It's about European Murano but there is text how ALL_MODE 4x4 in our Murano works, there is also information about changes in euro MO in comparison to US MO.
So how it works:
"The system has two modes – Auto and Lock – selected via a switch on the dashboard. As the name implies, Auto is a ‘set-and-forget’ mode and for much of the time the system operates in front-wheel drive for optimum fuel efficiency. Engine torque is transferred to the CVT transmission and to the front transfer case, and the transfer case in turn is in constant mesh with, and driving, the propeller shaft (but not the rear wheels) at all times. Sensors linking the engine’s ECU and the anti-lock brakes, meanwhile, constantly monitor and anticipate wheel slippage.
Located just ahead of the rear final drive is an electronically-controlled coupling (Fig.2) which enables drive to be fed through both front and rear axles. Its main clutch is connected to the propeller shaft, while a control clutch connects to the rear drive
The control clutch features a cam system comprising two plates with asymmetric grooves on both faces, separated by a series of ball bearings. In order to activate rear-wheel drive, the control clutch is engaged by an electromagnet and this causes one of the plates to be slowed down, causing the ball bearings to move to one end of the grooves. This forces the plates to separate which in turn applies pressure to the main clutch, and torque is transmitted between the two to give rear-wheel drive (Figs. 3 and 4). The main clutch transmits torque relative to the current applied to the electromagnet and the resulting engagement pressure.
The instant ALL MODE anticipates wheel slippage when encountering unexpected slippery conditions on-road, such as mud, wet leaves or ice, the coupling is automatically activated and drive is correctly apportioned, the maximum torque split being 53/47 front-to-rear. A torque-limiter prevents excessive torque being sent to the rear wheels.
If conditions become trickier, or the Murano is being used off-road, the system can be switched to Lock, which permanently locks the chassis into four-wheel drive mode. In this condition, the control unit supplies the maximum amount of current to the electromagnet (Fig.5). This causes the control clutch cam plates to apply maximum pressure to the main clutch to give a 53/47 split in transmitted drive, and this is available up to a speed of approximately 18 mph (US and Canadian MO after 2005 to 6 mph). Over this speed, the system reverts to Auto operation, switching back to Lock when the Murano is slowed.
ALL MODE offers further sophistication during everyday driving (Fig. 6). Under light acceleration the electromagnetic clutch is engaged by up to 50%, dividing the torque to suit the conditions. During hard acceleration, the unit is fully engaged (100%) to allow the maximum permissible front/rear torque split of 53/47.
And when the Murano is being driven at fairly constant speeds, a small drag current is supplied to the electromagnet to ensure that the system is ready to act instantaneously.
Finally, when the ABS is operated, the coupling is de-energised so that the front and rear axles can be controlled individually.
As a four-wheel drive vehicle, Murano has a strong active safety story, starting with the elevated driving position which provides a better vantage point allowing the driver to be more aware of his or her surroundings.
The ALL MODE electronic four-wheel drive system not only provides drive to all four wheels, but sensors constantly monitor available grip to ensure safe progress at all times. A standard feature on Murano is the electronic stability programme, ESP+, which either brakes individual wheels or redistributes engine torque to regain stability if traction is lost, as well as reducing the unwanted effects of excess understeer or oversteer. (In US and Canadian MO it's option of Dynamic Control Package and it's called VDC)"
I think that also US MO has 53:47 torque split (not like in manual 50:50) and there is always small amount of torque on rear wheels for faster reaction like in euro MO. They didn't mention about any change in AWD in European MO but they mention that they've changed CVT computer program. I think it equals that they hadn't change it (AWD). Only one difference in European AWD is that Lock MODE is still to 18mph but AWD switch operates like in 2005> US MO. (I have driven European MO at my Poland service/dealer)

One quick question though:
Is it OK to drive the vehicle over 18 MPH in the lock mode?
e.g. I am driving up to Tahoe in the snow on I80 and it starts to get slippery, I slow to 25 MPH, not stopping and then flip the switch from AUTO AWD to LOCK and then continue to vary my speeds from say 25 -45 MPH. Will this screw up the tranny? i.e. do I need to keep it below 18 MPH?
Also, what if one forget it's in lock, the snow clears up and I you’re doing 75 MPH all of a sudden again?
Perhaps this is a stupid question to some, but after owning an ‘82 Toyota truck; there were definitely no no's with regard to going too fast when using 4 wheel drive, even when in the 4 wheel high gear.
Cheers!

