Yes there is, but I can't remember precisely how.
It's very easy though - you just park where you know the van is perfectly level and re-set the gadget using the touch panel.
If nobody else comes on with the answer I'll go to the van and work out some instructions. (I've a feeling it's quite obvious if you study the panel carefully.)
