Mine's an '03, but the process must be similar. There is an adjustment screw above and inboard of the lamp assembly. Back it out a bit (not a lot, I imagine) to compensate for the raised nose. I had mine leveled recently and haven't changed the headlight settings. They seem OK. No one's "flashed" me yet.
On the '07 there is an adjustment screw behind the rubber flap on the inner side (closer to the radiator) of each light housing, with a t-20 ( I believe) screw. I had to adjust mine as well. It is just an up/down adjustment.
