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.NOTICEECB00891The engine may overheat if the ATV is over-
loaded. In this case, reduce the load to spec-
ification.

LOCK”
2. Low-range indicator light “L”
3. High-range indicator light “H”

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.
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 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.

indicator“” in the On-Command four-wheel-
drive indicator also comes on when the On-Com-
mand 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”, the indicator“” willflash until the differential gear is locked.EBU17970Park indicator light“”
This indicator light comes on when the transmis-
sion is in the park position.EBU17980High-range indicator light“”
This indicator light comes on when the transmis-
sion is in the high-range position.EBU17990Low-range indicator light“”
This indicator light comes on when the transmis-
sion is in the low-range position.
EBU18001On-Command differential gear lock indicator
light “DIFF. LOCK”
This indicator light and the On-Command differen-
tial gear lock indicator in the display come on when
the On-Command differential gear lock switch is
set to the “LOCK” position.TIPWhen the switch is set to “LOCK”, the On-Com-

TIPIf the digits of the speedometer appear as shown
when the switch is NOT being pushed, this could
indicate a malfunction in the electrical system. In
this case, take the ATV to a Yamaha dealer at thefirst opportunity.
WARNING
EWB00150Always ride at a slow speed when the ATV is in
four-wheel-drive differential gear lock, and al-
low extra time and distance for maneuvers.
All wheels turn at the same speed when the dif-
ferential is locked, so it takes more effort to
turn the ATV. The effort needed to turn increas-es with the riding speed. You may lose control
and have an accident if you cannot make a
sharp enough turn for the speed you are trav-
eling.EBU26605On-Command four-wheel-drive switch
“2WD”/“4WD”
This ATV is equipped with a switch to change from
two-wheel drive to four-wheel drive and vice versa.
Select the appropriate drive according to the ter-
rain and the conditions.“2WD” (two-wheel drive): Power is supplied to
the rear wheels.“4WD” (four-wheel drive): Power is supplied to
the rear and front wheels.
To change from two-wheel drive to four-wheel
drive, stop the ATV and push the switch in to the
“4WD” position. Then, the four-wheel-drive
indicator“” comes on in the multifunction dis-
play.
To change from four-wheel drive to two-wheel
drive, stop the ATV and push the switch in to the
“2WD” position.
