Safety information
ESU10183
As the vehicle’s owner, you are responsible
for the safe and proper operation of your
snowmobile. When you ride your snowmobile, you must know and use the following for
your safety. Severe injury or death may result
if you ignore any of the following.
Before you operate your snowmobile
● Read the Owner’s Manual and all labels.
Become familiar with all of the operating
controls and their function. Consult a
Yamaha dealer about any control or func-
tion you do not understand.
● Wear protective clothing. Wear an ap-
proved helmet, and a face shield or goggles. Also, wear a good quality snowmobile
suit, boots, and a pair of gloves or mittens
that will permit use of your thumbs and fingers for operation of the controls.
● Apply the parking brake before starting the
engine. Never drive the snowmobile with
the parking brake applied. This may overheat the brake disc and reduce braking ability.
While using your snowmobile
● This snowmobile was not manufactured for
use on public streets, roads, or highways.
Such use is prohibited by law, and you
could collide with another vehicle.
● This snowmobile is designed to carry the
OPERATOR ONLY. Passengers are prohibited. Carrying a passenger can cause
loss of control.
● Do not operate the snowmobile after or
while drinking alcohol or taking drugs. Your
ability to operate the snowmobile is reduced by the influence of alcohol or drugs.
Prepare your snowmobile
● Perform the pre-operation checks each
time you use the vehicle to make sure it is
in safe operating condition. Failure to inspect or maintain the vehicle properly increases the possibility of an accident or
equipment damage. See page 31 for a list
of pre-operation checks.
6
● Be careful where you ride. There may be
obstacles hidden beneath the snow. Stay
on established trails to minimize your exposure to hazards. Ride slowly and cautiously
when you ride off of established trails. Hitting a rock or stump, or running into wires
could cause an accident and injury.
● This snowmobile is not designed for use on
surfaces other than snow or ice. Use on dirt,
sand, grass, rocks, or bare pavement may
cause loss of control and may damage the
snowmobile.
● Always ride with other snowmobilers when
going on a ride. You may need help if you
run out of fuel, have an accident, or damage
your snowmobile.
Safety information
● Many surfaces such as ice and hardpacked
snow require much longer stopping distances. Be alert, plan ahead and begin decelerating early. The best braking method on
most surfaces is to release the throttle and
apply the brake gently—not suddenly.
Avoid carbon monoxide poisoning
All engine exhaust contains carbon monoxide, a deadly gas. Breathing carbon monoxide
can cause headaches, dizziness, drowsiness,
nausea, confusion, and eventually death.
Carbon monoxide is a colorless, odorless,
tasteless gas which may be present even if
you do not see or smell any engine exhaust.
Deadly levels of carbon monoxide can collect
rapidly and you can quickly be overcome and
be unable to save yourself. Also, deadly levels of carbon monoxide can linger for hours or
days in enclosed or poorly-ventilated areas. If
you experience any symptoms of carbon
monoxide poisoning, leave the area immediately, get fresh air, and SEEK MEDICAL
TREATMENT.
● Do not run the engine indoors. Even if you
try to ventilate engine exhaust with fans or
open windows and doors, carbon monoxide
can rapidly reach dangerous levels.
● Do not run the engine in poorly ventilated or
partially enclosed areas such as barns, garages, or carports.
● Do not run the engine outdoors where en-
gine exhaust can be drawn into a building
through openings such as windows and
doors.
Genuine Yamaha Accessories
Choosing accessories for your snowmobile is
an important decision. Genuine Yamaha Accessories, which are available only from a
Yamaha dealer, have been designed, tested,
and approved by Yamaha for use on your
snowmobile. Many companies with no connection to Yamaha manufacture parts and ac-
cessories or offer other modifications for
Yamaha vehicles. Yamaha is not in a position
to test the products that these aftermarket
companies produce. Therefore, Yamaha can
neither endorse nor recommend the use of
accessories not sold by Yamaha or modifications not specifically recommended by
Yamaha, even if sold and installed by a
Yamaha dealer.
Maintenance and storage
● When laying the snowmobile on its side for
maintenance, use a suitable stand to keep
it in a stable and level position.
● Do not leave the snowmobile on its left side
for an extended period of time. Fuel may
leak out from the fuel breather hose.
● Do not allow anyone to stand behind the
snowmobile when starting, inspecting, or
adjusting the snowmobile. A broken track,
track fittings, or debris thrown by the track
could be dangerous to the operator or bystanders.
● Modifications made to the snowmobile not
approved by Yamaha, or the removal of
original equipment may render your snowmobile unsafe for use, which may cause severe personal injury. Modifications may
also make the snowmobile illegal to use.
● Never store the snowmobile with fuel in the
fuel tank inside a building where ignition
sources are present such as hot water and
space heaters, an open flame, sparks,
clothes dryers, and the like. Allow the engine to cool off before storing the snowmobile in an enclosed space.

