In case anyone wants to disable the chime, this worked on my 2015. I came here first (I love these forums) but didn't find anything so here's the link: https://www.youtube.com/watch?v=FyGrFRC0QX0 I drive for Uber and even though I really want my passengers to wear their seat belts, it's not worth it for me to argue with them and cancel the ride over it. So I disabled the passenger side only. I don't mind the reminder for me in the driver's seat, I always wear mine. As the video points out, it's also useful if you have a dog that triggers the warning. Step by step: 0 -- (Video says to engage the e-brake. I don't know if that's necessary but I did engage my parking brake just in case.) 1 -- Wait for the seat belt light indicator to go out after 1 minute 2 -- Fasten and unfasten the seat belt (driver or passenger depending on which you want) 3 times. 3 -- The light will come back on 4 -- Fasten and unfasten once 5 -- The light will flash. 6 -- When it stops flashing, you're done! [Repeat the process to re-engage the chime*] * Honestly chime is not the word, it's really more of an alarm. It gets obnoxious on the 3rd alert.
