IIRC, isn't there a 'problem' (feature) with one of the switches the the right of the steering wheel, that results in this apparent wrong behavior? Have a search on this site for the experience of others. It is on page 3-57 of the owners' manual, under DIC controls. The second button down is 'interior lights' and pushing it causes the interior lights to behave in a way many owners don't seem to get along with.The courtesy lites on the mirror will not turn off with the switches. Any ideas?
