SAFETY INFORMATION
EAU10269
Be a Responsible Owner
As the vehicle’s owner, you are re-
sponsible for the safe and proper op-
eration of your scooter.
Scooters are single-track vehicles.
Their safe use and operation are de-
pendent upon the use of proper riding
techniques as well as the expertise of
the operator. Every operator should
know the following requirements be-
fore riding this scooter.
He or she should:● Obtain thorough instructions from
a competent source on all as-
pects of scooter operation.● Observe the warnings and main-
tenance requirements in this
Owner’s Manual.● Obtain qualified training in safe
and proper riding techniques.● Obtain professional technical ser-
vice as indicated in this Owner’s
Manual and/or when made nec-
essary by mechanical conditions.
Safe Riding
Perform the pre-operation checks
each time you use the vehicle to make sure it is in safe operating condition.
Failure to inspect or maintain the ve-
hicle properly increases the possibility
of an accident or equipment damage.
See page 4-2 for a list of pre-opera-
tion checks.
● This scooter is designed to carry
the operator and a passenger.● The failure of motorists to detect
and recognize scooters in traf-
fic is the predominating cause
of automobile/scooter accidents.
Many accidents have been
caused by an automobile driver
who did not see the scooter. Mak-
ing yourself conspicuous appears
to be very effective in reducing
the chance of this type of acci-
dent.
Therefore:
• Wear a brightly colored jacket.
• Use extra caution when you
are approaching and passing
through intersections, since in-
tersections are the most likely
places for scooter accidents to
occur.• Ride where other motorists can
see you. Avoid riding in another
motorist’s blind spot.
● Many accidents involve inexpe-
rienced operators. In fact, many
operators who have been in-
volved in accidents do not even
have a current driver’s license.
• Make sure that you are quali-
fi ed and that you only lend your
scooter to other qualified op-
erators.
• Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
• We recommend that you prac-
tice riding your scooter where
there is no traffi c until you have
become thoroughly familiar
with the scooter and all of its
controls.● Many accidents have been
caused by error of the scooter
operator. A typical error made by
the operator is veering wide on
a turn due to excessive speed or
undercornering (insufficient lean
angle for the speed).

Q
SAFETY INFORMATION
• Always obey the speed limit
and never travel faster than
warranted by road and traffic
conditions.
• Always signal before turning or
changing lanes. Make sure that
other motorists can see you.
● The posture of the operator and
passenger is important for proper
control.
• The operator should keep both
hands on the handlebar and
both feet on the operator foot-
rests during operation to main-
tain control of the scooter.
• The passenger should always
hold onto the operator, the seat
strap or grab bar, if equipped,
with both hands and keep both
feet on the passenger foot-
rests. Never carry a passenger
unless he or she can firmly
place both feet on the passen-
ger footrests.● Never ride under the infl uence of
alcohol or other drugs.● This scooter is designed for on-
road use only. It is not suitable for off-road use.
Protective Apparel
The majority of fatalities from scooter
accidents are the result of head inju-
ries. The use of a safety helmet is the
single most critical factor in the pre-
vention or reduction of head injuries.
● Always wear an approved helmet.● Wear a face shield or goggles.
Wind in your unprotected eyes
could contribute to an impairment
of vision that could delay seeing a
hazard.● The use of a jacket, substantial
shoes, trousers, gloves, etc., is
effective in preventing or reducing
abrasions or lacerations.● Never wear loose-fitting clothes,
otherwise they could catch on
the control levers or wheels and
cause injury or an accident.● Always wear protective clothing
that covers your legs, ankles,
and feet. The engine or exhaust
system become very hot during
or after operation and can cause
burns.
● A passenger should also observe
the above precautions.
Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon
monoxide, a deadly gas. Breathing
carbon monoxide can cause head-
aches, dizziness, drowsiness, nausea,
confusion, and eventually death.
Carbon Monoxide is a colorless,
odorless, 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 over-
come and unable to save yourself.
Also, deadly levels of carbon mon-
oxide can linger for hours or days in
enclosed or poorly ventilated areas.
If you experience any symptoms of
carbon monoxide poisoning, leave the
area immediately, get fresh air, and
SEEK MEDICAL TREATMENT.●
Do not run engine indoors. Even
if you try to ventilate engine ex-
haust with fans or open windows
and doors, carbon monoxide can
rapidly reach dangerous levels.

Q
SAFETY INFORMATION●
Do not run engine in poorly ven-
tilated 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 ex-
treme caution when adding cargo or
accessories to your scooter. Use extra
care when riding a scooter that has
added cargo or accessories. Here,
along with the information about ac-
cessories below, are some general
guidelines to follow if loading cargo to
your scooter:
The total weight of the operator,
passenger, accessories and cargo
must not exceed the maximum load
limit. Operation of an overloaded
vehicle could cause an accident.
Maximum load:
157 kg (346 lb)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. Se-
curely pack your heaviest items
as close to the center of the ve-
hicle as possible and make sure
to distribute the weight as evenly
as possible on both sides of the
scooter to minimize imbalance 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.
• Properly adjust the suspen-
sion for your load (suspension-
adjustable 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 re-
sponse.
●
This vehicle is not designed to
pull a trailer or to be attached
to a sidecar.
Genuine Yamaha Accessories
Choosing accessories for your vehicle
is an important decision. Genuine
Yamaha accessories, which are avail-
able only from a Yamaha dealer, have
been designed, tested, and approved
by Yamaha for use on your vehicle.
Many companies with no connection
to Yamaha manufacture parts and ac-
cessories or offer other modifications
for Yamaha vehicles. Yamaha is not
in a position to test the products that
these aftermarket companies pro-
duce. Therefore, Yamaha can neither
endorse nor recommend the use of
accessories not sold by Yamaha or
modifications not specifically recom-
mended by Yamaha, even if sold and
installed by a Yamaha dealer.
