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.

Troubleshooting If a problem occurs, check the following
before taking the vehicle to a Yamaha
dealer. However, if no electric power is
supplied (nothing appears in the dis-
play), have a Yamaha dealer check the
vehicle.
The vehicle does not enter the
standby mode when the key is
turned to “ON”
Check the following:1. Is the vehicle currently being charged?
The vehicle does not enter the
standby mode when the key is
turned to “ON” during charging.
2. Was the key turned to “ON” while the accelerator grip was being
opened?
If the key is turned to “ON” while
the accelerator grip is opened, the
vehicle does not enter the standby
mode. Close the accelerator grip,
turn the key to “OFF” and then
back to “ON”.
If the vehicle still fails to enter the stand-
by mode, have a Yamaha dealer check the vehicle.
The vehicle does not start off
Is the vehicle in the riding mode? (Does
the operating status indicator “RUN”
appear in the display?)
The vehicle cannot be ridden unless it
is in the riding mode.
After checking the above, try starting off
again by following the procedures de-
scribed on page 7-1 “Preparations for
starting off” and page 7-3 “Starting off”
to restart the vehicle.
If the vehicle still does not start off, have
a Yamaha dealer check it.
The warning mark “ ” appears
Turn the key to “OFF” and then back to
“ON”. If the warning mark “ ” still ap-
pears, have a Yamaha dealer check
the vehicle.
TIPAlthough the warning mark appears,
the vehicle can still be ridden if the op-
erating status indicator “RUN” appearsand the vehicle is in the riding mode.
A light does not come on
Check the following:
1. Is the vehicle currently being charged? Lights do not come on if
the vehicle is being charged.
2. Is the key turned to “ON”? (Does anything appear in the display?)
If nothing appears in the display,
the auto-off function may be acti-
vated. Turn the key to “OFF” and
then back to “ON”.
3. Are all switches working properly?
After checking the above, and a light
does still not come on, proceed with the
following.

If the headlight fails to come on,
the bulb may be burned out. Refer
to page 8-11 for replacement pro-
cedures.

If a tail/brake light or turn signal
light fails to come on, a bulb may
be burned out. Refer to page 8-12
or 8-13 for replacement proce-
dures.
If a light still does not come on, a fuse
may be blown. Have a Yamaha dealer
check the vehicle.

NOTICE
ECA11982
Do not use a bulb of a wattage other
than specified to avoid causing ex-
tensive damage to the electrical sys-tem and possibly a fire.
The motor stops while riding
Check the following:1. Is the battery sufficiently charged? Check the battery level indicator. If
the remaining charge is insuffi-
cient, charge the battery before
continuing to ride.
2. Is “HEAT” flashing and did “RUN” go off?
The temperature protection func- tion has been activated. Turn the
key to “OFF”, and allow the vehicle
to cool down before continuing to
ride.
After checking the above, if the motor
still does not run, have a Yamaha deal-
er check the vehicle.
WARNING
EWA15631
Before pushing or moving the
EC-03, be sure to turn the key to
“OFF”. The vehicle may suddenly
start to move if the accelerator grip
is turned while the key is turned to“ON”.
The display and headlight go off
when the key is turned to “ON”
Check the following: 1. Has the vehicle been stopped for more than five minutes?
To protect the battery, the EC-03 is
equipped with an auto-off function.
If the vehicle has been stopped for
more than five minutes, the power
is cut to save the battery charge.
2. Is the battery sufficiently charged? If the remaining charge is insuffi- cient, charge the battery before
continuing to ride.
After checking the above, turn the key
to “ON” again. If the display and head-
light do not come on, have a Yamaha
dealer check the vehicle.
WARNING
EWA15631
Before pushing or moving the
EC-03, be sure to turn the key to
“OFF”. The vehicle may suddenly
start to move if the accelerator grip
is turned while the key is turned to“ON”.
The security lock cannot be un-
locked
If an incorrect security number is en-
tered three times in succession, the se-
curity lock cannot be unlocked even if
the correct security number is entered
after that.
Turn the key to “OFF” and then back to
“ON”, then try entering the correct se-
