• 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 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 footrests.
• 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 and
may 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.

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.
