self-diagnosis is completed, the display
automatically changes to the standby
mode. When in the standby mode,
“PUSH” starts flashing.
Push any of the following buttons to en-
ter the riding mode.

Control buttons
Button 1 “POWER”
Button 2 “SET”
Button 3 “SELECT”
The following operations and settings
are made using these buttons.
Changing from the standby mode
to the riding mode

Switching between the odometer
and the tripmeter

Resetting the tripmeter

Registering or changing the secu-
rity number

Locking and unlocking the security
lock
Speedometer
The speedometer shows the riding
speed.
Tripmeter “Trip”
The tripmeter shows the distance trav- eled since it was last set to zero. To re-
set the tripmeter, push and hold button
3 “SELECT” for a few seconds until
“0.0” is displayed.
Odometer “Odo”
Push button 3 “SELECT” for at least
one second to switch the display to the
odometer.
The odometer shows the total distance
traveled. Use the odometer as a refer-
ence for the intervals between perform-
ing periodic maintenance.
Push button 3 for at least one second to
switch the display to the tripmeter.
Temperature warning display
“HEAT”/“COOL”
The EC-03 is equipped with a tempera-
ture protection function to protect the
battery and control unit.
If a problem is detected, the tripmeter/
odometer display is canceled and
“COOL” or “HEAT” flash.

When the temperature of the bat-
tery or control unit exceeds a spec-
ified temperature, “HEAT” flashes.

When the temperature of the bat-
tery falls below a specified temper-ature, “COOL” flashes.
TIP
When the temperature of the bat-
tery exceeds a specified tempera-
ture, “HEAT” flashes and the
driving power is reduced to limit
the electric output from the battery,
but this is normal.

When the temperature of the bat-
tery falls below a specified temper-
ature, “COOL” flashes and the
driving power is reduced to limit
the electric output from the battery,
but this is normal.

If the vehicle is ridden for an ex-
tended period in high tempera-
tures, “HEAT” may flash and the
riding speed may be reduced.

If the vehicle is ridden after it has
been left in a hot place or under di-
rect sunlight, “HEAT” may flash
and the riding speed may be re-
duced.

If the vehicle is ridden after it has
been left in an excessively cold
place (less than 0
C), “COOL”
may flash and the riding speed
may be reduced.


When the battery level indicator
shows less than two segments, if
the vehicle is exposed to higher
temperatures, “COOL” may flash
and the riding speed may be re-
duced.

When riding on a long uphill
stretch, “HEAT” may flash and the
riding speed may be reduced.

When riding on a long uphill
stretch, the temperature of the
control unit may rise and “HEAT”
may flash. If you ride continually,
the operating status indicator
“RUN” goes off to protect the con-
trol unit and further riding may be
impossible, but this is not a mal-function.
The vehicle can be ridden when the op-
erating status indicator “RUN” appears
in the display, however riding speed
may be reduced. This is due to reduced
electric output from the battery be-
cause of high battery temperature. If the battery level indicator shows less
than two segments, or the electric out-
put from the battery is limited because
of the battery temperature, the riding
power is substantially reduced, but this
is not a malfunction.
When the battery and control unit have
reached their normal operating temper-
ature and the operating status indicator
“RUN” appears, the temperature warn-
ing display automatically changes back
to the tripmeter/odometer display.
If the operating status indicator “RUN”
does not appear, the vehicle cannot be
ridden.Turn the key to “OFF” and allow the
battery and control unit to cool down
before riding again.
TIPWhen the operating status indicator
“RUN” disappears and riding cannot be
continued, the temperature warning
display can be canceled by turning the
key to “OFF” and then back to “ON” af-
ter the battery and control unit havecooled down.

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.)
