ML cornering lights
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 low-beam
headlamps are switched on.
Active:
Rif you are driving at speeds below
25mph (40 km/h) and switch on the turn
signal or turn the steering wheel
Rif you are driving at speeds between
25mph (40 km/h) and45mph (70 km/h)
and turn the steering wheel
Not active: if your speed exceeds
25mph (40 km/h) or if you switch off the turn
signal or turn the steering wheel to the
straight-ahead position.
The cornering light function may remain lit for
a short time, but is automatically switched off
after no more than three minutes.
But have not seen it happen in person.

I just downloaded the eBrochure to check, and it is not mentioned there either. Web site info is not accurate and is prone to error due to web design being adapted from a global template.
Having the cornering light is nice, as with any extra feature. But I won't lose any sleep for not having it. I have it in my BMW, and it rarely strikes me as making any huge difference. Mercedes' headlight already has very broad coverage.
While I would probably make a big fuss if they leave out something like the bi-xenon, lighting package, active driving assist etc, I don't think I would spend too much time over the cornering light. But I suppose it could be more useful for some user than me. Just my $0.02 worth.

I just sent this email to MBUSA Owner's Support:
"The Dealer Ordering Guide for my 2012 ML350 lists cornering lights as part of the Lighting Package features. Also, the 2013 Owner's Manual details their function on page 125. However, from involvement in two ML forums it appears no one in North America has working cornering lights. You can see them, but bulbs are not there and they do not function as advertised.
What gives? This is disappointing. My W164 ML had fucntioning corneriing lights so this seems like a step backwards."

Minimizes the risk of wheels hitting the entrance curb etc...
I do agree with Greg, and as there is probably a zero chance of having the cornering lights work at this point, my main focus is to find the rationale behind the decision to have them inoperable.
Someone made that decision......why ??
Regarding 'nosnoops' previous post's comment on 'individual tire pressure readouts', in fact my 2012 ML550 has the readout showing the actual tire pressure in each wheel, as in the photo above...
This tire readout display is only available with the 21" AMG wheel/summer tires option, which i ordered, and have on my ML
Its actually very handy, not having to check each tire with a pressure guage, just to check for any tire pressure variance....
TECH at MB says they are sufficeticated not simple.
I think the light is supposed to turn into the reflector but its not working. Will see about software mods
My ML550 is almost here, am hoping to take delivery next week. I'll post back then if the cornering lights work the same as a W221...
The tech is probably thinking about the adaptive head light which is a totally different thing.
Am I on the right track ?
Does the light beam from the bixenon point inward and down into the reflector which then casts light to the roadside in the direction of steering? I believe It should stay that way for a few seconds as the wheels turn straight

Initially the puddle lights in our 2012 ml350 along with a bunch of early releases didn't have these activated and wouldn't turn on until a software update

The cornering light function utilizes additional reflectors integrated in the headlamps. It is controlled on the basis of data on road speed, steering angle and indicator position.
Using this data, the control unit ensures correct implementation of the cornering light function in different scenarios: at junctions, roundabouts and even when reversing.
The intelligent electronics system does not switch the cornering lights on and off abruptly. Instead they are faded up and down using a dimmer function. This gives the driver time to adapt to changes in lighting.
An ML with Bi-Xenon lights
OR
Low beam bi-xenon headlamps illuminate roadsides more clearly and broadly than conventional lamps, and their high beams have a significantly longer range. This enhances perceptual safety and allows you to drive much more safely at night.
In addition, when cornering sharply at speeds of up to 40 km/h, the cornering light function of the bi-xenon system activates, ensuring much better illumination of the road.
The term "bi-xenon" means that low and high beams utilize the same light source. When the high beams are engaged, maximum brightness is made available. This extends visibility and enables headlamp flashing.
In bi-xenon low-beam mode, the concentrated high-beam light is partially blocked through the insertion of a shade. Bi-xenon low beams shine much more brightly than conventional halogen low beam headlamps, enabling drivers to identify roadside objects more rapidly.
The system also includes dynamic sensor-controlled headlamp range adjustment that automatically compensates for vehicle position changes caused by braking, accelerating, or a payload. High-powered bi-xenon gas-discharge headlamps also rarely dazzle oncoming drivers.

Ditto ... checked this out at our dealer today ... no bulb in the active corner spot. dealer confirmed that the Lighting Package comes with "Active Curve Illumination" and "Adaptive Highbeam Assist" but not the active corner. (this in the US)
