The only "tricks" that *might* temporarily silence the chime are often unreliable and vary depending on the specific truck model and trim level:
* Buckling the seatbelt: The most reliable way to stop the chime is to simply buckle your seatbelt.
* Improvised Solutions (Generally unreliable and not recommended): Some people try wedging something in the buckle to fool the sensor, but this is dangerous and can lead to malfunction of the system. It's also unlikely to work reliably.
Instead of trying to disable the chime, consider:
* Addressing the reason you're avoiding the seatbelt: If you find the seatbelt uncomfortable, try adjusting it properly. If it's restricting movement, you may need a different seatbelt extender (make sure it's a properly certified one for safety).
* Tolerating the chime: The chime is a brief annoyance compared to the potential consequences of not wearing a seatbelt in an accident.
In short: Don't try to disable the seatbelt chime. It's there for your safety.
