I adjusted vertical level on driver’s side HID last night. It was pretty happy that I can see a little farther now.
But when I turned on headlamp on this morning, it was very LOW!!!!
I turned-off engine and wait….turned back on but same thing. Now I really cannot see! I felt my wife’s Sienna LTD is better because HID is more brighter+ blue and can adjust headlight level by dial while driving……..
I need to adjust it tonight again. But want to know what did I do wrong? I just turned screw clockwise….that’s all.

 

I Beleive your HID autolevler defaulted back to the being lower on the driver side for a safety reason. The driver headlight will be lower from the factory to avoid blinding the oncoming traffic. No worries, this is normal.

 

thats wierd :S, It shouldn't have moved back down if you adjusted it manually. I know a lot of people including myself when i take delivery have adjusted their headlights when they lowered their car. Hopefully they can chime in with some info.

 

Yes, it is weird that a manual adjust was overridden by the servo motors. Unfortunately, when you lower the car, you run into risks of effecting the auto-leveler and AFS in the composite headlight assembly. I believe that there was a member a while back that figured out a way to correct this. Hopefully they can offer insite.

 

Thanks guys.
Problem is lower than original now!
Actually, Dealer adjusted once when I put my car in service.
they said "Dr side is now even pa side". But I wanted to up a little more because I had black spot where I wanted to see……….. I will do again.
Hopefully, I did not screw.

 

if this works i pulled this from another post in here for the same reason. i am taking my car this week to put the springs so i saved this doc. see if this helps out!

 

Great PDF file post, I think that most people will take for granted the pre-headlight aim prep such as full tank of gas, heavye items removed from car and having a person in the dirvers seat. These are important things that will ensure having better healight aiming as the beam will need to be a bit higher.

 

Don't forget when making vertical adjustments, you have to make the same adjustments horizontally... on the OEM HID equipped cars

I have a feeling that this PDF that's been floating around is for the non-HID equipped cars... Since warning on lights and in our manual state to make both adjustments..

I wonder if one of our awesome Lexus Tech members can see if a different file exists for the AFS / HID equipped cars that properly shows both adjustments..

Glad you pointed that out Joe Z! if you would be so kind to PM me if you do find anything tonite to me. i didnt read this pdf in detail and saved it to bring with me tomorrow nite. If anyone has the correct one for the AFS/HID please post it. I want to make sure i can adjust this when they install. I found this in the post about the AFS light after lowering. info please

 

i only adjusted the vertical aim and its fine it stayed same i can see better. i thought of adjusting the horizontal but i got lazy. everything still works fine for me.
