SAFETY INFORMATION

1Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon
monoxide, a deadly gas. Breathing car-
bon monoxide can cause headaches,
dizziness, drowsiness, nausea, confu-
sion, and eventually death.
Carbon Monoxide is a colorless, odor-
less, tasteless gas which may be
present even if you do not see or smell
any engine exhaust. Deadly levels of
carbon monoxide can collect rapidly
and you can quickly be overcome and
unable to save yourself. Also, deadly
levels of carbon monoxide can linger
for hours or days in enclosed or poorly
ventilated areas. If you experience any
symptoms of carbon monoxide poison-
ing, leave the area immediately, get
fresh air, and SEEK MEDICAL TREAT-
MENT.
●
Do not run engine indoors. Even if
you try to ventilate engine exhaust
with fans or open windows and
doors, carbon monoxide can rap-
idly reach dangerous levels.
●
Do not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or car-
ports.
●
Do not run engine outdoors where
engine exhaust can be drawn into
a building through openings such
as windows and doors.
Loading
Adding accessories or cargo to your
scooter can adversely affect stability
and handling if the weight distribution of
the scooter is changed. To avoid the
possibility of an accident, use extreme
caution when adding cargo or accesso-
ries to your scooter. Use extra care
when riding a scooter that has added
cargo or accessories. Here, along with
the information about accessories be-
low, are some general guidelines to fol-
low if loading cargo to your scooter:
The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.
Operation of an overloaded vehicle
could cause an accident.
When loading within this weight limit,
keep the following in mind:
●
Cargo and accessory weight
should be kept as low and close to
the scooter as possible. Securely
pack your heaviest items as close
to the center of the vehicle as pos-
sible and make sure to distribute
the weight as evenly as possible
on both sides of the scooter to min-
imize imbalance or instability.
●
Shifting weights can create a sud-
den imbalance. Make sure that ac-
cessories and cargo are securely
attached to the scooter before
riding. Check accessory mounts
and cargo restraints frequently.
Properly adjust the suspension
for your load (suspension-ad-
justable models only), and
check the condition and pres-
sure of your tires.
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.
●
This vehicle is not designed to
pull a trailer or to be attached to
a sidecar.
Maximum load:
185 kg (408 lb)

1Aftermarket Tires and Rims
The tires and rims that came with your
scooter were designed to match the
performance capabilities and to provide
the best combination of handling, brak-
ing, and comfort. Other tires, rims, siz-
es, and combinations may not be
appropriate. Refer to page 6-17 for tire
specifications and more information on
replacing your tires.
Transporting the Scooter
Be sure to observe following instruc-
tions before transporting the scooter in
another vehicle.
●
Remove all loose items from the
scooter.
●
Point the front wheel straight
ahead on the trailer or in the truck
bed, and choke it in a rail to pre-
vent movement.
●
Secure the scooter with tie-downs
or suitable straps that are attached
to solid parts of the scooter, such
as the frame or upper front fork tri-
ple clamp (and not, for example, to
rubber-mounted handlebars or
turn signals, or parts that could
break). Choose the location for thestraps carefully so the straps will
not rub against painted surfaces
during transport.
●
The suspension should be com-
pressed somewhat by the tie-
downs, if possible, so that the
scooter will not bounce excessive-
ly during transport.
EAU10373
Further safe-riding points ●
Be sure to signal clearly when
making turns.
●
Braking can be extremely difficult
on a wet road. Avoid hard braking,
because the scooter could slide.
Apply the brakes slowly when
stopping on a wet surface.
●
Slow down as you approach a cor-
ner or turn. Once you have com-
pleted a turn, accelerate slowly.
●
Be careful when passing parked
cars. A driver might not see you
and open a door in your path.
●
Railroad crossings, streetcar rails,
iron plates on road construction
sites, and manhole covers be-
come extremely slippery when
wet. Slow down and cross them
with caution. Keep the scooter up-
right, otherwise it could slide out
from under you.
●
The brake pads could get wet
when you wash the scooter. After
washing the scooter, check the
brakes before riding.

●
Always wear a helmet, gloves,
trousers (tapered around the cuff
and ankle so they do not flap), and
a bright colored jacket.
●
Do not carry too much luggage on
the scooter. An overloaded scoot-
er is unstable. Use a strong cord to
secure any luggage to the carrier
(if equipped). A loose load will af-
fect the stability of the scooter and
could divert your attention from the
road. (See page 1-3.)

Immobilizer system This vehicle is equipped with an immo-
bilizer 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 3-3.)
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-reg-
istered. 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.
NOTICE
ECA11821
●
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 vehicle, however if code re-
registering is required (i.e., if a
new standard key is made or all
keys are lost) the entire immobi-
lizer system must be replaced.
Therefore, it is highly recom-mended to use either standard
key and keep the code re-regis-
tering key in a safe place.
●
Do not submerse any key in wa-
ter.
●
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 im-
mobilizer 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.
