2007~2015 Auto door lock function for CX9 2013

Hi Everyone, i've read in the catalogue of 2013 model for instruction of auto door lock when driving 20km/h and above, or shift from P to D to lock and unlock all doors. However my cx9 may doesnt have this function, how can i know that this available or not? Thanks.

Thanks @jal142, i've followed this instruction however unable to active the beep noise when holding lock button. Let me try again for longer hold the lock button.

Note sure if certain models of BCM carries this autolock feature. The Middle East model does not have the autolock function as well.
