ML cornering lights
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 ?

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.
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)








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




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 ?








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.