Nope, it won't damage your drivetrain. Above 18mph, it switches back to AUTO mode, even though the light on the dash still says AWD LOCK. Once your speed drops below 18mph, it actually locks the AWD 50/50 F/R. That said, its probably not a great idea to use AWD Lock unless its REALLY slippery out there, since you'll wear out the AWD unnecessarily. |

Great, appreciate the reassurance. I'm never one to assume too much. Especially after paying $35K for my new AWD SL.
BTW: Just bought the ’07 AWD SL Black on Latte w/the touring package, including: NAV, XM, Dynamic Stability Control, Traction Control and the tire pressure monitor. Thus far I must say, of all the things I like about the vehicle, the back up camera is so damn cool. Especially at night. MPG kind of sucks @ 17.5, but then, I don’t exactly drive it like a Honda or Lexus driver would.

I guess I assumed he had a 2003-4 since he mentioned 18mph. I admit I like the fact that my MO has AWD lock up to 18mph, rather than 6mph, and am keeping my fingers crossed the AWD system holds up under my normal usage. |
|
|
| teonek |
| I've also read somewhere (when I search info about MO AWD) that on 2005>2007 50/50 is to 6 mph and it is slowly engaging/disengaging from/to 18 mph. I think that the biggest difference between 2003-04 and 05-07 AWD control unit could be their softer engaging not only in LOCK but also in AUTO. |

| hfelknor |
There is a lot of info out there.
Much of it wrong.
Here's one
"2007 Nissan Murano: Highlights
This midsize car-type SUV seats five and is based on a car-type design. Models are S, SL, and SE. All use a 245-hp V6 and a continuously variable automatic transmission (CVT). The SE's has a manual-shift mode that mimics preset gears. S and SL offer front-wheel drive or all-wheel drive. SE is AWD only. Murano's AWD system lacks low-range gearing, but a console button can lock in a 50/50 power split for extra traction up to 30 mph. ABS is standard. So are front side airbags and curtain side airbags with rollover deployment. SEs come with a firmer suspension and xenon headlamps. An antiskid system is available, as is a navigation system and DVD entertainment. SL and SE include a rearview camera."
Who said that?
http://auto.consumerguide.com/auto/...x.cfm/id/39112/
30 sounds better than 18......and certainly sounds better than 6! :D
But a little company called Nissan says this:
"All-Wheel Drive
It might be raining, icy, even snowing, but you're prepared. The All-Wheel Drive (AWD) model, with its superior traction and handling, can help negotiate even the most challenging conditions. And because it's automatic, Murano switches seamlessly between AWD and front-wheel drive, giving you either the optimal control of AWD or the optimal fuel economy* of front-wheel drive. What's more, you can lock in AWD, a definite advantage at lower speeds**, by simply pressing the AWD lock button.
Compare Xterra, Murano, Pathfinder, and Armada drivetrains.
**Driver can lock-in AWD at speeds up to 6 miles per hour."
Of course, what do they know? ;)

Gonzo-
The MO's rear-wheel engagement is not simply ON or OFF, it is variable, from 0 to 100%. In normal driving the ABS sensors on each wheel will monitor wheel rotation and engage the AWD clutch pack if front wheelspin is detected.
Once the rear wheels are engaged the AWD system will begin to gradually reduce the clutch pack engagement pressure, sending less torque to the rear. However if wheel slippage is again detected the clutch pack will adjust (increase) the engagement pressure to minimize wheelspin. This process will go on until RWD is no longer required. My guess is that this all occurs in matter of a few seconds.

