EAU10471
Main switch/steering lock
The main switch/steering lock controls
the ignition and lighting systems, and is
used to lock the steering.
NOTE:

Be sure to use the standard key (black
bow) for regular use of the vehicle. To
minimize the risk of losing the code
re-registering key (red bow), keep it in a
safe place and only use it for code
re-registering.
EAU10560
ON
All electrical circuits are supplied with
power; the meter lighting, taillight, li-
cense plate light and auxiliary light
come on, and the engine can be start-ed. The key cannot be removed.
NOTE:

The headlight comes on automatically
when the engine is started and stays on
until the key is turned to “OFF” or the
sidestand is moved down.
EAU10660
OFF
All electrical systems are off. The key
can be removed.
EAU10680

Sidestand
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.
NOTE:

The built-in sidestand switch is part of
the ignition circuit cut-off system, which
cuts the ignition in certain situations.
(See further down for an explanation of
the ignition circuit cut-off system.)
WARNING

EWA10240
The vehicle must not be ridden with
the sidestand down, or if the side-
stand 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 con-
trol. Yamaha’s ignition circuit
cut-off system has been designed
to assist the operator in fulfilling
the responsibility of raising the sid-
estand before starting off. There-fore, check this system regularly
as described below and have a
Yamaha dealer repair it if it does
not function properly.
EAU15371
Ignition circuit cut-off system
The ignition circuit cut-off system (com-
prising the sidestand switch and brake
light switches) has the following func-
tions.

It prevents starting when the side-
stand is up, but neither brake is ap-
plied.

It prevents starting when either
brake is applied, but the sidestand
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.
WARNING

EWA10250
If a malfunction is noted, have a
Yamaha dealer check the system be-
fore riding.

WARNING

EWA11250

Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer re-
garding any control or function
that you do not thoroughly un-
derstand.

Never start the engine or oper-
ate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of con-
sciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.

For safety, always start the en-
gine with the centerstand down.

When the centerstand is down
and the engine is idling, keep
your hands and feet away from
the rear wheel.
EAU27060
Starting the engine
CAUTION:

ECA10250
See page 5-4 for engine break-in in-
structions prior to operating the ve-
hicle for the first time.
In order for the ignition circuit cut-off
system to enable starting, the side-
stand must be up.
WARNING

EWA10290

Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure
described on page 3-16.

Never ride with the sidestand
down.
1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “ ”.
2. Close the throttle completely.
3. Start the engine by pushing the
start switch while applying the front
or rear brake.
NOTE:

If the engine does not start, release the
start switch, wait a few seconds, and
then try again. Each starting attempt
should be as short as possible to pre-
serve the battery. Do not crank the en-
gine more than 10 seconds on any one
attempt. If the engine does not start, try
with the throttle open 1/8 turn.
CAUTION:

ECA11040
For maximum engine life, never ac-
celerate hard when the engine is
cold!

the electrical system and possibly a
fire.

and the bulb life will be adversely af-
fected. Thoroughly clean off any dirt

EAU25880
Troubleshooting
Although Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur dur-
ing operation. Any problem in the fuel,
compression, or ignition systems, for
example, can cause poor starting and
loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your-
self. However, should your scooter re-
quire any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the scooter prop-
erly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look like
Yamaha parts, but they are often inferi-
or, have a shorter service life and can
lead to expensive repair bills.
1. Do not touch the glass part of the bulb.