ESU10312
Throttle lever
Once the engine is running cleanly, squeezing the throttle lever will increase the engine
speed and cause engagement of the drive
train. Regulate the speed of the snowmobile
by varying the throttle position. Because the
throttle is spring-loaded, the snowmobile will
decelerate, and the engine will return to idle
when it is released.

WARNING
If the T.O.R.S. is activated, make sure that
the cause of the malfunction has been corrected and that the engine can be operated
without a problem before restarting the
engine. Continuing to operate with a malfunction could cause loss of control or
damage.
If the throttle valves or throttle cable malfunctions during operation, the T.O.R.S. will be activated when the throttle lever is released.
The T.O.R.S. is designed to override the fuel
injection and limit the engine speed to less
than the clutch engagement speed if the throttle valves fail to return to the idle position
when the throttle lever is released. (See page
84 for the clutch engagement speed.)

Fuel
EWS00071
WARNING
Gasoline and gasoline vapors are extremely flammable. To avoid fires and explosions and to reduce the risk of injury
when refueling, follow these instructions.
Make sure there is sufficient gasoline in the
tank.
1. Before refueling, turn off the engine and
be sure that nobody is on the snowmobile. Never refuel while smoking, or while
in the vicinity of sparks, open flames, or
other sources of ignition such as the pilot
lights of water heaters and clothes dryers.
2. Do not overfill the fuel tank. Stop filling
when the fuel reaches the bottom of the
filler tube. Because fuel expands when it
heats up, heat from the engine or the sun
can cause fuel to spill out of the fuel tank.
23
Control functions
1. Filler tube
2. Maximum fuel level
3. Wipe up any spilled fuel immediately.
4. Be sure the fuel tank cap is closed securely by turning it clockwise.
EWS00680
WARNING
Gasoline is poisonous and can cause injury or death. Handle gasoline with care.
Never siphon gasoline by mouth. If you
should swallow some gasoline or inhale a
lot of gasoline vapor, or get some gasoline
in your eyes, see your doctor immediately.
If gasoline spills on your skin, wash with
soap and water. If gasoline spills on your
clothing, change your clothes.
Recommended fuel:
REGULAR UNLEADED GASOLINE
ONLY
Fuel tank capacity:
35.6 L (9.41 US gal, 7.83 Imp.gal)
Your Yamaha engine has been designed to
use regular unleaded gasoline with a pump
octane number [(R+M)/2] of 86 or higher, or a
research octane number of 91 or higher.
ECS00082
NOTICE
● Oxygenated fuels (gasohol) containing
a maximum 5% of ethanol (E5) can be
used, although richer jetting may be required to prevent engine damage. Consult a Yamaha dealer. Gasohol
containing methanol is not recommended.
● Make sure that snow or ice does not en-
ter the fuel tank when refueling.
● Do not use alcohol deicers or water ab-
sorbing additives with oxygenated fuel.
● The fuel tank should be filled with the
recommended gasoline as specified.

Suspension
The suspension can be adjusted to suit rider
preference. Softer settings, for example, may
provide greater rider comfort, while harder
settings may allow more precise handling and
control over certain types of terrain or riding
conditions.
If you are not familiar with suspension adjustments, have a Yamaha dealer make these
adjustments.
