EBU31730Front and rear brakesBrake pedal
Check that there is no free play in the brake
pedal. If there is free play, have a Yamaha
dealer check the brake system. (See page
8-36.)
 Check the operation of the brake pedal. It
should move smoothly and there should be
a firm feeling when the brakes are applied.
If not, have the vehicle inspected by a
Yamaha dealer.
Brake fluid level
Check the brake fluid level. Add fluid if neces-
sary. (See page 8-34.) Brake fluid leakage
Check to see if any brake fluid is leaking out
of the pipe joints or the brake fluid reservoir.
Apply the brakes firmly for one minute. If there
is any leakage, have the vehicle inspected by
a Yamaha dealer.
Brake operation
Check the operation of the brakes at the start
of every ride. Test the brakes at slow speed
after starting out to make sure they are work-
ing properly. If the brakes do not provide
proper braking performance, inspect the
brake system. (See page 8-33.)
EBU33200FuelMake sure there is sufficient fuel in the tank.
Specified brake fluid: DOT 4

Practice for new Yamaha Viking users
You should become familiar with the perfor-
mance characteristics of the vehicle in a lar-
ge, flat area that is free of obstacles and other
vehicles. Practice controlling the accelerator
pedal, brakes, steering, and drive select lever.
Drive at slow speeds with gradual accelera-
tion and turning. Practice smooth throttle ap-
plication. Practice slowing down before
turning. Practice maintaining a steady throttle
through the turn. Avoid higher speeds until
you are thoroughly familiar with the operation
of your vehicle. Remember, driving aggres-
sively or making abrupt maneuvers even on
flat, open areas can cause side rollovers. Become familiar with the way the vehicle feels
in low and high ranges, first in two-wheel
drive “2WD” and then in four-wheel drive
“4WD” and four-wheel drive with the differen-
tial locked “DIFF LOCK”. Steering may take
more effort in four-wheel drive with the differ-
ential locked “DIFF LOCK”. Also practice
driving in reverse.
Take the time to learn basic operation of the
vehicle before attempting more difficult ma-
neuvers.UB427BE0.book Page 13 Friday, February 5, 2016 2:14 PM

Avoid higher speeds and sudden or hard ac-
celeration until you are thoroughly familiar
with the operation of your vehicle. Avoid sud-
den or hard acceleration in any turn.
Braking
When slowing down or stopping, take your
foot off the accelerator pedal and press the
brake pedal smoothly. Improper use of the
brakes can cause the tires to lose traction, re-
ducing control of the vehicle and increasing
the possibility of an accident.
Braking ability is affected by type of terrain. In
most cases, gradual application of the brakes
is more effective than abrupt braking, partic-
ularly on loose surfaces, such as gravel. Al-
ways allow for greater braking distance on
rough, loose, or slippery surfaces.
Engine braking
Engine compression braking is designed to
assist you when operating your Viking off-
road. With this feature, the engine helps slow the vehicle down after you take your foot off
the accelerator. Engine braking is more no-
ticeable in four-wheel drive. Application of ve-
hicle brakes provides additional stopping
power.
Leaving the vehicle
Do not get out of the vehicle while the engine
is running and the drive select lever is in any
gear. There is a risk of injury because:

Children or others may accidentally press
the accelerator pedal.
 Objects tossed into the vehicle may strike
the accelerator pedal.
 The parking brake may not keep the vehicle
from accelerating.
Unwanted vehicle movement can cause seri-
ous injury or death, and it may be dangerous
to try to stop the vehicle.UB427BE0.book Page 15 Friday, February 5, 2016 2:14 PM

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 toslow 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.UB427BE0.book Page 18 Friday, February 5, 2016 2:14 PM

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. If you feel the vehicle begin to slide sideways
or the back wheels slide during a turn, steer
into the direction of the slide if possible, to re-
gain directional 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 passengers.
Never hold onto the cage/frame. The passen-
gers 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 theUB427BE0.book Page 20 Friday, February 5, 2016 2:14 PM

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.
EBU32480Checking the front and rear brake padsEach brake pad is provided with wear indica-
tor grooves, which allow you to check the
brake pad wear without having to disassem-
ble the brake. To check the brake pad wear,
check the wear indicator grooves. If a brake
pad has worn to the point that the wear indi-
cator grooves have almost disappeared, have
a Yamaha dealer replace the brake pads as a
set.
The wheels need to be removed to check the
brake pads. (See pages 8-40, 8-42 for wheel
removal and installation procedures.)

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 the cause before further riding.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.
EBU32540Parking brake lever free play adjust-
mentPeriodically check the parking brake lever
free play and adjust it if necessary.1. Brake pedal
