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.

4The ATV handles differently in four-wheel drive
than in differential gear lock in some circum-
stances. Changing from four-wheel drive to
differential gear lock or vice versa while mov-
ing may cause the ATV to handle differently un-
expectedly. This could distract the operator
and increase the risk of losing control and
causing an accident.
To access the “4WD/LOCK” switch, set the
“2WD/4WD” switch to “4WD”, and then move the
drive switch lock lever to the right.
TIP
When the switch is set to “LOCK”, the differen-
tial gear lock indicator light will flash until the dif-
ferential gear is completely locked or unlocked.
 When the indicator light is flashing, turning the
handlebar back and forth will help the differen-
tial gear lock to engage or disengage.
 Riding before the differential gear is properly en-
gaged or disengaged (e.g., when the indicator
light is 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.)
WARNING
EWB00141Always ride at a slow speed when the ATV is in
differential gear lock, and allow extra time and
distance for maneuvers.

EBU37980Fuel tank capRemove the fuel tank cap by turning it counter-
clockwise.
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

EBU19186Auxiliary DC jack
NOTICEECB03760Do not use any single electrical accessory or
combination of accessories that require more
than the stated capacity at any one time. This
may overload the circuit and cause the fuse to
blow. TIPWhen using a winch or other electrical accesso-
ries, the power taken from the DC jack must be re-
duced accordingly. A 12-V accessory, such as a work light or radio
with the proper adapter, can be used when the
main switch is turned on. However, to prevent bat-
tery drain, use when the engine is running and the
headlights are turned off.1. Start the engine.
2. Turn the headlights off.
3. Turn the accessory off.
4. Open the auxiliary DC jack cap.
5. Insert the accessory power plug into the jack.
6. Turn the accessory on.
