Using the security lock The EC-03 is equipped with a security
lock that can be used by registering a
security number. Once the security
number has been set, the vehicle can-
not be ridden unless the correct securi-
ty number is entered, even if the key is
turned to “ON”.

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.)
11. Charging can be stopped or re-
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.

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.
