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
