Do the headlights turn when you turn the wheel in a Genesis

 

[Canuck Genesis V8]

I have a V8 Tech Pkg. On this model, I know they swivel and autolevel.

thanks for the response I went to a dealer and sat in a v8 with tech package with lights on and turned the wheel and the lights did not turn but did level

I believe the auto-leveling system is sensitive to the steering wheel position as well as the speed of the car. If the car is stationary, the lights won't turn.

One cool thing to watch is when you have the car running (to be simple here) and then turn the lights on, you'll see them 'register' themselves left/right and up/down. I love to show that to people It makes them laugh.

thanks JO but if the car is rolling and you turn a corner the headlights turn dont they

Yes, how much it turn depends how fast your are driving.

Headlights with AFLS definitely move side to side when turning. The movement is very obvious to me - and my passengers - on the street where I live, as I'm going pretty slow (<25 mph) and moving the wheel constantly due to curves and cars parked on the street. It's kind of hypnotic, actually.

If memory serves, the owners manual said that the "inside" light (e.g. the right side if you're turning right) moves 7 degrees, and the outside light moves 15 degrees. The lights don't move if you turn the wheel while the car is stationary.

I am curious that a number of owners reported they can get the headlights to move left/right and up/down. I have the AFLS on my Gen but have never seen it move that way.
Do you have to get the car moving and then turn the headlight on to see that? I tried this but it didn't move. Can you get it to put on the "lightshow" with the engine running, trans in Park. Better yet, tell us the sequence of steps to get the lights to move.

Get in the garage when its fairly dark and start your car. When the lights come on, and I mean JUST as they come on, they'll "do the dance". You have to be near enough to the wall to see the lights clearly, and it only takes a couple of seconds.

I've seen my headlights do this little start-up sequence, too, but not every time. FWIW, my 530i also did the vertical version of this, but not every time. I can only speculate that it's more likely to do it if the lights haven't been on for a while (e.g. first turn-on of the day?), or perhaps if a sensor perceives that the load has changed. In other words, I'm less likely to see "the dance" if I turn my lights back on just a short while after they were on previously. But...I'm only guessing. Perhaps our documentation expert (aka Ric) can plumb the depths of HMA documentation and uncover the facts.

the last car that i had that had HIDs, you had to turn the lights on before you started or immediatly after starting. depending on when you caught it in the start up sequence it would partially be through the leveling. so i think it does it every time, you just may not see it doing it. otherswise your lights would be out of whack when you turn them on while driving.

The calibration is done when you start the car, and not when you turn on the lights. So to see it they must be on immediately after starting the engine.

Nothing in there about calibration or self-test modes, only stuff the dealers can test/calibrate with their laptop connected. However, trolling through this swamp produced a revelation not mention here before. In the repair procedure you have to tell the laptop whether the car has AIR SUSPENSION , or not. I assume this is the Korean version of the car which also has the cooled front passenger seat, etc. But AIR SUSPENSION tells me there must be a console switch where you can select ride characteristics. How many of you have been waiting for that gem. If the car has air suspension, there are 4 sensors for the height adjustment on the lights. Our version of the car only has two.

Description Adaptive Front-lighting System (AFLS)

AFLS(Adaptive Front-lighting System）is a headlamp orientation control system that takes into account both steering angle and vehicle speed to orient the headlamps to an angle that provides better nighttime visibility.
Variable conditions make beam pattern of running vehicle kaleidoscope.

