Jopopsy, the Bigfoot levelers only action is to sound an alarm. At no point do they retract on their own. An alarm goes off when the key is turned on and that's it. Shifting into gear with or without the ebrake makes no difference. So in other words, you can attempt to drive away with the levelers deployed.
