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 an
accident.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.

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.

WARNING
EWA10570


Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the mo-
torcycle with excessively worn
tires decreases riding stability
and can lead to loss of control.


The replacement of all wheel-
and brake-related parts, includ-
ing the tires, should be left to aYamaha dealer, who has the
necessary professional knowl-
edge and experience.


It is not recommended to patch
a punctured tube. If unavoid-
able, however, patch the tube
very carefully and replace it as
soon as possible with a high-
quality product.
EAU21941
Spoke wheels
WARNING
EWA10610
The wheels on this model are not de-
signed for use with tubeless tires.
Do not attempt to use tubeless tires
on this model.To maximize the performance, durabil-
ity, and safe operation of your motorcy-
cle, note the following points regarding
the specified wheels.

The wheel rims should be checked
for cracks, bends or warpage, and
the spokes for looseness or dam-
age before each ride. If any dam-
age is found, have a Yamaha
dealer replace the wheel. Do not
attempt even the smallest repair to
the wheel. A deformed or cracked
wheel must be replaced.


The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse han-
dling characteristics, and a short-
ened tire life.
