For short periods of time I personally wouldn't worry about it. If you are going to store it for a few weeks or more, you mite as well run it up on the jacks. It will take the weight off the tires and suspension, also up in the air no one can just hook up and take it.
My parents brand new 5er has the auto leveling system. They bought it in October took it on a trip to Arkansas then brought it back up and dad parked it in his shop for the winter. It has been ran up on the jacks with all 4 tires 2" off the ground since November.
