Newer Owner Question
I have an 016 C459 AMG and have owned it now for about 10 weeks. It has 50 thou (km), about 32K miles...Normal driving and on the front display I have seen a red warning triangle appear twice. It has come on and went off so fast there has not been enough time to recognize what its trying to tell me. The car has been in comfort mode, and it has had zero impact on anything that I can see or feel..Everything seems perfectly normal with absolutely nothing impacted. Would there be any code stored that I could have read? I am about an hour away from my dealer and wondering if I should drop by and have it scanned. If anyone else has had this experience..Thanks

What the distance warning light means
When this light is illuminated, it indicates that the computer has detected an object in the road ahead of you that is approaching quickly. This may not always be a car and could be a large object in the road. Keep your eyes peeled for anything on the ground if there are no cars ahead of you. Once you have slowed down or gone past the object, the light should go out.Keep in mind that this system doesn’t look only at distance, rather it looks at how quickly you are approaching an object in front of you. Even if the car ahead is a good distance away, you should still slow down as they are most likely moving slower than you.
Typically, there are separate warning lights to indicate that an issue has been detected. A common fault with these systems is a blocked sensor. Dirt and debris stuck to the front of the car can inhibit the sensors ability to see and the system will be deactivated temporarily. Clean off the front of the car and everything should return to normal. If cleaning the car doesn’t help, get help from a qualified technician to identify the problem using a diagnostic scan tool and fix it.

I get this regularly when I'm driving a little more aggressively in traffic. If I see a car turning and know I'll make it, when I start getting close this alarm goes crazy. Also doesn't like me zooming out of the the parking garage at work.

may be the active collision prevention? there is a sensor (probably a Doppler radar) in front of C43 that measures your speed with respect to the object in front of you and warns you if you get too close.

If, however, you're approaching far too closely on an object (moving or stationary) it will do the visual, audible, and depending on how close you get, will activate the appropriate ABA (Active Brake Assist) stage.
In what country are you located?

Lots of info about everyone's experiences with this..Thanks a ton for sharing, sounds like something to get used to over time. Thats a hell of a lot better than looking for something to repair

It goes off in two stages - first is just the visual warning, the triangle comes on, if you keep getting closer or the car in front of you suddenly brakes, it will flash and an audible ping will alert you. If your car has presafe and you continue doing nothing, the car will tighten the seat belts (quite significantly) and slam on the brakes.
Just after I got mine, my stepdad (who drives like a maniac) was taking it for a test drive on the motorway and was driving WAY to close. The guy in front of him brake checked himmand the car yanked us into the seats and slammed on the brakes! After that he drive a lot nicer
