slow your descent. Release the brake and be-
gin 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.U2MB7BE0.book Page 19 Thursday, March 3, 2016 11:46 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 your brakes. If
necessary, apply the brakes several times to
let friction dry out the linings.
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.

4. Install the gasket, and then insert the tail-pipe into the muffler and align the bolt
holes.
5. Install the bolts and tighten them to the
specified torque.
EBU32460Valve clearanceThe correct valve clearance changes with
use, resulting in improper fuel/air supply or
engine noise. To prevent 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.

As the brake pads wear, it is normal for the
brake fluid level to gradually go down. A low
brake fluid level may indicate worn brake
pads and/or brake system leakage; therefore,
be sure to check the brake pads for wear and
the brake system for leakage. If the brake fluid
level goes down suddenly, have a Yamaha
dealer check and repair the vehicle before
any further operation.EBU32520Brake fluid replacementComplete fluid replacement should be done
only by trained Yamaha service personnel.
Have a Yamaha dealer replace the following
components during pe riodic maintenance or
when they are damaged or leaking.
 Replace the oil seals every two years.
 Replace the brake hoses every four years.
EBU32530Checking the brake pedalHave a Yamaha dealer check the brakes at
the intervals specified in the periodic mainte-
nance and lubrication chart. There should be
no free play in the brake pedal. The brakes
should operate smoothly and there should be
no brake drag. If the brakes feel soft or
spongy, this could indicate air in the brake
system. Have a Yamaha dealer check the
brake system if necessary.1. Brake pedal
2. No brake pedal free play

CLEANING AND STORAGE
EBU33681CleaningFrequent, thorough cleaning of your vehicle
will not only enhance its appearance but will
improve its general performance and extend
the useful life of many components.1. Before cleaning the vehicle: a. Block off the end of the exhaust pipeto prevent water entry. A plastic bag
and strong rubber band may be used.
b. Make sure the spark plug and all filler caps are properly installed.
2. If the engine case is excessively greasy, apply degreaser with a paint brush. Do
not apply degreaser to the wheel axles.
3. Rinse the dirt and degreaser off with a garden hose. Use only enough pressure
to do the job. WARNING! Test the
brakes after washing. Apply the
brakes several times at slow speeds to
let friction dry the brakes. Wet brakes may have reduced stopping ability, in-
creasing the chance of an accident.
[EWB03471]

NOTICE: Excessive water pres-
sure may cause water seepage and
deterioration of wheel bearings,
brakes, transmission seals and electri-
cal devices. Many expensive repair
bills have resulted from improper high-
pressure detergent applications such
as those available in coin-operated car
washers.

TIPThe tailgate can be removed to make it easier
to clean the cargo bed. To separate the tail-
gate from the cargo bed, unhook the latches,
and then pull up the tailgate. (See page 4-21
for tailgate removal and installation proce-
dures.)
