seconds, and the charging
progress status is shown.
TIP
The battery may be above the
maximum 50 C suitable for charg-
ing immediately after riding. In this
case, the charger enters a waiting
mode and “HEAT” flashes until the
battery and battery charger reach
the specified temperature. Charg-
ing then starts automatically.

If ambient temperature is below
–5 C, “COOL” flashes and the
vehicle enters a waiting mode un-
til the battery and battery charger
reach the specified temperature.
Charging then starts automatical-
ly.

If the battery is already fully
charged when the charging plug is
plugged in, the display will show
the fully charged status for a few
minutes and then go off. The bat-
tery charger will not charge thebattery further.
10. The battery charging status can be
checked in the display. (See page
6-9 for more information about the
charging status display.)

started by unplugging or plugging
in the charging plug.

Completing charging
When the battery is fully charged, the
display goes off automatically after a
few minutes.
1. Grasp the charging plug, and then
unplug it from the electrical outlet.
NOTICE: Do not pull the charg-
ing cord to unplug the charging
plug from the electrical outlet.
This could damage the charging
cord.

2. Open the seat. (See page 4-12 for
more information.)
3. Hold the charging plug, and while
pressing the charging cord into the
groove, wind it clockwise as
shown. NOTICE: If the charging
cord is not wound properly, the
vehicle, charging cord or charg-ing plug can be damaged when
closing the seat.

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.

stops sounding when either brake lever
is squeezed or the vehicle starts mov-ing.
If the entered security number is
incorrect, the buzzer sounds, “NG”
flashes for a few seconds, and the
vehicle returns to the standby
mode.

Braking
WARNING
EWA10300

Avoid braking hard or suddenly
(especially when leaning over to
one side), otherwise the scooter
may skid or overturn.

Railroad crossings, streetcar
rails, iron plates on road con-
struction sites, and manhole
covers become extremely slip-
pery when wet. Therefore, slow
down when approaching such
areas and cross them with cau-
tion.

Keep in mind that braking on a
wet road is much more difficult.

Ride slowly down a hill, as brak-
ing downhill can be very diffi-cult.
1. Close the accelerator grip com-
pletely.
2. Apply both front and rear brakes
simultaneously while gradually in-
creasing the pressure.Front

Parking To prevent theft, be sure to lock the
steering and remove the key when
parking. It is recommended to addition-
ally use a chain lock or other type of
motorcycle lock.
WARNING
EWA15580
Do not park on a slope or on soft
ground, otherwise the vehicle mayoverturn.TIP
If the vehicle is parked in an ex-
tremely hot or cold place, the tem-
perature protection function may
be activated when the key is
turned to “ON”. If this is activated,
“HEAT” or “COOL” flashes on the
tripmeter/odometer display. (See
page 4-4 “Temperature warning
display” for more information about
the temperature protection func-
tion.)

It is recommended to lock the se-
curity lock when parking. (See
page 4-10 for more informationabout locking the security lock.)

certain motor speed by turning the ac-
celerator grip when the vehicle is on thecenterstand.
EAU50154
Checking the accelerator grip Before checking the accelerator grip,
check the following points.
Make sure that the key is in the
“OFF” position. Turn the accelera-
tor grip slowly and check that it
moves smoothly, and returns
smoothly when released.

Check for any signs of deteriora-
tion or damage around the accel-
erator grip. Also check the
accelerator grip holder mounting
bolts for tightness.

When washing the vehicle, avoid
spraying the area around the ac-
celerator grip with water. If the
area around the accelerator grip is
particularly dirty, use a well-wrung
damp cloth to clean.
WARNING
EWA15671
If a problem is found in accelerator
grip operation, do not operate the
vehicle. Have the vehicle inspected
by a Yamaha dealer. Continuing to
use the vehicle with a problem in-
creases the possibility of an acci-dent or equipment damage.
1. Squeeze the rear brake lever with
your left hand.
2. Turn the key to “ON”.
3. Cancel the standby mode by
pressing one of the control but-
tons. (See page 4-3.)
4. Make sure that the operating sta-
tus indicator “RUN” is displayed,
and that the vehicle is in the riding
mode. (See page 7-1 for more in-
formation about “Preparations for
starting off” and “Starting off”.)
5. Check that the accelerator grip
and motor operate smoothly when
the vehicle is accelerated by grad-
ually turning the accelerator grip
while riding the vehicle. If there is a
problem, have a Yamaha dealer
check the vehicle.
