That being said, not sure why you wouldn't want to drive the Borrego in the snow? With proper tires it shouldn't be an issue.
The AWD system of the borrego leaves much to be desired... Even when the dial is set to 4x4, it needs to detect slippage before the front does anything useful. I question why even have the dial, other than low range. There is zero difference between auto and 4x4. The traction control constantly fights the AWD also. From a dead stop, I've gotten the borrego stuck in 4 inches of snow on a slight incline, I ended up having to back up and turn around. Turning off traction control helps significantly in slow speed snow/ice conditions.
One of the offroad magazines did a review of the borrego, and the summary was pretty much it can't get out of its own way.
(I've got the borrego version with the torson Torque-on-demand center transfer case, I understand there is a version with an actual locking diff that would be far more capable, if you can live with the limitations of a real transfer case.)
My other two vehicles also have nokians on them, the borrego is on its OEM all seasons, so that by itself makes it an invalid test. The other two vehicles are a subaru wrx with nokian wrg2's, you simply can't get any better on snow/ice than the subaru, and a first gen sportage with locking Warn hubs on nokian vaativa's. Yank the 4x4 lever on that, and the front has no choice but to help out! Putting nokians on the borrego would help, but it doesn't get over the limitations of the AWD.
