Hazard Flash with Lock/Unlock

I looked in the Service Manual, Door & Lock System PDF and on Page 49 there is a mention of the "hazard answer back" function for the remote door locking, along with the mention that there are 4 time delays available for the auto lock function and also different time delays when holding down the unlock button to make the windows roll down. That could certainly come in handy for those who inadvertently press the unlock key and have the windows come down unexpectedly.
I didn't see anywhere in the Service Manual where you could put the car in the programmable mode for those features. Does anyone know, or is this something that the dealer would have to do by plugging some computer device into the car ?
Thanks
