Engine trouble warning light “”
This warning light comes on if an elec-
trical circuit monitoring the engine is not
working correctly. If 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

TIP


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

an odometer

two tripmeters (which show thedistance 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

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
TIP


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”, allof 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 key is turned to “ON”.

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”
TIP

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.
TIP

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
The clock displays when the key is
turned to “ON”.
To set the clock1. Push the “SELECT 1” button for at
least two seconds.

Fuel
Make sure there is sufficient gasoline in
the tank.
WARNING

EWA10881
Gasoline and gasoline vapors are
extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, follow
these instructions.
1. Before refueling, turn off the en-
gine and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the vi-
cinity of sparks, open flames, or
other sources of ignition such as
the pilot lights of water heaters and
clothes dryers.
2. Do not overfill the fuel tank. Stop
filling when the fuel reaches the
bottom of the filler tube. Because
fuel expands when it heats up,
heat from the engine or the sun
can cause fuel to spill out of the
fuel tank.3. Wipe up any spilled fuel immedi-
ately.
NOTICE:
Immediately wipe
off spilled fuel with a clean, dry,
soft cloth, since fuel may deteri-
orate painted surfaces or plastic
parts.

[ECA10071]

4. Be sure to securely close the fuel
tank cap.
WARNING

EWA15151
Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gaso-
line by mouth. If you should swallow
some gasoline or inhale a lot of gas-
oline vapor, or get some gasoline inyour eyes, see your doctor immedi-
ately. If gasoline spills on your skin,
wash with soap and water. If gaso-
line spills on your clothing, change
your clothes.
EAU13390
NOTICE

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
