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.
EAUT1934
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”,
or if the warning light remains on, have
a Yamaha dealer check the electrical
circuit.

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.
Odometer and tripmeter modes
A brief push (less than one second) on
the “RESET/SELECT” button switches

3mode “ODO” and the tripmeter modes
“TRIP 1” and “TRIP 2” in the following
order:
ODO → TRIP 1 → TRIP 2 → ODO
When approximately 1.6 L (0.42 US
gal, 0.35 Imp.gal) of fuel remains in the
fuel tank, the odometer display will au-
tomatically change to the fuel reserve
tripmeter mode “F-TRIP” and start
counting the distance traveled from that
point, and the last segment of the fuel
meter will start flashing. In that case,
pushing the “RESET/SELECT” button
switches the display between the vari-
ous tripmeter and odometer modes in
the following order:
F-TRIP → TRIP 1 → TRIP 2 → ODO →
F-TRIP
To reset a tripmeter, select it by push-
ing the “RESET/SELECT” button briefly
(less than one second), and then push
the button again for at least three sec-
onds. If you do not reset the fuel re-
serve tripmeter manually, it will reset
itself automatically and the display will
return to the prior mode after refueling
and traveling 5 km (3 mi).Oil change indicator
This indicator flashes at the initial 1000
km (600 mi), then at 3000 km (1800
mi), and every 3000 km (1800 mi)
thereafter to indicate that the engine oil
should be changed.
After changing the engine oil, reset the
oil change indicator.
TIPThe oil change indicator can only be re-
set when “OIL” flashes in the multi-function display.
To reset the oil change indicator, select
it by pushing the “RESET/SELECT”
button briefly (less than one second),
and then pushing the button again for at
least five seconds. When the oil changeindicator stops flashing and stays on,
release the “RESET/SELECT” button
within three seconds; the indicator will
go off.
TIPIf the oil change indicator still flashes af-
ter the reset procedure has been com-pleted, repeat the reset procedure.
Fuel meter
The fuel meter indicates the amount of
fuel in the fuel tank. The display seg-
ments of the fuel meter disappear to-
wards “E” (Empty) as the fuel level
decreases. When the last fuel meter
segment starts flashing, refuel as soon
as possible.

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, followthese 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 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.
EAU43421
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

spark plug life and reduce maintenance
costs.
EAU13445
Catalytic converters This vehicle is equipped with catalytic
converters in the exhaust system.
WARNING
EWA10862
The exhaust system is hot after op-
eration. To prevent a fire hazard or
burns:

Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.


Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.


Make sure that the exhaust sys-
tem has cooled down before do-
ing any maintenance work.


Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up ofheat.
NOTICE
ECA10701
Use only unleaded gasoline. The use
of leaded gasoline will cause unre-
pairable damage to the catalyticconverter.

OPERATION AND IMPORTANT RIDING POINTS
5-3

EAU16810
Tips for reducing fuel con-
sumption Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:

Shift up swiftly, and avoid high en-
gine speeds during acceleration.


Do not rev the engine while shifting
down, and avoid high engine
speeds with no load on the engine.


Turn the engine off instead of let-
ting it idle for an extended length of
time (e.g., in traffic jams, at traffic
lights or at railroad crossings).
EAU16830
Engine break-in There is never a more important period
in the life of your engine than the period
between 0 and 1000 km (600 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1000 km (600 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided.
EAUM2560
0–500 km (0–300 mi)
Avoid prolonged operation above 1/3
throttle.
500–1000 km (300–600 mi)
Avoid prolonged operation above 1/2
throttle. NOTICE: After 1000 km (600
mi) of operation, the engine oil must
be changed, the oil filter cartridge or
element replaced, and the oil strain-
er cleaned.
[ECA10321]
1000 km (600 mi) and beyond
The vehicle can now be operated nor-
mally.NOTICE
ECA10270
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealercheck the vehicle.
