ducts similar in design and quality to
genuine Yamaha accessories, recog-
nize that some aftermarket accesso-
ries or modifications are not suitable
because of potential safety hazards to
you or others. Installing aftermarket
products or having other modifica-
tions performed to your vehicle that
change any of the vehicle’s design or
operation characteristics can put you
and others at greater risk of serious
injury or death. You are responsible
for injuries related to changes in the
vehicle.
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 ope-
rator and may limit control abi-
lity, therefore, such acces-
sories are not recommended. Use caution when adding elec-
trical accessories. If electrical
accessories exceed the capa-
city of the scooter’s electrical
system, an electric failure
could result, which could cau-
se a dangerous loss of lights or
engine power.
Aftermarket Tires and Rims
The tires and rims that came with your
scooter were designed to match the
performance capabilities and to pro-
vide the best combination of hand-
ling, braking, and comfort. Other tires,
rims, sizes, and combinations may
not be appropriate. Refer to page
6-18 for tire specifications and more
information on replacing your tires.
EWA15470
Be sure to observe following ins-
tructions before transporting the
scooter in another vehicle.
Remove all loose items from
the scooter.

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
an immobilizer system indicator
light (See page 3-4).
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
DO NOT LOSE THE CODE RE-
REGISTERING KEY! CONTACT
YOUR DEALER IMMEDIATELY
IF IT IS LOST! If the code re-
registering key is lost, registe-
ring new codes in the standard
keys is impossible. The stan-
dard keys can still be used to
start the vehicle, however if
code re-registering 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 ishighly 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

nal interference.

Main switch/steering lock
The main switch/steering lock con-
trols the ignition and lighting systems,
and is used to lock the steering. The
various positions are described
below.
TIP
Be sure to use the standard key
(black bow) for regular use of the
vehicle. To minimize the risk of losing
the code re-registering key (red bow),
keep it in a safe place and only use it
for code re-registering.
