Hi guys, I think you'll find that the 4x4-i is just the fancy branding to tie in the added features of the new model (adding ESP, up hill start & descent control). The extra programming is added to the ABS/4WD module along with some new and revised sensors.
up hill start: on inclines >10% the ABS system holds the brakes an extra couple of seconds. also works when reversing [up an incline]
descent control: uses the ABS system to keep brake pressure to maintain speed of 8km/h (also works in reverse). Operates in LOCK mode only so as to use full traction and engine braking assist through the driveline.
ESP (program that provides vehicle stability and traction control): poor-man's LSD - you'll find out why when you're deep in the soft sand. ABS system brakes the slipping wheel...great for dirt and wet roads though
up hill start and down hill descent are handy for the lazy but from a safety standpoint, ESP is the bomb that should be standard on every single car worldwide!

Have had a little play with the ESP on our T31 and here is what I found ( which is pretty much what the manual says about it )
The second day we had the car we went for a drive up mount sugar loaf ( local 4wd area ) it wasn't long before I detoured of hard ground and found a narly rock ledge I was dying to try out just to see if boris was telling the truth in the add. The decent was easy despite this being a high rated difficulty hill the clearance was the only problem and all the electronics worked together to stop wheel spin and braking lock up ... easy!!!
When we had to go back up my disappointment arose half way up the car bogged down in power and stalled then I had to ride the clutch all the way to get up this is where I thought the capabilities of the X-trail were realised .. it needs low range.
Not happy, I had another attack plan so I went out 2 weeks later to try again ( Much to my mothers fright who was in the car and thought we were going for a nice sunday drive ) I went down 2 rock ledges this time and like before decent was easy !!
Going back up however I turned ESP off stuck it in first and we slowly climbed our way up the two hills aloteasier than before no stalling no clutch sliping, she went up just like a normal 4wd.
The reason I belive is that when the ESP notices wheel slip it takes power away from the engine to minimise but I had that much wheel spin it near killed the engine power so turning it off I was able to keep 100% down to all the wheels and claw my way up the rock ledge.
Now I am very impressed with he X-trail If this doesnt all make sense let me know and I will write it again ...Just what I have found any way
