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 transmission into
reverse so you can use engine braking to
slow your descent. Release the brake, andthen begin to coast down the hill. Use engine
braking as much as possible, gently applying
the brakes when necessary.
Downhill
Check the terrain carefully before going
downhill. When possible, choose a path that
lets you drive your vehicle straight downhill.
Choose your path carefully and drive slowly
enough to be able to react to obstacles that
you encounter.
For more traction and control, before going
down steeper and/or rougher slopes, shift
into low gear and select “4WD” or “DIFF
LOCK”. Engine braking will help you go
downhill slowly. Go as slowly as possible. If
you begin to go too fast, apply the brakes
gently. Avoid hard application of the brakes,
which could cause the vehicle to slide.UB0F7AE0.book Page 19 Monday, November 6, 2017 2:30 PM

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.NOTICEECB02950After 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. 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 theUB0F7AE0.book Page 21 Monday, November 6, 2017 2:30 PM

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.If there is any question about your ability to
maneuver safely over the obstacle, you
should turn around if the ground is flat and
you have the room or back up until you find a
less difficult path.UB0F7AE0.book Page 22 Monday, November 6, 2017 2:30 PM

EBU32005PERIODIC MAINTENANCE AND ADJUSTMENTEBU32010Periodic inspection, adjustment, and lubrica-
tion will keep your vehicle in the safest and
most efficient condition possible. Safety is an
obligation of the vehicle owner/operator. The
most important points of vehicle inspection,
adjustment, and lubrication are explained on
the following pages.
WARNING
EWB01842Failure to properly maintain the vehicle or
performing maintenance activities incor-
rectly may increase your risk of injury or
death during service or while using the ve-
hicle. If you are not familiar with vehicle
service, have a Yamaha dealer perform the
service.
WARNING
EWB02563Turn off the engine when performing main-
tenance unless otherwise specified.
A running engine has moving parts that
can catch on body parts or clothing and
electrical parts that can cause shocks or
fires.
Running the engine while servicing can
lead to eye injury, burns, fire, or carbon
monoxide poisoning - possibly leading
to death. See page 2-6 for more informa-
tion about carbon monoxide.
WARNING
EWB02691Brake discs, calipers, drums, and linings
can become very hot during use. To avoid
possible burns, let brake components cool
before touching them.

use, resulting in improper fuel/air supply or
engine noise. To preven t this, the valve clear-
ance must be adjusted regularly. This adjust-
ment however, should be left to a
professional Yamaha service technician.EBU32470BrakesReplacement of brake components requires
professional knowledge. Brake service
should be performed by a Yamaha dealer.
WARNING
EWB02572Operating with improperly serviced or ad-
justed brakes could lead to a loss in brak-
ing ability and an accident. EBU35150Checking the front and rear brake padsCheck each brake pad for damage and mea-
sure the lining thickness. If a brake pad is
damaged or if the lining thickness is less than
1.0 mm (0.04 in), have a Yamaha dealer re-
place the brake pads as a set.
The wheels need to be removed to check the
brake pads. (See pages 8-55, 8-57 for wheel
removal and installation procedures.)

EBU32490Checking the parking brake padsEach brake pad is provided with a wear indi-
cator groove, which allows you to check the
brake pad wear without having to disassem-
ble the brake. If a brake pad has worn to the
point that the wear indicator groove has al-
most disappeared, have a Yamaha dealer re-
place the brake pads as a set.
EBU36610Checking the brake and YCC-S clutch
fluid levelsBefore starting off, check that the brake and
YCC-S clutch fluids are above the minimum
level marks. Replenish the brake and YCC-S
clutch fluids if necessary.
