and you can quickly be overcome and unable
to save yourself. Also, deadly levels of carbon
monoxide can linger for hours or days in en-
closed or poorly ventilated areas. If you experi-
ence any symptoms of carbon monoxide
poisoning, leave the area immediately, get
fresh air, and SEEK MEDICAL TREATMENT.

Do not run engine indoors. Even if you try to
ventilate engine exhaust with fans or open
windows and doors, carbon monoxide can
rapidly reach dangerous levels.
Do not run engine in poorly ventilated or par-
tially enclosed areas such as barns, garages,
or carports.
Do not run engine outdoors where engine
exhaust can be drawn into a building
through openings such as windows and
doors.

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.

EBU30490Multi-function display The multi-function display is equipped with the fol-
lowing:
a speedometer
an odometer
two tripmeters (which show the distance trav-
eled since they were last set to zero)
a clock

an hour meter (which shows the total time the
engine has been running)
a fuel meter
a self-diagnosis device
Odometer and tripmeter modes
Pushing the “ SELECT” button switches the display
between the odometer mode “ ODO” and the trip-
meter modes “ TRIP A” and “ TRIP B ” in the follow-
ing order:
ODO → TRIP A → TRIP B → ODO
To reset a tripmeter, select it by pushing the “SE-
LECT ” button, and then push the “ RESET” button
for at least three seconds. The tripmeters can be
used to estimate the distance that can be traveled
with a full tank of fuel. This information will enable
you to plan future fuel stops.TIPPushing and holding in the “SELECT ” button, and
turning the key to “” (on) while the button is
pushed, switches the display between “mph” and
“ km/h ”.
