If you think or feel that the vehicle may tip or roll, keep your body completely inside the protec-
tive structure of the vehicle:
• Brace yourself by pressing your feet firmly on the floorboard and keep a firm grip on the
steering wheel or passenger handhold.
• Do not put your hands or feet outside of the vehicle for any reason. Your arm or leg could be
crushed.
• Do not try to stop a vehicle tipover using your arm or leg.
 Do not operate this vehicle on any public street , road, or highway, even if dirt or gravel.
 Do not operate the vehicle in fast-flowing water or water deeper than 37 cm (15 in). If you must
cross shallow, slow-moving water, choose your path carefully to avoid sharp drop-offs, large
rocks, or slippery surfaces. Operating this vehi cle 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.
 When loaded with cargo or towing a trailer:
• Reduce speed, operate in low gear only, and allow more room to stop.
• Avoid hills and rough terrain. Use extreme cautio n when towing or carrying a load on inclines.
• Load trailer properly and use extra care when towing or pulling.
 Do not tow or pull objects from any part of the vehicle other than the trailer hitch bracket or
winch (if installed).
Avoid carbon monoxide poisoning
All engine exhaust contains carbon monoxide, a deadly gas. Breathing carbon monoxide can
cause headaches, dizziness, drowsiness, nausea, confusion, an d eventually death.UB427BE0.book Page 5 Friday, February 5, 2016 2:14 PM

Carbon monoxide is a colorless, odorless, tasteless gas which may be present even if you do not
see or smell any engine exhaust. Deadly levels of carbon monoxide can collect rapidly and you
can quickly be overcome and unable to save yourself. Also, deadly levels of carbon monoxide
can linger for hours or days in enclosed or poorly-ventilated areas. If you experience any symp-
toms of carbon monoxide poisoning, leave the area immediately, get fresh air, and SEEK MED-
ICAL TREATMENT.
 Do not run engine indoors. Even if you try to ventilate engine exhaust with fans or open win-
dows and doors, carbon monoxide can rapidly reach dangerous levels.
 Do not run engine in poorly ventilated or part ially enclosed areas such as barns, garages, or
carports.
 Do not run engine outdoors where engine exhaus t can be drawn into a building through open-
ings such as windows and doors.
Genuine Yamaha Accessories
Choosing accessories for your Vi king is an important decision. Genuine Yamaha Accessories,
which are available only from a Yamaha dealer , have been designed, tested, and approved by
Yamaha for use on your Viking. Many companies with no connection to Yamaha manufacture parts and accessories or offer oth-
er modifications for Yamaha vehicl es. Yamaha is not in a position to test the products that these
aftermarket companies produce. Therefore, Yamaha can neither endorse nor recommend the
use of accessories not sold by Yamaha or modifications not specifically recommended by
Yamaha, even if sold and installed by a Yamaha dealer.UB427BE0.book Page 6 Friday, February 5, 2016 2:14 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.UB427BE0.book Page 21 Friday, February 5, 2016 2:14 PM

TIPBe sure to wipe off spilled oil on any parts af-
ter the engine and exhaust system have
cooled down. 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.
12. Start the engine, and then let it idle for
several minutes while checking it for oil
leakage. If oil is leaking, immediately turn
the engine off and check for the cause.
13. Turn the engine off, wait at least 10 minu-
tes, and then check the oil level and cor-
rect it if necessary.
14. Install the right rear panel by installing the
bolts and the quick fastener screws.
15. Lower the cargo bed.EBU36050Final gear oilCheck the oil level and change the final gear
oil at the intervals specified in the general
maintenance and lubrication chart.
Checking the final gear oil level 1. Park the vehicle on a level surface.
Recommended engine oil: See page 10-1.
Oil quantity: Without oil filter cartridge replacement:2.20 L (2.33 US qt, 1.94 Imp.qt)
With oil filter cartridge replacement: 2.30 L (2.43 US qt, 2.02 Imp.qt)

EBU32440V-belt case drain plugThe V-belt case drain plug is located under
the cargo bed. (See page 4-22 for cargo bed
lifting and lowering procedures.)
After riding in water deep enough to allow wa-
ter to enter the V-belt case, remove the drain
plug to drain any water from the case.
If water drains from the V-belt case after re-
moving the drain plug, have a Yamaha dealer
inspect the vehicle, as the water may affect
other engine parts.

WARNING
EWB03370Hot exhaust system may cause burns. To
avoid burns or fires, make sure that the en-
gine is stopped and the exhaust system is
cool before cleaning the spark arrester. Do
not start the engine while cleaning the ex-
haust system. 1. Remove the tailpipe bolts.

CLEANING AND STORAGE
EBU32731CleaningFrequent, 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.
[ECB00712]
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,
lift the left side of the tailgate and pull the tail-
gate to the left. 4. Once the majority of the dirt has been hosed off, wash all surfaces with warm
water and mild, detergent-type soap. An
old toothbrush or bottle brush is handy
for hard-to-get-at places.

4. Put the frame on stands or blocks to raiseall wheels off the ground.
5. Tie a plastic bag over the exhaust pipe outlet to prevent moisture from entering.
6. If storing in a humid or salt-air atmo-
sphere, coat all exposed metal surfaces
with a light film of oil. Do not apply oil to
any rubber parts or the seat covers.
7. Remove the battery and charge it. Store it in a dry place and recharge it once a
month. Do not store the battery in an ex-
cessively warm or cold place [less than 0
°C (30 °F) or more than 30 °C (90 °F)].
Use of fuel stabilizer eliminates the need to
drain the fuel system. Consult a Yamaha
dealer if the fuel system needs to be drained.
