Engine trouble warning light “
”
This warning light fl ashes or stays on
if an electrical circuit monitoring the
engine is not working correctly. If this
occurs, 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.

WARNING
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:● an odometer● a fuel reserve tripmeter (which
shows the distance traveled since
the bottom segment of the fuel
meter and fuel level warning indi-
cator started fl ashing)● two tripmeters (which show the
distance traveled since they were
last set to zero)● an oil change tripmeter (which
shows the distance traveled since
the last engine oil change)● an oil change indicator (which dis-
plays when the engine oil should
be changed)● a V-belt replacement tripmeter
(which shows the distance trav-
eled since the V-belt was last re-
placed)● a V-belt replacement indicator● an ambient temperature display● a clock● a fuel meter

INSTRUMENT AND CONTROL FUNCTIONS● a brightness control mode
TIP● When the key is turned to “ON”,
all segments and indicators of the
display come on for a few sec-
onds. During this time, the multi-
function display is performing a
self-test.● Be sure to turn the key to “ON”
before using the “SELECT” and
“RESET” buttons except when
setting the brightness mode.
Odometer, fuel tripmeter, tripme-
ters, oil change tripmeter and V-belt
tripmeter modes
Pushing the “SELECT” button switch-
es the display among the odometer
mode “ODO”, the fuel tripmeter mode
“F”, the tripmeter modes “TRIP 1”
and “TRIP 2”, the oil change tripme-
ter mode “OIL TRIP” and the V-belt
change mode “BELT TRIP” in the fol-
lowing order:
ODO → F → TRIP 1 → TRIP 2 → OIL
TRIP → BELT TRIP → ODO
When approximately 1.6 L (0.42 US
gal, 0.35 Imp.gal) of fuel remains in
the fuel tank, the bottom segment of
the fuel meter and fuel level warn-
ing indicator will start flashing, and
the display will automatically change
to the fuel reserve tripmeter mode
“ F” and start counting the distance
traveled from that point. In that case,
pushing the “RESET” button switches
the display to the previous mode.
To reset a tripmeter, select it by push-
ing the “SELECT” button until “Trip” or
“Trip F” begins fl ashing (“Trip” or “Trip
F” will only flash for five seconds).
While “Trip” or “Trip F” is flashing,
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 dis-
play will return to the prior mode after
refueling and traveling 5 km (3 mi).TIPThe display cannot be changed back
to fuel reserve tripmeter “ F” after
pushing the “RESET” button.
OdometerTIP● For the U.K.: For any mode, the
odometer units can be switched
from kilometers to miles by push-
ing the “SELECT” button for 1
second.● If the odometer indicates “-----”,
have a Yamaha dealer check the
multi-function display, as it may
be faulty.
Tripmeters
To reset a tripmeter, select it by push-
ing the “SELECT” button until “TRIP
1” or “TRIP 2” is displayed, and then
push the “RESET” button for at least 1
second.
TIPIf the tripmeter indicates “-----”, have
a Yamaha dealer check the multi-
function display, as it may be faulty.

INSTRUMENT AND CONTROL FUNCTIONS
Oil change tripmeter
To reset the oil change tripmeter, se-
lect it by pushing the “SELECT” button
until “OIL CHANGE” and “OIL TRIP”
are displayed, and then push the “RE-
SET” button for at least 3 seconds.
After resetting, “OIL CHANGE” will
disappear.
Push the “SELECT” button again to
start the oil change tripmeter; the
display changes to V-belt tripmeter
mode.
Oil change indicator “OIL CHANGE”
This indicator will display at the initial
1000 km (625 mi), then at every 6000
km (3750 mi) thereafter to indicate
that the engine oil should be changed.
After changing the engine oil, reset
the oil change tripmeter.
If the engine oil is changed before
the oil change indicator displays
(i.e., before the periodic oil change
interval has been reached), the oil
change tripmeter must be reset after
the oil change for the next periodic oil
change to be indicated at the correct
time.
TIP● If the oil change tripmeter is reset
before the initial 1000 km (625
mi), the next periodic oil change
interval will be at every 6000 km
(3750 mi) thereafter.● If the oil change tripmeter in-
dicates “-----”, have a Yamaha
dealer check the multi-function
display, as it may be faulty.
V-belt replacement tripmeter
To reset the V-belt tripmeter, select it
by pushing the “SELECT” button until
“V-BELT” and “BELT TRIP” are dis-
played, and then push the “RESET”
button for at least 3 seconds. After
resetting, “V-BELT” will disappear.
Push the “SELECT” button again to
start the V-belt tripmeter; the display
changes to ODO mode.
V-belt change indicator “V-BELT”
This indicator comes on at every
20000 km (12500 mi) to indicate that
the V-belt should be replaced.
After replacing the V-belt, reset the V-
belt tripmeter.
If the V-belt is replaced before the
V-belt indicator comes on (i.e., be-
fore the periodic V-belt replacement
interval has been reached), the V-belt
tripmeter must be reset after replacing
the V-belt for the next periodic V-belt
replacement to be indicated at the cor-
rect time.TIPIf the V-belt change indicator displays
“-----”, have a Yamaha dealer check
the multi-function display, as it may be
faulty.
Ambient temperature display “OUT
TEMP”
This display shows the ambient tem-
perature from -10 °C to 40 °C in 1
°C increments. The temperature dis-
played may vary from the ambient
temperature.TIP● If the ambient temperature falls

TIP● Air fi lter and V-belt fi lter
• This model’s air fi lter is equipped with a disposable oil-coated paper element, which must not be cleaned with
compressed air to avoid damaging it.
• The air fi lter element needs to be replaced and V-belt fi lter needs to be serviced more frequently when riding in
unusually wet or dusty areas.● Hydraulic brake service
• After disassembling the brake master cylinder and caliper, always change the fl uid. Regularly check the brake
fl uid level and fi ll the reservoir as required.
• Every two years replace the internal components of the brake master cylinder and caliper, and change the brake
fl uid.
• Replace the brake hose every four years and if cracked or damaged.NO. ITEM CHECK OR MAINTENANCE JOBODOMETER READING
