Well, "should and could" seem to be two different things! The lights were adjusted way too low when I purchased the ES back in Sept. '15 so, I had the dealership adjust them within a couple of weeks of delivery of the car but, then, they were way too high and I got lots of "flashing to dim them every time I drove it at night!
I took it back a second time and they supposedly adjusted them again and were supposed to be "perfectly adjusted" according to them.
They are still adjusted too high and I just do not want to take it back to them for it if I can do it myself.
By the way, I am not sure what you mean by only having "Startup" leveling on my '08 as they would continually self-adjust" as I drove the car. I am sure of that as it was easy to see it happening. I, also had to adjust these up a little bit (Startup level I guess) and were easy to adjust but, I cannot figure out how the new ones adjust.The '08 also had the lights (HID) that would illuminate the turns and all was great, even when I sold it just before buying the 2016 ES350.
The dealership even had me come back to the service bay area when they finished the last adjustment to show me they were supposedly adjusted right! NOPE, still too high
I guess on my next service visit (10K oil change) I'll just have to complain again as I still get occasional flashing by oncoming cars.
