4x4i auto-vs-2wd

Hi -
Referencing this thread I started yesterday, I am curious to know what you normally have selected via the 4x4i knob in the center console.

I manually switch to auto during inclement weather, otherwise I leave the knob on 2WD.

Full time AWD. You can always anticipate when you need it. Plus, from what I read, the AWD mode will be in 2WD until the computer detects slippage.

You can't always anticipate when you need it.

Notice on our auto-4wd. Whenever we move from a stop sign or Red light. The rear wheels get 5-15% power to move the vehicle. It goes into 2-front wheels drive when it's on the move, but then give 20% to the rear wheel if we're climbing steep slopes or hills. We've been getting 23-26mpg on i-auto.

Just the opposite. That's why it's called AUTO. It will be in 2WD until it detects slippage. The 2WD setting will always remain 2WD.

Yeah, that is what I meant. Auto = AWD.

NO! In AUTO mode, AWD kicks in only in slippery conditions. Otherwise, in normal driving conditions, AUTO = 2WD.

I think we are tracking on the same page, just semantics. To me, here is how I see it:

Lock = 4WD (4 wheels always moving)
Auto = AWD (2WD unless slippage is detected and the 4WD engaged)
2WD = Always 2WD

So, my definition of AWD is limited slip differential to allow & disallow rotational difference between front and rear axles (toggle between 2WD & 4WD).

Yeah, I think we're both on the same page, just expressing ourselves differently.

There is a difference between the Pathfinder's AWD system (that they call 4WD) and a true 4x4 system that is either full-time or selectable. In the Pathfinder, selecting 4WD Lock will provide equal power to both front and back axles for a limited amount of time, then it automatically switches back to AUTO after certain conditions are met (e.g., reaching a certain speed, turning the ignition off, etc.).

In AUTO, 4WD will engage, but it is my understanding that power will be transferred to the wheel(s) that are slipping, and not necessarily to one or the other axle. If someone who knows this for sure, please chime in and enlighten me.

If you watch the Driver Assist display in the center of the drivers pod (between the speedometer and the Tach) - and you are in AUTO, as you pull away from a dead stop, you can see the Pathfinder push 5% or so of the power to the rear wheels for just a moment while in that initial acceleration phase off the line. The rear wheels are not slipping, but I believe that the Pathfinder is putting some power to the rear wheels to encourage a smooth application of the engine power to the road.

I came here to post exactly this and that I use mostly "Auto" mode.

I leave mine on Auto also, but I wish Nissan uses RWD for the 2WD rather than FWD :D

Especially in the rain, let the i4x4 do their work...

I leave it in 2WD unless it's wet. Lock for real 4WD conditions (muddy roads, tracks etc).

Wonder if there's a difference in fuel economy.

I have always used 2WD selected. In the Pathy and my 2001 Suburban. I didn't see it in the Pathy owners manual but in my Suburban the owners manual specifically states to leave it in 2WD for normal driving. selecting Auto will decrease MPG slightly and decrease ride comfort. even though the manual says it will only add the additional traction when the computer sees it needs it. I know..... big difference between 2001 suburban and 2015 Pathy. but old learned habits are hard to break.


And I trust the older owners manual over the newer cars to give me true info. seems the newest owners manuals are written by lawyers and don't give us very much real info. like fuse and relay panel diagrams....newer cars just tell us to bring to dealer.
