If a problem is detected, the warning
light comes on. In this case, check for
the warning mark “ ”. If this warning
mark also appears, have a Yamaha
dealer check the vehicle.
Warning mark “ ”
This warning mark flashes if a problem
is detected. If the warning mark keeps
flashing after turning the key to “OFF”
and then back to “ON”, have a Yamaha
dealer check the vehicle.TIPAfter turning the key to “ON”, the warn-
ing mark appears. If the warning mark
goes out after a few seconds, there isno malfunction. Go ahead with riding.
EAU50034
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”.
Registering and changing the secu-
rity number
WARNING
EWA15611
Be sure to stop the vehicle before
registering or changing the security
number. Changing settings while
riding can distract the operator andincrease the risk of an accident.TIPThe security number registration/
change mode is canceled if the regis-
tering procedure is not completed in
one minute. If the mode cancels, repeatthe procedure.
1. Turn the key to “ON”. All display segments appear for a
few seconds, then the vehicle en- ters the standby mode and
“PUSH” flashes.
TIPWhen the security lock has been
locked, the security number indicator
“ LOCK” appears when the vehicle isin the standby mode.
2. Change to the riding mode by pushing any of the buttons.1. Security lock indicator “ LOCK”

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.

Charging procedure
WARNING
EWA15692

Do not handle the charging plug
with wet hands. You could be
electrocuted.

Do not charge the battery if any
damage, corrosion, rust or
looseness is found with the
charging plug, charging cord or
grounded electrical outlet. This
could cause a fire, electric
shock or short circuit.

If any unusual odor or smoke
emerges from the vehicle dur-
ing charging, stop charging the
battery immediately and consult
your Yamaha dealer.

Electromagnetic waves emitted
from the battery charger could
interfere with the function of
heart devices or other electrical
medical equipment and cause
injury. If you use an im-
plant-type cardiac pacemaker or
defibrillator, or other electrical
medical device, be sure to con-
sult with your doctor or the manufacturer to check whether
being near the battery charger
could affect the device.WARNING
EWA15881
Do not use the charging cord or
charging plug if damaged (i.e., bro-
ken or exposed leads) because it
could cause electric shock or fire. If
such damage is found on the charg-
ing cord, stop using it immediately
and have a Yamaha dealer check the
vehicle. Handle the charging cord
carefully by observing the following:
Do not twist the charging cord,
wrap it into a tight loop, or sub-
ject it to sharp bends.

Be sure the charging cord can-
not be caught in a door or win-

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.
