●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 footboard
during operation to maintain
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 foo-
trests.
• Never carry a passenger
unless he or she can firmly pla-
ce both feet on the passenger
footrests.
●Never ride under the influence 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 hel-
met.
●Wear a face shield or goggles.
Wind in your unprotected eyes
could contribute to an impair-
ment of vision which could delay
seeing a hazard.
●The use of a jacket, substantial
shoes, trousers, gloves, etc., is
effective in preventing or redu-
cing abrasions or lacerations.
●Never wear loose-fitting clothes,
otherwise they could catch on
the control levers or wheels and
cause injury or an accident.
●Never touch the engine or
exhaust system during or after
operation. They become very hot
and can cause burns. Always
wear protective clothing that
covers your legs, ankles, and
feet.
●Passengers should also observe
the above precautions.
Modifications
Modifications made to this scooter
not approved by Yamaha, or the
removal of original equipment, may
render the scooter unsafe for use andmay cause severe personal injury.
Modifications may also make your
scooter illegal to use.
Loading and accessories
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 accessories to your scooter. Use
extra care when riding a scooter that
has added cargo or accessories. Here
are some general guidelines to follow
if loading cargo or adding accessories
to your scooter:
Loading
The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.
When loading within this weight limit,
keep the following in mind:
●Cargo and accessory weight
should be kept as low and close
Maximum load:
189 kg (417 lb)

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.

• Never refuel while smoking or
in the vicinity of an open flame.
●Never start the engine or let it run
for any length of time in a closed
area. The exhaust fumes are poi-
sonous and may cause loss of
consciousness and death within
a short time. Always operate your
scooter in an area that has ade-
quate ventilation.
●Always turn the engine off before
leaving the scooter unattended
and remove the key from the
main switch. When parking the
scooter, note the following:
• The engine and exhaust sys-
tem may be hot, therefore,
park the scooter in a place
where pedestrians or children
are not likely to touch these hot
areas.
• Do not park the scooter on a
slope or soft ground, otherwise
it may fall over.
• Do not park the scooter near a
flammable source (e.g., a kero-
sene heater, or near an open
flame), otherwise it could catch
fire.
●If you should swallow any gasoli-
ne, inhale a lot of gasoline vapor,
or allow gasoline to get into your
eyes, see your doctor immedia-
tely. If any gasoline spills on your
skin or clothing, immediately
wash the affected area with soap
and water and change your clot-
hes.EAU10371
Further safe-riding points
●Be sure to signal clearly when
making turns.
●Braking can be extremely difficult
on a wet road. Avoid hard bra-
king, because the scooter could
slide. Apply the brakes slowly
when stopping on a wet surface.
●Slow down as you approach a
corner or turn. Once you have
completed 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 cons-
truction sites, and manhole
covers become extremely slip-
pery when wet. Slow down and
cross them with caution. Keep
the scooter upright, 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.
