Improper Use of Off-Highway Vehicle Can Cause Severe Injury or Death
Read Owner’s Manual
Read Tips Guide for the Recreational Off-Highway Vehicle Driver Follow All Instruction and Warnings
Be Prepared
Drive Responsibly
If you think or feel the vehicle may tip or roll,
reduce your risk to injury: Pay Attention and Plan Ahead
Do not allow careless or reckless driving.
Do your part to prevent injuries: Req
uire Proper Use of Your Vehicle
Rollovers have caused
severe injuries and death,
even on flat, open areas.
Stay completely inside the vehicle.
Passenger must be able to reach the handhold while
keeping feet flat on floor and sitting upright with
back against seat.
Driver must be able to comfortably reach all controls
while sitting upright with back against seat.
Wear an approved helmet, eye protection and protective gear.
Fasten seat belts.

Do not allow anyone to ride in the cargo bed.
Avoid side hilling (riding across slopes).
Plan for hills, rough terrain, ruts, and other changes
in traction and terrain. Avoid paved surfaces.
Avoid hard acceleration when turning, even from a stop.
Slow down before entering a turn.
Avoid abrupt maneuvers, sideways sliding, skidding,
or fishtailing, and never do donuts.
Avoid loss of control and rollovers: Do not put any part of your body outside of
the vehicle for any reason.
Keep a firm grip on the steering wheel
or handhold and brace yourself.

Do not exceed seating capacity: 1 passenger.
Do not allow operation on public roads
(unless designated for off-highway vehicle access)
— collisions with cars and trucks can occur.
Do not let people drive or ride
after using alcohol or drugs.
Make sure operators are 16 or older
with valid driver’s license.

• Do not drive or ride as passenger after using drugs or alcohol.
Prepare your vehicle
Perform the pre-operation checks each time you use the vehicle to make sure it is in safe oper-
ating condition. Failure to inspect or maintain the vehicle properly increases the possibility of an
accident or equipment damage. See page 5-1 for a list of pre-operation checks.
Prepare your load or trailer
Carrying loads, towing a trailer, or pulling object s can affect handling, stability, and cause the risk
of overturns or other accidents.
 Read Chapter 6 before loading, towing, or pulling objects.
 Do not overload the vehicle or trailer. Refer to label in cargo bed for cargo bed load limit. Refer
to label next to hitch for tongue weight and trailer load limits.
 Keep weight in the cargo bed centered side to side, and as low and as far forward as possible.
 Secure cargo so that it will not shift – a loose load could change handling unexpectedly or be
thrown forward and strike occupants.
While using your Yamaha Wolverine
 Keep your body completely inside the vehicle at all times. Keep both hands on the steering
wheel. Be sure the passenger is seated, belted, and holding onto the passenger handhold.
Close doors before driving. Any part of your body (arms, legs, and head) outside the vehicle
can be struck by objects your vehicle is passing or crushed by the vehicle cage/frame in a roll-
over accident.
 Watch for branches, brush, or other hazards that could enter the vehicle.

Abrupt maneuvers or aggressive driving, even on flat, open areas, can cause loss of control,
including rollovers. The Wolverine has higher ground clearance and other features to handle
rugged terrain, and, as a result, can overturn in situations where some other vehicles may not.
 Avoid rollovers:
• Use care when turning:
• Turning the steering wheel too far or too fast can result in a rollover.
• Avoid sideways sliding, skidding, or fishtail ing (rear-wheel sliding), and never do donuts.
• Slow down before entering a turn and avoid hard braking in a turn.
• When making tight turns from a stop or at sl ow speeds, avoid sudden or hard acceleration.
• Drive straight up and down inclines, not across them. If crossing a hill is unavoidable, drive
slowly and turn downhill immediately if you feel the vehicle may tip.
• Avoid paved surfaces. Turn gradually and go slowly if you must drive on pavement. This vehicle is designed for off-road use only.UB3D7AE0.book Page 4 Tuesday, November 7, 2017 9:38 AM

If you think or feel that the vehicle may tip or roll, keep your body completely inside the protec-
tive structure of the vehicle:
• Brace yourself by pressing your feet firmly on the floorboard and keep a firm grip on the
steering wheel or passenger handhold.
• Do not put your hands or feet outside of the vehicle for any reason. Your arm or leg could be
crushed.
• Do not try to stop a vehicle tipover using your arm or leg.
 Do not operate this vehicle on any public street , road, or highway, even if dirt or gravel.
 Do not operate the vehicle in fast-flowing water or water deeper than 37 cm (15 in). If you must
cross shallow, slow-moving water, choose your path carefully to avoid sharp drop-offs, large
rocks, or slippery surfaces. Operating this vehi cle through deep or fast-flowing water can lead
to loss of control or overturn. To reduce your risk of drowning or other injuries, use care when
crossing through water.
 When loaded with cargo or towing a trailer:
• Reduce speed, operate in low gear only, and allow more room to stop.
• Avoid hills and rough terrain. Use extreme cautio n when towing or carrying a load on inclines.
• Load trailer properly and use extra care when towing or pulling.
 Do not tow or pull objects from any part of the vehicle other than the trailer hitch bracket or
winch (if installed).
Avoid carbon monoxide poisoning
All engine exhaust contains carbon monoxide, a deadly gas. Breathing carbon monoxide can
cause headaches, dizziness, drowsiness, nausea, confusion, an d eventually death.UB3D7AE0.book Page 5 Tuesday, November 7, 2017 9:38 AM

Aftermarket parts, accessories, and modifications
While you may find aftermarket products similar in design and quality to genuine Yamaha Acces-
sories, recognize that some aftermarket accessori es or modifications are not suitable because
of potential safety hazards to yo u or others. Installing aftermarke t products or having other mod-
ifications performed to your Wolv erine that change any of the vehicle’s design or operation char-
acteristics can put you and others at greater risk of serious injury or death. You are responsible
for injuries related to changes in the vehicle.
Aftermarket tires and rims
The tires and rims that came with your Wolver ine were designed to match the performance ca-
pabilities and to provide the best combination of handling, braking, and comfort. Other tires,
rims, sizes, and combinations may not be appropriate. Refer to page 8-46 for tire specifications
and more information on replacing your tires.UB3D7AE0.book Page 7 Tuesday, November 7, 2017 9:38 AM
