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


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.
