Tutorials:Legacy Seat Chime Disable
From SubiWiki
For those that find the repetitive reminder 'ding-ding-ding' absolutely maddening when sitting in the car without the seatbelt on, here is a fix for it. Note this does not remove the initial chime when you first turn on the ignition, but only the annoying repeating chime. Also keep in mind that this is not a permanent fix... any time the battery is disconnected, the annoying chime will be reset and will have to be disabled again.
Seat Belt Chime Disable:
1. Put key in the ignition and turn car to ACC (do not start the engine)
2. Buckle and unbuckle (completely) the drivers side belt, 20 times in under 30 seconds.
3. Turn off ignition, then back on; chime should be disabled.
