technique described in this manual on level
ground. Avoid crossing the side of a steep hill if
possible.
 Always use proper procedures if you stall or roll
backwards when climbing a hill. To avoid stall-
ing, use the proper gear range and maintain a
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
reduce the chance of skidding or sliding out of
control. 
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 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.
 Do not operate your ATV during darkness un-
less it is equipped with a properly functioning
headlight. Off-road riding is inherently danger-
ous and additionally, off-road trails do not have
streetlights to guide you.

EBU19187Auxiliary DC jackNOTICEECB03760Do 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. 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.
