Four-Wheel Drive; Principle Of Operation; Using Four-Wheel Drive - Ford RANGER 2012 Owner's Manual

PRINCIPLE OF OPERATION

This system is a proactive system. It has
the ability to anticipate wheel slip and
transfer torque to the rear wheels before
slip occurs. Even when wheel slip is not
present, the system is continuously making
adjustments to the torque distribution, in
an attempt to improve straight line and
cornering behavior, both on and off road.
The system automatically turns on every
time you switch the ignition on.
All components of the system are sealed
and do not require maintenance.
