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:

Engine trouble warning light “”
This warning light comes on when an
electrical circuit monitoring the engine
is defective. When this occurs, have a
Yamaha dealer check the self-diagno-
sis system.
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.
NOTE:

This warning light will come on whenthe key is turned to “ON” and the start
switch is pushed, but this does not indi-
cate a malfunction.

NOTE:


The multi-function display can be
set to the basic mode or the mea-
surement mode.

Tripmeter A will automatically re-
set to zero when changing from
the basic mode to the measure-
ment mode or vice versa.
Basic mode:

a speedometer (which shows the
riding speed)

an odometer (which shows the to-tal 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 since
the fuel level warning light came
on)

a clock

a self-diagnosis device
Measurement mode:

a speedometer (which shows the
riding speed)

a distance-compensation tripme-
ter (which shows the accumulated
distance traveled since set to zero
and which can be calibrated to pro-
vide a more accurate tripmeter
reading)

a stopwatch (which shows the time
that has been accumulated since
the start of stopwatch measure-
ment)

a self-diagnosis device
NOTE:


Be sure to turn the key to “ON” be-
fore using the “SELECT 1”,“SELECT 2” and “RESET” but-
tons.

When the key is turned to “ON”, all
of the display segments of the
multi-function display will appear
and then disappear, in order to test
the electrical circuit.

For the U.K. only: To switch the
speedometer and odometer/trip-
meter displays between kilometers
and miles, press the “SELECT 2”
button until the display changes af-
ter the main switch is turned to
“ON”.

NOTE:

Indicator “ ” comes on when tripmeter
A is selected, and indicator “ ” comes
on when tripmeter B is selected.If the fuel level warning light comes on
(see page 3-2), the display will auto-
matically change to the fuel reserve
tripmeter mode “F” and start counting
the distance traveled from that point. In
this case, push the “SELECT 2” button
to switch the display between the vari-
ous tripmeter and odometer modes in
the following order:
fuel reserve tripmeter “F”
→
odometer
→
tripmeter A
→
tripmeter B
→
fuel re-
serve tripmeter “F”
NOTE:

The fuel level warning light may not
function accurately while riding off road
as the fuel level reading changes due to
the movement and inclination of the ve-
hicle.
If the fuel level warning light comes on
while riding in the measurement mode,
change to the basic mode and push the
“SELECT 2” button to display the fuel
reserve tripmeter.
NOTE:

To change from the measurement
mode to the basic mode, the stopwatch
and the distance-compensation tripme-
ter must be stopped.
To reset a tripmeter, select it by push-
ing the “SELECT 2” button, and then
push the “RESET” button for at least
one second. If you do not reset the fuel
reserve tripmeter manually, it will reset
itself automatically and the display will
return to the prior mode after refueling
and traveling 5 km (3 mi).
Clock
Turn the key to “ON”.NOTE:

When setting the clock, push the
“SELECT 1” button to increase the dig-
its or “SELECT 2” button to decrease

CAUTION:

ECA11400
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,
as well as to the exhaust system.
Your Yamaha engine has been de-
signed to use premium unleaded gaso-
line with a research octane number of
95 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a different
brand. Use of unleaded fuel will extend
spark plug life and reduce maintenance
costs.
EAU13431
Catalytic converter
This model is equipped with a catalytic
converter in the exhaust system.
WARNING

EWA10860
The exhaust system is hot after op-
eration. Make sure that the exhaust
system has cooled down before do-
ing any maintenance work.
CAUTION:

ECA10700
The following precautions must be
observed to prevent a fire hazard or
other damages.

Use only unleaded gasoline.
The use of leaded gasoline will
cause unrepairable damage to
the catalytic converter.

Never park the vehicle near pos-
sible fire hazards such as grass
or other materials that easily
burn.

Do not allow the engine to idle
too long.
