trical accessories are added.
WARNING
EWB00073Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon monoxide,
a deadly gas. Breathing carbon monoxide can
cause headaches, dizziness, drowsiness, nau-
sea, confusion, and eventually death.
Carbon Monoxide is a colorless, odorless,
tasteless gas which may be present even if you
do not see or smell any engine exhaust. Deadly
levels of carbon monoxide can collect rapidly
and you can quickly be overcome and unable
to save yourself. Also, deadly levels of carbon
monoxide can linger for hours or days in en-
closed or poorly ventilated areas. If you experi-
ence any symptoms of carbon monoxide
poisoning, leave the area immediately, get
fresh air, and SEEK MEDICAL TREATMENT.

Do not run engine indoors. Even if you try to
ventilate engine exhaust with fans or open
windows and doors, carbon monoxide can
rapidly reach dangerous levels. 
Do not run engine in poorly ventilated or par-
tially enclosed areas such as barns, garages,
or carports.
 Do not run engine outdoors where engine
exhaust can be drawn into a building through
openings such as windows and doors.

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.
