I'm sure you're going to get bombarded with everyone telling you just to buckle up and it's happened many times. Hopefully it won't get out of hand as it has in the past.
What I do find interesting is that Chrysler would even put that info. in their Owner's Manual!! But, to each his/her own reasons for doing so. It just would not be a choice for me.
I agree that the chiming can get annoying and for some reason, I believe it stops chiming after a certain amount of time when not buckled up.
