The Auto LSD is not a real LSD but part of the Vehicle Stability Control
> system. The Auto LSD achieves the equivalent functions of an LSD (Limited
> Slip Differential) through the use of a traction control system. When the
> driver presses the Auto LSD switch, this system achieves the LSD effect by
> regulating the hydraulic pressure that acts on the drive wheels and
> controlling the engine output in accordance with the amount of pedal
> effort applied on the accelerator. Auto LSD tends to enhance the
> acceleration effort somewhat, in order to apply greater drive torque to
> the wheel that is making contact with the ground. Thus, this function
> enables the vehicle to get unstuck if a wheel loses its grip, and enhances
> the vehicle's startoff performance on high-resistance surface conditions
> such as gravel roads
