Forgive me but I have to ask. you checked the owner's manual?
reason I ask, is at least on my R171 2009, on is off and off is on (at least to me) when using/setting the choices. also, if checking lights in open (daylight streaming in) garage, you won't see anything because the system does not put them on in daylight.