I ask because as I mention before.... what happens if you are on dry pavement and take a hard turn (not that I do), there is some wheel slippage. Knowing how week the system is I get concerned, so coming out of the turn I take my foot off the gas (not what I really want to do) just to stop "any slippage" on the dry pavement.
What do you think? I guess I should simply slow down on this one turn I hit almost every day. |

If it is dry pavement, any wheel slippage when cornering is probably because you are going too fast already, not because the tires cannot grip to accelerate the car. In that case, it would be unrelated to the AWD system. |
|

| njjoe |
Gonzo-
If you are taking a sharp turn under power and the inside front tire loses traction and spins then the AWD system will engage the rear wheels to compensate for the lost traction. Once traction is regained the clutch pack will disengage the rear wheels.
The MO does not have a differential between the front and rear drive shafts, and therefore cannot compensate for the different shaft speeds when making a turn, especially a sharp turn. My guess is that this type of activity would be hard on the fragile transfer case.
If it was a rental or lease I would not alter my driving habits. However, if you plan on keeping the Gonzomobile after the powertrain warranty has expired then I would lighten up on that particular turn.

I like your idea about the AWD activation light. It would be interesting to know when the rear wheels are called into play.
-njjoe |

| Eric L. |
Keep in mind that the AWD system is only active when you are accelerating, since I would doubt any AWD engagement with your foot off the throttle would push any meaningful torque to a non slipping wheel (well not enough to make a difference anyways). AWD is mainly to help you get going in a straight line, not cornering.
I suppose if you are a racer and accelerate through a turn, then AWD would matter, but we don't exactly have Quattro on the MO.
You'd have to be really cooking it to spin the inside front wheel on a turn! :D Not even sure that would be possible with the torque challenged CVT. |
|
|
| Gonzo |
| Oh I don't know... its pretty easy to spin the front wheels on wet pavement while turning in any FWD drive car I've had with less than 100 HP.... do you think the MO is that pathetic? |

Probably because I have AWD and VDC, but even with VDC off, I have never been able to spin the front wheels, except maybe on ice. The CVT really bogs it down when you nail the gas from a standstill. But then the MO is a crossover, not a sports car, so I don't care if it can spin its wheels. |

Says who? AWD is to help you get additional traction when the primary drive wheels have insufficient traction, regardless of what direction you are traveling in.
There is this intersection where the secondary road is a steep incline with a stop sign at the top of the hill. When the road is even slightly damp it is not uncommon for FWD cars to spin the inside tire when accelerating onto the primary road. This happened to me several times when I had the rental FWD MO. However, my AWD MO handles the same intersection with only a slight initial chirp from the front inside tire. In this particular case the rear wheels are helping push the MO through the turn.
The MO does not have a center differential so the AWD system can not compensate for the different driveshaft speeds when the car is cornering. However, when traction is limited the wheel slippage will prevent the driveline from binding up when cornering.

I'm too chicken to try but I would spin the front tires on my 1989 Pulsar easily.... of course the car was lighter but that only had something like 90 HP. I'm sure you can get the MO to spin..... rev in neutral and drop into D.... purchase new CVT "there that was easy" :p |

I think what Eric meant is exactly what you also indicated in your post. AWD in MO does not transfer power side to side so if you are stuck in a corner where different power is needed for each wheel, the AWD on the MO will not be able to do its job like a true AWD can. However, when you are going straight, it does it fine... |

Pull up to the stop point. Turn wheel hard right. Nail it. If you don't get a "chirp" your MO needs a tuneup. :)

AWD with VDC MO's - you won't get any wheelspin on dry pavement.
As for better traction/handling with a FWD biased AWD such as that found on the MO - AWD only comes into play for HANDLING if you are applying throttle through a turn where FWD would otherwise understeer. Now I don't know too many STREET situations where you can even do that. You'd have to pretty much be flooring it through a corner (now I don't know ANYONE who does that on public streets, even with a sports car) and for your average AWD street car, the tires would lose grip and plow you into the opposite lane before AWD quells the understeer (I'm not even sure a full 50/50 split can do that).
Now if we were talking about the RWD biased AWD such as on the G35x or FX, thats a different story! :D |

