In the end the button was in fact on the dash that I had to use not on the single hand lever as described on page 74 (if I remember the page number correctly).
So bottom line is ... don't believe all you read in those manuals
In this case, the manual tells you what the function does. I'm not debating on the reliability or the ability of it. A lot of it is up to the DRIVER to be able to figure it out and respond. If the driver can't, then no technology will help you.
