EVU00390Front 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
8-35.)
●
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 pages 8-33–8-34.) Brake fluid leakage
Check to see if any brake fluid is leaking out of
the pipe joints or the brake fluid reservoir. Ap-
ply 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 prop-
er braking performance, inspect the brake
system. (See pages 8-32–8-33, 8-35–8-36.)
Specified brake fluid: DOT 4

EVU00400FuelMake sure there is sufficient fuel in the tank.
WARNING
Gasoline and gasoline vapors are ex-
tremely flammable. To avoid fires and ex-
plosions and to reduce the risk of injury
when refueling, follow these instructions.1. Before refueling, turn off the engine and be sure that no one is sitting in the vehi-
cle.
Never refuel while smoking, or while in
the vicinity of sparks, open flames, or oth-
er sources of ignition such as the pilot
lights of water heaters and clothes dry-
ers.
2. Do not overfill the fuel tank. Because fuel
expands when it heats up, heat from the
engine or the sun can cause fuel to spill
out of the fuel tank.
3. Wipe up any spilled fuel immediately. 4. Be sure the fuel tank cap is closed se-
curely.
WARNING
Gasoline is poisonous and can cause inju-
ry or death. Handle gasoline with care.
Never siphon gasoline by mouth. If you
should swallow some gasoline or inhale a
lot of gasoline vapor, or get some gasoline
in your eyes, see your doctor immediately.
If gasoline spills on your skin, wash with
soap and water. If gasoline spills on your
clothing, change your clothes.Your Yamaha engine has been designed to
use regular unleaded gasoline with a re-
search octane number of 91 or higher (95 or
higher for Europe). If knocking or pinging oc-
curs, use a different brand of gasoline or pre-
mium unleaded gasoline. Unleaded fuel will
give you longer spark plug life and reduced
maintenance cost.

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 vehi-
cle.
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.
Recommended fuel:
Regular unleaded gasoline only
For Europe:
Regular unleaded gasoline only with a re-
search octane number of 95 or higher
Fuel tank capacity: 36.7 L (9.70 US gal, 8.07 Imp.gal)

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)
