General Information

The "Automatic on Demand" four wheel drive feature, on
this vehicle, does not require operator activation. The
front wheel drive is not engaged (no power delivered to
front wheels) until the rear wheels begin to lose traction.
The bidirectional clutch senses the rear wheels slipping,
engages the front wheel drive, and delivers power to the
front wheels. The four wheel drive system continues to
deliver power to the front wheels until the rear wheels

have enough traction to move the vehicle without slip-
ping. Once this occurs, the system stops delivering pow-
er to the front wheels and the handling characteristics
become similar to that of a two wheel drive vehicle. The
four wheel drive system functions in both forward and
reverse. When front wheels are turned, the rear wheels
will slip slightly more before power is delivered to the
front wheels.
