Loading
The total weight of operator, passenger, ac-
cessories, cargo, trailer tongue weight, and
the vehicle itself must not exceed 975 kg
(2150 lb). Vehicle loading can affect handling.
(See page 6-7.)EBU33551Operation on different surfaces and
terrainsGo slowly and proceed with caution when op-
erating on an unfamiliar surface or terrain.
This vehicle may handle differently in certain
types of terrains or on certain surfaces. You
may come upon hidden rocks, bumps, or
holes without enough time to react. To avoid
loss of control or rollover, always be alert to
changing surfaces or terrain when operating
the vehicle. Your Yamaha Wolverine has higher ground
clearance and other features to handle rug-
ged terrain, and as a result, can overturn in
situations where some vehicles may not.
Abrupt maneuvers or aggressive driving can
cause loss of control, including rollovers –
even on flat, open areas. These rollovers can
result in crushed limbs and other serious inju-
ries or death to drivers or passengers.
Hills
Choose carefully which hills you attempt to
climb or descend. Avoid hills with slippery
surfaces or those where you will not be ableUB3D7AE0.book Page 17 Tuesday, November 7, 2017 9:38 AM

to see far enough ahead of you. Use common
sense and remember that some hills are too
steep for you to climb or descend. Use proper
driving techniques to avoid rearward, for-
ward, or sideways rollovers on hills and
slopes.
Drive straight up and down inclines, not
across them. If crossing a hill is unavoidable,
drive slowly. Turn downhill immediately if you
feel the vehicle may tip.
If you think or feel the vehicle may tip or
roll:
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.
Uphill
Do not attempt to climb hills until you have
mastered basic maneuv ers on flat ground.
Drive straight up hills, and avoid crossing the side of a hill, which increases your risk of roll-
over. Practice first on gentle slopes before at-
tempting steeper hills. Always check the
terrain carefully before attempting any hill.
To climb a hill, you need traction, momentum,
and steady throttle. For more traction and
control for climbing steeper and/or rougher
slopes, shift into low gear and select “4WD”
or “DIFF LOCK”. Travel fast enough to main-
tain momentum, but not so fast that you can-
not react to changes in the terrain as you
climb.
Slow down when you reach the crest of the
hill if you cannot see clearly what is on the
other side – there could be another person, an
obstacle, or a sharp drop-off.
If you start to lose traction or momentum
when climbing, and decide you will be unable
to continue, use the brakes to stop. Do not at-
tempt to turn the vehicle around. With your
foot on the brake pedal, look behind you and
plan your descent. Shift the drive select lever
into reverse so you can use engine braking toUB3D7AE0.book Page 18 Tuesday, November 7, 2017 9:38 AM

Pavement
This vehicle is designed for off-road use only.
Avoid paved surfaces. Turn gradually and go
slowly if you must drive on pavement.
Water
If you must cross shallow, slow-moving water
up to the depth of the vehicle’s floorboard,
choose your path carefully to avoid sharp
drop-offs, large rocks, or slippery surfaces
that could cause the vehicle to overturn. Nev-
er operate through water deeper than 37 cm
(15 in) or fast-flowing water. Choose a path
where both your entrance into and exit point
from the water is a gradual incline. Determine
the water depth and currents before crossing.
Operating this vehicle 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.Wet brakes may have reduced effectiveness.
After leaving the water, test the brakes. If nec-
essary, apply the brakes several times to let
friction dry them out.
NOTICEECB02170After driving your vehicle in water, be sure
to drain the trapped water by removing the
check hoses at the bottom of the air filter
case and air duct and the V-belt case drain
plug. Wash the vehicle in fresh water if it
has been operated in salt water or muddy
conditions. Loose terrain/slippery terrain
When driving on slippery terrain, including
wet, muddy, or icy conditions, as well as
loose gravel, be aware that you could begin
skidding or sliding. To avoid loss of control,
slow down and put the vehicle in four-wheel
drive before driving on a slippery surface and
plan your path to avoid making abrupt ma-
neuvers.

If you feel the vehicle begin to slide sideways
or fishtail (rear-wheel sliding), steer into the di-
rection of the slide if possible, to regain direc-
tional control. For example, if you feel the
back of the vehicle start to slide to your right,
steer to the right.
Brush or wooded areas
When operating in areas with brush or trees,
watch carefully on both sides and above the
vehicle for obstacles such as branches that
the vehicle might hit, causing an accident.
Watch for brush that might enter the vehicle
as you pass and strike you or the passenger.
Never hold onto the cage/frame. The passen-
ger should always hold onto the passenger
handhold with both hands.
The muffler and other engine parts become
extremely hot during operation and remain
hot after the engine has stopped. To reduce
the risk of fire during operation or after leaving
the vehicle, do not let brush, grass and other
materials collect under the vehicle, near the muffler or exhaust pipe, or next to other hot
parts. Check under the vehicle after operating
in areas where combustible materials may
have collected. Do not idle or park the vehicle
in long dry grass or other dry ground cover.
Encountering obstacles
If you cannot go around an obstacle, such as
a fallen tree or a ditch, stop the vehicle where
it is safe to do so. Set the parking brake and
get out to inspect the area thoroughly. Look
from both your approach side and exit side. If
you believe you can continue safely, choose
the path that will allow you to get over the ob-
stacle and at as close to a right angle as pos-
sible to minimize vehicle tipping. Go only fast
enough to maintain your momentum but still
give yourself plenty of time to react to chang-
es in conditions.UB3D7AE0.book Page 21 Tuesday, November 7, 2017 9:38 AM
