On the top of the headlight housing there is an adjusting screw right between the high beam and low beam bulbs. The screw adjusts both high and low beams at the same time; it's not possible to adjust them individually.
The adjusting screw is right under the railing that runs over the housing. There is a rubber bump to protect the hood, and right next to it there's a whole in the railing. The adjusting screw is right underneath it. The adjusting screw is like a gear on one side, and on the other side it has a 10mm (I think) head. You can use a screwdriver through the hole, or a socket to adjust the beams.
