My adrenalin is AWD if I scroll through the odometer settings for oil life etc. it has 4wd and 4wdlo as options. It states that you should not drive in 4wd unless in heavy snow or mud. I can lock mine into 4wd. Linited02 I do not have those three buttons on the right for 4wd instead two are dummy plates and the other is for heated mirrors and windshield. The three buttons to the left I have and that is how I enter into the computer to change from AWD to 4wd.
Some info I "borrowed" from this link:
http://www.zercustoms.com/news/2008-Ford-Sport-Trac-Adrenalin.html
Along with the standard 4x2 drivetrain, Sport Trac Adrenalin offers an all-wheel-drive system that’s more suitable for a street cruiser. In addition to providing sure-footedness on slick surfaces, Adrenalin’s AWD system offers a performance advantage as well. The system seamlessly transfers torque from the rear wheels to the front wheels as required to provide confident handling, reducing wheel spin and improving cornering.
Does not sound like a true AWD system to me, climb under your truck and look at the side of the transfercase. Do you see a shift motor? If you do, then Ford is misrepresenting an "Auto 4wd" system for an AWD system. AWD, by definition, can not have 4lo nor 4hi.
I went digging for what I am trying to say, but in better terminology. I found a thread on here that quotes an article written by Eric Peters.

All-wheel-drive (AWD)
This is a system in which engine power can be sent to all four wheels (or to individual wheels/pairs of wheels) as necessary to maintain traction. As recently as five or six years ago, only a few makes/models offered AWD systems; today, AWD is either standard or available optionally on many types of passenger cars, wagons, minivans and light-duty, car-based "crossovers."
The upside: AWD provides excellent all-year/all-weather grip -- on snow-covered roads in winter and on dry (or wet) paved roads in summer. And unlike a truck-style 4x4 system, AWD is optimized as much for use on smooth, paved surfaces as it is for use in snow (or unpaved gravel and dirt). High-performance AWD-equipped sports cars and sedans offer incredible dry-weather, on-road handling with superior wintry weather capability. Also, AWD systems do not require any driver involvement; power is automatically routed to the wheels with the most traction -- typically via a device known as a viscous coupling. Modern systems are highly efficient and there is usually very little fuel economy penalty vs. a FWD (or rear-wheel-drive) vehicle.
The downside: Like FWD, AWD is not designed for severe off-road use;
there is no two-speed transfer case or 4x4 Low-range gearing. AWD can also add substantially to the purchase price of the vehicle -- sometimes by as much as several thousand dollars.
The lowdown: AWD is an excellent choice for the enthusiast-oriented driver who values dry-weather handling and lateral grip in a high-speed corner as much as being able to get out of his driveway when it snows.
Hope this helps clear up the confusion.
: I did some research that I should have done to begin with about the Adrenalin. I found some sites say that it has AWD and some say 4x4. I found an interior picture that show's the 4x4 auto, high and low meaning it can't be AWD. Unless of course Ford offered it both ways which I was sure they didn't.(AWD only) Here is the picture I found-
