Coolant temperature warning light
“”
This warning light comes on if the
engine overheats. If this occurs, stop
the engine immediately and allow the
engine to cool.
The electrical circuit of the warning
light can be checked by turning the
key to “ON”. The warning light should
come on for a few seconds, and then
go off.
If the warning light does not come on
initially when the key is turned to
“ON”, or if the warning light remains
on, have a Yamaha dealer check the
electrical circuit.
ECA10021
Do not continue to operate the
engine if it is overheating.
TIP
For radiator-fan-equipped vehi-
cles, the radiator fan(s) automati-
cally switch on or off according to
the coolant temperature in the
radiator.
If the engine overheats, see page
6-40 for further instructions.
EAU11534
Engine trouble warning light “ ”
This warning light comes on or flas-
hes if a problem is detected in the
electrical circuit monitoring the engi-
ne. If this occurs, have a Yamaha dea-
ler check the self-diagnosis system.
(See page 3-8 for an explanation of
the self-diagnosis device.)
The electrical circuit of the warning
light can be checked by turning the
key to “ON”. The warning light should
come on for a few seconds, and then
go off.
If the warning light does not come on
initially when the key is turned to
“ON”, or if the warning light remains
on, have a Yamaha dealer check the
electrical circuit.
EAU11545
ABS warning light “ ” (for ABS
models)
If this warning light comes on or flas-
hes while riding, the ABS may not
work correctly. If this occurs, have aYamaha dealer check the system as
soon as possible. (See page 3-12).
EWA10081
If the ABS warning light comes on
or flashes while riding, the brake
system reverts to conventional bra-
king. Therefore, be careful not to
cause the wheels to lock during
emergency braking. If the warning
light comes on or flashes while
riding, have a Yamaha dealer check
the brake system as soon as possi-
ble.
The electrical circuit of the warning
light can be checked by turning the
key to “ON”. The warning light should
come on for a few seconds, and then
go off.
If the warning light does not come on
initially when the key is turned to
“ON”, or if the warning light remains
on, have a Yamaha dealer check the
electrical circuit.

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)
a clock

Be sure to turn the key to “ON”
before using the “SELECT” and
“RESET” buttons.

TIP
The clock always shows the time
regardless of the main switch posi-
tion.
To set the clock:
1. Push the “SELECT” button for at
least four seconds.
2. When the hour digits start flas-
hing, push the “RESET” button to
set the hours.
3. Push the “SELECT” button, and
the minute digits start flashing.
4. Push the “RESET” button to set
the minutes.5. Push the “SELECT” button and
then release it to start the clock.
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.

(for ABS models)
If any of the ABS electrical circuits are
defective, the ABS warning light will
come on. If this occurs, have a Yama-
ha dealer check the vehicle.
This model is also equipped with a
self-diagnosis device for the immobi-
lizer system.
If any of the immobilizer system cir-
cuits are defective, the immobilizer
system indicator light starts flashing.
If this occurs, have a Yamaha dealer
check the vehicle.
TIP
If 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-registe-
ring key and both standard keys
to a Yamaha dealer and have the
standard keys re-registered.

indicator lights should come on for
a few seconds, then go off.
Neutral indicator light
Turn signal indicator light
High beam indicator light
Engine trouble warning light

light
Immobilizer system indicator
light
ABS warning light (for ABS
model)
If a warning or indicator light does
not go off, see page 3-4 for the
corresponding warning and indica-
tor light circuit check.
2. Shift the transmission into the
neutral position.
TIP
When the transmission is in the neu-
tral position, the neutral indicator light
should be on, otherwise have a
Yamaha dealer check the electrical
circuit.
3. Start the engine by pushing the
start switch. NOTICE: For maxi-
mum engine life, never accele-
rate hard when the engine is
cold!
[ECA11041]
TIP
If the engine fails to start, release the
start switch, wait a few seconds, and
then try again. Each starting attempt
should be as short as possible to pre-
serve the battery. Do not crank the
engine more than 10 seconds on any
one attempt.
TIP
The engine is warm when it quickly
responds to the throttle.

Shifting
1. Shift pedal
2. Neutral position
Shifting gears lets you control the
amount of engine power available for
starting off, accelerating, climbing
hills, etc.
The gear positions are shown in the
illustration.
TIP
To shift the transmission into the neu-
tral position, press the shift pedal
down repeatedly until it reaches the
end of its travel, and then slightly rai-
se it.

2. Remove the spark plug as
shown, with the spark plug
wrench included in the owner’s
tool kit.
To check the spark plug
1. Check that the porcelain insula-
tor around the center electrode of
the spark plug is a medium-to-
light tan (the ideal color when the
vehicle is ridden normally).
TIP
If the spark plug shows a distinctly
different color, the engine could be
operating improperly. Do not attempt
to diagnose such problems yourself.
Instead, have a Yamaha dealer check
the vehicle.
2. Check the spark plug for electro-
de erosion and excessive carbon
or other deposits, and replace it if
necessary.3. Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to spe-
cification.
1. Spark plug gap
To install the spark plug
1. Clean the surface of the spark
plug gasket and its mating surfa-
ce, and then wipe off any grime
from the spark plug threads.
2. Install the spark plug with the
spark plug wrench, and then
tighten it to the specified torque.
TIP
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is
1/4–1/2 turn past finger tight. Howe-
ver, the spark plug should be tighte-
ned to the specified torque as soon
as possible.
3. Install the spark plug cap.
Tightening torque:
Spark plug:
12.5 Nm (1.25 m·kgf, 9.0 ft·lbf)
Spark plug gap:
0.7–0.8 mm (0.028–0.031 in)
