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.

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.
TIPThe 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.

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.
