Immobilizer system indicator light
“”
The electrical circuit of the indicator
light can be checked by turning the
key to “ON”. The indicator light
should come on for a few seconds,
and then go off.
If the indicator light does not come on
initially when the key is turned to
“ON”, or if the indicator light remains
on, have a Yamaha dealer check the
electrical circuit.
When the key is turned to “OFF” and
30 seconds have passed, the indica-
tor light will start flashing indicating
the immobilizer system is enabled.
After 24 hours have passed, the indi-
cator light will stop flashing, however
the immobilizer system is still ena-
bled.
The self-diagnosis device also
detects problems in the immobilizer
system circuits. (See 3-8 for an expla-
nation of the self-diagnosis device.)

Be sure to stop the vehicle before
making any setting changes to the
multi-function display. Changing
settings while riding can distract
the operator and increase the risk
of an accident.
The multi-function display is equip-
ped with the following:
a speedometer (which shows the
riding speed)
a digital tachometer (which
shows engine r/min)
an odometer (which shows the
total distance traveled)
two tripmeters (which show the
distance traveled since they were
last set to zero)
a fuel reserve tripmeter (which
shows the distance traveled sin-
ce the bottom segment of the
fuel meter started flashing)

Fuel meter
1. 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 seg-
ments of the fuel meter appear one
after the other and then disappear in
order to test the electrical circuit. The
display segments of the fuel meter
disappear towards “E” (Empty) as the
fuel level decreases. When only one
segment is left near “E” (Empty),
refuel as soon as possible.
TIP
This fuel meter is equipped with a self-
diagnosis system. If the electrical circuit
is defective, all the segments start flas-
hing. If this occurs, have a Yamaha dea-
ler check the electrical circuit.

ABS (for ABS models)
The Yamaha ABS (Anti-lock Brake
System) features a dual electronic
control system, which acts on the
front and rear brakes independently.
The ABS is monitored by an ECU,
which will have recourse to manual
braking if a malfunction occurs.
EWA10090
The ABS performs best on long
braking distances.
On certain (rough or gravel)
roads, the braking distance
may be longer with than wit-
hout the ABS. Therefore,
always keep a sufficient distan-
ce to the vehicle ahead to
match the riding speed.
TIP
When the ABS is activated, the
brakes are operated in the usual
way. A pulsating action may be
felt at the brake lever or brake
pedal, but this does not indicate
a malfunction.

This ABS has a test mode which
allows the owner to experience
the pulsating at the brake lever or
brake pedal when the ABS is
operating. However, special tools
are required, so please consult
your Yamaha dealer when perfor-
ming this test.

tion, the key cannot be removed if the

Make sure that the fuel tank cap is
properly closed after filling fuel.
Leaking fuel is a fire hazard.

Fuel
Make sure there is sufficient gasoline
in the tank.
EWA10881
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 engi-
ne and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the
vicinity 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.
1. Fuel tank filler tube
2. Maximum fuel level
3. Wipe up any spilled fuel imme-
diately. NOTICE: Immediately
wipe off spilled fuel with a cle-
an, dry, soft cloth, since fuel
may deteriorate painted surfa-
ces or plastic parts.

4. Be sure to securely close the fuel
tank cap.

Use only unleaded gasoline. The
use of leaded gasoline will cause
severe damage to internal engine
parts, such as the valves and piston
rings, as well as to the exhaust sys-
tem.
Your Yamaha engine has been desig-
ned to use premium unleaded gasoli-ne with a research octane number of
95 or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand. Use of unleaded fuel will
extend spark plug life and reduce
maintenance costs.

Before operating the motorcycle:
Check the fuel tank breather/over-

cracks or damage, and replace it
if damaged.
Make sure that the end of the fuel

Catalytic converters
This vehicle is equipped with catalytic
converters in the exhaust system.
EWA10862
The exhaust system is hot after
operation. To prevent a fire hazard
or burns:
Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.
Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.
Make sure that the exhaust
system has cooled down befo-
re doing any maintenance
work.
Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up of
heat.
