Re: Snow. How deep?
You do have brake traction control, plenty good to get you through a freak storm. Low range is most useful for serious off road or when the snow is deep enough your bumpers are plowing a considerable amount of snow. Diff lock on the street is not all that useful. Their main advantage is there is no torque transfer delay, i.e. you don't have to wait for the traction control to sense wheel slip. They also put more power to the wheel with traction, helpful up steep slopes where one wheel has traction, but not that useful for routine freak street stuff. Tires is where its at and some driving skill helps.
With brake traction control, you want to mash the throttle and let the system work... unless of course you start moving too fast.
