What kind of adjustments? Adjust the driving habits to icy road conditions that's it.

Your truck is an awesome machine. That being said, slow down.
Technology is great, point the wheels where you want to go and use a steady pedal. VSC works great if you let it do its job.
I heard that the 2nd gear start button is for the snow, but I can't confirm. Maybe someone else will chime in on that.
Stay safe out there.
 
2nd button forces you to be easy on the gas. Starts you in second instead of first to rob you of that grip slipping 1st gear power. I'm sure VSC works fine. I just don't like my truck thinking it's smarter than me. I know how to drive in the snow. I don't want technologies messing with what I feel is normal snow driving. VSC just makes me think more about what my car is going to do. I'd rather it just let me drive.

We started loosing that option with the advent of ABS
 
Just drove through 4 feet of snow and falling snow at Crater lake. Put chains on rear but it was solid without the chains. Of course easy ongas and decent tires helped. My tires are just Kumho AT tires, nothing special.
 
thanks everyone, I am no stranger to four wheel drives,my 2010 tundra has a knob on dash to engage 4x4 I have only driven landcruiser about seven hundred miles since I bought. lc is my sixth 4x4 and I don't go out and get stuck in 4 wheel I engage to get out.get stuck in 4 wheel without a winch your in trouble.so what I was asking in the lc I assume it is running in 4 high full time but it has that damn lever on the console for 4 high and low instead of low only.i think but not sure the lc 4 wheel drivetrain is much more advanced so on ice or mud let the truck make the adjustments correct.
 
Read up on ATRAC, center diff lock, and VSC and how they interact with 4Lo. I'm typically in 4Lo off gravel for better gearing. Center lock is my bail out.

Regarding icy roads, as someone else posted, just don't drive like an asshat and you'll do as well as possible... But true ice is no match for any AT or MT tire so be careful; 6000lbs will go where it wants to.
 
The Center Diff system on the 100-Series is basically an open diff design. Whereas the 80-Series has a viscous coupler that is more of a bridge between the Center Diff being fully locked and unlocked. And I believe Toyota returned to the viscous coupler design on the 200-Series? Both systems seem to have their +'s and -'s...but why Toyota hasn't made a long term commitment and continues to vacillate between the center diff design is beyond me.

Consequently I tend to use my selectable center diff much more often than my 80-Series wheel'n buddies...
 
I agree that I don't want my vehicle to make decisions for me, but I would leave the diff open on ice. You will force wheel slippage while turning with it locked. The lock is so you don't get stuck- like in deep snow, mud, uneven terrain, etc. On an icy road just leave it in hi, diff open, and drive. Ideally you could turn off VSC at will, but you can't. Yet...

To directly answer your question, yes your truck is full time 4WD High. You can shift into 4LO using the aforementioned lever.

No changes need to be made when driving on snow or ice except your driving style as previously mentioned.

The 200 and some of the 120's use a Torsen center differential that is supposedly much better than the Viscous and open center differentials. Torsen as in torque sensing that activates immediately, before slippage occurs... and without losing power/generating extra heat, as the viscous does.
