3taken place), the main switch can be
turned while the smart key system indi-
cator light is on (approximately 4 sec-
onds).
WARNING
EWA18720
Never turn the main switch to
“OFF”, “ ”, or “OPEN” while the ve-
hicle is moving. Otherwise the elec-
trical systems will be switched off,
which may result in loss of control or
an accident.TIPDo not push the main switch knob re-
peatedly or turn the main switch back
and forth excessively (beyond normal
use). To protect the main switch from
damage, the smart key system will
temporarily disable, and the smart key
system indicator light will flash. If this
occurs, wait until the indicator light
stops flashing, and then operate the
main switch.The main switch positions are de-
scribed below.
EAU76502
ON
All electrical circuits are supplied with
power, and the engine can be started.
To turn the vehicle power on1. Turn the smart key on and bring it
within operating range.
2. Push the main switch knob and
the smart key indicator light will
come on for approximately 4 sec-
onds.
3. While the smart key system indi-
cator light is on, turn the main
switch to “ON”. All of the turn sig-
nal lights will flash twice and the
vehicle power will turn on.
TIPIf the vehicle battery voltage is
low, the turn signal lights will not
flash.
See “Emergency mode” on page
9-38 for information on turning the
vehicle power on without the
smart key.
EAU76511

All electrical systems are off.
To turn the vehicle power off1. With the smart key turned on and
within operating range, turn the
main switch to “OFF”.

Each indicator light will flash when its
corresponding turn signal lights are
flashing.

High beam indicator light “ ”
This indicator light comes on when the
high beam of the headlight is switched
on.
EAU88711
Malfunction indicator light
(MIL) “ ”
This light comes on or flashes if a prob-
lem is detected in the engine or other
vehicle control system. If this occurs,
have a Yamaha dealer check the on-
board diagnostic system. The electri-
cal circuit of the warning light can be
checked by vehicle power on. The light
should come on for a few seconds,
and then go off. If the light does not
come on initially when the vehicle pow-
er on, or if the light remains on, have a
Yamaha dealer check the vehicle.
NOTICE
ECA26820
If the MIL starts flashing, reduce en-
gine speed to prevent exhaust sys-
tem damage.TIPThe engine is sensitively controlled for
the on-board diagnostic system to de-
tect deterioration and malfunction of
the emission control system. Due to
this specification, the MIL may come
on or flash for vehicle modifications,
lack of maintenance, or excessive or
improper use of the vehicle. To prevent
this, observe these precautions.
Do not attempt to modify the soft-
ware of the engine control unit.
Do not add any electrical acces-
sories that interfere with engine
control.
Do not use aftermarket accesso-
ries or parts such as suspension,
spark plugs, injectors, exhaust
system, etc.
Do not change drivetrain specifi-
cations (chain, sprockets, wheels,
tires, etc.).

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. 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.3. Wipe up any spilled fuel immedi-
ately. NOTICE: Immediately
wipe off spilled fuel with a clean,
dry, soft cloth, since fuel may
deteriorate painted surfaces or
plastic parts.
[ECA10072]
4. Be sure to securely close the fuel
tank cap.
WARNING
EWA15152
Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gasoline
by mouth. If you should swallow
some gasoline or inhale a lot of gas-
oline vapor, or get some gasoline in
your eyes, see your doctor immedi-ately. If gasoline spills on your skin,
wash with soap and water. If gaso-
line spills on your clothing, change
your clothes.
EAU86072
Your Yamaha engine was designed to
use unleaded gasoline with a research
octane number of 90 or higher. If en-
gine knocking or pinging occurs, use a
gasoline of a different brand or higher
octane rating.TIPThis mark identifies the recom-
mended fuel for this vehicle as
specified by European regulation
(EN228).

Operation and important riding points

EAU16782
Acceleration and decelerationThe speed can be adjusted by opening
and closing the throttle. To increase
the speed, turn the throttle grip in di-
rection (a). To reduce the speed, turn
the throttle grip in direction (b).
EAU60650
Braking
WARNING
EWA17790
Avoid braking hard or suddenly
(especially when leaning over to
one side), otherwise the vehicle
may skid or overturn.
Railroad crossings, streetcar
rails, iron plates on road con-
struction sites, and manhole
covers become extremely slip-
pery when wet. Therefore, slow
down when approaching such
areas and cross them with cau-
tion.
Keep in mind that braking on a
wet road is much more difficult.
Ride slowly down a hill, as brak-
ing downhill can be very diffi-
cult.1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually in-
creasing the pressure.
EAU16821
Tips for reducing fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
Avoid high engine speeds during
acceleration.
Avoid high engine speeds with no
load on the engine.
Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at traf-
fic lights or at railroad crossings).

TroubleshootingAlthough Yamaha vehicles receive a
thorough inspection before shipment
from the factory, trouble may occur
during 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 vehicle re-
quire any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the vehicle prop-
erly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills.
WARNING
EWA15142
When checking the fuel system, do
not smoke, and make sure there are
no open flames or sparks in the ar-
ea, including pilot lights from waterheaters or furnaces. Gasoline or
gasoline vapors can ignite or ex-
plode, causing severe injury or prop-
erty damage.
EAU76551
Smart key system troubleshooting
Please check the following items when
the smart key system does not work.
Is the smart key turned on? (See
page 3-4.)
Is the smart key battery dis-
charged? (See page 3-6.)
Is the smart key battery installed
correctly? (See page 3-6.)
Is the smart key being used in a lo-
cation with strong radio waves or
other electromagnetic noise? (See
page 3-1.)
Are you using the smart key that is
registered to the vehicle?
Is the vehicle battery discharged?
When the vehicle battery is dis-
charged, the smart key system will
not operate. Please have the vehi-
cle battery charged or replaced.
