then 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.If you are sliding or skidding, try to steer in the
direction the vehicle is sliding, to regain con-
trol. For example, if you feel the back of the
vehicle start to slide to your right, steer to the
right.
If you must turn on the hill to avoid an obsta-
cle, do so slowly and carefully. If the vehicle
starts to tip, immediately steer in the downhill
direction if there are no obstacles in your
path. As you regain proper balance, gradually
steer again in the direction you want to go.
Rough terrain
Operation over rough terrain should be done
with caution.

Look for and avoid obstacles that could
cause damage to the vehicle or could lead
to a rollover or accident.
 Do not drive in a way that will get the vehicle
airborne, as injury, loss of control, and
damage to the vehicle could occur.UBAS7AE0.book Page 19 Wednesday, June 19, 2019 11:51 AM

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.UBAS7AE0.book Page 21 Wednesday, June 19, 2019 11:51 AM

EBU32007PERIODIC 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 3-6 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.
