Seat Arona locking/uncloking unavailable in settings

[ADAMHD35]

I have had my Aona a little over a month and I know there is a fature to enable or disable the auto locking feature when you begin to drive but I am unable to acess it in the settings menu. It tells me to turn ignition on and when i do it says 'this function is currently not available' I am locked out of the particular setting option for some reason. Any ehlp would be much appreciated.
