Need help aligning the headlights in my 2013 Frontier
 

I have looked in my owner's manual, online and done a search in this forum for information on how to align the headlights in my 2013 Frontier. I have also looked at the units and did not see any adjustment points as well. I have always been able to adjust the height of the beams on every other vehicle I have had but cannot seem to do it on my Frontier. They are just too high and do not illuminate the road well enough on low or high beam. Any advice/help offered here will be appreciated.
