3If 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.
TIPThis model is also equipped with a self-
diagnosis device for the fuel level de-
tection circuit. If a problem is detected
in the fuel level detection circuit, the
following cycle will be repeated until
the malfunction is corrected: The fuel
level warning light will flash eight times,
and then go off for 3.0 seconds. If this
occurs, have a Yamaha dealer check
the vehicle.

This warning light comes on if the en-
gine overheats. If this occurs, reduce
the load on the engine immediately. If
message “HI” flashes in the coolant
temperature display, stop the vehicle,
then stop the engine and let the engine
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.

This warning light comes on if a prob-
lem is detected in the electrical circuit
monitoring the engine. If this occurs,
have a Yamaha dealer check the self-
diagnosis system. (See page 3-11 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

Shift timin g in dicator li ght
This indicator light can be set to come
on and go off at the desired engine
speeds and is used to inform the rider
when it is time to shift to the next high-
er gear. 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. (See page 3-12 for a detailed
explanation of the function of this indi-
cator light and on how to set it.)

When the key is turned to “OFF” and
30 seconds have passed, the indicator
light will start flashing indicating the im-
mobilizer system is enabled. After 24
hours have passed, the indicator light
will stop flashing, however the immobi-
lizer system is still enabled.
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.
The self-diagnosis device also detects
problems in the immobilizer system
circuits. (See page 3-11 for an expla-
nation of the self-diagnosis device.)

Self-d iagnosis device
This model is equipped with a self-di-
agnosis device for various electrical
circuits. If a problem is detected in any of those
circuits, the engine trouble warning
light will come on and the right display
will indicate an error code.
If the right display indicates any error
codes, note the code number, and
then have a Yamaha dealer check the
vehicle.
The self-diagnosis device also detects
problems in the immobilizer system
circuits.
If a problem is detected in the immobi-
lizer system circuits, the immobilizer
system indicator light will flash and the
right display will indicate an error code.
TIPIf the right display indicates error code
52, this could be caused by transpon-
der interference. If this error code ap-
pears, try the following.1. Use the code re-registering key to
start the engine.TIPMake sure there are no other immobi-
lizer keys close to the main switch, and
do not keep more than one immobilizer
key on the same key ring! Immobilizer system keys may cause signal interfer-
ence, which may prevent the engine
from starting.
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
key and both standard keys to a
Yamaha dealer and have the stan-
dard keys re-registered.NOTICE
