Welcome
Dear Parents:
We believe your children should have the opportunity to enjoy The Way Out experience
along with you. We've provided this owner's manual to assist you and your children in learn-
ing about safe operation and care of your new ATV. Please review the information in this
manual with any child who may operate the ATV. Help your children learn to operate the
ATV with safety as a top priority. Help them also learn to show respect for our environment
and for the rights of others while operating the ATV.
Children differ in skills, physical abilities and judgement. Some children may not be able to
operate an ATV safely. Always supervise your child's use of the ATV, and permit continued
use only if you determine that your child has the ability and maturity to operate the ATV
safely. Never allow a child to operate the ATV without adult supervision.
The preventive maintenance program outlined in this manual is designed to ensure that all
critical components on your child's ATV are thoroughly inspected at various intervals. For
safe and enjoyable operation of the vehicle, be sure to follow all of the instructions and rec-
ommendations in this manual. If you have any questions about the ATV, contact a Polaris
dealer for assistance.

Welcome
Dear Children:
Before you ride your new Polaris ATV, there are some important things that you need to
know. Your parents and Polaris want you to enjoy riding your new ATV, and that's why you
need to read and understand the information in your owner's manual.
Ask your parents to explain anything you don't understand, and pay close attention to the
warnings and instructions you read. Your safety and the safety of others is the most important
thing to think about at all times.
As the driver of the ATV, you must learn how to keep yourself and those around you safe
while you're riding. So read your manual, and then enjoy riding your new Polaris ATV!

Safety
Understand the Warnings
Always follow the age guidelines for your ATV. Never allow a younger child to ride on or
drive the ATV. Make sure all operators have completed an approved ATV safety training
course such as the SVIA RiderCoursesm and understand all warnings and the owner's manual
before driving the ATV.
Know Your ATV Before Riding
Parents must help their children learn the proper and safe way to ride an ATV. Read the
owner's manual with your children before starting the engine for the first time, and review it
with them periodically afterwards.

Safety Training
ATV safety training is a top priority for Polaris. When you purchased your new ATV, your
dealer instructed you on the authorized ATV RiderCoursesm available to you and your eligi-
ble family members. This training is included in the purchase price of your ATV. Polaris
strongly encourages you and your age eligible family members who will be riding the ATV
to take the ATV RiderCoursesm.
In addition, you were provided with printed material and a video or DVD that instructs oper-
ators on safe operating procedures. You should review this information with your child on a
regular basis.
If you purchased a used Polaris ATV, you can take the ATV RiderCoursesm by calling ATV
Enrollment Express at [phone] or by visiting www.atvsafety.org. Purchasers of a
used Polaris ATV will be charged for this training.

Safety
WARNING
Failure to follow the warnings in this manual can result in severe injury or death.
A Polaris ATV is not a toy and can be hazardous to operate. This vehicle handles differently than
other vehicles such as motorcycles and cars. A collision or rollover can occur quickly, even during
routine maneuvers like turning, or driving on hills or over obstacles, if you fail to take proper precau-
tions.
Read and understand the owner's manual and all warnings before operating a Polaris ATV.

Safety
• Read this manual and all labels carefully.
Follow all operating procedures.
• Never operate an ATV without proper
instruction. Take a training course. Pur-
chasers of a new Polaris ATV and age eli-
gible family members are entitled to take
the ATV RiderCoursesm. Contact ATV
Enrollment Express at [phone] or
visit www.atvsafety.org for information
on enrollment in the ATV RiderCoursesm.
• Always follow the age guidelines for
your vehicle: Y-12 90cc models are
designed for children not less than 12
years of age and Y-6 50cc models are
designed for children not less than 6 years
of age. No child under the age of 16
should ride any ATV designed and sold
for an adult.
• Do not allow other children to ride this
ATV unless they have read the manual,
seen the instructional video or DVD and
taken and completed an approved ATV
safety training course such as the ATV
RiderCoursesm.
• Always avoid operating an ATV on any
paved surfaces, including sidewalks,
driveways, parking lots and streets.
• Never operate an ATV on any public
street, road or highway, including dirt or
gravel roads.
• Always be sure there are no obstacles or
people behind your ATV when operating
in reverse. Drive slowly and avoid turn-
ing at sharp angles in reverse.

