EBU30530Coolant 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). The warn-
ing 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 elec-
trical circuit.NOTICEECB00891
The 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
8-20 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 to
the engine.EBU30480Engine trouble warning light “”
This warning light comes on or flashes when an
electrical circuit monitoring the engine is not work-
ing correctly. When this occurs, have a Yamaha
dealer check the self-diagnosis system. (See page
4-7 for an explanation of the self-diagnosis device.)
The electrical circuit of the warning light can be
checked by turning the key to “” (on). The warn-
ing 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 elec-
trical circuit.EBU30570Electric Power Steering warning light “EPS ”
(for EPS model)
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 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 func-
tioning.
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.EBU30450On-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 com-
pletely locked or unlocked. If the indicator and
the indicator light continue to flash, the differen-
tial is not completely locked or unlocked. In this
case, start moving to allow time for the differen-
tial to lock or unlock.

4Self-diagnosis device
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
multi-function display will indicate an error code.
If the multi-function display indicates an error code,
note the code number, and then have a Yamaha
dealer check the vehicle.
NOTICEECB00811If the multi-function display indicates an error
code, the vehicle should be checked as soon
as possible in order to avoid engine damage.
