SAFETY INFORMATION
EAUT2031
Further safe-riding points 
Make sure to signal clearly when
making turns.

Braking can be extremely difficult
on a wet road. Avoid hard braking,
because the scooter could slide.
Apply the brakes slowly when
stopping on a wet surface.

Slow down as you approach a cor-
ner or turn. Once you have com-
pleted 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 construction
sites, and manhole covers be-
come extremely slippery when
wet. Slow down and cross them
with caution. Keep the scooter up-
right, otherwise it could slide out
from under you.

The brake lining could get wet
when you wash the scooter. After
washing the scooter, check the
brakes before riding.

Always wear a helmet, gloves,
trousers (tapered around the cuffand ankle so they do not flap), and
a bright colored jacket.

Do not carry too much luggage on
the scooter. An overloaded scoot-
er is unstable.
EAU50823
Charging the battery safely 
Do not charge the battery in areas
potentially exposed to rain or wa-
ter. This could cause an electric
shock or short circuit.

Be sure to plug the charging plug
only directly to a grounded electri-
cal outlet with residual-current de-
vice (RCD) protection to charge
the battery. If incorrectly grounded,
this could cause an electric shock
or short circuit.

If the vehicle is damaged due to
overturning or accident, do not
plug in the charging plug to an out-
let. This could cause an electric
shock or short circuit. Have your
vehicle checked by a Yamaha


If the charging cord or charging
plug is damaged, do not plug in to
an outlet. This could cause an
electric shock or short circuit. Have
your vehicle checked by a
Yamaha dealer as soon as possi-
ble.

EC-03 FEATURES
EAU50470
Features The features of the EC-03 are follow-
ing:
The driving power source is only
electricity and there is no need for
fuel supply or engine oil change.

High performance motor with
greatly reduced noise and vibra-
tion providing a pleasant ride.

Charging the vehicle can be done
via a grounded electrical outlet
with residual-current device (RCD)
protection.
EAU53920
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-

duced according to the ambient
temperature due to changes of the
battery temperature.

The distance that can be traveled
becomes 5–10% shorter when the
vehicle load is increased 10 kg.
EAU50344
Effective use of
the battery If the battery is left nearly fully charged
(4–5 segments shown on the battery
charge indicator) and exposed to high
temperature for an extended period, it
will rapidly deplete. To extend the bat-
tery life, handle as follows:
Choose a cool place with no direct
sunlight when charging the bat-
tery.

Do not store the battery with a
charge less than 20% (below the
last segment of the battery level in-
dicator) for an extended period of
time.

Choose a cool and well-ventilated
place without direct sunlight for
storing the vehicle.

When not used for a long period of
time, charge the battery until the
2–3 segments of the battery
charge indicator are shown and
then store the vehicle in a cool
place (optimum temperature 15  C
– 25 C). Check the battery level
while the vehicle is in storage. If
the battery level drops to the last
segment, recharge the battery until 2–3 segments of the battery
charge indicator are shown.
NOTICE
ECA17072
If the battery is discharged until the
battery is depleted, recharging will
not be possible and the battery willnot be usable.

Battery level TIPBe sure to check the battery level be-fore each ride.
Checking the battery level
Check the number of segments dis-
played in the battery level indicator.TIPWhile charging the battery, the indica-
tor shows the progress status of charg-
ing. This differs from the indication of
remaining charge when the vehicle is inuse. See page 6-9.
Battery level indicator
When the key is turned to “ON”, all seg-
ments of the battery level indicator
come on for a few seconds, and then
show a general indication of the re-
maining battery charge corresponding
to the amount of the electric output.

CHARGING THE BATTERY
EAU50561
WARNING
EWA15761

If the vehicle is damaged due to
overturning or accident, do not
plug in the charging plug to the
outlet. Otherwise it could cause
an electric shock or short cir-
cuit. Have a Yamaha dealer
check the charging plug before
charging the battery.

Charge the vehicle where no
rain can get to it, as this could
cause an electric shock or short
circuit.

Be sure to plug in the charging
plug to a grounded electrical
outlet with residual-current de-
vice (RCD) protection for charg-
ing the battery. If grounded
incorrectly, this could cause an
electric shock or short circuit.

Do not remove the plastic cover
under the seat to check the bat-
tery or built-in battery charger
as this increases the risk of an
electric shock or short circuit. If
any problem is found, have aYamaha dealer check the vehi-
cle.

Battery charging location
WARNING
EWA15872
Charging the battery incorrectly can
cause electric shock or fire. Serious
injury or death can occur if you ig-
nore any of the following:
Read all instructions and labels
before charging the battery.

Choose a dry location with a
flat, stable surface that is pro-
tected from rain or water spray.
The area must have good venti-
lation and be free of flammable
objects or sources of heat.

Be sure the vehicle, charging
cord, and charging plug will not
be disturbed by children or oth-
er bystanders, or animals.

Connect the charging plug only
directly to a grounded electrical
outlet with residual-current de-
vice (RCD) protection. Do not
use an ungrounded extension
cord or multi-outlet plug with
the charging cord.


aged due to overturn or acci-

cord. Have your vehicle
checked by a Yamaha dealer as
soon as possible.
NOTICE
ECA17451
Improper charging can damage the
battery and built-in battery charger.
Do not charge in a place ex- posed to direct sunlight or near
a heater.

Do not charge when there is risk
of thunderstorms or lightning.
Electrical surges could cause
damage.

Do not use the AC outlet of a car
or generator for charging the
battery as this could cause amalfunction.
Park the vehicle on a flat, stable sur-
face near a grounded electrical outlet
with residual-current device (RCD) pro-
tection. The area must be dry and, if
necessary, sheltered to prevent rain
water or other moisture from wetting
the vehicle, charging cord, or outlet.
The environment affects the duration of
battery charging. For optimum charg-
ing, charge the battery out of direct sun-
light in an ambient temperature of 15 C
– 25 C.
TIPAlthough charging between 15 C – 25
 C provides the best results, the battery
can be charged within an ambient tem-
perature range of –5 C – 50 C. A de-
pleted battery cannot be charged if
ambient temperature is below 0 C.
Examples of recommended charg-
ing locations
A cool, shaded and well-ventilated
place.
A place that does not fall below –5 C
overnight.
