NOTICE
●Do not use oils with a diesel
specification of “CD” or oils of
a higher quality than specified.
In addition, do not use oils
labeled “ENERGY CONSER-
VING II” or higher.
●Be sure no foreign material
enters the crankcase.
7. Start the engine, and then let it
idle for several minutes while
checking it for oil leakage. If oil is
leaking, immediately turn the
engine off and check for the cau-
se.
8. Reset the oil change indicator
display according to the follo-
wing procedure.To reset the oil change indicator
display
1. Push the reset button while tur-
ning the key to “ ”.
2. Release the reset button, and the
oil change indicator display will
go off.
TIP
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 chan-
ge 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.

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

NING! Make sure that no
foreign material enters the final
transmission case. Make sure
that no oil gets on the tire or
wheel.

7. Check the final transmission case
for oil leakage. If oil is leaking,
check for the cause.
EAU20070
Coolant
The coolant level should be checked
before each ride. In addition, the coo-
lant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU20103
To check the coolant level
1. Place the vehicle on the centers-
tand.
TIP
●The coolant level must be chec-
ked on a cold engine since the
level varies with engine tempera-
ture.
●Make sure that the vehicle is
positioned straight up when
checking the coolant level. A
slight tilt to the side can result in
a false reading.
2. Check the coolant level in the
coolant reservoir.
TIP
The coolant should be between the
minimum and maximum level marks.

Checking the brake fluid
level
Front brake
1. Minimum level mark
Rear brake
1. Minimum level mark
Insufficient 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 bra-
ke fluid level may indicate worn brake
pads and/or brake system leakage. If
the brake fluid level is low, be sure to
check the brake pads for wear and
the brake system for leakage.
Observe these precautions:
●When checking the fluid level,
make sure that the top of the bra-
ke fluid reservoir is level.
●Use only the recommended qua-
lity brake fluid, otherwise the rub-
ber seals may deteriorate, cau-
sing leakage and poor braking
performance.
●Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performan-
ce.
●Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vapor
lock.
●Brake fluid may deteriorate pain-
ted surfaces or plastic parts.
Always clean up spilled fluid
immediately.
●As 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.

Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the TIP after the periodic maintenan-
ce and lubrication chart. In addition,
have the oil seals of the brake master
cylinder and caliper as well as the
brake hose replaced at the intervals
listed below or whenever they are
damaged or leaking.
●Oil seals: Replace every two
years.
●Brake hose: Replace every four
years.
EAU23101
Checking and lubricating the
cables
The 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 repla-
ce it. WARNING! Damage to the
outer sheath may interfere with
proper cable operation and will
cause the inner cable to rust.
Replace a damaged cable as soon
as possible to prevent unsafe con-
ditions.

Replacing the fuses
1. Main fuse
2. Radiator fan fuse
The main fuse box and the fuse box,
which contains the fuses for the indi-
vidual circuits, are located under
panel B. (See page 6-7).
If a fuse is blown, replace it as
follows.
1. Turn the key to “ ” and turn off
the electrical circuit in question.
2. Remove the blown fuse, and then
install a new fuse of the specified
amperage. WARNING! Do not
use a fuse of a higher ampera-
ge rating than recommended
to avoid causing extensivedamage to the electrical sys-
tem and possibly a fire.
[EWA15131]
3. Turn the key to “ ” and turn on
the electrical circuit in question to
check if the device operates.
4. If the fuse immediately blows
again, have a Yamaha dealer
check the electrical system.

wing parts:
●Headlight bulb
Do not touch the glass part of
the headlight bulb to keep it
free from oil, otherwise the
transparency of the glass, the
luminosity of the bulb, and the
bulb life will be adversely affec-
ted. Thoroughly clean off any
dirt and fingerprints on the
headlight bulb using a cloth
moistened with alcohol or thin-
ner.
●Headlight lens
Do not affix any type of tinted
film or stickers to the headlight
lens.
