Immobilizer system
1. Code re-registering key (red bow)
2. Standard keys (black bow)
This vehicle is equipped with an im-
mobilizer system to help prevent theft
by re-registering codes in the standard
keys. This system consists of the fol-
lowing.
●a code re-registering key (with a
red bow)
●two standard keys (with a black
bow) that can be re-registered
with new codes
●a transponder (which is installed
in the code re-registering key)
●an immobilizer unit
●an ECU
●an immobilizer system indicator
light (See page 4-3.)
The key with the red bow is used to reg-
ister codes in each standard key. Since
re-registering is a difficult process, take
the vehicle along with all three keys to a
Yamaha dealer to have them re-regis-
tered. Do not use the key with the red
bow for driving. It should only be used
for re-registering the standard keys. Al-
ways use a standard key for driving.
ECA11821NOTICE
●DO NOT LOSE THE CODE RE-
REGISTERING KEY! CONTACT
YOUR DEALER IMMEDIATELY
IF IT IS LOST! If the code re-reg-
istering key is lost, registering
new codes in the standard keys
is impossible. The standard keys
can still be used to start the ve-
hicle, however if code re-regis-
tering is required (i.e., if a new
standard key is made or all keys
are lost) the entire immobilizer
system must be replaced.
Therefore, it is highly recom-
mended to use either standardkey and keep the code re-regis-
tering key in a safe place.
●Do not submerse any key in water.
●Do not expose any key to exces-
sively high temperatures.
●Do not place any key close to
magnets (this includes, but not
limited to, products such as
speakers, etc.).
●Do not place items that transmit
electrical signals close to any key.
●Do not place heavy items on
any key.
●Do not grind any key or alter its
shape.
●Do not disassemble the plastic
part of any key.
●Do not put two keys of any immobi-
lizer system on the same key ring.
●Keep the standard keys as well
as keys of other immobilizer
systems away from this vehi-
cle's code re-registering key.
●Keep other immobilizer system
keys away from the main switch
as they may cause signal inter-
ference.

To close the fuel tank cap
1. Push the fuel tank cap into posi-
tion with the key inserted in the
lock.
2. Turn the key counterclockwise to
the original position, remove it,
and then close the lock cover.

EWA11091
WARNING0
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.
EWA10881
WARNING0
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
sitting on the vehicle. Never refuel
while smoking, or while in the
vicinity 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 fu-
el 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.
1. Fuel tank filler tube
2. Fuel level
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 plas-
tic parts.
4. Be sure to securely close the fuel
tank cap.
EWA15151
WARNING0
Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gaso-
line by mouth. If you should swal-
low some gasoline or inhale a lot of
gasoline vapor, or get some gaso-
line in your eyes, see your doctor
immediately. If gasoline spills on
