Nevermind. My bad. In the quick guide it says "such as" locking/unlocking, but in the main manual it is more clear that it is in fact linked to the lock/unlock. Just checked and it does work with the lock/unlock.
I guess I was tired when I was reading things over after all the excitement at the dealer :-).
I'm still curious, though, if they can be linked to other actions, other than lock/unlock, i.e. moving to Park, Drive.
