keys away from the main switch
as they may cause signal inter-
ference.
EAU10473
Main switch/steering lockThe main switch/steering lock controls
the ignition and lighting systems, and is
used to lock the steering. The various
positions are described below.TIPBe 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.
EAU34122
ON
All electrical circuits are supplied with
power; the meter lighting, taillight, li-
cense plate light and auxiliary lights
come on, and the engine can be start-
ed. The key cannot be removed.TIPThe headlights come on automatically
when the engine is started and stay on

EAU10662
OFF
All electrical systems are off. The key
can be removed.
WARNING
EWA10062
Never turn the key to “OFF” or
“LOCK” while the vehicle is moving.
Otherwise the electrical systems will
be switched off, which may result in
loss of control or an accident.

Fuel tank capTo open the fuel tank cap
1. Insert the key into the lock and
turn it counterclockwise. The lock
will be released and the lid can be
pulled open.
2. To remove the fuel tank cap, turn
it counterclockwise and then pull it
off.
To close the fuel tank cap
1. Place the fuel tank cap onto the
fuel tank opening and turn the fuel
tank cap clockwise.
WARNING
EWA11092
Make sure that the fuel tank cap is
properly closed after filling fuel.
Leaking fuel is a fire hazard.2. Close the lid, turn the key clock-
wise to the original position, and
then remove it.
EAU13222
FuelMake sure there is sufficient gasoline in
the tank.
WARNING
EWA10882
Gasoline and gasoline vapors are
extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, follow
these instructions.1. Before refueling, turn off the en-
gine and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the vi-
cinity of sparks, open flames, or
other sources of ignition such as
the pilot lights of water heaters
and clothes dryers.
2. Do not overfill the fuel tank. When
refueling, be sure to insert the
pump nozzle into the fuel tank filler
hole. Stop filling when the fuel
reaches the bottom of the filler
tube. Because fuel expands when
it heats up, heat from the engine or
the sun can cause fuel to spill out
of the fuel tank.

adjusting ring with the position in-
dicator on the shock absorber.
Use the spring preload adjusting
tool included in the owner’s tool
kit to make this adjustment.
EAU15306
SidestandThe sidestand is located on the left
side of the frame. Raise the sidestand
or lower it with your foot while holding
the vehicle upright.TIPThe built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain situa-
tions. (See the following section for an
explanation of the ignition circuit cut-
off system.)
WARNING
EWA10242
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 control.
Yamaha’s ignition circuit cut-off
system has been designed to assist
the operator in fulfilling the respon-
sibility of raising the sidestand be-
fore starting off. Therefore, check
this system regularly and have a
Yamaha dealer repair it if it does not
function properly.

Ignition circuit cut-off systemThe ignition circuit cut-off system
(comprising the sidestand switch and
brake light switches) has the following
functions.
It prevents starting when the side-
stand is up, but neither brake is
applied.
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 accord-
ing to the following procedure.

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.
WARNING

Failure to familiarize yourself with
the controls can lead to loss of con-
trol, which could cause an accident
or injury.

TIPThis model is equipped with a lean an-
gle sensor to stop the engine in case of
a turnover. In this case, the multi-func-
tion 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 pre-
vent the engine from starting even
though the engine will crank when
pushing the start switch.
