YFM70KDXJ / YFM70KDHJ
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.
YFM70KPXJ / YFM70KPAJ / YFM70KPHJ /
YFM70KPSJ
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 4-8). 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. EBU37210Four-wheel drive indicators

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 “DIFF. LOCK” indicator light will flash untilthe differential gear is completely locked or un-
locked. Turn the handlebar or start moving to help
the differential lock to engage or disengage.

The multi-function display is equipped with the
following:
speedometer
odometer
two tripmeters
clock
hour meter
fuel gauge
error code display
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 odometer can be used for
maintenance and service intervals. 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.
Push the “SELECT” button to switch between the
odometer “ODO” and the tripmeters “TRIP A” and
“TRIP B” 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 three seconds.
TIP The odometer will lock at 99999.
The tripmeters will reset and continue counting
after 9999.9 is reached. Clock and hour meter
The clock displays time in 12-hour format.
The hour meter shows the total time the engine
has been running.
Push the “CLOCK” button to switch between the
clock “CLOCK” and the hour meter mode
“HOUR” in the following order:
CLOCK → HOUR → CLOCK

4To set the clock
1. Set the display to the clock.
2. Push both the “SELECT” button and “RE-
SET” button for three seconds. The hour dig-
its will start flashing.
3. Push the “RESET” button to set the hours.
4. Push the “SELECT” button, and the minute digits will start flashing.
5. Push the “RESET” button to set the minutes.
6. Push the “SELECT” button and then release it to start the clock.
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 “E” segment
disappears and the fuel level warning indicator
flashes, refuel as soon as possible.TIPThe fuel gauge is equipped with a self-diagnosis
system. If the fuel gauge electrical circuit is not
working correctly, all display segments and the fuel level warning indicator will flash repeatedly. If
this occurs, have a Yamaha dealer check the ve-
hicle.

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.

code, the vehicle should be checked as soon
as possible in order to avoid engine damage. EBU18067Handlebar switchesYFM70KDXJ / YFM70KDHJ
