WARNING
EWB00150Always ride at a slow speed when the ATV is in
four-wheel-drive differential gear lock, and al-
low extra time and distance for maneuvers.
All wheels turn at the same speed when the dif-
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.EBU28430On-Command four-wheel-drive switch
“2WD”/“4WD”
This ATV is equipped with a switch to change from
two-wheel drive to four-wheel drive and vice-versa.
Select the appropriate drive according to the ter-
rain and the conditions.
“2WD” (two-wheel drive): Power is supplied to
the rear wheels.
“4WD” (four-wheel drive): Power is supplied to
the rear and front wheels.To change from two-wheel drive to four-wheel
drive, stop the ATV and push the switch in to the
“4WD” position. The four-wheel-drive indicator
light “” comes on.
To change from four-wheel drive to two-wheel
drive, stop the ATV and push the switch in to the
“2WD” position.
WARNING
EWB00161Always stop the ATV before changing from
two-wheel drive to four-wheel drive and vice-
versa. The ATV handles differently in two-
wheel drive than in four-wheel drive in some
circumstances. Changing from two-wheel1. On-Command four-wheel-drive switch “2WD”/“4WD”

4 drive to four-wheel drive or vice-versa while
moving may cause the ATV to unexpectedly
handle differently. This could distract the oper-
ator and increase the risk of losing control and
of causing an accident.EBU28370On-Command differential gear lock switch
“4WD”/“LOCK”
This ATV is equipped with a switch allowing you to
lock the differential gear when in four-wheel drive.
Select the appropriate switch position according to
the terrain and the conditions.
“4WD” (four-wheel drive): Power is supplied to
the rear and front wheels.
“LOCK” (four-wheel drive with the differential
gear locked): Power is supplied to the rear and
front wheels and the differential gear is locked.
Unlike in four-wheel drive, all wheels turn at the
same speed.To lock the differential gear in four-wheel drive,
make sure the On-Command four-wheel-drive
switch is pushed in to the “4WD” position.
