automatic door lock on 307

I recently had a 207 as replacement car. This car had automatic door locking
when you start driving.
The dealer told me that my 307 had this function too.
He said I just had to push the central door lock button for a few seconds.
This is also printed in the manual.
But it won't work on my car...
Is this function only implemented in more recent cars? Mine is a 2003 2
liter XS automatic.

He means the central locking button in the middle of the car ..press and hold
it for 3 secs .If this still fails the b.s.i needs to be configurated to
"automatic locking"

 

Thanks a lot, that's what I tried indeed.
So I will have to ask again in the garage... :-(
