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
Yamaha dealer check the vehicle.

“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-

rosion protection spray.

Improper cleaning can damage
plastic parts such as cowlings,
panels, windshields, headlight
lenses, meter lenses, etc. Use
only a soft, clean cloth or
sponge with water to clean plas-
tic. However, if the plastic parts
cannot be thoroughly cleaned
with water, diluted mild deter-
gent with water may be used. Be
sure to rinse off any detergent
residue using plenty of water, as
it is harmful to plastic parts.

Do not use any harsh chemical
products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abrasive
cleaning products, solvent or
thinner, gasoline, rust removers
or inhibitors, brake fluid, anti-
freeze or electrolyte.

Do not use high-pressure wash-
ers or steam-jet cleaners since
they cause water seepage and
deterioration in the following ar-
eas: seals (of wheel and swing-
arm bearings, fork and brakes),electric components (couplers,
connectors, instruments, accel-
erator grip, switches and lights),
breather hoses and vents.

For scooters equipped with a
windshield: Do not use strong
cleaners or hard sponges as
they will cause dulling or
scratching. Some cleaning com-
pounds for plastic may leave
scratches on the windshield.
Test the product on a small hid-
den part of the windshield to
make sure that it does not leave
any marks. If the windshield is
scratched, use a quality plastic
polishing compound afterwashing.
After normal use
Remove dirt with warm water, a mild
detergent, and a soft, clean sponge,
and then rinse thoroughly with clean
water. Use a toothbrush or bottlebrush
for hard-to-reach areas. Stubborn dirt
and insects will come off more easily if
the area is covered with a wet cloth for
a few minutes before cleaning. After riding in the rain, near the sea or
on salt-sprayed roadsSince sea salt or salt sprayed on the
roads during winter are extremely cor-
rosive in combination with water, carry
out the following steps after each ride in
the rain, near the sea or on
salt-sprayed roads.TIPSalt sprayed on roads in the winter mayremain well into spring.
1. Clean the scooter with cold water and a mild detergent after the mo-
tor has cooled down. NOTICE: Do
not use warm water since it in-
creases the corrosive action of
the salt.
[ECA10791]

2. Apply a corrosion protection spray on all metal, including chrome- and
nickel-plated, surfaces to prevent
corrosion.
After cleaning 1. Dry the scooter with a chamois or an absorbing cloth.
2. Use a chrome polish to shine chrome, aluminum and stain-
less-steel parts.

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
