Portable fuel containers
If you carry a portable fuel container in the
bed of your Yamaha Viking, be sure to secure
it with the cap tightened before driving the ve-
hicle.
Always place a portable fuel container on the
ground before filling it. Before removing the
container cap, touch the container with the
fuel dispenser nozzle. Keep fuel dispenser
nozzle in contact with container inlet when fill-
ing. WARNING! Never refill a fuel container
in the bed of any vehicle. Fire may result
from a build-up of static electricity. The discharge of this build-up while refueling
can cause a spark and ignite the gasoline.

EBU31750Engine oilMake sure the engine oil is at the specified
level. Add oil as necessary. (See page 8-11.)NOTICEECB00301
In order to prevent clutch slippage (since
the engine oil also lubricates the clutch),
do not mix any chemical additives. Do
not use oils with a diesel specification of
“CD” or oils of a higher quality than
specified. In addition, do not use oils la-
beled “ENERGY CONSERVING II” or
higher.
Make sure that no foreign material en-
ters the crankcase.
Recommended fuel:
Regular unleaded gasoline only
For Europe: Regular unleaded gasoline only
with a research octane number of 95 or
higher
Fuel tank capacity: 36.7 L (9.69 US gal, 8.07 Imp.gal)
Recommended engine oil type and quantity:See page 10-1.

EBU31760CoolantCheck the coolant level in the coolant reser-
voir when the engine is cold (the coolant level
will vary with engine temperature).
The coolant level is satisfactory if it is be-
tween the minimum and maximum level
marks on the coolant reservoir. If the coolant
level is at or below the minimum level mark,
add additional coolant to bring the level up to
maximum level mark. If coolant is not avail-
able, add distilled water. Change the coolant
every two years. (See page 8-20.)NOTICEECB02120Hard water or salt water is harmful to the
engine. You may use soft water if you can-
not get distilled water.
EBU31770Final gear oilMake sure the final gear oil is at the specified
level. Add oil as necessary. (See page 8-16
for details.)
If desired, an SAE 80W-90 hypoid gear oil
may be used for all conditions.TIPGL-4 is a quality and additive rating; GL-5 or
GL-6 rated hypoid gear oils may also be used. EBU31780Differential gear oilMake sure the differential gear oil is at the
specified level. Add oil as necessary. (See
page 8-18 for details.)
Coolant reservoir capacity (up to the maxi-
mum level mark):0.28 L (0.30 US qt, 0.25 Imp.qt)
Recommended oil:SAE 80 API GL-4 Hypoid gear oil

EBU31790Accelerator pedalCheck to see that the accelerator pedal oper-
ates correctly. It must operate smoothly and
spring back to the idle position fully when re-
leased. Have a Yamaha dealer repair as nec-
essary for proper operation.EBU31800Seat beltsMake sure that the seat belts are not frayed,
torn, stretched, or damaged. The seat belts
must move smoothly when pulled out and re-
tract on its own when released. The seat belts
must also lock up when quickly pulled out.
The latch plate should click securely into the
buckle and release when the release button is
pushed firmly. Wash off any dirt or mud that
could affect operation. Have a Yamaha dealer
repair as necessary for proper operation.
A crash can damage the restraint systems in
your vehicle. A damaged restraint system
may not properly protect the person using it,
resulting in serious injury or death in a crash.To help make sure your restraint systems are
working properly after a crash, have them in-
spected and any necessary replacements
made as soon as possible.
EBU31810Passenger handholdCheck that the handhold bar and its supports
are in good condition. Confirm that the lock-
ing pins are securely fastened, and then push
and pull on the handhold to make sure that it
is not loose.EBU31820SteeringPark on level ground. Turn the steering wheel
right and left. Check for excessive free play,
abnormal noises, or a rough feeling. Have a
Yamaha dealer repair as necessary for proper operation.

EBU31830Fittings and fastenersAlways check the tightness of chassis fittings
and fasteners before a ride. Take the vehicle
to a Yamaha dealer or refer to the Service
Manual for correct tightening torque.EBU31840Instruments, lights and switchesCheck that all instruments, lights and switch-
es are working properly. Correct if necessary.EBU31850Control cablesWhen riding in cold weather, always make
sure all control cables work smoothly before
you begin riding. WARNING! Control cables
can freeze in cold weather and you could
be unable to control the vehicle.

TiresCheck tire pressure regularly to make sure it
is at the recommended specifications. Also
check for wear and damage. Tire pressure
Use the tire pressure gauge to check and ad-
just tire pressures when the tires are cold. Tire
pressures must be equal on both sides.
WARNING! Operation of this vehicle with
improper tire pressure may cause severe
injury or death from loss of control or roll-
over. Tire pressure below the minimum
specified could also cause the tire to dis-
lodge from the rim under severe riding
conditions.
[EWB02542]
Set tire pressures to the following specifica-
tions:

The tire pressure gauge is included as stan-
dard equipment. Make two measurements of
the tire pressure and use the second reading.
Dust or dirt in the gauge could cause the first
reading to be incorrect.

OPERATION
EBU31880Read the Owner’s Manual carefully to be-
come familiar with all controls. If there is a
control or function you do not understand,
ask your Yamaha dealer.
WARNING
EWB03290Failure to familiarize yourself with the con-
trols can lead to loss of control, which
could cause an accident or injury. EBU31890Engine break-inThere is never a more important period in the
life of your vehicle than the period between 0
and 20 hours.
For this reason, we ask that you read the fol-
lowing material carefully. Because the engine
is brand new, you must not put an excessive
load on it for the first several hours of opera-
tion. During the first 20 hours, the variousparts in the engine wear and polish them-
selves to achieve the correct operating clear-
ances.
During this period, prolonged full-throttle op-
eration or any condition that might result in
excessive engine heating must be avoided.
However, momentary (2–3 seconds maxi-
mum) full-throttle operation under load does
not harm the engine.
Each full-throttle acceleration sequence
should be followed with a substantial rest pe-
riod for the engine, by cruising at lower r/min
so the engine can rid itself of the temporary
build-up of heat. If any abnormality is noticed
during this period, consult a Yamaha dealer.
0–10 hours:
Avoid continuous operation above 1/2-throt-
tle. Allow a cooling-off period of 5 to 10 min-
utes after every hour of operation. Vary the
speed of the vehicle from time to time. Do not
operate it at one set throttle position.UB427AE0.book Page 1 Monday, May 18, 2015 9:17 AM

10–20 hours:
Avoid prolonged operation above three-quar-
ter throttle.
After break-in:
The vehicle may now be operated normally.EBU33080Starting the engine1. Turn the key to “ ” (on).NOTICEECB02290The coolant temperature warning light and
engine trouble warning light should come
on, then go off.
The EPS warning light should come on,
then go off when the engine is started.
If a warning light does not go off, see page
4-2 for the corresponding warning light
circuit check. 2. Apply the brake pedal.
3. Shift the drive select lever into the neutral position.
When the drive select lever is in the
neutral position, the neutral indicator
light should come on. If the neutral indi-
cator light does not come on, ask a
Yamaha dealer to inspect the electric
circuit.
The engine can be started in any gear if
the brake pedal is applied. However, it
is recommended to shift into neutral
before starting the engine.
4. With your foot off the accelerator pedal,
start the engine by turning the key to “ ”
(start).
If the engine fails to start, release the key, and
then try starting it again. Wait a few seconds
before the next attempt. Each attempt should
be as short as possible, to preserve battery
energy. NOTICE: Do not crank the engine
more than 5 seconds on each attempt, or
starter damage could occur. Wait at least
5 seconds between each operation of the
electric starter to let it cool.
