EBU34560Coolant temperature warning light “ ”
This warning light comes on when the engine
overheats. 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.
The electrical circuit of the warning light can be
checked by turning the key to “ ” (on). The
warning light should come on for a few seconds,
and then go off.
If the warning light does not come on initially when
the key is turned to “ ” (on), or if the warning
light remains on, have a Yamaha dealer check the
electrical circuit.NOTICEECB02400The engine may overheat if the ATV is over-
loaded. In this case, reduce the load to spec-
ification.
The engine may also overheat if mud or dirt
has accumulated on the radiator (i.e., after
riding in wet terrain). In this case, have a
Yamaha dealer clean the radiator.
Start the engine after making sure that the
warning light is out. Continuous use while
the warning light is on may cause damage to
the engine.
EBU30482Engine trouble warning light “ ”
This warning light comes on or flashes when an
electrical circuit monitoring the engine is not work-
ing correctly. When this occurs, have a Yamaha
dealer check the self-diagnosis system. (See page
4-7 for an explanation of the self-diagnosis de-
vice.)
The electrical circuit of the warning light can be
checked by turning the key to “ ” (on). The
warning light should come on for a few seconds,
and then go off.
If the warning light does not come on initially when
the key is turned to “ ” (on), or if the warning
light remains on, have a Yamaha dealer check the
electrical circuit.

EBU30571Electric Power Steering warning light “EPS”
(for EPS model)
This warning light comes on when the key is
turned to “ ” (on), and then goes off once the
engine is started. If the warning light remains on or
comes on after the engine is started, the EPS sys-
tem 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.TIPIf 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.TIPDue 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.

4Self-diagnosis device
This model is equipped with a self-diagnosis de-
vice for various electrical circuits.
If a problem is detected in any of those circuits,
the engine trouble warning light will come on or
flash and the multi-function display will indicate an
error code.
If the multi-function display indicates an error
code, note the code number, and then have a
Yamaha dealer check the vehicle.
NOTICEECB00812If the multi-function display indicates an error
code, the vehicle should be checked as soon
as possible in order to avoid engine damage. EBU18065Handlebar switches

EBU18081Engine stop switch “ / ”
Set this switch to “ ” before starting the engine.
The engine stop switch controls the ignition and
stops the engine when it is running. Use this
switch to stop the engine in an emergency situa-
tion. The engine will not start or run when this
switch is set to “ ”.EBU18102Start switch “ ”
Push this switch to crank the engine with the start-
er. See the starting instructions on page 6-1 prior
to starting the engine.EBU34120Light switch “ / /OFF”
Set this switch to “ ” to turn on the left and right
headlights (low beams) and the taillight. Set the
switch to “ ” to turn on the left and right head-
lights (high beams), the center headlight, and the
taillight. Set the switch to “OFF” to turn off all the
lights.NOTICEECB00044Do not use the headlights with the engine
turned off for an extended period of time, oth-
erwise the battery may discharge to the pointthat the starter motor will not operate properly.
If this should happen, remove the battery and
recharge it. (See page 8-54.)

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
differential gear is locked, the differential gear lock
indicator light “DIFF. LOCK” will come on along
with the indicator “ ” in the multi-function dis-
play. To unlock the differential gear, stop the ATV and
push the switch to the “4WD” position.
TIP
When the switch is set to “LOCK” or “4WD”, the
differential gear lock indicator and indicator light
will flash until the differential gear is completely
locked or unlocked.
When the indicator and indicator light are flash-
ing, turning the handlebar back and forth will
help the differential gear lock to engage or dis-
engage.

Riding before the differential gear is properly en-
gaged or disengaged (e.g., when the indicator
and indicator light are flashing) will cause the
vehicle speed to be limited until the differential
gear is completely engaged or disengaged.
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 dif-
ferential gear lock speed limiter. (See page 4-8
for a detailed explanation of this switch.)
EBU18283Throttle leverOnce the engine is running, pushing the throttle le-
ver 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 throttle lever is re-
leased. 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.
EBU18324Speed limiterYour ATV is equipped 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 available and the maximum speed of the ATV,
turn the adjusting screw in direction (a). To1. Throttle lever

EBU18757FuelMake sure there is sufficient gasoline in the tank.
WARNING
EWB02522Gasoline and gasoline vapors are extremely
flammable. To avoid fires and explosions and
to reduce the risk of injury when refueling, fol-
low these instructions. 1. Before refueling, turn off the engine and besure that no one is sitting on the vehicle. Nev-
er refuel while smoking, or while in the vicinity of sparks, open flames, or other sources of
ignition such as the pilot lights of water heat-
ers and clothes dryers.
2. Do not overfill the fuel tank. When refueling, be sure to insert the pump nozzle into the fuel
tank filler hole. Stop filling when the fuel
reaches the bottom of the filler tube. Because
fuel expands when it heats up, heat from the
engine or the sun can cause fuel to spill out of
the fuel tank.1. Fuel tank cap
