High beam indicator light “”
This indicator light comes on when the
high beam of the headlight is switched
on.
EAU11361
Fuel level warning light “”
This warning light comes on when the
fuel level drops below approximately
5.0 L (1.32 US gal) (1.10 Imp.gal).
When this occurs, refuel as soon as
possible.
The electrical circuit of the warning light
can be checked by turning the key to
“ON”.
If the warning light does not come on
for a few seconds, and then go off,
have a Yamaha dealer check the elec-
trical circuit.NOTE:This model is also equipped with a self-
diagnosis device for the fuel level de-
tection circuit. If the fuel level detection
circuit is defective, the following cycle
will be repeated until the malfunction is
corrected: The fuel level warning lightwill flash eight times, and then go off for
3.0 seconds. If this occurs, have a
Yamaha dealer check the vehicle.
EAU11440
Coolant temperature warning light
“”
This warning light comes on when the
engine overheats. When 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”.
If the warning light does not come on
for a few seconds, then go off, have a
Yamaha dealer check the electrical cir-
cuit.CAUTION:
ECA10020
Do not operate the engine if it isoverheated.
EAU11530
Engine trouble warning light “”
This warning light comes on or flashes
when an electrical circuit monitoring the
engine is defective. When this occurs,
have a Yamaha dealer check the self-diagnosis system. (See page 3-5 for an
explanation of the self-diagnosis de-
vice.)
The electrical circuit of the warning light
can be checked by turning the key to
“ON”. If the warning light does not come
on for a few seconds, then go off, have
a Yamaha dealer check the electrical
circuit.
EAU26873
Immobilizer system indicator light
“”
The electrical circuit of the indicator
light can be checked by turning the key
to “ON”.
If the indicator light does not come on
for a few seconds, then go off, have a
Yamaha dealer check the electrical cir-
cuit.
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.

EAU15950
WARNING
EWA10270
Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer re-
garding any control or function
that you do not thoroughly un-
derstand.
Never start the engine or oper-
ate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of con-
sciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.
Before starting out, make sure
that the sidestand is up. If the
sidestand is not raised com-
pletely, it could contact the
ground and distract the opera-
tor, resulting in a possible lossof control.
EAUM1670
Starting the engine In 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 sid-
estand up.WARNING
EWA10290
Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure
described on page 3-15.
Never ride with the sidestanddown.
1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “”.
CAUTION:
ECAM1030
The following warning lights and in-
dicator light should come on for a
few seconds, then go off.
Fuel level warning light
Coolant temperature warning

If a warning or indicator light does
not go off, see page 3-3 for the corre-
sponding warning and indicator
light circuit check.
2. Shift the transmission into the neu-
tral position.NOTE:When the transmission is in the neutral
position, the neutral indicator light
should be on, otherwise have a
Yamaha dealer check the electrical cir-cuit.
3. Start the engine by pushing the
start switch.NOTE: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-

6 addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.
Make sure that no foreign mate-rial enters the crankcase.
12. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
13. Turn the engine off, and then
check the oil level and correct it if
necessary.
EAU20070
Coolant The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAUM1722
To check the coolant level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.NOTE:
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to theside can result in a false reading.
2. Check the coolant level in the cool-
ant reservoir.
NOTE:The coolant should be between theminimum and maximum level marks.3. If the coolant is at or below the
minimum level mark, remove cowl-
ing B (See page 6-5.), and then
open the reservoir cap.
4. Add coolant to the maximum level
mark, and then close the reservoir
cap.
1. Coolant reservoir
2. Maximum level mark
3. Minimum level mark
Coolant reservoir capacity (up to the
maximum level mark):
0.25 L (0.26 US qt) (0.22 Imp.qt)

CAUTION:
ECA10471
If coolant is not available, use
distilled water or soft tap water
instead. Do not use hard water
or salt water since it is harmful
to the engine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the cooling system will not
be protected against frost and
corrosion.
If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possible,
otherwise the effectiveness ofthe coolant will be reduced.WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.
5. Install the cowling.
NOTE:
The radiator fan is automatically
switched on or off according to the
coolant temperature in the radia-
tor.
If the engine overheats, see page6-40 for further instructions.
EAUM1802
To change the coolant
1. Place the vehicle on a level sur-
face and let the engine cool if nec-
essary.
2. Remove the seat and panel B.
(See pages 3-12 and 6-5.)
3. Remove cowling B. (See page
6-5.)
4. Place a container under the engine
to collect the used coolant.
5. Loosen the radiator cap retainer
screw.
6. Remove the radiator cap and cool-
ant reservoir cap.
WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.7. Remove the coolant reservoir
bolts, and then turn the coolant
reservoir upside down to empty it.
8. Install the coolant reservoir by
placing it in the original position,
then installing the bolts.
