Ice. Which setting to use?

So there was a snowstorm here yesterday. A lot of sleet too and below freezing temps. The snow has turned into blocks off ice.

Is it safe to drive over that? The plow buried my driveway in. I was just thinking of driving over it. That bad for the tires? Put the jeep in snow mode? Rock mode?

Driving over frozen snow? Good luck going over that without leaving your bumper behind, at least clear out the lowest point of your front end before going into it.

I figured as much.

If the ice isn't that high, I would just raise the jeep to the highest setting.

Today is the day I wish I had that option to raise my SUV, my X5 got "stuck" on top of icy snow where the Jeep would have more clearance, took me few minutes to wiggle out of the mess without braking anything.

OR-2 is limited in what you can do... so try OR-1
As for what traction mode, snow is about the closest, but all of this depends on whether your tires can get traction and if the snow is truly now blocks of ice or is still moveable.

The GC, particularly with the V8, can walk thru snow so high comes over the hood in OR-1... IF your tires can keep traction and the snow is willing to be shoved.

Slushy wet snow can drag pretty good, but with decent tires and the v8 you can still drive easily. If it hard freezes, not so much.

If you haven't done a lot of heavy snow driving, may be a good 'snow day' for you.

Re: Ice. Which setting to use?

Snow mode is what I always use on snowy or icy roads. Put it in ORII and select snow mode afterward. It should stay in snow mode. Do you have a skid plate? Just be careful you don't break anything underneath the Jeep.

Re: Ice. Which setting to use?

So how does rock mode work differently than snow mode? The frozen snow here can look like rocks

Re: Ice. Which setting to use?

We had the same snow storm as you here in New Brunswick Canada. I have a 14 Limited Hemi without QL. I didn't clear my driveway out before work. Just drove through the drifts and bank. Have done this numerous times. As long as the bank isnt ice you'll be fine. Jeep pushes right through it. Takes a lot to get it stuck in snow.

Re: Ice. Which setting to use?

I would think ROCK mode is more for off road crawling over large rocks as the Jeep must be in 4WLO range for it to work. I've always used SNOW mode in a variety of snow conditions, including hard frozen piles created from street plowing, and never had a problem.

Re: Ice. Which setting to use?

Rock mode is only available in 4WD Low.

Rock and Snow are both 50/50 front/rear.

***Rock mode turns off ESP (stability control)***. Snow mode uses ESP.

Rock is OR2, Snow is OR1.

As posted above, select the mode, and you can then change the height afterward.

Doesn't "Rock" also lock the center and rear differential? I thought "Snow" still allowed toque bais in the transfer case.
