" on the panel to get the front legs to extend or retract. Just turn on the system, push front to extend the legs; push retract then front to retract the front legs.
Then again, there is the "error
dispalys" on that video too. LOL
