PAY ATTENTION TO YOUR SAFETY
This section presents some of the most important information and recommendations
to help you ride your UTV safely. Please take a few moments to read these pages.
This section also includes information about the location of safety labels on your
UTV.
Important safety information
Your UTV can provide many years of service and pleasure-if you take responsibility
for your own safety and understand the challenges you can meet while riding.
There is much that you can do to protect yourself when you ride. You’ll find many
helpful recommendations throughout this manual. The following are a few that we
consider most important.
Follow the age recommendation
The minimum recommended age of this UTV model is 16. Children under age 16
should never operate this vehicle.

- 2 -
Always wear a helmet
It’s a proven fact: helmets significantly reduce the number and severity of head
injuries. So always wear an approved motorcycle helmet.
Protection, sturdy boots, gloves, and other protective gear.
Ride off-road only
Your UTV is designed and manufactured for off-road use only. The tires are not
made for pavement, and the UTV does not have turn signals and other features
required for use on public roads. If you need to cross a paved or public road, get off
and walk your UTV across.
Take time to learn & practice
Even if you have ridden other UTVs, take time to become familiar with your skills and
get accustomed to the UTV is size and weight.
Because many accidents involve inexperienced or untrained riders, we urge all riders
to take
a training course approved by the UTV safety institute.
Contact an authorized UTV dealer to find out about the training courses nearest you.

- 3 -
Be alert for off-road hazards
The terrain can present a variety of challenges when you ride off-road. Continually
“read” the terrain for unexpected turns, drop-offs, rocks, ruts, and other hazards.
Always keep your speed low enough to allow time to see and react to hazards.
Ride within your limits
Pushing limits is another major cause of UTV accidents. Never ride beyond your
personal abilities or faster than conditions warrant.
Remember that alcohol, drugs, fatigue, and inattention can significantly reduce your
ability to make good judgments and ride safely.
Don’t drink and ride
Alcohol and riding don’t mix. Even one drink can reduce your ability to respond to
changing conditions, and your reaction time gets worse with every additional drink.
So don’t drink and ride, and don’t let your friends drink and ride either.

- 4 -
Keep your UTV in safe condition
It’s important to keep your UTV properly maintained and in safe riding condition.
Having a breakdown can be difficult, especially if you are stranded off-road far from
your base. To help avoid problems, inspect your UTV before every ride and perform
all recommended maintenance.
Your UTV comes with a hangtag and several labels containing important safety
information. Anyone who rides the vehicle should read and understand this
information before riding.
The labels should be considered permanent parts of the vehicle. If a label comes off
or becomes hard to read, contact your dealer for replacements.
