ungrounded or broken wiring. Visually check
for broken wiring and leaking fuel. Leaking
fuel can be confirmed by the odor of gasoline.
4. Once immediate safety hazards are con- firmed not to exist, you may remove your hel-
met to more closely inspect your vehicle.
Check for external signs of wear, broken
parts, fluid leaks, cracks in the frame, sus-
pension damage, wheel damage, and so on.
Fuel, oil, and coolant usually give off a notice-
able odor.
5. If your vehicle will not restart or if it is unsafe to ride, then turn off all vehicle systems (en-
gine stop switch, main switch, and fuel cock),
and then signal or go for help.
Aftermarket Parts, Accessories, and Modifica-
tions
While you may find aftermarket products similar in
design and quality to genuine Yamaha accesso-
ries, recognize that some aftermarket accessories
or modifications are not suitable because of po-
tential safety hazards to you or others. Installing
aftermarket products or having other modifica-
tions performed to your vehicle that change any of
the vehicle’s design or operation characteristics
can put you and others at greater risk of serious injury or death. You are responsible for injuries re-
lated to changes in the vehicle. Keep the following
guidelines in mind, as well as those found in the
Loading section (page 7-6) when mounting acces-
sories.

Never install accessories that would impair the
performance of your ATV. Carefully inspect the
accessory before using it to make sure that it
does not in any way reduce ground clearance,
limit suspension travel, steering travel or control
operation.
 Accessories fitted to the ATV can create insta-
bility due to improper weight distribution.
 Bulky or large accessories may seriously affect
the stability of the ATV.
 Certain accessories can displace the operator
from his or her normal riding position. This im-
proper position limits the freedom of movement
of the operator and may limit control ability,
therefore, such accessories are not recom-
mended.
 Use caution when adding electrical accesso-
ries. If electrical accessories exceed the capac-
ity of the ATV’s electrical system, an electric
failure could result, which could cause a dan-

EBU39181Winch switch “OUT/IN”
This switch is used when operating the winch
(page 5-22). Read this manual and the Winch
Owner’s Manual completely before operating the
winch switch.EBU18192Override switch “OVERRIDE” (differential gear
lock models)
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 5-11.) 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.
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-

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. Make sure the accessory is powered off.
4. Open the auxiliary DC jack cap.
5. Insert the accessory power plug into the jack.
6. Turn the accessory on.TIP Turn off the accessory before plugging into/un-
plugging from the jack.
 When the auxiliary DC jack is not being used,
cover it with the cap.
