to the scooter as possible. Make
sure to distribute the weight as
evenly as possible on both sides
of the scooter to minimize imba-
lance or instability.
●Shifting weights can create a
sudden imbalance. Make sure
that accessories and cargo are
securely attached to the scooter
before riding. Check accessory
mounts and cargo restraints fre-
quently.
●Never attach any large or heavy
items to the handlebar, front fork,
or front fender. Such items can
create unstable handling or a
slow steering response.
Accessories
Genuine Yamaha accessories have
been specifically designed for use on
this scooter. Since Yamaha cannot
test all other accessories that may be
available, you must personally be res-
ponsible for the proper selection, ins-
tallation and use of non-Yamaha
accessories. Use extreme caution
when selecting and installing any
accessories.Keep the following guidelines in mind,
as well as those provided under “Loa-
ding” when mounting accessories.
●Never install accessories or carry
cargo that would impair the per-
formance of your scooter. Care-
fully inspect the accessory befo-
re using it to make sure that it
does not in any way reduce
ground clearance or cornering
clearance, limit suspension tra-
vel, steering travel or control ope-
ration, or obscure lights or reflec-
tors.
• Accessories fitted to the hand-
lebar or the front fork area can
create instability due to impro-
per weight distribution or
aerodynamic changes. If
accessories are added to the
handlebar or front fork area,
they must be as lightweight as
possible and should be kept to
a minimum.
• Bulky or large accessories may
seriously affect the stability of
the scooter due to aerodyna-
mic effects. Wind may attempt
to lift the scooter, or the scoo-ter may become unstable in
cross winds. These accesso-
ries may also cause instability
when passing or being passed
by large vehicles.
• Certain accessories can dis-
place the operator from his or
her normal riding position. This
improper position limits the fre-
edom of movement of the
operator and may limit control
ability, therefore, such acces-
sories are not recommended.
●Use caution when adding electri-
cal accessories. If electrical
accessories exceed the capacity
of the scooter’s electrical system
an electric failure could result,
which could cause a dangerous
loss of lights or engine power.
Gasoline and exhaust gas
●GASOLINE IS HIGHLY FLAMMA-
BLE:
• Always turn the engine off
when refueling.
• Take care not to spill any gaso-
line on the engine or exhaust
system when refueling.

Immobilizer system
1. Code re-registering key (red bow)
2. Standard keys (black bow)
This vehicle is equipped with an
immobilizer system to help prevent
theft by re-registering codes in the
standard keys. This system consists
of the following.
●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 (Electronic Control Unit)
●an immobilizer system indicator
light (See page 3-3.)The key with the red bow is used to
register codes in each standard key.
Since re-registering is a difficult pro-
cess, take the vehicle along with all
three keys to a Yamaha dealer to have
them re-registered. Do not use the
key with the red bow for driving. It
should only be used for re-registering
the standard keys. Always use a stan-
dard key for driving.
ECA11821
CAUTION:
●DO NOT LOSE THE CODE RE-
REGISTERING KEY! CONTACT
YOUR DEALER IMMEDIATELY IF
IT IS LOST! If the code re-regis-
tering key is lost, registering new
codes in the standard keys is
impossible. The standard keys
can still be used to start the vehi-
cle, however if code re-registe-
ring is required (i.e., if a new
standard key is made or all keys
are lost) the entire immobilizer
system must be replaced. There-
fore, it is highly recommended to
use either standard key and
keep the code re-registering key
in a safe place.
●Do not submerse any key in
water.
●Do not expose any key to
excessively 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 trans-
mit 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
immobilizer 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 sig-
nal interference.
