“km/L”: The average distance that
can be traveled on 1.0 L of fuel is
shown.
 “L/100 km”: The average amount
of fuel necessary to travel 100 km
is shown.
 “MPG”: The average distance that
can be traveled on 1.0 lmp. gal of

the “SELECT” button for one second.
To reset the average fuel consumption,
push the “RESET” button for at least
one second.
TIP After resetting the average fuel
consumption, “_ _._” will be
shown until the vehicle has trav-

 When MPG is selected, no units
indicator will be displayed.
Oil chan ge tripmeter mo de
The oil change tripmeter shows the
distance traveled since it was last reset
(i.e., since the last oil change).
The oil change indicator “OIL” will flash
at the initial 1000 km (600 mi), then at
6000 km (3500 mi) and every 6000 km
(3500 mi) thereafter to indicate that the
engine oil should be changed.
After changing the engine oil, reset the
oil change tripmeter and the oil change
indicator. To reset them both, select
the oil change tripmeter, and then push
the “RESET” button for one second.
Then, while “OIL” and the oil change tripmeter are flashing, push the “RE-
SET” button for three seconds. The oil
change indicator will be reset.
If the engine oil is changed before the
oil change indicator comes on (i.e., be-
fore the periodic oil change interval has
been reached), the oil change tripmeter
must be reset for the next periodic oil
change to be indicated at the correct
time.

The V-belt replacement indicator “V-
BELT” will flash at every 18000 km
(10500 mi) thereafter to indicate that
the V-belt should be replaced.
After replacing the V-belt, reset the V-
belt replacement tripmeter and the V-
belt replacement indicator. To reset
them both, select the V-belt replace-
ment tripmeter, and then push the
“RESET” button for one second. Then,
while “V-BELT” and the V-belt replace-
ment tripmeter are flashing, push the
“RESET” button for three seconds. The
V-belt replacement indicator will be re-
set.
If the V-belt is replaced before the V-
belt replacement indicator comes on
(i.e., before the periodic V-belt replace-
ment interval has been reached), the V-
belt replacement tripmeter must be re-
set for the next periodic V-belt replace-
ment to be indicated at the correct
time. Self-d
iagnosis mo de
This model is equipped with a self-di-
agnosis device for various electrical
circuits.
If a problem is detected in any of those
circuits, the engine trouble warning
light will come on and the display will
indicate an error code.
If the display indicates any error codes,
note the code number, and then have
a Yamaha dealer check the vehicle.

FuelMake sure there is sufficient gasoline in
the tank.
WARNING
EWA10882
Gasoline an d gasoline vapors are
extremely flammab le. To avoid fires
an d explosions an d to re duce the
risk of injury when refuelin g, 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 spille d fuel with a clean,
d ry, soft cloth, since fuel may
d eteriorate painte d surfaces or
plastic parts.
[ECA10072]
4. Be sure to securely close the fuel tank cap.
WARNING
EWA15152
Gasoline is poisonous an d can
cause injury or d eath. Handle gaso-
line with care. Never siphon gasoline
b y mouth. If you shoul d swallow
some gasoline or inhale a lot of gas-
oline vapor, or g et some gasoline in
your eyes, see your doctor imme di- ately. If g
asoline spills on your skin,
wash with soap an d water. If gaso-
line spills on your clothin g, chan ge
your clothes.
EAU53013
NOTICE
ECA11401
Use only unlea ded g asoline. The use
of lead ed g asoline will cause severe
d amag e to internal en gine parts,
such as the valves an d piston rin gs,
as well as to the exhaust system.Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
95 or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand or premium unleaded fuel. Use
of unleaded fuel will extend spark plug
life and reduce maintenance costs.
