“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

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-

893. To prevent corrosion, it is recom-
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
NOTICE

Charge the battery if the level
drops to the last segment. In or-

der to extend the battery life, it is
recommended to charge the
battery until the battery level in-
dicator reaches a maximum of
2–3 segments. A lower or higher
charge is not recommended.

Make sure that the amount of
charge remaining in the battery
does not fall below 20% (less
than the last segment of the bat-
tery level indicator). If stored un-
der this condition for a long
period of time, the battery can
be damaged and may need to be
replaced depending on how low
the capacity is.

Once the battery is completely
depleted, it cannot be re-
charged.

After long-term storage, be sure
to recharge the battery before
using the vehicle. (It may takelonger to charge than usual.)
Before storing your scooter for several
months: 1. Follow all the instructions in the “Care” section of this chapter.
2. Lubricate all control cables and the pivoting points of all levers as well
as the centerstand.
3. Check and, if necessary, correct the tire air pressure, and then lift
the scooter so that both of its
wheels are off the ground. Alterna-
tively, turn the wheels a little every
month in order to prevent the tires
from becoming degraded in one
spot.
TIPMake any necessary repairs beforestoring the scooter.
