The Porsche website states that one of the passive safety features for my 2015 911 GTS is the alarm system that can be deactivated using the button on the lower B-pillar on the driver side. I have no such button on my car. And that is not what my owner's manual states how to deactivate the system. When I asked my dealership service people, they started looking for a button, but could find it either. They didn't know why it wasn't there as stated.
I tried to send Porsche a question about this issue using their same website, and the messaged failed in their system, kicking back a message to me: "ERROR".
But here is the ironic part, Porsche is so proud of their website, that after I visited their site, they wanted me to respond to a survey about their site and what I thought of it. I couldn't give it very high marks.

 

don't remember ever reading such a thing in the manual regarding a button on the B pillar to deactivate alarm - manual does say that to deactivate, press fob lock button twice within 2 seconds
