Yep. 4x4 mode defaults back to auto 4x4. Regardless of what mode, the rear coupler disengages at speeds ~20mph and up.
Not at all unless maybe trying to do a very low speed parking lot maneuver with 4x4 lock on. You might feel some steering bind.can you notice when you're in 2WD vs 4x4? As soon as I put it in 4x4 I can feel a difference, almost like it's heavier.
I can feel it when going straight on a dry day. It's annoying... almost like I dropped an anchor... I let off the gas and it pulls back a bit.Not at all unless maybe trying to do a very low speed parking lot maneuver with 4x4 lock on. You might feel some steering bind.
The system is pretty keen on preserving itself and not staying engaged when it doesn't need to.
I'm almost sure all these mode changes do is adjust the electronic throttle response as well as the range and speed of gear changes of the new 9spd AT.I just gave "snow mode" a try today with a fresh couple of inches of snow outside. Needless to say, I do not like it... They made acceleration much slower to avoid wheel-spin but now when I press the gas I dont know if I dont have traction or the computer is holding me back.
