The electrical circuit of the warning light
can be checked by turning the key to
“ON”. The warning light should come
on for a few seconds, and then go off.
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.

WARNING
EWA11091
Make sure that the fuel tank cap is
properly closed after filling fuel.
Leaking fuel is a fire hazard.
EAU13221
Fuel Make sure there is sufficient gasoline in
the tank.
WARNING
EWA10881
Gasoline and gasoline vapors are
extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, follow
these instructions.1. Before refueling, turn off the en-
gine and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the vi-
cinity of sparks, open flames, or
other sources of ignition such as
the pilot lights of water heaters and
clothes dryers.
2. Do not overfill the fuel tank. When
refueling, be sure to insert the
pump nozzle into the fuel tank filler
hole. Stop filling when the fuel
reaches the bottom of the filler
tube. 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 immedi-
ately. NOTICE: Immediately wipe
off spilled fuel with a clean, dry,
soft cloth, since fuel may deteri-
orate painted surfaces or plastic
parts.
[ECA10071]
4. Be sure to securely close the fuel
tank cap.
WARNING
EWA15151
Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gaso-
line by mouth. If you should swallow
some gasoline or inhale a lot of gas-
oline vapor, or get some gasoline in
your eyes, see your doctor immedi-1. Fuel tank filler tube

wash with soap and water. If gaso-
line spills on your clothing, change
your clothes.

NOTICE
ECA11400
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,
as well as to the exhaust system.Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
95 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a different brand
or premium unleaded fuel. Use of un-
leaded fuel will extend spark plug life
and reduce maintenance costs.
EAU13445
Catalytic converters This vehicle is equipped with catalytic
converters in the exhaust system.
WARNING
EWA10862
The exhaust system is hot after op-
eration. To prevent a fire hazard or
burns:●
Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.
●
Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.
●
Make sure that the exhaust sys-
tem has cooled down before do-
ing any maintenance work.
●
Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up of
heat.
NOTICE
ECA10701
Use only unleaded gasoline. The use
of leaded gasoline will cause unre-
pairable damage to the catalytic
converter.
Recommended fuel:
Regular unleaded gasoline only

tion, turn the key counterclockwise
to the second “OPEN” position.TIPDo not push inward when turning the
key from “OFF” to “OPEN” or from
“LOCK” to “OPEN”.3. Fold the seat up.To close the seat

Storage compartments NOTICE
ECA17840
Keep the following points in mind
when using the storage compart-
ments.●
Since the storage compart-
ments accumulate heat when
exposed to the sun and/or the
engine heat, do not store any-
thing susceptible to heat, con-
sumables or flammable items
inside them.
●
To avoid humidity from spread-
ing through the storage com-
partments, wrap wet articles in a
plastic bag before storing them
in the compartments.
●
Since the storage compart-
ments may get wet while the ve-
hicle is being washed, wrap any
articles stored in the compart-
ments in a plastic bag.
●
Do not keep anything valuable
or breakable in the storage com-
partments.

Sidestand The sidestand is located on the left side
of the frame. Raise the sidestand or
lower it with your foot while holding the
vehicle upright.TIPThe built-in sidestand switch is part of
the ignition circuit cut-off system, which
cuts the ignition in certain situations.
(See the following section for an expla-
nation of the ignition circuit cut-off sys-
tem.)
WARNING
EWA10241
The vehicle must not be ridden with
the sidestand down, or if the side-
stand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control.
Yamaha’s ignition circuit cut-off
system has been designed to assist
the operator in fulfilling the respon-
sibility of raising the sidestand be-
fore starting off. Therefore, check
this system regularly and have a
Yamaha dealer repair it if it does not
function properly.
EAU15373
Ignition circuit cut-off system The ignition circuit cut-off system (com-
prising the sidestand switch and brake
light switches) has the following func-
tions.●
It prevents starting when the side-
stand is up, but neither brake is ap-
plied.
●
It prevents starting when either
brake is applied, but the sidestand
is still down.
●
It cuts the running engine when the
sidestand is moved down.
Periodically check the operation of the
ignition circuit cut-off system according
to the following procedure.
TIPThis check is most reliable if performed
with a warmed-up engine.
