1nition such as the pilot lights of water heat-
ers and clothes dryers. Gasoline can catch
fire and you could be burned.
When transporting the ATV in another vehi-
cle, be sure it is kept upright. Otherwise, fuel
may leak out of the fuel tank.Gasoline is poisonous. If you should swal-
low some gasoline or inhale a lot of gasoline
vapor, or get some gasoline in your eyes,
seek medical help immediately. If gasoline
spills on your skin, wash with soap and wa-
ter. If gasoline spills on your clothing,change your clothes.
WARNING
EWB00070Always operate your ATV in an area with ade-
quate ventilation. Never start or run the engine
in a closed area. Exhaust fumes are poisonous
and may cause loss of consciousness anddeath within a short time.U3B462E0.book Page 4 Tuesday, March 20, 2007 11:46 AM

EBU26692Indicator lights and warning lights
EBU17830Reverse indicator light “”
This indicator light comes on when the transmis-
sion is in the reverse position.EBU17860Neutral indicator light “”
This indicator light comes on when the transmis-
sion is in the neutral position.EBU28662Coolant 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.
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.CAUTION:ECB00891The 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, see page
8-19 for an explanation on how to access 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 tothe engine.EBU27280Engine trouble warning light “”
This warning light comes on or flashes when an
electrical circuit monitoring the engine is defective.
When this occurs, have a Yamaha dealer check
the self-diagnosis system. (See page 4-5 for an ex-
planation of the self-diagnosis device.)
The electrical circuit of the warning light can be
checked by turning the key to “ON”. If the warning
light does not come on, then go off, have a
Yamaha dealer check the electrical circuit.EBU27542Electric 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 be
defective. When this occurs, have a Yamaha deal-
er 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.
NOTE: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 protectthe EPS motor from overheating.EBU17961On-Command four-wheel-drive/differential
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.

4 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 4-8 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.

WARNING
EWB00400Always adjust the shock absorber assemblies
on the left and right side to the same setting.
Uneven adjustment can cause poor handling
and loss of stability, which could lead to an ac-cident.EBU19180Auxiliary DC jack The auxiliary DC jack is located at the front right
side of the ATV. The auxiliary DC jack can be used
for suitable work lights, radios, etc. The auxiliary
DC jack should only be used when the engine is
running.
1. Set the light switch to “OFF”.
2. Start the engine. (See page 6-1.)
3. Open the auxiliary DC jack cap, and then in-
sert the accessory power plug into the jack.

OPERATION
EBU19900Read the Owner’s Manual carefully before riding
the ATV.
WARNING
EWB00630Read 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. If there is a control or func-
tion you do not understand, ask your Yamahadealer.EBU27342Starting the engine
WARNING
EWB00640Always make sure all control cables work
smoothly before you begin riding in cold
weather. If the control cables are frozen or do
not work smoothly, you could be unable to
control the ATV, which could lead to an acci-dent or collision.
CAUTION:ECB00150See the “Engine break-in” section on page 6-4prior to operating the engine for the first time.
1. Turn the main switch to “ON” and the engine
stop switch to “”.CAUTION:ECB00822The coolant temperature warning light and en-
gine trouble warning light should come on,
then go off.
The EPS warning light should come on, then
go off when the engine is started.
If a warning light does not go off, see page 4-2
for the corresponding warning light circuitcheck.
2. Apply the brake pedal, and then shift the drive
select 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.
