Oh - I was thinking the hiding places in the basement would allow him to escape. If that's not the case and he bolts for cover, just act like he's out with you. Talk like its a normal thing and he should get the idea.
If this is the place he'll be spending time in furure, he might as well get used to it. If he can't get hurt or escape from the hiding places, he should be fine using them.
