Sidestand
1. Sidestand switch
The sidestand is located on the left
side of the frame. Raise the sidestand
or lower it with your foot while holding
the vehicle upright.
TIP
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain
situations. (See page 3-22 for an
explanation of the ignition circuit cut-
off system.)
EWA10240
The vehicle must not be ridden with
the sidestand down, or if the sides-
tand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control. Yama-
ha’s ignition circuit cut-off system
has been designed to assist the
operator in fulfilling the responsibi-
lity of raising the sidestand before
starting off. Therefore, check this
system regularly as described
below and have a Yamaha dealer
repair it if it does not function pro-
perly.
EAU45051
Ignition circuit cut-off
system
The ignition circuit cut-off system
(comprising the sidestand switch and
brake light switches) has the following
functions.
It prevents starting when the
sidestand is up, but neither brake
is applied.
It prevents starting when either
brake is applied, but the sides-
tand is still down.
It cuts the running engine when
the sidestand is moved down.
Periodically check the operation of
the ignition circuit cut-off system
according to the following procedure.

EAU15951
Read the Owner’s Manual carefully to
become familiar with all controls. If
there is a control or function you do
not understand, ask your Yamaha
dealer.
EWA10271
Failure to familiarize yourself with
the controls can lead to loss of
control, which could cause an acci-
dent or injury.

TIP
This model is equipped with a lean
angle sensor to stop the engine in
case of a turnover. In this case, the
multi-function display indicates error
code 30, but this is not a malfunction.
Turn the key to “OFF” and then to
“ON” to clear the error code. Failing
to do so will prevent the engine from
starting even though the engine will
crank when pushing the start switch.

See page 5-4 for engine break-in
instructions prior to operating the
vehicle for the first time.
In order for the ignition circuit cut-off
system to enable starting, the sides-
tand must be up.
See page 3-22 for more information.
1. Turn the key to “ON”.

sure that no foreign material
enters the final transmission
case. Make sure that no oil
gets on the tire or wheel.
[EWA11311]
8. Install the final transmission oil
filler cap and its new O-ring, and
then tighten the oil filler cap.
9. Check the final transmission case
for oil leakage. If oil is leaking,
check for the cause.

Coolant
The coolant level should be checked
before each ride. In addition, the coo-
lant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAUS1670
To check the coolant level
1. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion.
TIP
The coolant level must be chec-
ked on a cold engine since the
level varies with engine tempera-
ture.
Make sure that the vehicle is
positioned straight up when
checking the coolant level. A
slight tilt to the side can result in
a false reading.
2. Check the coolant level through
the check window.
TIP
The coolant should be between the
minimum and maximum level marks.
1. Maximum level mark
2. Minimum level mark
3. Coolant level check window
3. If the coolant is at or below the
minimum level mark, lift up the
right floorboard mat as shown.

Replacing the fuses
The fuse box, which contains the
fuses for the individual circuits, is
located behind cowling A. (See page
6-8).
TIP
The main fuse, which is in a different
and hard-to-reach location, must be
replaced by a Yamaha dealer.
If a fuse for the individual circuits is
blown, replace it as follows.
1. Turn the key to “OFF” and turn off
the electrical circuit in question.
2. Remove the blown fuse, and then
install a new fuse of the specified
amperage. WARNING! Do not
use a fuse of a higher ampera-
ge rating than recommended
to avoid causing extensive
damage to the electrical sys-
tem and possibly a fire.
[EWA15131]
TIP
Fuse tongs and a bag containing spa-
re fuses are included in the owner’s
tool kit. Use the tongs to remove and
install a fuse.

When checking the fuel system, do
not smoke, and make sure there
are no open flames or sparks in the
area, including pilot lights from
water heaters or furnaces. Gasoli-
ne or gasoline vapors can ignite or
explode, causing severe injury or
property damage.

4. Use spray oil as a universal clea-
ner 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
before storing or covering it.
EWA10942
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, clean the brake
discs and brake linings with a
regular brake disc cleaner or
acetone, and wash the tires
with warm water and a mild
detergent.
Before operating the scooter
test its braking performance
and cornering behavior.
ECA10800
Apply spray oil and wax spa-
ringly and make sure to wipeoff 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 wear
away the paint.
TIP
Consult a Yamaha dealer for
advice 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
the lens.
EAU36561
Storage
Short-term
Always store your scooter in a cool,
dry place and, if necessary, protect it
against dust with a porous cover.
ECA10820
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.
To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-
cals are stored.
Long-term
Before storing your scooter for seve-
ral months:
1. Follow all the instructions in the
“Care” section of this chapter.
2. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
