If the warning light does not come on
for a few seconds, then go off, have a
Yamaha dealer check the electrical cir-
cuit.NOTE:

Even if the oil level is sufficient, the
warning light may flicker when
riding on a slope or during sudden
acceleration or deceleration, but
this is not a malfunction.


This model is also equipped with a
self-diagnosis device for the oil
level detection circuit. If the oil lev-
el detection circuit is defective, the
following cycle will be repeated un-
til the malfunction is corrected: The
oil level warning light will flash ten
times, then go off for 2.5 seconds.
If this occurs, have a Yamahadealer check the vehicle.

Do not operate the engine if it isoverheated.Air intake temperature display
The air intake temperature display indi-
cates the temperature of the air drawn
into the air filter case. Push the “RE-
SET” button to switch the coolant tem-
perature display to the air intake
temperature display.
NOTE:

Even if the air intake temperature
is set to be displayed, the coolant
temperature warning light comes
on when the engine overheats.


When the key is turned to “ON”,
the coolant temperature is auto-
matically displayed, even if the air
intake temperature was displayed
prior to turning the key to “OFF”.


When the air intake temperature
display is selected, “A” is displayedbefore the temperature.
Self-diagnosis devices
This model is equipped with a self-diag-
nosis device for various electrical cir-
cuits.
If any of those circuits are defective, the

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.
EAU33011
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 3-26.


Never ride with the sidestanddown.
1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “”.
CAUTION:
ECA11730
The following warning lights and in-
dicator light should come on for a
few seconds, then go off.

light
If a warning or indicator light does
not go off, see page 3-4 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-

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.
EAU42990
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 6-6.)
4. Remove the reservoir cap, add
coolant to the maximum level
mark, and then install the reservoir
cap.
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.
