Which setting for freezing rain?

Well, looks like I'm driving home tonight in a freezing rain storm. I have a half hour drive on the hwy. and then 10 minutes through town to get home. Fortunately I have already put my winter tires on but I was wondering if there would be any advantage to using "snow" mode over "auto" mode in these conditions. There's no snow just ice covered roads.
I know "snow" mode will start you off in 2nd gear but would it be an advantage to leaving it in "snow" for the hwy part of my trip? It looks like it's going to be a real mess here tonight.

Re: Which setting for freezing rain?

If I recall from last winter, the car felt better on the hwy in Snow mode especially when changing lanes. I would think you would fair better in both snow or ice using the snow mode.
You can always shift on the fly and feel for yourself.

Re: Which setting for freezing rain?

From the manual;


Snow
– Tuning set for additional stability in inclement
weather. Use on and off road on loose traction surfaces
such as snow. When in Snow mode (depending on
certain operating conditions), the transmission may
use second gear (rather than first gear) during
launches, to minimize wheel slippage. If equipped
with air suspension, the level will change to Normal
Ride Height (NRH) if the transfer case is in high range.
The level will change to Off-Road 1 if the transfer case is in Low range.

It doesn't look like there is anything wrong with using auto mode in icy conditions, but the system may take more time to adapt to those conditions versus snow mode.

Re: Which setting for freezing rain?

If I'm correct, snow mode also distributes constant power 50/50 front rear instead of adjusting as needed.
I have tried both settings on ice, and I felt snow mode to be much more planted on the road if that makes sense.

Re: Which setting for freezing rain?

I drove home last night for the first time in Freezing Rain conditions.
By the time I got home, the front of the vehicle, including the headlights, were completely obscured by layer of ice.
(not sure how that affected the light pattern to oncoming drivers, but anyway)...
I left the selector in AUTO, and had no problems whatsoever. I'm impressed.
What I did have to do though, was keep the defrost on the windshield as it kept icing up around the edges.
(I couldn't leave it in AUTO as it just wanted to shoot the heat on my feet).

Re: Which setting for freezing rain?

I ended up just leaving it in Auto and had no problems. I do know what you mean about the windshield as mine was freezing up at the edges and at the bottom without the defrost on. The wipers were starting to get covered as well and I'm glad I didn't have a longer drive. I've never had any luck with the rubber covered "winter" wipers so I don't know if they would work any better on the Jeep.
