Was on the highway this past weekend driving my wife's 2018 E300 for the first time and noticed that the blind spot detection didn't always give an audible tone when signaling with a car in my blind spot. This was a reliable feature in her 2015 E350 and works flawlessly in my 2016 C300. Has anyone else experienced this or is there something that I am missing.

I believe only the red arrows on the side mirrors come on when there's a car in your blind spot; I don't get an audible warning unless I start to change lanes when there's a car or object in a blind spot. That seems to me to be a good thing — I wouldn't want to deal with a constant barrage of audible signals on busy streets and highways.

Mine sounds an audible alarm as soon as I indicate if there's a car there

Audible beep only when using indicators.
