Andy, VDIM is just that good. With FWD bias, traction control keeps thing contained all the time. I believe lights flash only under harsh interference.

A few weeks ago, I was driving the RX in a heavy snow storm. It was pretty uneventful, particularly since I'm running winter tires on both of my cars now.
I then had to pick up my IS from the parking lot at work. I jumped into the IS, turned off traction control (as I usually do) and gave it gas. That caught me by surprise. By that time, I was used to RX just going going about its business. I had to readjust at how "loose" the car was without VDIM engaged and AWD. A few doughnuts in the parking lot accomplished this task.

Got plenty of snow and unplowed roads this AM. VDIM went about its business, fully transparent, and w/o any indication of its work, other than keeping the vehicle going where intended. It starts beeping and flashing only if it is unable to fulfill driver requests.

Bit of a delay in my question, but relatively new 2011 RX450H driver, living in the SF Bay Area. Heading to Truckee in the Winter in the 450H? Can I do it? What tires would you recommend, or should I skip it and just take the Merc GL450 w/ obviously better 4WD options?

I'm in the market for tires anyway, mainly highway commute, but would want M+S just in case I get up into Truckee in some snow. Thanks for the input.

Welcome to CL, abscam. I'd suggest taking a look at the 3RX tire thread here for recommendations from fellow members. Or check out reviews on CL sponsor Tire Rack. Between the two you can find some great tire recommendations.

Abscam,
Regardless of the tires you choose, when traveling in the Sierras in the winter you will still need to carry chains to be legal, FYI.

Really depends on what you plan to do in the snow as well. Commute = RX450. Real fun in the snow = GL450

I noticed that, in my 2013 450h AWD, Snow Mode kept the rear motor engaged until approximately 27 MPH - and for me, living on a lake and forced to navigate 25 MPH winding roads for about 4 miles as I leave/arrive, I enjoy having AWD engaged while at 25 MPH.

I was (and still am) a little concerned that the Computer Nanny might override my wishes if I ever have the misfortune of running off the road and wanting to simply "GO GO GO" out of trouble; however, here in Michigan's worst winter in a generation this past winter - I never got anywhere close to stuck!

The street just off my driveway is normally not a choice in winter/snow; however I continuously "tested" the car by stopping mid way up the incline on ice/snow and then starting up the hill.

While other Hybrid owners may agree with me that a push on the accelerator is but a mere request (as opposed to an order), the car ALWAYS went slowly up with the hill with barely perceptible wheel spin - regardless of how hard I tromped on the accelerator.

I even stopped many times while descending it and other normally bad choices for road inclines - and stepped on the "request pedal" in reverse - only to have it slowly, but effectively, back up the incline - with little perceptible wheel spin.

My RXh was my first choice over the Dodge 4x4 Ram this past year in snow (except for when I didn't want to get it dirty).

When not in Snow Mode, I found the front wheels more prone to slippage - however, the traction control did effectively take over. Snow Mode was more pleasant a driving experience.

I am very impressed.
