We got 6 inches of snow here in Maryland and I got to use my truck's 4 wheel drive! But have a question.......I read the owners manual on how to engage the "auto", 4x4 high and 4x4 low setting. I see 4x4 lighting up on the dash when I shift into high and low but nothing is illuminated when I'm in the auto setting. Should there be a light on for that setting?
