Door lock feature

[ORLFLA]

I'm a new member and I am curious about the door locking system on a 2002 Sienna XLE that we just purchased. I can't find in the owner's manual where it says the doors should all lock when you shift out of Park or when you reach a certain speed. Therefore I'm assuming this is not a feature that's available for this year. Does anyone know if that's correct?
Thanks

I believe the door locks can be adjusted to different settings by the dealer. For example, putting the car into drive locks doors or park unlocks doors. I also don't think they charge much if anything to change it.
