YFM70KPHG / YFM70KPSG)
This indicator light comes on when the transmis-
sion is in the low-range position.EBU17982High-range indicator light “ ” (YFM70KPXG /
YFM70KPHG / YFM70KPSG)
This indicator light comes on when the transmis-
sion is in the high-range position.EBU17861Neutral indicator light “ ”
This indicator light comes on when the transmis-
sion is in the neutral position.EBU17831Reverse indicator light “ ”
This indicator light comes on when the transmis-
sion is in the reverse position.EBU17971Park indicator light “ ”
This indicator light comes on when the transmis-
sion is in the park position.
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 “ ” (YFM70KDXG /
YFM70KDHG)
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.EBU30482Engine 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.
(YFM70KPXG / YFM70KPHG / YFM70KPSG: See
page 4-8 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 remains on, have a Yamaha dealer check the
electrical circuit.
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 “ ”
(YFM70KDXG / YFM70KDHG)
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 “ ” (YFM70KPXG /
YFM70KPHG / YFM70KPSG)
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. On-Command differential gear lock
indicator “ ” and indicator light “DIFF. LOCK”
(YFM70KPSG)
This indicator and indicator light come on when
the On-Command differential gear lock switch is
set to the “LOCK” position.TIPWhen the On-Command differential gear lock
switch is set to “LOCK” or “4WD”, the
indicator “ ” and the indicator light “DIFF. LOCK”
will flash until the differential gear is completely
locked or unlocked. If the indicator and the indica-
tor light continue to flash, the differential is not

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 4-10
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
drive to four-wheel drive or vice versa while
moving may cause the ATV to unexpectedly handle differently. This could distract the oper-
ator and increase the risk of losing control and
of causing an accident.
This vehicle is equipped with a lever to change
from two-wheel drive to four-wheel drive and vice
versa. Select the appropriate drive according to
the terrain and the conditions.
“2WD” (two-wheel drive): Power is supplied to
the rear wheels.
“4WD” (four-wheel drive): Power is supplied to
the rear and front wheels.
To change from two-wheel drive to four-wheel
drive, stop the vehicle and set the lever to the
“4WD” position. Then, the four-wheel-drive indi-
cator light “ ” (YFM70KDXG / YFM70KDHG) or
the four-wheel-drive indicator “ ”
(YFM70KPXG / YFM70KPHG) comes on.
To change from four-wheel drive to two-wheel
drive, stop the vehicle and set the lever to the
“2WD” position.

EBU18757FuelMake sure there is sufficient gasoline in the tank.
WARNING
EWB02522Gasoline and gasoline vapors are extremely
flammable. To avoid fires and explosions and
to reduce the risk of injury when refueling, fol-
low these instructions. 1. Before refueling, turn off the engine and besure that no one is sitting on the vehicle. Nev-
er refuel while smoking, or while in the vicinity of sparks, open flames, or other sources of
ignition such as the pilot lights of water heat-
ers and clothes dryers.
2. Do not overfill the fuel tank. When refueling, be sure to insert the pump nozzle into the fuel
tank filler hole. Stop filling when the fuel
reaches the bottom of the filler tube. Because
fuel expands when it heats up, heat from the
engine or the sun can cause fuel to spill out of
the fuel tank.1. Fuel tank cap
