i have the 2015 F sport. right under the "brake hold" button theres an "auto" light, how do you turn it on and what functions it serves? that little "auto" light left of the Parking button.

 

Its for the auto engagement of paking brakes when you shift into P and also auto release when you shift into R or D.

To activate while in P hold the brake switch up for 5 secs to enable the function. Pressing down for 5 secs while in P to disable the function. The corresponding green indicator on the auto light will be turn on or off.

 

Thanks a bunch, will try this.
