4tem may not be working correctly. When this oc-
curs, have a Yamaha dealer check the EPS
system.
The electrical circuit of the warning light can be
checked by turning the key to “ ” (on). If the
warning light does not come on, have a Yamaha
dealer check the electrical circuit.
TIP
If the engine is stopped using the engine stop
switch and the key is in the “ ” (on) position,
the EPS warning light comes on to indicate that
the power assistance for the steering is not
functioning.
If the steering load is too heavy (i.e., excessive
steering use when the ATV is traveling at a slow
speed), the power assist is reduced to protect
the EPS motor from overheating. EBU30451On-Command four-wheel-drive indicator “ ”,
On-Command differential gear lock
indicator “ ” and indicator light “DIFF. LOCK”
The On-Command four-wheel-drive indicator “ ”
comes on when the On-Command four-wheel-
drive switch is set to the “4WD” position. The On-Command differential gear lock
indicator “ ” and the On-Command differential
gear lock indicator light “DIFF. LOCK” come on
when the On-Command differential gear lock
switch is set to the “LOCK” position.
TIP
Due to the synchronizing mechanism in the dif-
ferential gear case, the four-wheel-drive indica-
tor may not come on until the ATV starts
moving.
When the On-Command differential gear lock
switch is set to “LOCK” or “4WD”, the
indicator “ ” and the indicator light “DIFF.
LOCK” will flash until the differential gear is
completely locked or unlocked. If the indicator
and the indicator light continue to flash, the dif-
ferential is not completely locked or unlocked.
In this case, start moving to allow time for the
differential to lock or unlock.

starter will not have enough power to crank the
engine. If this should happen, remove the bat-
tery and recharge it. (See page 8-53.)
EBU18171Horn switch “ ”
Press the switch to sound the horn.EBU18192Override switch “OVERRIDE”
Top speed is normally limited when operating in
differential gear lock. If conditions require more
engine power when riding forward, push and hold this switch to override the differential gear lock
speed limiting function. (See page 4-11.) Releas-
ing the switch restores the speed limiting function.
While the override switch is pushed, the segments
of the speedometer digits will appear as shown in
the figure.
TIPIf the digits of the speedometer appear as shown
when the switch is NOT being pushed, this could
indicate a malfunction in the electrical system. In
this case, take the ATV to a Yamaha dealer at the
first opportunity.

WARNING
EWB00151Always 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. EBU26608On-Command four-wheel-drive switch
“2WD”/“4WD”
WARNING
EWB00164Always 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-wheel
drive to four-wheel drive or vice versa while
moving may cause the ATV to unexpectedlyhandle differently. This could distract the oper-
ator and increase the risk of losing control and
of causing an accident.
This ATV is equipped with a switch to change from
two-wheel drive to four-wheel drive and vice ver-
sa. Select the appropriate drive according to the
terrain 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. Then, the four-wheel-drive
indicator “ ” comes on in the multi-function dis-
play.
To change from four-wheel drive to two-wheel
drive, stop the ATV and push the switch in to the
“2WD” position.

EBU30463On-Command differential gear lock switch
“4WD”/“LOCK”
WARNING
EWB00132Always stop the ATV before changing from
four-wheel drive to four-wheel-drive differen-
tial gear lock or vice versa.
The ATV handles differently in four-wheel drive
than in differential gear lock in some circum-
stances. Changing from four-wheel drive to
differential gear lock or vice versa while mov-
ing may cause the ATV to handle differently un-expectedly. This could distract the operator
and increase the risk of losing control and
causing an accident.
WARNING
EWB00141Always ride at a slow speed when the ATV is in
differential gear lock, and allow extra time and
distance for maneuvers.
All wheels turn at the same speed when the dif-
ferential gear is locked, so it takes more effort
to turn the ATV. The effort needed to turn in-
creases 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 traveling. 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.
