How to adjust Xenon headlight beam height ?

[bgoreta1]

I have stock xenon headlights on CX7 2012 diesel. They are set pretty low so when driving on the highway I don't see as far as I'd like. How do I adjust the height of the xenon light beams ? I have taken off the mud guard to gain access from this side too. I can take a look at it by opening the hood also but I just can't find anything in there to adjust height. I don't have an adjuster knob inside car.
