The X5 is great in the snow, in both x-drive and earlier versions, subject to tires. If you've addressed that, no issues.

Do not turn DSC off just because it snows. You have the benefits of dynamic stability control when it is on, the default condition. I have turned DSC off to test it, on slippery roads, and there is a marked improvement in stability with it on.

If you do get stuck with no traction when starting off from a standstill, and there is no wheel traction at all, the DSC brakes spinning wheels. If they are all slipping, DSC will then back off the throttle, not going over idle even if you push the accelerator. That is when you can turn DSC off, to allow some wheel slip and try and churn your way out of where you are stuck. Once you are moving again, push the DSC button to turn DSC back on.

Also, if you have to descend a very slippery hill, at low speed, you can use hill descent control (HDC). It will automatically apply brakes on individual wheels to control your descent. You can use your speed control buttons to increase or decrease the HDC speed.

Since the vehicle is new to you, take it on a deserted road or parking lot at first snowfall and play with it, so that you know what to expect.
