Your drivers manual will have the expected results for each switch setting.
If you don't have the manual let me know and I'll go make a copy of mine (lighting function page).
IIRC - Two manual "on" settings, one auto on/off with fade off feature setting triggered by opening and closing the door, and an "always off" setting.
