gine if it is overheating.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 page
6-41 for further instructions.
EAU11534
Engine trouble warning light“”
This warning light comes on or flashes
if a problem is detected in the electrical
circuit monitoring the engine. If this oc-
curs, have a Yamaha dealer check theself-diagnosis system. (See page 3-8
for an explanation of the self-diagnosis
device.)

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 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


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”, “SE-
LECT 2” and “RESET” buttons.


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 key is turned to “ON”.

Odometer and tripmeter modesPush the “SELECT 2” button to switch
the display between the odometer
mode and the tripmeter modes A and B

TIPIndicator“” 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”TIPThe 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.
TIPTo 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).
ClockThe clock displays when the key is
turned to “ON”.

Fuel tank cap To remove the fuel tank cap
1. Insert the key into the lock and turn
it counterclockwise as shown.
2. Turn the fuel tank cap counter-
clockwise and pull it off.
To install the fuel tank cap
1. Insert the fuel tank cap into the
tank opening with the key inserted
in the lock, and then turn the cap
clockwise.
2. Turn the key clockwise, and then
remove it.
TIPThe fuel tank cap cannot be installed
unless the key is in the lock. In addition,
the key cannot be removed if the cap is
not properly installed and locked.
WARNING
EWA10121
Make sure that the fuel tank cap is
properly closed and locked before
riding. Leaking fuel is a fire hazard.
EAU13221
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. When
refueling, be sure to insert the
pump nozzle into the fuel tank filler
hole. 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.

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 in
your 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 differentbrand. Use of unleaded fuel will extend
spark plug life and reduce maintenance
costs.
