INTRODUCTION
Preservation of the Environment
POLARIS is committed to supporting an environmental education cam-
paign. We encourage governments to adopt rigorous safety training pro-
grams that encourage protection of our environment, including wildlife
and vegetation.
Snowmobile clubs and other organizations are working together to pro-
tect our environment. Please support their efforts and operate your
snowmobile with consideration for the protection and preservation of
our environment.
Noise Level
One of the most publicized issues about snowmobiles is noise. The
Society of Automotive Engineers (SAE), the standard-setting body for
snowmobile development, recommends that snowmobiles conform to
prescribed sound levels.
POLARIS snowmobiles are engineered to conform to these SAE stan-
dards. Our muffler systems are designed to reduce noise levels and must
not be altered or removed. The sound of your snowmobile may not be
welcome to non-snowmobilers, so you have a responsibility to operate
your snowmobile with concern for others. We do our part by manufac-
turing quieter machines; we ask your help to further reduce the impact
of noise by operating your snowmobile safely and responsibly.
Air Pollution
POLARIS engineers continuously investigate ways to reduce emission
levels of two-stroke engines. We expect our efforts to lead to the reduc-
tion of potential air pollution.
In addition to our technological research, we encourage government
agencies, manufacturers, distributors, dealers, ecologists, and other
interested parties to work together to develop data on environmental
topics.

SAFETY
Operator Safety
Follow the recommended maintenance program beginning on page 62
of this manual to ensure that all critical components on the snowmobile
are thoroughly inspected by your dealer at specific mileage intervals.
Driving a snowmobile requires your full attention. DO NOT drink alcohol or use
drugs or medications before or while driving or riding as a passenger. They will
reduce your alertness and slow your reaction time.
Snowmobiles are capable of traveling at high speeds. Use extra caution to
ensure operator safety. Make sure your snowmobile is in excellent operating
condition at all times. Always check major and vital safety components before
every ride.
All POLARIS snowmobiles are designed and tested to provide safe operation
when used as directed. Failure of critical machine components may result from
operation with any modifications, especially those that increase speed or power.
DO NOT MODIFY YOUR MACHINE. The snowmobile may become
aerodynamically unstable at speeds higher than those for which it is designed.
Loss of control may occur at higher speeds. Modifications may also create a
safety hazard and lead to bodily injury.
The warranty on your entire machine is terminated if any equipment has been
added, or any modifications have been made, to increase the speed or power of
the snowmobile.
WARNING

SAFETY
Operator Safety
Stay Clear of Track
Your snowmobile is propelled by a revolving track that must be partially
exposed for proper operation.
WARNING! Serious injuries may result if hands, feet, or clothing become
entangled in the track. Be alert when riding, and remain properly seated to stay
clear of the track. Never hold the snowmobile up or stand behind it while
warming up the track. A loose track or flying debris could cause serious injury or
death. We recommend having your dealer perform all track service and
alignment procedures.
Stay Clear of Engine
Never attempt adjustments with the engine running. Turn off the igni-
tion, raise the hood, make the adjustment, secure shields and guards,
secure the hood, and then restart the engine to check its operation.
WARNING! Serious injury can occur if fingers or clothing contact the moving
parts of an engine. Always stop the engine before attempting adjustments.
Riding Position
Operating a snowmobile requires skill and balance for proper control.
Rider positions may vary with experience and the features available on
some snowmobiles, but under many conditions, the proper position is to
be seated with both feet on the running boards and both hands on the
handlebar grips for proper throttle, brake and steering control.
WARNING! Improper riding position may reduce control and could result in
serious injury or death. Always ride in a position that allows for control of your
vehicle.

Riding Apparel
Be prepared, be warm and be com-
fortable when riding. Be aware of the
weather forecast, especially the wind-
chill, and dress accordingly. See the
chart on page 20.
WARNING! Avoid wearing loose clothing
or long scarves, which can become
entangled in moving parts and cause
serious injury.
Helmet
Wearing a helmet can prevent a
severe head injury. Whenever riding a
POLARIS vehicle, always wear a helmet that meets or exceeds estab-
lished safety standards.
Approved helmets in the USA and Canada bear a U.S. Department of
Transportation (DOT) label.
Approved helmets in Europe, Asia and Oceania
bear the ECE 22.05 label. The ECE mark consists
of a circle surrounding the letter E, followed by the
distinguishing number of the country which has
granted approval. The approval number and serial
number will also be displayed on the label.
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.

Survival Preparation
For your safety, always ride in a group of other snowmobilers. Always
tell someone where you're going and how long you expect to be gone. If
it isn't possible to ride with others, and you must travel into remote
areas, always carry survival equipment that's appropriate to the condi-
tions you may encounter. Such equipment may include, but is not lim-
ited to: extra clothing, a sleeping bag, a flashlight, food and water, a
signaling mirror, a means of building a fire, and a two-way radio or cel-
lular telephone.
For added protection, carry the following items on your snowmobile at
all times:
Disabled Operators
Safe operation of this rider-active vehicle requires good judgement and
physical skills. Operators with cognitive or physical disabilities have an
increased risk of loss of control, which could result in serious injury or
death.
Cargo Overload
Too much weight on the rear of the machine may reduce your ability to
steer. If equipped, do not exceed carrier and rack weight limits, and do
not allow a passenger to sit on the cargo carrier.

