Both the '98 Grand Prix and the '97 Grand Am have daytime running lamps, so the headlights are always on. In both cars, it seems to happen more after it's been sitting awhile and its cold. Again, I don't think it's a big deal (at lest, not in our two cars) but I think it's funny that it's telling me I have CD in the cassette deck.
I don't yet have an owner's manual for this car, but one I purchased on ebay

The site's down right now, so I can't give you the link to your specific manual, but that's where I downloaded my copy.
