Can't figure out how to turn this feature on my new CX-9 Signature. The CX-5 Grand Touring (that I traded in) had this feature from the factory, but the CX-9 doesn't. Pretty sure there is a way to enable it, but I can't find how to do it in any of the manuals. (I'm referring to the feature that automatically locks the doors after parking and walking away from the vehicle.

 

Finally realized that it was a simple matter of going to "Settings" on the so called Mazda Connect screen, then selecting "vehicle" then "Doors"

 

Center console go to vehicle settings and under Doors & lock you will see that option "auto lock" check that box