Component of AFLS

1.Input part : It is provided that information of speed sensor, height sensor and so on related to condition of vehicle.
2.Control part (AFLS Unit) : It controls Output part by analyzing/judging Input signal.
3.Output part : It drive Low beam of H/Lamp to upper/lower and left/right side optimum beam pattern according to output control signal of AFLS Unit.
Main function of AFLS

Content Description
1 Dynamic Bending (Swivelling)
• Providing optimum beam pattern in the curve road
1.Enhanced visibility in the curve road
2.Drive Low beam to left / right side

2 Automatic Leveling (Leveling)
• Compensating Low beam according to inclination of vehicle
1.Compensation according to static condition (Load)
2.Compensation according to dynamic condtion (Quick start, Sudden stop )

3 Fail-safe
• Fail-safe reaction while detecting system failure and malfunction
1.Detecting signal / communication error for Swivelling
2.Detecting signal /communication error for Leveling
3.Detecting system failure

Advantage of AFLS

Content Description
1 Enhanced stability
• Visibility Guarantee In case of curve road
• According to vehicle Speed/Steering angle, speed/angle of Swivel actuator is automatically controlled to provide optimum beam pattern
• Fail-safe reaction application for Driver on opposite side road
→In case error communication,automatically return initial position of Swivel actuator

2 Enhanced convenience
• AFLS operating application by driver's selection(AFLS Off switch)
• Providing Diagnostic function for detecting system failure and malfunction and check up data information (by using Diagnostic equipment )
• Reduced wiring-harness by Applying CAN/LIN communication in vehicle
• Fun Driving Function : Swivelling of Low beam
→ Increasing driver's pride [I love this part ] [ROFL, ROFL thinking of you guys watching the beams jump around on the garage wall]

WASN'T THAT JUST MORE THAN YOU NEEDED TO KNOW?

But AIR SUSPENSION tells me there must be a console switch where you can select ride characteristics. How many of you have been waiting for that gem.

i remember seeing it as a menu option on the info screen, taken from one of the overseas cars.....i think it was on the middle eastern website.

 

[GS300rich]

air suspension would be so nice. You could adjust the height to your driving habits and road conditions, what's better than that

OK, here is how my AFLS operates. Correct or not.

1. The Self Leveling only operates when the headlights are set to Auto, and I start the car. The Self Leveling does not operate when the headlights are first in the off position, then after starting the car, I switch the headlights to on. Note that the owners manual does not differenciate between the headlights set to Auto or turning them on from off. All it says it that they should self level when the headlights go on.

2. I never notice the headlights "Swivel" side to side. Don't matter if I'm sitting still, or going very slow, they do not swivel. Seems to me that they should swivel when going slow, not when going faster. (Lincoln adverts show them going side to side when standing still).
Sometimes,,,,,,, and it may just be my imagination, only when I have my turn signal on, and going slightly faster than "slow" (not at standstill) they MAY swivel, but I may be seeing what I want to see. (may just be something not plugged in).

Don't know if I should bring this up with my Service Department, as they may screw it up, (you know how service departments are) and I can live with it as is, not going side to side.

Headlights will auto level when vehicle is turned on, regardless of whether the lights are on or not... the AFLS will only operate based on wheel speed and will NOT operate at slow speeds like less than 10-15 mph. AFAIK, all AFLS type systems operate the same way... In that Lincoln ad, did you notice that they were not showing the vehicle in motion? Chances are it was on a Dyno or something to shoot the lights moving for the coolness effect.

 

[lward1317]

I have 3.8 with Tech pack and fancy headlights that dance and do great job except that they seem to be aimed too low. Bayway Ric, I note in your detailed response earlier related to air suspension that "there are 4 sensors for the height adjustment on the lights. Our version of the car only has two." Does this mean that the self leveling position can be adjusted up or down? Does anyone know if the self-leveled position can be adjusted? Thanks.

Slow speeds are when you need the lights to pivot the most, like when going around a corner. When you are moving faster, you do not move the steering wheel very much off center. Don't matter as it is a minor thing for me.

As for the auto level. It only does this when I start the car up and the headlight switch is in AUTO. If I start car up, and then turn on the headlights, they do not auto level. Also not a big deal for me, however tomorrow when I get the oil changed, I will get dealer to check it out and if it is something simple, like a plug not plugged in, I'll let them correct it. If it is complicated, I will get it taken care of after I return from my April trip.
