EBU34560Coolant temperature warning light “ ”
This warning light comes on when the engine
overheats. 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 remains on, have a Yamaha dealer check the
electrical circuit.NOTICEECB02400The 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, have a
Yamaha dealer clean 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.
EBU29933Fuel level warning light “ ” (YFM70KDXH)
This warning light comes on when the fuel level
drops below approximately 4.0 L (1.06 US gal,
0.88 Imp.gal). When this occurs, refuel as soon as
possible.
The electrical circuit of the warning light can be
checked by setting the engine stop switch to “ ”
and 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 remains on, have a Yamaha dealer check the
electrical circuit.
EBU27287Engine trouble warning light “ ”
YFM70KDXH
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.
YFM70KPXH / YFM70KPHH / YFM70KPSH /
YFM70KPAH
This warning light comes on or flashes if a problem
is detected in the electrical circuit monitoring the
engine. When this occurs, the display will indicate
an error code (see page 4-9). Have a Yamaha
dealer check the self-diagnosis system.
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 remains on, have a Yamaha dealer check the

EBU30571Electric 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 sys-
tem may not be working correctly. When this oc-
curs, 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.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
functioning.
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.
EBU34250Four-wheel-drive indicator light “ ”
(YFM70KDXH)
This indicator light comes on when the drive lever
is set to the “4WD” position.TIPDue to the synchronizing mechanism in the differ-
ential gear case, the light may not come on until
the ATV starts moving. Four-wheel-drive indicator “ ” (YFM70KPXH /
YFM70KPHH / YFM70KPSH / YFM70KPAH)
This indicator comes on when the drive lever or
the On-Command four-wheel-drive switch is set
to the “4WD” position.TIPDue to the synchronizing mechanism in the differ-
ential gear case, the indicator may not come on
until the ATV starts moving.

Error code display
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 engine trouble warning light will come on or
flash, and the display will indicate an error code.
If the display indicates an error code, note the
code number and have a Yamaha dealer check
the vehicle.
NOTICEECB00812If the multi-function display indicates an error
code, the vehicle should be checked as soon
as possible in order to avoid engine damage. EBU18066Handlebar switchesYFM70KDXH / YFM70KPXH / YFM70KPHH /

To unlock the differential gear, stop the ATV and
push the switch to the “4WD” position.
TIP When the switch is set to “LOCK” or “4WD”, the
differential gear lock indicator and indicator light
will flash until the differential gear is completely
locked or unlocked.
When the indicator and indicator light are flash-
ing, turning the handlebar back and forth will
help the differential gear lock to engage or dis-
engage.
Riding before the differential gear is properly en-
gaged or disengaged (e.g., when the indicator
and indicator light are flashing) will cause the
vehicle speed to be limited until the differential
gear is completely engaged or disengaged.
When the ATV is in four-wheel-drive differential
gear lock, the maximum traveling speed is limit-
ed to 35 km/h (22 mi/h). However, if conditions
require full engine power to be available, push
and hold the override switch to disable the dif-
ferential gear lock speed limiter. (See page 4-11
for a detailed explanation of this switch.)

WARNING
EWB00164Always 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
