HID Headlight Aiming

[OneFunGenesis]

Yea, I did mine as well. On my last car, I hand built my projector headlights...so these lights are terrible to me. I really need to replace the bulb...it's hard to see at night unless it's pitch black outside.

The minute I drove this car at night, I knew the lights were WAY too low. Had to be fixed immediately

Had mine for 3 weeks now, tonight was the first time really driving it in the dark. My wife was driving and she even noticed it wasn't lighting up down the road (she drives a Subie Tribeca with projectors). It's definitely too low, probably only lit ~150' down the road. Guess I know what I'll be doing in the morning now

 

[snork]

Went and raised them this morning. Followed jonah's instructions in the OP. I think you need a proprietary tool to actually use the factory UP-DOWN adjustment. I used a 9" long 3/16" flat screw driver (you'll need at least 8" long screwdriver and 3/16" or smaller blade, the blade was about as big as will fit). I spun the gear towards the front of the headlight assembly like jonah mentioned, it is clockwise and needed about 2-3 full revolutions to raise it up an inch or so at about 9' from my wall. Hopefully that should do to trick

With the AFLS, if I'm reading it all correctly there's a sensor located on each of the rear shock towers that tell the system where to aim the headlights so they stay the same regardless of the load in the back of the car....is this correct?

I thought the lights also kept themselves aiming the same distance at the ground when you were going over bumps or up/down hills etc. but this doesn't seem to be the case, that or mine aren't working correctly. When I was going over a "speed hump" I came to a stop with the front wheels on the incline of the hump and my lights shot off into the air, stayed still on the hump for at least 5+ seconds but the lights never leveled back out to the road or moved at all for that matter. When I start the car each morning the lights go through their entire self check.



This is what it says from Hyundai's site about the AFLS system:


AFLS equipped (HID lighting system):
The headlamps matches light distribution with the vehicle's turning angle so that upcoming curves and intersections receive maximum illumination. The headlamp leveling system keeps the illumination parallel to the road surface regardless of the vehicle's tilt.


Thanks in advance for the replies



Found the answer to my own question I think lol. I'm going to take it that leveling system used in our Genesis is Static based on the information provided via the sensors on each axle which adjusts only for vehicle load and not a Dynamic system that also compensates for bumps, acceleration/braking etc.

 

[snork]

Yep, the ALFS only sets the vertical aim when the headlights are first turned on. So if you have a heavy load in the trunk or back seat (ie: the rear is low) it will adjust for that accordingly.

However, by turning the aim adjustment gears, you are adjusting the entire housing. So even if it senses tilt of the car, it will still end up being higher than before because you've now manually raised the center/level/horizontal position.

What did you all do when turning the gear that jonah described above (pushed it with the screwdriver blade / turned the screwdriver (circular motion) / what to get the gear to turn)?

I've currently got the plastic shroud off, but no joy on getting the gear to turn. WAY too much force required to even move it one click over, much less getting the gear turned over several times for the correct adjustment? I'm going to give it one more go, but I think this vehicle is going to have to go a dealer-unfortunately. FYI, our problem isn't that the HID low beam is too low...but it is way too high. I've noticed it for a quite a while compared to my FX...a few too many people flashing high beams at my spouse also has her convinced that it is too high. :/

 

[snork]

It takes a bit of force, but it should roll over. It wasn't "fun" adjusting mine spinning it ONE cog at a time. Took a bit of patience, mine were really low, and I ended up doing it twice I've since been stuck in traffic on the highway next to some other cars with factory projectors (BMWs, Infinities, Lexus, etc.) and mine look to be just about even with other cars now.

I found the easiest way is to be sure you are using a screwdriver with a small enough head (gave me an excuse to go out and buy a set of new Craftsman screwdrivers). Then I put the screwdriver down in the hole "vertically" and rotated it 90 degrees to spin it over one cog. Be sure to stick the blade into the notch of "V" so that it pushes on the meatier part of the cog so you don't bend them (they are only plastic). Once it got moving, I also pushed the blade in the direction of the spinning to get another 1/4-1/2 cogs worth of rotation.

Since you want to actually move them down, you'll need to spin the gear counter-clockwise/to-the-left when looking at it straight down.

Snork,

Okay, mine isn't liking me. Put a bend in a screwdriver tonight trying to work it...that is when I called it off before I made a costly mistake. I tried both twisting in the cog and 'pushing' the cog counter clockwise. More force than should be needed was being required.

On the 90 degree twist...was one portion of the screwdriver head 'braced' against something to gain purchase when you twisted against the cog? Or a simple twist of the hand / screwdriver is all that was required.

Because my technique obviously wasn't up to par tonight.

 

[OneFunGenesis]

It should be just a simple twist. I have found that if you are doing it with the engine ON you are FIGHTING the auto level system. Adjust the headlights with the engine off but the accessories on. It should require less force to move the light

That could be. I had mine off with just accessory power on to see the headlight cutoff on my garage door. It was definitely only hand twisting of the screw driver.

I have a different issue. Took mine in to the dealer today to have my driver's side high beam lowered. When projected on my garage door it's several inches higher than the left side. The tech fiddled with it for awhile then told me he had lowered it as far as it would go and although there's considerable improvement, the two high beams still won't quite line up. I find it difficult to understand why the left won't align the same as the right and wonder if the tech really knew what he was doing. Has anyone out there had this experience before? Can anyone explain how to raise or lower the high beam?

 

[snork]

Retry...the high beams are standard halogen reflector style lamps. If the high beam really is the only problem, the lamp might not be seated correctly in the housing. That would be the first thing to check relatively easily.

That's an idea, I'll check that. I'd still be interested to know where the high beam adjustment is and how to get to it.

Snork, just looking at it from the front, it would appear to be identical to the left. It looks perfectly straight.

 

[QuantumRift]

Well, we've had our 2012 3.8 over a year and a half, and yea, I notice that the HIDs have a definite 'cut off' that, when I'm doing 80 mph, I'm overdriving. So I'll be checking out the headlight aiming if I don't have it adjusted at Hyundai service shop.

 

[Philth]

I've noticed that my driver's side is a tad lower than the right (a bit more difficult to see at night on the left side), though the Hyundai repair manual says they should both be level with each other.

My car is exactly a year old today. I wonder if the dealer will take a look and adjust them to be level with each other?

 

[Philth]

I'm at the dealer now and they tell me that my car is 15 days past the one year adjustment warranty. Trying to charge me $95 to aim my headlights. Haha. 0_o

On the phone with Cust Service now.

 

[OneFunGenesis]

^ Lmao, wut?!

 

[Philth]

They didn't charge me. Not sure if cust. service got back to them that quick, or if it was the fact that I was telling them that I was going to discuss with cust service.

I'll have to check the aiming when I get home this afternoon. They did indicate that the left headlight was adjusted. I would have done it myself, but from what I read, it looks like error codes for the AFLS are produced when adjustments are made???

 

[OneFunGenesis]

I adjusted mine myself and didn't have any error codes from AFLS....
