EBU17813Indicator lights and warning light EBU17842Reverse indicator light “”
This indicator light comes on when the transmis-
sion is in the reverse position.Furthermore, this indicator light flashes when the
engine is being raced for 10 seconds or more.
NOTE:If the indicator light flashes under any other circum-
stances or the speedometer does not show the
speed while riding, have a Yamaha dealer checkthe speed sensor circuit.EBU17860Neutral indicator light “”
This indicator light comes on when the transmis-
sion is in the neutral position.EBU17920Coolant temperature warning light “”
This warning light comes on when the engine over-
heats. When this occurs during operation, stop the
engine as soon as it is safe to do so and allow it to
cool down for about 10 minutes.CAUTION:ECB00010
The engine may overheat if the ATV is over-
loaded. In this case, reduce the load to spec-
ification.

gear lock indicator “”/“”
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
“” in the On-Command four-wheel-drive indica-
tor also comes on when the On-Command differ-
ential gear lock switch is set to the “LOCK”
position.NOTE:
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”, the indicator “” willflash until the differential gear is locked.

EBU18040Multifunction display The multifunction display is equipped with the fol-
lowing:
a speedometer (which shows the riding speed)
an odometer (which shows the total distance
traveled)

two tripmeters (which show the distance trav-
eled since they were last set to zero)
a clock
an hour meter (which shows the total time the
key has been turned to “ON”)
a fuel meter
Odometer and tripmeter modes
Pushing the “TRIP/ODO” button switches the dis-
play between the odometer mode “ODO” and the
tripmeter modes “A” and “B” in the following order:
ODO → TRIP A → TRIP B → ODO
To reset a tripmeter, select it by pushing the
“TRIP/ODO” button, and then push the
“TRIP/ODO” button for at least three seconds. The
tripmeters can be used to estimate the distance
that can be traveled with a full tank of fuel. This in-
formation will enable you to plan future fuel stops.
NOTE:Holding in the “TRIP/ODO” button and then turning
the key to “ON” switches the display between“mph” and “km/h”.

Pushing the “”/“” button switches the display
between the clock mode “CLOCK” and the hour
meter mode “HOUR” in the following order:
CLOCK → HOUR → CLOCK
To set the clock
1. Set the display to the clock mode.
2. Push the “”/“” button until the clock starts
flashing.
3. Set the hours by pushing the “H” button.
4. Set the minutes by pushing the “M” button.
5. Push the “”/“” button, and then release it
to start the clock.
Fuel meter
The fuel meter indicates the amount of fuel in the
fuel tank. The display segments of the fuel meter
disappear from “F” (full) towards “E” (empty) as the
fuel level decreases. When the “E” segment disap-
pears and the fuel level warning indicator flashes,
set the fuel cock to reserve and refuel as soon as
possible.

EBU18190Override switch “OVERRIDE”
Top speed is normally limited when operating in
differential gear lock. If conditions require more en-
gine power when riding forward, push and hold this
switch to override the differential gear lock speed
limiting function. (See page 4-9.) Releasing 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.
NOTE:If 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 thefirst opportunity.
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-

EBU18252On-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.
Stop the ATV, move the differential gear lock lever
to position (a), and then push the differential gear
lock switch in to the “LOCK” position. When the dif-
ferential gear is locked, the differential gear lock in-
dicator “DIFF. LOCK” will come on along with the
indicator “” in the multifunction display.1. On-Command four-wheel-drive switch “2WD”/“4WD”

To release the differential gear lock, stop the ATV
and push the switch to the “4WD” position.
WARNING
EWB00130Always 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 dif-
ferential gear lock or vice-versa while moving
may cause the ATV to handle differently unex-pectedly. This could distract the operator and
increase the risk of losing control and causing
an accident.
WARNING
EWB00140Always 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 youare traveling.NOTE:
When the switch is set to “LOCK”, the differential
gear lock indicator and indicator light will flash
until the differential gear is locked.
When the indicator and indicator light are flash-
ing, turning the handlebar back and forth will
help the differential gear lock to engage.

Riding before the differential gear lock is proper-
ly engaged (e.g., when the indicator and indica-
tor light are flashing) will cause the engine speed
to be limited until engagement is complete.
When the ATV is in four-wheel-drive differential
gear lock, the maximum traveling speed is limit-
ed to 35 km/h (22 mi/h). However, if conditions
require full engine power to be available, push
and hold the override switch to disable the differ-
ential gear lock speed limiter. (See page 4-7 fora detailed explanation of this switch.)EBU18280Throttle lever Once the engine is running, movement of the throt-
tle lever will increase the engine speed.
Regulate the speed of the ATV by varying the
throttle position. Because the throttle is spring-
loaded, the ATV will decelerate, and the engine will
return to an idle any time the hand is removed from
the throttle lever.Before starting the engine, check the throttle to be
sure it is operating smoothly. Make sure it returns
to the idle position as soon as the lever is released.
WARNING
EWB00250Malfunction of the throttle could make it diffi-
cult to speed up or slow down when you need
to. This could cause an accident. Check the op-
eration of the throttle lever before you start the
engine. If the throttle does not work smoothly,
check for the cause. Correct the problem be-fore riding the ATV or consult a Yamaha dealer.1. Throttle lever

EBU18321Speed limiter Your ATV was delivered with an adjustable speed
limiter. The speed limiter keeps the throttle from
fully opening, even when the throttle lever is
pushed to the maximum.
1. Loosen the locknut.
2. To increase the maximum engine power avail-
able and the maximum speed of the ATV, turn
the adjusting screw in direction (a). To de-
crease the maximum engine power available
and the maximum speed of the ATV, turn the
adjusting screw in direction (b).3. Tighten the locknut.
WARNING
EWB00240Improper adjustment of the speed limiter and
throttle could cause throttle cable damage or
improper throttle operation. You could lose
control, have an accident or be injured. Do not
turn the adjusting screw out more than 12 mm
(0.47 in) or the throttle cable could be dam-
aged. Always make sure the throttle lever free
play is adjusted to 3.0–5.0 mm (0.12–0.20 in).(See page 8-37.)EBU18391Front brake lever The front brake lever is located on the right handle-
bar. To apply the front brake, pull the brake lever
toward the handlebar grip.
