will reset itself automatically and the
display will return to the prior mode af-
ter refueling and traveling 5 km (3 mi).
NOTE:

The display cannot be changed back to
“TRIP F” after pushing the “RESET”
button.
Fuel meter
With the key in the “ON” position, the
fuel meter indicates the amount of fuel
in the fuel tank. The display segments
of the fuel meter disappear towards “E”
(Empty) as the fuel level decreases.
When the fuel level reaches the bottom
segment near “E”, the fuel level warn-
ing indicator and the bottom segment
will flash. Refuel as soon as possible.
Coolant temperature meter
With the key in the “ON” position, the
coolant temperature meter indicates
the temperature of the coolant. The
coolant temperature varies with chang-
es in the weather and engine load. If
the top segment and coolant tempera-
ture warning indicator flash, stop thevehicle and let the engine cool. (See
page 6-40.)
CAUTION:

ECA10020
Do not operate the engine if it is
overheated.
Oil change indicator “OIL”
This indicator flashes at the initial 1000
km (600 mi), then at 5000 km (3000 mi)
and every 5000 km (3000 mi) thereafter
to indicate that the engine oil should be
changed.
After changing the engine oil, reset the
oil change indicator. (See page 6-13.)
If the engine oil is changed before the
oil change indicator comes on (i.e. be-
fore the periodic oil change interval hasbeen reached), the indicator must be
reset after the oil change for the next
periodic oil change to be indicated at
the correct time. (See page 6-13.)
The electrical circuit of the indicator can
be checked according to the following
procedure.
1. Set the engine stop switch to “”
and turn the key to “ON”.
2. Check that the indicator comes on
for a few seconds and then goes
off.
3. If the indicator does not come on,
have a Yamaha dealer check the
electrical circuit.
NOTE:

The oil change indicator may flash
when the engine is revved with the
scooter on the centerstand, but this
does not indicate a malfunction.
V-belt replacement indicator
“V-BELT”
This indicator flashes every 20000 km
(12500 mi) when the V-belt needs to be
replaced.
The electrical circuit of the indicator can
be checked according to the following

procedure.
1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “”.
2. If the indicator does not come on,
have a Yamaha dealer check the
electrical circuit.
Self-diagnosis device
This model is equipped with a self-diag-
nosis device for various electrical cir-
cuits.
If any of those circuits are defective, the
multi-function display will indicate a
two-digit error code.
If the multi-function display indicates
such an error code, note the code num-
ber, and then have a Yamaha dealer
check the vehicle.
CAUTION:

ECA11790
If the multi-function display indi-
cates an error code, the vehicle
should be checked as soon as pos-
sible in order to avoid engine dam-
age.
This model is also equipped with a
self-diagnosis device for the immobiliz-er system.
If any of the immobilizer system circuits
are defective, the immobilizer system
indicator light will flash, and then the
multi-function display will indicate a
two-digit error code when the key is
turned to “ON”.
NOTE:

If the multi-function display indicates er-
ror code 52, this could be caused by
transponder interference. If this error
appears, try the following.
1. Use the code re-registering key to
start the engine.
NOTE:

Make sure there are no other immobi-
lizer keys close to the main switch, and
do not keep more than one immobilizer
key on the same key ring! Immobilizer
system keys may cause signal interfer-
ence, which may prevent the engine
from starting.
2. If the engine starts, turn it off, and
try starting the engine with the
standard keys.
3. If one or both of the standard keys
do not start the engine, take thevehicle, the code re-registering
key and both standard keys to a
Yamaha dealer and have the stan-
dard keys re-registered.
If the multi-function display indicates
any error codes, note the code number,
and then have a Yamaha dealer check
the vehicle.

1. Push the “SELECT” button and
“RESET” button together for at
least two seconds.
2. When the hour digits start flashing,
push the “RESET” button to set the
hours.
3. Push the “SELECT” button, and
the minute digits will start flashing.
4. Push the “RESET” button to set
the minutes.
5. Push the “SELECT” button and
then release it to start the clock.

Fuel
Make sure that there is sufficient fuel in
the tank. Fill the fuel tank to the bottom
of the filler tube as shown.
WARNING

EWA10880

Do not overfill the fuel tank, oth-
erwise it may overflow when the
fuel warms up and expands.

Avoid spilling fuel on the hot en-
gine.
CAUTION:

ECA10070
Immediately wipe off spilled fuel
with a clean, dry, soft cloth, sincefuel may deteriorate painted surfac-
es or plastic parts.
EAU33520
CAUTION:

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 regular unleaded gaso-
line with a research octane number of
91 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a different brand
or premium unleaded fuel. Use of un-
leaded fuel will extend spark plug life
and reduce maintenance costs.
EAU13442
Catalytic converters
This vehicle is equipped with catalytic
converters in the exhaust system.
WARNING

EWA10860
The exhaust system is hot after op-
eration. Make sure that the exhaust
system has cooled down before do-
ing any maintenance work.
CAUTION:

ECA10700
The following precautions must be
observed to prevent a fire hazard or
other damages.

Use only unleaded gasoline.
The use of leaded gasoline will
cause unrepairable damage to
the catalytic converter.

Never park the vehicle near pos-
sible fire hazards such as grass
or other materials that easily
burn.

Do not allow the engine to idle
too long.

Ignition circuit cut-off system
The ignition circuit cut-off system (com-
prising the sidestand switch and brake
light switches) has the following func-
tions.

It prevents starting when the side-
stand is up, but neither brake is ap-
plied.

It prevents starting when either
brake is applied, but the sidestand
is still down.

It cuts the running engine when the
sidestand is moved down.
Periodically check the operation of the
ignition circuit cut-off system according
to the following procedure.
