What is this audible signal?

[fxpose]

After a few minutes of driving I hear a ding ding ding signal in my 2006 X5. This happens every time. What is it telling me?

Thanks!

Fasten Seat Belt?

Thanks for the replies. Actually, nothing is ajar. This audible signal usually happens just once at about 10 minutes into the ride, every time.
Can it signal needing some mechanical attention?

The display in the instrument cluster usually shows what the warning chimes are for as the chime goes off. See if anything is shown on the cluster display next time it goes off.

could it happen to be coincidentally occurring at the top of the hour? if you have the memo feature on it beeps on the top of every hour

Could be the speed limit warning. You can set a speed limit on the computer and when you hit that limit it bings at you.

Thanks! I'm going to look into all these possibilities as this is a newly purchased CPO vehicle and the previous owner could have set something.

'Memo' function, it occurs about 10 seconds before the top of the hour. If you have nav the ●)))) symbol is at the bottom of the screen adjacent the time.
