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.
