TIP

For radiator-fan-equipped vehi-
cles, the radiator fan(s) automati-
cally switch on or off according to
the coolant temperature in the ra-
diator.


If the engine overheats, see page6-37 for further instructions.

Engine trouble warning light“”
This warning light flashes or stays on if
an electrical circuit monitoring the en-
gine is not working correctly. If this oc-
curs, have a Yamaha dealer check the
self-diagnosis system.
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”,

Multi-function display
WARNING
EWA12312
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 anaccident.
The multi-function display is equipped
with the following:

a speedometer


an odometer


two tripmeters (which show the
distance traveled since they were
last set to zero)


a fuel reserve tripmeter (which
shows the distance traveled since
the fuel level warning light came
on)


an oil change indicator (which
flashes when the engine oil should
be changed)


a fuel meter
TIP

Be sure to turn the key to “ON” be-
fore using the “RESET/ SELECT”
button.


When the key is turned to “ON”, all
segments of the display come on
for a few seconds. During this
time, the multi-function display is
performing a self-test.


For the U.K. only: To switch the
speedometer and odometer/trip-
meter displays between kilometers
and miles, press the “RESET/SE-
LECT” button for at least eight sec-onds.

TIPThis model is equipped with a lean an-
gle sensor to stop the engine in case of
a turnover. To start the engine after a
turnover, be sure to turn the main
switch to “OFF” and then to “ON”. Fail-
ing to do so will prevent the engine from
starting even though the engine willcrank when pushing the start switch.
EAUM2322
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.
See page 3-12 for more informa-
tion.
1. Turn the key to “ON” and make
sure that the engine stop switch is
set to“”.
The following warning lights and
indicator light should come on for a
few seconds, then go off.

PERIODIC MAINTENANCE AND ADJUSTMENT

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.
EAUM2592
To check the coolant level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.TIP

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.
TIPThe coolant should be between theminimum and maximum level marks.3. If the coolant is at or below the
minimum level mark, remove the
seat (See page 3-10.), and then
open the coolant reservoir cap.4. Add coolant or distilled water to
raise the coolant to the specified
level, close the coolant reservoir
cap, and then install the seat.
WARNING! Remove only the
coolant reservoir cap. Never at-
tempt to remove the radiator
cap when the engine is hot.
[EWA15161]
NOTICE: 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 anti-
freeze content of the coolant as
soon as possible, otherwise the
effectiveness of the coolant will
be reduced.