11
Safety
• Never operate an ATV without wearing
an approved helmet that fits properly.
Always wear eye protection (goggles or
face shield), gloves, boots, a long-sleeved
shirt or jacket, and long pants.
• Never consume alcohol or drugs before
or while operating this ATV.
• Never operate at excessive speeds.
Always travel at a speed which is proper
for the terrain, visibility and operating
conditions, and your experience.
• Never attempt jumps or other stunts.
• Never tow or pull an object behind the
ATV.
• Always inspect your ATV each time you
use it to make sure it is in safe operating
condition. Always follow the inspection
and maintenance procedures and sched-
ules described in this manual.
• Always keep both hands on the handle-
bars and both feet on the footrests of the
ATV during operation.
• Always go slowly and be extra careful
when operating on unfamiliar terrain.
Always be alert to changing terrain con-
ditions when operating the ATV.
• Never operate on excessively rough, slip-
pery or loose terrain.

12
Safety
• Always follow proper procedures for
turning as described in this manual. Prac-
tice turning at low speeds before attempt-
ing to turn at faster speeds. Do not turn at
excessive speed.
• Always have the ATV checked by an
authorized Polaris dealer if it has been
involved in an accident.
• Never operate the ATV on hills too steep
for the ATV or for your abilities. Practice
on smaller hills before attempting larger
hills.
• Always follow proper procedures for
climbing hills as described in this manual.
Check the terrain carefully before you
start up any hill. Never climb hills with
excessively slippery or loose surfaces.
Shift your weight forward. Never open
the throttle suddenly or make sudden gear
changes. Never go over the top of any hill
at high speed.
• Always follow proper procedures for
going down hills and for braking on hills
as described in this manual. Check the
terrain carefully before you start down
any hill. Shift your weight backward.
Never go down a hill at high speed. Avoid
going down a hill at an angle which
would cause the vehicle to lean sharply to
one side. Go straight down the hill where
possible.

13
Safety
• Always follow proper procedures for
crossing the side of a hill as described in
this manual. Avoid hills with excessively
slippery or loose surfaces. Shift your
weight to the uphill side of the ATV.
Never attempt to turn the ATV around on
any hill until you have mastered the turn-
ing technique described in this manual on
level ground. Avoid crossing the side of a
steep hill.
• Always use proper procedures if you stall
or roll backwards when climbing a hill.
To avoid stalling, maintain a steady speed
when climbing a hill. If you stall or roll
backwards, follow the special procedure
for braking described in this manual. Dis-
mount on the uphill side or to either side
if pointed straight uphill. Turn the ATV
around and remount, following the proce-
dure described in this manual.
• Always be careful of skidding or sliding.
On slippery surfaces, such as ice, go
slowly and be very cautious in order to
reduce the chance of skidding or sliding
out of control.

14
Safety
• Always check for obstacles before oper-
ating in a new area. Never attempt to
operate over large obstacles, such as
rocks or fallen trees. Always follow
proper procedures when operating over
obstacles as described in this manual.
• Avoid operating the ATV through deep or
fast flowing water. If you cannot avoid
water which exceeds the recommended
maximum depth (see page 106), go
slowly, balance your weight carefully
avoiding sudden movements, maintain a
slow and steady forward motion, do not
make sudden turns or stops, and do not
make sudden throttle changes.
• Wet brakes may have reduced stopping
ability. Test your brakes after leaving
water. If necessary apply them lightly
several times to let friction dry out the
pads.
• Always use the size and type tires speci-
fied in this manual. Always maintain
proper tire pressure as described in this
manual.
• Never modify an ATV through improper
installation or use of accessories.
• Never exceed the stated load capacity for
an ATV.
• Always remove the ignition key when the
vehicle is not in use to prevent unautho-
rized use or accidental starting.

Safety
Equipment Modifications
We are concerned for the safety of our customers and for the general public. Therefore, we
strongly recommend that consumers do not install on a Polaris ATV any equipment that may
increase the speed or power of the vehicle, or make any other modifications to the vehicle for
these purposes. Any modifications to the original equipment of the vehicle create a substan-
tial safety hazard and increase the risk of bodily injury.
The warranty on your Polaris ATV is terminated if any equipment has been added to the
vehicle, or if any modifications have been made to the vehicle, that increase its speed or
power.
NOTE: The addition of certain accessories may change the handling characteristics of the ATV. Use
only Polaris-approved accessories, and familiarize yourself with their function and effect on
the ATV.
