voltage is less than 10 volts, or greater than 18
volts.EBU38290Coolant temperature warning light “ ”
This warning light comes on when the engine
overheats.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

NOTICEECB02040
The engine may overheat if the vehicle is
overloaded. If this happens, reduce the load
to specification.
After restarting, make sure that the warning
light is out. Continuous use while this warn-
ing light is on may cause damage to the en-
gine. YFM70KDXK / YFM70KDHK
If the light comes on during operation, stop the ve-
hicle as soon as it is safe to do so and allow the
engine to cool down for about 10 minutes. (See
page 8-67.)

The warning light comes on in red when the en-
gine is overheating. If the red light comes on, stop
the vehicle as soon as it is safe to do so and allow
the engine to idle for about 10 minutes. If the
warning light does not go off, stop the engine and
allow it to cool. (See page 8-67.)
TIPWhen the key is turned to “ ” (on), the warning
light will come on in purple. EBU29933Fuel level warning light “ ” (YFM70KDXK /
YFM70KDHK)
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.

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
vehicle.
YFM70KDXK / YFM70KDHK
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.

YFM70KPSK / YFM70KPLK
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 4-11). Have a Yamaha
dealer check the self-diagnosis system.
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.
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
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. EBU38280Four-wheel drive indicators
Four-wheel drive indicator light “ ”
(YFM70KDXK / YFM70KDHK)
This indicator light comes on when the drivetrain
is set to “4WD” (four-wheel drive).TIPDue to the synchronizing mechanism in the differ-

Speedometer
The speedometer shows the vehicle’s traveling
speed. The speedometer can be set to “MPH” or
“km/h”. This also changes the odometer and trip-
meter units between miles and kilometers. To
change the display between “MPH” and “km/h”,
turn the key to “ ” (off), then while holding the
“SELECT” button pushed, turn the key to “ ”
(on). Odometer and tripmeters
The odometer shows the total distance traveled
by the vehicle.
The tripmeters show the distance traveled since
they were last reset. The tripmeters can be used to
record the distance traveled on a single trip, or to
estimate the distance that can be traveled with a
full tank of gas, etc. The service tripmeter shows
the distance traveled since it was reset at the last
maintenance.

Coolant temperature display
When the coolant is in the normal operating tem-
perature range, the temperature is displayed.
When the coolant temperature rises, the coolant
temperature display will begin to flash. If the cool-
ant temperature continues to rise, the message
“Hi” will flash. TIP
The coolant temperature display can be set to
“°C” or “°F”. To switch the temperature units,
turn the key to “ ” (off), then while holding the
“RESET” button pushed, turn the key to “ ”
(on).
The radiator fan turns on and off automatically
according to the coolant temperature.
Fuel gauge
The fuel gauge indicates the amount of fuel in the
fuel tank. The display segments of the fuel gauge
disappear from “F” (full) towards “E” (empty) as
the fuel level decreases. When the last segment
starts flashing, approximately 4.0 L (1.06 US gal,
0.88 Imp.gal) of fuel remains. Refuel as soon as
possible.
