This works on older models. Should work on your 2013 as well. If not the dealer can disable it( don't let them tell you they can't - right in Owner's Manual, page 60, that they can ).
The following steps must occur within the first 60 seconds of the ignition switch being turned to the ON/RUN position( don't start the vehicle ).
It can be reactivated by repeating this procedure. This only stoips the annoying chime. The seatbelt light wiill still show/blink.
- With all doors closed, and the ignition switch in the LOCK position, buckle the driver or front passenger seat belt.
- Turn the ignition switch to the ON/RUN position and wait for the Seat Belt Reminder Light to turn off.
Within 60 seconds of turning the ignition switch to the ON/RUN position, unbuckle and then re-buckle the driver or front passenger seat belt at least three times within 10 seconds, ending with the seat belt buckled.
- Turn the ignition switch to the LOCK position. A single chime will sound to signify that you have successfully completed the programming.
