When 4WD is disabled it engages a "low" vacuum level and holds it for 30-seconds, then removes vacuum. I've hooked up a vacuum gauge and watched it work.

The 30-seconds is basically holding the pen button "down" giving it enough time for things to engage. Mine engages almost instantly once vacuum is engaged (at least with the front wheels off the ground in my garage).

Nice as you don't have to worry about the hubs disengaging once they are locked in if you loose vacuum for some reason.
