new 2003 h2 owner have some operation questions

[queth]

I just bought a H2 2003 i'm guessing luxery model.
It doesn't have a manual of course so I have a couple questions until i buy one.
The 1 and 2 and the button on the top left driver door, i take it are for memorizing the positions of seats and things. How do you tell it to save the slot?

on the steering wheel, i know what the volume and seek do but not the others. Is there blue tooth hands free voice in this? I noiced the speak button.

when turning on defroster vent is there a way to keep climate control working to?

What are the different buttons with 4 and a lock for? I know something to do with gears but i don't know what. The same with the one at the top with the 4 wheels and x in the rear axl. I wonder if i'm driving in some gas guzzling mode.


Auxilary inputs for the cd/radio system exist anywhere? maybe RCA inputs?

why do the 12 volt chargers stay on when the car is off? Can i change that? I don't want a dead battery.
