Not sure where the adjustments are, but I would take it to the dealer for aiming. My guess is they may be right and you're just not used to the sharp cutoffs required to prevent blinding of oncoming traffic with these newer bright led lights. You'll also notice that the driver's side has a slightly lower cutoff than the passenger side, which is normal. How are they on high beams? You shouldn't have issues when you are using the high beams on rural roads. The dealer should have an aiming screen to check them for alignment.
We don't have that. (Or at least I don't and the manual doesn't show it) Three of those buttons we do have and are together on the left side of the steering wheel, in that respect similar. No adjustment for lights.
North American safety regulations do not allow manually (driver) adjustable headlights anymore. They require auto-levelling headlights for HID/LED headlights which use ride height sensors to adjust the headlights. If your baseline setting is off, auto levelling or manual levelling won't help you. Max height is "normal height" the lower settings are supposed to be used when you have more weight in the back or towing.
Since most people will not adjust their headlights on their own, auto-levelling makes sure you're not blinding everyone. Auto-levelling costs more which is why they only put it where mandated by law.
I find my SEL headlights to be disappointing, but I still get flashed as if they're too high. I wonder if it's just the reflector lights instead of going with nicer projector housings like the Limited trim.
Never seen an adjuster like that in the US, cool feature!
