SAFETY INFORMATION
1tice riding your scooter where
there is no traffic until you have
become thoroughly familiar with
the scooter and all of its con-
trols.

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 ex-
cessive speed or undercornering
(insufficient lean angle for the
speed).
Always obey the speed limit and
never travel faster than warrant-
ed 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 is im-
portant for proper control. The op-
erator should keep both hands on
the handlebar and both feet on the
operator footrests during operation
to maintain control of the scooter.

Do not place magnets or objects
with a strong magnetic force near
the accelerator grip. In addition, do
not place objects susceptible to
magnetic forces (i.e., credit cards, watches, etc.) close to the acceler-
ator grip.

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.
Avoid submerged roads
Do not ride on flooded roads. Water
could cause power unit failure, electric
leakage, and/or short-circuiting.
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 preven-
tion 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 ef-
fective 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 power unit become hot
during or after operation and can
cause burns.
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, acces-
sories and cargo must not exceed the
maximum load limit. Operation of an
overloaded vehicle could cause an
accident.

SAFETY INFORMATION
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 suspensionfor 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.
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 acces-
sories or offer other modifications for
Yamaha vehicles. Yamaha is not in a
position to test the products that these
aftermarket companies produce.
Therefore, Yamaha can neither en-
dorse nor recommend the use of ac-
cessories not sold by Yamaha or
modifications not specifically recom-
mended by Yamaha, even if sold and
installed by a Yamaha dealer.
Aftermarket Parts, Accessories,
and Modifications
While you may find aftermarket prod-
ucts similar in design and quality to genuine Yamaha accessories, recog-
nize that some aftermarket accessories
or modifications are not suitable be-
cause of potential safety hazards to you
or others. Installing aftermarket prod-
ucts or having other modifications per-
formed to your vehicle that change any
of the vehicle’s design or operation
characteristics can put you and others
at greater risk of serious injury or death.
You are responsible for injuries related
to changes in the vehicle.
Keep the following guidelines in mind,
as well as those provided under “Load-
ing” when mounting accessories.

Never install accessories or carry
cargo that would impair the perfor-
mance of your scooter. Carefully
inspect the accessory before using
it to make sure that it does not in
any way reduce ground clearance
or cornering clearance, limit sus-
pension travel, steering travel or
control operation, or obscure lights
or reflectors.
Accessories fitted to the handle-
bar or the front fork area can
create instability due to improper
weight distribution or aerody-

SAFETY INFORMATION
1namic 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 aerodynamic
effects. Wind may attempt to lift
the scooter, or the scooter may
become unstable in cross
winds. These accessories 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 free-
dom of movement of the opera-
tor and may limit control ability,
therefore, such accessories are
not recommended.

Use caution when adding electri-
cal accessories. If electrical acces-
sories exceed the capacity of the
scooter’s electrical system, an
electric failure could result, which
could cause a dangerous loss of lights or motor power.
Aftermarket 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 8-5 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 the
straps 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.

Traveling distance TIPThe distance that can be traveled on a
single charge varies according to the
riding and road conditions.
These conditions include the number of
starts and stops, vehicle load, the
steepness of slopes, road conditions,
wind direction and velocity, ambient
temperature, charging status, de-
creased battery performance, and lowtire air pressure.
Distance traveled on a single
charge
The data in the following chart was
measured at Yamaha Motor Co., Ltd. It
was measured when traveling with a
new battery at an ambient temperature
and vehicle load (total weight of rider
and luggage) as shown below on a dry
road surface in the absence of wind.
TIPThe maximum slope ascending capac-
ity is a gradient of approximately 16%(about 9 degrees).
Because of the battery character,
the riding distance might be re-

About the battery Lithium-ion (Li-ion) battery
The Li-ion battery used in the EC-03
features high energy density and has a
high voltage (approximately three times
that of nickel-cadmium (Ni-Cd) or nick-
el-hydrogen (Ni-MH) batteries), mean-
ing it can be made both compact and
lightweight.
Nickel-cadmium and nickel-hydrogen
batteries have a memory effect that
causes electric output capacity to de-
crease as a result of repeated partial
discharging and charging, so that they
need to have to be completely dis-
charged periodically. Li-ion batteries
can be repeatedly partially charged
without requiring fully discharging.TIP
It is not necessary to use up the
battery before charging.

The electric output capacity de-
creases over time and use, but the
rate at which it depletes depends
on condition of use.

The battery discharge may vary
depending on the ambient temper-ature. At low temperatures, the
traveling distance on a single
charge is reduced compared with
normal temperatures and charging
also takes longer. At low tempera-
tures, the electric output capacity
decreases, compared with normal
temperatures, and traveling dis-
tance on a single charge is re-
duced, but this is normal.

Storing the vehicle in an extremely
hot or cold place could decrease
the electric output capacity.

Even if the battery is not used, thebattery discharges gradually.
Recycling the battery
Li-ion batteries can be recycled. If the
electric output capacity decreases ex-
cessively due to depletion, have a
Yamaha dealer replace the battery. Al-
ways follow local regulations regarding
the disposal of batteries.

Tires Tires are the only contact between the
vehicle and the road. Safety in all con-
ditions of riding depends on a relatively
small area of road contact. Therefore, it
is essential to maintain the tires in good
condition at all times and replace them
at the appropriate time with the speci-
fied tires.
Tire air pressure
The tire air pressure should be checked
and, if necessary, adjusted before each
ride.
WARNING
EWA10511
Never overload your vehicle. Opera-
tion of an overloaded vehicle couldcause an accident.Tire inspection
The tires must be checked before each
ride. If the center tread depth reaches
the specified limit, if the tire has a nail or
glass fragments in it, or if the sidewall is
cracked, have a Yamaha dealer re-place the tire immediately.
TIPThe tire tread depth limits may differ
from country to country. Always complywith the local regulations.
Tire information
This vehicle is equipped with cast
wheels and tube tires.
Tires age, even if they have not been
used or have only been used occasion-
ally. Cracking of the tread and sidewall
rubber, sometimes accompanied by
carcass deformation, is an evidence of
ageing. Old and aged tires shall be
checked by tire specialists to ascertain
their suitability for further use.
After extensive tests, only the tires list-
ed below have been approved for this
