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.

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.

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

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.

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-
