Before proceeding, it's noteworthy to mention that this article is NOT promoting not wearing your seat belt. It is a legal requirement in most states. This article merely shows you the procedure on how to stop the constant seat belt chime for whatever your reason may be. This modification is solely the owner/modifier's responsibility of liability. It is your own responsibility to protect yourself and other passengers while driving.
