Not a problem, more of a curiosity. When I cold start my 2020 E450, I see a message "Please Wait..." in the middle of the instrument panel. After a half-minute or so it goes away. If I start the car when it's warmed up, the message shows for a quick second and goes away. Does anyone know specifically what on the car is being monitored to cause this message?

 

It could be anyone of a dozen different systems.

 

I have a 2020 E450 wagon and never seen that message. No idea what it could be.

 

Which display option is normally shown where "Please Wait" is shown?

My 2019 E450 wagon can show several different ones, and perhaps that option can't display the info for a few seconds. I know if I have my main display on Navi, it takes a bit for the maps to load.

I seem to recall seeing something like that in my heads-up display. I feel like it has something to do with the audio system loading up (in my case, starting up the car and the car loads up from where it left off on my media card).

 

What do you have set on the middle between the gauges normally? If its the map, that could be the cause as its gathering nav data.

 

I get please wait when I have it on the radio screen. Its just waiting fo the infotainment to load

 

I can understand a "moment" to load or reload data, but why would it take longer (significantly longer according to OP's count) on a cold start?

 

yep definitely would help to find out what screen OP is on. without that we are just guessing. I know if takes a bit for me to use my telephone once i jump in the car. whether cold or not haven't noticed the difference?

 

OP here. Yes, it was the Sirius/XM satellite radio connection that was causing the Wait message.

I usually have the Radio app showing in my main instrument panel (where the Please Wait message appeared). I'm so used to it being there that I just blanked it out of my mind when describing my original symptoms. In further testing, I think the delay in the Wait message is because my car is garaged and there is a short time for the Sirius/XM satellite signal to connect. Depending on satellite locations, the time to connect can vary. I've had satellite radio in my cars for over 15 years and I'm so used to there being a delay in signal acquisition, that I didn't even put one and one to together, and connect it with the Wait message. Once outside, I'll have a clear signal and radio connection is almost automatic.

(The cold start comment of mine was sort of a red herring. The car is cold in the morning when I start it. However, the garage and structure around it partially weaken the received signal strength, which is the important factor. Once outside, my car is warmed up, so if I should restart it outside, with no obstructions satellite acquisition is almost instantaneous.)
