Fuel meter
With the key in the “ON” position, the
fuel meter indicates the amount of fuel
in the fuel tank. When the key is turned
to “ON”, all of the display segments of
the fuel meter appear one after the oth-
er and then disappear in order to test
the electrical circuit. The display seg-
ments of the fuel meter disappear to-
wards “E” (Empty) as the fuel level
decreases. When only one segment is
left near “E” (Empty), refuel as soon as
possible.
TIPThis fuel meter is equipped with a self-
diagnosis system. If the electrical cir-
cuit is defective, all the segments start
flashing. If this occurs, have a Yamaha
dealer check the electrical circuit.Self-diagnosis devices
This model is equipped with a self-di-
agnosis device for various electrical
circuits.
If any engine electrical circuits are de-
fective, the engine trouble warning light
starts flashing. If this occurs, have a
Yamaha dealer check the vehicle.(for ABS models)
If any of the ABS electrical circuits are
defective, the ABS warning light will
come on. If this occurs, have a Yamaha
dealer check the vehicle.
This model is also equipped with a self-
diagnosis device for the immobilizer
system.
If any of the immobilizer system circuits
are defective, the immobilizer system
indicator light starts flashing. If this oc-
curs, have a Yamaha dealer check the
vehicle.
TIPIf the indicator light slowly flashes five
times, and then quickly flashes two
times repeatedly, this error could be
caused by transponder interference. If
this occurs, try the following.1. Use the code re-registering key to
start the engine.
2. If the engine starts, turn it off, and
try starting the engine with the
standard keys.
3. If one or both of the standard keys
do not start the engine, take the
vehicle, the code re-registering

Clutch leverThe clutch lever is located at the left
handlebar grip. To disengage the
clutch, pull the lever toward the han-
dlebar grip. To engage the clutch, re-
lease the lever. The lever should be
pulled rapidly and released slowly for
smooth clutch operation.
The clutch lever is equipped with a
clutch switch, which is part of the igni-
tion circuit cut-off system. (See page

ABS (for ABS models)The Yamaha ABS (Anti-lock Brake
System) features a dual electronic con-
trol system, which acts on the front and
rear brakes independently.
Operate the brakes with ABS as you
would conventional brakes. If the ABS
is activated, a pulsating sensation may
be felt at the brake lever or brake ped-
al. In this situation, continue to apply
the brakes and let the ABS work; do
not “pump” the brakes as this will re-
duce braking effectiveness.
WARNING
EWA16051
Always keep a sufficient distance
from the vehicle ahead to match the
riding speed even with ABS.
The ABS performs best with
long braking distances.
On certain surfaces, such as
rough or gravel roads, the brak-
ing distance may be longer with
the ABS than without.The ABS is monitored by an ECU,
which will revert the system to conven-
tional braking if a malfunction occurs.
TIPThe ABS performs a self-diagno-
sis test each time the vehicle first
starts off after the key is turned to
“ON” and the vehicle has traveled
at a speed of 10 km/h (6 mi/h) or
higher. During this test, a “click-
ing” noise can be heard from un-
der the seat, and if the brake lever
or brake pedal is even slightly ap-
plied, a vibration can be felt at the
lever and pedal, but these do not
indicate a malfunction.
This ABS has a test mode which
allows the owner to experience
the pulsation at the brake lever or
brake pedal when the ABS is op-
erating. However, special tools are
required, so please consult your
Yamaha dealer.NOTICE
ECA16121
Keep any type of magnets (including
magnetic pick-up tools, magnetic
screwdrivers, etc.) away from the
front and rear wheel hubs, otherwise
the magnetic rotors equipped in thewheel hubs may be damaged, re-
sulting in improper performance of
the ABS system.

Fuel tank capTo open the fuel tank cap
Open the fuel tank cap lock cover, in-
sert the key into the lock, and then turn
it 1/4 turn clockwise. The lock will be
released and the fuel tank cap can be
opened.
To close the fuel tank cap
1. Push the fuel tank cap into posi-
tion with the key inserted in the
lock.
2. Turn the key counterclockwise to
the original position, remove it,
and then close the lock cover.
TIPThe fuel tank cap cannot be closed un-
less the key is in the lock. In addition,
the key cannot be removed if the cap is
not properly closed and locked.
WARNING
EWA11092
Make sure that the fuel tank cap is
properly closed after filling fuel.
Leaking fuel is a fire hazard.
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.

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

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.

Starting the engineIn order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:
The transmission is in the neutral
position.
The transmission is in gear with
the clutch lever pulled and the
sidestand up.
WARNING
EWA10291
Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure
described on page 3-19.
Never ride with the sidestand
down.1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “ ”.NOTICE
