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.
EBU30483Engine trouble warning light “ ”
This warning light comes on or flashes if a problem
is detected in the electrical circuit monitoring the
engine. When this occurs, the display will indicate
an error code (see page 4-7). Have a Yamaha
dealer check the self-diagnosis system.
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.EBU30511Electric Power Steering warning light “EPS”
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-
U2UD61E0.book Page 3 Monday, April 25, 2016 10:55 AM

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.

Error code display
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 display will indicate an error code.
If the display indicates an error code, note the
code number and have a Yamaha dealer check
the vehicle.

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.
3. Wipe up any spilled fuel immediately.NOTICE: Immediately wipe off spilled fuel
with a clean, dry, soft cloth, since fuel may
deteriorate painted surfaces or plastic
parts.
[ECB00982]
4. Turn the fuel tank cap fully clockwise to make sure it is securely closed.

OPERATION
EBU19902Read the Owner’s Manual carefully before riding
the ATV. If there is a control or function you do not
understand, ask your Yamaha dealer.
WARNING
EWB00632Read the Owner’s Manual carefully to become
familiar with all controls in order to help pre-
vent any loss of control, which could cause an
accident or injury. EBU30502Starting the engineThis model is equipped with an ignition circuit cut-
off system. To enable starting one of the following
conditions must be met:
The drive select lever is in the neutral or park po-
sition.
The rear brake lever or brake pedal is applied.
TIPUnder normal operating conditions, it is recom-
mended to shift into neutral or park and apply the
rear brake when starting the engine. NOTICEECB00151See the “Engine break-in” section on page 6-4
prior to operating the engine for the first time. To start the engine
1. Turn the key to “ ” (on) and the engine stop switch to “ ” (run).
The coolant temperature warning light and
the engine trouble warning light should
come on for a few seconds, then go off.
The electric power steering warning light
should come on and stay on until the en-
gine is started.

NOTICEECB00826To avoid possible damage, do not operate the
ATV if a warning light does not work as de-
scribed above. 2. Apply the brake pedal, then shift the drive se-lect lever into the neutral or park position. The
corresponding indicator light should come
on. If the indicator light does not come on,
have a Yamaha dealer check the electrical
circuit.
3. Apply the rear brake lever or brake pedal.
4. Completely close the throttle lever, then push the start switch to crank the engine with the
starter. Release the start switch when the en-
gine has started.TIPIf the engine fails to start, release the start switch.
Wait a few seconds before the next cranking at-
tempt to allow battery voltage to restore and the
starter motor to cool. Do not crank the engine
more than 10 seconds on any single attempt.
NOTICEECB00164For maximum engine life, never accelerate
hard when the engine is cold! EBU36230Operating the drive select lever and
driving in reverseNOTICEECB03330Do not shift without coming to a complete stop
and waiting for the engine to return to normal
idle speed. Damage to the engine or drivetrain
may occur. Shifting: Neutral to High-range and High-range
to Low-range1. Bring the ATV to a complete stop.
2. Apply the brake pedal, and then shift by mov- ing the drive select lever along the shift guide.TIPMake sure that the drive select lever is completely
shifted into position.
