Engine oilThe engine oil level should be
checked before each ride. In addition,
the oil must be changed at the inter-
vals specified in the periodic mainte-
nance and lubrication chart and when
the oil change indicator light comes
on.To check the engine oil level
1.Place the scooter on the center-
stand.
NOTE:
Make sure that the scooter is posi-
tioned 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.

To reset the oil change indicator
light
1.Turn the key to ÒONÓ.
2.Hold the reset button pushed for
two to five seconds.
3.Release the reset button, and
the oil change indicator light will
go off.1.Reset button
NOTE:
If the engine oil is changed before the
oil change indicator light comes on
(i.e. before the periodic oil change
interval has been reached), the indi-
cator light must be reset after the oil
change for the next periodic oil
change to be indicated at the correct
time. To reset the oil change indicator
light before the periodic oil change
interval has been reached, follow the
above procedure, but note that the
indicator light will come on for 1.4
seconds after releasing the reset but-
ton, otherwise repeat the procedure.

Final gear oilThe final gear case must be checked
for oil leakage before each ride. If
any leakage is found, have a
Yamaha dealer check and repair the
scooter. In addition, the final gear 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
engine.
2.Place the scooter on the center-
stand.NOTE:
Make sure that the scooter is posi-
tioned straight up when checking the
oil level. A slight tilt to the side can
result in a false reading.3.Place an oil pan under the final
gear case to collect the used oil.

CoolantThe coolant reservoir is located
under the battery cover. (See page

dures.)
To check the coolant level
1.Place the scooter on a level sur-
face and hold it in an upright
position.NOTE:
8The coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
8Make sure that the scooter is
positioned straight up when
checking the coolant level. A
slight tilt to the side can result in
a false reading.

Observe these precautions:
8When checking the fluid level,
make sure that the top of the
master cylinder or brake fluid
reservoir is level.
8Use only the recommended qual-
ity brake fluid, otherwise the rub-
ber seals may deteriorate, caus-
ing leakage and poor braking
performance.1.Minimum level markREARRecommended brake fluid:
DOT 4
8Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking perfor-
mance.
8Be careful that water does not
enter the master cylinder or
brake fluid reservoir when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock.
8Brake fluid may deteriorate paint-
ed surfaces or plastic parts.
Always clean up spilled fluid
immediately.
8As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if
the brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause.

EAU03607
Checking the brake fluid
levelInsufficient brake fluid may allow air
to enter the brake system, possibly
causing it to become ineffective.
Before riding, check that the brake
fluid is above the minimum level mark
and replenish if necessary. A low
brake fluid level may indicate worn
brake pads and/or brake system
leakage. If the brake level is low, be
sure to check the brake pads for
wear and the brake system for leak-
age.1.Minimum level mark FRONT

Changing the brake fluidHave a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and lubrica-
tion chart. In addition, have the oil
seals of the master cylinder and
caliper as well as the brake hoses
replaced at the intervals listed below
or whenever they are damaged or
leaking.
8Oil seals: Replace every two
years.
8Brake hoses: Replace every four
years.
EAU02962
Checking and lubricating the
cablesThe operation of all control cables
and the condition of the cables
should be checked before each ride,
and the cables and cable ends
should be lubricated if necessary. If
a cable is damaged or does not move
smoothly, have a Yamaha dealer
check or replace it.
EW000112
wDamage to the outer sheath may
interfere with proper cable opera-
tion and will cause the inner cable
to rust. Replace a damaged cable
as soon as possible to prevent
unsafe conditions.
Recommended lubricant:
Engine oil
EAU03118
Lubricating the front and
rear brake leversThe pivoting points of the front and
rear brake levers must be lubricated
at the intervals specified in the peri-
odic maintenance and lubrication
chart.
Recommended lubricant:
Lithium-soap-based grease
(all-purpose grease)
