four-wheel-drive differential gear lock, and al-
low extra time and distance for maneuvers.

ferential is locked, so it takes more effort to
turn the ATV. The effort needed to turn increas-
es with the riding speed. You may lose control
and have an accident if you cannot make a
sharp enough turn for the speed you are trav-eling.EBU28431On-Command four-wheel-drive switch
