Can I make mine like this?

[JochenWoern]

In my limited research on this, it seems to be a one year only (2004) deal. From what I've read, it's basically auto 4wd with no option for 2 hi.

So would Auto 4wd not pretty much be the same as AWD? An AWD does not have all 4 wheels powered at all times, the wheel needing the traction is where the computer will move the power towards.

Is that not very similar if not identical on Auto 4wd?

That looks more like an Auto 4x4 symbol with the top one being 2wd.

The top button is to shut off/disable the stability system, it is NOT a 2wd button.

Auto 4wd and all wheel drive are VERY different. There's a thread here that explains it well. I'll have to track it down for you

Please do, thanks Jacob.

And then I would still like to know what really do I have here? Will my set up be sufficient in the snow on pavement, or will I get into trouble once heading to the Sierra Nevadas in a snow storm?

You'll be fine in snow

So after reading this it would appear that the Auto 4wd is an on demand AWD system, so it is very similar if not identical to what I mentioned earlier.

No?

Similar, but different. The way I understand it, AWD sends power to front and rear constantly and auto 4wd sends power to the rear until there is slippage, then sends power to the front as needed. I could be way off though.

All wheel drive has power going to all four wheels 100% of the time.

Auto 4x4 only engages 4x4 when it senses the conditions where 4wd may be needed. When not needed only one wheel has power going to it. In a limited slip diff/posi trac situation both rear wheels could get power when one starts to spin. When 4wd is engaged then the one wheel in back and one wheel in front has power going to it until a wheel start to spin then the other wheel is engaged and recieves power to it.

So, no. Completely different. If you crawl under yours you'll see a transfer case at the front of your vehicle for your front axles. All wheel drive does not have a transfer case

Got it, thanks very much again.

07 Denali, ......... I like to hear more, ......

Sold my 03 duramax for it. 130k miles, one owner, loaded, 6.2 awd. I was the first one to drive it haha she's black. Coupe little things that are missing or not working so they are all cosmetic. But I stole this thing! I got it for about $7k less than blue book. It is SO CLEAN! I'm excited to get into something that rides a little smoother than a brick. Lol

Both a 4x4 and AWD vehicle have transfer cases and front differentials. they operate similar but not the same. the AWD does have torque going to both axles all the type (also called full time AWD). 4x4 vehicles operate in 2wd mode, and auto 4wd which is torque to the rear axle until slip is reached and then the front axle is engaged/disengaged upon speed sensor slip readings. (this may also be called part time - AWD depending on your area's terminology). the transfer cases simply divide torque from the transmission to send either fore or aft.
