I just came from the Toyota dealership and asked them to turn my seatbelt dings off. They told me it couldn't be done. I showed them the page in the owner's manual that instructed me to have the dealer disable the buzzer if I didn't like it.

To make a long story short...the tech was able to plug his scan tool into my 07 TCH and turn offf the passenger and driver's side buzzers!!

Excelent!!
