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. _

Differential gear lock switch “4WD”/“LOCK”
To lock the differential gear in 4WD, make sure the
on-command four-wheel-drive switch is set to
“4WD”, stop the ATV, move the lever to
position
b, and then set the switch to “LOCK”.
When the differential gear is locked, the differential
gear lock indicator light (“DIFF.LOCK”) will come
on along with the indicator “” in the speedometer
unit display. To release the differential gear lock,
stop the ATV and set the switch to “4WD”.

WARNING
_ Always ride at a slow speed when the ATV is in
4WD-LOCK, and allow 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 amount of effort is more the
faster you go. You may lose control and have
an accident if you cannot make a sharp
enough turn for the speed you are traveling. _ NOTE:_

When the switch is set to “LOCK”, the differ-
ential gear lock indicator light will flash until
the differential gear is locked.


When the indicator light is flashing, turning
the handlebar back and forth will help the dif-
ferential gear lock to engage.


Riding before the differential gear lock is
properly engaged (e.g., when the indicator
light is flashing) will cause the engine speed
to be limited until engagement is complete.


When the ATV is in 4WD-LOCK, the maxi-
mum traveling speed is limited to 35 km/h.
