1 steady speed when climbing a hill. If you stall or
roll backwards, follow the special procedure for
braking described in this manual. Dismount on
the uphill side or to a side if pointed straight up-
hill. Turn the ATV around and remount, following
the procedure described in this manual.

Always check for obstacles before operating in a
new area.
Never attempt to operate over large obstacles,
such as large rocks or fallen trees. Always follow
proper procedures when operating over obsta-
cles as described in this manual.
Always be careful when skidding or sliding.
Learn to safely control skidding or sliding by
practicing at low speeds and on level, smooth
terrain. On extremely slippery surfaces, such as
ice, go slowly and be very cautious in order to re-
duce the chance of skidding or sliding out of con-
trol.
Never operate an ATV in fast flowing water or in
water deeper than that recommended in this
manual. Remember that wet brakes may have
reduced stopping ability. Test your brakes after
leaving water. If necessary, apply them several
times to let friction dry out the linings.

Always be sure there are no obstacles or people
behind you when you operate in reverse. When
it is safe to proceed in reverse, go slowly.
Always use the size and type of tires specified in
this manual.
Always maintain proper tire pressure as de-
scribed in this manual.
Never modify an ATV through improper installa-
tion or use of accessories.
Never exceed the stated load capacity for an
ATV. Cargo should be properly distributed and
securely attached. Reduce speed and follow in-
structions in this manual for carrying cargo or
pulling a trailer. Allow greater distance for brak-
ing.

spills on your skin, wash with soap and wa-
ter. If gasoline spills on your clothing,change your clothes.

EBU18034Multifunction display The multifunction display is equipped with the fol-
lowing:
a speedometer (which shows the riding speed)
an odometer (which shows the total distance
traveled)
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
key has been turned to “ON”)
Odometer and tripmeter modes
Pushing the “TRIP/ODO” button switches the dis-
play between the odometer mode “ODO” and the
tripmeter modes “A” and “B” in the following order:
ODO → TRIP A → TRIP B → ODO
To reset a tripmeter, select it by pushing the
“TRIP/ODO” button, and then push the
“TRIP/ODO” 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 in-
formation will enable you to plan future fuel stops.TIPPushing and holding in the “TRIP/ODO” button,
and turning the key to “ON” while the button is
pushed, switches the display between “mph” and“km/h”.
Clock mode
Pushing the“/” button switches the display
between the clock mode “CLOCK” and the hour
meter mode “HOUR” in the following order:
