Automatic Locking

[Bergers]

Hi

Just bought a 2008 Pathfinder Adventura.  I'm trying to work out a couple of things as there was no owners manual.

1 - Is there automatic door locking when the car reaches 15mph?  If so, does it make the central locking button light come on?  Can it be auto lock be activated if it has been turned off?

2 - When the car is being opened either with the key fob or keyless, is it possible to only have the drivers door unlock and then a second press unlocks the other doors?

Thanks everyone

Some of these functions should be programmable by the dealer 

The auto-locking is something that may be regional (country) and also a requirement from the insurance companies
Not sure about the one touch door locking though
