Fingerprint sensor
Just signed up this community to discuss and share about the W223 S-class.
Took delivery of my 2021 S450 a few months ago and there are now tons of features (especially the electronics and software options) to familiarize myself.
I have an issue with the fingerprint sensor but I cannot find anything about it in the User Manual. This does not happen each time of driving but only happened twice recently since I got this beautiful car.
Symptom:- started the car and the fingerprint sensor turned itself on (as I did not touch it or did anything that might trigger it). The 2 blue bars on each side of the sensor were lit up. An audio signal came up and sounded itself every few seconds. No warning or error messages shown on Driver display or the Main display. For the first time, it turned itself off again after driving for a while. For the second time, I drove a very short distance and it was still on when I ended my trip.
I have done nothing about this fingerprint setting since day 1 and I have not setup any personal profile. My best guess is that it is some kind of a 'friendly reminder' to setup a fingerprint profile.
Or, could this be a software glitch? Anyone has any experience with this fingerprint sensor? Can this be disabled? TIA.

Which user manual are you referring to? The printed one or the on-line manual or something else? The European on-line manual is vague on this topic but the pdf from MBUSA seems to describe it very well.

I checked both the printed one (that came with the car) as well as the pdf (downloaded from MBUSA even though my car is right hand drive as I figure this fingerprint sensor should be the same worldwide).
I used the Search function to look for ''fingerprint'' within the pdf file but nothing comes up relating to its automatically turning itself on and the continuous beeping audio.
Do you have the specific page numbers ?
PS BTW, how come this forum is W223 as the proper designation should be V223?

I am only able to answer your last question, however I will see if I can find something useful to answer your main question. The answer to your last question is that V223 is for the long wheel base. W223 is the regular wheel base (short wheel base). Based on what you provided in your profile, your S450 should be a W223.

No, V is for the long wheel base version, W for the short. Typically W is used when the model is discussed as long as the wheel base makes no difference. The same for sedan/wagon (W/S).

Perhaps you have those automatic suggestions active (cannot remember the correct name) and the fingerprint notification appears. I was referring to pages that define how a profile is created and secured with a PIN code or fingerprint. Try to do that, hopefully the message disappears.
May I ask, are you also guessing (like me) or are you sure there is such a car feature for 'automatic suggestions' (even though you cannot remember its name. But this is not important as I will definitely find it if it is there).
I myself am purely guessing it is a kind of 'friendly reminder' as this happens for many PC softwares. If you definitely know such a feature exists, then I will definitely be able to find it. I just wish not to dig for something that is not really there.
Frankly, I have no need of a personal profile at this time. But, for the sake of getting rid of this issue, I will check out this profile thing as my next step, as suggested.
PS
W is for short wheel base while V is for long. My S450 is long wheel base.
I think, in the good old days, both short and long wheel base S-class were sold in roughly comparable proportion. But now long wheel base units are sold more. Eg, MBUSA website seems to indicate that all models sold in the US are long wheel base units only. I am just a little picky about this.
Just curious, anyone here has a short wheel base W223?

On the short versus long discussion I was a bit surprised when I was negotiating with my dealer when he said even the majority of his customers prefer the short wheel base model. Myself I don't understand it as the rear space on the short is very much the same as on an E-class. Must be drivers who don't care about the rear space and have a small garage, perhaps drive a lot in European old town areas and find the size a burden but still want to enjoy the S-class ride and features? Anyway, good that Mercedes offers the choice. We should accept that owners have different preferences and priorities just like we discussed about the RWD versus AWD models.

But there was one time (~a month ago) when a similar (or the same, I am not sure) 'alarm' (I put this in quote as the sound did sound like a casual warning or some kind of a reminder) went on from the moment I pressed the ignition button and the moment I drove off. During this time, I checked that the doors/boot were not ajar and everything seemed fine without any message in both driver display and central big display. So, I just took off and the sound stopped soon.