Rider Capacity
Driving 1-Up - Some POLARIS snowmobiles are designed for a single
rider only. A decal on the console of these models indicates single rider
operation. Never carry a passenger on a single-rider snowmobile.
Driving 2-Up - Some POLARIS snowmobiles are designed for up to
two riders. A decal on the console of these models indicates that the
vehicle is designed for one operator and one passenger only.
WARNING! Control becomes more difficult with two people on board. More
space is required to make turns, and longer distances are needed for stopping.
Make sure the passenger remains seated behind the driver, facing forward, with
both feet placed firmly on the running boards. Slow down and avoid “jumping”
your snowmobile.
Snowmobiles designed for two riders should never be operated with
more than two people on board. When traveling with a passenger, it’s
the driver’s responsibility to operate the snowmobile safely.
Slow down! Control becomes more difficult with two people on board.
More space is required to make turns, and longer distances are necessary
for stopping.
Excessive Speed
WARNING! High speed driving, especially at night, could result in serious injury
or death. Always reduce speed when driving at night or in inclement weather.
Always observe all state and local laws governing snowmobile opera-
tion and speed limits. Always be alert and pay attention to the trail
ahead. If your speed is 40 MPH (64 km/h), your snowmobile is traveling
about 60 feet (18 m) per second. If you look back for only two seconds,
your snowmobile will travel about 120 feet (36 m). If your speed is 60
MPH (96 km/h), your snowmobile will travel about 180 feet (55 m) in
two seconds.
Traveling at night requires extra caution. Check headlight and taillight
to ensure proper operation, and don't over-drive your headlight beam.
Always be able to bring your machine to a stop in the distance illumi-
nated by the headlight.

SAFETY
Operator Safety
Driver Awareness
Slow down when traveling near poles,
posts, or other obstacles. Be especially
alert if you're snowmobiling after dark.
Always be on the alert for wire fences.
Single strands are especially dangerous,
since there may be a great distance
between posts. Guy wires on utility poles
are also difficult to distinguish.
Make sure the way is clear before crossing
railroads and other roads and highways.
The noise of your machine will drown out
the sound of approaching vehicles. Look
ahead, behind, and to both sides before
turning or crossing railroad tracks or high-
ways. Steep embankments may also hide
your view. Always leave yourself a way
out.
Variances in snow depth and/or water currents may result in uneven ice
thickness. Always check with local residents or authorities for general
information on conditions when traveling on lakes and streams that are
strange to you. Before riding your snowmobile on a frozen body of
water, be sure the ice is thick enough to support the snowmobile and its
operator, as well as the force created by a moving vehicle. You may
drown if you and the snowmobile break through the ice.
When teaching inexperienced operators to ride, set up a predetermined
course for practice. Make sure they know how to drive and control the
snowmobile before allowing them to make longer trips. Teach them
proper snowmobile courtesy, and enroll them in driver's training and
safety courses sponsored by local or state organizations.

Avalanches
Snowmobilers should always be properly
trained and equipped before traveling in
mountainous terrain:
• Take an avalanche class
• Travel with experienced people
• Travel on designated trails
• Make sure each person is equipped
with a shovel, probe and avalanche
beacon.
You don't have to be snowmobiling on a slope for an avalanche to occur.
Be aware that all of the snow is connected. You may be riding on a flat
slope or snow covered road, but if the snowpack above is unstable
enough you can trigger an avalanche on a steeper slope above you.
Always be aware of snow conditions above you as you travel in moun-
tainous terrain.
Before riding in mountainous terrain, call or log on to your local ava-
lanche advisory to get current weather and snow stability information.
For more information about avalanche training and avalanche condi-
tions, contact local law enforcement in your area, or visit either the
American Avalanche Association online at www.americanavalancheas-
sociation.org or the U.S. Forest Service National Avalanche Center at
www.avalanche.org.

Ice and Snow Build-up
WARNING! Ice and snow build-up may interfere with the steering of your
machine, resulting in serious injury or death. Keep the underhood area free of
snow and ice.
Before driving, manually turn the skis to the left and right to be sure ice
and snow are not interfering with full left and right steering. If difficulty
is encountered, remove ice and snow build-up that may be obstructing
the steering linkage.
Driving on Slippery Surfaces
WARNING! Never attempt an abrupt change of direction when operating on
slippery surfaces. Proceed slowly and use extra caution. Driving on ice or hard-
packed snow reduces steering and braking control, which may result in loss of
control and serious injury or death. Slow down and use extra caution when
operating on slippery surfaces.

15
SAFETY
Operator Safety
Driving Downhill
When riding downhill, shift your weight to the rear of the machine and
reduce your speed to a minimum. Apply just enough throttle to keep the
clutch engaged, allowing the engine's compression to help slow the
machine and keep it from rolling freely downhill.
WARNING! When driving on long downhill stretches, pump the brakes. Riding
the brakes may cause the brake system to overheat, which may result in brake
failure. Excessive or repetitive use of the brakes for high speed stops will also
cause an overheated brake system. This condition may lead to a sudden loss of
brakes and/or fire and may result in serious injury or death.

SAFETY
Operator Safety
Driving in Hilly Terrain
WARNING! Climbing a hill or crossing the face of a slope may result in loss of
balance and machine roll-over, causing serious injury or death. Use caution and
good judgement when driving in hilly terrain.
Use extra caution when operating in hilly terrain. If climbing a hill is
unavoidable, keep your weight low and forward. If you must cross the
face of a slope, keep your weight on the uphill side of the machine to
maintain proper balance and avoid possible roll-over.
Slow down when reaching the crest of a hill. Be prepared to react to
obstacles, sharp drops or other people or vehicles that may be on the
other side of the hill.
If you're unable to continue up a hill, turn the machine downhill before
it loses momentum. If this isn't possible, spin the track just enough to
dig in to prevent it from rolling back down the hill. Stop the engine and
set the parking brake (if equipped). Keeping away from the downhill
side of the machine, pull the rear of the snowmobile around and point
the front end and skis downhill. Remount the machine, restart the
engine, release the parking brake, and descend the hill carefully.
