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.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.
EBU17955Four-wheel drive indicator light “ ”
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.

EBU34123Light 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 handlebar-mounted light
(YFM45KPXK / YFM45KPHK / YFM45KPLK), and
the taillight. Set the switch to “OFF” to turn off all
the lights.NOTICEECB00046Do not use the headlights with the engine
turned off for an extended period of time. The
battery may discharge to the point that the
starter will not have enough power to crank the
engine. If this should happen, remove the bat-
tery and recharge it. (See page 8-52.) EBU18171Horn switch “ ”
Press the switch to sound the horn.EBU28434On-Command drive switch “2WD/4WD”
Stop the ATV and push this switch to change from
two-wheel drive to four-wheel drive or vice versa.
Select the appropriate drive according to the ter-
rain and riding conditions.
“2WD” (two-wheel drive): power is supplied to
the rear wheels only, giving a smooth ride and
fuel economy.
“4WD” (four-wheel drive): power is supplied to
the front and rear wheels, giving maximum trac-
tion.
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.

8If an electrical problem is suspected, check the
fuse and replace it if necessary as follows.
NOTICEECB00641To prevent accidental short-circuiting, turn off
the main switch when checking or replacing a
fuse. 1. Turn off all electrical systems. (See page 4-1.) 2. Remove the seat. (See page 4-13.)
3. Remove the blown fuse, and then install a
new fuse of the specified amperage.
WARNING! Always use a fuse of the spec-
ified rating, and never use a substitute ob-
ject in place of the proper fuse. An
improper fuse or a substitute object can
cause damage to the electrical system,
which could lead to a fire.
