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.

6bulky object attached to the handlebars which
could make steering difficult, an accessory that
limits your ability to move around on the seat, or
one that limits your view.

Use extra caution when riding an ATV with ac-
cessories. The ATV may handle differently than
it does without accessories.EBU27571Loading
WARNING
EWB00820Never exceed the stated load capacity for this
ATV. Overloading this ATV or carrying or tow-
ing cargo improperly could cause changes in
ATV handling which could lead to an accident.
Cargo should be properly distributed and se-
curely attached. Reduce speed when carrying
cargo or pulling a trailer. Allow greater dis-
tance for braking.Cargo or a trailer can change the stability and han-
dling of an ATV.
You must use common sense and good judgment
when carrying cargo or towing a trailer. Keep the
following points in mind:

Never exceed the weight limits shown. An over-
loaded ATV can be unstable.
Do not exceed the maximum tongue weight.
You can measure tongue weight with a bath-
room scale. Put the tongue of the loaded trailer
on the scale with the tongue at hitch height. Ad- MAXIMUM LOADING LIMIT
ATV loading limit (total weight of rider, cargo,
accessories, and tongue):

Shift your weight to the uphill side of the
ATV.
Never attempt to turn the ATV around on any
hill until you have mastered the turning tech-
nique as described in the Owner’s Manual on
level ground. Be very careful when turning
on any hill.Traversing a sloping surface on your ATV requires
you to properly position your weight to maintain
proper balance. Be sure that you have learned the
basic riding skills on flat ground before attempting
to cross a sloping surface. Avoid slopes with slip-
pery surfaces or rough terrain that may upset your
balance.
As you travel across a slope, lean your body in the
uphill direction. It may be necessary to correct the
steering when riding on loose surfaces by pointing
the front wheels slightly uphill. When riding on
slopes, be sure not to make sharp turns either up
or down hill.
If your ATV does begin to tip over, gradually steer
in the downhill direction if there are no obstacles in
your path. As you regain proper balance, gradually
steer again in the direction you wish to travel.CROSSING THROUGH SHALLOW WATER
WARNING
EWB01641Operating this vehicle through deep or fast-
flowing water can lead to loss of control or an
overturn. To reduce your risk of drowning or
other injuries, use care when crossing through
water. Never operate this ATV water deeper
than the depth specified in your Owner’s Man-
ual, as tires may float, increasing the risk of an
overturn.

7 If the rear wheels of your ATV start to slide side-
ways, control can usually be regained (if there is
room to do so) by steering in the direction of the
slide. Applying the brakes or accelerating is not
recommended until you have corrected the slide.With practice, over a period of time, skill at con-
trolled sliding can be developed. The terrain
should be chosen carefully before attempting such
maneuvers, since both stability and control are re-
duced. Bear in mind that sliding maneuvers should
always be avoided on extremely slippery surfaces
such as ice, since all control may be lost.
WHAT TO DO IF...
This section is designed to be a reference guide
only. Be sure to read each section on riding tech-
niques completely.
