Has anyone heard if cornering lights can be enabled on the 2102/2013 ML's ?
The bi xenon lamps seem to have the same internal fittings as other mercedes models with the cornering lamps.....
The ordering guide includes them, so does the owners manual, yet they are inoperative....
Any comment on this issue ?

Mine work; are you sure yours are not? No activation should be required except as follows:

The cornering light function improves the illumination of the road over a wide angle in the direction you are turning, enabling better visibility in tight bends, for example. It can only be activated when the dipped-beam headlamps are switched on.

Active:
- if you are driving at speeds below 40 km/h and the turn signal is activated or the steering wheel is turned.

- if you are driving at speeds between 40 km/h and 70 km/h and turn the steering wheel.

Not active: if you are driving at speeds above 40 km/h or switch off the turn signal or turn the steering wheel to the straight-ahead position.

The cornering lamp may remain lit for a short time, but is automatically switched off after no more than three minutes.

Thanks for your detailed input Greg
However, as I also have a 2011 E550, i am familiar with the functioning of the cornering lights, and thats why i became aware of their absence on my ML, experiencing no illumination when turning into my driveway....
Unless its a Canadian specific problem, as you say the USA ML models cornering lights do in fact work....
Can any other Canadian ML owners, with bi xenons, shed some light on this issue ?
(pardon the pun)

Mine do not work either. I have checked them earlier today and there is no lateral movement of the lights or the inside mirrors. I will call MB tomorrow morning.

GregW / Oregon

Exactly how did you check them?

mbden

Underground garage, lights on AUTO, turning steering wheel has no effect on lighting pattern. Tried flashers, no effect.

I take back my statement that mine work - now I'm not sure without further testing. I may be remembering my recently departed W164 that used the separate fog lights for cornering. I'm beginning to wonder if our NA ones are dumbed down. Here's what the international manual says about the Intelligent Lighting System.

"Switching the Intelligent Light System on/off

Press the or button on the steering wheel to select the Settings menu.

Press the or button to select the Light submenu.

Press to confirm.

Press or to select the Intelligent Light System function.

If the Intelligent Light System function has been switched on, the cone of light and the symbol in the multifunction display are shown in red.

Press the button to save the setting.

When you activate Intelligent Light System, you activate the following functions:

- motorway mode
- active light function
- cornering light function
- extended range foglamps
- off-road lights"

My car does not have a function to activiate the Intelligent Light System, only Adaptive High Beam Assist. That could be just a different nomenclature for the same thing, though the light lenses themselves have the former title. I also wonder if we get the fog lights. A couple things to note: The left stalk needs to be pushed forward for AHBA to work, even if activated in the menu; also, you may need to be moving for some of these to work. Curious.

I wondered too checking in morning.

I called MB today and frankly, they were not very useful. The technician did not seem to know much of the bi-xenon lights and was under the impression that the only built-in feature is the auto high/low beam. They suggest that I drop by the dealership so they could have a look at it! WTF, I am not sure I want these clowns around my car, maybe I should send a line to MB Canada directly to find out. I just hope they provide more details without sending me back to the dealership!

I am convinced that something is not properly activated for the bi-xenon to fully operate as advertized on MB site.

mbden

I will be really upset if it turns out these Bi-Xenon lights I have been waiting for one year to be on my new truck are not "Intelligent".

dougiebear

Definately my CAN lights are adapting intelligently seemed like fogs tonight too. NO freakin corners though. Got reflecter and seems to be a bulb behind a plastic shield. We don't have the Mbrace2 head unit either am I TICKED or what for a Grand we got pretty ML graphic with no adjustments for times that's it. I want cash or I want Mbrace2

GTscrub

Wait, so the Canada MY13 don't have MBRACE2? That's really lame. I test drove the MY12 550 that's fully loaded and didn't get it mainly because it didn't have MBRACE2/Apps.

dougiebear

Appearantly since May 8th email sent. Mine was already ordered. Was never told this I would have not accepted without a better deal.

GregW / Oregon

Both 2012 and 13 materials describe the Lighting package as having Active Curve AND cornering lights. No mention of fogs.

dougiebear

Fog adaptation.
Its shown in videos. I think on US site too.
Dipped and wider

roger23

The ML owners manual specifically talks about cornering lights. (but does not mention fog lights.)....
In fact, the owners manual even discusses the error message you will receive if the cornering light bulbs are burned out or not working....
I emailed MB Canada and asked about the non working cornering lights.....
The answer i received that 'cornering lights' means "the active bi xenons that swivel when you turn corners...."
Since i have an 2010 E550 with active bi xenons AND cornering lights, i do know the difference.....
If MB canada does not know the answer, why dont they tell me that, rather than some ridiculously lame answer that they seemingly would expect me to believe. ?
I emailed them back, asked them to return to the drawing board, and give me the REAL answer, not something they hope i would believe.....
Has anyone tried contacting someone / an engineer at the Tuscaloosa assembly plant regarding this issue ?

GregW / Oregon

Maybe you have to be moving. In my driveway turning on the rear fog light, which is supposed to activate the front fog pattern, has no influence on the headlight beam pattern.

GregW / Oregon

Where do you find that reference in the manual?

nosnoop

GregW / Oregon

Is that from the 2013 manual? It's not in the 2012, at least the early one I have a PDF of.

nosnoop

Yes, 2013 Manual Edition B.

mbden

MB Canada confirmed the Bi-Xenon should have the cornering function as advertised in the owner's manual.

But in my case I dont even get the active light function while turning. I also noticed that the headlights are always symmetrical; and that appears to be related to a particular setting described in the manual. I maintain that my lights are not programmed properly.

GregW / Oregon

Note that the light switch needs to be on "Auto" for the steering function to work. For the Dynamic function to work, it needs to be activated in Settings, and the left stalk needs to be in the forward position.

mbden

Greg, I have tested it with the lights in Auto and manual. When in AUTO, I see the icon in the display with the "A" in the light symbol.

dougiebear

That's the adaptive sign for us. Mine work but it helps to be moving at a bit of speed. Although mine steer below 25km but no seperate corner lights come on and they should
