available to you and your eligible family members. This training is
included in the purchase price of your ATV. 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 in the United States, you can
enroll in the ATV RiderCoursesm for a fee. Call ATV Enrollment
Express at [phone] or visit www.atvsafety.org.
If you purchased a POLARIS ATV outside the United States, please
contact your dealer or local law enforcement agencies for information
about safety training.
This POLARIS vehicle 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 vehi-
cle are thoroughly inspected at specific intervals.

SAFETY
Safe Riding Gear
Eye Protection
Do not depend on eyeglasses or sunglasses for eye protection. When-
ever riding a POLARIS vehicle, always wear shatterproof goggles or
use a shatterproof helmet face shield. POLARIS recommends wearing
approved Personal Protective Equipment (PPE) bearing markings such
as VESC 8, V-8, Z87.1, or CE. Make sure protective eye wear is kept
clean.
Gloves
Off-road style gloves with knuckle pads are the best for comfort and
protection.
Boots
The best footwear is a pair of sturdy over-the-calf boots with low heels.
Clothing
Always wear long sleeves and long pants to protect arms and legs. Rid-
ing pants with kneepads and a jersey with shoulder pads provide the best
protection.
Equipment Modifications
We strongly recommend that consumers do not install on a POLARIS
vehicle any equipment that may increase the speed or power of the vehi-
cle, or make any other modifications to the vehicle for these purposes.
The warranty on your POLARIS vehicle 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.
The addition of certain accessories, including (but not limited to) mow-
ers, blades, tires, sprayers, or large racks, may change the handling char-
acteristics of the vehicle. Use only POLARIS-approved accessories, and
familiarize yourself with their function and effect on the vehicle.
