2018 Suburban horizontal headlight adjustment?
 

I just purchased a 2018 Suburban. We figured out the vertical headlight adjustment but cannot find a horizontal adjustment. The headlight on the passenger side does not shine on the shoulder at all - it’s completely dark on the passenger side beyond the side of the vehicle. It’s troublesome to make a right hand turn on a dark road because I can’t see anything on that side. Can’t see the ditch, curb, signs, trees or anything else that might be there and I certainly can’t see the wildlife in the ditch.

The graphic shows headlight beams should extend from the passenger side towards the shoulder a bit. Where I have colored it yellow, I don’t have any light.

How can this be corrected?
