I just bought a 2015 IS250. It has navigation, but when I went in to adjust the vehicle setting gs, per the manual, I don't have the option for "other vehicle settings". Also, how can I disable the seatbelt chime? Any insight from anyone?

You want to be in the 3d Gen IS forum. But I can't imagine there is a setting to disable the seatbelt chime--it's a safety feature. On my 2d Gen IS, there was a way to do it--if you Google it, you should find it. I can't remember what it was.

I used the Carista app to disable the seatbelt chime. My father never puts his on when in my GX460

our computers at Lexus can disable it just bring it in and ask!
