your vehicle, when obtaining insurance, and when ordering
replacement parts. If your vehicle is stolen, these numbers are essential
to the recovery and identification of your vehicle.
Remove the spare key and store it in a safe place. Your key can be
duplicated only by mating a Polaris key blank with one of your
existing keys. If both keys are lost, the ignition switch must be
replaced. See your Polaris dealer.

Operator Safety
Age Restrictions
This vehicle is an ADULT VEHICLE ONLY. Operation is prohibited
for anyone under 16 years of age.
Know Your Vehicle
As the operator of the vehicle, you are responsible for your personal
safety, the safety of others, and the protection of our environment.
Read and understand your owner’s manual, which includes valuable
information about all aspects of your vehicle, including safe operating
procedures.
Safety Training
When you purchased your new ATV, your dealer offered a hands-on
safety training course that covers all aspects of vehicle safety. You were
also provided with printed materials that explain safe operating
procedures. You should review this information on a regular basis.
If you purchased a used Polaris ATV from a party other than a Polaris
dealer, you can request this free safety training from any authorized
Polaris dealer.
A Polaris ATV is an off-road vehicle. Familiarize yourself with all laws
and regulations concerning the operation of this vehicle in your area.
We strongly advise you to strictly follow the recommended
maintenance program outlined in your owner’s manual. This
preventive maintenance program is designed to ensure that all critical
components on your vehicle are thoroughly inspected at specific
intervals.
WARNING
Failure to follow the warnings contained 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 precautions.
Read and understand your owner’s manual and all warnings
before operating a Polaris ATV.
