5B410002Coolant temperature warning light “ ”
If the coolant temperature reaches a specific
level, this light comes on to warn that the cool-
ant temperature is too hot. If the light comes
on during operation, stop the engine as soon
as it is safe to do so and allow the engine to
cool down for about 10 minutes.
(See page 8-58.)
The electrical circuit of the warning light can
be checked by turning the key to “ ” (on). If
the warning light does not come on initially
when the key is turned to “ ” (on), or if the
warning light remains on, have a Yamaha
dealer check the electrical circuit.
NOTICE●
The engine may overheat if the vehicle
is overloaded. If this happens, reduce
the load to specification.
●
After restarting, make sure that the
warning light is out. Continuous use
while this warning light is on may
cause damage to the engine.

5B410003Engine trouble warning light “ ”
This warning light comes on or flashes if a
problem is detected in the electrical circuit
monitoring the engine. When this occurs,
have a Yamaha dealer check the self-diagno-
sis system. (See page 4-11 for an explanation
of the self-diagnosis device.)
The electrical circuit of the warning light can
be checked by turning the key to “ ” (on). If
the warning light does not come on initially
when the key is turned to “ ” (on), or if the
warning light remains on, have a Yamaha
dealer check the electrical circuit.Electric Power Steering warning light
“EPS”
This warning light comes on when the key is
turned to “ ” (on), and then goes off once
the engine is started. If the warning light re-
mains on or comes on after the engine is
started, the EPS system may not be working
correctly. When this occurs, have a Yamaha
dealer check the EPS system.
The electrical circuit of the warning light can
be checked by turning the key to “ ” (on). If
the warning light does not come on, have a
Yamaha dealer check the electrical circuit.
TIPIf the steering load is too heavy (i.e., exces-
sive steering use when the Viking is traveling
at a slow speed), the power assist is reduced
to protect the EPS motor from overheating.

TIPThis fuel meter is equipped with a self-diagno-
sis system. If a problem is detected in an elec-
trical circuit, all the display segments and fuel
level warning indicator start flashing. If this oc-
curs, have a Yamaha dealer check the electri-
cal circuit.
Self-diagnosis device1. Error code display
2. Engine trouble warning light “ ”This model is equipped with a self-diagnosis
device for various electrical circuits.
If a problem is detected in any of those cir-
cuits, the engine trouble warning light comes
on or flashes, and the multi-function display
indicates an error code.
If the multi-function display indicates an error
code, note the code number, and then have a
Yamaha dealer check the vehicle.

1-FOR YOUR SAFETY – PRE-OPERATION CHECKS
Inspect your vehicle each time you use it to make sure the vehicle is in safe operating condition.
Always follow the inspection and maintenance procedures and schedules described in the Own-
er’s Manual.
WARNING
Failure to inspect or maintain the vehicle properly increases the possibility of an accident
or equipment damage. Do not operate the vehicle if you find any problem. If a problem
cannot be corrected by the procedures provided in this manual, have the vehicle inspect-
ed by a Yamaha dealer.Before using this vehicle, check the following points:
ITEMROUTINE PAGE
Brakes Check operation, free play, fluid level, and fluid leakage.
Fill with DOT 4 brake fluid if necessary. 5-3, 8-32, 8-36
Parking brake Check for proper operation, condition, and free play. 8-35
Fuel Check fuel level.
Fill with the recommended fuel if necessary. 5-4
Engine oil Check oil level.
Fill with oil to proper level if necessary. 5-6, 8-9
Coolant Check coolant level in reservoir.
Fill with coolant if necessary. 5-6, 8-20

EVU00410Engine oilMake sure the engine oil is at the specified
level. Add oil as necessary. (See page 8-9.)NOTICE●
In order to prevent clutch slippage
(since the engine oil also lubricates
the clutch), do not mix any chemical
additives with oil. Do not use oils with
a diesel specification of “CD” or oils
of a higher quality than specified. In
addition, do not use oils labeled “EN-
ERGY CONSERVING II” or higher.
●
Make sure that no foreign material en-
ters the crankcase.
EVU00420CoolantCheck 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 between
the minimum and maximum level marks on
the coolant reservoir. If the coolant level is at
or below the minimum level mark, add addi-
tional coolant to bring the level up to maxi-
mum level mark. If coolant is not available,
add distilled water. Change the coolant every
two years. (See page 8-20 for details.)NOTICEHard water or salt water is harmful to the
engine. You may use soft water if you can-
not get distilled water.
Recommended engine oil type and
quantity: See page 10-1.
Coolant reservoir capacity
(up to the maximum level mark):0.28 L (0.30 US qt, 0.25 Imp.qt)

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.
10–20 hours:
Avoid prolonged operation above three-quar-
ter throttle.
After break-in:
The vehicle may now be operated normally.
5B410007Starting the engine1. Turn the key to “ ” (on).NOTICEThe 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 neutralposition.
●
When the drive select lever is in the
neutral position, the neutral indicator
light should come on. If the neutral in-
dicator light does not come on, ask a
Yamaha dealer to inspect the electric circuit.

WARNING
Before you shift into reverse, make sure
there are no obstacles or people behind
you. When it is safe to proceed, go slowly.
Hitting an obstacle or person could result
in serious injury or death.1. Stop the vehicle, take your foot off the ac- celerator pedal, and check behind you.
2. Apply the brake pedal.
3. Shift from neutral to reverse or vice versa
by moving the drive select lever along the
shift guide.
●
When in reverse, the reverse indicator
light should be on. If the light does not
come on, ask a Yamaha dealer to in-
spect the reverse indicator light elec-
trical circuit.
●
Due to the synchronizing mechanism
in the engine, the light may not come
on until the vehicle starts moving.
