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.TIPIf the indicator light flashes under any other circum-
stances or the speedometer does not show the
speed while riding, have a Yamaha dealer check
the speed sensor circuit.EBU17970Park indicator light “”
This indicator light comes on when the transmis-
sion is in the park 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.
NOTICEECB00010
The engine may overheat if the ATV is over-
loaded. In this case, reduce the load to spec-
ification.
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.EBU27543Electric 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 start-
ed. If the warning light remains on or comes on af-
ter the engine is started, the EPS system may not
be working correctly. When this occurs, 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 function-
ing.
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.EBU29621On-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 ”, the indicator “” and
the indicator light “DIFF. LOCK ” will flash until
the differential gear is locked. If the indicator and
the indicator light continue to flash, the differen-
tial is not locked. In this case, start moving to al-
low time for the differential to lock.

OPERATION
EBU19901Read 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
EWB00631Read 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.EBU26545Starting a cold engine NOTICEECB00150See the “Engine break-in ” section on page 6-5
prior to operating the engine for the first time.1. Turn the fuel cock to “ON ”.
2. Turn the key to “ON ” and the engine stop
switch to “”. 3. Shift the drive select lever into the neutral or
park position. The corresponding indicator
light should come on, if it does not come on,
have a Yamaha dealer check the electrical cir-
cuit.
TIPThe engine can be started under the following con-
ditions:
The drive select lever is in the neutral or park po-
sition.
The rear brake lever is applied with the drive se-
lect lever in any position. However, it is recom-
mended to shift into the neutral or park position
before starting the engine.4. Use the starter (choke) in reference to the fig-ure:
Position (1):
Cold engine start with ambient temperature
below 5 ° C (40 °F).
Position (2):
Cold engine start with ambient temperature
between 0 °C (30 ° F) and 30 ° C (90 °F).

EBU20291Starting a warm engine Follow the same procedure as for starting a cold
engine, with the exception that the starter (choke)
is not required when the engine is warm. Instead,
start the engine with the throttle slightly open.EBU20441Operating the drive select lever and
driving in reverse NOTICEECB00170Before shifting, stop the ATV, otherwise the
transmission may be damaged.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.
3. Release the brake pedal, and then open thethrottle lever gradually.
Shifting: Neutral to Reverse and Reverse to

6reverse, make sure there are no people or ob-
stacles behind you. When it is safe to proceed,
go slowly.
1. Bring the ATV to a complete stop.
2. Apply the brake pedal. The drive select lever
cannot be shifted into or from reverse or park
without applying the brake pedal.
3. Shift from neutral to reverse or from reverse to park and vice versa by moving the drive select
lever along the shift guide.
TIP
When in reverse, the reverse indicator light
should come on. If the indicator light does not
come on, have a Yamaha dealer check the elec-
trical circuit.
Due to the synchronizing mechanism in the en-
gine, the indicator light may not come on until the
ATV starts moving.1. Drive select lever

7Select a large, flat, unpaved area to become famil-
iar with your ATV. Make sure that this area is free
of obstacles and other riders. You should practice
control of the throttle, brakes, shifting procedures,
and turning techniques in this area before trying
more difficult terrain.
Shift to the park position and follow the instruction
on page 6-1 to start the engine. Once it has
warmed up you are ready to begin riding your ATV.
With the engine idling, shift the drive select lever
into the low-range position or the high-range posi-
tion. Apply the throttle slowly and smoothly.
The centrifugal clutch will engage and you will start
to accelerate. If the throttle is applied too abruptly,
the front wheels may lift off the ground, resulting in
a loss of directional control. Avoid higher speeds
until you are thoroughly familiar with the operation
of your ATV.
When slowing down or stopping, release the throt-
tle and apply the brakes smoothly and evenly. Im-
proper use of the brakes can cause the tires to lose
traction, reducing control and increasing the possi-
bility of an accident.
NOTICEECB00251Do not shift from low-range to high-range or
vice versa without coming to a complete stop.
Damage to the engine or drive train may occur.TURNING YOUR ATV
WARNING
EWB01771Always follow proper procedures for turning
as described in this Owner
’s Manual. Practice
turning at low speeds before attempting to turn
at faster speeds. Do not turn at speeds too fast
for your skills or the conditions. ATV could go
out of control, causing a collision or overturn.To achieve maximum traction on unpaved surfac-
es, the two rear wheels turn together at the same
speed. Therefore, unless the wheel on the inside
of the turn is allowed to slip or lose some traction,
the ATV will resist turning. A special turning tech-
nique must be used to allow the ATV to make turns
quickly and easily. It is essential that this skill be
learned first at low speed.
