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

4completely locked or unlocked. In this case, start
moving to allow time for the differential to lock or
unlock.
EBU30495Multi-function display (YFM70KPXG /
YFM70KPHG / YFM70KPSG)
The multi-function display is equipped with the
following:
a speedometer
an odometer
two tripmeters (which show the distance trav-
eled since they were last set to zero)
a clock
an hour meter (which shows the total time the
engine has been running)
a fuel meter
a self-diagnosis device
Odometer and tripmeter modes
Pushing the “SELECT” button switches the dis-
play between the odometer mode “ODO” and the
tripmeter modes “TRIP A” and “TRIP B” in the fol-
lowing order:
ODO → TRIP A → TRIP B → ODO
To reset a tripmeter, select it by pushing the “SE-
LECT” button, and then push the “RESET” button
for at least three seconds. The tripmeters can be
used to estimate the distance that can be traveled
with a full tank of fuel. This information will enable
you to plan future fuel stops.

EBU18102Start switch “ ”
Push this switch to crank the engine with the start-
er. See the starting instructions on page 6-1 prior
to starting the engine.EBU34120Light switch “ / /OFF”
Set this switch to “ ” to turn on the left and right
headlights (low beams) and the taillight. Set the
switch to “ ” to turn on the left and right head-
lights (high beams), the center headlight
(YFM70KPXG / YFM70KPHG / YFM70KPSG),
and the taillight. Set the switch to “OFF” to turn off
all the lights.NOTICEECB00044Do not use the headlights with the engine
turned off for an extended period of time, oth-
erwise the battery may discharge to the point
that the starter motor will not operate properly.
If this should happen, remove the battery and
recharge it. (See page 8-54.) EBU18171Horn switch “ ”
Press the switch to sound the horn.
EBU18192Override switch “OVERRIDE” (YFM70KPSG)
Top speed is normally limited when operating in
differential gear lock. If conditions require more
engine power when riding forward, push and hold
this switch to override the differential gear lock
speed limiting function. (See page 4-12.) Releas-
ing the switch restores the speed limiting function.
While the override switch is pushed, the segments
of the speedometer digits will appear as shown in
the figure.1. Override switch “OVERRIDE”

TIPIf the digits of the speedometer appear as shown
when the switch is NOT being pushed, this could
indicate a malfunction in the electrical system. In
this case, take the ATV to a Yamaha dealer at the
first opportunity.
WARNING
EWB00151Always ride at a slow speed when the ATV is in
four-wheel-drive differential gear lock, and al-
low extra time and distance for maneuvers.
All wheels turn at the same speed when the dif-
ferential is locked, so it takes more effort to
turn the ATV. The effort needed to turn increas-es with the riding speed. You may lose control
and have an accident if you cannot make a
sharp enough turn for the speed you are trav-
eling.
EBU26608On-Command four-wheel-drive switch
“2WD”/“4WD” (YFM70KPSG)
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 ATV is equipped with a switch to change from
two-wheel drive to four-wheel drive and vice ver-
sa. Select the appropriate drive according to the
terrain and the conditions.
“2WD” (two-wheel drive): Power is supplied to
the rear wheels.
