9Battery depletion
The electric output capacity of the
Li-ion battery used in the EC-03 gradu-
ally decreases in the course of use. Al-
though the extent of depletion varies
based on the conditions of use, electric
output capacity typically decreases to
70% of a new battery when having trav-
eled 8000–10000 km for two years.
This is equivalent to charging about
500 times with the condition of riding
16–20 km on a single charge.
Battery electric output auto-stop-
ping function
The battery is equipped with a function
to prevent further use in case of exces-
sive depletion. When eight years have
passed since initial battery charging or the accumulated charging amount has
reached 14000 Ah, the battery will no
longer be usable.
TIP
When the battery is replaced with
a new one, fully charge the battery
once before using it. If the battery
is not fully charged, the battery lev-
el indicator does not show the pre-
cise battery level.

At low temperatures such as 0
C,
the electric output capacity de-
creases by approximately 20%
compared with normal tempera-
ture.

If a depleted battery is used at low
temperatures, the electric output
capacity decreases by approxi-
mately 20% compared with normaltemperatures.

TIPWhen the vehicle enters the riding
mode, the beeper sounds. The beeper
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.
If this occurs, repeat the procedure
from the step 6.TIPIf 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.
Repeat the procedure after first turning
the key to “OFF” and then back to “ON”
again.
8. Check the battery level indicator to make sure that the remaining
charged level is sufficient. (See
page 3-3 for more information
about the charge level.)

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

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

and the warning mark “ ” flash.
TIPIf this continues for five minutes, the
warning light goes off, along with all in-dicators in the display.
Unplug the charging plug from the out-
let to stop charging, and then start
charging again after waiting a few min- utes. If charging automatically stops
again, there may be a malfunction with
the vehicle. Stop charging and have a

“HEAT” flashes in the display dur-
ing charging
This is not a malfunction. The charging process is in the standby
mode because the battery temperature
is higher than 50
C. Allow the battery
to cool down.
When the battery temperature falls to
the specified temperature, “HEAT”
goes off and charging starts automati-
cally. (See page 6-1 for more informa-
tion about “Battery charging place”.)
“COOL” flashes in the display dur-
ing charging
This is not a malfunction.
The charging process is in the standby
mode because the battery temperature
is lower than –5  C.
If this occurs, start recharging in a warm place.
When the battery temperature reaches
the specified temperature, “COOL”
goes off and charging starts automati-
cally. (See page 6-1 for more informa-
tion about “Battery charging place”.)

SCOOTER CARE AND STORAGE
EAU37833
Matte color caution NOTICE
ECA15192
Some models are equipped with
matte colored finished parts. Be
sure to consult a Yamaha dealer for
advice on what products to use be-
fore cleaning the vehicle. Using a
brush, harsh chemical products or
cleaning compounds when cleaning
these parts will scratch or damage
their surface. Wax also should not
be applied to any matte colored fin-ished parts.
EAU50832
Care While the open design of a scooter re-
veals the attractiveness of the technol-
ogy, it also makes it more vulnerable.
Rust and corrosion can develop even if
high-quality components are used. Fre-
quent and proper care does not only
comply with the terms of the warranty,
but it will also keep your scooter looking
good, extend its life and optimize its
performance.
Before cleaning1. Make sure that the seat is properly closed before cleaning.
2. Make sure that all caps and covers as well as all electrical couplers
and connectors, are tightly in-
stalled.
3. Remove extremely stubborn dirt, with a degreasing agent and a
brush, but never apply such prod-
ucts onto seals, gaskets and wheel
axles. Always rinse the dirt and de-
greaser off with water. Cleaning
WARNING
EWA15810

Do not wash the vehicle while
charging the battery. This could
cause a fire or electric shock.

Make sure that the seat is prop-
erly closed before washing. If
the seat is not properly closed,
water could splash on the bat-
tery or built-in charger. This
could cause an electric shock or
short circuit.

Do not wash the charging cord
and charging plug. Wipe cleanwith a dry rag.
NOTICE
ECA17122

Avoid using strong acidic wheel
cleaners, especially on spoked
wheels. If such products are
used on hard-to-remove dirt, do
not leave the cleaner on the af-
fected area any longer than in-
structed. Also, thoroughly rinse
the area off with water, immedi-
ately dry it, and then apply a cor-

mended to apply a corrosion pro-
tection spray on all metal,
including chrome- and nickel-plat-
ed, surfaces.
4. Use spray oil as a universal clean- er to remove any remaining dirt.
5. Touch up minor paint damage caused by stones, etc.
6. Wax all painted surfaces.
7. Let the scooter dry completely be- fore storing or covering it.
WARNING
EWA15820
Contaminants on the brakes or tires
can cause loss of control.
Make sure that there is no oil or
wax on the brakes or tires. If
necessary, wash the tires with
warm water and a mild deter-
gent.

Before operating the scooter,
test its braking performanceand cornering behavior.
NOTICE
ECA10800

Apply spray oil and wax spar-
ingly and make sure to wipe off any excess.

Never apply oil or wax to any
rubber and plastic parts, but
treat them with a suitable care
product.

Avoid using abrasive polishing
compounds as they will wearaway the paint.
TIP
Consult a Yamaha dealer for ad-
vice on what products to use.

Washing, rainy weather or humid
climates can cause the headlight
lens to fog. Turning the headlight
on for a short period of time will
help remove the moisture from thelens.
EAU50843
Storage Short-term
Always store your scooter in a cool, dry
place and, if necessary, protect it
against dust with a porous cover. Be
sure the motor is cool before covering
the scooter.NOTICE
ECA17130

Storing the scooter in a poorly
ventilated room or covering it
with a tarp while it is still wet,
will allow water and humidity to
seep in and cause rust, power
unit failure, electric leakage, or
short-circuiting.

To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-cals are stored.
Long-term