| I just purchased a new Murano in December with AWD and VDC and within the first week of owning it, i had the scary experience of the front wheels skidding out on me. Yeah, i didn't know the road and the turn was tight and i was probably going a little too fast around that uphill turn but i thought that both the AWD and VDC failed me.. |
|
|
| Eric L. |
| AWD will not help you in a turn unless throttle oversteer is what you want. The VDC in the MO kicks in pretty late - I find that when driving in the snow I always correct the slide before VDC even engages. |
|
|
| RayH |
The electronic clutch which engages drive to the rear tires acts as the center differential. Since the amount of lockup is variable in auto mode, this allows for differing amounts of rotation between the front and rear.
I think there's maybe a bit of confusion about torque splits in AWD lock mode. If the system is truly locking then torque split no longer has any meaning; it's dynamic depending on the resistance felt at the tires. Full locking means torque split can go from 0/100 to 100/0. |
|
|
| Tyler_Canada |
| It's not full locking. It uses a clutch, which can (theoretically) slip regardless of the amount of pressure applied. |
|
|
| njjoe |
TC-
Ray is correct.
In normal operation the AWD clutch pack (just ahead of the rear differential) varies it's engagement from 0 to 100%, which equates to a torque split of 0 to 50% between the front and rear wheels.
When the AWD Lock is engaged the clutch pack is solidly locked and the split is maintained at 50%.
A well-designed multi-plate clutch will not slip when fully engaged. Just look at a motorcycle set-up.

The AWD is active when a front wheel loses traction and this could happen when you hit a patch of ice for example and not accelerating. |

| I have noticed that when rolling around 5 mph it is very easy to induce wheel spin even in my '05 SE w/ awd & vdc. Usually I get much better acceleration when already slightly moving and scared my cousin greatly setting the MO into a slight drift on a dry road pulling onto a perpendicular road with full acceleration. The point everyone needs to realize is that tires create grip, and with the proper amount of inertia any car can be put into a slide or spin wheels. That being said I hate leaving from a stand still, but I can beat most in my range from a roll with the manual shift. |

camkay-
I think your workshop engineer may be misinformed. Check your Owners Manual. Unless they beefed up the AWD system (transfer case) on the 2008 Gulf-spec MOs the AWD system will disengage at a much lower speed (assuming no wheel slippage is detected). In the US the AWD system will change from LOCK mode to AUTO mode at 6 mph.
The 2008 Gulf-spec MO appears to be identical to the 2007 US-spec MO SE. The Nissan website for Dubai lists the MO at 266 hp. How do you account for the additional 9 horsepower? Have you modified the engine?

Even IF you could keep the AWD locked up to 40mph, it would be detrimental to the drivetrain to do so. Coupled with the fact that there are very few, if any, instances at these speeds where locking the AWD would provide a benefit over having the 'auto' AWD active, it does not make sense for the 'lock' setting to be active at these speeds.
Out of curiosity, do you do any off-road driving in your MO? Do you go in the sand (is it soft sand), and how does it handle this type of terrain? |

This is a very thorough description - thanks for the information. I have a question though, when the AWD in engaged- either automatically or via the Lock switch - is the drive delivered to all 4 wheels or is it 1 wheel per axle ? By that I mean, do all 4 wheels receive torque reagrdless of whether the other wheel on the same axle has lost traction ?
Thanks,
John |

The MO does not have a mechanical limited slip on any axle, so there will be a bias towards the wheel with less traction on each axle, until the traction control and VDC kick in, which theoretically should brake the spinning wheel and redirect torque to the opposite wheel on that axle. But its not as good as a mechanical system. |

Thanks for the reply. I have an '07 SL MO without the VDC so I expect Iwill be more of the 1 wheel per axle than 2. Regardless I expect the second wheel drviing plus the greater road clearance over a sedan should get me through more snow (than a fwd Altima).

Well you'd have to be on an odd surface to get one wheel from each axle "stuck." One example could be if you drove two wheels on side side into a snow drift, with the other two still on the road. The ones deep into the drift will spin but the other two won't, although I think the front axle has traction control standard (uses the ABS) so you might get some grip from the other front wheel. |

If you're referring to what Nissan bills as ABLS (Active Braking Limited Slip) I believe that is NOT standard. At least not on my 04, it might be now. When I bought my 04 you had to have the VDC package to get the ABLS.
My MO has zero in the way of "traction control" other than the fact that it's a dynamic AWD vehicle. |

To answer your question... The AWD system will send up to 50% of the available torque to the rear wheels at any speed.

Thanks for the info & thanks for the welcome. The MO is actually my wife's & we love it. It is the only Vehicle we could agree on to buy. I'm a car guy so I like everything, we actually came across it by fluke. We were looking for a JEEP Liberty, found one and test drove it. Not a very nice or well built vehicle. We happened to see a MO, got to looking and fell in love. Now we own one. |
