To disable the seatbelt chime on a Honda Pilot, start the vehicle and ensure the driver's seatbelt is unbuckled. Turn the ignition to the "ON" position without starting the engine, then buckle and unbuckle the seatbelt three times within 10 seconds. After that, turn the ignition off. When you start the vehicle again, the seatbelt chime should be disabled.
