The snow mode is your differential lock, splitting power front to rear, should help you/your wife get out of deep snow situations, take it to a parking lot when it snows and switch it on and feel the difference, the AWD does not know it's stuck in snow and when your stepping on the gas to get out, the AWD thinks your slippin on ice and applying the brakes

It actually has AWD. The Highlander/RX are FWD vehicles at heart, with optional open center and rear differentials. Constant power distribution is 25/25/25/25. When a wheel slips, total power delivery drops to 4x as much torque as is required to spin the slipping wheel (which is basically nothing). Traction Control then kicks in, braking the slipping wheel and thus making it more difficult to turn and increasing the overall power delivery as a result.
