Refuel if necessary.
Check fuel line for leakage. 3-9
Engine oil Check oil level in engine.
If necessary, add recommended oil to specified level.
Check vehicle for oil leakage. 6-11
Final transmission oil Check vehicle for oil leakage. 6-13
Coolant Check coolant level in reservoir.
If necessary, add recommended coolant to specified level.
Check cooling system for leakage. 6-14
Front brake Check operation.
If soft or spongy, have Yamaha dealer bleed hydraulic system.
Check lever free play.
Adjust if necessary.

TIPMake sure that the O-ring is properlyseated.
7. Install engine oil drain bolt A, and then tighten both drain bolts to
their specified torques.
8. Refill with the specified amount of the recommended engine oil, and
then install and tighten the oil filler
cap.NOTICE
ECA11671
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 CONSERVING II” or
higher.
Be sure no foreign material en-ters the crankcase.
9. Start the engine, and then let it idle for several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
10. Turn the engine off, and then check the oil level and correct it if
necessary.
To reset the oil change indicator
and oil change tripmeter
TIPThe oil change indicator and oil change
tripmeter can be reset when "OIL
CHANGE" and "OIL TRIP" appear in
the multi-function display. (Seepage 3-3.)

Final transmission oilThe 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 transmis-
sion 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 center- stand.
3. Place an oil pan under the final transmission case to collect the
used oil.
4. Remove the final transmission oil filler cap and its O-ring from the fi-
nal transmission case.

CoolantThe coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAUT3693
To check the coolant level
The coolant level should be checked as
follows before each ride. In addition,
the coolant must be changed at the in-
tervals specified in the periodic mainte-
nance and lubrication chart.1. Place the vehicle on the center- stand.TIP
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to theside can result in a false reading.
2. Open the seat. (See page 3-11.)
3. Check the coolant level in the cool- ant reservoir.
