That is what Smart Mode is for. The sensors determine how you are driving and gauge output to shocks, brakes and power accordingly for the immediate future. In other words, if you are driving like a wise grandpa/ma because of a fear of ice, and using steering and brakes sparingly, Smart Mode will help with that by anticipating your next moves. The manual says: "Smart mode selects the proper driving mode among ECO, COMFORT and SPORT by judging the driver's driving habits (i.e. mild or dynamic) from the brake pedal depression or the steering wheel operation." So, when you use Smart Mode during slippery conditions, the car should respond according to your driving "style" and enter the drive mode most suitable to meet slippery conditions: which, I take it, would be a combination of Eco and Comfort.
