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

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 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 symp-
toms of carbon monoxide poisoning, leave the area immediately, get fresh air, and SEEK MED-
ICAL TREATMENT.
 Do not run engine indoors. Even if you try to ventilate engine exhaust with fans or open win-
dows and doors, carbon monoxide can rapidly reach dangerous levels.
 Do not run engine in poorly ventilated or part ially enclosed areas such as barns, garages, or
carports.
 Do not run engine outdoors where engine exhaus t can be drawn into a building through open-
ings such as windows and doors.
Genuine Yamaha Accessories
Choosing accessories for your Wolverine is an important decision. Genuine Yamaha Accesso-
ries, which are available only from a Yamaha dealer, have been designed, tested, and approved
by Yamaha for use on your Wolverine.
Many companies with no connection to Yamaha manufacture parts and accessories or offer oth-
er modifications for Yamaha vehicl es. 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.UB3D7AE0.book Page 6 Tuesday, November 7, 2017 9:38 AM
