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-
ential gear case, the light may not come on until
the ATV starts moving.

light “ ” (YFM70KPXK / YFM70KPAK /
YFM70KPHK / YFM70KPSK / YFM70KPLK)
This icon and this indicator light come on when
the drivetrain is set to “4WD” with the differential
gear locked.TIPWhen the On-Command differential gear lock
switch is set to “LOCK” or “4WD”, the “ ” icon
and the “ ” indicator light will flash until the dif-
ferential gear is completely locked or unlocked.
Turn the handlebar or start moving to help the dif-
ferential lock to engage or disengage.

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.

Push the “SELECT” button to switch between the
odometer “ODO”, the tripmeters “TRIP A” and
“TRIP B”, and the service tripmeter “ ” in the
following order:
ODO
→ TRIP A → TRIP B → → ODO
To reset a tripmeter, set the display to the tripme-
ter you want to reset, then push the “RESET” but-
ton for 2 seconds.
TIP The odometer will lock at 199999.
The tripmeters will reset and continue counting
after 9999.9 is reached.
Clock, hour meter, voltage display and coolant
temperature display
The clock displays time in 12-hour format. The
hour meter shows the total time the engine has
been running. The voltage display shows the bat-
tery voltage. The coolant temperature display
shows the temperature of the coolant.
Push the “MODE” button to switch between the
clock “CLOCK”, the hour meter “HOUR”, the volt-
age display “VOLT”, and the coolant temperature
display “ ” in the following order:1. Clock/Hour meter/Voltage display/Coolant temperature

6. Push the “SELECT” button, and then release it to start the clock. Voltage display
This display shows the battery voltage. If the bat-
tery voltage is less than 10 volts, “Lo” is displayed,
and if the voltage is above 18 volts, “Hi” is dis-
played.NOTICEECB03570If the voltage display indicates “Lo” or “Hi”,
there may be trouble with the battery charging
circuit or the battery may be faulty. If this oc-
curs, have a Yamaha dealer check or repair the
vehicle. 1. Voltage display1

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.
