4Self-diagnosis device
This model is equipped with a self-diagnosis de-
vice for various electrical circuits.
If any of those circuits are defective, the multifunc-
tion display will indicate a two-digit error code.
If the multifunction display indicates such an error
code, note the code number, and then have a
Yamaha dealer check the vehicle.
CAUTION:ECB00810If the multifunction display indicates an error
code, the vehicle should be checked as soonas possible in order to avoid engine damage.

EBU18100Start switch “”
Push this switch to crank the engine with the start-
er.CAUTION:ECB00050See the starting instructions on page 6-1 priorto starting the engine.EBU18151Light switch “//OFF”
Set this switch to “” to turn on the low beams
and the taillight. Set the switch to “” to turn on
the high beams and the taillight. Set the switch to
“OFF” to turn off all the lights.CAUTION:ECB00040Do not use the headlights with the engine
turned off for an extended period of time, oth-
erwise the battery may discharge to the point
that the starter motor will not operate properly.
If this should happen, remove the battery andrecharge it.EBU18170Horn switch “”
Press the switch to sound the horn.
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 4-10.) 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.1. Override switch “OVERRIDE”

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.

cover it with the cap.
CAUTION:ECB00120Do not use accessories requiring more than
the above maximum capacity. This may
overload the circuit and cause the fuse to
blow.If accessories are used without the engine
running or with the headlights turned on, the
battery will lose its charge and engine start-
ing may become difficult.Do not use an automotive cigarette lighter or
other accessories with a plug that gets hotbecause the jack can be damaged.
