Default Need Help with an issue in my IS (headlight autoleveling)

I changed out the bulbs on my car and decided to raise my passenger headlight with the screw thats on the headlight. Everything worked out great except that when I turned my car on later that night the auto leveling on my car pointed the passenger side headlight downwards. I think it did this because when i was adjusting the headlight my car was parked in my driveway which was on an incline so when i put it on level surface i guess the auto leveling kicked in and pointed the light downward. So my question is how to fix this i tried adjusting it through the screws but the light wont move at all. Is there a master reset for the auto leveling so that it can go back to normal or what can i do since i really hate having one light pointing into the road

Not necessarily free. If owner has monkeyed around with the standard settings they may well charge to fix what was messed up. Be prepared and ask questions beforehand.

drive to somewhere flat. turn on headlights against a wall, then adjust until both sides are even.

I doubt i broke it, since the auto leveling still works everytime i turn the car on the light goes up then goes down again i think i just need to figure how to reset the autoleveling and if you dont have better advice than " you broke it your screwed " i would appreciate it if you just kept it to yourself.

1. afaik there is no "master reset" for the auto-leveling headlights.

2. playing around with the headlight level adjustment while not on a level surface and not against a wall with reference points (horizontal/vertical lines) will lead to undesireable results. that much should have been obvious to you prior to making adjustments, but hindsight is 20/20.

3. if you tried to adjust your headlights on a level surface and against a wall with reference points but still could not get the headlights to aim properly, it's time to bring your 2is into the authorized service center. according to the owner's manual (ver. 2006):

"If the error is over the value specified above (referring to the number of turns in the same direction), take the vehicle to your Lexus dealer to adjust the headlight aim." p.313
my guess is that turned the adjustment screws too far probably broke something.
