Return To Home on lighting panel ?

[Keff]

Hi,
We have just purchased a T61 Campervan & have a Return To Home function on the lighting panel, you can turn this on or off but it doesn't seem to really do anything.
Anyone know what this actually does ?
Many Thanks. Keff

Ours is a T5.1. Will only work if headlight dial is set to ‘auto’, and needs to be dark.
