1. Frost warning indicator
2. Negative symbol
3. Ambient temperature
This display shows the ambient tem-
perature from -30°C (-22°F) to 50°C
(122°F).
The frost warning indicator “
*” auto-
matically comes on if the temperature
is lower than 3°C (37.4°F).
1. Service indicator
Oil change indicator “OIL”
The engine oil should be changed
when this indicator comes on. The
indicator stays on until it is reset. After
changing the engine oil, reset the indi-
cator as follows.
1. While holding the “MODE” and
“SET” buttons pushed, turn the
key to “ON”.
2. Continue holding the “MODE”
and “SET” buttons pushed for
two to five seconds.
3. Release the buttons and the oil
change indicator will go off.
NOTE:
The oil change indicator will
come on at the initial 1000 km
(600 mi) and every 6000 km
(3600 mi) thereafter.
If the engine oil is changed before
the oil change indicator comes on
(i.e. before the periodic oil change
interval has been reached), the
indicator must be reset after the
oil change for the next periodic oil
change to be indicated at the
correct time. After resetting, the
indicator will come on for two
seconds. If the indicator does not
come on, repeat the procedure.

Safety is an obligation of the owner.
Periodic inspection, adjustment and
lubrication will keep your vehicle in
the safest and most efficient condi-
tion possible. The most important
points of inspection, adjustment, and
lubrication are explained on the follo-
wing pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a
general guide under normal riding
conditions. However, DEPENDING
ON THE WEATHER, TERRAIN, GEO-
GRAPHICAL LOCATION, AND INDIVI-
DUAL USE, THE MAINTENANCE
INTERVALS MAY NEED TO BE
SHORTENED.

To install the spark plug
1. Spark plug gap
1. Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to spe-
cification.
2. Clean the surface of the spark
plug gasket and its mating surfa-
ce, and then wipe off any grime
from the spark plug threads.
3. Install the spark plug with the
spark plug wrench, and then
tighten it to the specified torque.
NOTE:
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is
1/4~1/2 turn past finger tight. Howe-
ver, the spark plug should be tighte-
ned to the specified torque as soon
as possible.
4. Install the spark plug cap.
5. Install the storage compartment
by installing the bolts.
6. Close the seat.

Engine oil
The engine oil level should be chec-
ked before each ride. In addition, the
oil must be changed at the intervals
specified in the periodic maintenance
and lubrication chart and when the
service indicator light comes on.
To check the engine oil level
1. Place the scooter on the centers-
tand.
NOTE:
Make sure that the scooter is positio-
ned straight up when checking the oil
level. A slight tilt to the side can result
in a false reading.
2. Start the engine, warm it up for
several minutes, and then turn it
off.
Tightening torque:
Spark plug:
12.5 Nm (1.25m•kgf, 9.05 ft•lbf)
Spark plug gap:
0.8 - 0.9 mm (0.031 - 0.035 in)

a higher quality than specified.
In addition, do not use oils
labeled “ENERGY CONSER-
VING II” or higher.
Be sure no foreign material

Final transmission oil
The final transmission case must be
checked for oil leakage before each

Yamaha dealer check and repair the
scooter. In addition, the final trans-
mission oil must be changed as
follows at the intervals specified in the
periodic maintenance and lubrication
chart.
1. Start the engine, warm it up by
riding the scooter for several
minutes, and then stop the engi-
ne.
2. Place the scooter on the centers-
tand.
3. Place an oil pan under the final
transmission case to collect the
used oil.
1. Final transmission oil filler cap
4. Remove the oil filler cap and
drain bolt to drain the oil from the
