Re: What does snow mode do?

I'm curious. How does all that front plastic fascia hold up plowing through deep snow in the JGC? Especially on the SRT models? It doesn't look like very much clearance. Has anyone broken any of it?

Re: What does snow mode do?

Here in central Ontario snow mode works well for me during slippery or snow covered road conditions. Wheel spins off corners is minimized and Jeep is quite stable. Lose a lot of that "I'm gonna slide into the ditch any minute" feeling. And yes it obviously is enhanced by decent snow-rated tires. My Dura Tracs perform as expected although they probably are not the best choice on ice.
Just a reminder for anyone new to Jeeps (or any other AWD / 4WD) that although these rigs are very capable and can make their way through some pretty nasty road conditions, some common sense and caution is still mandatory to ensure you "keep the shiny side up" ! Seems like everytime there is a news report on TV about bad weather, they always have a shot of some guy in his nice new Explorer or whatever laying on its side in a ditch. This coming from a guy who 10 yrs ago dumped a Jeep Liberty end over end into a field. Hell of a ride...now I know what those Nascar guys experience when they barrel roll. On the upside, our Jeep gave her life for us, and wifey and I walked away without a scratch.

Re: What does snow mode do?

I had a Commander with quadra trac 2 prior to owning my Grand Cherokee and it only had an auto mode (w/4lo) I never had to figure out what mode to place it in I just drove and it adapted. I liked that better than trying to figure out what mode I need for certain terrain. I occasionally drive on steep loose gravel and not sure what mode to use. Also don't know what mode to use on steep loose dirt or slick mud. (not deep mud but slick dirt road mud) I don't know what this new quadra trac 2 does that the auto stick didn't do on my Commander.

I know what you mean -- sometimes fewer choices is better than more choices. I think the general consensus is that Auto mode does a good job all around under most conditions. But if you know for sure you can choose. There is a chart in the manual (and posts on this website) describing the mode differences.

Re: What does snow mode do?

I have yet to try out any of the modes. I just leave it in Auto and let it do its thing.

On the standard WK2 Overland, haven't had any problems when we get the infamous "only 1-3 inches" where they missed it by a decimal point. Deep snow on the back country mountain roads seems to rub enough to keep the front sensors and ACC clean.

Highway driving where de-icer has been used but the stuff just freezes on hitting the vehicle tends to take out the ACC and front and rear sensors in just a few miles, plus make it impossible to lower to park mode when stopping.

Re: What does snow mode do?

How fast can you go in snow mode? I know with traditional 4WD systems you shouldn't drive on dry pavement with 4WD engaged but the WK2 has a couple different modes. Can you drive normal speeds with snow mode engaged if it's just raining out? Will that damage the 4WD at all or will it be ok?

Re: What does snow mode do?

I've used snow mode at highway speeds with no issues. Torque is split 50/50 but nothing is locked.

Don't forget to lower your tire pressure a bit from those higher summer road trip psi levels - especially with the OEM Michelins. I remembered the hard way.

No limit specified in O.M.
I've done extended freeway cruising which speeds up to 80-90 for long periods without bothering to drop out of snow mode.

You can drive with snow mode on even if it is just raining. It doesn't check temperature to block snow mode... yet. Don't know why you'd do that unless you have really crappy tires or the rain is west coast rain forest levels.

Snow mode really doesn't do anything to 4wd like locking it etc. Changes torque split a bit.
