Angry How to adjust headlights on 2012 Acadia

Our 2012 Acadia SLT headlights are set too low. Low beam does not illuminate far enough forward for safe driving. Is there an adjustment screw that can actually be reached by a human being?
Lots of stuff seems to be really hidden. I just found out last week that battery is hidden in the fender. We just bought this Acadia recently, really like it but we do a lot of night driving and these lights just don't do the job.

Someone mislead you about that. The battery is under the floor behind the front passenger seat. (Lots of other threads about batteries!! Same with headlight aiming. There are plenty of sources of information regarding the model year series of your car (2007-2012) already posted here. Learn how to search the forum!!)

Adjusting headlights without the proper positioning test equipment is not good. You can easily adjust the beams so that they are a bother to oncoming drivers.

It can be annoying to pilots of low-flying aircraft, too. LOL Remember, the low beam and high beam on each side are aligned together in one fixture.

Gotta agree, I was misled. Asked a mechanic at my oil change shop. I figured he knew more than I did where the darn battery is. I had seen the positive and negative fixtures up top for a jump start.

On where the headlight adjusters are, I did search and found no results. I guess it all depends on whether you enter the magic "right" search terms.

The post that says "pictures here" for battery location do not yield pics, at least not on my PC and browser.

The vertical adjustment screw is easy to find. It's accessible through a hole in the under hood shroud, just behind the headlight. Look in one of the holes for a screw head (either phillips, or torx). The horizontal adjuster is accessed from behind the wheel well liner. The screw is located at the outer edge of the light fixture. It's a real PITA to find and adjust.
