On-command four-wheel drive and differential
gear lock switches
This ATV is equipped with an on-command four-
wheel drive switch “2WD”/“4WD” and a differential
gear lock switch “4WD”/“LOCK”. Select the appro-
priate drive according to terrain and the conditions.

Two-wheel drive (2WD): Power is supplied to
the rear wheels only.


Four-wheel drive (4WD): Power is supplied to
the rear and front wheels.


Four-wheel drive with the differential gear
locked (4WD-LOCK): Power is supplied to the
rear and front wheels when the differential gear
is locked (“DIFF.LOCK”). Unlike the 4WD
mode, all wheels turn at the same speed.WARNING
_ Always stop the ATV before changing from 2WD
to 4WD, or from 4WD to 4WD-LOCK, or vice-ver-
sa.
The ATV handles differently in 2WD than in 4WD
and in 4WD-LOCK in some circumstances.
Changing from 2WD to 4WD, or from 4WD to
4WD-LOCK, or vice-versa while moving may
cause the ATV to unexpectedly handle different-
ly. This could distract the operator and increase
the risk of losing control and an accident. _
