First off don't flame me for defeating a safety feature, the blinking lights on the dash serve that purpose just fine and less annoyingly. My 4th Gen did not have an audible warning (just the lights) and I lived through 120K miles of driving it.
I tried all of the recipes for disabling the audible seat belt chime on other threads without success. Finally, I called the dealer's service dept, the good news is they said that if the manual lists it as "customizable" they will do it, the bad news is that they wanted $52.80 to turn the key and punch a few buttons in the secret sequence. The service guy suggested that I talk to my salesman to get it done for free. The sales manager setup an appointment for tomorrow morning. We'll see how it goes and if I can learn anything about the process.
