EBU28664Coolant 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 warning
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 re-
mains on, have a Yamaha dealer check the electri-
cal 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
8-21 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.EBU27284Engine 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 warning
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 re-
mains on, have a Yamaha dealer check the electri-
cal circuit.EBU29061Electric 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 start-
ed. If the warning light remains on or comes on af-

4ter 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 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 protect
the EPS motor from overheating.EBU29621On-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”, the indicator“” and
the indicator light “DIFF. LOCK” will flash until
the differential gear is locked. If the indicator and
the indicator light continue to flash, the differen-
tial is not locked. In this case, start moving to al-
low time for the differential to lock.

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.
EBU26606On-Command four-wheel-drive switch
“2WD”/“4WD”
WARNING
EWB00163Always stop the ATV before changing from
two-wheel drive to four-wheel drive and vice
versa. The ATV handles differently in two-
wheel drive than in four-wheel drive in some
circumstances. Changing from two-wheel
drive to four-wheel drive or vice versa while
moving may cause the ATV to unexpectedly
handle differently. This could distract the oper-
ator and increase the risk of losing control and
of causing an accident.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”/“LOCK”
WARNING
EWB00131Always stop the ATV before changing from
four-wheel drive to four-wheel-drive differen-
tial gear lock or vice versa.
The ATV handles differently in four-wheel drive
than in differential gear lock in some circum-
stances. Changing from four-wheel drive to dif-
ferential gear lock or vice versa while moving
may cause the ATV to handle differently unex-
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
