Based on this seemingly definitive explanation, there is a simple rule that should be followed:

If it is snowing or even heavy rain, put on the snow mode. If not, leave it off.

It has been programmed in a very sophisticated manner to NOT cause problems leaving it on for extended periods of time (like the entire winter if you live in a heavy winter area).

One point that was NOT definitive or clear in GT-R's explanation/quote was whether the Snow Mode throttle reduced sensitivity remains on past 12 mph or if it turns off with the 50:50 F:R torque split?

I would suggest that if the roads are snow-covered or even very wet, the reduced sensitivity would be an advantage at higher speeds, so if it remains on, then my earlier suggestion of leaving Snow Mode on all the time there is a slippery surface stands.

 

My understanding is this..

Under "normal" conditions the G37X AWD will be in rear wheel drive mode until slippage is detected, then distributes torque to the front wheels as needed..

Using the "SNOW" mode, is like a manual AWD, where torque is equally distributed to all 4 wheels at the same time..

Thats why its recommended for use in parking or getting started in snowy/icy conditions & for stop/go traffic....

 

Hey GT-R: can you tell me where you found this description of the snow mode? I've looked in a bunch of places but couldn't find anything this detailed nor concise. Thanks!

 

I live in Canada (near Toronto) and purchased my G37xS in November 09. I purchased new rims and snows and defied old man winter to send his worst.
Well guess what,we have had the most mild winter in memory up here (maybe 4 inches of snow just once!)
Very disappointed I haven't been able to test out the 'x' on my new car,but happy I didn't have to shovel either.

By the way,I purchased the Dunlop snows 3D's.They are high performance for a snow (up to 130 mph)and handle great in the dry.(not squishy some some others ie Blizzaks)

Maybe I'll report back next winter,or sometimes we get blasted in early April?

 

That's because it's a spammer. In another thread a new user copy/pasted my text from an earlier post verbatim and put a bankruptcy lawyer link at the bottom.

Probably would do well to click on the "report" button for those posts.

 

It is from a Nissan technical document, pretty much word for word.

I'll have to see if I can find it.

 

i was thinking of getting rwd, but this winter just happened to be a heavy hitter for our area. so the wife was set on the x. it was even more of an issue for her once the first snow hit this year. i was driving our ford explorer went to turn on 4wd auto mode. nothing. then high and low mode also did not work. the 4wd control module is out. lucky me. $500 repair bill coming up. at least i can put that off based on the x and the reports for it in snow.
