Auto head lights on issue

I found out where to post, I guess. My new 06 has a automatic headlight on feature. The problem with it is that it tends to shut the headlights off to soon during the morning commute, when I consider it to still be too dark to be driving with out headlights. So I end up having to turn on the headlights again manually. Not a real big deal, but still a minor pain. Is this sensor (where ever it is) adjustable?

The sensor is below the front windshield on the passenger side. Try to make sure it in unobstructed. I have tinted windows on my 2006 Sonata LX and havent noticed a problem.
