"AUTO LSD" system

(two- wheel drive models)
The "AUTO LSD" system aids traction
by using the traction control system to
control engine performance and braking
when one of the rear wheels begins to
spin.
This system is used only when wheel
spinning occurs in a ditch or on a
rough surface.
This system is effective in case one of
the rear wheels is spinning.
